The use of different methods of battle, the tremendous technological advances by the enemies and the speed and effect of military actions have significantly increased the success rate of the enemy in military operations. America and its allies have been there, and in most of these countries, especially America, lightning operations are considered one of their tactics and have been considered in most offensive actions. Therefore, it can be said that there is concern about the continuation of operations against the military actions of the enemy. To solve this problem, a problem was raised for this research. What are the factors affecting the operational continuity of the ground battle in the future war? To answer the mentioned problem, the main goal of this research was "to find the effective factors on the operational continuity of the ground battle in the future war". The type of "applied" research has been done using quantitative and qualitative data sets with a mixed approach, so the approach of this research is a mixed approach and the case-contextual method has been used. The statistical community of this research consists of two parts, the first part is the expert community and the second part is the general research community. The statistical population of the first part is 12 people and the second part is 107 people. The researcher's findings from library and field studies and interviews with experts include the preparation of 5 questionnaires, the results of this research are: statistics... factors affecting operational continuity of ground combat in the future war. In the following, 5 practical and research proposals are presented based on it

The use of different methods of fighting, tremendous technological advances by the enemies, and the speed and effect of military actions, the percentage of success of the enemy in military action has increased to a significant extent. America and its allies have been there, and in most of these countries, especially the United States, lightning operations are considered one of their tactics and have been taken into account in most of the aggressive actions. Therefore, it can be said that there is a concern of operational continuity against the enemy's military actions. To solve this problem, a problem was raised for this research; What are the features of the future war effective on the operational continuity of ground combat? In order to answer the mentioned problem, the main goal of this research was determined to "achieve the characteristics of the future war effective on the operational continuity of ground combat". The type of "applied" research was done using quantitative and qualitative data sets with a mixed approach, so the approach of this research is a mixed approach and the case-contextual method is used. The statistical population of this research consists of two parts, the first part is the expert community and the second part is the general research community. The statistical population of the first part is 12 people and the second part is 107 people. The researcher's findings from library and field studies and interviews with experts consist of the preparation of 5 questionnaires, the results of which are; Statistics of 28 features affecting operational continuity of ground combat in the future war. In the following, 5 practical and research proposals are presented based on it.

Pediatric palliative care defined as any intervention that focuses on relieving suffering, slowing the progression of disease, and improving quality of life at any stage of disease is rather a new concept in Iran's health care system. This study aims at needs assessment of delivering pediatric palliative care from the viewpoint of pediatric nurses and physicians. 

211 pediatricians and pediatric nurses participated in this descriptive study. A self-administered pre-tested standardized questionnaire was used as the study material. Needs assessment of delivering pediatric palliative care was investigated through 28 Likert questions mainly on three domains including National, Family and Child (scores ranging from 28 to 140). To confirm the items on the questionnaire, confirmatory factor analysis was used. Mean scores of each domain was compared using Mann-Whitney test and Kruskal-Wallis. Correlations were studied through Pearson Correlation Test. Data was analyzed by SPSS version 21.

Overall score of necessity for delivering pediatric palliative care was 130.43. The item "Considering ethical issues while contacting the family" had the highest score (4.4±0.28) in the Family domain." In two other domains, National and Child, the items " Trying to have a peaceful death in the late stages of life " and " To benefit equally from palliative care" had the highest scores respectively (4.2±0.52 and 4.1±0.4).

The results of this study revealed the necessity of delivering pediatric palliative care in Iran. Additionally, considering ethical issues in palliative medicine and providing justice-oriented care were indicated as important subjects in this area. In the end, a pediatric palliative care model was designed based on the total score and the items of the questionnaire.

Mucormycosis is an aggressive and life-threating fungal infection that affects patients with uncontrolled diabetes mellitus (DM) or compromised immune system. The most common symptom of rhinocerebral mucormycosis is sinusitis, and if the infection spreads beyond the sinus, more severe symptoms such as blindness, seizure, and death may occur.

We describe a case of rhinocerebral mucormycosis successfully treated in an 11-year-old boy with uncontrolled DM and neglected sinusitis with sudden blindness.

