Published: April 2023

Abstract: The state should make investments in cutting-edge technologies like precision agriculture, which employs sensors to track crop health and soil conditions, to address this problem. When choosing the best time to sow, water, and harvest their crops, farmers can use this technology to their advantage. The state should also think about funding research and development to produce new crop kinds that are more resistant to environmental conditions like climate change. Agricultural characteristics and determinants offer important insights into the situation of agriculture right now. Decisions about crop yields, soil fertility, water consumption, and other crucial agricultural issues can be informed by these data. Moreover, technological advancements have made it possible tocreate new tools and technologies that might assist farmers in making more informed decisions on their operations. Farmers can benefit from modern technology in numerous ways, including increased agricultural yields, lower expenses, andmore efficiency. Furthermore, access to more effective marketing and distribution channels is another way that technology may assist farmers in boosting their income. The best crops for a given climate and area can be found using data analytic. To do this, historical data on agricultural yields, weather patterns, soil conditions, and other elements that may have an impact on crop development can be examined. Farmersmay choose the crops to grow and the best methods for managing them to increase yields by using data analytic.

Published: April 2023

Abstract: The vortex generators in this study are placed at angle of 30° in a rectangular channel. These vortices create the down wash flow towards the lower channel wall while the up wash flow is away from the wall which is found in the outside region of the vortices. Along the downstream direction, the secondary velocity vectors decreases while the distance between the vortex cores increases. Thinning of the thermal boundary layer thus occurs in between the two vortices. The variation of span wise averaged Nusselt number was calculated at different values of x at Reynolds number of 800, 1200. We considered parametric studies between channel without winglet and with winglet pair. It shows that the span wise averaged Nusselt number increase with the increment of Reynolds no. at particular x. it is observed the behaviour at these Reynolds no with blade angle 30°. The increment in the span wise averaged Nusselt no. can be observed from these numerical calculations. the effect of vortex generators in the spanwise averreged nusselt number. The comparison between the plots of spanwise avereged Nusselt number with and without vortex generators shows that there is a considerable increase in Nusselt number near the vortex generator region and this effect decreases as we move far from the vortex generator region in the stream wise direction.

Abstract: Millions of people in India have traditional skills and knowledge in the production and production of handicrafts. The Indian handicrafts industry is decentralized and highly labor- intensive. After textiles and agriculture, it offers the most employment opportunities. The industry has contributed significantly to the country's economy, but it has not yet received the recognition it deserves. Craftsman’s are exclusively reliant upon center individual for the selling of the items. This results in a one- dimensional strategy that fails to showcase the proud artisans' skills and reduces profits. Internet marketing has the potential to effectively address the issue facing artisans to our advantage.
Driver Drowsiness Detection System using Deep Learning

Published: April 2023

Abstract: These days, an ever-increasing number of professions require long time focus. Drivers should watch out for the street, so they can respond to abrupt occasions right away. Due to driving for a long time or intoxication, drivers might feel sleepy, which is the biggest distraction for them while driving. This distraction might cost the death of the driver and other passengers in the vehicle, and at the same time, it also causes the death of people in the other vehicles and pedestrians too. To prevent such accidents, we propose a system that helps to alert the driver if he/she feels drowsy. To accomplish this, we implement the solution using a computer-vision-based machine learning model. The driver’s face is detected by a face recognition algorithm continuously using a camera, and the face of the driver is captured. The face of the driver is given as input to a classification algorithm which is trained with a data set of images of drowsy and non-drowsy faces. The algorithm uses landmark detection to classify the face as drowsy or not drowsy. If the driver’s face is drowsy, a voice alert is generated by the system. This alert can make the driver aware that he/she is feeling drowsy, and the necessary actions can then be taken by the driver. This system can be used in any vehicle on the road to ensure the safety of the people who are traveling and prevent accidents that are caused due to the drowsiness of the driver

Research Paper on ROTUNDA
Authors: Kaushik Pranav , Kumar Akash
Published: April 2023

