Nutrition is an important aspect of public health because it is linked to many significant diseases and health problems. This work is part of the promotion of traditional foods from the Democratic Republic of Congo in general and in the province of Bandundu, in particular by assessing the selenium content and the antioxidant capacity of wild edible mushrooms. Methanolic extracts from selected mushrooms were characterized for their chemical fingerprint by TLC and their in vitro antioxidant activities using ABTS, DPPH assays. Phytochemical screening revealed the presence of alkaloids, free amines, steroids and terpenes in all species. However, Auricularia delicata and Pleurotus tuberregium contain flavonoids. All extracts displayed a good radical-scavenging activity at the concentration range 1 - 300 μg/mL in the following order: Auricularia delicata > Lentinus cf cladopus > Pleurotus tuberregium > Marasmius buzungolo > Schizophillum commune. Studied mushrooms showed the interest quantity of selenium and L. cf cladodus had the highest concentration. Moderate selenium content of these wild mushrooms associated with their important antioxidant activities could provide health benefits to Bandundu’s populations in protecting against oxidative damage under different conditions including konzo.

＜正＞Now that the refurbishment of the Z machine at Sandia is complete we are routinely operating with currents over 26 MA into various *** routine operation we are able to measure current and voltage throughout the machine and compare with circuit code predictions. These measurements have motivated improvements to the original model to include two-dimensional （2D） and three-dimensional （3D） *** this paper we describe a full-machine （36 module）,one-dimensional （1D） circuit model of Z using the Bertha code developed at the Naval Research *** also describe a model that uses 2D *** addition,we discuss plans for implementing a 3D circuit model to allow investigating azimuthal effects that can be important for tailoring the rise time,shape,and length of the Z output *** tailoring on Z is achieved by staggering the timing of the various pulsed-forming modules,and by operating individual modules in either long or short-pulse *** the individual lines combine at a large diameter and are separated azimuthally, transit-time effects can be important for determining transient field enhancements at the vacuum insulator and in the vacuum transmission lines,as well as pulse "shape. Finally,we compare the 1D and 2D models with data, and provide predictions for both short and long pulse modes for various load configurations.

Introduction: Breast cancer in women is a global scourge due to its frequency and high fatality rate. If screening has made it possible to considerably reduce its incidence and its mortality in developed countries, in our developing countries, it remains frequent with a still high mortality due to ignorance, late and non-systematized screening. Research Question: Can female health caregivers be incorporated into a breast cancer screening awareness team? Objective: It aimed at evaluating the knowledge of female health caregivers in Douala hospitals, added to that of female users on breast cancer screening for their efficient operationalization in this procedure. Methodology: This was a comparative cross-sectional study for analytical purposes for a period of 07 months from January 15 to July 15, 2020 conducted by means of a structured and pre-tested questionnaire after informed consent obtained from the participants received in the consultation units of these hospitals. The study variables were socio-demographic and cognitive. The data collected were entered and analyzed using SPSS 23.0 software (statistical package for social sciences) with a significance level established for a value of p Results: We retained 1000 women fulfilling our inclusion criteria, including 818 users and 182 health caregivers, i.e. an average ratio of 4 users for 1 caregiver. The average age of the users was 31.03 ± 11.31 years and that of the caregiver was 29.54 ± 8.14 years (with extremes of 15 and 67 years identical in the two groups) with a respective median of 29 and 28 years old. Good knowledge was significantly associated with level of education (secondary OR = 0.38, p = 0.03 and University OR = 0.22, p = 0.001) with a predominance of good knowledge among care givers (83.5%) against 56.2% among users. The association between caregiver and good knowledge appeared to be statistically significant (OR = 0.25;p < 0.0001). In general, the association of users and poor knowledge carried a 4

本文描述了一个用于开发腐植酸(HAs)三维结构模型的完整的实验和计算框架。这种方法结合了实验表征、计算机辅助结构解析(CASE)和原子模拟,生成与HAs的分析数据和热力学/结构特性相一致的所有三维结构模型或这些模型的代表性样本。从元素分析、漫反射傅里叶变换红外光谱、一维/二维~1H和C溶液核磁共振光谱和电喷雾电离四极杆飞行时间质谱(ESI QqTOF MS)中获得的结构数据,结合CASE程序SIGNATURE,生成了切尔西土壤腐植酸(HA)所有的三维结构模型。这些模型随后被用作初始三维结构,进行恒温恒压分子动力学模拟,以估算其体密度和Hildebrand溶解度参数。只有少数模型异构体显示出的分子组成和体热力学性质与实验数据一致。这些模型异构体的等摩尔混合物的模拟C核磁共振光谱与切尔西土壤HA的实测光谱相比有较好的一致性。
