Authors: Azam Javeria , Durrani Rukhsana
Published: May 2024

A successful recruitment policy ensures the selection of competent and qualified teachers for the education as well as the overall development of students. Primary education is the foundation of the entire education system. but unfortunately, Pakistan stands at a very low position among other countries of the world in Primary Education. The lack of competent teachers is a major issue in Pakistan. This study was designed to analyze the alignment of recruitment policies for primary school educators in Punjab according to eight indicators that were derived from the National Professional Standards for Teachers in Pakistan. This study was qualitative, so, firstly, the alignment of recruitment policies of 2018 and 2022 with National Professional Standards was analyzed through document analysis. Secondly, members of the district recruitment committee were interviewed to explore the assessment criteria of selection for primary school educators. Trustworthiness was ensured with data source triangulation. The findings revealed that recruitment policy is not aligned with National professional standards for teachers. The interview process for the selection of primary educators needs to be strengthened for the evaluation of future educators.
International Forced Migration and Employment Relations: The Case of Syrians in Türkiye
Authors: Uludağ Güler Çiğdem , Bükey Abdullah Miraç
Published: May 2024

Due to the political unrest following the civil war in 2011, several million Syrians had to flee from their own country to save their lives. The mass migration movement of Syrians, first within the country and then towards neighboring countries, brought many socio-economic problems. One of the worst hit nations is Türkiye, because of forced migration from Syria, where there are roughly five million registered and unregistered migrations. Although it has been nine years since the process began that was initially established as a temporary solution, and as a resolution could not be found, the dream of returning Syrians has weakened over time. This study aims to reveal how Syrians, who are included in the labor market in an unplanned way, affect the Turkish labor market. Dynamic Panel data analysis was performed using the data from 26 regions in Türkiye. As a result, a 1% increase in the immigration rate, which represents the share of Syrian immigrants in the region’s population, increases the employment rate by approximately 0.02%.
A class of central unstaggered schemes for nonlocal conservation laws: Applications to traffic flow models
Authors: Belkadi Said , Atounti Mohamed
Published: May 2024

This study introduces a new class of central unstaggered finite volume methods that are used to approximate solutions to nonlocal conservation laws. The proposed method is based on Nessyahu and Tadmor's (NT). Instead of solving Riemann's problems at the level of cell interfaces, as in the NT scheme, the approach we develop implicitly uses ghost cells while still generating the numerical solution on a single grid. We use our method with the aim of solving one-dimensional nonlocal traffic flow problems. The numerical results we present demonstrate the accuracy, high resolution, and non-oscillatory nature of the proposed method and compare very favorably with those obtained using the original NT method, demonstrating the expected simplicity of a family of unstaggered central schemes and confirming that nonlocal traffic flow models can be treated very efficiently by the suggested method.

Authors: El Guazouani Aziz , Abdou Amir Fouad Ibrahim , Elomari M'hamed , Melliani Said
Published: May 2024

In this paper, we investigate the existence and uniqueness of solutions for fuzzy boundary value problems involving fuzzy Caputo fractional derivatives of order q 2 (2, 3). As a preliminary step, we construct a generic structure of the solution associated with our proposed model by utilizing the Green’s function. We establish the existence of a unique solution of the proposed model paired with the given initial conditions by using Banach fixed point theorem. At last, as application, an illustrative example is given to show the applicability of our theoritical results.

Authors:   The National Ribat University, Sudan., Mahjoub Shaza Babiker Mohammed
Published: May 2024

Tuberculosis is a chronic granulomatous disease caused by various strains of mycobacteria, usually Mycobacterium Tuberculosis in humans. Robert Koch, a German physician, discovered the Tuberculosis bacillus in 1882 [1]. It has been a worldwide major health problem for centuries. Although the disease’s prevalence reduced decades ago, it still has extremely high prevalence in Asian and African countries. It may take any form clinically, but with decline in number, these tuberculosis lesions of oral cavity have become so rare that they are frequently overlooked in the differential diagnosis of oral lesions. Although, oral manifestations of tuberculosis has a rare occurrence, but it has been considered to account for 0.1-5% of all TB infections.

