Представлены результаты двухфакторного опыта, проведённого в 2009‒2013 годах на опытном поле Пензенского НИИСХ, по изучению влияния элементов технологии возделывания (бактериально-минерального питания, норм высева семян) на урожайность зелёной массы, её качество и продуктивность нового сорта донника волосистого Солнышко. Исследования проводили на чернозёме выщелоченном с высоким содержанием доступных форм азота и повышенным — фосфора и калия по общепринятым методикам. Показана эффективность применения «Ризоторфина» как отдельно, так и совместно с минеральными удобрениями (азотными и калийными) на планируемую урожайность 9 т/га сухого вещества с нормой высева 10 млн всхожих семян на 1 га при возделывании на кормовые цели. Сбор кормовых единиц в этих вариантах составил 7,81 и 8,45 т/га, переваримого протеина — 1,50 и 1,59 т/га соответственно. Питательная ценность 1 кг абсолютно сухого вещества составила по вариантам 0,72‒0,84 корм. ед., обменная энергия — 9,44‒10,16 МДж, содержание переваримого протеина в 1 корм. ед. — 179‒192 г. На качество зелёной массы донника волосистого оказывали влияние как фон питания, так и норма высева: инокуляция и внесение удобрений снижали содержание клетчатки, повышали содержание протеина; увеличение нормы высева увеличивало содержание протеина. Основное влияние на урожайность зелёной массы донника в год пользования оказывали погодные условия — 31 %, далее следовал фактор «норма высева» — 21 %, фактор «фон питания» занимал лишь 12 %. Наиболее эффективно с экономической точки зрения возделывать донник волосистый с нормой высева 10 млн всхожих семян на 1 га и инокуляцией семян без применения минеральных удобрений.

Two-factorial experiment took place on 2009‒2013 on trial field of Penza Agricultural Research Institute. It dealt with the effect of bacterium-mineral nutrition and seeding rate on green mass yield, quality and productivity of novel variety of biennial melilot “Solnyshko”. Leached chernozem of the trial field had high concentration of available nitrogen, phosphorus and potassium. Efficacy of “Rizotorfin” was revealed applied both separately and in combination with mineral fertilizers (NP) for the planned yield of 9 t dry matter ha-1. Seeding rate made up 10 million germinating seeds per ha. Feed unit yields for these variant were 7.81 and 8.45 t ha-1, digestible protein — 1.50 and 1.59 t ha-1, respectively. Nutritional value of 1 kg absolute dry matter was 0.72‒0.84 feed units, exchange energy — 9.44‒10.16 MJ, digestible protein content per 1 feed unit — 179‒192 g. Inoculation by bacteria and fertilization reduced fiber content and increased protein concentration. Increasing seeding rate raised protein amount. Green mass yield was significantly affected by weather (31 %), seeding rate (21 %) and nutritional (12 %). Melilot cultivation had the best effectiveness under seeding rate of 10 million seeds per ha and seed treatment with bacteria with zero fertilization.

В статье дан анализ качества заготовки и питательности кормов в трёх почвенно-климатических зонах Хакасии. С учётом потребности животноводства в кормах в сухостепной зоне в среднем за 2011‒2015 годы заготовлено 14 189,5 т корм. ед., в степной — 43 193,7 и лесостепной — 26 782,7 т корм. ед., средневзвешенная обеспеченность кормов на одну условную голову по Республике Хакасия — 1,98 т корм. ед., по зонам — соответственно 0,77, 2,76 и 3,24 т корм. ед. Увеличения производства продукции можно добиться за счёт улучшения качества производимых кормов. Заготовленное по зонам сено, сенаж и силос в основном относятся ко II и III классам. Больше всего неклассного сена в сухостепной зоне — 23%. Изучение химического состава кормов в течение 5 лет показало, что во всех природно-климатических зонах питательность 1 кг сена составила 0,70 ЭКЕ (энергетических кормовых единиц), сенажа — 0,30; силоса — 0,20 и зернофуража — 1,05 ЭКЕ. Установлено, что сахаро-протеиновое  отношение в сене было в пределах нормы (0,8–1,0:1,0), в остальных кормах ниже: в силосе — 0,1–0,2:1,0, в сенаже — 0,2–0,7:1,0, в зернофураже — 0,1–0,4:1,0. В рацион дойного стада необходимо включать сено многолетних злаково-бобовых травосмесей и суданскую траву, отличающуюся повышенным содержанием сахара (1,70–1,87%). Обеспеченность обменной энергией 1 кг сена составляла 8,4‒9,3 МДж, сенажа — 6,5‒6,6, силоса — 1,8–2,1 МДж обменной энергии. Получение кормов с более высоким уровнем сахара и сырого протеина является приоритетной задачей в кормопроизводстве.

