AIM： to compare the prevalence of hepatitis viral markers among soldiers from turkey, blood donors from Northern Cyprus, and soldiers from Northern Cyprus. MEtHODS： Hepatitis B surface antigen （HBsAg）, anti-HCV and anti-human immunodeficiency virus （HIV） seroprevalence, HBV DNA, HCV RNA and HCV genotyping among soldiers from turkey （group Ⅰ ）, civil blood donors from Northern Cyprus （group Ⅱ ）, and soldier candidates from Northern Cyprus （group Ⅲ） were studied and compared to one another. In total, 17 545 cases （13 546 males and 3999 females with a mean age of 34.5 ± 10.3 year, group Ⅰ = 11234, group Ⅱ = 5057, and group Ⅲ = 1254） were included into the study. RESULtS： Among all cases, HBsAg positivity rates were 2.46%, anti-HCV was 0.46% and anti-HIV was 0.00%. HBV DNA was 2.25%, HCV RNA was 0.33% in all groups. HBsAg positivity rates were 2.16% in group Ⅰ, 3.00% in group Ⅱ and 2.71% in group Ⅲ. there was a significant difference between group Ⅰ and group Ⅱ （χ^2= 6.11, P = 0.047 〈 0.05）. Anti-HCV positivity rates were 0.45% in group Ⅰ, 0.45% in group Ⅱ, and 0.56% in group Ⅲ. Genotypes of HCV were 1b and 1a in group Ⅰ, 1b, 1a and 2 in group Ⅱ, and tb, 1a in group Ⅲ. HBsAg carrier rates were 2.20% in females and 2.53% in males. Anti-HCV prevalence was 0.38% in females and 0.48% in males. HBsAg positivity rates were 2.53% in individuals younger than 50, and 1.47% in older than 50. there was a significant difference between the two groups （χ^2 =23.48, P = 0.001） CONCLUSION： Prevalences of HBsAg, HCV and HIV infections in Northern Cyprus population are similar to those of turkey.

the main purpose of this paper is to explore the influence of predation on the spread of a disease developed in the prey population where we assume that the prey has a social *** memory of the prey and the predator measured by the time fractional derivative plays a crucial role in modeling the dynamical response in a predator–prey *** memory can be modeled to articulate the involvement of interacting species by the presence of the time fractional derivative in the considered *** the purpose of studying the complex dynamics generated by the presence of infection and the time-fractional-derivative we split our study into two cases. the first one is devotedto study the effect of a non-selective hunting on the spread of the disease, where the localstability of the equilibria is investigated. Further the backward bifurcation is obtainedconcerning basic reproduction rate of the infection. the second case is for explaining theimpact of selecting the weakest infected prey on the edge of the herd by a predator onthe prevalence of the infection, where the local behavior is scrutinized. Moreover, for thegraphical representation part, a numerical simulation scheme has been achieved usingthe Caputo fractional derivative operator.

We experimentally demonstrate the C-band wavelength conversion using four-wave mixing in a 17-mm-long silicon-on-insulator waveguide pumped by a dispersed mode-locked femtosecond laser pulse. the idler can be observed with an incident average pump power lower than 4 dBm, and about 35 nm of conversion bandwidth from 1530nm to 1565nm is measured by using a 1550-nm pump wavelength. the pulse-pumped efficiency is demonstrated to be higher, by more than 22 dB, than the cw-pumped efficiency. the conversion efficiency variations with respect to the pump and signal powers are also investigated.

Background: Post-hepatectomy liver failure(PHLF) is a leading cause of postoperative mortality after liver surgery. Due to its significant impact, it is imperative to understand the risk stratification and preventative strategies for PHLF. the main objective of this review is to highlight the role of these strategies in a timeline centered way around curative resection. Data sources: this review includes studies on both humans and animals, where they addressed PHLF. A literature search was conducted across the Cochrane Library, Embase, MEDLINE/Pub Med, and Web of Knowledge electronic databases for English language studies published between July 1997 and June 2020. Studies presented in other languages were equally considered. the quality of included publications was assessed using Downs and Black’s checklist. the results were presented in qualitative summaries owing to the lack of studies qualifying for quantitative analysis. Results: this systematic review with 245 studies, provides insight into the current prediction, prevention, diagnosis, and management options for PHLF. this review highlighted that liver volume manipulation is the most frequently studied preventive measure against PHLF in clinical practice, with modest improvement in the treatment strategies over the past decade. Conclusions: Remnant liver volume manipulation is the most consistent preventive measure against PHLF.

炭纤维增强混凝土能用来感知温度,其因在于短炭纤维的P-型传导性引起的塞贝克(Seebeck)效应所致。通过测量添加炭纤维或矿质掺和物(飞灰、硅土粉)前后六种波特兰水泥基混凝土的热电功率,研究了炭纤维增强轻质混凝土热敏的能力及其矿质掺合物对Seebeck效应的影响。结果表明:炭纤维增强轻质混凝土具有类似于炭纤维增强标准混凝土的Seebeck效应,只是Seebeck系数因掺合了矿粉而减低。掺有矿粉的炭纤维增强轻质混凝土可用作建筑物的热传感器.
