Authors: Doğan Tacettin
Published: January 2023

In this study, it is aimed to examine the factors that cause anxiety disorders in educators working in educational institutions in educational management practices and educational processes. Anxiety disorders are a condition that is often observed as a normal process in people and managers working in all institutions and organizations, as well as in educational administrators and teachers working in educational institutions. Educational institutions are one of the most important building blocks that determine the future of countries. The work and functioning of educational institutions, their quality, qualification and future perspective are determined by the performance, characteristics and personal knowledge, skills and equipment of educational administrators and educators. In terms of ensuring that educators start working, continue working and fulfill their duties with willingness and enthusiasm, reducing anxiety disorders to a minimum level, or even resetting them if possible, is an indispensable necessity for educational institutions.

Good for tech: Disability expertise and labor in China's artificial intelligence sector
Authors: Wu Di
Published: January 2023

People with disabilities are often perceived as being “given” the opportunity to work, rather than “providing” valuable labor. Centering on disabled data workers as experts involved in the quotidian construction of artificial intelligence (AI) systems in China, this article shows that disability expertise and labor can afford a technical edge to AI systems in a certain political economy. In the case examined, the work of consistently synchronizing interpretations of the ambiguous data and elusive rules of smart home systems prefers a stable annotation workforce with coordinated cognition and trained judgment. This technical demand has come to be met by a committed team of skilled disabled workers, who are pushed out from mainstream job market by systemic ableism, and pulled in by disability-informed expertise that reconfigures space, time, and political economy to meet non-normative bodyminds. Through this exceptional case run by a disabled people led organization, I draw attention to disabled people’s under-examined role as system-builders of information technologies as opposed to users, victims, or inspirations, and highlight the transformative potential of disability expertise.
Analysis of Environmental Sustainability in the Holy Quran: Maqasid Framework
Authors: Abu-Rayash Azzam , Sabbah Eman
Published: January 2023

The current global challenges of climate change and sustainable development is rendering the world helpless with numerous failed attempts at addressing these critical issues. Exploring the Islamic worldview of environmental sustainability and conservation therefore is even more vital in these momentous times. This worldview features a purpose-spirited focus by exploring the higher objectives behind environmental sustainability as extrapolated from the Revelation. There are four main themes that are highlighted in the Quran in relation to the environment, including the concepts of corrupting (ifsaad) and bettering (islaah) earth, along with the key objectives of being custodians and inheritors of earth (istikhlaf/ isti’mar/ wirathah). The concept of utilization (taskheer) is coupled with the ‘communities like you (umam) that share the planet and resources with us. Derivatives of the term (fa sa da) have been mentioned 50 times in the Quran, 36 of which reference earth. Custodianship is highlighted in the Quran more than 30 times, with direct reference to earth mentioned 17 times. Facilitation includes many groups such as the sun and the moon, which was emphasized nine times, as well as stars, sea and cattle, each emphasized three times in conjunction with the facilitation theme. Stipulated values include the value of knowledge, respect, preservation, humbleness and responsibility. The collection of verses have been compiled, coupled with references from the Sunnah and Islamic jurisprudence, and analyzed in light of the maqasid methodology. Similarly, human groups can be classified further to reformers, corrupters, believers, non-believers, wrongdoers and hypocrites, while other communities such as animals, plants, mountains and other species fall under groups. Environmental sustainability from an Islamic worldview is defined in a distinctive and holistic manner which combines spiritual, social, economic, moral, honest, intellectual, and religious aspects into one core meaning. Although some creatures are facilitated for humans on Earth, they are communities like human kind which emphasizes that bettering and preserving the balance of Earth is the humans unique responsibility.
Maqasidi Approach and its Impact on the Science of Principles of Tafsir in the Thought of Imam al-Shafi’ie
Authors: Rouiba Driss
Published: January 2023

This study aims to shed some light on the contribution of Imam al-Shafi’ie to founding the science of the fundamentals of tafsir and channelling its related scientific issues in accordance with the maqasid perspective through his book entitled “al-Rissalah”. To attain this objective, the research intends to elucidate the concept of purposeful consideration and emphasize its importance in inculcating the science of fundamentals of tafsir, in addition to piloting the understanding of the meanings of Qur’anic verses. This paper also attempts to approach the centrality of purposefulness in originating the science of fundamentals of tafsir in “al-Rissalah” of al-Shafi’ie which represents a core pillar in the fundamentals of tafsir. To put more emphasis on the hegemony of purposefulness in guiding the understanding and giving meaning to thought and speech, the researcher intends to uncover some uses of purposeful consideration by Imam al-Shafi’ie that support its authority in the Qur’an by providing examples from the tafsir of the author of “al-Rissalah”.

