Published: May 2021

This study was carried out in the year November 2020. The general objective of this study was to assess the profitability and Technical efficiency of soybean producers in the municipality of Tanguiéta. A survey of a sample of 184 producers was selected at random in Center of Tanguiéta, Taïacou, Cotiakou, N’Dahonta and Tanongou of the municipality. In order to analyze the financial profitability of soybean production, the interviews focused on data in order to estimate the technical efficiency scores of each producer and to establish the operating account of the sampled producers. Thus, the most efficient and the average or weakly efficient producers whose technical efficiency scores are less than or equal to 50%. Gross margin, yield, value added per hectare and profit to production cost ratio were estimated. The results showed that the technical efficiency indices of the producers surveyed varied between 11% and 91.1% with an average of 45.62%. Soybean production is financially profitable depending on the level of technical efficiency although the yields obtained are very low for each of the groups. The profit to cost of production ratio revealed that the group of the most efficient producers has the best ratio (1.18> 0.93), showing that soybean producers are technically inefficient overall. With regard to the indicators, they are far from the production potential expected in Benin.

This case was recorded at the Faculty of Veterinary Medicine, University of Wijaya Kusuma Surabaya. Oreo cats were found with a state of weakness, severe dehydration, and a lump in the lower abdomen. The results of the physical examination of Oreo cats were diagnosed as having a mammary carcinoma, with a differential diagnosis of inguinal hernia, and mastitis. To confirm the diagnosis, blood tests and X-ray supporting examinations are carried out. From the results of the examination, the results of the blood check showed normal results, but on the X-Ray examination, there was an intermediate opacity on the part of the bulge and no ring was found that led to the hernia diagnosis. The consistency of the bulge at the time of the xray was slightly changed when compared to when the cat was found, where the consistency of the bulge became slightly flaccid accompanied by a yellowish-white discharge from the oreo cat's nipples. Based on the x-ray results that show the presence of intermediate colored opacity and the discharge of cloudy yellow milk, it can be concluded that the Oreo cat has chronic mastitis. Surgery and removal of the mammary glands (mastectomy) are still the best treatment options. In a mastectomy, the incision is performed in an ellipse, prepared from the surrounding tissue, then the nipple is removed.).

Authors: Matulessy Esther Ria
Published: May 2021

This study discusses the comparison of forecasting time series data between the Autoregressive Integrated Moving Average (ARIMA) method and the multi input transfer function model. ARIMA method is one of the most frequently used methods for forecasting time series data. Meanwhile, the transfer function model is a combination of the characteristics of multiple regression analysis with the characteristics of the ARIMA time series. Meanwhile, the multi input transfer function model is a transfer function model that has input variables of more than two time series. The application of these two methods is carried out on rainfall data from January 2012 to December 2017 in Manokwari Regency, West Papua Province. The input variables used are temperature, humidity, solar radiation, air pressure, and wind speed variables. The results showed the best ARIMA model was ARIMA (1,0,0) (2,0,0) 12 with an AIC value of 910.07, while for the best multi input transfer function model was ARIMA (1,1,0) AIC value of 898.24. Between the two methods, the best model used to forecast rainfall in Manokwari Regency, West Papua Province is the multi-input transfer function model (1,1,0).

Earthquakes are one of the main hazards in West Papua. Based on information from the National Disaster Management Authority (BNPB), the frequency of the destroyed earthquakes in West Papua is more than 9 times from 2002 until 2015. Peak Ground Acceleration (PGA) is one factor that caused destroy on earthquakes. This parameter has been used in this research to estimate the level of earthquakes hazard in West Papua at any period that combined with Point Source analysis and Gumbel distributions method. Seismic data recording of 1970 – 2017 that obtained from Meteorological, Climatological, and Geophysical Agency (BMKG) and United States Geological Survey (USGS) used in this research. The research shows that the level of earthquakes in West Papua is lower to the middle because the PGA value is < 0,70 g at any period. Generally, the level of earthquakes hazards in the north area more higher than in other areas because of some of the fault in the north area.

