Sebagian besar masyarakat Desa Tlogohaji merupakan petani bawang merah. Namun, perekonomian masyarakat tersebut masih berada pada tingkat menengah ke bawah. Hal tersebut disebabkan salah satunya ialah masyarakat belum bisa mengolah hasil pertanian bawang merah yang dipanen sehingga masyarakat yang sebagian besar adalah petani tersebut langsung menjualnya ke pengepul. Di sisi lain, potensi tersebut seharusnya dapat dijadikan peluang untuk dikembangkan sehingga dapat meningkatkan kesejahteraan masyarakat melalui olah produk hasil pertanian bawang merah. Oleh sebab itu, kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan wawasan dan keterampilan masyarakat melalui kegiatan pemberdayaan masyarakat Desa Tlogohaji Kecamatan Sumberrejo Kabupaten Bojonegoro dalam mengembangkan desa agroindustri bawang merah melalui kegiatan program holistik pembinaan dan pemberdayaan desa (PHP2D) tahun 2021. Metode yang dilakukan dalam kegiatan pemberdayaan masyarakat melalui PHP2D, meliputi kegiatan sosialisasi pengembangan desa agroindustri, pelatihan/penyuluhan budidaya bawang merah, pengolahan bawang merah, pemasaran produk olahan bawang merah, dan pengolahan limbah kulit bawang merah. Kegiatan tersebut melibatkan perangkat desa, PKK, Karang Taruna, BUMDes, serta masyarakat kelompok petani bawang merah. Berdasarkan kegiatan yang dilakukan, hasil yang didapatkan melalui kegiatan tersebut menunjukkan bahwa sebanyak 70% masyarakat yang mengikuti kegiatan telah memiliki pemahaman dan keterampilan dalam pengembangan desa agroindustri. Ketercapaian tujuan kegiatan juga ditunjukkan masyarakat melalui meningkatnya antusias dan motivasi yang positif dalam mengolah bawang merah hasil pertanian menjadi berbagai jenis produk sebagai salah satu indikator pengembangan desa agroindustri. Selain itu, masyarakat telah memiliki wawasan dan keterampilan dalam mengolah sampai dengan mengemas produk olahan bawang merah, seperti bawang goreng, sambal bawang, serta bawang bubuk. Hal tersebut kemudian dimanfaatkan untuk memasarkan produk olahan bawang merang yang telah diproduksi, baik secara online maupun dipasarkan secara langsung.  Dengan demikian, kegiatan pemberdayaan masyarakat yang dilakukan telah terlaksana dengan baik sesuai tujuan yang diharapkan, yakni memberdayakan masyarakat Desa Tlogohaji Kecamatan Sumberrejo Kabupaten Bojonegoro sehingga memiliki wawasan dan keterampilan untuk mengolah serta memasarkan hasil pengolahan bawang merah.

Soil nutrient management plays an important role in maintaining sustainable soil health for the future generation. The state or innate ability of the soil to provide nutrients to plants in sufficient quantities and the right proportions is known as soil fertility. Sustainable Soil fertility was maintained by following proper nutrient management by following four R’s such as the Right quantity of fertilizers at the Right time with the Right source and the Right placement. The prime first step toward sustainable farming is using an optimal amount of fertilizers as well as following the cropping pattern as per the scientific recommendation. The multinomial logit model was used to predict a nominal dependent variable in this study (SPSS version 28). In the outcome of the model, it can be observed that age, education, livestock, family size, cultivated area, distance to fertility material sources, level of soil fertility severity of soil nutrient depletion, tenure, recommended dose, residual effect and soil conservation measures are significantly contributing meaningfully to the model. Gender and awareness of soil fertilizer pollution show a negative effect on the choice of soil fertility management choices. If the farmers in the study area use integrated soil nutrient or fertility management compared with other nutrient management choices, sustainable use and management of agricultural land will be promoted. Using Soil Health Card promotes balanced use of nutrient sources by avoiding dumping or reducing the usage of fertility or nutrient sources.
Theoretical and computational studies on the optimal positions of NACA airfoils used in horizontal axis wind turbine blades
Authors: TEFERA Getahun , BRİGHT Glen , ADALİ Sarp
Published: September 2022

