Vitrinite Paleogeothermics: Some Aspects Lajos Stegena
Authors: Estejena Lajos 
Published: July 2023

The method of determination of paleogeothermal conditions using vitrinite reflectance data, burial history and recent geothermics is reviewed. Proposals are given to improve this method. Improvements can be made in the measurement technique for vitrinite reflectance. For the calculation of TTI-s, it is suggested that the temperature interval in which the reaction rate of the maturation of organic matter doubles, depends on the temperature. A ∆T(T) function is proposed, which is based on the Arrhenius equation. For the calculation of theoretical R, values from the TTI-s, a TTI vs. Ro function is proposed. In the future, the application of monomolecular biomarker reaction (isomerization of sterane and hopane) may lead to more exact paleogeothermal determination. Neste trabalho é revisado o método de determinação das condições paleogeotermais usando dados de refletância da vitrinita, e de geotermia histórica e recente. São indicadas propostas para melhorar esse método. Melhorias podem ser introduzidas na técnica para medições da reflectância da vitrinita. Sugere-se que, para o cálculo Tempo/Temperatura (TTI) o intervalo de temperatura no qual dobrar a proporção de reação de maturação da matéria orgânica seja dependente da temperatura. A função ∆T(T) é proposta com base na equação de Arrhenius. Para o cálculo do valor de Ro a partir dos TTIs, a função TTI vs. Ro é proposta. A aplicação de reações mono-moleculares de "biomarcadores biológicos" (isomerização de estireno e hopano) poderá fornecer, no futuro, determinações paleo geotermais mais exatas.

Published: July 2023

Background and Purpose: With fund scarcity eminent in Malaysia, soliciting donations effectively is essential to any non-profit organisation (NPO). Many NPOs struggle to raise funds to execute a beneficial project for society. The dimensions to identify relevant online factors influencing the NPO website user decision-making process slowly evolved in a local context due to limited interest in exploring this field. This research was conducted to identify relevant variables related to NPO website user interest to donate. However, a proper instrument must be developed to meet the research aim. Thus, this research was conducted to identify relevant variables and items in the research instrument.

Methodology: The study collected 269 responses from ten popular NPO website users. Their responses were recorded using the five-point Likert Scale questionnaire ranging from strongly agree to strongly disagree. At first, the study conducted a content validity test and a pre-test. The sample size is determined based on the SEM requirement. Finally, the responses are analysed using pooled confirmatory factor analysis to determine the instrument reliability and validity.

Findings: Only seven variables are retained after the validity and reliability analysis, with 43 items out of 74 items. The result indicated only information, system, service quality, perceived ease of use, and trust are relevant for the NPO to meet website user satisfaction and influence their decision to donate.

Contributions: The finding is essential as a guideline to develop a website that meets user preferences. The result also contributed to the website quality literature for the non-profit sector.

Keywords: Website quality, trust, satisfaction, non-profit organisation, technology acceptance model.

Abstract
The free-range system improves chicken’s welfare and enriches their diet. There is little information about influence of chickens on the sward quality. The aim of the study was to identify differences in the chemical and botanical composition of the pasture sward used by chickens and to assess if frequency of chicken exits outdoors is associated with the botanical composition of the ranging areas. One hundred twenty non-beak trimmed mixed sex birds of Green-legged Partridge (GP) and Sasso line C44 (S) were used. Each pen had direct access to an individual outdoor range providing 10.5 m2 per chicken, video-recorded continuously. Vegetation coverage regarding botanical composition was determined based on botanical-weight analysis from three control plots, while range use was calculated from the video material. The data were analysed by ANOVA model in SAS software (v 9.4). Regarding chemical composition, fiber content was higher in dry matter from the control pastures. Significantly more Dactylis glomerata (L.) and Alopecurus pratensis (L.) were observed on ranges used by Sasso. The higher share (%) of weeds and grasses was at the ranges used by chickens (weeds: S:8.66 (1.42) and GP:7.61 (0.59) and grasses: S:10.36 (0.96) and GP:12.10 (0.65)) as compared to control plots (1.45 (1.34)) and 3.86 (2.97), respectively) in contrast to legumes ((S:0.01 (0.01) and GP:0.32(0.26)) and sedges (S:0.64 (0.48) and GP: 0.09 (0.06)) most present in the control plots (10.88 (1.55)). Positive association between range use frequency and proportion of Heracleum sphondylium (L.), Rumex acetosa (L.), Festuca rubra (L.), and Lolium perenne (L.) was observed for Sasso, while foe Green-legged Partridges with proportion of Armoracia rusticana (L.), Stellaria media (L.), Ranunculus repens (L.), Cirsium arvense (L.) and Rumex crispus (L.). Concluding, the sward quality of the ranging areas was affected by the presence of the chickens and it differed between genotypes. Unknown remain if birds used the pasture more frequently depending on its botanical composition or if the pasture composition depended on the frequency of its uses by the birds.