Authors: Pamuji Khristian Enggar
Published: May 2021

Salah satu atribut dalan NKT adalah Kawasan yang memberikan jasa ekosistem dasar pada situasi yang kritis atau sangat penting. Suatu wilayah dapat dipertimbangkan sebagai NKT 4 jika berperan dalam melindungi atau menyediakan jasa ekosistem mendasar dalam situasi penting, termasuk perlindungan daerah tangkapan air dan kontrol erosi pada tanah rentan dan lereng. Saat ini telah dilakukan penilaian keberadaan NKT 4 Daerah Aliran Sungai (DAS) Wafor yang berada di Distrik Supiori Timur, Kabupaten Supiori, Provinsi Papua. Sungai-sungai di DAS Wafor dimanfaatkan oleh masyarakat lokal sebagai sumber air bersih. Sungai Wafor memiliki rasio relief rata-rata antara 0.04, namum dibeberapa tempat terutama bagian hulu, kemiringan lereng mencapai 30%-40%. Faktor bentuk (Form factor/ Rf) DAS Wafor memiliki nilai 0.62 atau bentuk DAS relatif membulat dan rasio elongasi sebesar 0.71. Daerah aliran sungai yang membulat, debit puncak datangnya lama, begitu juga penurunannya, sehingga dapat efektif dalam mengendalikan banjir.DAS Wafor memiliki kerapatan drainase (Dd) 1,03 km/km2, artinya setiap 1 km2 area DAS terpadat panjang total sungai 1,03 km. Kerapatan drainase ini termasuk kategori sedang. Hal ini tentunya akan sangat membantu dalam menghalangi penyebaran titik-titik api jika terjadi kebakaran hutan. Sedimentasi di Sungai Wafor termasuk kategori rendah atau < 50 mg/L. Dengan alur sungai rata-rata tidak lebih dari 20 km, maka dapat disimpulkan bahwa DAS tersebut bekerja efektif dalam mengendalikan erosi.

Differential expression of solute carrier family 22 member 3 in cancers of the breast.
Authors: Mamoor Shahan
Published: May 2021

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding solute carrier family 22 member 3, SLC22A3, when comparing primary tumors of the breast to the tissue of origin, the normal breast. SLC22A3 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of SLC22A3 in primary tumors of the breast was correlated with overall survival in patients with basal and luminal B subtype breast cancer, but not in patients with luminal A or HER2+ breast cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype. SLC22A3 may be of relevance to initiation, maintenance or progression of cancers of the female breast.

Published: May 2021

A correct simulation of the dispersion during wintertime thermal inversion is important not only to improve the physical understanding of the phenomena but also to design and evaluate strategies to improve air quality. In Part II of this study the simulations performed in Part I using WRF with the multilayer urban canopy scheme BEP-BEM, are used to simulate the dispersion during one of those episodes over Madrid, Spain, using a passive tracer representing NOx. The results are compared against NOx measurements obtained at 24 ground stations, grouped in 5 zones. Coherently with Part I, the analysis shows that the best results for dispersion are obtained when BEP-BEM is used and the soil moisture is reduced to 25% of the value provided by the global model. The results also show a strong spatial variability of dispersive conditions, with a tendency of the pollutants to accumulate in the topographical depressions. Furthermore, a simple methodology is proposed to derive NO2 from NOx concentrations based on an empirical fitting of two months of observations. The statistical indicators for NO2 computed in this way are similar to those obtained with photochemical models, making this approach a valid, and computationally efficient, alternative, in particular for forecasting purposes. In the last part of this contribution, the model is used to design and evaluate simple air pollution reduction strategies. In particular, it has been found that: 1) there is no pollutant accumulation from one day to the following one, so the air quality of one day is entirely determined by the emissions and meteorological conditions of that day, 2) displacing part of the emissions of the rush hours to the central hours of the day, when the dispersive conditions are more favorable, can significantly reduce the peaks, and to a lesser extent the daily mean, without changing the total amount of pollutants emitted.

Published: May 2021

Decreasing the intensity of exercise at the end of a session has been associated with greater post-exercise pleasure and enjoyment. Here, we investigated whether this manipulation can enhance affective attitudes toward physical activity (PA) and promotes PA in patients with Parkinson’s disease (PD). Seven patients (72.9±5.6 years, 3 women) were included in an eight-week within-subject study consisting of weekly exercise sessions. The first four weeks were used as a control condition. In the last four weeks, ten minutes of lower-intensity exercise were added at the end of each session (experimental condition). Results of the linear mixed-effects models showed that the addition of lower-intensity exercise increased the explicit affective attitudes toward PA (b = 1.00, 95% Confidence Interval = .36 to 1.64, p = .022). We found no evidence of an effect on implicit affective attitudes (p = .564), accelerometer-based PA (p = .417) and self-reported PA (p = .122) measures of PA. Although not significant, self-reported physical activity per day was 36 minutes longer in the intervention than in the control condition. These findings suggest that consistently reducing the intensity of an exercise at the end of the sessions enhances explicit affective attitudes toward PA in patients with PD.