High-risk Human Papillomavirus (HPV) infections cause squamous intraepithelial lesions which act as precursors to invasive cancers. Due to the integration of HPV into host DNA, patients who have been diagnosed with HPV-associated invasive or preinvasive tumors may have a five-to-ten-fold increased risk of a second HPV-associated cancer, with a particularly strong association between anal and vulvovaginal cancers. This is a case report of a 26-year-old HIV-negative nulliparous female who developed independent squamous cell cancers of the vulvar, vaginal, cervix, and anus within a 2-year time frame in Cameroon. HPV specimens collected from the vagina and anus, and genotyped using the AmpFire HPV analyzer, revealed the presence of HPV Types 33, 51, and 68. Worldwide, HPV types 16 and 18 have been noted as the most virulent HPV types. Neither of these types was present in this patient with aggressive HPV-associated cancers. It is not known if the combination of these three types; 33, 51, and 68 forms a particularly virulent association in this population. This case demonstrates the importance of investigating less common high-risk HPV types and associated pathologies in this population. HPV genotypes other than 16 and 18 may play a significant role in cancer development in this population.

Background: Advances in screening have led to almost half of the reduction in breast cancer mortality. Precocious diagnosis increasingly needs clinicians to better treat early breast diseases, such as DCIS, or DCIS with microinvasion (DCIS-Mi). Due to the increasing prevalence of DCIS-Mi. In this review, we will focus on study this entity and define current treatment options, especially the role of surgical approach in the overall treatment of DCIS-Mi to explore the current and future optimal management of DCIS-Mi. Methods: A PubMed search for relevant articles was performed using the following keywords by MeSH and free-word: breast cancer, DCIS, DCIS‐Mi, microinvasion, invasive ductal carcinoma (IDC), clinicopathological characteristics, prognosis and treatment. Results: Until 1997, the American Joint Committee on Cancer (AJCC) defined DCIS-Mi as a tumor with an area of invasion less than or equal to 1 mm as T1mic in the TNM staging system. Histologically, two distinct types of DCIS-MI was classified. Comedocarcinoma subtype of DCIS, the larger the size of a tumor’s DCIS component and multicentric foci of DCIS are more commonly associated with microinvasion. The roles of surgery in treatment of DCIS-Mi includes breast-conserving surgery, mastectomy, and surgical evaluation of the axilla. Current guidelines from the National Comprehensive Cancer Network (NCCN) recommend treating DCIS-Mi following surgery guidelines for DCIS. The overall prognosis of DCIS-Mi is excellent with survival at 5 years. Conclusions: An supposition of current available data indicates no survival benefit to an individual undergoing mastectomy versus lumpectomy and radiation (breast-conserving surgery). Whenever possible, breast-conserving therapy is the treatment of the first choice of DCIS-Mi. Among those unfavorable factors, the key factor is the ability to achieve negative final pathologic margins. Surgical assessment of the axilla, such as sentinel lymph node biopsy on all DCIS-Mi is recommended.

Induction By Quarantine: Stages and Effects of New Career and Technical Education Teachers' Development
Authors: Sun Jeffrey C. , Turner Heather A.
Published: May 2024

Based on a qualitative study of 19 new career and technical education (CTE) teachers' induction during COV=D we asked how did the new teachers work collaboratively and develop as a group with other teachers during the pandemic? Although teachers encountered challenges relatively consistent
with prior studies (e. g., frustrated with decisions and policies, placed on the fringes of the school's operations) our findings reveal that induction challenges and effects became more pronounced as perceived non-core teachers, requests to remedy matters became more urgent, engagement with
external networks became more distant and unprioritized, and the role of induction became even more significant than prior academic years. At the same time, CTE teachers recognized the equalizing effect between CTE and non-CTE teachers with online instruction and uncertainties caused by the
pandemic. Implications for research and practice are discussed.

