<p>The main problem faced by the broiler industry from time to time was its vulnerability to various large and short-term shocks. This study aimed to assess and formulate policy recommendations for the development of the supply chain integration of chicken meat. The analytical methods used in this study were the supply chain, market integration, and price fluctuation analysis. The results of this study indicated that supply chain actors in live broiler commodities and chicken meat were still quite long and less competitive. The dominant position in determining prices in the chicken meat supply chain was integrator companies and collectors. Broiler market integration at the farm level in the production center in West Java and the retailer level in the City of Bandung was not well integrated with the Market Index Connection (IMC) value of 5.956 (not integrated) and in East Java was also not integrated but with better the IMC value of 1.654. The level of chicken meat price fluctuations was quite moderate, as indicated by the Coefficient of Variation (CV) value 6.82. Broiler prices at the producer level were more volatile than the price of chicken meat at the consumer level. Policy implications drawn from this study are the need to cut the very long supply chain, improve the market structure towards a more competitive one, increase market integration, and maintain stabilization of chicken meat prices.</p><p> </p><p>Abstrak</p><p>Permasalahan pokok yang dihadapi industri broiler dari waktu ke waktu adalah kerawanannya terhadap terhadap berbagai goncangan besar dan berjangka pendek. Penelitian ini bertujuan untuk mengkaji dan menghasilkan rekomendasi kebijakan pengembangan rantai pasok daging ayam ras secara terpadu.Metode analisis yang digunakan adalah analisis rantai pasok, integrasi pasar, dan fluktuasi harga. Hasil penelitian ini menunjukkan pelaku rantai pasok pada komoditas broiler hidup dan daging ayam masih cukup panjang dan kurang kompetitif. Posisi dominan dalam penentuan harga pada rantai pasok daging ayam adalah perusahaan integrator dan pedagang pengepul. Integrasi pasar broiler di tingkat peternak di daerah sentra produksi di Jawa Barat dan di tingkat pedagang pengecer di Kota Bandung tidak terintegrasi dengan baik dengan nilai <em>Index Market Conection</em> (IMC) sebesar 5,956 (tidak terintegrasi), dan di Jawa Timur juga tidak integrasi namun dengan nilai IMC yang menunjukkan lebih baik, yaitu 1,654. Tingkat fluktuasi harga daging ayam cukup moderat, yang diindikasikan oleh nilai <em>Coefisien Variasi</em> (CV) 6,82. Harga broiler di tingkat produsen lebih fluktuatif dibandingkan harga daging ayam ras di tingkat konsumen. Implikasi kebijakan dari temuan penelitian ini adalah perlunya memotong rantai pasok yang terlalu panjang, memperbaiki struktur pasar ke arah struktur yang lebih kompetitif, meningkatkan keterpaduan pasar dan menjaga stabilisasi harga daging ayam.</p>

<p>Natural resource management generally involves parties who have conflicts of power and interests. For Indonesia, palm oil development has a positive impact on people's welfare and economic gain. However, the palm oil industry's growth in its development caused controversy, especially among the international community. In this study, a stakeholder analysis was carried out to determine the degree of influence and interest of the relevant engagements and formulate an appropriate and solutive communication strategy in improving palm oil governance in Indonesia. The stakeholder analysis study was carried out based on the results of three levels of Fairclough discourse analysis based on online media publications, interviews, and observations during 2015-2018. The findings of this study indicate that there are 31 of the 40 stakeholders identified in the Crowd quadrant that showed an uproar about the controversy over oil palm development in Indonesia came from parties who did not need to be significant for governance improvement. On the other hand, stakeholders who have strategic positions are not invited to determine more actively to reach consensus. This study implies that sustainable oil palm development can be achieved if accompanied by promoting constructive communication among stakeholders to reach mutual understanding.</p><p> </p><p>Abstrak</p><p>Pengelolaan sumber daya alam umumnya melibatkan pihak-pihak yang memiliki konflik pengaruh dan kepentingan.

