Selenium deficiency, toxicity and its requirement in marine fish: A research review
Authors: Pham Duc Hung
Published: February 2024

The necessity of selenium (Se) in maintaining normal growth and physiological functions have been demonstrated in fish due to its important role as a cofactor in glutathione peroxidase enzyme (GPx), protecting cell membranes against oxidative damage. The deficiency of Se can lead to reduced growth, feed utilization and health status in farmed fish. Whereas fish fed elevated dietary Se levels results in reduced feed utilization and adverse effects on physiological performance and impaired histology. Dietary Se requirements have been quantified for some marine fish species with varied results, probably due to the differences in bioavailability, sources of Se, protein ingredients as well as the interaction of Se with other nutrients in the diets. Besides, due to the narrow gap between deficiency, optimality and toxicity of Se level, it is imperative to find out the exact dietary Se requirement for any aquatic species. This review summarizes the available information regarding dietary Se requirements in marine fish. The effects of Se deficiency and its toxicity in marine fish also are discussed.

Effect of Irrigation Intervals, Irrigation Method and Different Nitrogen Fertilizer Rates on Wheat Performance and Water use Efficiency in Northern State of Sudan
Authors: Mohammed Ali Abdalla
Published: February 2024

Most soils under arid conditions have extremely low quality due to poor physical conditions, low organic matter and water retention capacity, soil fertility and consequently both low water and fertilizer use efficiencies. The present study was planned to investigate the effects of irrigation interval (II), irrigation methods (IM) and nitrogen fertilizer rates (NF) on wheat performance (yield and its components) and water use efficiency. The experiment was conducted at National Institute of Desert Studies Research Farm for two consecutive winter seasons of (2020/21) and (2021/22) in a sandy soil of North Sudan. The experiment design was complete randomized block in factorial arrangement with four replications. Factor (A) was irrigation methods with two types (furrow and basin), factor (B) was irrigation interval with three rates (7, 10, 13 days) and factor (c) was assigned to nitrogen with three rates (43, 86 and 129 Kg/fed). The results showed that irrigation methods had not significant p (≤.05) effect on wheat yield and its components and water use efficiency, irrigation interval affected significantly p (≤.05) on plant height, biomass, spike per meter square, grain yield and water use efficiency in both seasons Nitrogen fertilizer were effective highly significant p (≤.05) in improving biomass p (≤.05) and significantly p (≤.05) effect on plant height, number of spike per meter square, grain yield and water use efficiency in both seasons. Both irrigation interval and nitrogen fertilizer rates were not significant p (≤.05) effect on plant per meter. Maximum yield and high water use efficiency were obtained when irrigated every 7 days and added nitrogen fertilizer in rate of 129 Kg per fedan.
Role of Weather Parameters on Quality Seed Production
Authors: Narayanan AL
Published: February 2024

Weather and climate are important factors deciding the growth of any crop. Meteorologists and seed technologist view the weather as a dominant element influencing yield and acreage behaviour of crops. The meteorological inputs, unlike other inputs such as land, labour, high-yielding variety (HYV) seeds, fertilizers, pesticides, etc. is a direct input in seed production. The functional relationship between weather and yield is as much complicated as the term ‘weather’ itself. Occurrence of abnormal weather episodes during the growing season or during critical development stages may hamper growth processes resulting in yield reduction. Optimum temperature is the balanced heat requirement for the crop since lower or higher temperature results in abnormal effect of the crop growth. When the temperature goes below the minimum or the base level it is said that the physiology will be reduced or even nil. Similarly, when the temperature goes above the maximum the metabolic activity is enormous leading to the scorching or burning effect. The range of wavelength is a part of electromagnetic spectrum of the radiant energy which includes short wave, x-rays and g rays, long radio waves. The electromagnetic spectrum comprises of U-V, visible, IR wavelength which together transmits 90% of energy. Precipitation in any forms say rainfall, snow, fog, mist, dew, etc is important for the crop growth in relation to the seed production. Because the requirement of water for a plant growth is fulfilled naturally by precipitation. However, the effect is more contemplated in tropical countries like India. Amount of water vapour present in the atmosphere at a given time to the same atmosphere under saturation is termed as relative humidity. The VPD namely Vapour Pressure Deficit which is the difference between the pressure exerted by an atmosphere at a given condition to the same at atmosphere at hundred per cent saturation. That means the VPD is the prime cause for the transpiration of the crop plants. Seed production in efficient manner is a challenge in today’s context in correlation to weather parameters. The sowing window is to be adjusted accordingly so that all the growth phases coincides with favourable weather conditions and the crop is having an opportunity to produce quality seeds. The farm shall have wind breaks and shelter belts to enable suitable microclimate for crop production. Weather cannot be changed but managed by knowing before its occurrence termed as weather forecasting.

