Authors: Ranga Rao A
Published: December 2023

This work aims, optimization of simultaneous biosorption of Cr(III) and Cr(VI) onto Gelidilla acerosa, a marine macro algae using multiple response optimization combined with central composite design of design of experiments. The three important physicochemical parameters of biosorption such as initial pH, initial concentration of metal solution and biosorbent dosage were optimized. The most favorable condition for simultaneous removal of Cr(III) and Cr(VI) were: pH 2.8, initial concentration 20 mg l-1 and biosorbent dosage 0.05g with maximum overall desirability of 1.0. Surface morphological features of biosorbent were studied using FTIR. The nature of biosorption was analyzed by fitting the equilibrium data to various adsorption isotherms and found that both Langmuir and Freundlich model were best fitted with R2: 0.99 for both chromium species. The maximum biosorption capacities predicted from Langmuir model were 285.71 mg g-1 for Cr(III) and 270.27 mg g-1 for Cr(VI). The pseudo-second order kinetic model was found to be proper approach to demonstrate biosorption kinetics indicating chemisorption with film diffusion as the rate controlling mechanism. The results demonstrated that multiple response optimization combined with central composite design using desirability function was best approach for optimization of simultaneous biosorption of Cr(III) and Cr(VI) from aqueous medium.

Authors: Kuo Wei-Puo
Published: December 2023

This paper reports the first use of a charcoal processing system with an internal combustion furnace (CPSICF) to produce pyroligneous acid from rice husk, called rice husk vinegar. The gate width in CPSICF influenced air intake, which directly affected the temperature of the furnace that played a key role during pyrolysis. The process characteristics of rice husk vinegar collected from (A) the internal combustion furnace cover and (B) chimney are discussed separately. The total rice husk vinegar weight was 13.13-14.08 kg with cooling water but only 7.23 kg without cooling water. The pH value and acidity ranges were 3.1-3.6 and 5.9%-8.3%, respectively. The tar content was 1.3-3.9 but was 6.1 in the vinegar obtained from the chimney without cooling water. The suspended solid content was 2.1-8.5 mg/L but was 20.6 in the vinegar obtained from the chimney without cooling water. These results are similar to those for other charcoal processing systems.

Authors: Halala Harko
Published: December 2023

In the agriculture sector beef cattle sub-sector plays a great role by employing many task forces in agrarian countries and serve as source of income and food. Ethiopia’s predominant source of animal feed is natural pastures, forages and browse of varying nutritive value. These feeds are generally communal or are communally administered. “Value added” means adding value to a raw product by taking it to at least the next stage of production. Beef cattle production, marketing and value addition issues are yet not well addressed through scientific approach in the study area. To address these problems this study was conducted in Maraka and Essara districts in Dawuro Zone, Southern Ethiopia with general objective of analyzing factors determine beef cattle production and value addition in the study area. The random sampling procedure is used to select sample respondents such as 130 beef cattle producers from 9 rural kebeles, 16 beef cattle traders and beef retailers. Primary data are collected from sample respondents through questionnaires and checklists and secondary data are also used. Financial position indicators like value share and value-added calculations are included. Statistically significant variables in probit model analysis for factors determine the accesses to veterinary service (drug) are years of experience in beef cattle production, age of household head, family size, land size, and other livestock at household head. In the case of access to feed and feed sources statistically significant variables are sex of the household heads, land size, market information and income from other sources. Percent of value added by beef cattle producers, traders and beef retailers on different sized beef cattle is well computed. Conclusions drawn are Encouraging savings of income obtained from other sources, improving access to veterinary services, providing trainings on improved beef cattle production, organized market linkage and value addition activities.

Critique of USGA Reco mmendations for A Method of Putting Green Construction
Authors: J Brown Philip
Published: December 2023

The United States Golf Association (USGA) originally published specifications for greens construction in a 1960 five-page publication. The document was designed as a guide to golf course builders to ensure greens would provide good playing conditions for many years, and is based on research from the Green Section, UCLA, and Texas A & M College. Reco mmendations from this document were designed to provide a green with sufficient drainage and resistance to compaction, a combination difficult to achieve without a degree of compromise. Since this release, the original reco mmendations have been updated four times, most recently in 2018. The document gives guidance on a range of soil physical properties including bulk density, porosity, saturated hydraulic conductivity, grain size distribution, bridging factors, and amendments. The most recent version of the specifications builds on previous versions; however, some reco mmendations warrant further examination such as the statement that addition of small amounts of soil to a rootzone mix will likely reduce the infiltration rate without a significant increase in water retention.

