Authors: Benyagoub E. , Lali M. Ahmed , Lamari N.
Published: April 2022

Background: Meat is the first source of animal protein, its richness in essential amino acids classifies it among the noble proteins. However, due to its nutritional qualities, meat constitutes a favorable ground for microbial development and can serve as a source of foodborne pathogens for consumers. Hence this study aimed to evaluate the hygienic quality of fresh camel meat marketed in Bechar city (Southwest of Algeria). Methods: At the butcher’s shops in the Bechar El Djadid’s market, the taken samples underwent analyzes of a few physicochemical and microbiological parameters. The suspected pathogenic isolates were confirmed using biochemical tests. Result: The physicochemical parameters results showed that the samples had slightly acidic pH values ranging from 5.25 to 5.86, the temperature from 6 to 7.5°C and the total solid content (TSC) ranging from 21 to 36.6% with a moisture rate ranging from 63.4 to 75.6. However, the obtained microbiological results showed a load of Escherichia coli of 3.3 and 4.83 Log10 CFU/g for the samples S1 and S2, respectively, exceeding the threshold set by national standards. The analyzed samples had a load of S. aureus (CoPS) ranging from 3.78 to 5 Log10 CFU/g, with the presence of Salmonella choleraesuis ssp arizonae for the sample (S1), while both Listeria monocytogenes and Pseudomonas spp species were absent in all the analyzed samples. The lactic acid bacteria (LAB) load ranged from 2.36 to 2.74 Log10 CFU/g. In conclusion, four out of five analyzed samples had an unsatisfactory quality.

Authors: Kumar Sushil , Yadav Bikram , . Akshit , Kamboj Ekta , Sharma Kartik , Devi Priyanka , . Shalu
Published: April 2022

Background: Clusterbean is one of the most important crop of arid and semi-arid region of India. It is mainly grown for vegetable, manure, fodder and seed purpose. Seeds of clusterbean contain galactomann (stored in endosperm) which has industrial uses, thus making it the major cash earner crop. Various biotic and abiotic stresses affects the crop during its growth stages. Among biotic stresses, weeds are the major one affecting the crop growth and yield. Due to initial slow growth of the clusterbean intense crop-weed competition takes place upto 20-30 DAS and if weeds are not managed properly there will be a severe yield reduction. Under Haryana conditions only manual weeding is recommended which is time consuming and expensive hence there is need to exploit other methods of weed control. Therefore, present study was conducted to study the effect of mechanical methods of weed management on growth, yield and economics of clusterbean. Methods: A field experiment was conducted during kharif season 2018 to study the effect of mechanized weed management practices on growth, yield and economics of clusterbean at Regional Research Station, Bawal (Rewari), CCS Haryana Agricultural University, Hisar. Experiment was performed in randomized block design with ten treatments and three replication. Result: It was found that among various weed management practices, two mechanized weeding with power weeder at 20 DAS and 35 DAS under 60 cm row spacing resulted in significantly higher plant height, leaf area index, dry matter accumulation, seed yield and its attributes in comparison to other treatments and it was statistically at par with mechanized weeding at 20 DAS and 35 DAS with tractor drawn cultivator. The weeding with tractor drawn cultivator was found to be most economical with maximum net returns (Rs. 36076 ha-1) and B:C (2.37) in comparison to other treatments followed by weeding with power weeder that fetched net return of Rs. 35868 ha-1 with B:C of 2.25. Therefore, two times interculture with power weeder or tractor drawn cultivator found beneficial and economical for farmers.

Euthanasia: Domestic and Foreign Experience of Legal Regulation
Authors: Eliseeva G. V.
Published: April 2022

