Milk production continues to be the main source of income for dairy producers, and mastitis continues to be the major health challenge for dairy cows worldwide. The objective of the current study was to describe the different management practices implemented in Egyptian dairies, which may influence mastitis and improve milk quality. An in-person survey was completed with herd managers and owners of 20 Egyptian dairies selected using a stratified random sample from four of Egypt’s milk sheds. The questionnaire included 80 questions that inquired about herd demographics, mastitis status and control, milking practices, and management practices of the study dairies. Statistical analyses included descriptive statistics, multiple factor analysis (MFA), and hierarchical clustering to identify the important principal components and different dairy clusters. Of the surveyed herds, 69.50% had less than 500 lactating cows, with Holstein as the main cow breed. The reported average milk production on the study herds was 31.1 (SE ± 1.10) Kg/cow/day. Housing of lactating, dry, and close-up cows was in open lots. The majority of the dairies milked cows were three times per day (90.63%), the remaining milked cows four (5.00%) or a mix of four and three times per day. Furthermore, herringbone parlor design was the most common parlor design (66.79%) in the study dairies. The most common disinfectants used for both pre- and post-milking teat dip were iodine-based, 90.0% and 95.0%, respectively, while 52.16% of the dairies reported that their milkers wore gloves during milking. The reported mean annual percentage of mastitis was 52.3%, as a percent of the milking herd. The study dairies reported the inspection of udder health through either visual inspection (95.00%), udder hygiene score (86.88%), teat end score (71.88%), and/or using CMT (54.91%). Contagious mastitis pathogens were reported in 45.2% of the study herds. More than 50% of the study herds relied on importing pregnant cows or pregnant heifers as replacements. Multiple factor analysis identified 20 questions and represented 5 components of variability related to mastitis on dairies. The current survey of Egyptian dairies described the herd demographics and different management practices related to mastitis control and prevention. All the study dairies relied on the blanket intramammary antimicrobial drugs at dry off when current research elsewhere has identified selective dry cow therapy as an integral component of antimicrobial stewardship on dairies. Further research is required to identify the association between different management factors and the occurrence of mastitis.

Brewer’s spent grains (BSG) are a significant by-product of beer production, and its improper disposal poses environmental challenges. This study investigated the use of BSG for activated carbon production with phosphoric acid as a chemical activator and its application in cheese whey remediation through liquid-phase adsorption. The adsorbent was thoroughly characterized through using techniques such as FTIR, SEM, N2 isotherms, and surface charge distribution. The adsorbent exhibited substantial pores, a high surface area (605.1 m2 g–1), good porosity, and positive surface charges that facilitated favorable interactions with cheese whey compounds. Equilibrium was achieved in 330 min for lactose, BOD5, and COD. The maximum adsorption capacities were 12.77 g g–1 for lactose, 3940.99 mg O2 g–1 for BOD5, and 12,857.92 mg O2 g−1 for COD at 318 K. Removing these adsorbates from cheese whey effluent reduces its organic load, enabling water reuse in the manufacturing unit, depending on its intended use. The adsorption process was spontaneous and endothermic, with ΔH° ≥ 265.72 kJ mol−1. Additionally, the activated carbon produced demonstrated impressive regeneration capability with sodium hydroxide, maintaining 75% of its adsorption capacity. These results emphasize the potential of activated carbon as an effective adsorbent for cheese whey remediation, providing a sustainable solution for waste management in the dairy industry and water reuse.

Published: October 2023

A design flood is an essential input for water infrastructure design and flood protection. A flood frequency analysis has been traditionally performed under stationarity assumption indicating that the statistical properties of historical flooding will not change over time. Climate change and variability challenges the stationarity assumption, and a flood frequency analysis without consideration of non-stationarity can result in under- or overestimation of the design floods. In this study, non-stationarity of annual maximum floods (AMFs) was investigated through a methodology consisting of trend and change point tests, and non-stationary Generalized Extreme Value (NSGEV) models, and the methodology was applied to Campaspe River Basin as a case study. Statistically significant decreasing trends in AMFs were detected for almost all stations at the 0.01 significance level in Campaspe River Basin. NSGEV models outperformed the stationary counterparts (SGEV) for some stations based on statistical methods (i.e., Akaike information criterion (AIC) and Bayesian information criterion (BIC)) and graphical approaches (i.e., probability and quantile plots). For example, at Station 406235, AIC and BIC values were found to be 334 and 339, respectively, for the SGEV model, whereas AIC and BIC values were calculated as 330 and 334, respectively, for the NSGEV 15 model with time-varying location and scale parameters. Deriving a design flood from conventional stationary models will result in uneconomical water infrastructure design and poor water resource planning and management in the study basin.