Presence of Bald Ibises (Geronticus Wagler, 1832) (Threskionithidae - Aves) in the Late Pliocene of Bulgaria
Authors: Boev Zlatozar
Published: January 2023

Fossil data on the history of Threskiornithidae, as well as genus Geronticus are scarce. The only fossil species, G. apelex Olson 1985, was described from the early Pliocene deposits of South Africa. In 1993 a left proximal part of a carpometacarpal bone of an adult specimen was collected in the vicinity of the town of Slivnitsa (NW of Sofia, West Bulgaria). According to the associated fauna of large mammals, the age was determined final of Middle Villafranchian - end of MN 17 zone (over c. l.85 Ma B.P.). Diagnosis of Geronticus balcanicus sp. n.: A Late Pliocene Bald Ibis, dimensionally and morphologically close to Geronticus eremita, but differing by the less concave surface in the proximal end of os metacarpale minus; absence of an enlargement of os metacarpale minus in proximal end; smaller foramen nutritium; inclined, but not upright profile of trochlea carpalis; relatively larger diameter of trochlea metacarpalis; less erected processus pisiformis; less developed (shallower) fossa in the base of facies articularis ulnocarpalis; deeper fossa supratrochlearis and presence of an inception of processus intermetacarpalis. G. balcanicus sp. n. is considered as a probable ancestor of G. eremita, while G. apelex probably lies on the lineage of G. calvus.

Geodiversity of pseudokarst caves as the reason for their scientific importance and motive of protection
Authors: Urban Jan , Otęska-Badzyn Janina
Published: January 2023

Pseudokarst caves occur in various - magmatic, metamorphic and sedimentary - rocks and represent many genetical types. They have been lately a frequent subject of registration and scientific studies. The development of these caves is closely related to processes of rocks formation or postdiagenetic reconstruction, mainly denudation (erosion, weathering). Consequently the studies of these caves often provide wider information on processes controlling geological or morphological development of the area. Thus, the scientific criteria should be more often applied in the caves evaluation and selection for legal protection. In Poland the number of protected pseudokarst caves has been increasing for the last years and now legally protected caves represent more than 25% of the caves number and more than 40% of their total length.

Some sites and collections are tourist attraction. Others await “geotourism" development before they are lost. Interpretative media and visitors typology models are presented. Exemplars are given from Nonh America and Europe. A “geotourism” development strategy is proposed.
Geotourism, Conservation and Society
Authors: Larwood Jonathan , Prosser Colin
Published: January 2023

Geotourism is a rapidly increasing industry. In the UK areas such as the Giant’s Causeway on the Antrim Coast, Northern Ireland and the Dorset Coast of Southern England are world famous and visited throughout the year. The intrinsic attraction of these areas is geology whether as part of the landscape or as a resource to more directly enjoy and use. Geotourism offers both opportunity and threat to Earth heritage conservation. There is an established and strong framework for Earth heritage conservation in the UK involving site selection, documentation and safeguard. Central to this process is the need to promote our Earth heritage and its conservation. Gaining awareness and understanding at all levels, from international or national government to local community, will ensure continued support and backing for Earth heritage conservation. Geotourism offers a means for achieving such wider appreciation. The message and the audience must be carefully considered. An holistic approach, one that places geology in a wider context is deemed essential. Geology not only as part of the wider landscape and environment but also as central to our culture and history. Such an approach widens the appreciation of the specialist researcher or geology student and increases the personal relevance to the non-specialist — the wider public. Initiatives such as the identiﬁcation of "Natural Areas" in England and the development of the Pan-European Biological and landscape Diversity Strategy now start to address these very issues. It is essential, however, that geotourism is achieved in a framework of sustainable development. The needs of the environment, economy and society must be carefully balanced now and in the future. The impact of wider use through increased value must be carefully managed; the economic resource generated through geotourism should contribute to the maintenance and enhancement of the Earth heritage resource; and the needs of society, particularly the local community (not just the geotourist) should be met. The opportunities (and threats) that geotourism brings to Earth heritage conservation are discussed. In particular, the value of wider and integrated promotion is considered in establishing a societal culture that increasingly values our Earth heritage resource and the need to conserve it.