<p>Efforts to improve the competency of agricultural extension workers have been carried out through education and training by the Agency for Agricultural Extension and Human Resources Development. Improving the competence of agriculture extension workers through the utilization of communication media has not been used intensively by the government. The purpose of this study is to know the level of influence of communication media utilization on the competence of agricultural extension workers. The study was used a quantitative approach through an online survey of 203 agricultural extension workers at the Assessment Institute for Agricultural Technology from 33 provinces. The results showed that the utilization of communication media and characteristics of individual had a significant effect on the competence of agricultural extension workers. Environmental support factors have a significant effect on the utilization of communication media and have an indirect effect on the competence of agricultural extension workers. The most and significant influence on the competence of agricultural extension comes from the utilization of communication media which is 4.38. Meanwhile, the significant factor affecting the utilization of communication media is only in the form of environmental support of 0.34. Therefore, to improve the competence of agricultural extension workers, utilization of communication media in the dissemination of agricultural information should be increased. Furthermore, to increase the utilization of communication media in the dissemination of agricultural information, the environmental support of extension activities, such as literacy training on the use of variation communication media, should be improved.</p>
PALEOENVIRONMENTAL ANALYSIS OF A LOWER CRETACEOUS PALEOLAKE FROM THE IGUATU BASIN BASED ON ITS OSTRACOD FAUNA AND XRF DATA

Published: December 2021

ABSTRACTThis paper presents the results of a paleoenvironmental study of two Hauterivian–Aptian adjacent sections (Transnordestina A/B) of the Iguatu Basin using ostracods and aided by X-ray fluorescence (XRF), total organic carbon (TOC), total sulfur (S), and spectral analyses. Cluster analysis divided the 10 genera found into two main groups: one composed of Alicenula-Pattersoncypris?-Brasacypris-Hastacypris-Ilyocypris?, and the second composed of Cypridea-Looneyellopsis-Rhinocypris?. The first group is interpreted as representing paleoenvironments with permanent waterbodies, such as lakes, and the second as being indicative of ephemeral settings, such as temporary pools in an inundation plain. XRF analysis using the positive peaks of Ca/Ti and Ca/ΣTi, Fe, Al ratios show a few dry periods, particularly in the lower and middle part of Transnordestina A, between 0 to 175 m and 385 to 475 m, which also display a small number of ostracods. Total S shows several high peaks which might be indicative of gypsum deposition during droughts. Spectral analysis of molar Ti/Al ratio shows two intervals with different sedimentation rates, between 0 and 233 m, and 233 to 836 m. For the first interval, six 100 ka eccentricity cycles were identified; the low number of ostracods for the interval and highly variable Ca/Ti and Ca/ΣTi, Fe, Al values indicate a different sedimentation rate in a drier environment. For the second interval, ten 405 ka cycles were identified; its higher ostracod count and more stable Ca/Ti and Ca/ΣTi, Fe, Al values could be indicative of increasing humidity.

Abstract
IntroductionWater should comply with standard/regulatory physio-chemical and biological parameters to ensure that it is safe for domestic use. We therefore sought to assess the physico-chemical and biological quality of groundwater sources in Kadama subcounty, Kibuku district, Eastern Uganda. MethodsA cross-sectional quantitative study was conducted. We collected water samples from twenty-three functional water sources. We assessed the turbidity, pH and presence of Escherichia coli (E. coli) using the turbidity meter, pH meter and membrane filtration technique, respectively. Furthermore, physical sanitary inspection of the water sources was done using a standard pretested observational checklist to assess existing risk factors.ResultsThe majority, 69.5% of the water sources included in the study were boreholes, with about 43.5% of them from Nandere parish. Majority of the water sources 86.9% (20/23) had clogged/blocked drainage channels, about a third of water sources 60.9% (14/23) did not have fences/protection around them and majority of the water sources, 82.6% (19/23) had stagnated apron. Some water sources 8.7% (2/23) had open defecation around them. The water samples had a mean pH of 6.87 (SD 0.920) with 4.4% acidic, 86.9% normal/acceptable pH level and 8.6% in alkaline state. About two-thirds (65.3%) of these water sources had turbidity levels less than 5 NTUs. In addition, boreholes had a better turbidity score of 81.2% (13/16) compared to the water wells 71.4% (5/7). About half, 43.5% of the water sources were above the WHO recommended range of zero coliforms. ConclusionsSome ground water sources had sanitary risk factors and significant levels of E. coli which makes them unfit for human consumption, though they can be used for other domestic purposes including washing clothes. This calls for urgent need to keep surrounding water sources clean and continuously disinfect drinking water from groundwater sources before human consumption.
WITHDRAWN: MH370 Controlled Eastward Veering and Descent After the 6th Arc
Authors: Lyne Vincent 
Published: December 2021

