Aerogels are lightweight solid materials that are made from organic or inorganic materials, or as composites, and are being studied as advanced materials for various applications. The use of aerogels in everyday applications is limited due to their high cost and complex preparation process. Drying aerogels can be laborious, requiring significant energy and resources. When prepared as composites, aerogels can enhance mechanical properties. They can also be tailored to release bioactive molecules, such as growth factors or antibiotics, to speed up the healing process. However, there are challenges in using aerogels for wound healing. Large-scale production may be costly, limiting their use in clinical settings. Additionally, the mechanical properties of aerogels may not be suitable for all wound types. Further research is needed to overcome these challenges and optimize the use of aerogels in clinical settings. This research investigates different types of wound dressings, commercial wound dressings, chitosan-based aerogels, and the properties and applications of aerogels in wound dressings. The unique properties of aerogels, such as their high porosity, large surface area, and biocompatibility, make them ideal candidates for enhancing the wound healing process. Studies have shown that aerogels made from chitosan can improve cell adhesion, proliferation, and migration, resulting in quicker and more efficient wound closure. Furthermore, the controlled release of bioactive molecules from aerogels can further improve the healing process by reducing inflammation and promoting tissue regeneration.

 Proverbs or proverbs are short words in rhyme or prose that include an important and extensive part of the literature and social culture of the people. The use of proverbs is very common in popular culture. The content of proverbs is mostly moral, social concepts, advice, wisdom, politics, orders and life experiences. Proverbs are sometimes allegorical and summarized phrases from stories that, while short, have a deep and lingering meaning; And sometimes they are a compact of previous knowledge and wisdom. Considering that in most cases proverbs do not have a specific speaker and an obvious time of origin and have been passed down orally from one generation to another over the years, sometimes the speakers have made mistakes or deviations in their vocabulary when using them. The principle of the proverb is no longer compatible with its practical and old (original) meaning. In this research, we have tried to find the correct and original form of the proverb "The star of becoming easy".

 The method of this research is based on document review and library studies. In this research, first, by referring to hundreds of important and reliable historical and literary works, we collected what was said about the stars Sohail and Saha in astronomy, literary images of poets, works of astronomers and commentators, and ancient Persian and Arabic proverbs. Then by categorizing and analyzing them, we have deduced the original form of the proverb.

 In this research, by examining how the knowledge, beliefs and descriptions of the predecessors about the stars Sohail and Soha are reflected in the scope of the history of Persian culture and literature, the authors have shown that the star Sohail in ancient Persian literature is a symbol of brilliance and greatness, and this star is contrary to Saha, which is a symbol of wisdom and invisibility, has never been described with attributes such as rare and invisible, and it has not been used ironically, and contrary to what was known in recent centuries that Sohail blows once a year and is rarely seen, this night star It was seen many times and the ancients never considered it as a symbol of invisibility or rareness.

 Based on the findings, the authors of the article have come to the conclusion that according to evidence such as Naser Khusro"s poem, which compares the simultaneity of its fame and disappearance to the star of Saha, and the verses that compare its appearance to Sohail"s star, and its disappearance and rareness to the star of Saha. have attributed, the correct form of the proverb "the star of Sohail" is "the star of Soha".

Drug release systems based on nanotechnology reduce side effects, increase drug release time, and control drug release. Polymeric nanoparticles that are used as pharmaceutical nanocarriers lead to increasing the solubility and stability of drugs.Increasing concerns about the safety of chemical drugs and additives has caused a demand for the use of bioactives. Drug concentration is one of the important factors for investigating cytotoxicity, which can play a role in cell death and anti proliferation. Therefore, effective drug release by nanocarriers eliminates poor and unstable solubility in cells. The designed nanocarrier causes long-term drug release in the cancerous tumor environment, which, as a result, increases cytotoxicity. In most of the new researches, nanocarriers were made by double emulsion method, which makes the shape of nanoparticles stable and uniform and also prevents the acceleration of nanoparticles during the drug release process. In this research, the cytotoxicity analysis of new nanocarriers made in breast cancer cell line has been analyzed.

