This article presents the results of the quantitative determination of fatty acids and vitamins, contained in Acanthophyllum pungens plants, belonging to the Caryophyllaceae family growing in Khantagi, located near the city of Kentau, Turkestan region. As a result of gas chromatography of fatty acids, obtained as a result of studies of plant materials, it has been found that Acanthophyllum pungens contains 87% of unsaturated fatty acids, and 13% of saturated fatty acids. Saturated fatty acids: myristic, palmitic, stearic, pentadecanoic acids, while unsaturated fatty acids: palmitic, oleic, linoleic, and linolenic acids. As a result of quantitative analysis, it has turned out that oleic and linoleic acids are contained in large quantities, and the content of linolenic acid is much lower. It has been established that the plant Acanthophyllum pungens contains water-soluble B3-nicotinic acid, B5-pantothenic acid, B9-folic acid and vitamins A, C, E. It has also been found that the relatively high content of vitamin B5 (pantothenic acid), and the content of vitamins B6, B1, B2 and D are absent altogether. The phytochemical studies of the aboveground part of the Acanthophyllum pungens plant collected during the budding phase have been carried out in accordance with the methodological recommendations of the State Pharmacopoeia of the Republic of Kazakhstan. Using Clarus-600 gas chromatography, the amount of fatty acids (high-carbon acids) contained in the Acanthophyllum pungens plant has been determined. A qualitative analysis has been carried out by paper chromatography (PC) and gas-liquid chromatography (GC). A certain amount of vitamins and fatty acids of the Acanthophyllum pungens plant has been recommended for the first time.

Human economic activity leads to removal of nutrients from the soil along with the crop. Nutrients losses also occur because of natural processes (erosion, leaching, etc.). It is necessary to replenish the missing nutrients with the use of humate-containing organomineral fertilizers to preserve soil fertility and increase productivity. The purpose of this work is to study the processes of iron (III) phosphates interaction with potassium humate and to obtain humate-containing organomineral fertilizers. Methodology. Chemical analysis, infrared spectroscopy, X-ray phase analysis methods have been used. Results and discussion. The processes of obtaining humate-containing organomineral fertilizers by the interaction in the systems “iron dihydrogen phosphate - potassium humate”, “iron hydrogen phosphate - potassium humate” and “iron orthophosphate - potassium humate” have been studied. It has been determined that an increase in the S:L ratio from 1:3 to 1:6 leads to an increase in the content of the digestible forms of Р2О5 up to 44.70%, nitrogen up to 1.85% and the output of humic substances up to 79.23%. An analysis of the IRS data indicates the multicomponentness and complexity of the composition of humate-containing organomineral fertilizers samples. Conclusion. It has been shown that the absorption bands of humic compounds of various functional groups and various substitutions phosphates are superimposed, while the shape of the absorption bands distorted, and their maxima have shifted to the high- or low-frequency area. It has been found that, regardless the phosphate ionnature, an increase in the ratio of S:L leads to a decrease in the absolute content of total, water-soluble and assimilable forms of P2O5. Concurrently, the phosphate part almost completely converted into the assimilated form. It has been defined that adding of the potassium humate, makes all phosphorus, which is in the indigestible form in the iron phosphates, almost completely pass into a mobile and assimilable form. It has been revealed that the addition of potassium humate into the systems with iron phosphates of various degrees of substitution makes it possible to neutralize the residual acidity of the pulp, and the neutralization process proceeds without P2O5 retrogradation. The resulting products have good physical, mechanical and fertilizer properties.
Domestic water quality and the discriminatory influence of socio-economic stratification on accessibility to safe water in a part of Osun State, Nigeria
Authors: ELUDOYİN Adebayo
Published: June 2023