The article discusses various approaches to the premature discontinuing of the life of a terminally ill patient both at the state and international level. The purpose of this study is to revise the previously established approach to the use of euthanasia in the Russian Federation. A different view of the use of euthanasia is necessary, among other things, because in some cases, only the premature termination of a person's life may be the only way to end his suffering from a vain struggle with an incurable disease. The difficulties associated with the use of the euthanasia procedure over a long time period are a topic of discussion for many scientists. The relevance of this topic is emphasized by the rapidly changing views on the possibility of using euthanasia from an ethical point of view. More and more international organizations are expressing their own views on euthanasia and assisted suicide. As for the legal order of individual states, there is a tendency to use one of three approaches to ending the suffering of a patient by causing death: the first approach is characterized by a prohibition on the use of euthanasia under the threat of criminal punishment and qualifying such an act as murder in the absence of a special corpus delicti; in the second approach, euthanasia is also a criminal offense, however, the criminal law of states using this approach establishes a special offense that provides for a milder punishment than murder; in the third approach, the law provides for the right to use euthanasia. The article provides a comparative analysis of the euthanasia procedure used in Belgium and the assisted suicide procedure used in Switzerland. In addition, the point of view of the European Court of Human Rights on the issues under consideration is given. The main research method is the analysis of scientific literature on the research topic, the analysis of normative acts of domestic and foreign legislation, a comparative analysis of the legal order of states that carry out various approaches to the application of the euthanasia procedure.

Authors: Shastouskaya S. A.
Published: April 2022

The article discusses the formation and development of the legislation of the Republic of Belarus in the field of nuclear waste management, gives a description of the main trends in its development. The legislation of the Republic of Belarus in the field of nuclear waste management establishes requirements for the procedures for selecting sites for the placement of facilities where radioactive waste is handled, requirements for the design, construction, operation and closure of these facilities, as well as for conducting a safety assessment of the relevant facilities. Legal regulation in this area should be developed in such a way that the negative impact on the environment is minimized and the environmental rights of everyone are protected. On the basis of the Author’s approaches, the periodization of the regulatory legal framework of the study area is distinguished. The following stages of the formation and development of legislation in the field of nuclear waste management in the Republic of Belarus have been identified: Stage 1 – Soviet (1954–1985); Stage 2 – Chernobyl (1986–1991); Stage 3 – post-Soviet (1992–to the present), having their own characteristics characteristic of the corresponding period. This division is historically conditioned, since the influence of historical facts was reflected in the development of legal regulation in the field of nuclear waste management. It is also noted that the establishment of a clear delimitation of the competence of the Ministry of Emergency Situations and the Ministry of Health in establishing regulatory regulation in the field of nuclear waste management will improve the quality of legal regulation, and will help ensure the systematization and codification of the legislation of the area we are studying. It is concluded that it is necessary to improve legislation in the field of nuclear waste management in close cooperation between representatives of science, through the exchange of scientific and technical information (best practice), which is an important element of scientific, legal, economic and technical development.

Published: April 2022

Electrical energy is a very important requirement for human life. The supply of electrical energy itself consists of electricity generation, power transmission and distribution. In the distribution of electricity, there are several networks that function to distribute electrical energy to customers, the majority of which are network configuration, namely radial and loop. In order to maintain the continuity of the distribution of electrical energy, a good level of reliability is required. In order to determine the reliability of the distribution system, the reliability index is determined, namely SAIFI, SAIDI and CAIDI. Several methods that can be used to find a distribution system reliability index include the RIA (Reliability Index Assessment) method, which is an approach used to predict disturbances in a distribution system based on the system topology and data regarding component reliability. In this study, we compared two configurations using one feeder, namely the Giri feeder which is assumed to have a radial configuration and a loop configuration. By using the RIA (Reliability Index Assessment) method on a Giri feeder with a radial configuration, the SAIFI reliability index is obtained at 1.595 times / year, SAIDI is 12.8092 hours / year, CAIDI is 8.0309 hours / year, while for a feeder with a loop configuration the SAIFI value is equal to 1,651 times / year, SAIDI is 1,7276 hours / year, CAIDI is 1,0416 hours / year.

Authors: Yaqin Feridad Ainul , Rahmawati Diana , Ibadillah Achmad Fiqih , Wibisono Kunto Aji
Published: April 2022