Authors: Fletcher Edward C.
Published: May 2024

The changing workforce, the increasing importance of postsecondary education, the national emphasis on STEM occupations, and the disparities of populations to gain access and equity to postsecondary education and high-wage, highdemand, and high-skilled jobs are all challenges warranting
attention for practitioners, school stakeholders, scholars, and policymakers in career and technical education (CTE). The purpose of this article is to describe the historical nature of CTE leading up to current trends and issues in the field. Additionally, I discuss future directions for
the field. My discussion is based on the changing mission of CTE and related challenges regarding access and equity issues as the field evolves to prepare all students to attain postsecondary degrees and to compete for high-demand, high-wage, and high-skilled occupations.
СИНТЕЗ ПАРАЦЕТАМОЛА В МИКРОВОЛНОВОЙ ПЕЧИ
Authors: Есаян П.А.
Published: May 2024

Парацетамол (ацетаминофен) - широко используемый лекарственный препарат во всем мире, обладающий жаропонижающим и обезболивающим действием. Он эффективен при лихорадке и слабых или умеренных болях, таких как головная боль, боль в спине или мышцах. Парацетамол обычно хорошо переносится и вызывает мало побочных эффектов на организм. Обладая анальгезирующим действием, парацетамол является составной частью ряда лекарственных препаратов.
Защита окружающей среды в последнее время приобретает первостепенное значение из-за постоянного увеличения количества образующихся токсичных и опасных загрязняющих веществ. “Зеленая химия”, также известная как “экологически безопасная химия”, - это развивающаяся область химии, которая фокусируется на четырех принципах: повторном использовании, сокращении, вторичной переработке и рекуперации. Основной целью “зеленой химии” является минимизация использования токсичных растворителей и отказ от использования опасных материалов в химическом синтезе. Микроволновая печь – важнейший инструмент для развития “зеленой химии”. В последнее время СВЧ-излучение (сверхвысокочастотное излучение) используется для синтеза лекарств. Оно позволяет проводить эти реакции с высокой скоростью и эффективностью, что снижает затраты на производство лекарств.
В данной работе описан метод синтеза парацетамола, основанный на ацилировании п-аминофенола уксусным ангидридом в присутствии гетерогенного катализатора H-клиноптилолита. Синтез проводился в микроволновой печи “Электроника СП-23 ЗИЛ” (Россия), частота - 2450 МГц, что позволило значительно сократить время реакции и повысить ее выход. Установлено, что воздействие микроволнового излучения значительно ускоряет реакцию и увеличивает выход парацетамола.
Для установления индивидуальности получаемого парацетамола предложено использование трех типов элюентов в тонкослойной хроматографии. Идентификация выделенного продукта произведена методами инфракрасной (Specord IR-75) и ЯМР 1H (Varian USA Mercury Plus (300 МГц)) спектроскопии.