The development of crop specific sustainable management practices under changing climate is continuous process. Hence, effort has made to describe some of the sustainable management (conservation agriculture, integrated crop management, organic farming and natural farming) practices in rainfed soybean to enhance productivity, restore soil fertility and farm profitability under changing climate.
Fart for Fart's Sake? The Fantastical Reality, Sacred-Profane Musical Bodies, and Nostalgic Millennial Masculinities in Swiss Army Man
Authors: Pääkkölä Anna-Elena , Burditt Rebecca
Published: February 2024

This article explores the uses of music, voice, and sound in Daniels’ 2016 film Swiss Army Man (SAM)—a story about a friendship between a stranded, suicidal loner (Paul Dano) and a farting, talking corpse (Daniel Radcliffe). We argue that the film's unique play between nondiegetic and diegetic sound, musical references to popular culture, and privileging of bodily noise (particularly farting) generate a distinctive soundscape that adds new dimensions to SAM's major themes of loneliness and nostalgia. This study draws upon scholarship in musicology, film studies, social history, and queer studies to better define the sonic techniques that the directors and composers employ. In doing so, it also helps us locate how sound articulates the film's genre, its construction of masculinity, and the queerness of the two protagonists’ relationship. Our goal is to provide insight into a film in which farting equals music, and meaning is made through colliding dualities: sacredness vs. vulgarity, a hyperbody that is both dead and alive, heterosexual yearning vs. homoromantic bonding, and even comedy vs. tragedy.

Published: February 2024

In the design of advanced gas turbines, improving thermal efficiency and power output is crucial achieve energy saving and emission reduction goals. This necessitates raising the inlet temperature, thereby highlighting the importance developing efficient cooling technologies to ensure the longevity of hot components. Gas film cooling, as a widely used traditional cooling method, is subject to the influence of fluid dynamic characteristics, especially in unstable operating environments such as pressure fluctuations in the upstream combustion chamber and interactions between stators and rotors. This study utilized large eddy simulation to analyze the effectiveness of trench film cooling under such unstable conditions, with a specific focus on the time-averaged and transient characteristics of forward and backward injection of cooling air. The study investigated the efficacy of film cooling under pulsating flow conditions, with a blowing ratio of 1.5 under steady-state conditions, utilizing cosine and square waves as pulse boundaries, and a Strouhal number of 0.254. The research findings reveal that: 1) Contrary to the results under steady-state conditions, pulsating reverse injection led to a reduction of over 15% in time-averaged cooling efficiency and a noticeable decrease in the film coverage area compared to forward injection; this phenomenon is determined by the different flow mechanisms under steady-state and pulsating states. 2) Under a certain blowing ratio, the instability of gas film cooling is induced by the temporal fluctuations of near-wall vortices, which could result in rapid temperature changes and component failures. For pulsating forward injection, additional high film cooling unsteadiness outside the slot membrane orifices was observed. In the case of backward injection, pulsations did not lead to a significant increase in instability. These research findings provide a deeper understanding of the impact of gas film cooling on the cooling efficiency and stability of gas turbines, enabling gas film cooling technology to meet the inlet temperature requirements of advanced gas turbines, thereby reducing carbon emissions and contributing to the achievement of China's dual carbon goals.