The paper reports on quality and nutritional value of fodder from three edaphoclimatic zones of Khakassia. According to livestock requirements in nutrients, forage preparation in 2011‒2015 averaged to 14 189.5 t of feed units in dry steppe, 43 193.7 t — in steppe and — 26 782.7 t — in forest-steppe. Weighted mean values of forage availability for one relative head made up 1.98 t of feed units for the Republic of Khakassia and 0.77, 2.76 and 3.24 t for the zones, respectively. Increase in forage production demands improvement of feed quality. Hay, haylage and silage, obtained from the zones corresponded to II and III grades. The largest part of inedible hay occurred in dry steppe — 23%. For all the zones 1 kg of hay had 0.70 energy-feed units, haylage — 0.30; silage — 0.20 and grain fodder — 1.05 energy-feed units. Sugar-protein ratio in hay met the standard (0.8–1.0:1.0), being lower in other feeds: silage — 0.1–0.2:1.0, haylage — 0.2–0.7:1.0 and grain fodder — 0.1–0.4:1.0. Dairy cows should consume hay of perennial gramineous-legume mixtures and Sudan grass, having high sugar content (1.70–1.87%). 1 kg of hay contained 8.4‒9.3 MJ of exchange energy, haylage — 6.5‒6.6 MJ and silage — 1.8–2.1 MJ.

Эффективность производственного использования сельскохозяйственных культур во многом определяется хозяйственно полезными характеристиками используемых сортов, соблюдением агротехники возделывания и почвенно-климатическими условиями. Сорт овсяницы луговой (Festuca pratensis Huds.) Краснопоймская 92 интенсивного типа использования отличается от сортов экстенсивного (сенокосного) назначения по биологическим и хозяйственно ценным признакам. Приведены результаты изучения эффективности высокопродуктивных семенных травостоев овсяницы луговой сорта Краснопоймская 92 в условиях суходола и поймы. Установлено, что при высеве от 4 до 16 кг/га семян при ширине междурядий 15 и 30 см полнота всходов составляла 55‒68%. При этом выявлена закономерность уменьшения полноты всходов с увеличением густоты посева. В условиях суходола травостой с оптимальной густотой стояния в интервале 126‒241 шт./м2 был получен при высеве 4‒8 кг/га, или 1,8‒3,6 млн шт./га всхожих семян. Это позволило сформировать устойчивый к полеганию агрофитоценоз с высокой обсеменённостью соцветий и максимальным количеством генеративных побегов: 580‒638 шт./м2 — в первый год, 486‒606 — во второй и 413‒571 шт./м2 — в третий год пользования — и получить урожайность семян 421‒431 кг/га в среднем по трём годам. При возделывании сорта в специфичных условиях поймы создание высокопродуктивных семенных агроценозов обеспечивалось нормами высева 10‒12 кг/га при дифференцированном весеннем внесении минерального азота: в первые два года пользования — N45, в третий — N60. Урожайность семян в первый год пользования травостоя овсяницы составляла 500‒514 кг/га, во второй — 479‒554, в третий — 418‒420 кг/га.