Authors: Moraru Vasile , Istrati Daniela , Zaporojan Sergiu
Published: January 2023

The purpose of this paper is the approach of a mathematical model dedicated to planning the consecutive days off of a company’s employees. Companies must find a flexible work schedule between employees, always considering the satisfaction of work tasks as well as guaranteeing consecutive days off. The analysis is based on solving a quadratic programming problem with binary variables. The proposed method uses the properties of the circulant symmetric matrix in the researched model, which allows the transformation of the considered problems into an equivalent separable non-convex optimization problem. A practical continuous convex relaxation approach is proposed. DC Algorithm is used to solve relaxed problems. A solved numerical example is presented.

Published: January 2023

Cornelian cherry (Cornus mas L.) is one of the most important forest fruits, considered as a valuable horticultural resource of bioactives, such as anthocyanins – cyanidin-3-glucoside, flavonoids, vitamins (e.g. vitamin C), carotenoids (e.g. β-carotene). The aim of this study was to obtain designed delivery systems of bioactive from cornelian cherry, as microencapsulated powders in order to assure their controlled release and to develop stable and natural additives for different application. Anthocyanin’s (concentrated extract) from cornelian cherry fruits were microencapsulated in a complex, biopolymeric matrice, formed by whey protein isolate (WPI) and pectin (PT). Two experimental variants were obtained by varying the ratio between WPI and PT, such as 1:1 (PT1) and 1:2 (PT2). The powders were tested for encapsulation efficiency of the anthocyanins, phytochemical profile of the extract and freeze-dried powders, as well as colorimetric analysis. Encapsulation efficiency of the anthocyanins varied between 80.04 and 82.11% with an important level of biologically active compounds (total polyphenols, total flavonoids) and remarkable antioxidant activity. Colorimetric analysis reveals a red colour of the powders, associated with their anthocyanin content. Both experimental variants proposed in this study protected the anthocyanins from cornelian cherry fruits. Moreover, microencapsulated powders can be used as natural food additives due to their red colour and phytochemical profile.
Analysis of Ore Hand-Crushed Size Distribution for Grinding Process in the Artisanal and Small-Scale Gold Mines Production: A Case Study of Nholi Mine, Bahi District
Authors: Tembo Malugu , Mdee Ombeni John
Published: January 2023

In many parts of the world, artisanal and small-scale gold mines (ASGM) employed numbers of people compared to large-scale mines. The ASGM has been played a crucial role in poverty alleviation and rural development, particularly in developing countries. The mined ore is crushed and ground for beneficiation of gold. The grinding process involved the size reduction of blasted materials to acquire minerals of interest. This paper presents the size distribution of hand-crushed for blasted materials using sieve analysis and digital image processing. The sieve test results for hand-crushed blasted material of three muck-piles were ranged between 17 mm and 36 mm that is equivalent to 20% and 80% passings respectively, with an average of 26 mm. The digital image processing results were about 19.8 mm for 20% passing and 58 mm for 80% passing, with an average of 36.06 mm. The hand-crushed provided a wide range of material distribution than the required size in the grinding unit and increased oversize by 18%. The hand-crushed of blasted materials provides different sizes distribution leading to increase the residence time and power consumption of the grinding units.

A History of the Beretta Model 1918 Moschetto Automatico
Authors: Clifford Frederick
Published: January 2023

This article aims to give an overview of the history of the Moschetto Automatico Revelli–Beretta (or Beretta Model 1918), an Italian self-loading carbine chambered for the 9 × 19 mm Glisenti cartridge. The author traces the developmental history of this weapon, from its conceptual forebears to its evolution from the twin- barrelled ‘Villar Perosa’ 9 mm machine gun. The adoption and service record of the Revelli–Beretta in the Italian Army is thereafter examined, following the path toward the weapon’s gradual obsolescence, and subsequent brief revival in the form of the improved Beretta Model 1918–1930 carbine. Finally, the use of the Revelli–Beretta outside of Italy is documented, and the weapon’s influence on arms design and its ties to the broader development of sub-machine guns in the interwar period is examined.

Published: January 2023

The food industry consumes large amounts of water although there is an increasing demand for water and a rapid decrease in the level of natural water resources. Wastewater resulting from food industries needs to be assessed for their compliance to standards. In this study, wastewater treatment steps from the food industry were investigated for accurate assessment of wastewater loading by analyzing parameters of the concentration of compounds present in the effluents. The results revealed that the parameters of treated wastewater were as follow, electrical conductivity 2931 μs/cm, total suspended solids 100 mg/L, biochemical oxygen demand 90 mg/L, chemical oxygen demand 250 mg/L, total phosphorus 7.9 mg/L, and total nitrogen 70 mg/L. This exerts a huge load on the biological treatment unit. Thus, this study offers an understanding and support in selecting appropriate treatment for industrial wastewater to obtain an effluent suitable in compliance with standards of the environmental quality.