The utilization of nanoparticles as drug carriers is of utmost importance due to their ability to effectively transport drugs to specific areas of the body at the appropriate time. Incorporating anticancer agents into nanoparticle-based drug delivery systems has emerged as a highly efficient approach for targeting cancer cells. These systems possess the capability to penetrate cells more effectively, enabling the precise combination of drugs within the cells. Moreover, they take advantage of the enhanced permeability and retention (EPR) effect, allowing for better accumulation of drugs at tumor sites. Particle size is a critical factor influencing the efficacy of anticancer nanocarriers. The zeta potential range of -30 to +30 millivolts is particularly favorable for designing nanocarriers, as it ensures their stability in the bloodstream and prolonged circulation. Many studies have indicated that the optimal particle size for targeted drug release falls below 300 or 200 nanometers. This size range facilitates efficient drug diffusion among tissues and enhances permeability. This study, for the first time, focuses on analyzing particle size obtained through dynamic light scattering and evaluating the surface charge potential to enhance the release of anticancer drugs.

Curcumin is a yellow polyphenol extracted primarily from the plant Curcuma longa, but also from several other members of the ginger family.Many nanoscale systems have been extensively used for drug loading and release to get around curcumin's low bioavailability and aqueous solubility, highlight its functional properties, and broaden its applications in the pharmaceutical industry.Chitosan has been used as a natural biopolymer extensively for many years. Its polycationic properties, biocompatibility, biodegradability, non-toxicity, and lack of allergenicity all led to studies on it. The main focus in the discovery of curcumin involves its anti-cancer properties. It is well known that curcumin inhibits the signal transmission of cancer cell growth and thus angiogenesis and also causes tumor cell apoptosis. The modification of chitosan for various applications can be easily achieved due to the abundant active groups (NH2 and OH) in the main chainFor the release of curcumin, numerous chitosan-based nanocarriers with distinct properties have been developed, including nanocomposites, nanoemulsions, nanotubes, and nanofibers. The controlled release of the drug is to maintain the optimal therapeutic concentration of the drug in the blood, which increases the shelf life and duration of activity of drugs with a short half-life. Controlled drug release makes the drug release rate predictable and repeatable for prolonged release drugs. Therefore, the development of colloidal systems for curcumin release encapsulation is a promising strategy to overcome the limitations of drug release. The physical and chemical characteristics of chitosan-based nanocarriers, including surface charge, morphology, encapsulation driving force, and release characteristics, are examined in this study and the effectiveness of chitosan-based nanocarriers for pharmaceutical applications is determined by these characteristics.

Chitosan has been widely used as a natural biopolymer. The modification of chitosan for various applications can be easily achieved due to the abundant active groups (NH2 and OH) in the main chain. Controlled drug release makes the drug release rate predictable and repeatable for prolonged release drugs. Drug delivery systems prepared from nanoparticles show several advantages, including improved efficiency and reduced toxicity. Using drug delivery systems based on nanoparticles loaded with anti-cancer agents is an effective method for targeting cancer cells. These systems, with the ability to penetrate better inside the cells, combine the drug in a targeted way in the cells. Also, due to the enhanced permeability and retention (EPR), the possibility of better accumulation of drugs in the tumor site is provided. In most researches, the suitable particle size for the targeted release of drug nanocarriers has been reported to be less than 300 or 200 nm. This amount is suitable for the application of drug release for diffusion among tissues and causes the effect of increasing permeability. In this study, for the first time, it examines and analyzes the particle size and zeta potential (surface charge) of chitosan-based nanocarriers through dynamic light scattering and electron microscope tests in improving the release of the antitumor drug, 5-fluorouracil.

