Abstract:

Elemental analysis is a fundamental method for determining the carbon, hydrogen, nitrogen, sulphur, and oxygen (CHNSO) contents in organic materials. Automated conventional elemental analysers are commonly used for CHNSO determinations, but they face challenges when analysing volatile organic liquids due to sample losses. This present study explores the combination of gas chromatography–mass spectrometry (GC/MS) and gas chromatography–flame ionisation detection (GC/FID) as a more accurate alternative method for elemental analysis of such liquids. Six different liquid samples containing various

Grinding of straw contributed to the maximum increase in the biomethane potential. Only Fenton or only the autoclave process improves the kinetics slightly but does not considerably improve the biomethane potential. Combining autoclaving a

Authors investigated the catecholaminergic neurotransmitters (chNs) quantitative modifications in pregnant uterine Lower Uterine Segment (LUS) during prolonged labor (PL) with the fetus in an occiput-posterior position (OPP), in occiput transverse position (OTP) and in fetal head asynclitism, all diagnosed by Intrapartum Ultrasonography (IU). The chNs neurotransmitters, particularly adrenaline (or epinephrine-A) and noradrenaline (or norepinephrine-N), were evaluated in LUS fragments sampled during CS of 34 patients undergoing urgent cesarean section (CS) in PL, compared to chNs fibers in the

Abstract:

Introduction: Evidence supporting successful task sharing to increase Intrauterine Contraceptive Device (IUD) uptake exist in some developing countries that have challenges with availability of trained health professionals. Although Community Health Nurses (CHNs) in Ghana are trained to provide primary health care including emergency deliveries in rural communities, they are not professionally mandated to provide IUD services.Objectives: To explore stakeholders’ views on task sharing IUD services with CHNs in Ghana.Methods: This qualitative case study was conducted in Accra, Ghana between June

Abstract:

Using the China Health and Nutrition Survey (CHNS), this paper analyses that height for age (HAZ) of children from urban area is higher than that of those from rural areas on average and the height varies among rural children. Gender also has similar impact on children’s height, namely, HAZ of girls is lower than that of boys. In addition, only children has better nutrition health than others and living with parents or not has great impact on children’s nutrition health as well.

Abstract:

Purification on kappa (ƙ) carrageenan was performed by dissolving ƙ-carrageenan powder in distilled water and re-precipitated with ethanol and n-hexane separately during re-precipitation process. The purified kappa carrageenan was analyzed by using Fourier transform infrared (FTIR) spectroscopy and carbon, hydrogen, nitrogen, and sulfur (CHNS) elemental analysis. The outcomes from FTIR showed there are physical changes due to intermolecular interactions which lead to decrease and lower intensity of hydroxyl band at 3345 cm-1 after re-precipitated with n-hexane, compared to re-precipitation wit

Abstract:

Community empowerment has been studied as a process and result phenomenon throughout the last 40 years. Community partnership, which has been studied during the last 20 years, has been identified as a key process to promote intervention and research within communities. In this paper, we introduce the relation between these two concepts, from the research that is being developed at the Centre for Interdisciplinary Health Research (CIIS) in Universidade Católica Portuguesa. We comment on the available evidence regarding community partnership and community empowerment within the Nursing Decision-

Abstract:

The most important asset for a person is their health and wellbeing. While it is possible to keep one’s health at its best, it is common for people to have health shocks (HSs; negative shocks to an individual’s health). In this study, using Chinese Health and Nutrition Survey (CHNS) panel data, we studied the impact of different HSs on income using new modified methods. Thus, we considered the substantial links among different HSs, levels of education, and insurance types, as well as their impact on people’s wealth defined by their income. The core aim of this study is to help devise and guide

Abstract:

Forests in Portugal are highly dependent on a short number of wood species, and new species with higher profitability are needed. The Paulownia species has generated great interest due to its fast-growing and relatively good wood properties. However, environmental factors have shown that Paulownia grows differently in each case. This study intends to determine the properties of young Paulownia trees from Portuguese plantations to determine the best age to cut the trees according to their use.

Szerokie spektrum dostępnych technik analitycznych powoduje, że można oznaczyć bardzo wiele pierwiastków. Dużą popularnością cieszą się analizatory elementarne CHNS, w różnej konfiguracji, w których dokonuje się analizy kilku wybranych pierwiastków w zależności od potrzeb danego laboratorium. W laboratorium Geochemii Nafty i Gazu bada się różne próbki pod kątem analizy elementarnej. Są to przede wszystkim skały, kerogen oraz ropy. Wyzwaniem jest ozn