Effectiveness of crop cultivation depends on economically important traits of a variety, growing techniques and environment. Meadow fescue (Festuca pratensis Huds.) “Krasnopoymskaya 92” for intensive management differs from the ones for extensive cultivation in biological and economical parameters. Productivity of “Krasnopoymskaya 92” was tested on a dry land and floodplain. Seeding rate from 4 to 16 kg ha-1 gave 55‒68% of germination under inter-row spacing of 15 and 30 cm. Increase in crop density negatively affected germination rate. Seeding rate of 4‒8 kg ha-1 or 1.8‒3.6 million pcs ha-1 of germinated seeds provided optimal sward density of 126‒241 pcs/m2 under dry conditions. It enabled formation of lodging-resistant ecosystems that had high amount of seeds and generative shoots: 580‒638, 486‒606 and 413‒571 pcs/m2 in the first, second and third years, respectively. Seed productivity amounted to 421‒431 pcs/m2 on the average for three years. High seed productivity on the floodplain happened as the result of the seeding rate of 10–12 kg ha-1 as well as spring fertilization by N45 in the fi rst and second years and N60 —in the third year.Seed productivities made up 500‒514, 479‒554 and 418‒420 kg ha-1 in the first, second and third years, respectively.

Представлены результаты исследований урожайности, химического состава и энергетической ценности однолетних смесей на основе овса посевного, гороха посевного и вики посевной в различные фазы вегетации растений. Исследования проведены в условиях экспериментального поля ФГБНУ «ФНЦ – ВИЖ им. Л. К. Эрнста». Агротехнические мероприятия выполнены согласно принятой для данной агроклиматической зоны технологии возделывания в системе кормового севооборота. Установлено, что содержание протеина в зелёной массе тем выше, чем больше удельный вес бобовых в травосмеси, однако такие посевы подвержены полеганию. При развитии растений в травосмесях происходят изменения химического состава: увеличивается содержание клетчатки, БЭВ, крахмала и снижается содержание сахара и каротина, при этом энергетическая ценность повышается и составляет более 9 МДж обменной энергии (ОЭ) в 1 кг сухой массы. Изучение химического состава травосмеси, скошенной на различной высоте от поверхности почвы, показало, что при повышении среза с 9 до 25 см энергетическая ценность зелёной массы увеличивается с 2,65 до 2,78 МДж ОЭ, а содержание протеина – с 48 до 60,5 г. Посев трёхкомпонентной смеси из овса, вики и гороха позволяет получить полноценную зелёную массу, энергетическую и биологическую ценность которой можно регулировать уборкой в различные фазы вегетации и высотой среза растений, что важно при кормлении высокопродуктивного молочного скота.

The paper reports on productivity, chemical composition and energy value of annual mixtures of oats, pea and vetch at various growth stages. Cultivation techniques was performed according to Standard, developed for the respective zone. The more the ratio of legumes in the mixture the higher the content of protein in green mass. However, lodging affected grasses. Variation in chemical composition happened when plant grew in grass mixtures: contents of fiber, nitrogen-free extractive substances and starch increased while sugar and carotene concentration dropped. Energy value increased and made up above 9 MJ of exchange energy in 1 kg of dry mass. When cutting height was changed from 9 to 25 cm energy value of green mass improved from 2.65 to 2.78 MJ of exchange energy, protein content — from 48 to 60.5 g. Oat-vetch-pea grass mixture gave high-quality green mass. Energy and biological value of the cut mass could be optimized by harvesting at different growth stages and variation in cutting height which is important in feeding of highly productive dairy cows.