Chitosan (CS) as a natural polymer has been widely studied in the field of wound healing due to its useful properties including non-toxicity, excellent biological properties, biodegradability and promotion of collagen deposition. However, low mechanical strength and moderate antibacterial properties are disadvantages that limit its further clinical application. Chitosan is a copolymer with a linear chain of diglucosamine and N-acetyl beta-glucosamine, which is produced by deacetylation of chitin. The deacetylation leads to the formation of cationic amine groups, which is actually a prerequisite for the antibacterial function of chitosan. Many researchers have adopted the use of nanotechnology, especially metal nanoparticles (MNPs), in order to improve the mechanical strength and specific antibacterial properties of chitosan composites with promising results. In addition, chitosan naturally acts as a reducing agent for metal nanoparticles, which can also reduce cytotoxicity. Therefore, chitosan in combination with metal nanoparticles exhibits antibacterial activity, excellent mechanical strength and anti-inflammatory properties and has great potential to accelerate the wound healing process. It is worth mentioning that the mechanism of action of metal nanoparticles is dose-dependent and excessive concentration can cause significant cytotoxicity. The loading efficiency and release rate of metal nanoparticles changes according to the manufacturing process. Hence, further investigation of dosage and preparation methods is a necessary prerequisite for clinical applications.

Hydrogels are three-dimensional networks of hydrophilic polymers capable of absorbing and retaining significant amounts of fluids, which are also widely applied in wound healing, cartilage tissue engineering, bone tissue engineering, release of proteins, growth factors, and antibiotics. In the past decades, a lot of research has been done to accelerate wound healing. Hydrogel-based scaffolds have been a recurring solution in both cases, although their mechanical stability remains a challenge, some of which have already reached the market. To overcome this limitation, the reinforcement of hydrogels with fibers has been investigated. The structural similarity of hydrogel fiber composites to natural tissues has been a driving force for the optimization and exploration of these systems in biomedicine. Indeed, the combination of hydrogel formation techniques and fiber spinning methods has been very important in the development of scaffold systems with improved mechanical strength and medicinal properties. Hydrogel has the ability to absorb secretions and maintain moisture balance in the wound. In turn, the fibers follow the structure of the extracellular matrix (ECM). The combination of these two structures (fiber and hydrogel ) in a scaffold is expected to facilitate healing by creating a suitable environment by identifying and connecting cells with the moist and breathing space required for healthy tissue formation. Modifying the surface of fibers by physical and chemical methods improves the performance of hydrogel composites containing

Due to the variety of their structural makeup, hydrogels polymer networks that are saturated with water are used in a wide range of industries, including medicine, pharmaceuticals, cell or biomolecule separation, and biosensors. Hydrogels have received a lot of attention recently because of their flexible and stable structure in transition phenomena. In comparison to traditional hydrogels, the polymer network of nanocomposite hydrogels has better elastic and rheological properties. Hydrophilic and hydrophobic drugs can both be present in hydrogels at the same time, which is why they are used to release both types of medications. Hydrogels are used in many medical applications, including tissue engineering, contact lenses, wound dressings, and the release of therapeutic agents, because they have a structure similar to the extracellular matrix and the capacity to absorb water. Drugs with a short half-life have an extended shelf life and duration of action due to the controlled release of the drug, which helps to maintain the best therapeutic concentration of the drug in the blood. For drugs with a prolonged release, controlled drug release makes the drug release rate dependable. This article discusses the properties of hydrogel nanocomposites and how they can be used to create targeted drug delivery systems.

The global rise in cancer cases highlights the need for effective therapeutic strategies that not only reduce side effects but also enhance performance and efficacy. Conventional treatments such as medical methods, radiation therapy, and chemotherapy have limitations and safety concerns. To address these issues, drug delivery systems (DDSs) or nano drug delivery systems( NDDSs) have been proposed to release drugs specifically on cancer cells while sparing normal tissue. pH-responsive systems have been developed to improve the selectivity of anticancer drugs by taking advantage of the lower pH of tumor sites. This approach minimizes side effects and overdosage and is made possible by enhanced permeability and retention (EPR), which increases drug accumulation at tumor sites. Particle size is a crucial factor in nanocarriers containing anticancer drugs, and in this study, for the first time, the particle size of nanocarriers (nano systems)was analyzed using electron microscopy to improve the release of anticancer drugs.