Abstract: This Paperwork focuses on the comparison of seismic analysis of Modern office building design. The performance of the building is analyzed in Zone II, Zone III, Zone IV, and Zone V. The study includes understanding the main consideration factor that leads the structure to perform poorly during the earthquake for humans. Provision of shear walls are installed is installed to enhance the lateral stiffness, ductility, minimum lateral displacements, and structure safety to enhance the lateral stiffness, ductility, minimum lateral displacements, and safety of the structure. Storey drift and lateral displacements are the critical issues in seismic design of buildings. Due to the Industrial revolution, availability of jobs and facilities, population from rural area is migrating towards cities. Because of this metro cities are very thickly populated. Availability of land goes on decreasing and land cost also increases. To overcome this problem the use of multistoried buildings is necessary. But such provisions increase self-weight and live load along with earthquake forces. With increase in height stress, strain, deformation and displacement in the structure, the cost of construction increases due to increased cross-sections of the elements. Multi-Storey buildings are designed to carry gravity loads, earthquake loads and their combinations. I.S. codes provide these loading combinations for which structure needs to be analyzed and designed. The analysis is aimed at finding the internal forces in component of structures and to find displacements developed in the structure leading to the development of strains. Structure must be safe from both strength viewpoint and serviceability as well. While vertical forces are most significant, the primary problem for most structures is force in the horizontal or lateral direction, which tends to subject buildings to large horizontal distortion. Therefore, most buildings are designed with lateral-force-resisting systems to resist the effects of earthquake forces. Bare frames are found to be more flexible and have large section requirement to with stand forces induced.

To Study and Investigate Wear Behavior of Zinc Plating on 316L SS by using Taguchi Optimization Method
Authors: Dadhe Milind Arun , Hambire U. V. , Ambekar S. D.
Published: April 2023

Abstract: Zinc Plating (Electroplating) is one of the most used coating method in the industries. Zinc plating is widely applied to almost all the metal parts manufactured in the industry. Industries faces the problem of metal part rusting and corroding after a specific time from installation of that part, which eventually leads to replacing the part or its maintenance either of this will cause the reduction in production or will cost for the metal part replacement. In this project work I have come with a solution for the problem of rusting and corrosion by using Taguchi Optimization, OVAT followed by L-9 Orthogonal Array and ANOVA. When the part is ready it must be zinc plated or electroplated at a specific thickness which we have studied in research work by testing the various thickness of 316L SS zinc plated specimens which give us a summary of what thickness will be the best to minimize the problem of rusting, so that once a metal part is installed in a industry it will not be frequently required to be maintained or replaced which will reduce the cost to industry for the maintenance and replacement and will not hinder the production line of a specific industry

Published: April 2023

Abstract: Combining various medical pictures will improve illness diagnosis accuracy and illustrate the complex link between them for medical study. Existing approaches take a long time and require a large number of data to train the models. In this model, we will use multi-stage fusion networks to extract sophisticated information from medical pictures such as Magnetic Resonance Imaging (MRI) and Computed Tomography (CT). In the suggested approach, we will extract the difficult and correlated information from each picture using the Dual Tree Complex Wavelet Transform (DTCWT), and then segment the fused image to obtain the segmented image. The proposed approach entails, the fusion of multimodal medical pictures may be accomplished using the Dual Tree Complex Wavelet Transform, which converts the original medical image to grayscale and decomposes it before extracting the wavelet coefficients using DTCWT. Following that, wavelet approximation is utilized to produce the fused coefficients. To obtain a final fused picture, the Inverse Dual Tree Complicated Wavelet Transform is performed. Additionally, segmentation is carried out in order to provide a segmented image for better visual representation. The quality of the final fused picture can be increased using the proposed strategy.

Definición y caracterización de regiones económicas en Chile
Authors: Rowland López Fernando
Published: April 2023

En Chile no hay un criterio específico a la hora de determinar los límites de cada una de las regiones políticas administrativas y tampoco información o un análisis detallado de las economías de estas regiones. Es por ello, que a través de un análisis clúster jerárquico utilizando el PIB Regionalizado por sector productivo determinamos conglomerados de regiones, a partir de los cuales obtuvimos regiones económicas, es decir, regiones que tienen similitudes en su estructura productiva y finalmente las caracterizamos a través de las técnicas de análisis con información limitada. Encontramos cuatro conglomerados de regiones y siete regiones económicas, siendo cada región económica diferente una de otra. A pesar de encontrar siete regiones económicas, no necesariamente significa que deben ser regiones político-administrativas porque para definir una región política administrativa se deben considerar aspectos más complejos que el económico.