This paper presents a theoretical and computational study to determine the optimal positions of airfoils along the length of the horizontal axis wind turbine blade. We used four and five-digit NACA airfoils to model a 54-meter blade. The lift, drag coefficient, and lift-to-drag ratio of each airfoil are determined by using QBlade software. The aerodynamic performance of the airfoils is studied based on the blade element momentum theory, and Matlab software is used for numerical implementation. The velocity and pressure distributions on each airfoil are assessed using computational fluid dynamics. We implement the thickness distribution techniques to adjust the positions of the airfoils along the length of the blade. It is noted that stresses reach their maximum values at the root and minimum at the tip section. Thus, the thicker (NACA 4420) and thinner (NACA 23012) airfoils are set at 20% of the maximum chord and 91.11% at the tip sections of the blades. The remaining sections of the blade are configured using linear interpolation methods. Specifically, the maximum chord length of the new design is reduced by 18.06% compared to the NACA 23012 rotor blade. Finally, the recommended tip speed ratio for the designed rotor blade is estimated using the graphs of the normal and tangential forces, thereby producing a safe and efficient design.

Ketersediaan infrastruktur jalan merupakan salah satu hal penting dalam menunjang pertumbuhan ekonomi di Indonesia, sehingga diperlukan peningkatan kualitas dan kuantitas jalan agar dapat memenuhi kebutuhan masyarakat. Penggunaan material tambahan seperti filler gypsum dan aspal modifikasi polimer diharapkan dapat meningkatkan kinerja dari perkerasan jalan tersebut. Dalam penelitian ini akan membahas bagaimana penggunaan bubuk gypsum yang digunakan sebagai filler pada campuran lataston (HRS-WC) dengan menggunakan aspal modifikasi polimer. Pengujian dilakukan dengan metode Marshall variasi yang digunakan untuk kadar filler bubuk gypsum adalah 0%, 1%, 2%, dan 3% dengan kadar aspal yang digunakan adalah 6%, 6,5%, 7%, 7,5% dan 8%. Berdasarkan hasil pengujian bahwa karakteristik volumetrik campuran aspal beton dengan penambahan persentase bubuk gypsum sebagai filler meningkatkan nilai rongga dalam agregat dan rongga dalam campuran, sebaliknya untuk nilai rongga terisi aspal menjadi berkurang. Sedangkan untuk nilai stabilitas dan flow mengalami penurunan, sehingga didapatkan nilai optimum persentase filler gypsum 1% yang memberikan durabilitas lebih baik dibandingkan dengan campuran tanpa menggunakan filler gypsum.

Commercio e cittadinanza nei quartieri 167 italiani. Alcune note di ricerca
Authors: De Pieri Filippo
Published: September 2022

L’articolo riflette sugli immaginari legati al commercio a partire da una ricerca in corso sulla pianificazione e realizzazione dei quartieri PEEP italiani. La legge 167 (1962) e una serie di provvedimenti successivi rappresentarono, nelle intenzioni dei loro promotori, un momento fondativo per la costruzione di una nuova generazione di quartieri a grande scala capaci di generare nuove forme di urbanità. Quale ruolo ebbe il commercio all’interno di un simile processo? Appoggiandosi a un piccolo numero di studi di caso, la ricerca enuncia l’ipotesi che portare il fuoco dell’osservazione sulla questione del commercio permetta di cogliere alcuni dei nodi irrisolti dietro le sperimentazioni del secondo dopoguerra intorno alla “grande dimensione”. A differenza di quanto accaduto in diverse esperienze internazionali del periodo nel campo dell’urban design, le culture architettoniche e urbanistiche italiane faticarono a riconoscere nell’emergente dimensione del consumo di massa il possibile fondamento di nuove forme di socialità e di cittadinanza.

The article reflects on the images related to commerce, taking the lead from ongoing research on the planning and implementation of Italian PEEP (Plans for Economic and Public Housing) schemes. In the intentions of their promoters, Law 167 (1962) and a series of subsequent measures represented a founding moment for the construction of a new generation of large-scale residential neighborhoods capable of generating new forms of urbanity. What role did commerce play within such a process? Relying on a small number of case studies, the research formulates the hypothesis that focusing on the issue of commerce allows us to address some of the unresolved questions behind the post-World War II experiments around the issue of the grande dimensione (‘great dimension’). Unlike several international experiences of the time in the field of urban design, Italian architectural and urban cultures struggled to recognize in the emerging mass consumption the possible foundation of new forms of sociality and citizenship.