One of the most important scientific treasures of any country is the collection of short and long articles written by experts in various fields and published in publications. Writing articles in Iran does not have a long history. Before the constitution, most of the research texts were the same contents that were written in tazkires and other books, which of course had no scientific and documented basis. After the constitution, the quality of literary research was transformed and skepticism became common and literary researchers tried to improve the quality of literary research by referring to original works and using criticism techniques. In the field of satire, the first articles written are related to the introduction of Obeid Zakani and humor in his works. And in general, it should be said that the word humor in the sense and meaning of the term that we use today was first used in researches that introduced Obaid Zakani and his special way of expressing Lataif, a way that was used with others. It was different and attention to the element of social criticism is   prominent in them.

In this research, firstly, by using famous Persian websites such as Noormags.ir, Magiran.com, Humanities Comprehensive Portal, Academic Jihad Database (SID.ir) and... articles on the subject of Obeid Zakani. It was found that there are about 71 articles that use the name Obaid Zakani or the word mouse and cat in the title or abstract or keyword. Then, we have classified and analyzed the articles in thematic and historical categories, and the result of the research is shown on the graph. It should be noted that in this research, only scientific articles were examined and counted, and conference articles and books were not considered.

Looking at the researches in the field of humor, we realize that the first researches in this field are about the introduction of Obeid and his works as the most important humorist before the constitution, but with the passage of about a century, scientific and non-scientific articles are still being written about Obeid. The review of articles related to Obeid Zakani provides us with valuable information about the research process in different years, which can be used to observe the interest and scientific level of researchers related to specific topics and approaches of Obeid research in different decades. In addition, it can help researchers in this field to avoid repetitive research and to have better access and familiarity with humorous sources for conducting new research, and to recognize useful and necessary sources from non-useful ones.In this research, we have reviewed the scientific articles related to Obeid zakani that have been written since the beginning until today. Examined the articles in terms of structure and content and divided them into six historical periods and seven subjects of Obeid's humor, Obeid's biography, introduction of works, content and theme, rhetorical and satirical techniques, comparative studies and review of literary theories in Obeid's works; We have reviewed and classified; We have introduced repetitive and useless researches as well as useful and scientific researches and have shown the historical course of articles in different decades. Studies show that in the first years, the subject of the articles is often the introduction of Obeid Zakani and Obeid's social satire and introduction of his works. These articles mostly have a descriptive approach and have little benefit from analysis and reasoning. The language of the articles is often literary; Writers tend to write essays and generalize and do not go into details. In the sixties, only one article was written, which is better in terms of quality than the articles of the previous period. In the 1970s, in addition to dealing with Obeid's life and satire, Obeid's works were introduced and compared and compared with the works of others such as Hafez and Yaghmai Jandaghi. is not. In the seventies, the subject of most of the articles is the introduction of Obaid's works, and the articles still have a descriptive approach and do not deal with specific analysis. In terms of structure, they lack a scientific structure in the modern sense. Mohammad Jaafar Mahjoub is the most important researcher of this period, in the field of introduction of Obeid's works and its manuscripts, who contributed to a better and more scientific understanding of Obeid Zakani and his works with his articles. His articles are among the most influential articles in the field of Obed studies. In the 1980s, scientific articles grew significantly in terms of content and structure, and diverse and new topics such as comparative studies, studies of children's and adolescent literature, and literary theories were also effective in looking at Obeid's works in a new way, but these articles were written by beginners and They often lack analyzes and arguments and presentation of scientific statistics.