Power supply merupakan perangkat keras yang mampu menyalurkan tegangan listrik secara langsung dari sumber tegangan listrik PLN ke tegangan listrik yang lainnya. Peralatan power audio memerlukan power supply yang berdaya yang besar untuk menghasilkan suara yang besar dan tegangan drop yang rendah sehingga dapat memaksimalkan penggunaan energi listrik untuk konsumsi power audio. Power Supply Switching pada umumnya memiliki kekurangan seperti tegangan drop yang tinggi ketika dibebani, serta kurangnya tingkat efisiensi yang disebabkan tidak adanya rangkaian Power Factor Correction  (PFC), sehingga membuat faktor daya pada input power suplay rendah dan mengakibatkan output tidak maksimal. Pada penelitian ini membuat rancangan  Power Supply Switching yang akan dioptimalkan menggunakan topologi half bridge converter dan rangkaian PFC. Pada rangkaian PFC menggunakan IC FA5502 dengan Frekuensi 125 Khz lalu di serahkan dengan menggunakan dioda frekuensi tinggi dan di filter menggunakan kapasitor. Hasil penyerahan masuk ke half bridge converter mengunakan mosfet IRFP 460 dan dikontrol menggunakan IC SG3525 dengan frekuensi switching 79 KHz. Kemudian masuk ke trafo frekuensi tinggi untuk di konversikan ke tegangan rendah, setelah itu disearahkan menggunakan dioda frekuensi tinggi dan masuk kedalam rangkaian filter kapasitor. Power supply ini juga dilengkapi dengan rangkaian proteksi hubung singkat, sehingga jika terjadi hubung singkat maka power supply akan shut down. Dengan rancangan ini didapatkan bahwa power supply yang di buat memiliki drop tegangan yang rendah ini disebabkan karena adanya rangkaian feedback yang meregulasi tegangan outputnya serta terdapat proteksi hubung singkat untuk  mengamankan power supply dan power amplifier yang di supply jika terjadi hubung singkat.

Published: April 2022

Meningkatnya penggunaan kendaraan konvensional yang menggunakan bahan bakar fosil berdampak pada lingkungan. Salah satu solusi dari masalah tersebut yaitu dengan merubah mesin penggerak utamanya dari motor bakar yang berbahan bakar fosil menjadi motor listrik. Tujuan dari penelitian ini untuk mengetahui pengaruh perbedaan magnet terhadap kinerja motor BLDC. Pada penelitian ini menggunakan magnet neodymium dengan penampang berbentuk persegi dengan ukuran 15 mm x 15 mm x 5 mm dan 10 mm x 10 mm x 2 mm. Pengujian pada penelitian ini juga dilakukan dengan memberikan variasi tegangan sumber sebesar 11 V hingga 24 V. Metode pengumpulan data pada penelitian ini menggunakan dua cara yaitu dengan pengukuran dan perhitungan. Dari pengukuran didapat data berupa nilai arus sumber, Vpp, frekuensi, dan kecepatan motor. Sedangkan dari perhitungan, didapat data berupa nilai tegangan motor, arus motor, daya input, daya output, efisiensi daya, kecepatan hitung, error persen kecepatan, dan torsi motor. Pengujian pada penelitian ini dilakukan sebanyak empat kali. Dari keempat pengujian yang dilakukan, pengujian dengan hasil performa motor terbaik terdapat pada pengujian motor BLDC 3ϕ axial flux ketika nilai tegangan sumber dan frekuensi berbeda. Pada pengujian motor BLDC 3f axial flux saat tegangan sumber dan frekuensi berbeda, semakin besar variasi tegangan sumber dengan nilai frekuensi yang semakin besar pula, maka nilai torsi dan efisiensi daya pada kedua motor semakin kecil. Namun untuk nilai kecepatan semakin besar. Sedangkan untuk nilai daya output pada motor BLDC 3ϕ axial flux dengan magnet 15 mm x 15 mm x 5 mm semakin naik dan pada motor BLDC 3ϕ axial flux dengan magnet 10 mm x 10 mm x 2 mm semakin kecil. Untuk nilai torsi dan daya output pada motor BLDC 3ϕ axial flux dengan magnet 15 mm x 15 mm x 5 mm lebih besar dibanding pada motor BLDC 3ϕ axial flux dengan magnet 10 mm x 10 mm x 2 mm. Tetapi hal ini berkebalikan untuk nilai kecepatan dan efisiensi daya.