We evaluate whether the temporary pause of the Johnson & Johnson vaccine on April 13 negatively affected vaccine attitudes. We find no evidence that the pause affected vaccine intentions. However, the rapid rate of vaccinations has largely exhausted the number of vaccine enthusiastic people, likely driving the current slow down in vaccination rates.
Differential expression of vitrin in cancers of the breast.
Authors: Mamoor Shahan
Published: May 2021

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding vitrin, VIT, when comparing primary tumors of the breast to the tissue of origin, the normal breast. VIT was also differentially expressed in the tumor cells of patients with triple negative breast cancer. VIT mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of VIT in primary tumors of the breast was correlated with recurrence-free survival in patients with luminal A subtype cancer and luminal B subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype. VIT may be of relevance to initiation, maintenance or progression of cancers of the female breast.

The rapid spread of COVID-19 and the increasing burden on mental health and well- being require new ways of supporting families that have to maintain the new norms of social distancing. Many families may be under enormous amounts of stress and anxiety caused by losing their loved ones. Therefore, there is a great need to search for ways to minimize the effects of COVID-19 on mental health and well-being. The purpose of the research is to evaluate a yoga intervention offered online to school-aged children in the U.K. by Patanjali Yog Peeth Trust U.K. (PYPT) and evaluate its effectiveness by interviewing the parents of participating children. The project will seek to promote an additional tool in managing mental health and well-being in school-aged children. The research will use a mixed-methods approach. Parents will be approached by a PYPT yoga teacher and invited to complete an online survey and quantitative interview. Parents (over 18 years) of school-aged children (5-16 years) who live in the U.K. are eligible to take part. Upon gaining consent, participates will be asked to complete a parent and child characteristic questionnaire. An SDQ survey for parents via online Opinio and a subsample will be interviewed using a structured interview schedule. All analyses will be carried out in SPSS. It is intended that the research will provide an evidence base that will aid future studies and inform in developing yoga interventions that may aid in promoting child mental health and well-being. The study results will be published in peer-reviewed international journals; the researchers will also present the results at governmental conferences.

The COVID-19 pandemic is a global health problem affecting around 213 countries and territories worldwide, with more than 6,474,200 cases reported and 382,914 deaths documented so far. The World Health Organization announced COVID-19 is a pandemic outbreak on 11 March, 2020. We are facing a medical emergency because of COVID-19 pandemic. These large incidents have negative and detrimental effects on mental health and well-being of individuals worldwide. Widespread infectious disease outbreaks such as COVID-19 are linked to mental illness symptoms and psychological distress. Preliminary studies indicate that depression (28%) and anxiety (16%) symptoms and self-reported stress (8 %) are typical psychological responses to the COVID-19 pandemic, which could be correlated with sleep disturbance. The physical and psychological wellbeing of general people, particularly health care practitioners, has been profoundly affected by illness. The main objective of this review-based study is to focus mental health and psychological interventions which can be provided during this pandemic. Stress, fear, anxiety, panic, frustration is very common during COVID-19 pandemic and these can be reduced by some psychological intervention measures.

La metodología fue de diseño no experimental, de corte trasversal y de alcancecorrelacional. Los instrumentos que se utilizaron fueron la Escala de Riesgo de Adicciónadolescente a las Redes Sociales e Internet (ERA-RSI) según Montserrat Peris, CarmenMaganto y Maite Garaigordobil, adaptada por los mismos autores de la realización de laprueba y la Escala de Depresión para adolescentes de Reynolds (EDAR) según WilliamReynolds, en la versión adaptada por Ugarriza y Escurra, (2002). Los participantes fueron200 estudiantes que sus edades oscilaban de 11 a 19 años. Los resultados indicaron unarelación altamente significativa entre adicción a las redes sociales y sintomatologíadepresiva, esto significa que, los adolescentes con mayor acceso y uso de las redes socialesmostrarán mayor sintomatología depresiva. Asimismo, se encontró relación altamentesignificativa entre sintomatología depresiva y las dimensiones de nomofobia (rho =.543, p= ,00), uso social (rho=.536, p = ,00) y síntomas adicción (rho=.591, p = ,00). Por otro lado,no se encontró relación significativa entre sintomatología depresiva y la dimensión rasgosfrikis (rho =.355, p = ,231).
Individual narcissism, need for closure and the two sides of negative partisanship
Authors: Mayer Sabrina Jasmin
Published: May 2021

