Review of Crop Yield Prediction using Machine Learning Techniques
Authors: Narayan Kale Jaydeep
Published: July 2021

Machine learning (ML) could be a helpful decision-making tool for predicting crop yields, in addition as for deciding what crops to plant and what to try throughout the crop's growth season. To help agricultural yield prediction studies, variety of machine learning techniques are used. I performed a literature review (LR) to extract and synthesize the algorithms and options employed in crop production prediction analysis. Temperature, rainfall, and soil types are most common measure used in the prediction as per my knowledge, whereas Artificial Neural Networks is the foremost normally used methodology in these models.
Kisan Credit Card System: A Blessing to Small Farmers in India
Authors: Kurup Indu R
Published: July 2021

Agriculture is the spine of the Indian economy, with approximately 70% of the population of the country continuing to depend on it either directly or indirectly for their living. One of the major challenges confronting Indian banks has been the development of an all-encompassing system for timely and sufficient agricultural-rural credit disbursement. Agriculturalists extensively rely on non-institutional or unorganized sources of credit as a result of regular needs, insufficient availability of institutional credit, unnecessary delays, incommodious procedures, red-tapism, and inappropriate practices adopted by the lending agencies. Realizing the dominant role of the agriculture sector, rural credit requirements, and for reducing the dependence of farmers on unorganized sources of credit, the Kisan Credit Card (KCC) scheme was started by the Government of India in consultation with the NABARD and RBI in 1998 as a path-breaking credit distribution mechanism to provide adequate, timely, cost-effective and hassle-free credit support to farmers. In this conceptual paper, an attempt has been made to briefly explore the implications of the Kisan Credit Card system among small farmers in India.

HCI: Use in Cyber Security
Authors: Kulshreshtha Neelabh
Published: July 2021

This paper deals with the uses of HCI (Human-Computer Interaction) with Cyber Security and Information Security. Even though there have been efforts to strengthen the infrastructure of the security systems, there are many endemic problems which still exist and are a major source of vulnerabilities. The paper also aims to bridge the gap between the end-user and the technology of HCI. There have been many widespread security problems from the perspective of the security community, many of which arise due to the bad interaction between humans and systems. Developing on the Human-Computer Interaction is an important part of the security system architecture because even the most secure systems exist to serve human users and carry out human-oriented processes, and are designed and built by humans. HCI is concerned with the user interfaces and how they can be improved because most users' perceptions are based on their experience with these interfaces. There has been immense research on this field and many advances have been made in this arena of HCI. Speaking of Information Security on the other hand has been a major concern for the present world scenario where everything is done in the digital world.

This paper looks at the Acehnese women's movement in helping to respect women's work in the grassroots community. This effort was carried out to give recognition and appreciation for women who have dedicated themselves to upholding women's human rights in Aceh, because there are still many people who do not yet know the humanitarian work they have done. The women who were nominated were those who worked since the time of the conflict until now. This voluntary work they do without financial support on a regular basis from the government, although some of them are listed as volunteers in their respective city P2TP2A. The types of cases they handle vary, from domestic violence cases to women's empowerment and society. This research was conducted in the Banda Aceh, Bener Meriah and Central Aceh regions. The research method for this study was in-depth interviews of winners, nominees and implementers of activities shaded by the Ureung Inong Aceh Shura Hall. The results of this study indicate that there are ups and downs in the implementation of this activity. Some of the obstacles that hindered him were the unavailability of funds, weak government commitment and lack of coordination of women's institutions in Aceh in the success of this activity.Keywords: Aceh Women Award, Aceh Women's Movement, Empowerment

Authors: Zamora-Araya José Andrey , Ramírez Jiménez Jeremías , Delgado-Navarro Fabiola
Published: July 2021

El uso de las TIC en contextos escolares es un valioso recurso para los procesos de enseñanza-aprendizaje en muchas disciplinas y la Matemática no es la excepción. El objetivo del documento es contrastar la hipótesis de que el uso de herramientas tecnológicas en las clases del curso de MAT003 Cálculo II mejora el rendimiento académico de los estudiantes. Para ello se diseñó un cuasiexperimento con tres niveles de tratamientos cuya variable dependiente esta representada por la nota del segundo examen parcial en la asignatura. El primer grupo experimental usó videos y software matemáticos como apoyo a las clases y el segundo grupo únicamente videos, el tercer tratamiento estuvo constituido por el grupo control. Como variables de control se tomaron las notas del curso de cálculo I y del primer parcial de la asignatura de cálculo II, las cuales no mostraron tener diferencias significativas entre los diferentes grupos. Se aplicó un análisis de varianza con corrección de Welch y se calcularon los tamaños de efecto entre los tratamientos. Aunque el resultado del análisis de varianza no resultó ser significativo (0=0.053), los tamaños de efecto y niveles de aprobación por tratamiento muestran evidencia en favor del uso de TIC como medio para mejorar el rendimiento académico en el curso de MAT003 Cálculo II.