Abstract
Past expert analyses of communication signals from missing Malaysian Airlines MH370 reconciled Burst Frequency Offset (BFO) errors up to the 6th of 7 arcs for a southerly track. After the 6th arc, the Satellite Data Unit (SDU) power-up or reboot resulted in settling errors in the last two data points that were ignored (first search) and later bounded (second search). For the second search, investigators invoked a high-speed vertical descent to account for BFO errors for the south track fuel-starved scenario. Two searches disappointingly failed to find the implied violent-crash site. We report that interpretations were flawed in suggesting the plane dived vertically, as investigators did not recognize that BFO extrapolations implicitly implied mathematically that the plane was also cruising along the south track, but with no fuel. Our reanalysis used the “Penang Longitude” (PL) theory that predicted a similar southerly track to the 6th arc, and that MH370 subsequently veered eastwards and descended. Doppler Shifts from vertical motions were replaced with plausible horizontal veering and declination of a high-speed aircraft. Veering predicted by the PL theory plus controlled descent plausibly accounts for nominal 7th arc BFO discrepancies for the warm-reboot scenario. We conclude that the fuel-starvation scenario analyses wrongly implied a vertical high-speed crash that ignored the impossible implicit southerly cruise, with no fuel, assumption. Instead, MH370 was piloted to a precise glide landing under power, east of the 7th arc.

Nitinol is widely used in the production of medical devices, especially the ones that are designed for minimally invasive treatment, such as stents to restore vascular patency, stent grafts to eliminate aneurysms, and cava filters to trap blood clots. One of the most important characteristics that determines the reliability of the functioning of such products in the human body is the state of the surface layer. The higher the surface quality, the less negative impact is on the circulatory system, the walls of blood vessels and the higher the biological compatibility of the product. Electrochemical polishing methods are mainly used to improve the surface quality of nitinol products. The disadvantage of the applied electrochemical methods is the need to use aggressive electrolytes that contain toxic components, such as hydrofluoric acid, sulfuric acid, perchloric acid, nitric acid, methanol. As an alternative to the existing methods of electrochemical polishing, we have developed electrolytic-plasma polishing (EPP), a new highly efficient process for improving the surface quality of nitinol products. The most important advantage of the method over traditional electrochemical polishing is the use of aqueous salt solutions with a concentration of 4 % as electrolytes. Based on the results of the studies performed, the most rational EPP mode was established, the use of which during polishing of nitinol provides surface cleaning from scale, polishing with a decrease in the roughness parameter Ra by 0.344 µm and an increase in pitting potential by 33 %.
Correlation approach in predictor selection for groundwater level forecasting in areas threatened by water deficits

Published: December 2021

Abstract
Reliable long-term groundwater level (GWL) prediction is essential to assess the availability of resources and the risk to drinking water supply in changing climatic and socio-economic conditions, especially in areas with water deficits. The modern approach in this area involves the use of machine learning methods. However, the greatest challenge in these methods lies in the optimization of input selection. The presented research concerns the selection of the best combination of predictors using the Hellwig method. It served as a preprocessing technique before GWL prediction using support vector regression (SVR) and multilayer perceptron (MLP) for three wells in the Greater Poland Province, where the largest water deficits occur, in the period 1975–2014. The results of this method were compared with those of the regression method, general regression model. For the case study under investigation, the Hellwig method provided the best set of predictors consisted of GWL at lags of −1 and −2 months, precipitation from the current month, and delayed from −1 to −6 months, and past temperature at −1, −3, −4 and −6 months. Such input led to a model accuracy of 0.003–0.022 for a mean squared error and r2 of &gt;0.8. The results obtained with SVR were slightly better than those with MLP. Moreover, every well required an individual set of predictors, and additional meteorological inputs improved the models’ performance.
Water-tourism nexus: impact of the water footprint of inbound tourists to China
Authors: Zhang Yu , Tian Qing 
Published: December 2021

