Published: February 2024

Abstract. Using a 1/12° regional model of the Northwest Atlantic Ocean (MOM6-NWA12), we downscale an ensemble of retrospective seasonal forecasts from a 1° global forecast model. To evaluate whether downscaling improved the forecast skill for surface temperature and salinity and bottom temperature, the global and downscaled forecasts are compared with each other and with a reference forecast of persistence using anomaly correlation. Both sets of forecasts are also evaluated on the basis of mean bias and ensemble spread. We find that downscaling significantly improved the forecast skill for monthly sea surface temperature anomalies in the Northeast U.S. Large Marine Ecosystem, a region that global models have historically struggled to predict skillfully. The downscaled SST predictions for this region were also more skillful than the persistence baseline across most initialization months and lead times. Although some of the SST prediction skill in this region stems from the recent, rapid warming trend, prediction skill above persistence is generally maintained after removing the contribution of the trend, and patterns of skill suggestive of predictable processes are also preserved. While downscaling mainly improved SST skill in the Northeast U.S. region, it improved bottom temperature and sea surface salinity skill across many of the marine ecosystems along the North American East Coast. Downscaling generally reduced the mean surface salinity biases found in the global model, particularly in regions with sharp salinity gradients (the Northern Gulf of Mexico and the Northeast U.S.). In some cases, however, downscaling amplified the surface and bottom temperature biases found in the global predictions. We discuss several processes that are better resolved in the regional model and contribute to the improved skill, including the autumn re-emergence of temperature anomalies and advection of water masses by coastal currents. Overall, the results show that a downscaled, high resolution model can produce improved seasonal forecast skill by representing fine-scale processes that drive predictability.
Southern Ocean Ice Prediction System version 1.0 (SOIPS v1.0): description of the system and evaluation of synoptic-scale sea ice forecasts

Published: February 2024

Abstract. An operational synoptic-scale sea ice forecasting system for the Southern Ocean, namely Southern Ocean Ice Prediction System (SOIPS), has been developed to support ship navigation in the Antarctic sea ice zone. Practical application of the SOIPS forecasts had been implemented for the 38th Chinese National Antarctic Research Expedition for the first time. The SOIPS is configured on an Antarctic regional sea-ice‒ocean‒ice-shelf coupled model and an ensemble-based Localized Error Subspace Transform Kalman Filter data assimilation model. Daily near-real-time satellite sea ice concentration observations are assimilated into the SOIPS to update sea ice concentration and thickness in the 12 ensemble members of model state. By evaluating the SOIPS performance on forecasting sea ice metrics in a complete melt-freeze cycle from October 1, 2021 to September 30, 2022, this study shows that the SOIPS can provide reliable Antarctic sea ice forecasts. In comparison with the OSISAF data, annual mean root mean square errors of the sea ice concentration forecasts at leading time of up to 168-hour are lower than 0.19, and the integrated ice-edge errors of sea ice forecasts in most freezing months at leading times of 24-hour and 72-hour maintain around 0.5 × 106 km2 and below 1.0 × 106 km2, respectively. With respect to the scarce ICESat-2 observations, the mean absolute errors of the sea ice thickness forecasts at leading time of 24-hour are lower than 0.3 m, which is in range of the ICESat-2 uncertainties. Specifically, the SOIPS has a promised capacity in forecasting sea ice drift, both in magnitude and direction. The derived sea ice convergence rate forecasts have a high potential in supporting ship navigation on local fine scale.
Probabilistic Flood Inundation Mapping through Copula Bayesian Multi-Modelling of Precipitation Products

Published: February 2024

Abstract. Accurate prediction and assessment of extreme flood events are crucial for effective disaster preparedness, response, and mitigation strategies. One crucial factor influencing the intensity and magnitude of extreme flood events is precipitation. Precipitation patterns, particularly during intense weather phenomena such as hurricanes, can play a significant role in triggering widespread flooding over densely populated areas. Traditional flood prediction models typically rely on single source precipitation data, which may not adequately capture the inherent variability and uncertainty associated with extreme events due to certain limitations in precipitation generation framework, availability or both spatial and temporal resolutions. Moreover, in coastal regions, the complex interaction between local precipitation, river flows and coastal processes (i.e., storm tide) can result in compound flooding and amplify the overall impact and complexity of flooding pattern. This study presents an implementation of Global Copula-embedded Bayesian Model Averaging (BMA) (Global Cop-BMA) framework for improving the accuracy and reliability of extreme flood modelling. The proposed framework integrates a collection of precipitation products with different spatiotemporal resolutions to account for uncertainty in forcing data for hydrodynamic modelling and generating probabilistic flood inundation maps. The methodology is evaluated over Hurricane Harvey, a catastrophic weather event characterized by intense precipitation and compound flooding processes over the city of Houston in the state of Texas in 2017. The results show a significant improvement in predictive accuracy compared to those based on a single precipitation product, demonstrating the merits of the Global Cop-BMA approach. Furthermore, the research extends its impact by generating probabilistic flood extension maps that account not only for the primary influence of precipitation as a flood driver but also for the intricate nature of compound flooding processes in coastal environments.