Published: September 2022

This study aims to examine the opinions of prospective teachers studying at the faculty of sports sciences about combat sports according to various variables. For this purpose, the “Attitude Scale towards Fighting Sports” created by Kayapınar et al. in 2016 was used. The population of the research consists of 1330 students studying at Trakya University Kırkpınar Faculty of Sports Sciences. The confidence interval of the study was considered 95% (p < 0.05). A total of 343 teacher candidates were reached by random sampling method. According to the "gender and training year" variables of the sample group, the scores they got from the Attitude Scale towards Fighting Sports were analyzed using the SPSS 25.0 package program. The normality distributions of the data were examined by examining the kurtosis and skewness values. Cronbach Alpha value was used in the reliability calculation of the dimensions. The Mann-Whitney U test was used to analyze the "gender" variable, one of the independent variables of the research, and the Kruskal-Wallis test for the "training year" variable. Rosenthal formula (r=Z/√N) was used to calculate the effect size of the meaningful results obtained with the test statistics. The effect sizes of the tests with statistically significant difference (p < 0.05) were calculated. As a result, significant difference was found in the "satisfaction" sub-dimension of the research scale according to the gender variable, and in the pleasure, incentive and all scale dimensions according to the athlete's background (p < 0.05).

Introdução: A alta incidência de colelitíase e coledocolitíase está associada à rápida perda de peso alcançada pela cirurgia bariátrica. No entanto, o acesso à árvore biliar pode ser muito desafiador para cirurgiões e endoscopistas após um bypass gástrico. Relato do caso: Uma paciente de 66 anos de idade, com história de bypass gástrico de anastomose única, recorreu ao serviço de urgência com coledocolitíase. Devido à anatomia gastrointestinal distorcida, o acesso convencional à árvore biliar não foi possível. A paciente foi submetida a colangiopancreatografia endoscópica retrógrada (CPRE) transgástrica assistida por laparoscopia, na qual um endoscópio é introduzido no estômago excluído por via laparoscópica. A cirurgia é descrita passo a passo a seguir. Nenhuma complicação foi registrada. Conclusão: Este procedimento está a tornar-se mais comum devido ao aumento do número de cirurgias bariátricas. Este caso mostrou que a técnica descrita é simples, segura e viável, mesmo em hospitais secundários, com o benefício adicional de permitir tratamento endoscópico e colecistectomia ao mesmo tempo.

Differential expression of APOE in amyotrophic lateral sclerosis.
Authors: Mamoor Shahan
Published: September 2022

Neurodegenerative diseases that affect the motor neurons, including amyotrophic lateral sclerosis (ALS), have little treatment options and are generally rapidly fatal (1, 2). We harnessed the power of unbiased, whole transcriptome differential gene expression analysis, utilizing primary patient cells and tissues to discover genes whose expression defines sporadic ALS using published data (3, 4). We found significant differential expression of APOE, encoding apolipoprotein E, in primary motor neurons of patients with ALS. APOE was also differentially expressed in the fibroblasts isolated from patients with ALS. APOE transcript was present at significantly higher levels in ALS patient fibroblasts as compared to control, non-diseased fibroblasts. These analyses will begin to define the transcriptional landscape of ALS.
Invasive species have their invasion limits
Authors: Mindsponge AISDL
Published: September 2022

Biodiversity loss is happening at an unprecedented rate, and invasive species are one of the main contributors to the global biodiversity decline. Invasive species are alien (non-native) organisms that become overpopulated and cause environmental harm to the native environment. For example, a recent global meta-analysis shows that 30 invasive predator species have been linked to the extinction or endangerment of 738 vertebrate species, accounting for 58% of all bird, mammal, and reptile extinctions. For effective biology conservation, some questions are worth answering: Do invasive species have any invasion limits? Or are they capable of invading habitats significantly different from their native environment due to their strong adaptability?

Neurodegenerative diseases that affect the motor neurons, including amyotrophic lateral sclerosis (ALS), have little treatment options and are generally rapidly fatal (1, 2). We harnessed the power of unbiased, whole transcriptome differential gene expression analysis, utilizing primary patient cells and tissues to discover genes whose expression defines ALS using published data (3, 4). We found significant differential expression of RGS1, encoding regulator of G-protein signaling 1, in the primary motor neurons of patients with ALS. RGS1 was also differentially expressed in the skeletal muscle of patients with ALS. RGS1 transcript was present at significantly higher levels in ALS patient motor neurons as compared to control motor neurons. These analyses will begin to define the transcriptional landscape of ALS.
Considering the Role of Guidelines in Visualization Design Practice
Authors: Parsons Paul C , Shukla Prakash Chandra
Published: September 2022

Guidelines are commonly viewed as an important form of design knowledge that can support the principled application of research findings to visualization design. Researchers regularly propose design guidelines as outputs from studies with the aim of prescribing design activity. However, inquiry into the actual use of design guidelines by practitioners is often unaddressed or left for future work. We propose there is a need for visualization researchers to better understand the realities of design practice, especially its epistemological foundations, and how different forms of design knowledge are actually employed rather than how researchers imagine them to be employed.