Descritivamente, sentenças panquecas têm duas características centrais nessa língua: (i) um nome na posição de sujeito, com uma estrutura menor do que um DP, recebe uma interpretação de situação; (ii) o predicado não concorda morfologicamente com esse sujeito. Um exemplo disso é a sentença Panqueca é bom. Estudos recentes (SIQUEIRA, 2017, SIQUEIRA; SIBALDO e SEDRINS, 2020) defendem que sentenças panquecas podem ter artigos definidos, como em A panqueca é bom. Mostramos que sentenças como A panqueca é bom são, na verdade, casos de elipse de parte do VP. Elas só são gramaticais caso tenham identidade com o antecedente e não são possíveis caso o antecedente seja só pragmático, isto é, caso o antecedente não tenha material linguístico. Em contraposição, sentenças panquecas, tais como tradicionalmente descritas, são possíveis em casos de antecedente pragmático e possuem, portanto, anáforas profundas em sua constituição. Quando os dois tipos sentenciais são examinados à luz da classificação em termos de anáfora superficial e anáfora profunda, evidencia-se que sentenças panquecas exemplificadas por Panqueca é bom têm uma constituição diferente de sentenças com elipses verbais, como A panqueca é bom. Dessa forma, mostramos que só a primeira se configura como uma verdadeira sentença panqueca.

HIGHLIGHTS
1. Pregnancy with preeclampsia in this study was mostly terminated by cesarean section. A small percentage was with vaginal delivery.2. Most preeclamptic mothers gave birth by cesarean section exhibited severe symptoms of preeclampsia, such as severe hypertension, severe proteinuria, and visual impairment.
 
ABSTRACT
Objectives: To determine the symptoms of pregnant women with preeclampsia through the method of pregnancy termination.
Materials and Methods: This study used a cross-sectional method for descriptive analysis. The total sample included 75 pregnant women with preeclampsia. The sampling techniques was carried out with purposive sampling. This study used auxiliary data in medical records of preeclampsia mothers who gave birth at Taman Husada Regional Hospital, Bontang, Indonesia, in 2019.
Results: The results showed that most preeclampsia mothers delivered by cesarean section (CS). Among mothers who gave birth by cesarean section, there were severe symptoms of preeclampsia, 74.14% had severe hypertension with systolic blood pressure of > 160 mmHg or diastolic blood pressure of > 110 mmHg.

Purpose - The concept of tourism as an experience is gaining interest among practitioners and academics alike. This study contributes to the tourism literature by integrating the antecedents and outcomes of memorable tourism experiences (MTE) and consumer-level factors as moderators into a single model. Design - The study applies primary survey using structured questionnaire. The study hypotheses are empirically tested based on survey data of 700 tourists (both domestic and foreign) in India. Methodology - The data collected is analyzed using structural equation modeling. The model also includes the moderating role of tourists’ openness to experience. Findings - Findings show a positive impact of destination attributes on MTE. MTE is observed to positively affect its immediate outcomes, perceived value and satisfaction from tourism experiences. Subsequently, satisfaction has a positive effect of loyalty and word of mouth (WOM), but perceived value affects only on word of mouth. Openness to experience moderated the impact of destination attributes on MTE. Originality - The study makes new theoretical and managerial contributions. The study is one of the first of its kind to integrate the antecedents and outcomes of MTE in a single study. Moreover, the study also considers the moderating influence of tourist personality in the same study.

Clay minerals are among the world’s most important and useful industrial minerals. Conductance, transmissivity and corrosity are some physical parameters for determining quality clay. Four (4) clay deposit sites in Kaffin-Koro, Dutse, Dogon-Ruwa and Kushikoko were investigated to evaluate corrosivity, the longitudinal conductance and transmissivity to determine the clay quality. Electrical resistivity method employing Schlumberger electrode array was used to determine the thicknesses and depths of the subsurface strata while Interpex 1xD software was used to interpret the data. Three (3) to four (4) layer earth models were delineated. Kaffin-Koro and Dutse showed three layer models while Dogon-Ruwa and Kushikoko revealed four layers. Moderate clay content was found in Kaffin-Koro in the second layer with longitudinal conductance value of 0.4780 siemens and thickness 0.770m at depth of 1.17m Dogon-Ruwa also had moderate clay content in the third layer with conductance value of 0.237 siemens, depth of 2.43m and thickness 1.76m. Kushikoko had low clay deposit in the second layer with conductance 0.1810 siemens and thickness 2.73 m at 4.37 m while the clay deposit in Dutse appeared to be generally poor as the longitudinal conductance values of the top two layers were less than 0.1 siemens.