Published: August 2022

Установлена высокая эффективность комплексного применения органических и минеральных удобрений при возделывании сельскохозяйственных культур в шестипольном кормовом севообороте на дерново-подзолистой почве. Наибольшая урожайность кормовых культур получена при внесении 80 т/га торфонавозного компоста (ТНК) + NPK. При таком соотношении удобрений получена средняя урожайность клубней картофеля 35,6 т/га, многолетних трав — 6,2 т/га и однолетних трав — 4,9 т/га сухого вещества. Качество кормовых культур значительно улучшалось при внесении повышенных доз органических и минеральных удобрений. Содержание сырого протеина в многолетних травах увеличилось до 14,7% (в контроле — 10,4%), сырого жира — до 4,4% (в контроле — 2,5%). Положительный эффект достигнут, в частности, при совместном внесении под картофель: количество крахмала в клубнях возрастало до 16,7%, что на 3,1 % выше результата, полученного в варианте без удобрений, и на 2,2% выше, чем при внесении полной дозы минеральных удобрений. Подобные закономерности отмечались и при возделывании однолетних трав. Применение органической и органоминеральной систем удобрений оказывало положительное эффект на содержание гумуса в почве. За период 1978‒2017 годов содержание гумуса повысилось на 0,7–0,9% при использовании двух доз ТНК и на 0,5–0,9% — при совместном применении органических и минеральных удобрений, тогда как при применении минеральных удобрений содержание гумуса в почве снизилось на 0,1–0,2%. В вариантах с NPK наблюдалось подкисление почвы и снижение содержания подвижного калия.

The report revealed high effectiveness of organic-mineral fertilization in six-field crop rotation on sod-podzolic soil. The highest productivity of forage crops was achieved under application of 80 t ha-1 of peat-manure compost (PMC) + NPK. This combination resulted in mean yield of potato tubers of 35.6 t ha-1, perennial grasses — 6.2 t ha-1 and annual grassed — 4.9 t ha-1 of dry matter (DM). Quality of forage crops significantly improved under high fertilizer rates. Crude protein content in perennial grasses increased up to 14.7% (control — 10.4%), crude fat — up to 4.4% (control — 2.5%). Potato fertilization by organic-mineral mixture led to increase of starch content in tubers of up to 16.7%, exceeding the non-fertilized variant by 3.1 % and the one on the background of full mineral nutrition — by 2.2%. Same trends were observed when cultivating annual grasses. Application of organic and organic-mineral fertilizers positively affected humus accumulation in soil. In the period of 1978‒2017 humus content increased by 0.7–0.9% under two rates of peat-manure compost and by 0.5–0.9% — on the background of organic-mineral fertilization; mineral fertilizers reduced humus concentration in soil by 0.1–0.2%. Variants of NPK showed soil acidification and decrease in soluble K content.

Authors: Kakarla Deepti
Published: August 2022

Demand of high-performance converters with integrated circuits with combined features and specifications of power consumption, resolution and speed have become very dominant in many emerging applications. Pipelined ADC mixed signal system consists of Sample and Hold, Flash ADC, DAC and Gain amplifier in all the stages. In the present work, a pipeline ADC architecture has 3-stages, with each stage of 3-bits with 3-bit flash ADC followed by a 3-bit binary weighted DAC at each stage. A novel approach to design a 8-bit ADC is implemented, and this design offers less number of comparators compared to flash ADC with less circuit complexity, and 8-bit ADC is designed with improvement in resolution. It is simulated first in MATLAB, but applying 1.8Volts sinusoidal and sampling time of 40 MSPS and clock frequency 10MHz the individual blocks are implemented in LT-spice 180 nm technology with bandwidth of 40 MHz. Then a high gain amplifier is implemented by using Diode connected load differential amplifier with 10mv input voltage and 18Mhz input frequency.
The Shadow Pandemic: The Exacerbation of Social Harm During The Covid-19 Crisis
Authors:   , Papesch Lennon
Published: August 2022

This thesis uses family violence in New Zealand as a case study to analyse how social harm is exacerbated during a pandemic. Traditionally social harm literature has focused on harms that are a result of state and corporate actors within capitalist economies, with little attention being given to gendered harms related to patriarchal forces within these economies. Semi-structured interviews were conducted with key workers from the family violence support sector based in Auckland, Wellington and Christchurch. Participants’ responses revealed that social harms such as poverty, lack of housing and lack of state funding for NGOs were exacerbated during the pandemic and that these harms were also related to a rise in family violence cases. In doing so, the thesis demonstrates that social harm thinking needs to be much more attentive to patriarchy and gendered power relations.
conceito de midiatização nos estudos em migrações
Authors: ZANETTI LUCAS
Published: August 2022