An integrated framework based on triple bottom line accounting and stakeholders’ perspective to promote sustainable facility location and route allocation network decisions
Authors: Anvari Saeedeh , Macharis Cathy , Turkay Metin
Published: April 2023

Sustainable operations are becoming important for companies, after the United Nations 2030 agenda that emerges countries to move toward sustainable development. Taking care of the environment, society, local communities, and related stakeholders are components of sustainable development that are affected by companies’ operations. The facility location/demand allocation/route assignment decisions (hereinafter network) for a company is an operation that has varying economic, environmental, and social outcomes (three pillars) for the company and the related stakeholders. Having an integrated decision support framework that considers three pillars simultaneously and incorporates stakeholders’ preferences seems necessary in the network design to reach a sustainable network and promote sustainable development. This framework is missing in the literature. We present a framework that integrates multi-objective mathematical modeling (MOMM) (Anvari & Turkay, 2017) and multi-actor multi-criteria analysis (MAMCA) (Macharis et al., 2012). MOMM generates a pool of feasible sustainable solutions based on three pillars. Then MAMCA analyzes the feasible solutions for each stakeholder. The company (investor) uses these analyses to decide on the best sustainable solution, which satisfies the three pillars and reduces future risks of conflicts among stakeholders. We apply our approach to an original case to establish the network for a juice company in Turkey using real data.
Neural network-based diffuse fluorescence tomography reconstruction algorithms to improve image quality
Authors: Pan Yingxue , zhang limin , Zhuanxia * , Sun Wenjing , Xing Lingxiu , Zhang Yanqi , Jia Mengyu , Liu Dongyuan , Gao Feng
Published: April 2023

Diffuse fluorescence tomography (DFT) is a promising noninvasive imaging
modality. To date, traditional physics-based approaches cannot
substantially improve the imaging quality due to inherent light
scattering property and severe ill-poseness of inverse problem.
Therefore, three neural networks, namely, back-propagation neural
network (BPNN), convolutional neural network (CNN) and U-net trained in
an end-to-end fashion are explored to improve imaging quality. To
evaluate their performance, a series of simulation, phantom and in vivo
experiments are conducted for single and double-target reconstructions,
and the results are compared with the traditional algebraic
reconstruction technique (ART). The numerical results demonstrate that
the neural network-based algorithms significantly enhance the image
quality in terms of target shape, size, location, as well as noise
robustness. The subsequent phantom and in vivo experimental results
verify the effectiveness of the well-trained networks to estimate
experimental data. Comparatively, BPNN is competitive in computational
efficiency and generalization capacity.
How much does VPD drive tree water stress and forest disturbances?

Published: April 2023

Vapor Pressure Deficit (VPD, atmospheric drought) and soil water
potential (Ψsoil, soil drought) have both been reported to affect
terrestrial plant water stress, plant functions (growth, stomatal
conductance, transpiration) and vulnerability to ecosystem disturbances
(mortality or vulnerability to wildfires). Which of atmospheric drought
or soil drought has the greatest influence on these responses is yet an
unresolved question. Using a state-of-the-art soil-plant-atmosphere
hydraulic model, we conducted an in-silico experiment where VPD and
Ψsoil were manipulated one at a time to quantify the relative importance
of atmospheric vs soil drought on most critical plant functions. The
model simulates the combined effects of soil drought and atmospheric
drought on plant water potential (ΨPlant), a physiologically meaningful
metric of plant water status driving plant turgor, stomatal conductance,
hydraulic conductance or water content, and thus mortality and fire
risks. Contrary to expectations, we showed that VPD had a weaker effect
than Ψsoil on tree water stress and forest disturbances risk (i.e leaf
moisture content). While physiological responses associated with low
water stress such as stomatal closure or turgor loss could be driven by
both VPD or soil drought, consequences of extreme water stress such as
hydraulic failure, leaf desiccation and vulnerability to wildfires were
almost exclusively driven by low Ψsoil. Our results therefore suggest
that most plant functions are affected by VPD through its cumulative
effect on Ψsoil via increased plant transpiration, rather than through a
direct instantaneous effect on plant water potential. We argue that
plant hydraulics provide a strong foundation for predicting tree and
terrestrial ecosystem responses to climate changes and propose a list of
explanations and testable hypotheses to reconcile plant hydraulic theory
and observations of soil and atmospheric drought effects on plant
functions.
Phytochemical diversity enhances community resistance to herbivory in a tropical rainforest