Published: April 2022

Tsunami yang didasari oleh kejadian gempa bumi dapat menyebabkan kerusakan yang serius untuk penduduk wilayah pesisir pantai, terutama yang berada dekat dengan pusat gempa. Merujuk pada kejadian tsunami yang terjadi pada tahun 2004, pemerintah mulai mencanangkan pentingnya mitigasi untuk melindungi daerah pesisir pantai. Daerah Pesisir Barat Lampung merupakan daerah yang berbatasan langsung dengan lempeng Eurasia. Hal ini dapat menjadi salah satu pemicu kemungkinan terjadinya gelombang tsunami pada Pesisir Barat Lampung. Tujuan dari penelitian ini yaitu untuk memperlihatkan potensi penjalaran gelombang tsunami di daerah Pesisir Barat Lampung. Simulasi yang dilakukan dalam kajian ini meliputi dua tahapan: 1) simulasi dari penjalaran gelombang gempa dengan menggunakan data gempa pada tahun 2019 (magnitudo 5,1 di area sekitar Pesisir Barat Lampung) dan dengan mengasumsi magnitudo gempa sebesar 6,0; 7,0 dan 8,0 (simulasi dilakukan dengan menggunakan metode deformasi), 2) Simulasi penjalaran gelombang tsunami dengan menggunakan TUNAMI Modified (beta version). Berdasarkan hasil simulasi, penjalaran gelombang tsunami dengan magnitudo 5,1 tidak mencapai garis pantai pada daerah Krui dan Bengkunat. Sedangkan untuk gempa dengan magnitudo 8,0 menghasilkan gelombang sebesar 1,14 meter pada garis pantai Bengkunat. Walaupun penjalaran gelombang pada gempa 5,1 tidak mencapai garis pantai, namun perlu adanya simulasi potensial penjalaran gelobang tsunami untuk magtitudo gempa yang lebih besar guna pengambilan keputusan dalam penentuan mitigasi bencana di daerah Pesisir Barat Lampung.
Lithospheric Structures beneath the Tibetan Plateau Constrained by Sn Propagation Efficiency

The uppermost mantle is a crucial region linking the lower crust and lithospheric mantle and carries important dynamic and structural information (e.g., upwelling and delamination) on interactions between the crust and mantle. An intriguing observation of an inefficient Sn wave zone beneath the Tibetan Plateau was reported but had unclear spatial distributions. By analyzing the Sn wave propagation efficiency from 34,917 Sn wave arrivals, we provide strong constraints on the lateral and depth variations in the inefficient Sn wave zone in the Tibetan Plateau. Our results show that with increasing frequencies, the inefficient Sn wave zone becomes larger, expanding to the eastern Songpan-Ganze terrane and then to the Sanjiang area and the southern margin of the Qilian orogenic belt. The northern and eastern boundaries of the inefficient Sn zone, particularly a small inefficient zone in the Qilian orogenic belt (37°N, 102°E), are clearly depicted, indicating the widespread distribution of the seismic attenuation structure or partial melt in the uppermost mantle. Moreover, we provide the depth variations in the inefficient Sn wave zone by simulating 31,538 3D raypaths with the fast marching method. We therefore constrain the depth range of the partial melt region in the uppermost mantle beneath the Tibetan Plateau. The seismic attenuation structure in the northern-central Qiangtang terrane and western Songpan-Ganze terrane extends to 130 km from the bottom of the crust, whereas that in the eastern Songpan-Ganze terrane and Sanjiang area is thinner and mainly concentrated from 90 to 130 km. Combining this information with the temporal and spatial variations in potassic-ultrapotassic magmatic rocks, it is suggested that asthenospheric materials might upwell and flow laterally beneath the Tibetan Plateau. This behavior provides a thermal driving force for the uplift of the plateau and the deformation of the crust-mantle structure.

Published: April 2022

In the development and growth of family businesses, succession is an unsolvable problem, which is also a popular focus of academic research. For a family firm, succession may be a strategic decision but also a long-term and intricate "footrace." It will have a significant impact on the long-term viability of a family firm if it is not handled appropriately. This study mainly explores the influences of family business owners' intergenerational succession intention on their family firms’ innovation strategy in China. In addition, this study further examines the moderating role of the institutional environment in the above relationship. Therefore, the data in this article comes from a survey of 271 family businesses in eight different regions of China. Also, this paper can aid the smooth transition of intergenerational transmission of small and medium-sized family businesses in addition to the untroubled development of technological innovation activities. Specifically, the institutional environment plays a negative moderating role in the relationship between family succession, radical succession, technological innovation, and a positive regulating role in the relationship between single equity succession and technological innovation.