O presente artigo realiza pesquisa bibliográfica em teses de doutorado e dissertações de mestrado brasileiras encontradas na Biblioteca Digital Brasileira de Teses e Dissertações (BDTD) entre os anos de 2001 a 2021 que tratam das diversas relações entre mídia e migração (e suas variações terminológicas) com o objetivo de compreender como o conceito de midiatização é trabalhado nas pesquisas científicas da área de Comunicação. O trabalho também pretende mapear as pesquisas no espaço (distribuição geográfica e programas de pós-graduação das defesas) e no tempo (anos de publicação), a abordagem teórico-epistemológica no campo da Comunicação utilizadas e os autores citados que trabalham com o conceito de midiatização na América Latina e Europa. Foram encontradas 26 pesquisas entre teses e dissertações e, após análise qualitativa de cunho exploratório, notamos que o conceito de midiatização é pouco trabalhado pelos pesquisadores da área, e que esta articulação encontra campo fértil para seu desenvolvimento. Pretendemos levantar discussão que posicione a pesquisa entre mídia e migração no campo teórico da midiatização, à exemplo do trabalho de Martino (2021), com mídia e religião. À luz dos autores das teorias da midiatização, propomos a diferenciação desta relação a partir da noção de articulação (midiatização das migrações) em contraste com a perspectiva de proximidade (mídia e migração).

Authors: Cabrera Franco Tonatiuh
Published: August 2022

Desde una perspectiva cualitativa basada en un análisis documental y de contenido, en este trabajo se aborda uno de los instrumentos de la política educativa en México ante el Covid-19, la nueva asignatura Vida Saludable que comenzó a impartirse de manera remota vía televisión en Aprende en Casa II. El objetivo es por un lado describir el proceso que llevó la política desde su agenda, definición, diseño e implementación, y por el otro identificar la forma en que se entiende y enseña sobre y de salud a los niños de educación primaria. Entre los principales hallazgos se encuentran: el momento de oportunidad que posibilita la inclusión de la nueva asignatura; que se define a la salud, desde la voluntad de saber, como ausencia de enfermedad; un diseño enfocado coyunturalmente a la prevención de Covid-19 y las enfermedades asociadas a una mayor mortalidad (las cuales son de alta prevalencia en el país); y una implementación piloto que a la par del diseño trató de responder al momento epidémico. Aunque resulta un acierto incluir una asignatura dedicada exclusivamente a la salud, los cambios profundos en el tratamiento temático prometidos no se dan y se continúa medicalizando la enseñanza de la salud.

In recent years, the application of deep learning methods has become increasingly popular, especially for big data, because big data has a very large data size and needs to be predicted accurately. One of the big data is the document text data of cancer clinical trials. Clinical trials are studies of human participation in helping people's safety and health. The aim of this paper is to classify cancer clinical texts from a public data set. The proposed algorithms are Bidirectional Long Short Term Memory (BiLSTM) and Word Embedding Features (WE). This study has contributed to a new classification model for documenting clinical trials and increasing the classification performance evaluation. In this study, two experiments work are conducted, namely experimental work BiLSTM without WE, and experimental work BiLSTM using WE. The experimental results for BiLSTM without WE were accuracy = 86.2; precision = 85.5; recall = 87.3; and F-1 score = 86.4.  meanwhile the experiment results for BiLSTM using WE stated that the evaluation score showed outstanding performance in text classification, especially in clinical trial texts with accuracy = 92,3; precision = 92.2; recall = 92.9; and F-1 score = 92.5.

Photovoltaic (PV) technology is a renewable technology utilizing conversion of solar power or solar radiation into electrical energy. In the manufacture of Solar Power Generation systems, reference is needed regarding the cost of generation and scheduling of maintenance plans. To obtain this reference, it is necessary to predict the photovoltaic power output which is used to determine the power output of PV in the future. In this study, a system that is used to predict short-term power output in PV is designed. This system uses solar irradiation data and 42 days of power output in off-grid PV mini-grid as the dataset. The dataset obtained from the PV output is processed using the Support Vector Regression method with the Kernel Radial Basis Function (RBF) function. Based on the dataset used, this study succeeded in testing the best kernel, namely the RBF kernel. Evaluation of the prediction model obtained a smaller error value than other kernel tests with a Mean Absolute Percentage Error (MAPE) value of 21.082%, Mean Square Error (MSE) value of 0.122, and Mean Absolute Error (MAE) value of 0.262. The prediction model obtained is used to predict the short-term PV power output for the next 3 days. The results of the prediction model have an error value of 5.785 % for MAPE, 0.005 for MAE and 0.069 for MSE. Therefore, the predictive model can be categorized as very good and feasible to predict short-term power output