 Patients with poorly controlled or insulin-dependent DM who experience periods of ketoacidosis are more likely to develop mucormycosis. Therefore, correct diagnosis and timely referral of patients greatly affect the prognosis of the disease and the treatment process.

This paper proposes the implementation of a novel predictive control scheme known as adaptive generalized predictive control (AGPC) in the actuation system of a high-powered test rig. Through the use of actuation system, the required torque for simulating different conditions can be applied to the tested gearboxes. The accurate and precise control of this system is of great importance as it affects the overall performance of the test rig. The considered actuation system in this investigation is electro-hydraulically driven with nonlinear and uncertain characteristics. The performance of the proposed control scheme in different conditions of the parametric uncertainty as well as presence of disturbances are evaluated and the results are discussed. The results confirmed the superior performance of the proposed scheme in different studied conditions.

Agricultural lands Cadastre can help to design an operational cropping pattern for each farm and provide production planning, agricultural distribution systems, optimal soil and water management in line with the country's comprehensive and macro agricultural strategies. In this study, it was used to design a comprehensive and operational cropping pattern in Shahreza City of Isfahan Province under a decision support system by developing a multi-objective mathematical programming model. Due to the wide range of information and the necessity of their processing, as well as fast and accurate access to the results of planning model, the structure of this system was formed by integrating the descriptive and spatial database, programming platform, and optimization software package to solve the model and generate the necessary reports. The results showed that despite the area under cultivation of multi-objective model for cereals and kitchen garden crops decreased by 37% and 8%, however, cereal production decreased only 27% and kitchen garden crop production increased by 70%. This increasing in productivity has been realized due to using crop varieties, crop management, irrigation method, and land suitability of each crop in each farm in the planning structure used in this study. Due to generating details of the cropping pattern for each farm through cadastre data, application of results for irrigation planning and control of groundwater resources discharging is recommended in the study area.

The calcifying odontogenic cyst (COC) is a rare cystic lesion, mainly affecting the anterior aspect of the jaws. It is usually discovered in unexpected settings and can be clinically observed as a painless and well-defined lesion. The COC may be associated with other odontogenic tumors, such as odontomas. Nearly 50% of COCs are associated with an unerupted tooth, most often a canine. The most unique features of this pathology are histopathological features, including a cystic lining with characteristic ghost epithelial cells with a tendency for calcification. Radiological examinations often reveal a radiolucent and unilocular lesion, sometimes associated with radiopaque lesions. Pathological assessments are required for the final diagnosis. Management is through complete excision with annual radiographic monitoring for five years.

Here, we report a classic case of COC in the left mandibular region associated with an extremely displaced impacted canine in a 16-year-old girl.

Although uncommon, COCs are frequently associated with impacted teeth. The radiolucencies associated with impacted teeth have different effects on the surrounding structures and require different treatment plans, depending on the type of the lesion.

This research sought to examine the mediating role of psychological capital in the relationship between authentic leadership and work engagement among school principals and teachers. The study had a descriptive, correlational design. The statistical population of the study was comprised of all school principals and teachers in Aleshtar (located in Lorestan Province) in school year 2016-17 from among whom 295 individuals were selected through random simple sampling method. It is worth mentioning that the sample size was determined via the Cochran formula. The instruments included Utrecht Work Engagement Scale (UWES) (2003), Luthan’s Psychological Capital Questionnaire (PCQ) (2007), and Authentic Leadership Questionnaire (ALQ) (Walumbwa, et al., 2008). Evaluation of the proposed model was performed through SEM and using SPSS20 and AMOS20. Results demonstrated that the proposed structural model provided a good fit to the data and there was a significant, positive relationship between authentic leadership, psychological capital, and work engagement. Furthermore, the results showed that the direct relationship between authentic leadership and psychological capital was significant. This also holds true for the direct relationship between psychological capital and work engagement. Nevertheless, the direct relationship between authentic leadership and work engagement was not significant. Findings also indicated that the indirect relation between authentic leadership and work engagement through moderation of psychological capital was significant. Accordingly, although authentic leadership had a significant, positive relationship with work engagement; however, this association was meaningful through the mediation of psychological capital and this variable had no effect on personnel work engagement by itself.