The status of the water supplied to households in an urban local government area in southwest Nigeria was examined. Specific objectives were to characterize household water sources, assess the per capita usage of potable water sources and examine quality of the household water in the area. The purposively selected study area, Olorunda local government area in Osun State, Nigeria (being an urban local government area) was stratified into ‘urban core’ (central business district, CBD or high population density area), ‘transition’ (medium population density area but with less social infrastructure) and ‘sub-urban’ (typically government reserved area and low population density area) based on household density and associative socio-economic status. The methods were a mix of questionnaire administration to heads of 120 households (40 per stratum) and collection of the drinking water samples from the supply sources at four randomly selected households in each stratum. The water samples were analysed for the concentrations of nitrite (NO2-), nitrate (NO3-), fluoride (F-), lead (Pb) and arsenic (As) as well as E-coli bacteria contents based on their importance in determining water quality in urban areas. The results showed that domestic water sources are mainly hand dug well (55.8%), borehole (37.5%) and pipe borne (6.7%). Residents averagely consumed at most 4L of water per day. Furthermore, the investigated chemical parameters varied as NO2 (0.37-0.94 mg/l), NO3 (0.29-0.70 mg/l), and F- (0.003-0.97 mg/l). As and Pb occurred in trace quantities, and there were no pollution threats to consumers. The amount of E coli and total coliform contents were however outside the safe limits for residents, suggesting contamination of household water by the bacteria sources. The study concluded communities with low socio-economic status which do not have access to state-provided tap water source are more likely to consume polluted water than those with high socio-economic status or that are supplied with state-provided tap water. The study advocates improve urban water management for the urban fringe dwellers.

Abstract. The oxidation of sabinene by the hydroxyl radical (OH) and ozone (O3) was investigated under atmospherically relevant conditions in the atmospheric simulation chamber SAPHIR at Forschungszentrum Jülich, Germany. The rate constants of the reactions of sabinene with OH and with O3 were determined. The temperature dependence between 284 K to 340 K of the rate constant of the reaction of sabinene with OH, kSAB+OH, was measured for the first time using an OH reactivity instrument, resulting in an Arrhenius expression of (1.67 ± 0.16) × 10−11 × exp((575 ± 30) T−1) cm3 s−1. The values agree with those determined in chamber experiments in this work and reported in the literature for ~298 K within the uncertainties of measurements. The ozonolysis reaction rate constant of sabinene (kSAB+O3) determined in chamber experiments at a temperature of (278 ± 2) K is (3.7 ± 0.5) × 10−17 cm3 s−1, which is 55 % lower than the value reported in the literature for room temperature. The measurement of products from the oxidation of sabinene by OH resulted in an acetone yield of (21 ± 15) %, a formaldehyde yield of (46 ± 25) %, and a sabinaketone yield of (19 ± 16) %. All yields determined in the chamber experiments agree well with values from previous laboratory studies within their uncertainties. In addition, the formaldehyde yield determined in this study is consistent with that predicted by the sabinene OH-oxidation mechanism which was devised from quantum chemical calculations by Wang and Wang (2018), whereas the acetone yield is about 15 % absolute higher than that predicted by the mechanism. In the ozonolysis experiments, the analysis if product measurements results in an acetone yield of (5 ± 2) %, a formaldehyde yield of (48 ± 15) %, a sabinaketone yield of (31 ± 15) %, and an OH radical yield of (18 ± 25) %. The OH radical yield is lower than expected from the theoretical mechanism in Wang and Wang (2017), but the value still agrees within the uncertainty. An analysis of the chemical budget of OH radicals was performed for the chamber experiments. The analysis reveals that the destruction rate of OH radcials matches the production rate of OH suggesting that there is no significant missing OH source for example from isomerization reactions of peroxy radicals for the experimental conditions in this work.
Improved estimates of smoke exposure during Australia fire seasons: Importance of quantifying plume injection heights