Conclusion :

 Most of the articles in the field of Obed studies were written in the 1990s, and in terms of quality, these articles have a variety of topics and scientific structures, and have more analytical power than previous articles. However, they have weaknesses, such as: not mastering the theories and examining Obeid's works based on literary theories, not providing accurate statistics on the amount of use of satirical techniques, great importance on the structure of the article and its stereotyping, and less attention to the content, arguments, and analyzes Scientific. After the 1990s, the most articles in the field of Obed studies were written in the 1970s. Although the articles of the eighties are less than the articles of the seventies; In terms of the quality and diversity of the subject, they have a more scientific structure and content than the previous articles. With all this, it is suggested that researchers in the field of Obed studies, by limiting the scope of research and focusing on details and using statistics and citing scientific sources and data, master the modern methods of comparative research and literary theories, pay more attention to analytical and argumentative aspects, to Help improve the scientific level of articles.

Chitosan is derived from non-toxic renewable resources and acts as a compatible and effective biomaterial. As an anti-cancer drug, quercetin has low solubility. Chitosan-based nanocarriers are of particular interest because they can enhance the bioavailability and anticancer efficacy of quercetin by passively or actively targeting cancer tissues. On the other hand, the active centers in the main structure of chitosan enable the creation of nanocarriers with various cross-links on the surface. Thus, this leads to targeted release in the patient's body and avoids damage to healthy tissue. On the other hand, chitosan is a pH-sensitive biopolymer, which changes the hydrophilic and hydrophobic balance in the polymer network according to pH conditions and reacts to the acidic environment around cancer cells to collapse the structure. As a result, it causes the controlled release of quercetin in cancerous tumors and reduces its harmful effects on normal cells. This study investigated the effectiveness of chitosan-based nanocarriers in improving and promoting the release of the anti-cancer drug quercetin.

The process of curing the epoxy resins with hardeners leads to an increase in crosslink density and the properties of the hardened resin are affected, depending on the curing conditions. To improve the final properties of epoxy resins, the use of organic and inorganic nanoparticles has been suggested. One of the recently attended nanoparticles is graphene oxide and its derivatives. In this paper, various models presented in the curing kinetics of epoxy/ graphene oxide hybrid compounds have been evaluated and the reasons for the deviation of laboratory and experimental results with modeling results have been explained. Also, comparison of each of these models with experimental results has shown that Sestak-Berggren and Kamal model has higher adaptation to experimental results than the other models and can be used as a reliable basis for describing the curing process of epoxy resins containing graphene oxide nanoparticles.

Epoxy thermoset resins have been used in the composite, construction, electronics, adhesive and coatings industries due to their good thermal, electrical and chemical properties. Distribution and dispersion of nanoparticles in polymer matrix is an important and influential issue in the mechanical properties of epoxy nanocomposites. Curing kinetics equations are used to evaluate and optimize the production process, and degradation kinetics modeling has become widely used as an essential tool for engineers to reduce costs and product quality. Addition of modified carboxyl and amine groups to pure epoxy resin does not change the curing reaction mechanism and also modifying the surface of nanodiamond increases the curing rate of epoxy nanocomposite. Investigation of hybrid thermal stability of epoxy nanocomposites in the presence of nanodiamonds and graphene oxide showed that the simultaneous presence of two different types of nano material can increase the thermal stability. In this research, the effect of adding nano diamonds and modified nano diamonds on morphology, mechanical and rheological properties, and modeling of curing kinetics and degradation kinetics and tribological properties have been investigated.

The scientific articles that are published in the periodicals of any country are among the most important scientific treasures of that country. One of the issues that has attracted the attention of researchers and literary critics is the analysis of humor and the works of humorists, as one of the most important tools for understanding the thoughts and cultures and social and political characteristics of different societies. The literature of every society, with the help of the element of humor, goes against the unfavorable situations of the society, and on its way, it causes changes in different aspects, and this affects such social, political and cultural fields and is mutually affected by them. Therefore, satirical studies provide us with valuable information about various political, social and cultural issues of different societies. On the other hand, with the growth and development of comparative studies, the researchers of different nations have investigated and compared humor and the works of their humorists with different nations and investigated their differences and similarities and the causes and contexts of these similarities and differences as well as their impact on They have shown interest in each other. Today, we see many comparative studies in the field of humor studies. By examining and analyzing the content of comparative humor research articles, this research shows the quantity and quality of these articles, and to what extent they are written based on the scientific principles of comparative studies, and what are their strengths and weaknesses. 