The purpose of this study was survey the effect of cognitive-behavioral intervention on perfectionism and guilt feeling in student.

Field experimental research design and a pretest - posttest control group was used, statistical society was all of students in first half year of 90-91 academic year in Esfahan Daneshpajoohan university. Of 14 sample in the experimental group and 14 sample in the control group were selected through random multistage sampling and also measurement tools is Ahvaz Perfectionism Scale and the Eysenck guilt test which in order made by Najarian, Atari and Zargar(1378) and Eysenck. Statistical method for data analysis was multivariate analysis of covariance.

The result of MANCOVA indicated that cognitive-behavioral inventory significantly reduces perfectionism and guilt feeling. Furthermore, this effect was sustained at one month follow up.

cognitive-behavioral inventory reduces perfectionism and guilt feeling by correcting people’s thought about benefits and harms of perfectionism thought and infrastructure believes. It is suggested that according to the impact of perfectionism in all aspects of individual and social life, affected people be identified in childhood and necessary actions be done about them.

Different studies have shown that there is no relation between sperm chromatin stability and fertilization rate in both IVF and ICSI patients. However, the relation between SDS tests, as a detergent, along with DTT as reducer of disulphide bridges has not been studied so far in ICSI patients. Since different concentrations of DTT can induce different degrees of sperm chromatin decondensation, the aim of this study was to evaluate the effect of different concentrations of DTT on sperm chromatin decondensation in IVF and ICSI cases.

During this study, 85 patients were divided into two groups according to their treatment procedure (IVF or ICSI).Semen samples of each patient was evaluated for sperm chromatin tests including SDS, SDS+EDTA & SDS+DTT for assessment of free thiole groups level (-SH), amount of non covalent bond between Zn and thioles(-SH Zn SH-) and levels of disulfide bond (-S-S-) in sperm chromatin, respectively. In this study, seminal fructose concentration, corrected seminal fructose level and true corrected fructose level as indicators of seminal vesicle function on sperm chromatin stability were assessed.

No correlation was observed between any of the above tests and rate of fertilization, both in IVF and ICSI cases. However, in IVF patients, a significant correlation was observed between SDS, SDS+DTT test and seminal fructose level, while in ICSI patients, only a significant correlation was observed between SDS+DTT and corrected or true fructose concentration.

Since no correlation was observed between sperm chromatin test and fertilization rate, it is suggested that the chromatin status of these samples are adequate for fertilization to take place and extent of disulphide bridges has no effect on fertilization rate. However, the amount of disulphide bound present in sperms of ICSI and IVF patients are different, and this difference is related to seminal vesicle performance in these patients.

Background and

Ânthrax is a zoon otic disease common between animals and man which is caused by a gram positive spore forming bacillus, known as Bacillus Ânthracis. This disease is still one of the causes of health problems in developing countries. Çhahar Mahal Bakhtyari state is one of the agricultural and animal breeding centers of Ïran and annually many of the human and animals die of this disease.

 study done on so Çutaneous anthrax patients at infectious disease ward of Âyatollah Kashani hospital in shahre Kord.

The findings were as follows: - Ït was more prevalent in the age groups of 11-20 years old, and there were more cases in males than females. - Most of the patients were infected in summer season, and 96% of them were from rural areas. 32% of cases had history of contact with animals and 12% insect bites - The most infected organs were face, hands and arms. 100% of cases had non pitting oedema, and 80% had necrotic lesions with surrounding erythema. Fever, headache and regional lymphadenopathy was observed in 78%, 64% and 42% respectively. - Helpful laboratory diagnostic criterias were ËSR, Leucocytosis and positive ÇRP, but final confirmation is based on preperation of an smear from the exudates and culture on mediums. - Âll the patients were treated with penicillin and 92% of the patients were relieved of fever three days after initiation of treatment. Ïn this study the mortality rate was zero percent and the most common side effect was the secondary infection at the site of the wound. Çonclusion: Ït is concluded that in endemic areas, all wound cases with nonpitting oedema with or without necrotic lesions should be considered for anthrax, and more knowledge about the disease in the developing countries and development of medical researches specially for the purpose of prevention would help in decline of the number of infected cases.