Communication & deniability: Moral and epistemic reactions to denials
Authors: Bonalumi Francesca , Bumin Feride Belma , Scott-Phillips Thom , Heintz Christophe
Published: September 2022

People often deny having meant what the audience understood. Such denials occur in both interpersonal and institutional contexts, such as in political discourse, the interpretation of laws and the perception of lies. In practice, denials have a wide range of possible effects on the audience, such as conversational repair, reinterpretation of the original utterance, moral judgements about the speaker, and rejection of the denial. When are these different reactions triggered? What factors make denials credible? There are surprisingly few experimental studies directly targeting such questions. Here, we present two pre-registered experiments focusing on (i) the speaker’s incentives to mislead their audience, and (ii) the impact of speaker denials on audiences’ moral and epistemic assessments of what has been said. We find that the extent to which speakers are judged responsible for the audience’s interpretations is modulated by their (the speakers’) incentives to mislead, but not by denials themselves. We also find that people are more willing than we expected to revise their interpretation of the speaker’s utterance when they learn that the ascribed meaning is false, regardless of whether the speaker is known to have had incentives to deceive their audience. In general, these findings are consistent with the idea that communicators are held responsible for the cognitive effects they trigger in their audience; rather than being responsible for, more narrowly, only the effects of what was ‘literally’ said. In light of our findings, we present a new, cognitive analysis of how audiences react to denials, drawing in particular on the Relevance Theory approach to communication. We distinguish in particular: (a) the spontaneous and intuitive re-interpretation of the original utterance in light of a denial; (b) the attribution of responsibility to the speaker for the cognitive effects of what is communicated; and (c) the reflective attribution of a particular intention to the speaker, which include argumentative considerations, higher-order deniability and reputational concerns. Existing experimental work, including our own, aims mostly at (a) and (b), and does not adequately control for (c). Deeper understanding of what can be credibly denied will be hindered unless and until this methodological problem is resolved.

Purpose: This study examined the extent to which acoustic, linguistic, and cognitive task demands interactively impact listening effort. Method: Using a dual-task paradigm, on each trial, participants were instructed to perform either a single task or two tasks. In the primary word recognition task, participants repeated NU-6 words presented in speech-shaped noise at either an easier or a harder signal-to-noise ratio (SNR). The words varied in how commonly they occur in the English language (lexical frequency). In the secondary visual task, participants were instructed to press a specific key as soon as a number appeared on screen (simpler task) or one of two keys to indicate whether the visualized number was even or odd (more complex task). Results: Manipulation checks revealed that key assumptions of the dual-task design were met. A significant three-way interaction was observed, such that the expected effect of SNR on effort was only observable for words with lower lexical frequency and only when multitasking demands were relatively simpler.Conclusions: This work reveals that variability across speech stimuli can influence the sensitivity of the dual-task paradigm for detecting changes in listening effort. In line with previous work, the results of this study also suggest that higher cognitive demands may limit the ability to detect expected effects of SNR on measures of effort. With implications for real-world listening, these findings highlight that even relatively minor changes in lexical and multitasking demands can alter the effort devoted to listening in noise.

Large scale word association datasets are both important tools used in psycholinguistics and used as models that capture meaning when considered as semantic networks. Here we present word association norms for Rioplatense Spanish, a variant spoken in Argentina and Uruguay. The norms were derived through a large-scale crowd-sourced continued word association task in which participants give three associations to a list of cue words. Covering over 13,000 words and +3.6M responses, it is currently the most extensive dataset available for Spanish. We compare the obtained dataset with previous studies in Dutch and English to investigate the role of grammatical gender and studies that used Iberian Spanish to test generalizability to other Spanish variants. Finally, we evaluated the validity of our data in word processing (lexical decision reaction times) and semantic (similarity judgment) tasks. Our results demonstrate that network measures such as in-degree provide a good prediction of lexical decision response times. Analyzing semantic similarity judgments, showed that results replicate and extend previous findings demonstrating that semantic similarity derived using spreading activation or spectral methods outperform word embeddings trained on text corpora.