Abstract. Wildfires can have a significant impact on air quality in Australia during severe burning seasons, but incomplete knowledge of the injection heights of smoke plumes poses a challenge for quantifying smoke exposure. In this study, we use two approaches to quantify the fractions of fire emissions injected above the planetary boundary layer (PBL), and we further investigate the impact of plume injection fractions on daily mean surface concentrations of fine particulate matter (PM2.5) from wildfire smoke in key cities over northern and southeastern Australia from 2009 to 2020. For the first method, we rely on climatological, monthly mean vertical profiles of smoke emissions from the Integrated Monitoring and Modelling System for wildland fires (IS4FIRES), together with assimilated PBL heights from NASA Modern-Era Retrospective analysis for Research and Application (MERRA) version 2. For the second method, we develop a novel approach based on the Multi-angle Imaging Spectro-Radiometer (MISR) observations and a random forest, machine-learning model that allows us to directly predict the daily plume injection fractions above the PBL in each grid cell. We apply the resulting plume injection fractions quantified by the two methods to smoke PM2.5 concentrations simulated by the Stochastic Time-Inverted Lagrangian Transport (STILT) model in target cities. We find that characterization of the plume injection heights greatly affects estimates of surface daily smoke PM2.5, especially during severe wildfire seasons, when intense heat from fires can loft smoke high in the troposphere. However, using climatological injection profiles cannot capture well the spatiotemporal variability of plume injection fractions, resulting in a 63 % underestimate of daily fire emission fluxes injected above the PBL. Our random forest model successfully reproduces the daily injected fire emission fluxes against MISR observations (R2 = 0.88, normalized mean bias = 10 %), which predicts that 27 % and 45 % of total fire emissions rise above the PBL in northern and southeastern Australia, respectively, from 2009 to 2020. Using the plume behavior predicted by the random forest method also leads to the best model agreement with observed surface PM2.5 in several key cities, with smoke PM2.5 accounting for 5 % to 52 % of total PM2.5 during fire seasons from 2009 to 2020.
Existence and influence of mixed states in a model of vegetation patterns
Authors: Vanderveken Lilian , Martínez Montero Marina , Crucifix Michel
Published: June 2023

Abstract. The Rietkerk vegetation model is a system of partial differential equations, which has been used to understand the formation and dynamics of spatial patterns in vegetation ecosystems, including desertification and biodiversity loss. Here, we provide an in-depth bifurcation analysis of the vegetation patterns produced by Rietkerk's model, based on a linear stability analysis of the homogeneous equilibrium of the system. Specifically, using a continuation method based on the Newton-Raphson algorithm, we obtain all the main heterogeneous solutions for a given size of the domain. We confirm that inhomogeneous vegetated states can exist and be stable, even for a value of rainfall for which no vegetation exists in the non-spatialized system. In addition, we evidence the existence of a new type of solution, which we called "mixed state", in which the equilibria are always unstable and take the form of a mix of two solutions from the main branches. Although these equilibria are unstable, they influence the dynamics of the transitions between distinct stable states, by slowing down the evolution of the system when it passes close to it. Our approach proves to be a helpful way to assess the existence of tipping points in spatially extended systems and disentangle the fate of the system in the Busse balloon. Overall, our findings represent a significant step forward in understanding the behavior of the Rietkerk model and the broader dynamics of vegetation patterns.
Downscaling of surface wind forecasts using convolutional neural networks
Authors: Dupuy Florian , Durand Pierre , Hedde Thierry
Published: June 2023

