Published: October 2023

The increasing production of the agricultural sector in Bulukumba Regency makes the agricultural sector a dominant contribution in the formation of the economic structure, and has a significant influence on the absorption of labor. Agriculture as a labor-intensive sector in absorbing labor does not require high educational qualifications so that the population's dependence on this sector remains high. In addition to the orientation of increasing agricultural production for food security, it also provides broad access to employment opportunities. Meanwhile, the industrial sector as the leading sector is expected to continue to grow and strengthen the agricultural sector. The industrial sector in Bulukumba Regency has a significant influence on employment. Industrial growth and diversification is very important to be developed to maximize its potential and can absorb a more massive workforce in the next period.

Published: October 2023

Korosi merupakan reaksi antara logam dengan lingkungan di sekitarnya yang mengakibatkan mutu dari logam mengalami penurunan. Salah satu cara untuk menghambat terjadinya korosi pada logam adalah dengan cara membuat permukaan logam tersebut terlindungi oleh suatu inhibitor sehingga tidak terjadi kontak langsung antara logam dengan media korosif. Tujuan penelitian ini untuk mengetahui pengaruh variasi konsentrasi inhibitor terhadap laju korosi, efisiensi inhibitor ekstrak limbah kulit jagung pada baja ST 37 dan untuk mengetahui karakteristik morfologi dan unsur penyusun baja ST 37 tanpa dan dengan inhibitor dengan menggunakan SEM-EDx. Metode yang digunakan pada penelitian ini adalah metode kehilangan massa (Mass Loss). Medium korosif yang digunakan adalah NaCl 3%, dengan suhu medium sebesar 40̊C, waktu ekspos spesimen dilakukan selama 240 jam dengan dengan empat variasi konsentrasi inhibitor yaitu 0 ppm, 400 ppm, 500 ppm dan 600 ppm. Hasil penelitian menunjukkan laju korosi terbesar pada konsentrasi 0 ppm (tanpa inhibitor) yaitu sebesar 88,08 mpy, sementara laju korosi terendah yaitu pada konsentrasi 600 ppm yaitu sebesar 0 mpy. Efisiensi inhibitor korosi yang paling besar terjadi pada konsentrasi 600 ppm sebesar 100%. Karakterisasi Scanning Electron Microscopy (SEM) memperlihatkan agglomeration (gumpulan) tidak merata dengan ukuran kecil, lubang (hole) dan retakan (crack) juga lebih sedikit pada spesimen dengan inhibitor 500 ppm. Hal ini menunjukkan bahwa spesimen telah mengalami korosi dengan jenis retak tegang. Hasil Uji EDX menunjukkan adanya kandungan unsur oksigen yang cukup tinggi dan unsur Fe yang paling rendah pada specimen (a) sebesar 31,03% dan 46,48%, hal ini menunjukan bahwa Fe banyak yang teroksidasi oleh unsur O, sehingga memiliki laju korosi paling tinggi.

Abstract

OBJECTIVE
The objective of this study was to develop a robust machine-learning approach for efficient detection and grading of sesamoiditis in horses using radiographs, specifically in data-limited conditions.

SAMPLE
A dataset of 255 dorsolateral-palmaromedial oblique (DLPMO) and dorsomedial-palmarolateral oblique (DMPLO) equine radiographs were retrospectively acquired from Hagyard Equine Medical Institute. These images were anonymized and classified into 3 categories of sesamoiditis severity (normal, mild, and moderate).

METHODS
This study was conducted from February 1, 2023, to August 31, 2023. Two RetinaNet models were used in a cascaded manner, with a self-attention module incorporated into the second RetinaNet's classification subnetwork. The first RetinaNet localized the sesamoid bone in the radiographs, while the second RetinaNet graded the severity of sesamoiditis based on the localized region. Model performance was evaluated using the confusion matrix and average precision (AP).

RESULTS
The proposed model demonstrated a promising classification performance with 92.7% accuracy, surpassing the base RetinaNet model. It achieved a mean average precision (mAP) of 81.8%, indicating superior object detection ability. Notably, performance metrics for each severity category showed significant improvement.

CLINICAL RELEVANCE
The proposed deep learning-based method can accurately localize the position of sesamoid bones and grade the severity of sesamoiditis on equine radiographs, providing corresponding confidence scores. This approach has the potential to be deployed in a clinical environment, improving the diagnostic interpretation of metacarpophalangeal (fetlock) joint radiographs in horses. Furthermore, by expanding the training dataset, the model may learn to assist in the diagnosis of pathologies in other skeletal regions of the horse.