Published: December 2023

Information and communication technologies (ICT) allow increase of work efficiency of accounting data processing and business management. Traditional understanding of work efficiency most cases deals only with productivity of consultants, who are providing accounting data input, processing and preparation of reports for farmers. Less attention has be paid to changes of functional abilities of software, technical and communication equipment as well as behaviour of staff, providing consulting service. This article include results of theoretical analysis of factors, influencing understanding of consultants work efficiency in face with higher needs and expectations of consumers. For empirical investigation there were used the data received during questioning of consultants working at the Lithuanian Agricultural Advisory Service who are providing processing of farmers’ farms’ accounting data, preparing various reports for tax office and other official institutions, providing analysis of financial situation of the farms and taking recommendations on improvement of farms management. As the results of made research shown changes that have occurred at the Lithuanian Agricultural Advisory Service over the last two decades due to modernisation of data processing software and modern ICT use.
Physiological traits involved in grazing tolerance of alfalfa genotypes
Authors: de Ávila  Mariana Rockenbach
Published: December 2023

Alfalfa [1] is one of the most largely distributed forage legume species in the world and it is used on more hectares than any other forage legume. Even so, alfalfa production in Brazil is still limited by the low persistence of this species, especially when used for grazing. Therefore, the objective of this study was to evaluate and select grazing-tolerant germplasm by evaluating genotypes based on their physiological traits. Eight alfalfa genotypes were grown in two different and simultaneous experiments. The experiment ‘A’ evaluated physiological traits: a) chlorophyll content b) sum of lateral roots and shoot and c) length of the first internode The experiment ‘B’ consisted of a jasmonate treatment, which induced remarkable effects on alfalfa roots performance. The CRAltR genotype showed the most promising results for length of the first internode 0.429 cm at the last day of evaluation (day 15). Furthermore, this genotype obtained higher rates in the evaluation of chlorophyll. E1C4AltR in addition to being selected in previous studies for grazing tolerance showed variability for decumbent habit and intermediate values for chlorophyll. The genotypes E1C4 AltR and CRAltR presented more promising results and they will be used for further field evaluations in Brazil.
Classify Rice Disease Using Self-Optimizing Models and Edge Computing with Agricultural Implications
Authors: Mingle Damian
Published: December 2023

Rice continues to be a primary food for the world’s population. Over its complex history, dating as far back as 8,000 B.C., there have been agricultural challenges, such as a variety of diseases. A consequence of disease in rice plants may lead to no harvest of grain; therefore, detecting disease early and providing expert remedies in a low-cost solution is highly desirable. In this article, we study a pragmatic approach for rice growers to leverage artificial intelligence solutions that reduce cost, increase speed, improve ease of use, and increase model performance over other solutions, thereby directly impacting field operations. Our method significantly improves upon prior methods by combining automated feature extraction for image data, exploring thousands of traditional machine learning configurations, defining a search space for hyper-parameters, deploying a model using edge computing field usability, and suggesting remedies for rice growers. These results prove the validity of the proposed approach for rice disease detection and treatments.
When Plant Breeding Meets Population Genomics
Authors: Bergero Roberta
Published: December 2023

Production of cherries with large fruit size, rich color and high firmness is extremely critical in today’s competitive market. The influence of Foliar TRIGGRR® (TRIGGRR®), a cytokinin-containing compound, on fruit quality attributes of ‘Bing’, ‘Chelan’, and ‘Lapin’ were studied under climate conditions of Intermountain West region in Southwest Idaho, USA. TRIGGRR® reduced fruit-stem removal force, fruit firmness, and soluble solids in ‘Bing’ cherry. However, application of TRIGGRR® significantly improved fruit color but did not have any effect on fruit weight, firmness, or soluble solids concentration in ‘Chelan’ cultivar. TRIGGRR® significantly improved fruit quality of ‘Lapin’ cherry by enhancing fruit size, fruit-stem removal force, and firmness. Thus, the application of this compound on ‘Chelan’ and ‘Lapin’ cultivars is recommended, as fruit from this region is mostly exported to far destinations, and fruit with higher rigidity and firmness can withstand damages and bruising during the transportation. Studying potential synergism or antagonism effect of TRIGGRR® with other growth regulators in cherries is strongly recommended.