Aedes aegypti is one of the most dangerous mosquitoes that can cause several deadly diseases, such as dengue fever, Chikungunya, Zika, and jaundice with high mortality rate. For now, no specific drug has been found that can cure the disease caused by Aedes Aegypti. One possible solution for handling this problem is to inhibit the growth and development of Aedes aegypti larvae. This study aims to implement Genetic Algorithm-Support Vector Machine to develop Quantitative Structure-Activity Relationship model for identification larvicidal phytocompounds as anti-aedes-aegypti. Hyperparameter tuning was performed to improve the performance of the models. Based on the result, we found that the best model was developed by the RBF kernel with the value of    and  score are 0.64 and 0.64, respectively.

Personal protective equipment (PPE) in the COVID-19 pandemic era is essential for healthcare workers to decrease the risk of infection. The PPE, such as N95 masks and goggles, can trigger external-compression headache (ECH). This study aimed to determine the factors associated with the prevalence of ECH attributed to PPE usage. It was an analytic-observational study with a cross-sectional design conducted at Dr. M. Djamil Hospital Padang in May 2020. The subjects were healthcare workers (doctors and nurses) who used level 3 PPE for a minimum of 4 hours. The diagnosis of ECH was determined by the International Classification of Headache Disorders (ICHD) 3rd edition criteria. The Headache Screening Questionnaire (HSQ) determined the pre-existing primary headaches. The association between variables was analyzed using chi-square and Kruskal-Wallis tests. P-value<0.05 was considered statistically significant. A total of 113 healthcare workers participated in this study, consisting of 46 (40.7%) males and 67 (59.3%) females. The median age was 30 (23–46) years. ECH occurred in 102 (90.3%) respondents. Pre-existing primary headaches were present in 79 (69.9%) respondents, including migraine in 28 (23.6%) and tension-type headaches (TTH) in 46 (40.7%) respondents. The frontalis (69%) and temporalis (50.4%) were the most affected muscles. In this study, the significant factor associated with ECH was pre-existing primary headache (p=0.001, OR=7.795). There was a significant association between the pre-existing TTH (p=0.022) and ECH. There was a non-significant association between pre-existing migraine and ECH (p=0.284). In conclusion, the pre-existing primary headache was associated with the prevalence of ECH attributed to PPE usage.

The best primary nutrition for babies is breast milk. Exclusive Breastfeeding is given since the baby is born for six months. Breastfeeding proofed to reduce infant mortality and morbidity. The rate of exclusive breastfeeding in Indonesia is still low at around 37.3%. The cause of the low number of breastfeeding is the lack of information obtained by the mother, affecting the mother's knowledge and belief. Breastfeeding mothers need the correct information. This information can be obtained from lactation counseling provided by health workers. This study aims to analyze the effect of counseling on knowledge, mothers' self-confidence, and breastfeeding ability in postpartum mothers. This research was conducted in July–September 2021 in the working area of the Sukaluyu Public Health Center, Cianjur regency. This research method uses a quasi-experimental design with a post-test only with a control group design—the sample in this study was 60 respondents, primigravida mothers aged 37 weeks to 1 month postpartum. The analysis used is the t-test and the Mann-Whitney test. This study uses three instruments: knowledge, self-confidence in the form of a Breastfeeding Self-Efficacy Scale Form (BSESF) questionnaire, and a breastfeeding ability observation sheet. The study results on mothers' knowledge in the intervention group were higher, namely 26, and there was a significant difference between the knowledge of the two groups (p=0.03). There are differences in the beliefs of breastfeeding mothers after being given counseling (p=0.001). There is no difference in the mothers' ability of the two groups after counseling (p=1.000). In conclusion, lactation counseling using video media increases the knowledge and confidence of breastfeeding mothers compared to those given standard care.