CON: Fomepizole should be used more liberally in paracetamol overdose
Authors: Dear James
Published: July 2021

Fomepizole is a promising new treatment for preventing liver injury
following paracetamol (acetaminophen) overdose. However, we need robust
clinical trials to be performed to demonstrate its effect on clinical
outcomes that are important to our patients and important to healthcare
providers. Until such trials are performed, the toxicology community
should learn the lessons from the COVID pandemic – potential novel
therapeutic options may be theoretically appealing, but their
effectiveness needs to be assessed in robust clinical trials before they
are used in clinical practice.
How do genetic relatedness and spatial proximity shape African swine fever infections in wild boar?
Authors: Podgórski Tomasz , Pepin Kim , Radko Anna , Podbielska Angelika , Łyjak Magdalena , Wozniakowski Grzegorz
Published: July 2021

The importance of social and spatial structuring of wildlife populations
for disease spread, though widely recognized, is still poorly understood
in many host-pathogen systems. In particular, system specific kin
relationships among hosts can create contact heterogeneities and
differential disease transmission rates. Here, we investigate how
distance-dependent infection risk is influenced by genetic relatedness
in a novel wild boar ( Sus scrofa) - African swine fever (ASF)
system. We hypothesized that the infection risk would correlate
positively with proximity and relatedness to ASF-infected individuals
but expected those relationships to weaken with distance between
individuals due to decay in contact rates and genetic similarity. ASF
infection risk was shaped by the number of infected animals throughout
the zone of potential contact (0-10 km) but not beyond it. This effect
was the strongest at close distances (0-2 km) and weakened further on
(2-10 km), consistent with decreasing probability of contact. Overall,
there was a positive association between genetic relatedness to
infectees and infection risk within the contact zone but this effect
varied in space. In the high-contact zone (0-2 km), infection risk was
not influenced by relatedness when controlled for the number of
ASF-positive animals. However, infections were more frequent among close
relatives indicating that familial relationships could have played a
role in ASF transmission. In the medium-contact zone (2-5 km), infection
risk and frequency of paired infections were associated with
relatedness. Relatedness did not predict infection risk in low- and
no-contact zones (5-10 and >10 km, respectively). Together,
our results indicate that the number of nearby infected individuals
overrides the effect of relatedness in shaping ASF transmission rates
which nevertheless can be higher among close relatives. Highly localized
transmission highlights the possibility to control the disease if
containment measures are employed quickly and efficiently.
Multiple nodal solutions for the Schr\”odinger-Poisson system with an asymptotically cubic term
Authors: Guo Hui , Tang Ronghua , Wang Tao
Published: July 2021

This paper deals with the following
Schr\“odinger-Poisson system
\begin{equation}\left\{\begin{aligned}
&-\Delta u+u+ \lambda\phi
u=f(u)\quad\mbox{in
}\mathbb{R}^3,\\
&-\Delta
\phi=u^{2}\quad\mbox{in
}\mathbb{R}^3,
\end{aligned}\right.\end{equation}
where $\lambda>0$ and $f(u)$ is a
nonlinear term asymptotically cubic at the infinity. Taking advantage of
the Miranda theorem and deformation lemma, we combine some new analytic
techniques to prove that for each positive integer $k,$ system
\eqref{zhaiyaofc} admits a radial nodal solution
$U_k^{\lambda}$, which has exactly $k+1$ nodal
domains and the corresponding energy is strictly increasing in $k$.
Moreover, for any sequence
$\{\lambda_n\}\to
0_+$ as $n\to\infty,$ up to a
subsequence, $U_k^{\lambda_n}$ converges to some
$U_k^0\in
H_r^1(\mathbb{R}^3)$, which is a radial nodal
solution with exactly $k+1$ nodal domains of
\eqref{zhaiyaofc} for $\lambda=0 $.
These results give an affirmative answer to the open problem proposed in
[Kim S, Seok J. Commun. Contemp. Math., 2012] for the
Schr\”odinger-Poisson system with an asymptotically
cubic term.
A comprehensive study of indole catalytic hydrodenitrogenation under hydrothermal conditions
Authors: Liu Xu , Guo Yang , He Haoran , Kong Lingzhao
Published: July 2021