Combined with visible light remote sensing technology and InSAR technology, this study employed the fundamental principles of the frequency ratio model, information content model, and analytic hierarchy process to assess the susceptibility of the study area. Nine susceptibility assessment factors such as elevation, slope, aspect, water system, vegetation coverage, geological structure, stratum lithology, rainfall, and human activities were selected, and the factor correlation degree was calculated by using the relative area density value of the landslide. The frequency ratio model and information content model were selected to carry out landslide susceptibility zoning, and the accuracy of the two models was verified by the ROC curve and density method. The results indicate that the information content model performed relatively well. Therefore, the information model, combined with the analytic hierarchy process and fuzzy superposition method using the landslide point density map, was chosen to evaluate landslide susceptibility. The study area was divided into five levels of landslide hazard, ranging from low to high, using the natural discontinuity point method. The results show that the area of each hazard zoning is 197.48, 455.72, 408.21, 152.66, and 16.22 km2 from low to high, and the proportion of landslides in the corresponding area is 0.17%, 1.60%, 3.88%, 8.41%, and 16.65%, respectively. It can be seen that with the increase in the hazard level, the proportion of landslides also increases significantly, which verifies the accuracy of the hazard results. Additionally, four representative landslides in the study area were selected for analysis to understand their characteristics and underlying mechanisms. The results revealed that these landslides were notably influenced by the density of the Jinsha River and the surrounding roads. The susceptibility assessment outcomes for geological disasters align well with the current situation of landslide occurrences in the Tuoding river section, demonstrating high accuracy. This study provides a scientific foundation for effective prevention and control measures against local landslide disasters.

The biological reduction of Fe (III) is common in underground environments. This process not only affects the biogeochemical cycle of iron but also influences the migration and transformation of pollutants. Humic substances are considered effective strategies for improving the migration and transformation of toxic substances and enhancing the bioavailability of Fe (III). In this study, the electron shuttle anthraquinone-2-sulfonate (AQS) significantly promoted the bio-reduction of Fe (III). On this basis, different concentrations of aniline were added. The research results indicate that at an aniline concentration of 3 μM, the production of Fe (II) in the reaction system was 2.51 times higher compared to the microbial reaction group alone. Furthermore, the degradation of aniline was most effective in this group. The increased consumption of sodium lactate suggests that aniline, under the mediation of AQS, promoted the metabolism of Shewanella oneidensis MR-1 cells and facilitated the involvement of more electrons in the reduction process. After the reaction, the solid mineral Fe (II)-O content increased to 41.32%. This study provides insights into the reduction mechanism of Fe (III) in the complex environment of microorganisms, iron minerals, electron shuttles, and pollutants. It aims to offer a theoretical basis for the biodegradation of aromatic hydrocarbon pollutants.

Tuberculosis (TB) is a major public healthcare problem. The fight against the disease is complicated due to the growing emergence of drug-resistant forms, the treatment of which can be quite difficult. Extrapleural pneumonolysis (EPP) with plombage was widely used to treat cavitary pulmonary tuberculosis in the late 1950s. The EPP surgical method is characterized by the creation of extrapleural space and its filling with plastic material to achieve long-term collapse. Plombage included a number of materials, such as fat, paraffin wax, bone, sponge, gelatin, silicone, methyl methacrylate (Lucite) or polyethylene balls. However, the presence of foreign structures for a long period of time can lead to complications in the form of malignant tumors, erosion of small and large vessels with bleeding, and migration of plombage material. In recent decades, WHO has noted that surgical therapy may play an important role in TB treatment. Collapse surgery may be the only hope for patients who are not eligible for resection-type surgery. Currently, EPP is actively used in leading institutions to treat the most severe patients. This operation is indicated for patients with concomitant diseases, poor functional reserves of the body, as well as advanced tuberculosis, which does not allow resection of healthy lung tissue.