Blood that contains less iron can cause anemia. This nutritional case is the most common in almost all countries, including Indonesia. Female adolescents are more at risk of anemia due to stress, eating late, and losing large amounts of iron during menstruation. One part of the moringa plant (Moringa oleifera), namely the leaves, is believed to increase hemoglobin levels. The method of attracting adolescents to moringa leaf is by processing the moringa leaf becomes a snack called moringa leaf cilok. This research aims to determine the hemoglobin level of adolescent girls who experience anemia before and after being given moringa leaves cilok. This is experimental research with one group pre-post test design from October to November 2021 in Mataram. The subjects in this research are female adolescents with anemia who met the sample criteria. The sample used is n1=n2=32 respondents. The treatment group received moringa leaf cilok and was controlled tablets by giving iron tablets. The data collected was processed by a nonparametric test. The results show an effect of giving moringa leaf cilok on the hemoglobin levels of adolescent girls (p>0.05). The content of iron and vitamin C in moringa leaves cilok has increased hemoglobin levels. This research concludes that moringa leaf cilok can increase hemoglobin levels in female adolescents. Therefore, consuming moringa leaves cilok regularly can be used to treat anemia.

Exclusive breastfeeding can reduce infant mortality in Indonesia. Lack of breastfeeding is one of the causes of the low achievement of exclusive breastfeeding. Sauropus androgynus (L.) Merr (katuk) leaves are believed to increase milk production. Most people process katuk leaves to make vegetable soup, while improper processing methods can reduce the beneficial effects. This study aimed to analyze the effect of katuk leaf soup consumption on breast milk production. The subjects in the study were postpartum mothers and their babies from October to November 2021 at the PONED Health Center in West Lombok regency who met the sample criteria. This research is a randomized controlled trial. The sample used is 32 respondents. Katuk clear soup was given to the intervention group and Asifit to the control group. The data collected was processed by a nonparametric test. The analysis showed no difference in katuk clear soup and Asifit on breast milk production (p=0.105). Therefore, breast milk production increased due to katuk clear soup and Asifit made from katuk leaves. This research concludes that katuk leaves are proven to increase breast milk production. Therefore, katuk leaf vegetables can be used as an effort to increase breast milk.

The placenta accreta spectrum (PAS) is an abnormal placenta condition with a high level of morbidity and mortality in both the mother and fetus. The PAS has a multifactorial etiology, one of which is a chronic inflammation of the basal plate (CIBP) and the decidual existences (DE). The study aims to analyze the association between CIBP and DE with PAS. It was an analytical observational with a cross-sectional study design on 50 placentae (25 PAS paraffin block, 25 standard placenta samples) from Dr. Hasan Sadikin General Hospital and other health centers that meet the inclusion and exclusion criteria. The data are taken from PAS patients from January 2015–December 2020. All samples will be stained with hematoxylin-eosin (HE), then undergo histopathological examination. The result of the studies analyzed statistically using Fisher's exact. CIBP in PAS was found in 21/25 cases, while in the normal placenta was found in 16/21 patients. The DE is positive in 15/25 cases of PAS, whereas the normal placenta was found in all cases. The association between CIBP and PAS is insignificant statistically (p=0.19), while the DE showed a significant relationship with PAS (p=0.00). The presence of the decidua is related to the regulation of trophoblastic invasion into the myometrium in PAS cases. CIBP can occur due to the reaction of decidua tissue to trophoblastic invasion or an infectious agent. The pathogenesis of PAS needs further understanding so that the appropriate therapy can be found for its prevention and management.