This article focuses on the catalytic hydrodenitrogenation (HDN)
mechanism of indole under hydrothermal conditions. Both gaseous hydrogen
and liquid hydrogen donor formic acid (FA) can improve indole conversion
and total yield of denitrogenated products. Ru/C showed the highest
activity among the catalysts for indole conversion in all temperature
conditions with the existence of H2 and 91.17 % indole was converted at
400 °C and 60 min. Based on reaction kinetic experiments, a kinetic
model was developed to describe the hydrothermal HDN reaction of indole
over the home-made Ni80Ru20/γ-Al2O3 catalyst, which clearly captured all
data trends and fitted the temporal variation of all major liquid
products. High activation energy for formation of O-containing substance
o-cresol from both mathematical fitting and density functional theory
(DFT) calculation indicated a rare occurrence of reaction between
pyrrole ring-opening product methyl aniline and H2O, consistent with
experimental observation that only a trace of o-cresol was detected.
Failure of non-vitamin K antagonist oral anticoagulants in preventing stroke in elderly patient: a case report of multiple strokes on standard of care treatment for atrial fibrillation
Authors: Ebai Frank Bernard , Mohiuddin Azam
Published: July 2021

Atrial fibrillation (AF) is the most common type of treated heart arrhythmia. Generally, the treatment goals for atrial fibrillation are to reset the rhythm or control the rate and prevent the development and subsequent embolization of atrial thrombi. These thromboembolic events can occur with any kind of atrial fibrillation that is paroxysmal, persistent or permanent. In patients who are candidate for anticoagulation therapy, major practice guideline provides vitamin K antagonist (VKA) oral anticoagulant and non-VKA oral anticoagulants as treatment options. The risk of AF increases with age and despite treatment on standard of care anticoagulation therapy, recrudescent cardioembolic events may still arise especially in the elderly as we will see in this case.

Published: July 2021

This study contributes data on haematological and biochemical parameters of
African catfish, Clarias gariepinus. It employed a 3 ? 2 factorial design
with three ponds of different water depth (0.5, 1 and 1.5 m) and two types
of feed (floating and sinking). Twelve earthen ponds (1 m x 2 m) were
stocked with 16 fingerlings catfish each (mean weight ~100g) and their blood
parameters were monitored over 12 weeks. Differences in hematological
parameters related to water depth were mostly significant, and better
results were recorded in fish reared in shallower water ponds. Feed type
showed improved hematological parameters with using of sinking diet. Most
biochemical parameters showed significant differences in pond waters depth
and feed type with better results coincided with rearing fish in shallower
water depth and with sinking feed. Conclusively, culturing Catfish in
shallow ponds (0.5 m) and use of sinking feed improve physiological response
and health condition.

Published: July 2021

The growing global demand for renewable energy sources has pushed renewable, green energy sources to the forefront, among which the production of hydrogen gas from water occupies a significant place. To realize this goal, researchers across the globe are developing various systems that could swiftly catalyze the hydrogen evolution reaction (HER) in the highest possible yield. In the present work, the electrocatalytic HER performances of pyridoxal semicarbazone- and thiosemicarbazone-based Cu(II) complexes, i.e., ([Cu(PLSC)Cl2] and [Cu(PLTSC-H)H2O]Br?H2O) are reported. It has been unambiguously demonstrated that the complexes exhibit enviable level of HER catalytic activity. The catalytic activity of the complexes was not only the function of central metal but it was also controlled by the nature of the coordinating ligand.
An alternative treatment approach for patients with resistant otitis media with effusion and dysfunctional Eustachian tube:
Authors: Kılıç Nihat , Yörük Özgür , Kılıç Songül Cömert
Published: July 2021

Objectives

To determine whether dysfunctional Eustachian tubes of children with resistant otitis media with effusion (OME), ventilation tube placement indication, and maxillary constriction will recover after rapid maxillary expansion (RME).

Materials and Methods

The RME group consisted of 15 children (mean age: 10.07 years) with maxillary constriction, Eustachian tube dysfunction (ETD), and resistant OME. The control group consisted of 11 healthy children (mean age: 8.34 years) with no orthodontic and/or rhinologic problems. Recovery of Eustachian tube dysfunction was evaluated by Williams' test at three timepoints: before RME/at baseline (T0); after RME (T1); and after an observation period of 10 months (T2). The control group was matched to all these periods, except T1.