Published: April 2023

Metabolomics provides an unprecedented window on diverse plant secondary
metabolites that represent a potentially critical niche dimension in
tropical forests underlying co-existence. Here, we used untargeted
metabolomics to evaluate the chemical composition of 358 tree species
and its relationship to phylogeny and variation in light environment,
soil nutrients, and insect-herbivore leaf damage in a tropical rain
forest plot. We found that tree species that co-occur locally are less
chemically similar than random, and that local chemical dispersion and
metabolite diversity reduce herbivory, especially that of specialist
insect herbivores. Our results suggest that plant secondary metabolites
have the potential to mediate plant-herbivore interactions in a manner
consistent with diversity maintenance at the community scale.

The Use of Homework in Emotion-Focused Therapy for Depression
Authors: Warwar Serine
Published: April 2023

EFT is an empirically supported treatment of depression for individuals,
and is also considered to be an integrative, transdiagnostic therapy
approach focusing on emotions that are the cause of a client’s emotional
pain and suffering. The target of treatment is to facilitate emotional
processing to change unhealthy emotion schemes that underlie current
symptoms of depression. The therapist is highly attuned to the client’s
moment-by-moment process to promote in-session work on emotion,
alongside experiential teaching. In-session work is consolidated and
expanded by between-session homework, which is viewed as a natural
extension of the in-session work. EFT views the therapist as an emotion
coach who offers interventions within a client’s developmental and
experiential learning capabilities to move them to their end goals. A
case example is discussed to illustrate how homework is used effectively
in treating a depressed client in relation to treatment principles over
the course of treatment.

subtropical Queensland, Australia. Our main objective was to quantify
the impact of groundwater level changes and flow regulation on
spatio‑temporal patterns in hydrology and water quality in the two
streams. In intermittently flowing Lockyer Creek, flow was highly
dependent on groundwater levels and occurred when the aquifer was
recharged to elevations exceeding the upper 90‑percentile value. With
9.4% of the catchment area in irrigated horticulture, flow in Lockyer
Creek was also likely to be reduced by drawdown of the aquifer for
irrigation, with no flow for 30% to 81% of days over the observation
period for stations in Lockyer Creek. In contrast, flow in the
mid‑Brisbane River was continuous, regulated by discharge from a large
upstream dam. Nutrient and suspended sediment concentrations in Lockyer
Creek were generally higher than in the mid‑Brisbane River, likely
associated with runoff from agricultural areas adjacent to the stream,
while the upstream dam likely reduced the concentration and variability
of nutrients and suspended sediment in the mid‑Brisbane River. During
periods of baseflow in the mid‑Brisbane River, longitudinal changes in
nutrient and suspended sediment concentrations occurred, notably a
significant decrease in total and dissolved inorganic nitrogen
downstream (p < 0.05), indicating a possible effect of
in-stream algal uptake and denitrification. This study highlights the
impact of human modifications on stream hydrology and water quality in
the face of climate change. The findings can inform decision-making on
groundwater irrigation or dam release control for water security.

In the vein of other areas of human knowledge, the theories and models developed for management and leadership are being settled by some scientific paradigms. In this respect, two major paradigms, namely, the Newtonian and quantum, have extensively influenced all organizational theories and models. Implementing such models accordingly calls for new management styles, here termed quantum management (QM). For this purpose, 16 experts of educational management, selected by purposive sampling, were interviewed until theoretical saturation was reached. The study findings demonstrated that the causal conditions with a weak coefficient of determination (R², 28%) were the moderate predictors of QM in educational organizations. As well, the underlying and intervening conditions along with QM with a medium R2 (51%) could strongly predict the strategies/enablers, and then the strategies/enablers with a medium R2 (55%) were the strong predictors of the QM consequences.
Subendothelial Matrix Stiffening by Lysyl Oxidase Enhances RAGE-Mediated Retinal Endothelial Activation in Diabetes