AbstractUnderstanding the variables that determine the variation in forest species composition and diversity in tropical montane systems remains a topic for discussion in plant ecology. This is especially true in areas where the topography is complex and forests are vulnerable to human activity. In this study, a set of topographic, soil, and climatic variables were used to determine their effects on the composition and diversity patterns of two forests in the West Usambara Mountains (Tanzania). Two-phase systematic sampling was used to collect vegetation data from 159 sample plots distributed across the forests. An agglomerative hierarchical clustering method was used for forest community classification, and indicator species analysis was used to determine the species significantly associated with forest communities. The influence of environmental variables on forest communities was analysed using canonical correspondence analysis (CCA). Finally, we evaluated diversity patterns by comparing diversity indices (Shannon-Wiener diversity index, evenness, and richness) and beta diversity processes. In total, 7,767 individual trees belonged to 183 species, 132 genera, and 66 families were quantified. We found that (i) the forests of West Usambara can be divided into three different forest communities; (ii) each forest community has a specific set of topographical, soil, and climate variables; (iii) there are significant differences in Shannon diversity and richness indices among communities; and (iv) community composition is mostly influenced by species turnover than by species nestedness. Our study revealed the importance of considering a set of environmental variables related to climate, soil, and topography to understand the variation in the composition and diversity of forest communities in tropical montane forests.

Published: July 2023

Abstract
Forest fires are among the most significant disturbances on a global scale. Affecting biodiversity and biogeochemical cycles, forest fires play an important role in atmospheric chemical processes and the global carbon cycle. Using the example of the pyrogenic landscapes of the Samara region, this article reviews changes in the accumulation regularity of heavy metal content and its migration within a soil profile during pyrogenic soil formation. In the case of surface forest fires, the studied postpyrogenic soils are characterized by increased cadmium, nickel and zinc content in the Opyr pyrogenic horizon. In contrast, the content of all analyzed heavy metals decreases compared to the control for crown forest fires, indicating active element emissions into the atmosphere.

Для сохранения качества продуктов при быстром охлаждении или для обеспечения их длитель- ноготермостабильного хранения необходимо обладать научно обоснованным прогнозным аппаратом по раз- витию кинетики тепловойобработки этих субстанций. В качестве одного из перспективных путей обеспе- чения безопасности, сохранения качества и увеличения срока годности (хранения) пищевых продуктов при минимальной переработке сырья является технологический процесс холодильной обработки на базе охлаждения, обеспечивающего понижение температуры (на 1–2°C) ниже криоскопического значения.Практическая реали- зация такой технологии предотвращает развитие в пищевых продуктах крайне нежелательных необратимых из- менений – явлений кристаллообразования в биологических структурах. На основе базирующегося на законе со- хранения энергии уравнения теплопроводности и концепции передачи тепла вследствие фазового перехода на фронте замерзания обоснован расчет и проведено численное и экспериментальное исследование протекания про- цесса охлаждения по времени стратификации температурыпо толщине продукта в форме пластины. Установ- лено качественное и количественное согласие теоретических и опытных результатов исследуемого процесса.
In order to preserve the quality of products during rapid cooling or to ensure their long-term thermostable storage, it is necessary to havea scientifically based predictive apparatus for the development of the kinetics of heat treatment of these substances. As one of the promising ways toensure the safety, preservation of quality and increase the shelf life (storage) of food products with minimal processing of raw materials is thetechnological process of refrigeration based on cooling, which provides a decrease in temperature (1–2°C) below the cryoscopic value. The practicalimplementation of such technology prevents the development of extremely undesirable irreversible changes in food products – the phenomena ofcrystal formation in biological structures. On the basis of the heat conduction equation based on the law of conservation of energy and the concept of heat transfer due to the phase transition at the freezing front the calculation is justified and numerical and experimental investigation of the coolingprocess is carried out by the time of temperature stratification along the thickness of the product in the form of a plate. The qualitative and quantitativeagreement of the theoretical and experimental results of the process under study has been established.