Employee intentions to leave may entail expensive consequences for the organization. This study examined the mediating impact of employee engagement on the relationship between workplace bullying and employee intentions to leave. This study adopts a quantitative approach to find the relationship between variables. The data was collected from the banking sector of Pakistan through a random sampling technique using a self-administered questionnaire where 350 was the sample. Structural equation modeling (SEM) analysis showed that employee engagement substantially mediates the relationship between workplace bullying and the intention to leave the organization. However, workplace bullying and the intention to leave the organization are positively associated. The results were integrated from a conservation of resources perspective and recommendations for practice were made.
Demography and Inequality: The Effect of Tax Composition
Authors: Sheraz Rajput , Memon Abdul Basit , Tahir Rehan , Raza Kashif
Published: February 2024

This paper investigates how aging societies lead to worsen distribution of income through tax composition measured by ratio of direct taxes to indirect taxes. The rationale follows: due to the political power of working age population emanating from majority of their share in the population, in a median voter model, they manage to shift the tax burden on aged population in an aging society through increasing direct taxes more than indirect taxes. This results in elevating income inequality in society. To estimate our hypothesis, we apply panel data using time and country fixed effects. Based on sample covering 110 countries from 1990-2020 and applying different inequality measures and robustness check, the empirical evidence considerably supports this hypothesis. The results hold firmly across the OECD and non-OECD countries together with strong and weak democracies.
Marginalization, Patriarchy, and Religion: A Feminist Study
Authors: Ansari Maryam Hassan , Ahmed Zia , Nayab Durr- e-
Published: February 2024

Even though organizations have been developed to eradicate, marginalization is still in vogue for third-world women. Prima Facie evidence in support of the fact can be found in profession, religion, or gender. The patriarchal setup with works of literature and media as co-actors leaves nothing unturned to achieve this ultimate objective. However, the mutinous pen of a Pakistani writer, Muhammad Hanif, presents the rebellious ideology and marginalization of suppressed women. Hanif’s portrayal of Alice in his work entitled “Our Lady of Alice Bhatti” is an accurate picture of a wretched third-world woman facing marginalization based on her gender, religion, and profession. The researcher has studied chunks of text under the theoretical lens of Spivak and Said’s proponents that a third-world woman is doubly marginalized (Spivak, 1993), and she is created as a traditional Asian woman (Said, 1991). The most probable outcome of the study of Alice’s marginalization is that the minority is prone to be suppressed, and if it is a female, then the chances of betterment are near zero.

Published: February 2024

The study was designed to determine the ICT as fostering potential factor in ECCE classrooms of Punjab province of Pakistan.  The research design was quantitative and the mode of the study was descriptive research by nature. About 300 ECCE teachers from two districts of Punjab Province i.e. Sahiwal and Bahawalpur were selected randomly. A questionnaire was used to get the true picture from the sample of the study. Results revealed that although ECCE teachers have their own laptops / computers, but they are still reluctant in using ICT resources for teaching learning process in their classrooms. Additionally, a majority of ECCE teachers have no sufficient skills to effectively operate ICT tools, and many of them had not received any pre-service training to enhance their ICT competencies. The lack of ICT facilities, quality of internet, prior knowledge and insufficient skills of ICT were the major obstacles in successful integration of ICT at ECCE level. The government should take special initiatives to provide basic ICT infrastructure, allocate special grants and conduct adequate trainings for ECCE teachers.
The Commemorative Use of Social Alienation and Displacement in Ice-Candy Man by Sidhwa
Authors: Raza Saima , Hashmi Zoya , Naseer Ayesha , Arshad Junaid
Published: February 2024