Abstract
The noise pollution has a negative effect on the human body and in some situations, exposure to high levels of pollution can lead to serious health problems. Referring to current studies, we can see a high interest in finding solutions to reduce the effects of noise pollution, such as sound absorbing panels. The purpose of this paper is to present the current stage of development of sound absorbing panels and the absorption coefficient of the materials used. The article will provide information on different types of panels and materials used in their construction, as well as their mechanical properties. New discoveries in the field related to recyclable materials used in the construction of sound absorbing panels represent an additional point of interest, as the construction of such prototypes protects the environment. The use of waste in the construction process of sound absorbing panels can be considered sustainable a future method.
Design and Development of Cooling Systems for PV Cells Performance Improvement

Published: October 2023

Abstract
This paper presents a concise review of cooling techniques for the solar PV systems.
The photovoltaic effect was firstly experimentally demonstrated by the French physicist Edmond Becquel in 1839. The first useful solar cell (6% energy efficiency) was performed by the Bell Laboratories (1950). They realized that the semiconducting materials such silicon were more efficient than selenium.
The following conditions have a significant impact on solar panel’s efficiency, in real-world use: irradiance (W/m2), shading, orientation and temperature. The ambient temperature, wind speed, time of day and the amount of solar irradiance (W/m2) make real variation in cells temperature that often rises above 25ºC. The optimum internal cell temperature is typically 25-30ºC above the ambient air temperature and solar cell performance decreases with increasing temperature with 8-15% in total power output. That’s why engineers design cooling systems to improve the efficiency of solar panels that operate in non-optimal conditions.

European Response to the Mass Influx of People Caused by the Russian Invasion of Ukraine: Testing the Limits of International Refugee Law
Authors: Honusková Věra 
Published: October 2023

SummaryRussia’s invasion of Ukraine has forced millions of people to flee the erupting armed conflict. Some of them were displaced within Ukrainian territory, others crossed the border and sought refuge in neighbouring countries and others further abroad. This article explores the limits of international refugee law in addressing this situation, which are of two kinds. First, people fleeing armed conflict are not considered refugees under the Refugee Convention if they are ‘merely’ fleeing armed conflict. Furthermore, the large number of persons arriving is also a limit. These limitations of international refugee law are filled by regional protection statuses (including temporary protection in European Union law) and the procedural ways in which protection can be granted. This article focuses on whether the current legislation in EU law is a sufficient response to the situation created by the Russian invasion of Ukraine.
The Interplay between Neutrality, Qualified Neutrality and Co-belligerency in the Context of U.S. Intervention in the Russia-Ukraine War
Authors: Ramya Kritika 
Published: October 2023

Summary
The United States of America (U.S.), and the European Union (EU) have supplied weapons to Ukraine in the ongoing Russian-Ukraine armed conflict. The Pentagon has pledged thousands of weapons to Ukraine as part of the security/military aid to worn-torn Ukraine. The supply of such weapons by a neutral/non- belligerent state stands in clear violation of the laws of Neutrality which casts a duty on the neutral states to refrain from participating in the hostilities and be impartial in their conduct towards the belligerents. However, the argument of the U.S. government in previous such instances has been that laws of neutrality have been overshadowed by the United Nations (UN) Charter and modern forms of warfare and the U.S. maintains that they fall under qualified neutrality after the 20th century. However, Qualified Neutrality is not recognised either under treaty conventions or customary international law. Similarly, international laws in terms of co-belligerency are also governed by International Humanitarian Laws (IHL) under the Four Geneva Convention of 1949 which lays down rules where military assistance by a neutral state can result in co-belligerency. However, no existing treaty or international law lays down a clear threshold for crossing from a neutral state to a co-belligerent state which has also led to an ambiguity in terms of checks and balances of the lethal weapons supplied to Ukraine by the U.S. currently. This article attempts to define the threshold in terms of severity, effectiveness, and inertia of the intervention. It further argues that the U.S. has crossed its threshold and therefore the existing laws governing violation of neutrality and affixing of state responsibility are now applicable to the U.S.

Published: October 2023

Abstract
As renewable energy demand grows, different sectors (especially energy and household) face increasing fuel shortages. Increasing interest in alternative biomass for heat production also increases the need to develop appropriate combustion technologies. This paper investigates studies carried out in the context of renewable energy. The main objectives of the article are to identify the trends between alternative biomass types and combustion processes and to find binding keywords between the topics mentioned. Two bibliometric methods – performance analysis and science mapping analysis – are applied to analyse scientific literature related to the specific application from the Scopus database. Performance analysis results show that the number of publications and citations on using alternative biomass in energy is increasing annually. The most significant number of publications in terms of biomass types are municipal solid waste and algae, while in terms of combustion technologies, it is about direct combustion and gasification. According to the results of scientific mapping analysis, algae has a strong link to climate change and sustainability issues.
Perspective: Postoperative spinal epidural hematomas (pSEH) should be treated, not ignored
Authors: Epstein Nancy E. , Agulnick Marc A 
Published: October 2023

Background:
Patients with postoperative spinal epidural hematomas (pSEH) typically require emergency treatment to avoid paralysis; these hematomas should not be ignored. pSEH patients need to undergo immediate MR studies to document the location/extent of their hematomas, and emergent surgical decompression with/ without fusion if warranted.