The paper presents the results of studies of antioxidant properties of the leaves of the English oak (Quercus robur), Georgian oak (Quercus iberica), white willow (Salix alba) and common sycamore (Lycium barbarum) leaves. It is shown that all the studied extracts have antioxidant properties. The antioxidant capacity of the investigated extracts is studied on the example of the model reaction of the initiated oxidation of cumene. Azo-di-isobutyronitrile (AIBN) was used as a source of a free radical, and chlorobenzene was used as a solvent. The oxidation of the substances is carried out on a manometric installation with automatic pressure regulation. The total content of antioxidants in the studied extracts was determined by the known method. It is shown that the oxidation of cumene in the presence of all the used extracts takes place in the kinetic curves of oxygen absorption with well-defined induction periods. This indicates the presence of antioxidant substances in the extracts. The measured concentrations of the absorbed oxygen during time t <  were aligned in coordinates using the known method. The obtained data indicate that the mentionned extracts used are slightly inferior to synthetic-classical antioxidants in terms of antioxidant activity. Thus, the reaction rate constant k7 with cumyl peroxide radicals for -naphthol at 333 K is equal to 1,6•105 l/mol.sec, for hydroquinone – 1,2•105, for ionol - 2•105. It was established that, of the studied extracts, the largest number of antioxidants is contained in the extract of Greek oak leaves (1,34•10-4 mol/l in one mg), and the highest antioxidant activity is shown to be in the extract of white willow leaves (1,01•105 mol/l.sec).
By comparing the obtained results to the content of antioxidant substances (f.[InH]) and to the antioxidant activity (k7) of the studied extracts, it was confirmed that the antioxidant activity does not depend on the concentration of the inhibitor, i.e. on the content of AO in the reaction mixture. АОА most likely depends on the construction of АО and 〖RO〗_2^. radicals, as well as on the medium of the reaction mixture. Such antioxidant activity of a number of leaves will contribute to their use for the storage of agricultural and food products, which will contribute to the reduction of costs in this process.

Poetic art in Urdu seems to be stunned in Balochistan as the multilingual environment of the province is completely overflowing with the poetic creation of the native languages. Amid such circumstances, Atta Shad proved to be the shining star in Urdu poetry as he introduced new trends in it. His mastery in the field of lexical choice is pretty enough to prove himself as a real morphologist. He lines are the reflection of nature, its beauty and Ata Shad’s close association with natural object which can best be observed in Balochistan. A point worth mentioning about Ata Shad’s poetic qualities is that his workṢ is a window through which one can peep into Balochistan. The present study presents a true picture of Atta Shad’s personality and his poetic works while at a time exploring the effects of poetic power on his personality. The study is likely to pave way for future researchers to explore Ata Shad as a person and a poet in the same shell.
Contribuições do PIBID para a (des/re)construção da educação física escolar

Published: May 2024

Este escrito distendeu-se das primeiras experiências relacionadas ao subprojeto “Educação Física na Escola: fundamentos e propostas em uma perspectiva crítica”, ligado ao Programa Institucional de Bolsas de Iniciação à Docência (PIBID) da Capes e tem como intento problematizar as implicações desse programa no processo de buscas pela ressignificação da Educação Física na escola, pois, embora essa área tenha passado por profundas transformações nas últimas décadas, sua prática pedagógica e sua função no currículo ainda são bastante questionadas, quadro que coloca o componente curricular perante um período de críticas, desconstrução e reconstrução. O subprojeto supracitado permite que licenciandos/as, bem como profissionais da área reflitam sobre essas questões. As atividades foram desenvolvidas da seguinte forma: discussões sobre os princípios norteadores do trabalho, inserção do/a bolsista no espaço escolar e grupo de estudo. Durante esse período inicial de envolvimento com o subprojeto, os/as bolsistas puderam conhecer e refletir sobre o cotidiano da escola, de modo a estabelecer ligações com as discussões abordadas no grupo de estudo que, a partir de um suporte teórico crítico propõe a problematização da realidade e a formação de cidadãos para intervir criticamente sobre ela. Através da experiência é possível constatar que o contato com a escola possibilitado pelo programa consente ao/à acadêmico/a à adoção de uma postura investigativa sobre as práticas da profissão docente, sobretudo, do componente curricular em estudo, e isso representa um passo a favor de sua reconstrução. Considera-se, portanto, o PIBID como uma alternativa significativa para o processo de ressignificação da Educação Física na escola.