Results

In the control group, functioning Eustachian tubes were observed in all ears at baseline (T0), and tubes showed no worsening and no change during the observation period (T2) (P > .05). In the RME group, functioning Eustachian tubes were observed in eight of 30 ears and ETD was observed in the remaining 22 ears at baseline (T0). The RME group showed significant improvements in tube functions after RME and the observation period (P < .05). Fifteen of 22 dysfunctional ears recovered (68.2%) and started to exhibit normal Eustachian tube function after RME (T1) and the observation period (T2).

Conclusions

The findings suggest that ears having poorly functioning Eustachian tubes are restored and recovered after RME in most of children with maxillary constriction and resistant OME. Thus, RME should be preferred as a first therapy alternative for children with maxillary constriction and serous otitis media.

Published: July 2021

No longitudinal data link intraglomerular hemodynamic dysfunction with end-stage kidney disease (ESKD) in people with type 2 diabetes (T2D). Afferent (RA) and efferent (RE) arteriolar resistance and intraglomerular pressure (PGLO) are not directly measurable in humans but are estimable from glomerular filtration rate (GFR), renal plasma flow (RPF), blood pressure, hematocrit, and plasma oncotic pressure. We examined the association of the RA-to-RE ratio and PGLO with ESKD incidence in 237 Pima Indian individuals with T2D who underwent serial measures of GFR (iothalamate) and RPF (p-aminohippurate). Their association with kidney structural lesions was also examined in a subset of 111 participants. Of the 237 participants (mean age 42 years, diabetes duration 11 years, and GFR 153 mL/min and median urine albumin–to–creatinine ratio 36 mg/g), 69 progressed to ESKD during a median follow-up of 17.5 years. In latent class analysis, distinct trajectories characterized by increasing RA-to-RE ratio (HR 4.60, 95% CI 2.55–8.31) or elevated PGLO followed by a rapid decline (HR 2.96, 95% CI 1.45–6.02) strongly predicted incident ESKD. PGLO (R2 = 21%, P < 0.0001) and RA-to-RE ratio (R2 = 15%, P < 0.0001) also correlated with mesangial fractional volume, a structural predictor of DKD progression. In conclusion, intraglomerular hemodynamic parameters associated strongly with incident ESKD and correlated with structural lesions of DKD.

OBJECTIVE

The metabolic phenotype of youth-onset type 2 diabetes (T2D) differs from that of adult-onset T2D, but little is known about genetic contributions. We aimed to evaluate the association between a T2D genetic risk score (GRS) and traits related to glucose-insulin homeostasis among healthy youth.

RESEARCH DESIGN AND METHODS

We used data from 356 youth (mean age 16.7 years; 50% female) in the Exploring Perinatal Outcomes Among Children (EPOCH) cohort to calculate a standardized weighted GRS based on 271 single nucleotide polymorphisms associated with T2D in adults. We used linear regression to assess associations of the GRS with log-transformed fasting glucose, 2-h glucose, HOMA of insulin resistance (HOMA-IR), oral disposition index, and insulinogenic index adjusted for age, sex, BMI z score, in utero exposure to maternal diabetes, and genetic principal components. We also evaluated effect modification by BMI z score, in utero exposure to maternal diabetes, and ethnicity.

RESULTS

Higher weighted GRS was associated with lower oral disposition index (β = −0.11; 95% CI −0.19, −0.02) and insulinogenic index (β = −0.08; 95% CI −0.17, −0.001), but not with fasting glucose (β = 0.01; 95% CI −0.01, 0.02), 2-h glucose (β = 0.03; 95% CI −0.0004, 0.06), or HOMA-IR (β = 0.02; 95% CI −0.04, 0.07). BMI z score and in utero exposure to maternal diabetes increased the effect of the GRS on glucose levels.

CONCLUSIONS

Our results suggest that T2D genetic risk factors established in adults are relevant to glucose-insulin homeostasis in youth and that maintaining a healthy weight may be particularly important for youth with high genetic risk of T2D.

O corpo humano e o dom divino: uma análise das experiências de transe nas igrejas pentecostais
Authors: Laranjeira Gisele Cristina
Published: July 2021

Este artigo visa observar e analisar as experiências de transe nas igrejas pentecostais em torno de sua compreensão mítica, embasada pelo texto bíblico do Dia de Pentecoste e da concessão dos dons do Espírito Santo aos fiéis. Primeiro, o artigo trabalha o conceito de universo simbólico, elaborado por Berger e Luckmann (2014), como plano de fundo para a interpretação das experiências de transe como alicerce de um modelo de compreensão da realidade. Junto a outros autores, traz junto à análise a necessidade de uma configuração social, cultural e histórica para elaborar a experiência religiosa corporal. No caso do fiel pentecostal brasileiro, a apresentação dos dons se alinha à apresentação de um corpo que assimila sua identidade humana e herdeira da Vontade e dos Dons Divinos – assimilação que se aplica de forma contundente no seu dia a dia.