Published: January 2023

Many researchers are attracted to Chitosan based blends due to its properties and potential applications in various fields. The advanced development of Chitosan blends integrates the science and technology of blended materials. The present experimentation is reporting the preparation of Chitosan and Agar-Agar blends (CCA) by chemical mixing of these materials at different compositions. The thermal studies of the prepared blends were studied by differential scanning colorimeter (DSC) and thermogravimetric analysis (TGA) tools. Thermal studies reveal that the lowest degradation temperatures of blends might be attributed to the partial miscibility of CAA blends at particular composition and miscibility due to single glass transition temperature (Tg) between Chitosan and Agar-agar. Bonding nature of sample blends were carried out by Fourier transform infrared (FT-IR) instrumentation. This study reveals the interaction between Chitosan and Agar-agar is partial miscibility. Morphological study reveals that a few aggregated particles, which suggest the partial miscibility of CAA blends. Homogeneity of blend compositions and specific intermolecular interactions of hydrogen bonding type is also observed.

Authors: Choudhury Anup , Nanda Jajneswar , Das Sankar Narayan
Published: January 2023

The purpose of this article is to investigate the effect of various process parameters such as compaction pressure, sintering temperature, and time on the physio-mechanical properties of a powder metallurgy-fabricated composite made of pure aluminium/alumina. Temperatures (580°C, 600°C, and 630°C), periods (1.5, 2, and 2.5 hr), compacting loads (30KN-65KN), and alumina percentages (2, 4, 6, and 8weight percent) are all considered. X-ray diffraction (XRD) and X-ray fluorescence spectroscopy (XRF) studies are carried out to determine the phases present and their proportions. Crystallite size study is performed using XRD data, and the Al+4 weight % alumina composite has the smallest size of any composite tested. For optimization, sintering density, porosity, and microhardness are calculated. Scanning electron microscopy (SEM) is used to analyse the different microstructures. At 600°C, 2 hr of operating time, and 4weight% alumina additions, the highest sintering density and microhardness are found.
Effect of peat, compost, and charcoal on transport of fipronil in clay loam soil and sandy clay loam soil
Authors: Fouad Mohamed Riad
Published: January 2023

This study used 30 cm long packed by 3 kg soil columns to explore the effects of peat, compost, and charcoal at 5% on the movement of fipronil (99.9 % purity) in clay loam soil and sandy clay loam soil. The soil columns were preconditioned with calcium chloride solution (0.01 M) before applying the pesticide and potassium iodide. Potassium iodide solution (0.2 M) was added at a rate of 10 mL as a water tracer and a quantity of fipronil solution (10 µg g-1soil) was applied on the soil surface of each column. Next, fipronil was leached from the soil columns with a calcium chloride solution (0.1 M) and the leachates were collected and analyzed. The results show that water tracer I- leached fast in soil columns. The breakthrough curve of fipronil appeared from leachates of soil columns after iodide for a while, indicating that fipronil is a moderate or lower mobile compound depending on type of soil and type of soil amendments. In general, adding soil amendments (peat, compost, and charcoal) to clay loam soil and sandy clay loam soil resulted in improved fipronil adsorption and decreased the amount of fipronil that leached into groundwater. This study is very useful for preserving groundwater from pollution, especially in the Middle East due to the lack of water sources.

Evaluating the Egyptian agricultural lands in terms of their capability and suitability for cultivation with different crops is necessary to reach the best benefit. Therefore, many researchers and specialists in the field of land evaluation follow several methodologies and apply different models to reach the most accurate results. Among those used methods, mathematical and statistical models are deal with many layers of data. On the other hand, computerized and automated models developed by software packages save time, effort and deal with a huge amount of data at one time. One of the most important tools currently used in presenting the results of land evaluation is the Geographic Information System (GIS) tools. These tools deal with spatial and soil attributes in the multiple sites to be evaluated. The main advantages of these tools are that they display data over a wide geographical scale in the form of spatial distribution maps. These maps are very important for decision makers in achieving better agricultural practices and optimal utilization of land resources. With the use of these tools, future planning for reclamation and cultivation of lands becomes clear and simple, in addition to saving costs significantly.

