Resistance literature evokes the resistance of truth against falsehood and encourages perseverance in goals and ideals, which of course is not limited to time and place and is one of the most important categories that poets have at times devoted a large part of their texts to it during different periods. The way poets have referred to these concepts in their poems is an issue that has occupied the minds of many researchers. The purpose of this descriptive-analytical study is to analyze the effects of stability and awakening in the poems of Al-Barghouthi to extract examples of awakening and stability, to categorize and analyze how to deal with these concepts. The results of this study indicate that Al-Barghouti, with the help of his poems, calls the people to wake up and stand against oppression and uses his pen to awaken and make his nation aware, hoping that with his poetry he will wake up the neglected human society. He has been able to use symbols and myths to show the current situation of Palestine and to give objectivity to the Palestinian identity and their awakening.

This study examines the role of trust, commitment, and learning orientation in management. پژوهش The type of research is descriptive in terms of purpose and implementation. The statistical community calls it the "Gilan Large Water Treatment Plant" of 100 people in 1398, which is simple and simple sampling of 79 people in front of the table. The theoretical model has 5 variables or hidden structures. These variables include: trust, commitment, learning orientation, logistics services and service innovation. It is between independent indicators namely trust, commitment and tendency to learn with There is a positive and significant relationship between the dependent indicators of the effectiveness of logistics services in the Gilan Water Treatment Plant. The relationship between the two variables was investigated using Pearson correlation coefficient. The validity of the questionnaire was confirmed by the research experts and Cronbach's alpha coefficient was used to estimate the reliability, which is above 0.7. Statistical analysis was performed using SPSS and AMOS softwares on questionnaire data. Structural equation path analysis test was performed on the main and specific hypotheses of regression method in Amos software with confidence level of 0.99. In a nutshell, identifying the needs of employees in the organization is the key to building their relationships and managing them. Therefore, the variables of trust, commitment and learning tendency not only increase the effectiveness of logistics services but also the role of the organization in performance. And can be boosted by either of them Even the simultaneous improvement of these variables together provided the right conditions for the organization to grow.

Bloodstream infections (BSI) are dangerous and if not  treated appropriately will be accompanied by high mortality. the aim of this study was to  determine the frequency of different etiological agents of BSI and their resistance to  commonly used antibiotics.

This study performed by 129 positive blood culture samples  collected during 2009 to 2010 from patients of tehran besat hospital. Antibiotic susceptibility testing was performed by using disk diffusion method as per clinical and laboratory standards institu (CLSI) guideline. Data analysed by Chi-square test and SPSS  soft ware. P value of <0.05 was determined as significant.

The most common causes of BSI were coagulase-negative staphylococcus  (CONS) and E.coli 45(34.9%), 38(29.5%) respectively. Infections with proteus vulgaris was rare 2 (1.6%). Prevalence of gram negative infections in comparison with gram positive infections was (1.58:1). The highest resistance was demonstrated as: Penicillin 73.6% - Ampicillin 66.6% -Tetracyclin 58.9%. The highest susceptibility was demonstrated as Gentamicin and Imipenem 68.3%,65.9% respectively.

BSI caused by gram negative bacteria is 1.5 fold more than gram positive bacteria. In our hospital CONS and E.coli are more common etiological agents of BSI (64% of all infections). Vancomycin are suitable antibiotic for treatment of CONA and S.aureus infections.