Ho boulomenos and Athenian public lawsuits from the death of Alexander the Great to the first century B.C.: evidence of the survival of a classical legal institution in Hellenistic Athens
Authors: Filias Dionysios
Published: February 2024

The practice of granting any willing individual the right to denounce serious offences has been directly linked to the legal system of Athens. Although the literary and epigraphic material concerning the law of post-classical Athens is less informative than that of the classical period, references to procedures initiated by ho boulomenos (“anyone who wishes”) from the late fourth century B.C. to the early years of Augustus’ reign show that the Athenian legal system continued to provide for the right of volunteers to denounce offences affecting important aspects of social and political life, such as acts against the polis constitution, religious affairs or the use of proper weights and measures. This article highlights the phenomenon of public lawsuits in Athens during the Hellenistic period by presenting all relevant literary and epigraphic references and demonstrating the continuing importance of this type of prosecution for the Athenian state.
Does assisted reproductive technology has effect on human secondary sex ratio?
Authors: Elhddad Agzail S. , Younis Faiza M.
Published: February 2024

assisted reproduction technology (ART) is up-trending, therefore number of babies born by ART is increasing. ART may influence the secondary sex ratio (SSR) compared to natural conception. to evaluate the effect of ART on SSR. a pilot retrospective medical records review study was conducted on 201 live-birth babies born to couples attended Albayda Fertility Centre. 97 babies were born by ART procedures [intrauterine insemination (IUI) and intracytoplasmic sperm injection (ICSI)] and the remaining were born by non-ART (medical treatment or post-hysteroscopy). The overall SSR was 46%, SSR for non-ART babies was (54.8%) higher than that for the ART offspring (47.4%), however, the difference was non-significant. More girls were born as a result of ICSI (SSR= 43.7%). In contrast, more males were born following IUI (SSR=47.7%) but the difference was insignificant. Regarding the stage of embryo transfer (ET) in babies born by ICSI, a higher but a non-significant difference (Fisher’s Exact test = 0.9) was found in blastocyst stage than the cleavage stage. ART might cause a bias in sex ratio at birth and this change in SSR was found to be affected by the ART procedure applied. The mechanism of these effects is still controversial, larger and multi-centric studies are still warranted.

Published: February 2024

Baja AISI 4140 banyak digunakan pada industry permesinan ataupun banyak digunakan pada komponen otomotif. Pada penelitian ini dilakukan uji kekerasan dan uji struktur mikro dari baja AISI 4140 dengan pelapisan Ni-Cr dan dilakukan metode sputtering. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh dari lapisan Ni-Cr terhadap kekerasan dan stukrtur mikro dari baja AISI 4140. Teknik sputtering dilakukan dengan deposisi waktu 60, 90 dan 150 menit. Dari hasil pengujian tersebut, pada pengujian kekerasan dengan waktu 60 menit kekerasannya 137,84 HVN, 90 menit 163,96 HVN dan 150 menit kekerasannya menurun menjadi 161,7 HVN. Ini disebabkan karena laju deposisi terlalu besar tetapi difusi dan reaksi atom nitrogen (N) dengan substrat (unsur komposisi lain) tidak dapat mengikuti maka dimungkinkan akan terjadi penumpukan atom nitrogen pada permukaan, sehingga menyebabkan kekerasan permukaan tidak naik melainkan akan turun. Untuk pengujian SEM/EDX dapat membuktikan bahwa lapisan Ni-Cr dapat terlihat dengan terang dibandingkan dengan substrat baja AISI 4140 yang cenderung gelap warnanya.