Abstract
The water footprint is a new concept used to understand the water resources uses; however, few studies have applied it to the service industry and the impact analysis are not abundant. This study explored how water footprint of tourism influenced water resources based on inbound tourists to China from 2001 to 2018. The total water footprint of inbound tourists (ITWF) was 7273.15*106 m3, and showed an upward trend. The spatial pattern was agglomerated, being mainly concentrated in North China, East China, and South China. The standard deviation ellipse showed that the horizontal axis was first east, and then west. According to the background water footprint, the ‘contribution’ of ITWF to the background water surplus differed in each province. According to the background water stress, the impact roughly separated into large, medium, and small using overlay analysis. Based on ITWF and water stress levels, the 31 administrative regions of mainland China were separated into four types and put forward suggestions: double-high pressure type, cautious development type, double-low potential type and optimised development type. This study provided a theoretical reference for governments, and is conducive to promoting the coordinated and sustainable development of tourism and water resources.
Evaluation of advanced oxidation processes for β-blockers degradation: a review
Authors: Kovács Krisztina , Tóth Tünde , Wojnárovits László 
Published: December 2021

Abstract
This study summarizes the results of scientific investigations on the removal of the three most often used β-blockers (atenolol, metoprolol and propranolol) by various advanced oxidation processes (AOP). The free radical chemistry, rate constants, degradation mechanism and elimination effectiveness of these compounds are discussed together with the technical details of experiments. In most AOP the degradation is predominantly initiated by hydroxyl radicals. In sulfate radical anion-based oxidation processes (SROP) both hydroxyl radicals and sulfate radical anions greatly contribute to the degradation. The rate constants of reactions with these two radicals are in the 109–1010 M−1 s−1 range. The degradation products reflect ipso attack, hydroxylation on the aromatic ring and/or the amino moiety and cleavage of the side chain. Among AOP, photocatalysis and SROP are the most effective for degradation of the three β-blockers. The operating parameters have to be optimized to the most suitable effectiveness.

Published: December 2021

Essa pesquisa objetiva analisar a influência do curso de medicina na espiritualidade do estudante, buscando conhecer a espiritualidade do estudante de medicina e a sua concepção sobre este tema, e comparar a percepção do estudante de medicina sobre a importância da espiritualidade no campo da saúde, antes e depois de cursar a disciplina que aborda esta temática. Estudo qualitativo baseado em narrativas orais, gravadas e, posteriormente, transcritas, seguindo o modelo de análise de dados qualitativos proposto por Graham Gibbs. Foi aplicado com os informantes um questionário sóciodemográfico e, em seguida, realizada uma entrevista estruturada. A amostra constou de estudantes de medicina, maiores de 18 anos, que estavam cursando o segundo, terceiro, quarto, sexto, sétimo ou oitavo semestre em uma universidade pública de Salvador, Ba. Os resultados mostram que o curso de medicina influenciou a maior parte dos estudantes entrevistados, e essa influência não demonstrou ser dada em função da crença, religião ou semestre em curso, mas sim de modo subjetivo de acordo a percepção pessoal que cada entrevistado possui a respeito da sua espiritualidade e das suas vivências no decorrer do curso. A grande maioria foi influenciada a favor da sua espiritualidade, acentuando e criando novas convicções, enquanto uma pequena parte relatou uma influência contrária à sua espiritualidade do curso, fazendo-os reconsiderar compreensões e posicionamentos anteriormente tidos. Ademais, mais da metade da amostra relatou já ter vivenciado um fato marcante na sua espiritualidade, diretamente relacionado ao curso de medicina.

Authors: Macedo Otavio , Silveira Joaquim Carlos Fest da , Rangel Luiz Felipe Gilson de Oliveira , Silva Catia Maria Santos Diogo 
Published: December 2021

A utilização de uma substância irrigadora no processo do tratamento endodôntico é de extrema importância, afinal, para que ocorra a eficácia do tratamento é necessária a eliminação de qualquer produto, bactéria ou toxina existente no interior dos canais, sendo feita de maneira mais profunda. Portanto, para que uma solução irrigadora seja identificada como ideal, ela deve também, conter outras propriedades necessárias, como o poder de dissolução tecidual, atividade lubrificante, viscosidade, baixa tensão superficial, eliminação de lipopolissacarídeos e biocompatibilidade com os tecidos perirradiculares. Diante disso, o hipoclorito de sódio vem sendo a solução irrigadora mais utilizada e indicada, por conta da sua forte ação antimicrobiana e sua dissolução de tecido orgânico. Assim, o principal objetivo deste trabalho é discutir sobre a ação do hipoclorito de sódio como solução irrigadora no tratamento endodôntico, levando em conta sua importância nesse processo e suas propriedades. O trabalho é de cunho bibliográfico, e foi construído através da busca em obras como artigos científicos, revistas on-line, periódicos e trabalhos acadêmicos.