Any kind of evil prevailing in society damages the system on a general level and hurts humans at individual level. Living peacefully and becoming no harm to the other members of society is the first rule of humanity and colonization is one of the major social wrongdoings that ended up affecting nations and societies. With this background, this particular study tends to explore social alienation and displacement from Robertson et al. (1994), as an effect of colonization. This research bases upon the psychological and physical state of the colonized in context to their feelings and actions presenting how the colonization traumatized them with emotions of detachment and loneliness by analysing Sidhwa’s novel Ice-candy Man. The study depends upon the qualitative approach in which the theory of social alienation and displacement is used to analyze the text, implementing the physical and metaphorical displacement and effects of involuntary exile by Robertson et al. (1994). The findings of the research clarify the fact that colonization has a clear influence on social alienation and displacement not only in the physical way but also in extraordinarily subtle and psychological ways. This research draws attention towards how something physically insignificant as displacement without even being moved and alienation without getting socially alienated ruin lives. How harmfully it ignites the engine of utter hatred and revenge and brutally it turns out by destroying not just individuals but communities prevailing hatred and vengeance for coming generations. This research has the tendency to give base to new research that may try to solve issues of subtle displacement and alienation and how it ends in the long run.

The article discusses an information system that allows optimizing business processes and IT processes through automation using project management tools and designed to integrate existing subsystems. Special tools are used to design any technologically complex system. An architect draws up a project plan, an engineer draws up a detail drawing. A business is also a complex system with many connections, objects and interactions. To build a business architecture, special business modeling systems are used, one of which is the Fox Manager BPA program. In order to solve problems systematically, rather than intuitively, it is necessary to design the architecture of the business, prescribe rules and standards of work, distribute responsibility for functions among the staff and monitor their implementation. An information system for decision support using heterogeneous spatial data to optimize the company's management process is presented. The methodology proposed for the verification of IP is used for the first time in the systems under study. The article also presents studies of topical issues in the field of information technology in the field of telecommunications. In modern conditions, information technology (IT) in companies is present as a necessary attribute of technology for managing the process of production of goods and services, economic analysis and management decision-making. Currently, IT is used in many areas of management activity, and is increasingly becoming an important factor and means of solving numerous management tasks. Special tools are used to design any technologically complex system.

Современность ставит перед измерительными системами огромные и все возрастающие задачи. Удовлетворение этих требований становится возможным при объединении дисциплин, находящихся на границе многих дисциплин: физики, химии, электроники, механики и т.д. В результате таких сочетаний волоконно-оптические технологии вошли во многие отрасли науки и техники, уже найдя применение во многих областях и специальностях. К числу таких областей относятся, в частности, измерительные системы на основе волоконно-оптических датчиков. В статье отражены вопросы, связанные со встроенными в композит оптоволоконными датчиками на основе волоконных брэгговских решеток (ВБР), которые позволяют измерять распределения деформации при механической нагрузке. Конструкции из композитных материалов часто подвергаются внешним возмущениям окружающей среды, которые могут привести к повреждениям, поэтому требуют мониторинга качества состояния конструкции в реальном времени. Более подходящие датчики для таких целей–это волоконно–оптические датчики на основе решеток Брэгга, поскольку они способны достигать целей диагностики, мониторинга состояния и быть очень компактными по размеру, а также могут быть встроены в структуры. На основе проведенных испытаний, предваряемых расчетами и компьютерным моделированием, демонстрируется влияние параметров используемых алгоритмов статической оптимизации на точность распределения напряжений, измеряемых с помощью волоконно-оптических брэгговских решеток. Представленные в работе численные расчеты и экспериментальные результаты позволяют создать оптоволоконный датчик, который можно использовать в композитной структуре.

На сегодняшний день защита окружающей среды является актуальной проблемой. В связи с этим, одним из приоритетных задач государства является снижение вредных выбросов в энергетике. Известны различные методы, такие как совершенство технологического процесса, использование возобновляемой энергии и т.д. Данная работа посвящена еще одному перспективному варианту по снижению вредных выбросов – это использование водорода в качестве безуглеродного топлива. Авторами предложена конструкция нового горелочного устройства для сжигания газообразного топлива с возможностью добавления водорода в зоне перемешивания и проведен численное исследование. Горелочное устройство состоит из нескольких элементов, в частности входного лопаточного устройства, зоны сужения, сопел для подачи газообразного топлива и водорода, а также выходного лопаточного устройства. Основной целью статьи является анализ аэродинамических характеристик, а также численное иследование влияния добавления водорода в новом, предложенным авторами горелочном устройстве. В статье представлены результаты моделирования в виде графиков зависимостей температур, концентраций оксидов азота и углексилого газа в уходящих газах, а также контуров температур от доли водорода в топливно-воздушной смеси. Проведенный анализ показывает, что добавление водорода имеет преимущества в виде низких концентрации углекислого газа, но также и обладает недостатком в виде увеличения температуры в зоне горения, что приводит к увеличению концентраций оксидов азота.