Abstract. Near-surface winds over complex terrain generally feature a large variability at the local scale. Forecasting these winds requires high-resolution Numerical Weather Prediction (NWP) models, which drastically increases the duration of simulations and hinders to run them on a routine basis. Nevertheless, downscaling methods can help forecasting such wind flows at limited numerical cost. In this study, we present a statistical downscaling of WRF wind forecasts over south-eastern France (including the south-western part of the Alps) from its original 9-km resolution onto a 1-km resolution grid (1-km NWP model outputs are used to fit our statistical models). Downscaling is performed using convolutional neural networks (CNNs), which are the most powerful machine learning tool for processing images or any kind of gridded data, as demonstrated by recent studies dealing with wind forecasts downscaling. The previous studies mostly focused on testing new model architectures. In this study, we aimed to extend these works by exploring different output variables and their associated loss function. We found that there is no one approach that outperforms the others on both the direction and the speed at the same time. Finally, the best overall performance is obtained by combining two CNNs, one dedicated to the direction forecast, based on the calculation of the normalized wind components using a customized mean squared error (MSE) loss function, and the other dedicated to the speed forecast, based on the calculation of the wind components and using another customized MSE loss function. Local-scale, topography-related wind features, which were poorly forecast at 9 km, are now well reproduced, both for speed (e.g. acceleration on the ridge, leeward deceleration, sheltering in valleys) and direction (deflection, valley channeling). There is a general improvement in the forecast, especially during the nighttime stable stratification period, which is the most difficult period to forecast. It results that, after downscaling, the wind speed bias and MAE are reduced from −0.55 m⋅s−1 and 1.02 m⋅s−1 initially to −0.01 m⋅s−1 and 0.69 m⋅s−1 respectively, while the wind direction MAE is reduced from 25.9° to 15.5° in comparison with the 9-km resolution forecast.

Authors: Asmat Ullah Durrani, Manzoor Ahmed
Published: June 2023

Indo-Pak relations throughout the seventy-five years of co-existence have been no less than a roller coaster ride. Scholars have attributed this peculiar and toxic romance to various factors among them Kashmir stands out in it being the jugular vein of Pakistan as all three western rivers, on which Pakistan’s agriculture sector solely depends, flow from the Indian administered Kashmir. India is using this to their advantage by planning to construct hydropower dams on the western river, likely affect Pakistan’s agriculture sector, all while publically proclaiming “Blood and water cannot flow together” Countries around the world have started introducing Agtech like Water Conserving Technologies (WCTs) in their agriculture sector in the face of growing water demand and water security. These WCTs not only use less water but also increase the overall yield of the crop. This study is an interdisciplinary endeavour which intends to link the impact of introduction of WCTs in the agriculture sector with the Indo-Pak relations in the context of Kashmir. The Secondary data was collected by searching through key words and reviewing the literature and was analysed through meta-analysis. The study concludes that introduction of AgTech in the agriculture sector of Pakistan has the potential to bring India and Pakistan closer in the context of Kashmir

This article contains ideas about the importance of visual language development for architecture students. Our field of research falls into the issue of methodological approaches with an emphasis on the development of visual language within specialized disciplines, complemented by a complex system of extracurricular activities. We support the idea that the specific methods of aesthetic education must be actively applied in the development of visual language, having great value in the aesthetic and professional training of architecture students. The present study aims to synthesize the results of some investigations carried out in this problematic area, determining the theoretical and methodological foundations for the development of the visual language of architectural students from the perspective of aesthetic values.

Published: June 2023

Este trabalho intitulado “Os significados da utilização dos recursos didáticos no processo de ensino aprendizagem da Sociologia”, teve como objetivo geral compreender os significados da utilização de recursos didáticos para o ensino de Sociologia. Para tanto, realizou-se uma pesquisa exploratória, com abordagem qualitativa na Escola Estadual “Monteiro”, tendo como instrumentos de coleta de dados um questionário com nove (09) questões, sendo oito abertas (objetivas) e uma (01) fechada (subjetiva) que foi aplicado a sessenta alunos, distribuídos nas turmas do 1º, 2º e 3º Ano do Ensino Médio, e a entrevista semiestruturada com dezesseis (16) questões abertas (subjetivas) que foram destinadas a duas (02) professoras que lecionam a referida disciplina. Após a coleta dos dados, os mesmos foram encaminhados para o cumprimento da etapa de caracterização e análise qualitativa dos resultados obtidos. Assim, os resultados analisados demonstraram que embora os recursos didáticos sejam compreendidos como sendo instrumentos facilitadores do processo de ensino/aprendizagem, os mesmos não são utilizados de forma diversificada e com frequência pelas docentes, que ainda continuam a utilizar os recursos considerados tradicionais, como o quadro negro e o livro didático.

