The pine sawfly Diprion jingyuanensis Xiao and Zhang (Hymenoptera: Diprionidae) is a serious pest of Pinus tabulaeformis Carr. in the Shanxi, Gansu, Inner Mongolia provinces P. R. China. sex pheromone D. was shown to be propionate ester 3,7-dimethyl-2-tridecanol. Virgin females contained an approximate 1:3 blend precursors erythro-(2S,3S,7R/S 2R,3R,7R/S)-3,7-dimethyl-2-tridecanol threo-(2S,3R,7...

BACKGROUND When chromatin diminution occurs during a cell division a portion of the chromatin is eliminated, resulting in daughter cells with a smaller amount of genetic material. In the parasitic roundworms Ascaris and Parascaris, chromatin diminution creates a genetic difference between the soma and the germline. However, the function of chromatin diminution remains a mystery, because the vas...

Flavin-containing monooxygenase (FMO) 3 is the predominant FMO isoform in adult human liver; however, little is known about its expression in common laboratory species. Studies have shown FMO3 levels to be sex-dependent in mouse liver, but not in human liver. The current study was undertaken to determine the expression of FMO3 in liver and kidney microsomes from multiple species, and to determi...

This study examined the relationship of ambivalent sexism, political conservatism, demographic variables (age, education, and gender), and prior sexual experience to Turkish men s and women s attitudes toward women who engage in premarital sex. Participants included 124 Turkish undergraduate students and 60 nonstudent Turkish adults. Benevolent but not hostile sexism uniquely predicted more neg...

background: sex education is one of the challenging areas of educational systems that has always been accompanied by many problems due to some obstacles and constraints. this has led to occurrence of many behavioral problems and deviations. the aim of this study was to determine the sex education gaps in university curriculum from the students' perspective. methods: this was a descriptive-...

objective(s):to determine the fetal discernment in suspected cases of sex linked recessive disease in the first trimester of pregnancy. materials and methods: after collection of 100 chorionic villi samples, the dnas were extracted and baby gender was determined. meanwhile, after increasing the sensitivity, the system was able to detect the sex of each cell which was obtained by biopsy. results...

smaller vocal tract larger vocal tract Pitch and /s/ variation are not fundamentally and directly linked to gender or sex, but have a complex range of indexical links which can be called upon to perform a variety of affects and character types. Effect of sex on variation is indirect and mediated by affects, stances, persona styles, character types (Ochs 1992; Eckert 1989, 2008, 2014; Eckert & M...

Cooperative learning (CL) is a learning style that refers to small, heterogeneous groups of students working together to achieve a common goal. This involves student-student interaction within small groups in a way that each group member’s success is dependent on the group’s success. Self-regulated learning (SRL) style believe on what ‘knowing’ is and how one ‘come...

Theory predicts that occasional sexual reproduction in predominantly parthenogenetic organisms offers all the advantages of obligate sexuality without paying its full costs. However, empirical examples identifying and evaluating the costs and benefits of rare sex are scarce. After reviewing the theoretical perspective on rare sex, we present our findings of potential costs and benefits of occas...