Производство электроэнергии от ветряных генераторов получило широкое распространение. Он занимает большую долю на мировом рынке производства электроэнергии в качестве ветряной турбины. Существует несколько типов ветряных турбин: ветряные турбины с горизонтальной осью, ветряные турбины с вертикальной осью и безлопастные ветряные турбины. Вихревой безлопастный ветродвигатель представляет собой резонансную ветряную турбину, вызванную вихревой вибрацией, которая считается наиболее экологически чистой ветряной турбиной. Что касается стартапа в Испании, Vortex Bladeless Ltd экспериментирует с тем, как добиться максимальной эффективности преобразования энергии безлопастной ветряной турбины, поскольку это еще не полностью завершено с нулевой коммерциализацией. Следовательно, Целью исследования является анализ нескольких форм и конфигураций вихревой безлопастной ветровой турбины с использованием вычислительной гидродинамики, а затем определение значения аэродинамических характеристик безлопастной ветровой турбины для определения оптимальной формы вихревой безлопастной ветряной турбины. Метод, использованный в этом исследовании, заключается в запуске 2D и 3D модели вихревой безлопастной ветряной турбины, разработанной в SolidWorks, в моделировании вычислительной гидродинамики с использованием программного обеспечения Ansys-Fluent. Две основные конструкции 3D-модели вихревой безлопастной ветряной турбины представлены пятью различными конфигурациями каждая. Данные моделирования интерпретируются несколькими способами, один из которых основан на средней скорости вершины и графике, извлеченном из процесса быстрого преобразования Фурье (БПФ). Получена наиболее оптимальная конфигурация вихревого безлопастного ветродвигателя – конструкция А4, имеющая наибольшее значение fv/fn, равное 0,62, а также аэродинамическую характеристику и параметры, влияющие на выбор конфигурации. Предложение для будущей работы состоит в том, чтобы детализировать массовую часть формы безлопастного ветряного двигателя и использовать усовершенствованный способ получения данных из БПФ.

Maize is grown in areas with environmental conditions that are ideal for growth of most cereal pathogens such as Fusarium fungi. However, there is lack of effective fungicides to control fumonisin producing Fusarium. This study was conducted to determine the efficacy of atoxigenic Aspergillus flavus (Aflasafe KE01) on the population of Fusarium species in maize fields. The study was carried out in four sub counties in lower Eastern Kenya (Kaiti, Kathiani, Nzambani and Wote). Twenty-four maize fields were selected in each sub county where 12 fields were treated with Aflasafe KE01, while 12 fields comprised the untreated controls. Aflasafe KE01 was applied by hand broadcasting in the maize fields two to three weeks before tasselling of maize. Maize grain samples were collected from each field at harvest and ground using a Bunn coffee mill grinder. Fusarium species were isolated from the ground maize using pour plate method following serial dilution on low strength potato dextrose agar (PDA)and Spezieller Nahrstoffarmer. The results showed that application of Aflasafe KE01 effectively displaced toxigenic Fusarium species in maize fields. Maize samples from Aflasafe KE01 treated maize fields recorded significantly lower incidence (41%) of the Fusarium species compared to untreated maize fields (60%) (p≤0.01). These results indicate that Aflasafe KE01 is a potential biopesticide for the biocontrol of Fusarium species in maize. Key words: Aflasafe KE01, atoxigenic Aspergillus sp, Fusarium species, maize.

This study aims to determine the factors and analyze to find out the legal basis regarding trade in mother’s milk. And to find out the views of the schools of thought regarding the Trade of mother’s milk. This research uses normative research methods. Data collection in this study is the view of the schools of thought regarding the Trade of mother’s milk (breast feed). The results of this study indicate that Imam Hanafi and Hanbali that Trade in mother’s milk is prohibited, because mother’s milk is a part of the human body as well as blood, eyes and other body parts. In addition, mother’s milk is also not a market object that can be traded, so it is forbidden to be traded. Meanwhile, according to Iman Maliki and Imam Syafi'i, it is permissible to buy and sell mother’s milk, because mother’s milk is a sacred object and can be used for babies, and it is lawful to drink it, so it can also be traded like sheep's milk. In addition, the difference is in the sacred as a condition for the validity of the object being traded and having a sale value. Imam Maliki and Shafi'i made it sacred and useful as a condition for the validity of the object being traded. Meanwhile, according to Imam Hanafi and Hanbali that sacred objects cannot necessarily be traded, for example natural water. Likewise with breast feed.