Usual studies of the underpinnings of partisan attachments only consider positive party identifications and the Big Five framework. However, negative party identification is an important understudied side of party identification that affects democratic dissatisfaction and political conflict. This article studies how narcissistic admiration and rivalry as well as need for closure affect negative party identification and partisanship types, such as being a negative, open, or closed partisan. I argue that different types of partisan attachments fulfill different psychological needs and the kind of attachments individuals show can thus be traced back to their personality features. Based on a novel online quota survey from Germany conducted in February and May 2021 (N= 1,454), I find narcissistic rivalry and need for closure to be central traits for different types of partisanship. Furthermore, negative partisans against a radical-right party show a different profile from partisans with other system parties.

Theophylline, theobromine and caffeine, are purine-based alkaloids in which the main differentiation in the molecular structure is the presence of methyls, one, two and three, respectively in these substances. This study presents an analysis by XRD and molecular modeling methods of the alkaloid’s caffeine and theobromine. The crystalline structure of caffeine was characterized as a monoclinic system, and the diffractogram of the caffeine crystals showed peaks with regions of greater intensity at 2θ = 11.7616 ° (d = 7.51 Å; I% = 80.13) and 2θ = 11.9416 ° (d = 7.40 Å; I% = 98.14). In the diffractogram of the theobromine crystal sample, peaks of greater intensity occurred in the regions 2θ = 13.4616 ° (d = 6.57 Å; I% = 98.92) and 2θ = 27.0816 ° (d = 3, 28 Å; I% = 67.23). Results obtained by XRD for caffeine and theobromine were compatible with standard cards of the X’Pert High Score Plus® program. The presence of an extra methyl in the structure of the caffeine purine base, suggests, a shift in the values ​​of the angle 2 θ for the main peaks of theobromine, as well as an increase in intensity, mainly in 27.016, theobromine also presents a peak in the region 10.6 which does not occur in caffeine. Statistical results reveal that the linear models for data of peaks of specific angles in 2θ of the samples, presented good linear correlation (R2> 98%) and satisfactory results after the procedure of cross validation. caffeine and theobromine also showed important differences in interactions with adenosine A2AR, particularly in hydrophobic and hydrogen interactions.

Hypospadias is one of the most common birth defects among male children. Many associated risks for hypospadias have been reported like family history, older maternal age, nulliparity, high pre-pregnancy body mass index of mother, hypertension or preeclampsia, multiple gestations, low birth weight, and small for gestational age. In literature twinning as a risk factor has been consistently shown to be associated with hypospadias. We report a 2-year-old male child (one of the twins) who presented with proximal microphallic hypospadias.

Manifestations of agrophysical degradation, first of all, soil compaction and loss of structure, remain an urgent issue for Ukrainian chernozems. With increased anthropogenic pressure on soils, these processes only spread and therefore it is very important to find tillage systems and technologies that would reduce the negative impact on soils. The main areas that reduce the intensity of degradation processes in soils are the minimization of tillage and biologization of agriculture. Intensive tillage has led to accelerated mineralization of organic matter and as a consequence of reducing its content consumption of soil structure, and hence the deterioration of its water, air, heat and microbiological regimes. The reasons for the deterioration of the physical properties of the soil are the use of agricultural machinery, intensive tillage, a significant reduction in land reclamation, especially organic fertilizers, a significant share in crop rotations of row crops and almost complete absence of perennial grasses. At the same time, maintaining physical properties in the optimal range of values is a necessary condition for obtaining the planned return from fertilizers, ameliorants and water, the cost of which is currently very high. In the system of agrotechnical measures aimed at increasing soil fertility and crop productivity, rational mechanical tillage is of great importance, which regulates agrophysical, biological and agrochemical processes occurring in the soil, the intensity of decomposition and accumulation of organic matter, content root-containing layer and effective use of fertilizers applied by plants. Studies have shown the improvement of the parameters of physical properties of soils while minimizing their cultivation. Obviously, for the successful application of minimum tillage technologies, the soil must have physical properties that are close to optimal for most crops. That is why the study of the impact of soil-protective agricultural techniques on porosity and other indicators of physical properties is relevant for specific soil and climatic conditions.