The cultural memory of the formation of urban culture in the post-industrial era has driven the development of post-industrial landscapes. Post-industrial culture needs to be conveyed through functional spaces, and among various functional spaces within post-industrial landscapes, post-industrial landscape structures hold significant research value. Through a literature review, three main issues in current research on post-industrial landscape structures have been identified: disputes regarding design styles, scattered design and analysis logic, and the lack of specific case-based analyses. Therefore, this study introduces the Metaphor-Deconstruction-Empowerment (MDE) design logic and utilizes the Truss Red Gallery (TRG) in Caofeidian, Hebei, as a research subject for specific analysis, thus addressing these three research gaps. In the analysis process, this study provides specific analyses of the metaphors reflected in TRG's design symbol language and exterior colours. It also examines the deconstruction manifested in the overall space and design details. Furthermore, it analyzes the empowerment showcased in the expansion of architectural space functions, the application of parametric design techniques, and the use of green and low-carbon technologies. Finally, this study conducts an overall logic analysis of the MDE design logic in TRG's design and, in conjunction with the actual construction process of TRG, provides insights into future research directions for the MDE design logic.

Authors: Lin Zixi
Published: May 2024

The transition to sustainable energy sources in the transportation sector has led to the development and adoption of various alternative propulsion technologies. This document offers an analytical comparison between vehicles powered by lithium-ion batteries (LIBs) and those powered by hydrogen fuel cells (HFCs). It scrutinises the technical, economic, and environmental advantages and disadvantages of each. LIB and HFC vehicles are among the most notable competitors in this sector. On a technical level, LIBs offer higher efficiency and lower weight, while fuel cells provide extended range and rapid refueling capabilities. Economic modelling shows battery electric vehicles currently demonstrate the lowest total cost of ownership, though supportive policies could improve fuel cell competitiveness in heavy-duty applications by 2050. Both technologies provide major greenhouse gas emissions reductions versus conventional vehicles, with battery electric vehicles maintaining an advantage in most scenarios. However, resilient domestic supply chains for critical battery materials and hydrogen infrastructure must be established to enable wide-scale adoption. Safety risks exist but can be mitigated through preventative strategies. Overall, LIBs and HFCs have complementary strengths, positioning them to transform transportation sustainability. However, batteries currently hold advantages in light-duty vehicles, while fuel cells show promise in heavy-duty segments. Continued technology advances, cost reductions, infrastructure build-out, and supportive policies will be instrumental in realising the immense potential.

Authors: Zhang Ruxi
Published: May 2024

It appears that the environment must be sacrificed at this stage of fast urbanization and economic development, and balancing economic development and environmental conservation becomes a struggle. The greenhouse effect is a perpetual wake-up call for humanity from a macro perspective, while the urban heat island effect within cities continues to influence human life from a micro one. The paper aims to study the presentation of the urban heat island effect and some of the anthropogenic causes, as well as the presentation of global warming and the greenhouse effect on surface temperature change and the anthropogenic factors behind it by taking Tel Aviv, Israel as an example. This research suggests that Tel Aviv's average yearly temperature has risen over the last 51 years, which could be related to human-caused global warming. Besides, there is a strong association between UHI and building density, and the loss of green space in urban areas adds to the establishment of UHI. The study helps policymakers decide and develop effective mitigation technologies for the greenhouse effect and UHI for future city expansion to be sustainable.

Authors: Wang Yitong
Published: May 2024

Shape memory alloys (SMAs) are a family of functional materials with unique properties that make them ideal for use in seismic-resistant structures in civil engineering. SMAs undergo phase transformation in response to temperature and stress, enabling them to effectively absorb energy during dynamic loading cycles, thus maintaining structural integrity through their shape memory effect and pseudo-elasticity of phase transitions. This paper aims to summarize previous experiments conducted to identify the unique features of SMAs and their application advantages in steel, timber, and concrete components. Furthermore, areas where design and manufacturing can be improved to optimize the full potential of SMAs for practical and economic use during seismic forces or other dynamic loads are suggested. In conclusion, SMAs exhibit unique physical properties that make them an innovative solution for structural applications. The demand for highly reliable, seismic-resistant structures is increasing globally, and SMAs provide a reliable and economical alternative approach to satisfy this demand. The practical application of SMAs in civil engineering will contribute to the creation of new knowledge, innovative design possibilities for engineers, and safer structures for the population.