Ragum merupakan alat mekanis yang biasa digunakan untuk memegang atau mencekam benda kerja dengan memanfaatkan poros ulir untuk membuka dan menutup rahang cekam. Penggunaan ragum pada proses pemesinan, penggergajian, pengeboran, dan penggerindaan. Salah satu jenis ragumyang dibutuhkan pada masa kini ialah ragum dengan aksis banyak (multiple axis bench vise). Pada penelitian ini dilakukan analisis desain ragum kerja bangku 3 aksis (2 aksis rotasi dan 1 aksis translasi) dengan metode elemen hinga. Desain ragum dibuat menggunakan Autodesk Inventor, dengan bukaan rahang 5 inchi, lebar rahang penjepit 5 inchi, dan kedalaman bukaan rahang 3.25 inchi. Material ragum ialah besi cor FC 25. Variasi desain ragum ialah pada ketebalan bagian rahang gerak yang bersinggungan dengan rahang tetap. Gaya cekam dihitung berdasarkan spesifikasi poros transportir. Simulasi elemen hingga menggunakan Simulia Abaqus. Hasil simulasi ialah tegangan Von Mises, yang akan dibandingkan dengan tegangan luluh besi cor FC 25 untuk menghasilkan nilai faktor keamanan. Faktor keamanan desain ragum multi aksis ketika beban statis diterapkan. Seluruh tegangan maksimum dari variasi desain bernilai diatas nilai tegangan luluh material ragum. Hasil tersebut berdampak pada nilai faktor keamanan, yaitu dibawah nilai 2. Berdasarkan nilai faktor keamanan yang dihasilkan, ragum tidak aman dari deformasi plastis. Sehingga perlu adanya pengkajian ulang desain atau material yang digunakan.

Kaki palsu merupakan salah satu alat bantu yang direkayasa sebagai peniru fungsi dari kaki pada umumnya. Produk kaki palsu yang beredar di Indonesia mayoritas produk impor dan terbuat dari material stainless steel, namun harga dan biaya produksi manufakturnya relatif tinggi. Berdasarkan pemaparan tersebut, perlu diinisiasi material lain agar kaki palsu lebih terjangkau. Salah satu material yang bisa digunakan ialah aluminium. Pada penelitian ini akan dilakukan studi kekuatan mekanis peleburan alumunium piston bekas. Aluminium bekas berasal dari piston bekas kendaraan besar (bus atau truk). Sifat mekanik didapatkan dari hasil uji tarik yang mengacu pada ASTM E8/E8M – 13a. Peleburan untuk pembuatan spesimen uji tarik dan uji komposisi menggunakan krusibel grafit. Tiga spesimen dicetak menggunakan cetakan pasir dengan metode closed mold casting. Acuan kelayakan aluminium piston bekas sebagai alternatif material ialah kekuatan luluh hasil peleburan harus lebih besar dari tegangan maksimum pada kaki palsu yaitu sebesar 153 N/mm2. Berdasarkan pengujian, kekuatan tarik dan kekuatan luluh rata - rata ialah 121,51 N/mm2 dan 51,78 N/mm2. Hasil peleburan aluminium piston bekas belum bisa digunakan sebagai material kaki palsu, karena kekuatan luluh yang merupakan salah satu acuan untuk pemilihan bahan, lebih rendah dari tegangan maksimum yang terjadi. Sifat mekanis yang rendah disebabkan oleh tingginya kandungan unsur Fe yaitu sebesar 0,85%, dimana kandungan unsur Fe lebih dari 0,6% akan menurunkan kekuatan tarik dan kekuatan luluh aluminium paduan. Lebih dari itu, hasil peleburan aluminium piston bekas tergolong material getas, karena nilai elongasinya dibawah nilai 5%.

Authors: Omrane Amina , Khan Mohammad Ayub
Published: February 2024

The present study represents a comparative analysis between the national cultures of six countries: Tunisia, Germany, China, Mexico, Pakistan and the USA. The overall results of this analytical research indicated that in the light of the Hofstede’s model foundations, Tunisia, Pakistan and Mexico resemble each other to a great extent. Indeed, even if they are geographically far from each other and residing in three different continents, their corresponding national cultures based on religious values, social organization, and language seem similar. Conversely, Germany, China and the US share similar cultural features, even if China is known by its collectivism. Such findings offer cross cultural opportunities and challenges for business leaders and entrepreneurs who are willing to do business in these countries.