Displacement of the tracheostomy cannula (TSC) is a cause of morbidity and mortality in intensive care units. The analysis of Russian literature on the issue under study does not allow assessing the relevance and state of the problem in our country. The purpose of the study: to assess the relevance of the problem of TSC migration and the effectiveness of the implemented algorithm of actions in case of TSC displacement. The relevance was evaluated based on the results of a survey among resuscitators in the region. A retrospective single-center study was conducted in order to assess the effectiveness of the implementation of the algorithm of actions. The results obtained allow concluding that the problem of TSC migration is relevant for most resuscitators in the Stavropol Region. The development and application of a local algorithm of actions during the migration of the tracheostomy tube (TST) can reduce the frequency of errors in the provision of emergency care to this category of patients. Using the algorithm of actions during TST migration allows limiting the aggravation of the condition of patients who have undergone this critical episode.

Published: October 2023

O início da trajetória profissional docente é um momento decisivo, que envolve sentimentos como expectativas e inseguranças causadas pelo novo. A descoberta desse universo docente pode ser complexa, distinta do que os professores imaginavam quando ainda eram acadêmicos. O estudo possui como objetivo geral propor estratégias para o melhor acolhimento de professores iniciantes em um Centro de Estudo Tecnológico. A metodologia escolhida foi uma abordagem qualitativa. Esse artigo é parte de uma dissertação de mestrado na qual foram pesquisadas duas escolas de nível médio e técnico, situadas no estado de São Paulo. Sessenta e um professores responderam a três questionários e oito docentes considerados iniciantes, segundo Huberman (1989), ou seja, lecionando há até 3 anos nessa instituição, participaram de um grupo de discussão com 3 encontros. A análise dos dados empregada foi a do materialismo histórico-dialético, baseada em Vygotsky, com base nos Núcleos de Significação (NS) propostos por Aguiar e Ozella (2006, 2013). Neste texto discute-se um Núcleo de Significação intitulado: Estratégias para o acolhimento do docente iniciante em escolas técnicas. Conclui-se que um programa de mentoria pensado para o Centro de Estudo Tecnológico pesquisado cooperaria para um acolhimento do docente inexperiente de modo humanizado, proporcionando-lhe maior segurança.

Göçler, 21. yüzyılın problemlerinden birisidir. Yoksulluk, gelir adaletsizliği, iç savaşlar, silahlı çatışmalar, kıtlık vb. nedenlerle milyonlarca insan göçmen durumuna gelmiştir. Ortadoğu’da etkisini gösteren Arap Baharı sürecinde Suriyede de iç karışıklıklar yaşanmış, olayın iç savaşa dönüşmesi ile 6 milyondan fazla Suriyeli ülkelerini terk etmek zorunda kalmıştır. Suriyelilerin ilk tercihleri komşu ülkeler olmuş, Türkiye, hem coğrafi yakınlık hem de “açık kapı” politikası ile Suriyeli göçünden en fazla etkilenen ülkelerin başında yer almıştır. Türkiye’ye göç eden Suriyelilerin en çok tercih ettiği yerleşim yerleri ise büyük kentler olmuştur. Gaziantep, İstanbul’dan sonra en fazla Suriyeliyi barındıran ikinci büyükşehir konumundadır. Araştırmanın amacı, Gaziantep Büyükşehir Belediyesi’nin Suriyeli göçmenlere yönelik yardım faaliyetlerini değerlendirmektir. Bu çerçevede, Gaziantep Büyükşehir Belediesi’nin haberler portalındaki Suriyelilere yönelik haberler derlenerek kodlanmış ve veriler analize hazırlanmıştır. Maxqda Analytics Programı yardımıyla veriler analiz edilmiş, görsel araçlar kullanılarak açıklanıp değerlendirilmiştir. Sonuçta Gaziantep Büyükşehir Belediyesi’nin “eğitim, çocuklara yönelik faaliyetler ve sosyal uyumun sağlanması noktalarında Suriyelilere yönelik faaliyetlerde bulunduğu görülmüştür. Kent kimliğinin korunması ve alt yapı kapasitesinin geliştirilmesi hususlarında ise kent genelinde sorunlar yaşandığı söylenebilir. Büyükşehir belediyesinin mali imkânlarının Suriyelilere yönelik yardımlar için yetersiz kalması, kayıtdışı istihdanım kontrol altına alınamaması gibi hususların bu konuda etkili olduğu anlaşılmıştır.
discussão sobre a teoria da textura e o conceito de densidade-compressão de Wallace Berry
Authors: Jara Alejandro , Irlandini Luigi Antonio
Published: October 2023