Published: April 2023

Endothelial cell (EC) activation is a crucial determinant of retinal vascular inflammation associated with diabetic retinopathy (DR), a major microvascular complication of diabetes. We previously showed that, similar to abnormal biochemical factors, aberrant mechanical cues in the form of lysyl oxidase (LOX)-dependent subendothelial matrix stiffening also contribute significantly to retinal EC activation in diabetes. Yet, how LOX is itself regulated and precisely how it mechanically controls retinal EC activation in diabetes is poorly understood. Here, we show that high-glucose–induced LOX upregulation in human retinal ECs (HRECs) is mediated by proinflammatory receptor for advanced glycation end products (RAGE). HRECs treated with methylglyoxal (MGO), an active precursor to the advanced glycation end product (AGE) MG-H1, exhibited LOX upregulation that was blocked by a RAGE inhibitor, thus confirming the ability of RAGE to promote LOX expression. Crucially, as a downstream effector of RAGE, LOX was found to mediate both the proinflammatory and matrix remodeling effects of AGE/RAGE, primarily through its ability to crosslink or stiffen matrix. Finally, using decellularized HREC-derived matrices and a mouse model of diabetes, we demonstrate that LOX-dependent matrix stiffening feeds back to enhance RAGE, thereby achieving its autoregulation and proinflammatory effects. Collectively, these findings provide fresh mechanistic insights into the regulation and proinflammatory role of LOX-dependent mechanical cues in diabetes while simultaneously implicating LOX as an alternative (downstream) target to block AGE/RAGE signaling in DR.

Article Highlights

We investigated the regulation and proinflammatory role of retinal endothelial lysyl oxidase (LOX) in diabetes. Findings reveal that LOX is upregulated by advanced glycation end products (AGE) and receptor for AGE (RAGE) and mediates AGE/RAGE-induced retinal endothelial cell activation and subendothelial matrix remodeling. We also show that LOX-dependent subendothelial matrix stiffening feeds back to enhance retinal endothelial RAGE. These findings implicate LOX as a key proinflammatory factor and an alternative (downstream) target to block AGE/RAGE signaling in diabetic retinopathy.

Objective

It has been hypothesized that SARS-CoV-2 infection in children can increase risk of developing type 1 diabetes. 

Research Design and Methods 

We undertook a prospective register-based analysis of children in Denmark where we investigated the association between SARS-CoV-2 infection and subsequent risk of type 1 diabetes. During the pandemic, Denmark had one of the highest test-rates per capita in the world and 90% of all Danish children were tested. 

Results

We did not observe a higher risk of a first time diagnosis of type 1 diabetes in children 30 days or more after a positive SARS-CoV-2 test, compared to children with a history of only negative SARS-CoV-2 tests (Hazard ratio 0.85, 95% CI 0.70, 1.04). 

Conclusions

Our data do not support that SARS-CoV-2 infection is associated with type 1 diabetes, or that type 1 diabetes should be a special focus after a SARS-CoV-2 infection in children.

The Fiqh of Hisab-Ru’ya in the Twentieth Century Indonesia: Study on the Thoughts of Hamka, Hasbi Ash-Shiddieqy, and Moenawar Chalil about the Unification of Hijri Calendar

Fiqh discourses regarding differences in methods and criteria (hisab and ru’ya) for determining the beginning of the Hijri months are still being debated among Muslims in Indonesia. Until now, there is no Hijri calendar that applies globally. The existing Islamic calendar is a local or regional calendar. The absence of a unified Hijri calendar often causes confusion in setting dates in Muslim society, and this makes Muslim intellectuals continue to study it. The idea of creating a unified Hijri calendar in Indonesia was originally raised by Hamka, Muhammad Hasbi Ash-Shiddieqy, and Moenawar Chalil. This research explores how the Hijri calendar is unified according to their opinions. This study is a qualitative research with a socio-historical and hermeneutic approach. Data collection uses the documentation method with the content analysis model. The results of this study indicate that Hamka believes that there needs to be a unified result between the hisab and the ru’ya methods, so that the Hijri calendar, especially the beginning of Ramadan and Shawwal, can become a fixed date. Meanwhile, Hasbi offers the idea that to overcome the differences in the beginning of Ramadan and Shawwal one must use the ru’yat method with global matla’. Meanwhile, Moenawar Chalil believes that the preparation of the Hijri calendar in Indonesia can only use the hisab method. These three ideas can be a solution in an effort to achieve uniformity of the Hijri calendar in Indonesia.