Authors: Ribeiro Antonio Carlos
Published: July 2021

O presente trabalho tem como objetivo analisar a frequência de denúncias de violação ao direito à liberdade religiosa no “Brasil” entre 2011-2018, com destaque para as religiões afro-brasileiras. O estudo foi motivado pela afirmação de um suposto contexto de “cristofobia” em recente discurso de Bolsonaro na ONU e pautou-se por um caráter exploratório, descritivo e de abordagem quantitativa, a partir dos dados disponibilizados pelo Serviço Disque 100 – Direitos Humanos, do Ministério da Mulher, da Família e dos Direitos Humanos (MMFDH), em formas de planilhas com o número de registros de casos de intolerância religiosa nos diversos Estados do Brasil no período de 2011 a 2018. Foi identificado o universo de 2.862 casos. A região geográfica identificada com maior índice de denúncias foi o Sudeste 33% de casos, concentrando o maior número de registros no estado de São Paulo, com 14% de casos. O segmento religioso com mais ocorrência de casos de intolerância se constituiu de 23% proveniente das religiões afro-brasileiras. O perfil das vítimas, considerado por módulo, foi de 25% constituído de pessoas de raça/cor branca, 42% composto de pessoas do sexo feminino, 34% possuíam entre 18 a 40 anos. Foi verificado aumento na frequência de registro de denúncias de intolerância religiosa no recorte geográfico e histórico submetidos à análise, sobretudo aos adeptos afro-religiosos, sustentado elementos que indicam aversão às religiões afro-brasileiras.
O corpo feminino como intertexto moral do feminicídio
Authors: Gomes Carlos Magno
Published: July 2021

Este artigo apresenta uma proposta comparatista entre o corpo feminino assassinado e os códigos morais da sociedade patriarcal no conto “Dolly” (1995), de Lygia Fagundes Telles, e no romance Mulheres empilhadas, de Patrícia Melo (2019). Articulamos uma abordagem interdisciplinar para a confecção do corpo feminino suplicado como um intertexto moral hegemônico. Essa estratégia está relacionada ao questionamento do aniquilamento feminino. Metodologicamente, desenvolve-se a construção do conceito de corpo suplicado como intertexto moral a partir do debate proposto por Michel Foucault, Tiphaine Samoyault, Elódia Xavier e Lia Zanotta Machado. Nessas obras, o corpo da mulher está representado por meio de uma perversa normatização de gênero, respaldada pelo suplício da vítima e reforçada por meio de intertextos jornalísticos paralelamente enxertados ao texto ficcional.TRANSLATE with x EnglishArabicHebrewPolishBulgarianHindiPortugueseCatalanHmong DawRomanianChinese SimplifiedHungarianRussianChinese TraditionalIndonesianSlovakCzechItalianSlovenianDanishJapaneseSpanishDutchKlingonSwedishEnglishKoreanThaiEstonianLatvianTurkishFinnishLithuanianUkrainianFrenchMalayUrduGermanMalteseVietnameseGreekNorwegianWelshHaitian CreolePersian //  TRANSLATE with COPY THE URL BELOW Back EMBED THE SNIPPET BELOW IN YOUR SITE Enable collaborative features and customize widget: Bing Webmaster PortalBack//

THROE OF BEING STOLEN IN DORIS PILKINGTON’S CAPRICE - THE STOCKMAN’S DAUGHTER
Authors: Sharmila Colette , Betsy Dr. A. JosephineAlangara
Published: July 2021

The British controlled dominated and exploited the indigenous population in the process of colonizing Australia in the late Eighteenth Century. They appropriated the aborigines’ land, resources and wealth: they also left psychic scars of stealing their children from the indigenous families under the guise of civilization. Colonial Governments saw Aboriginals not as people who had been colonized but as heathens to be converted and institutionalized. The ‘Assimilation Policy’ as it was called advocated in all the states of Australia in order to remove the half caste aboriginal children. This paper will foreground on the psychic scars of the Stolen Generation writer Doris Pilkington’s novel Caprice - The Stockman’s Daughters. Further this paper will discuss and analyse the fear, persecution, angst desolation and the pain felt by the stolen children and their families in the novel Caprice - The Stockman’s Daughter.