Covid-19 Responses for Equity (CORE) was a three-year, CA$25m rapid research initiative that brought together 20 research projects to understand the socioeconomic impacts of the pandemic, improve existing responses, and generate better policy options for recovery. The research, funded by the Canadian International Development Research Centre (IDRC), took place across 42 countries in Africa, Asia, Latin America and the Middle East. The Institute of Development Studies (IDS) supported CORE to maximise the learning generated across the research portfolio and deepen engagement with governments, civil society, and the scientific community. This publication celebrates the impact of that research, and highlights Stories of Change from seven of the CORE projects that successfully influenced policy, practice, and understandings of the crisis. Collectively, these individual case studies provide a narrative about the nature of research impact in emergencies and the implications for the design and delivery of future rapid response research initiatives. There are clear lessons around the importance of organisational reputation, and the value of co-designing research with decision makers whilst simultaneously taking a critical position. Every story here emphasises the need to understand political context and to explore the trade-offs between research rigour and the timeliness of evidence. Above all, they illustrate the value of flexible funding arrangements that enable local teams to respond to fast-moving crises. These stories demonstrate unequivocally the value of locally led research responses to emergencies with the right international flow of resources and support. CORE’s research teams were well-placed to bring together communities, civil society organisations, and governments to create a space for vulnerable and marginalised groups to discuss their lived experiences of the pandemic and bring these perspectives into policy conversations. Their success hinged on their hyper-local knowledge and their unswerving focus on providing real-time evidence to advocate for the wellbeing of affected communities.

Published: December 2023

Penelitian ini bertujuan untuk mengetahui bagaimana kepedulian, disiplin, dan tanggung jawab birokrat melayani masyarakat pada Badan Pendapatan Daerah Provinsi Sumatera Utara. Metode Penelitian yang digunakan adalah kualitatif. Hasil penelitian ini menunjukkan bahwa perilaku birokrasi dalam melayani Badan Pendapatan Daerah Provinsi Sumatera Utara masih perlu ditingkatkan agar masyarakat benar-benar mendapatkan pelayanan yang maksimal. Hal ini terlihat dari 1) kepedulian terhadap masyarakat masih kurang karena masih adanya tindakan-tindakan diskriminatif dan masyarakat akan lebih percaya terhadap kinerja aparatur apabila terdapat transparansi dan profesionalisme dalam pendataan; 2) disiplin pegawai juga kurang karena sering ditemukan datang kerja terlambat, pulang lebih awal dan dress code kadang tidak dipatuhi; dan 3) dalam hal tanggung jawab.

Published: December 2023

Penelitian ini bertujuan untuk menganalisis pengaruh inflasi, nilai tukar rupiah dan distribusi dana zakat terhadap daya beli masyarakat di sumatera utara. Metode penelitian ini menggunakan analisis deskriptif kuantitatif dengan jenis data time series. Data sekunder yang didapatkan dari Badan Pusat Statistik, Bank Indonesia, dan Badan Amil Zakat Sumatera Utara. Teknik analisis data dengan SPSS 22 menggunakan uji regresi linear berganda. Hasil penelitian ini menunjukkan bahwa inflasi dan distribusi dana zakat berpengaruh signifikan terhadap daya beli masyarakat di Sumatera Utara. Karena, inflasi membuat nilai mata uang menjadi turun sehingga daya beli pun juga melemah. Melemahnya daya beli tersebut terjadi karena peningkatan harga yang dilakukan penjual sebagai upaya mendapatkan nilai agar tetap untung setelah terjadi inflasi. Sedangkan distribusi zakat berpengaruh karena Zakat berfungsi dalam menyediakan Jaring Pengaman Sosial (JPS) dan menjamin terpenuhinya kebutuhan dasar bagi masyarakat, mengurangi kesenjangan, mendorong berputarnya roda perekonomian, dan mendorong pemanfaatan dana yang digunakan secara produktif serta meningkatkan daya beli masyarakat. Nilai tukar rupiah tidak berpengaruh signifikan terhadap daya beli masyarakat, Karena Nilai tukar valuta asing senantiasa mengalami perubahan, sehingga salah satu dampak yang terlihat jelas dalam masyarakat adalah perubahan daya beli.