Given insufficient prospective evidence for relationships between social media use and well-being among adults, the present study examined the temporal sequence between social media use and psychological distress and life satisfaction, and explored age and gender differences. A representative sample of adults (N = 7,331; 62.4% women; Mage = 51.94; SD = 13.48; 15-94 years) were surveyed annually across four waves. Cross-lagged panel models demonstrated bidirectional relationships between social media use and well-being. Higher psychological distress and lower life satisfaction predicted higher social media use more strongly than the reverse direction, with effects particularly pronounced for the impact of psychological distress. Although the patterns of findings were relatively consistent across age and gender, results suggested that women and middle- and older-aged adults experience detrimental effects of social media use on well-being, which may drive subsequent increased use of social media. The bidirectional relationships suggest that adults who experience psychological distress or lower life satisfaction may seek to use social media as a way to alleviate poor well-being. However, paradoxically, this maladaptive coping mechanism appears to drive increased social media use which in turn can exacerbate poor well-being. Clinicians should be aware of these bidirectional relationships and work with clients towards replacing ineffective strategies with more helpful coping approaches. As this study used a simplistic measure of social media use, future research should address this limitation and explore nuanced relationships afforded by assessing specific social media activities or exposure to certain types of content.

Spontaneous intestinal perforation suggests a perforation of the gastrointestinal tract of no demonstrable cause. Only few such cases have been described in full term newborns. Although some authors have suggested ischemia and fetal or neonatal hypoxia as the most likely cause, the etiology and pathogenesis of this disease are still widely unknown. Here, we present a case of Spontaneous intestinal perforation in a full term neonate who was born to a mother with chronic hypertension. Radiological images revealed pneumoperitoneum on a three day old baby with feeding intolerance and abdominal distention. There was no clinical evidence of Hirschsprung’s disease, necrotizing enterocolitis, anorectal malformations or bowel obstruction. An emergency laparotomy revealed a localized perforation in distal ileum. Histopathological examination failed to reveal any etiology for the perforation. The neonate recovered rapidly following a double barrel ileostomy, with no immediate gastrointestinal complications.
Exploring Resilience among Elderly Widows in Nepal
Authors: Pant Poonam
Published: September 2022

Many traditional societies still lack a strong social security systems for the elderly people. They generally view elderly people living with family as dependent on the family structure for social support, health and wellbeing. However, widows lack privileges and protection even when they live in traditional joint families, with at least one child and grandchildren. In reality, their resilience plays a significant role in their health and wellbeing as they age. To identify research gap about resilience among elderly widows, this study assessed the situation of 25 elderly widows aged 65 and above residing with their families in Kathmandu district , Nepal and identified key factors bringing about resilience in their day-to-day life. The resilience index comprised of four dimensions: psychological, physical health and fitness, food and nutrition and life support. The findings indicate that financial independence and education are two critical factors that best support resilience in elderly widows. This has far-reaching impacts on vulnerable groups like elderly people, especially elderly widows. The resilience index will be helpful for policy makers, stakeholders and other researchers to study the wellbeing and resilience among older widows.

In this work, cellulose was successfully extracted from pineapple leaf waste by 0.75 M NaOH at 90oC and 5 M HNO3 at 70oC for 1.5 h and 5 h, respectively. The obtained cellulose fibres, with average diameters of 150-300 nm, were converted to carboxymethyl cellulose (CMC) by esterification. The pure cellulose was soaked in a solution mixture of isopropanol and NaOH for 2 h. It was then reacted with chloroacetic acid (MCA) at 60oC for 1.5 h. The optimum conditions for carboxymethylation were found to be 5 g cellulose, 1.5 g MCA, and 15 ml 16% w/v NaOH. The obtained CMC had a high degree of substitution (DS) of 2.3. The properties of CMC were determined.
Interaction between a complex fluid flow and a rotating cylinder

Published: September 2022

The flow of a thixotropic Bingham material past a rotating cylinder is studied under a wide range of Reynolds and Bingham numbers, thixotropic parameters, and rotational speeds. A microstructure transition of the material involving breakdown and recovery processes is modeled using a kinetic equation, and the Bingham- Papanastasiou model is employed to represent shear stress-strain rate relations. Results show that the material’s structural state at equilibrium depends greatly on the rotational speed and the thixotropic parameters. A layer around the cylinder resembling a Newtonian fluid is observed, in which the microstructure is almost completely broken, the yield stress is negligibly small, and the apparent viscosity approximates that of the Newtonian fluid. The thickness of this Newtonian-like layer varies with the rotational speed and the Reynolds number, but more significantly with the former than with the latter. In addition, the lift and moment coefficients increase with the rotational speed. These values are found to be close to those of the Newtonian fluid as well as of an equivalent non-thixotropic Bingham fluid. Many other aspects of the flow such as the flow pattern, the unyielded zones, and strain rate distribution are presented and discussed.