This research has analyzed 39 comparative scientific articles in the field of humor research using the content analysis method. First, by using famous Persian websites such as Noormags.ir, Magiran.com, Humanities Comprehensive Portal, Academic Jihad Scientific Database (SID.ir), etc. Either the abstract or the keywords of comparative literature and humor have been used, it was determined, then the articles were reviewed and evaluated according to the criteria approved by comparative literature, and the results were determined on the graph. 

Pathology of comparative satirical essaysIn order to explain the meaning of comparative literature, we should linger more in front of its concept, to remove what the comparative researchers have wrongly put in the category of comparative literature. In this section, the pathology of comparative research in the field of humor has been discussed under the two topics of subject matter and research methodology, and cases such as methodology in research, incomplete understanding of comparative literature and only finding similarities and differences in works, having creativity and innovation, addressing generalizations. And inattention to details, lack of use of reliable scientific sources, ignorance or knowledge of the principles of comparative literature have been examined in researches. 

A high frequency of articles written in the field of comparative studies, inspired by the word (adaptation), have limited themselves to comparing the similarities and differences of two works and have chosen the title (comparative review) for their articles; Now that comparative literature has important principles that it is international and intercultural and interdisciplinary, examining the influence and influences of cultures and works of literature on each other, important factors and contexts in the influence of one culture on another culture and why and how the similarities and differences are, and also examining The transformative elements are among the most important of these principles. In the list of sources of most of the comparative articles published in the field of humor studies, not even one of the reliable and important sources of the field of comparative studies can be seen, and even in some cases, no comparison has been made regarding the similarities and differences, and throughout the article, only the word comparative is mentioned in the title. The articles written in the field of comparative literature lack structure and scientific content in most cases, the research method is not given, or the term (descriptive analysis based on comparison) is sufficient, and only a handful of articles refer to the American or French school of comparative literature is mentioned. The articles that have the necessary knowledge about comparative literature are those that, while referring to the concept of comparative studies, have introduced their research outside of the comparative field.

Epoxy resins are one of the most important thermosetting polymers that applied in the industries of coatings, buildings, and high performance composite materials due to their physical , mechanical properties and good chemical resistance. Curing kinetics equations are used to optimized epoxy resins and epoxy nanocomposites and also, studying the kinetics of curing can increased the quality of the final product. Changes in the glass transition temperature can affected the conversion of the epoxy resin, and the presence of carbon nanofibers in the matrix helps to improved the crosslinking process. Adsorption of curing agent molecules into carbon nanofibers reduced the concentration of carbon nanofibers and also, surface modification of nanofibers reduced the activation energy and improved the curing rate. In this research, the effect of adding carbon nanofibers and modified carbon nanofibers on morphology and mechanical , rheological properties, activation energy, reaction rate, degree of curing, heat flow, and curing kinetics modeling has been investigated.

In this study, the effect of elastomeric nanoparticles on the thermal and cure kinetic behavior of epoxy resin was investigated. The thermal behavior of epoxy resins and epoxy nanocomposites were investigated at three different temperatures of 65, 70, and 75 oC under isothermal conditions . For this purpose, scanning electron microscopy and differential scanning calorimeter tests were used. Morphological examination of epoxy nanocomposites showed that the appearance of elastomeric nanoparticles is spherical and shows good dispersion in the epoxy matrix at both 0.5% and 1%.Examination of the heat flow of epoxy resin and epoxy nanocomposite showed that it initially increases and decreases after reaching a maximum point and by adding elastomeric nanoparticles the degree of curing, the total enthalpy of the reaction and the peak heat flow time increased .Curing kinetics modeling showed that epoxy resin and epoxy nanocomposites follow the nth-order model and with increasing the presence of elastomeric nanoparticles, the activation energy decreased and this type of nanoparticles plays a catalytic role in reaction with epoxy resin and laboratory data are in good agreement with the results of curing kinetics modeling.