Legislación como literatura: La hisba de Ibn῾Abdūn y la mujer en la Sevilla almorávide
Authors: Bollo-Panadero María Dolores
Published: December 2023

Tras la conquista almorávide, al-Ándalus experimenta un cambio profundo en su estructura social, económica y gubernamental. Con base en las ideas y teorías propuestas por el Law and Literature Movement, este artículo analiza las regulaciones relacionadas con las mujeres en el tratado de Ibn῾Abdūn. La obra, escrita hacia finales del siglo XI o principios del XII, forma parte del género de la literatura árabe denominado ḥisba, y el objetivo de estos textos era regular las transacciones comerciales, al tiempo que servían para reforzar la sharía en los espacios públicos y privados. Destinado a ser una lista de regulaciones de los diferentes gremios y de las instituciones urbanas de Sevilla, el opúsculo de Ibn῾Abdūn termina, en varias instancias, codificando el comportamiento de la población civil, y especialmente el comportamiento de las mujeres, cuyas vidas sufrieron un cambio radical por la imposición de una nueva ideología, en los espacios públicos de la ciudad. El tratado representa así una ventana abierta en un momento crucial de la historia de al-Ándalus y un valioso instrumento para el estudio y entendimiento de la situación de la mujer en la Sevilla de comienzos del siglo XII.

Published: December 2023

O proselitismo feito por lideranças pentecostais e políticas em períodos eleitorais faz estes atores sociais se aproveitarem da homogeneidade evangélica para implementarem projetos de poder via processos democráticos. Para melhor compreender o fenômeno, este artigo analisou cultos de cinco igrejas durante o pleito da Câmara Municipal de Curitiba em 2020 com o auxílio da Semiolinguística de Charaudeau, que detectou, organizou e aferiu estratégias político-discursivas. Enquanto líderes religiosos apresentaram o ethos de chefe e um falar forte e delocutivo, usado para aconselhar eleitoralmente seus/suas fiéis em nome de Jesus Cristo, candidatos(as) basearam seus ethé e pathé em caráter, virtude e crenças partilhadas para se aproveitarem da homogeneidade do grupo, cada vez mais vinculado ao fundamentalismo. Dessa forma, pretendemos contribuir para o debate sobre a participação dessas lideranças na política partidária de um Estado laico imerso em uma transição que em breve fará do evangelismo a religião com o maior número de filiações no Brasil.

Sejak saat itu belum ada perubahan. Hasil penelitian juga menunjukkan bahwa dari total biaya penanganan sampah yang dikeluarkan selama 1 tahun atau sebesar Rp 5.477.061.600, penerimaan retribusi sampah non rumah tangga hanya mampu menutup 5% dari total penerimaan retribusi yang dibutuhkan yaitu sebesar Rp.278.394.600. Penerimaan tersebut perlu ditingkatkan untuk meningkatkan pelayanan persampahan di Kota Mojokerto. Hasil penelitian terkait potensi penerimaan retribusi di Kota Mojokerto menunjukkan bahwa kenaikan penerimaan retribusi dapat terjadi jika tarif yang sudah ada dinaikkan sampai dengan 2x lipat setiap tahunnya. Selain itu pemerintah Kota Mojokerto juga harus menetapkan klasifikasi wajib retribusi bagi rumah tangga. Hasil penelitian ini diharapkan mampu memberikan kontribusi secara teoritis yaitu memperkuat dan memperkaya literasi terkait dengan strategi optimalisasi retribusi persampahan untuk menaikkan Pendapatan Asli Daerah (PAD). Selain itu, penelitian ini diharapkan berkontribusi secara praktis terhadap kebijakan Pemerinta Kota Mojokerto sebagai bahan pertimbangan dalam perubahan peraturan terkait retribusi sampah dan kenaikan tarif.

Experimental Investigation on Countermeasures for Gravel Bed Scouring and Driftwood Deposition Around Pier
Authors: Yasuda Youichi , Ishitsuka Toshiki
Published: December 2023

During floods, driftwood is generated simultaneously with sediment runoff, may impinge and accumulate on bridge piers. In this case, the water level rises upstream of the bridge, flooding from the river, resulting in major damage, such as overtopping and collapse of houses and bridges. Further, a high velocity flow passing over the pier due to impact of the flow at the upstream face of the pier causes scouring of the river bottom around the pier. In this study, the installation of consecutively assembled boulders was proposed in order to protect against scouring around the pier. A trapezoidal elliptical shape pier was also proposed as a countermeasure to reduce driftwoods capturing. As a comparative study, revetment blocks, which are conventionally used as countermeasure works, were installed. The experimental results revealed that the proposed structure was effective in reducing driftwood deposition and preventing gravel bed scouring, based on analysis using flow velocity with time series variation, vector diagrams, and driftwood model.

