The male uro-genital tract is susceptible to gram-negative bacterial infections that produce a state of inflammation, particularly in the testis and epididymis. Development of germline stem cells into motile spermatozoa takes place in these organs and thus any impairment therein has a direct effect on male fertility. A number of factors are known to impair male fertility including environmental...

This paper, with No.22 State Farm, Agricultural Division No.2, XPCC as the example and under support of GIS, takes cultivated land plot as the evaluation unit and chooses 13 influence factors from five aspects of nutrient of cultivation layer, physical and chemical properties of cultivation layer, soil management, climate conditions and obstacle factor to establish desert oasis cultivated land ...

The fertility or sterility of a male depends on several factors, among which are the chemical constituents of the semen, the number, morphological integrity, motility, metabolism and viability of the spermatozoa. These factors, of course, are interrelated in effecting fertility or probability of fertilization. Although in normal matings the number of spermatozoa in the ejaculate is much greater...

extraction of oil from poor quality pistachios results in increased add-value. in this study, the performance of different solvents in recovery of valuable oil and meal from the pistachio sample contaminated with aflatoxin was investigated and some chemical properties of the extracted oil were determined. the pistachio nut oil was extracted by three solvent systems including n-hexane (non- pola...

12 Complex relationships exist between different components of the organic farm and 13 the quantity and quality of the end products depend on the functioning of the whole 14 system. As such, it is very difficult to isolate soil fertility from production and 15 environmental aspects of the system. Crop rotation is the central tool that integrates 16 the maintenance and development of soil fertil...

Background Infertility is a medical and social condition and has a considerable impact on a person’s quality of life (QoL). Due to this impact, nowadays health-systems not only focus on morbidity and mortality but also on quality of life and well-being. The aim of the study was to determine the QoL of women with fertility problem, and identify factors associated with poor QoL. MaterialsAndMetho...

The reaction of CsN3 with GaS and S at elevated temperatures results in Cs2Ga2S5. Its crystal structure was determined from single-crystal X-ray diffraction data. The colorless solid crystallizes in space group C2/c (no. 15) with V = 1073.3(4) Å(3) and Z = 4. Cs2Ga2S5 is the first compound that features one-dimensional chains ∞(1)([Ga2S3(S2)(2-)] of edge- and corner-sharing GaS4 tetrahedra. The...

Dairy farming now needs more records to be kept for quality assurance as well as for management. Herd fertility management is best brought about through the use of computerised records for each animal that integrate fertility, health and production. The development of dairy information systems over the last 25 years has allowed the creation of databases that give rise to "standards" of performa...

For simplicity, we adopt the following rules: n denotes an element of N, X, X1 denote sets, r, p denote real numbers, s, x0, x1, x2 denote real numbers, S, T denote real normed spaces, f , f1, f2 denote partial functions from R to the carrier of S, s1 denotes a sequence of real numbers, and Y denotes a subset of R. The following propositions are true: (1) Let s2 be a sequence of real numbers an...