Published: June 2023

Com o surgimento da tecnologia digital no decorrer das últimas décadas parte da sociedade tem experimentado inovadoras formas de socialização, tanto no âmbito regional como global, estas formas de socialização influenciam diversas facetas da vida cotidiana principalmente na formação identitária dos indivíduos envolvidos. Nosso trabalho tem como objetivo analisar os processos de formação identitária e consequentemente as ações sociabilizantes dos indivíduos, estes estabelecem conexões nas ambiências online gerando constructos identitários: os personagens. Esta pesquisa de abordagem qualitativa, do tipo participativa, com utilização de técnica de entrevista e observação participante. Para o nosso ambiente de estudo utilizamos o jogo Brasil Ragnarok Online, por meio de vinte e seis entrevistas com os jogadores, além, da observação participante, este modelo nos possibilitou interagir ativamente dentro dos processo ingame. Os dados da pesquisa nos mostram que os jogadores estabelecem zonas de sociabilização, onde o contato entre os participantes é pautado em um primeiro momento pelas necessidades dentro do jogo, modificando-se posteriormente para um modelo de grupamentos sociais onde estes contatos entre os jogadores fomentam relações mais duradoras que se estendem para fora dos espaços do jogo, para tanto este estudo contribuiu na criação de suas teorias, o paradoxo da escolha dirigida e os ciclos de imersão ciberlúdicos, o primeiro articula-se com as escolhas apresentadas pelos desenvolvedores do jogo para os jogadores e as modificações criadas pelos próprios jogadores, a segunda serve como mapeamento dos estágio ingame e as sociolizações inerentes a este jogo em especial. Nesta perspectiva desenvolvemos elementos que podem auxiliar de forma direta ou indireta os estudos futuros, e fomentar outras pesquisas no âmbito a promover maiores desenvolvimentos nesta área do conhecimento antropológico e social nas redes digitais.

As empresas buscam a cada dia produzir produtos com maior qualidade, entretanto, com menor perda possível de tempo, recursos e custos. Dessa forma, o controle estatístico do processo surge como uma ferramenta importante para o controle de processo, que analisa e interpreta dados com o intuito de, se necessário, indicar quando o processo precisa de melhorias. Diante do exposto, este trabalho tem com objetivo identificar as principais causas da variabilidade do peso do iogurte de morango 180g, a partir do uso de ferramentas de controle estatístico da qualidade. Foram elaborados o fluxograma e o histograma, que auxiliaram na descrição do processo onde se pôde observar que o processo era incapaz de produzir de acordo com os limites de especificação. Aplicando o gráfico de controle para o mês de agosto, verificou-se que existiam dois pontos em alerta, porém, para que estes dados sejam considerados como limites tentativos, ou seja limites em que o processo seja capaz de atender a especificação imposta ao longo dos meses analisados, o gráfico precisou ser recalculado, para isso retirou-se os pontos de alerta. Com isso, o gráfico ficou sob controle, atendendo as condições de limites de especificação, porém quando comparados com os limites dos meses de setembro alguns pontos saíram dos extremos. Já no mês de outubro verificaram-se vários pontos que se distanciavam cada vez mais destes limites, mesmo tendo sugerido novos limites tentativos para que o processo seja capaz de atender as especificações, isto não foi possível. Sugeriu-se novos limites de especificação para o processo e verificou-se que com eles o mesmo tornou-se capaz, para que isto seja possível é necessário a análise das causas especiais do processo, realizada através do uso de diagrama de causa e efeito, afim de elimina-las, tornando assim o processo sob controle.