A teoria da textura desenvolvida por Wallace Berry permite visualizar o papel que a textura desempenha dentro da música, podendo relacionar tal elemento com o delineamento da forma musical. No entanto, as análises feitas por Berry podem não ser aplicáveis a repertórios em que a componente temporal dominante seja diferente à linearidade, ou o devir, dos períodos clássicos e românticos, ou seja, repertórios que têm como poética composicional temporalidades não-lineares que tendem ao presente do ser. Nesse tipo de repertorio, a teoria de Berry pode ser aplicável parcialmente, isto é, unicamente sobre os aspectos quantitativos, a saber, os conceitos de densidade-número, densidade-compressão e espaço-textural. Este trabalho aprofunda-se no indicador de densidade-compressão proposto por Berry, o qual é modificado para identificar os segmentos de alta compressão, avaliando, assim, as caraterísticas de compressão a partir de suas disposições internas, e não de seus aspectos globais, como fora definido por Berry.

The need for energy for the purpose of thermal comfort in buildings is constantly growing. To minimize this need, we can improve the performance of the building envelope, which is the seat of several thermal stresses, which encourages us to develop, apart from renewable or alternative energies, construction materials for buildings capable of storing energy. For this, the integration of innovative passive materials in the building envelope makes it possible to reduce energy consumption and ensure thermal comfort in countries with a very hot climate such as the desert zone of Chad. We were thus interested in the characterization of diatomite which is used to build a good majority of dwellings in the Lake Chad, Kanem and BET regions. To this end, samples of diatomite used in the construction were taken from Faya, the capital of the far north of Chad, on which we carried out mineralogical analyzes as well as thermal and mechanical characterization. Observations at the SEM, analyzes by fluorescence of rays X and Diffractograms clearly confirm pure diatomite. Furthermore, the results of the various thermo-physical and mechanical tests presented a material which has a low mechanical resistance but a good thermal resistance. Therefore, the diatomite which has been the subject of this study has no negative effect on the environment, it is an excellent thermal insulation material capable of storing thermal energy in buildings.

This paper mainly determines the comparison of reliability of an existing rural area & urban area LVDS (low voltage distribution system) with their respective proposed high voltage distribution system (HVDS) and also including their 33/11 kV Substation. Ring main substation and single bus bar substation configuration are considered for urban and rural distribution systems respectively. The reliability of ring bus substation used in urban area is more as compared to single bus substation used in rural area. The load point reliability indices are calculated considering both substation reliability indices and radial feeder indices. The substation failure rate is calculated by considering overlapping outages approach and whereas the radial feeder indices are calculated by using cut set approach. Further, the LVDS Network is converted into the HVDS Network by replacing a high rating distribution transformer (DTR) supplying to a group of customers with Large in number with multiple small rating distribution transformers near to consumer terminals with less number of customers in each group. This conversion leads to Minimum length of LT Lines in HVDS Which results in improving voltage profile, reliability and efficiency. In this paper the disconnecting switches and alternative supply are also considered on both LVDS and HVDS Networks in the calculation of the reliability of to assess the reliability of the radial distribution system (FMEA)Failure mode effect analysis is used. This study uses a LVDS and HVDS system, and uses an alternative power source and disconnectors, to determine reliability indices of the rural area network and urban area network distribution system. In this paper the important distribution reliability indices to reduce system average interruption durations (SAIDI), Energy Not Supplied (ENS) and ASAI for LVDS and corresponding HVDS are calculated. The research idea is proposed on a Indian practical networks.