Methods:
The frequencies of symptomatic pSEH ranged in various series from 0.1%-4.46%. Major predisposing factors included; perioperative/postoperative coagulation abnormalities/disorders, multilevel spine surgeries, previous spine surgery, and intraoperative cerebrospinal fluid (CSF) leaks. For surgery at all spinal levels, one study observed pSEH developed within an average of 2.7 postoperative hours. Another series found 100% of cervical/thoracic, and 50% of lumbar pSEH were symptomatic within 24 postoperative hrs., while a third series noted a 24-48 postoperative window for pSEH to develop.

Results:
Early recognition of postoperative symptoms/signs of pSEH, warrant immediate MR examinations to diagnose the local/extent of hemorrhages. Subsequent emergent spinal decompressions/fusions are critical to limit/avert permanent postoperative neurological deficits. Additionally, patients undergoing open or minimally invasive spinal procedures where pSEH are suspected, warrant immediate postoperative MR studies.

Conclusion:
Patients undergoing spinal surgery at any level typically become symptomatic from pSEH within 2.7 to 24 postoperative hours. Early recognition of new neurological deficits, immediate MR studies, and emergent surgery (i.e., if indicated) should limit/minimize postoperative neurological sequelae. Thus, pSEH should be treated, not ignored.

Published: October 2023

Целью работы являлось проектирование рецептуры и технологии хлебобулочных изделий с применением апипродуктов (цветочной пыльцы-обножки). В работе использовались стандартные и общепринятые методики. Пыльца-обножка является уникальным источником биологически активных веществ, в ее состав входят белковые вещества, незаменимые аминокислоты, ферменты, фитогормоны, пищевые волокна, в значительных количествах содержатся флавоноидные соединения, витамины В1, В2, Е, РР, β-каротин. Из минеральных элементов высоко содержание магния, фосфора, железа, цинка, селена, меди. Для обоснования применения пыльцы-обножки в технологии хлебобулочных изделий исследован ход технологического процесса, органолептические и физико-химические показатели качества хлеба. Установлено, что добавление пыльцы-обножки приводит к форсированию процесса созревания теста за счет наличия в составе пыльцы-обножки значимого количества сахаров, витаминов и минеральных элементов, что вызывает необходимость сокращения продолжительности брожения теста на 30‒40 минут и расстойки тестовых заготовок на 5–15 минут. Доказано положительное влияние пыльцы-обножки на физико-химические показатели и цвет корки, состояние мякиша, вкус и запах изделий. Употребление хлеба с добавлением 8 % пыльцы-обножки, приготовленного по разработанной рецептуре и технологии, покрывает 18 % нормы суточной потребности в пищевых волокнах, более 20 % от суточной потребности витамина В1, более 50 % от суточной потребности витамина Е, более 40 % от суточной потребности β-каротина и флавоноидных соединений.
The value of manual backward contact tracing to control COVID-19 in practice, the Netherlands, February to March 2021: a pilot study

Published: October 2023

Background
Contact tracing has been a key component of COVID-19 outbreak control. Backward contact tracing (BCT) aims to trace the source that infected the index case and, thereafter, the cases infected by the source. Modelling studies have suggested BCT will substantially reduce SARS-CoV-2 transmission in addition to forward contact tracing.

Aim
To assess the feasibility and impact of adding BCT in practice.

Methods
We identified COVID-19 cases who were already registered in the electronic database between 19 February and 10 March 2021 for routine contact tracing at the Public Health Service (PHS) of Rotterdam-Rijnmond, the Netherlands (pop. 1.3 million). We investigated if, through a structured questionnaire by dedicated contact tracers, we could trace additional sources and cases infected by these sources. Potential sources identified by the index were approached to trace the source’s contacts. We evaluated the number of source contacts that could be additionally quarantined.

Results
Of 7,448 COVID-19 cases interviewed in the study period, 47% (n = 3,497) indicated a source that was already registered as a case in the PHS electronic database. A potential, not yet registered source was traced in 13% (n = 979). Backward contact tracing was possible in 62 of 979 cases, from whom an additional 133 potential sources were traced, and four were eligible for tracing of source contacts. Two additional contacts traced had to stay in quarantine for 1 day. No new COVID-19 cases were confirmed.

Conclusions
The addition of manual BCT to control the COVID-19 pandemic did not provide added value in our study setting.