Atividades de massa (ciclismo, caminhada e corrida) têm sido destacadas como importantes ferramentas para aumento dos níveis de atividade física (AF) da população. Enquanto uma atividade realizada em espaço outdoor, características do ambiente físico e natural devem ser considerados como importantes determinantes do envolvimento na prática. O objetivo do estudo foi verificar o papel desempenhado por fatores ambientais no envolvimento do treinamento em corredores de rua da região norte do Brasil. Trata-se de estudo transversal, denominado “InTrack”, realizado com praticantes de corrida de rua não profissionais. A amostra é composta por 76 (35,6±1,2 anos) praticantes de corrida de rua da região Norte do Brasil. Um questionário online foi usado para obter informações sobre idade, sexo, índice de massa corporal, treinamento. Características do ambiente (iluminação pública, existência e pavimentação de calçadas, espaços verdes nos estados), foram obtidos através do acesso aos dados oriundos da pesquisa Características urbanísticas do entorno dos domicílios. A análise estatística, realizada no software STATA 14.0, envolveu o uso da regressão múltipla ajustada para o efeito cluster dos estados. Um único modelo de regressão foi construído, considerando sexo e idade como covariáveis, e intervalo de confiança de 95%. Em média, os participantes apresentaram IMC normoponderal. O maior volume de treinamento foi verificado para corredores do estado de Tocantins (43,5±5,8 km/semana). Maiores valores para iluminação pública, pavimentação, calçadas e espaços verdes foram verificados para Tocantins, Amazonas e Amapá, respectivamente. A análise de regressão ajustada para o efeito do estado indicou associação direta e significativa entre ambiente e treinamento (pavimentação – B: 0,35; 95%CI: 0,33 – 0,37; calçada – B: 0,14; 95%CI: 0,11 – 0,17; arborização – B: 0,15; 95%CI: 0,14; 95%CI: 0,12 – 0,18), porém, relação inversa foi verificada para a variável iluminação (B: -0,37; 95%CI: -0,55 - -0,18). Possuir um ambiente “amigável” pode potencializar o envolvimento na prática de corrida de rua, e contribuir para o aumento dos níveis de AF dos residentes na região norte.

Published: December 2023

Background:

There are few methods for accurately assessing the risk of total hip arthroplasty (THA) in patients with osteoarthritis. A novel and reliable method that could play a substantial role in research and clinical routine should be investigated. The purpose of the present study was to develop a deep-learning model that can reliably predict the risk of THA with use of radiographic images and clinical symptom data.

Methods:

This retrospective, multicenter, case-control study assessed hip joints on weighted-bearing anteroposterior pelvic radiographs obtained from Osteoarthritis Initiative (OAI) participants. Participants who underwent THA were matched to controls according to age, sex, body mass index, and ethnicity. Cases and controls were uniformly split into training, validation, and testing data sets at proportions of 72% (n = 528), 14% (n = 104), and 14% (n = 104), respectively. Images and clinical symptom data were passed through a detection model and a deep convolutional neural network (DCNN) model to predict the probability of THA within 9 years as well as the most likely time period for THA (0 to 2 years, 3 to 5 years, 6 to 9 years). Model performance was assessed with use of the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, and specificity in the testing set.

Results:

A total of 736 participants were evaluated, including 184 cases and 552 controls. The prediction model achieved an overall accuracy, sensitivity, and specificity of 91.35%, 92.59% and 86.96%, respectively, with an AUC of 0.944, for THA within 9 years. The AUC of the DCNN model for assessing the most likely time period was 0.907 for 0 to 2 years, 0.916 for 3 to 5 years, and 0.841 for 6 to 9 years. Gradient-weighted class activation mapping closely corresponded to regions affecting the prediction of the DCNN model.

Conclusions:

The proposed DCNN model is a reliable and valid method to predict the probability of THA—within limitations. It could assist clinicians in patient counseling and decision-making regarding the timing of the intervention. In the future, by increasing the size of the data set, enhancing the ethnic and socioeconomic diversity of the participants, and improving the follow-up rate, the quality of the conclusions can be further improved.