The increasing occurrence of wastewaters associated with industrial development has begotten a permanent search for new and more efficient techniques for the removal of hazardous substances such as heavy metals and dyes. The use of natural and available resources to develop improved and sustainable commodities for this purpose remains crucial and is among promising emerging green technologies for water treatment. It offers the gradual shifting of hazardous industrial chemicals precursors to the abundant non-metallic mineral resources that receive an added value. This work investigated the uptake capacity by the adsorption process of methylene blue (MB) and azocarmine G (AG) onto nano-silica synthesized from kaolinite clay. The effects of contact time (0-30 min), the adsorbent dosage (5-100 mg), the initial pH of the solution (1-11 for MB and 1-7 for AG), and the initial dye concentration (5-50 mg/L) were studied. The selected conditions to carry out kinetic and isotherm adsorption experiments were: 15 mins, 20 mg, 11 for MB, 1.01 for AG, and 50 mg/L. Four adsorption isotherms and three kinetic models were used to model the adsorption data thanks to linear and non-linear regression methods. From the obtained results, the Freundlich isotherm model fitted well the adsorption phenomenon while the pseudo-second-order kinetic model described well the adsorption mechanism. Furthermore, the free energy of adsorption was similar for the two absorbents, 0.71 kJ, pointing physisorption as the dominant adsorption mechanism. The optimum MB and AG uptake were respectively 13.8 and 36.1 mg/g. Conclusively, the nano-silica represents a potentially viable and powerful adsorbent whose use could lead to a plausible improvement in environmental preservation.
Verdadeiros e falsos profetas
Authors: Garmus Ludovico
Published: August 2022

Ao lermos a Sagrada Escritura deparamos com certas figuras singulares na história de Israel e particularmente importantes no período da monarquia. São homens que pretendem falar em nome de Deus tanto aos reis, como às autoridades e ao povo em geral. Com a maior naturalidade insistem em dizer “o Senhor me enviou”, e autentificam sua mensagem com a fórmula: “Assim diz o Senhor Deus”. São, enfim, homens que “se arrogam o privilégio de terem escutado aquele que ninguém pode ouvir, de terem visto aquele que ninguém pode ver e do qual agora se apresentam como embaixadores”. Se tais pessoas não fossem os profetas de Israel, estaríamos inclinados a dizer que eles não passam de simples charlatães e mistificadores...
A SS. Trindade e a Existência Humana
Authors: Berg Adriano van den
Published: August 2022

Os manuais de teologia começavam, geralmente, por um tratado sobre Deus, “De Deo Uno”, para colocar, logo depois, um sobre a SS. Trindade, “De Deo Trino”. Todos os outros tratados seguiam estes dois primeiros. Cumpre observar, desde já, que a Trindade de Deus pouco influía nos tratados seguintes. Deus era visto como fonte viva de absolutamente tudo, de toda a realidade, e por isso era lógico primeiro estudar esta fonte, para depois compreender melhor tudo o que brotou dela...

Purpose: The article examines the role of digital and, in particular, social media in business-to-business marketing in the international software industry. The authors responded to calls for empirical research on how these media impact buyer-vendor relationships and the conjunction of the marketing and sales processes, particularly the distribution of complex software solutions. This paper develops a digital framework and discusses the managerial consequences. Design/methodology/approach: The model arises by merging themes derived from literature, experts, and job descriptions. Mixed Methods included conducting semi-structured interviews across marketing, business development, and sales executives from buyers, vendors, and third parties of various industries, supplemented by a survey of 530+ executives. Findings: Multinational companies secure competitive advantage through agile business processes to improve buyer-vendor relationships in the digital era. Digital media enable vendors to interact continuously with buyers, gather intelligence, and foster mutually beneficial, trustworthy, long-term relationships. The objective is to prompt transactions and secure revenue streams. Research limitations/implications: The outcomes of this research center on North America, Western Europe (including the UK), and DACH (Germany-Austria-Switzerland), affecting the generalizability. Originality/value: The research is novel and bridges several gaps concerning industrial relationships in digitalization: it merges buyer, vendor, and third-party’s perspectives on an international scale. It provides deeper insights into existing and new relationships by identifying relevant digital/social media platforms, the underlying usage motivation, and fundamental B2B processes. Finally, it equips practitioners with metrics to improve performance.