This study aimed to assess the effect of existing feeding system on milk yield and nutritional status and profitability of 75.0% and 87.5% Holstein crossbreed cows under existing farming system in an area of Bangladesh. In a milk pocket area (Keraniganj, Dhaka), three dairy farms termed F1, F2 and F3 were randomly selected having 34, 55 and 19 lactating cows, which 75% and 87.5% Holstein blood were 48 and 60, respectively. Using pretest questionnaire information like body weight, daily milk production, parity number, days in milking, blood percentage and feeding system of each animal were noted throughout a year. All data of three farms were subjected to analyze in one-way ANOVA in terms of 75% and 87.5% Holstein cows, separately. The body weight (kg) of 75% Holstein were F1 (296), F2 (497) and F3 (496) cows (p<0.05), while daily milk yield (kg) did not differ markedly among F1 (9.1), F2 (10.5) and F3 (13.9) (p>0.05), respectively. 75% Holstein of F1 offered almost, metabolizable energy (ME) and digestible crude protein (DCP), while cows of F2 and F3 fed daily insufficient DCP (-0.14kg) and over DCP (+0.47kg), respectively thus resulting in 37.2% less milk yield in F3 compared to F2 (p<0.05). Besides, 87.5% cows of F1, F2 and F3 had 365, 528 and 566kg body weight (p<0.05) and daily produced 10.5, 10.8 and 19.4kg milk (p>0.05), respectively. However, 87.5% cows of F1 daily offered almost balance ME and DCP, while the cows of F2 fed lower DCP (-0.2kg). Then, cows of F3 daily fed excessive DCP (+0.14kg) thus resulting in produced 8.6kg higher milk than cows of F2. Net return except depreciation cost from 75% cows of F1, F2 and F3 were 118, 170 and 145BDT, while 87.5% cows of F1, F2 and F3 were 189, 196, and 413BDT (p>0.05), respectively. It may be concluded that under existing feeding system and farming practices, cows from the F1, F2, and F3 of 75% and 87.5% Holstein blood daily produced 9.8, 10.7 and 16.7kg of milk per day with 330, 512, and 531kg body weight on average, generating 154, 183, and 279BDT in profit, respectively. Feeding lower nutrient to dairy cows resulted better milk yield and return at the sacrifice of cow fitness, while excessive feeding lead to higher milk yield but lower return, whereas optimum nutrition resulted in better milk yield and return.

Resumo: O percevejo barriga-verde, Dichelops furcatus (Fabr.) (Hemiptera: Pentatomidae), é uma praga-chave da cultura do milho, que causa o danos tanto pela sucção de seiva quanto pela injeção de toxinas que afetam o desenvolvimento normal das plantas. Para estabelecer o nível de dano econômico (NDE) dessa praga na cultura do milho, foi instalado, em janeiro de 2014, um experimento no campo, em Chapecó, SC, adotando delineamento em blocos aleatorizados. Os tratamentos foram com diferentes níveis populacionais (0, 2, 4, 8 e 17) de percevejos adultos, liberados em gaiolas com 12 plantas de milho (unidades experimentais). As avaliações constaram da contagem do número de plantas sintomáticas após 25 dias da emergência das plantas e a produtividade de grãos. O aumento do nível populacional de D. furcatus ocasiona crescimento linear no número de plantas sintomáticas e redução significativa na produtividade. O NDE para D. furcatus na cultura do milho situa-se sempre abaixo de 0,5 percevejo por metro de plantas em cenários de preço do milho variando de R$12 a R$36 a saca de 60kg e custo de controle da praga variável entre R$40 e R$160 por hectare.

Objective: To evaluate the diagnostic validity of Sonosalphingography as a tubal patency test in infertile women using laparoscopy as gold standard. Methodology: This study was carried out at the Shifa International Hospital Islamabad, and the duration of this study was from January 2021 to June 2021. We used the WHO method for sample size by taking the prevalence of tuboperitoneal factors as 30%, sensitivity 72.9%, specificity 81.22%, margin of error 12%, and 95% confidence interval. It was a cross-sectional study that lasted for 6 months and assessed a total of 178 patients. Additionally, a non-probability, sequential sampling strategy was utilized to acquire the sample. Results: Our patients aged between 18-45 years, out of which 30% of the participants aged 18 to 25 years, 55% were between 26 and 35 years, and 15% were between 36 and 45 years. Standard deviation was 1.26, with a mean age of 27. The data collected from both the diagnostic tests was analyzed, diagnostic accuracy of Sonosalphingography was calculated as a sensitivity of 81%, specificity of 76%, positive predictive value of 90%, negative predictive value of 60%, and diagnostic accuracy of 79%. Conclusion: According to the results of our study, Sonosalphingography is a very helpful supplemental diagnostic tool for evaluating tubal disease in patients with infertility, though direct laparoscopic assessment is the gold standard. Sonosalphingography and laparoscopy can be used to evaluate patients with secondary infertility. This spares the patient from being exposed to radiations and the discomfort of contrast administration in HSG.