The key element for mechanics of every vehicle be it a 2-wheeler, 3-wheeler, 4-wheeler and so on requires engine oil to work smoothly. Engine oil's primary function is to lubricate the moving elements of engines, which are constantly undergoing friction. As a result, friction is decreased, which tends to diminish longevity of engine parts. During combustion, energy is wasted, and mechanical parts rubbing against one another raise engine temperature. With increased usage the engine takes a lot of wear and tear this leads to accumulation of impurities in the oil. The project describes the design and development of an IoT based oil impurities, level monitoring instrument and its operational methodology. This project uses a unique approach with LED spectrophotometry. The developed instrument in the project will do Qualitative and Quantitative assessment of lubricant oil in IC engine’s sump. This in turn aids in carrying out decisive actions to maintain the ecological emissions and engine life cycle.

To mitigate the detrimental impacts of disposing of used cooking oil (UCO) into the environment, which adversely affects marine life, human health, and agricultural outputs, this research proposes a novel approach incorporating this waste material into the concrete industry as a chemical admixture. To investigate this, an initial experimental program is designed to examine how used cooking oil affects various fresh properties and compressive strength at 3, 7, and 28 days of age of concrete. Concrete batches of M40 grade are meticulously prepared with varying proportions (ranging from 0% to 2%) of used cooking oil. To predict strength characteristics, an Artificial Neural Network (ANN) is employed, consisting of three layers. The input layer comprising quantities of cement, coarse aggregate, fine aggregate, water content, super plasticizer, and the percentage of the chemical admixture (UCO), hidden layer for predicting the network system and the output layer providing the concrete's compressive strength.

In this paper, we have developed a solution for securing patient medical records based on blockchain. In our approach, we first carried out a comparative study of different blockchains. This comparative study, based on the Ethereum, Corda and Hyperledger Fabric blockchains, enabled us to select Hyperledger Fabric as the development framework for our blockchain. The criteria justifying our choice are essentially: the modularity of the architecture, the variety of programming languages for smarts contracts, the possibility of creating private channels between members of a network, high access control and data confidentiality, and a flexible consensus model. These criteria are crucial as they guarantee both the robustness and flexibility of the network in a shared medical record context. The proposed solution is a decentralized application that exchanges data in a consortium-type blockchain network, with three different organizations in a healthcare pathway: a hospital, a pharmacy and a laboratory. Other organizations can be added to the network taking into account the need to share and secure healthcare information. Our solution uses the IPFS (Interplanetary File System) protocol for distributed document storage, increasing data security and availability. To facilitate exchanges between network nodes, particular emphasis was also placed on the choice of consensus algorithm. First we chose the Solo Orderer algorithm, which uses a single Ordering Service node to process transactions and add them to blocks, and then we used the Kafka orderer algorithm, which offers high scalability and robust resilience in production environments. The choice of these two consensus algorithms enabled us to set up and deploy a blockchain network that stores and secures sensitive data from medical analyses or examinations in a patient's care pathway.

This study attempts to find out the determinants that have significant impact on the extent of related party disclosure. Albeit, related party is one of the most important reasons for corporate scandals, very few researches have been conducted to find the determinants of related party disclosures particularly in developing countries’ perspectives. This motivated the authors to find the determinants of related party disclosures. For conducting this study, a disclosure index of 28 disclosure items has been prepared and the annual reports of 102 listed non-financial firms for the year 2019-2020 of Dhaka Stock Exchange (DSE) were scrutinized against this disclosure index. The findings show that the related party disclosure by the sample companies is on an average 37.36%, which indicates that the current scenario of related party disclosure is not satisfactory. The regression analysis was done to find the determinants of related party disclosures. The results show that the association between the extent of related party disclosure and Multinational Subsidiary is statistically significant. The Security Category has negative but significant impact on the extent of disclosure. The result of this study will add value to the existing literature by providing the empirical evidence of the determinants of related party disclosures from a developing country’s perspective. From practical point of view, the outcome of this paper will help the regulators like Securities & Exchange Commission (SEC) to form a frame of reference for the related party disclosures requirement. The results of this study will also help future accounting researchers to work on this area and the investors to make investment decision on the non-financial companies.
