Published: May 2022

This study evaluated the antidiabetic properties and biochemical changes in alloxan-induced diabetic rats treated with Moringa oleifera and Morinda lucida leaf extracts. The acute toxicity values of the extracts were determined before evaluating their antidiabetic effects in 7 groups of 4 rats each. Rats in groups 1-6 were made diabetic via a single injection of alloxan monohydrate (160 mg/kg i.p). Animals whose blood glucose levels rose to 200 mg/dl and above were considered diabetic and used for the study, but group 7 was the normal control. Groups 1 and 2 received 500 and 250 mg/kg of M. oleifera extract, respectively, while groups 3 and 4 received 500 and 250 mg/kg of M. lucida extract, respectively. Group 5 received 3 mg/kg of the standard drug (Daonil), while groups 6 and 7 were the diabetic and normal control groups, respectively. Treatment lasted for 21 days and was administered orally. The phytochemical screening results showed that each of the extracts was rich in phytochemical agents. Higher amounts of flavonoids and terpenoids were found in M. oleifera, while M. lucida had higher phenols and saponins. LD50 value obtained for each extract was above 5000 mg/kg. Results of the antidiabetic study indicated that the extracts significantly brought down glucose levels in the test rats (p<0.05) when compared with the diabetic control. Treatment also restored elevated lipids values, liver function, and renal function parameters in the diabetic rats. The decreased glutathione, catalase, and superoxide dismutase activities and increased lipid peroxidations resulting from diabetes mellitus induction were also significantly corrected following extracts administration when compared with the diabetic control (p<0.05). Our findings show that Moringa oleifera and Morinda lucida extracts may be safe for use in the management of diabetes mellitus and its associated biochemical complications.

Published: May 2022

Etlingera elatior (E. elatior) plant has long been used as a kitchen spice and daily food. E. elatior has potential as an antioxidant because it contains polyphenol and flavonoid compounds widely found in the leaves, fruit, and flowers. This study measures the total flavonoid content, total phenol content, and antioxidant activity using the ABTS method. Total phenol content was determined by the Follin-Ciocalteu method and total flavonoid content was determined by the Aluminium Chloride method. The results showed that the total flavonoid content from the highest to the lowest value from E. elatior was fruit extract, leaf extract, and flower extract, respectively. The value of total flavonoid content was 8.38 ± 0.15; 4.86 ± 0.10; and 2.60 ± 0.04 % w/w Catechin Equivalent (CE). The total phenol content from the highest to the lowest value from E. elatior was fruit extract, leaf extract, and flower extract, respectively. The total phenolic content values were 54.48 ± 1.89, 46.20 ± 0.83, and 4.80 ± 0.53 % w/w Gallic Acid Equivalent (GAE). The highest to lowest antioxidant activity values (IC50) were leaf extract at 58.82 ppm (strong activity), fruit extract at 103.05 ppm (moderate activity), and flower extract at 251.40 (weak activity), respectively.

Authors: Leyva-Figueroa Eugenio , Tovar-Díaz Jorge
Published: May 2022

La capacidad de recordar experiencias pasadas es sumamente importante, ya que nos permite tomar decisiones en el presente, dar ilación a nuestra vida y coherencia a nuestra personalidad. Sin embargo, las experiencias particularmente negativas generan memorias persistentes que pueden afectar nuestra salud mental, como en el caso del estrés postraumático. No obstante, al recordarse, el contenido de una memoria traumática puede cambiar, lo cual permite manipularla positivamente. La finalidad del presente escrito es describir la reconsolidación y la extinción, dos fenómenos neurobiológicos en los que una memoria se modifica tras su reactivación. Éstos subyacen a procedimientos clínicos como la exposición prolongada, ampliamente usada para tratar estrés postraumático.

Authors: Lavoie Marc , Seccareccia Mario
Published: May 2022

La teoría poskeynesiana es una de las numerosas escuelas de pensamiento heterodoxas en economía. En sus estudios sobre crecimiento y productividad, tiene varias similitudes con la teoría francesa de la regulación, que en Quebec y fuera de Francia es sobre todo conocida en los departamentos de ciencias políticas. En lo que toca a la teoría de precios y empresa, así como en la investigación del mercado laboral, se inspira en gran medida en el trabajo de economistas institucionalistas, tanto de Estados Unidos (EU), como del Reino Unido. Se hace una breve historia del surgimiento de la teoría poskeynesiana. Después, se evocará las principales características de la economía poskeynesiana.

Authors: Arundathi H.A. , Prakash N. , Halesh H.L. , Siddesh K.C.
Published: May 2022

Enterococci infections, have drawn attention of clinicians due to rapid increase in high level aminoglycoside resistance (HLAR). This resistance predicts failure of β-lactam antibiotic and aminoglycoside combination, which is the current treatment of choice for serious enterococci infections. This led us to investigate about the prevalence of HLAR enterococci in our hospital setting in Shimoga, Karnataka. All the clinical samples received at Microbiology laboratory, McGan hospital, Shivamogga between June 2016 and December 2016 was considered for the study. Enterococci were identified and further speciated by following conventional method. Antibiotic susceptibility pattern of all the isolates was determined according to CLSI guidelines. High level gentamicin resistance was detected by disc diffusion method using 120µg gentamicin disc. A total of 64 Enterococci species were isolated from the clinical specimens. On speciation, Enterococcus faecalis (E. faecalis) accounted for 72% (46) of the total isolates, 24%(16) of the isolates were Enterococcus faecium (E. faecium)and 4% (2) isolates were Enterococcus durans (E. durans). High level gentamicin resistance was noted in 42% (27) among the total isolates. E. faecium was found to be more resistant compared to E. faecalis. E. durans was a sensitive strain. Our study reconfirms the high prevalence of HLAR in the clinical setting. The study stresses on the need for regular screening of HLAR in all Enterococci infections and revise the battery of drugs for its treatment according to the report.

To reduce the efforts of humans, and to save time, this idea has been undertaken. The required hardware and software are easily available and easy to work with. This can lead the farmer for better consumtion of crops. As farmers can get benefits of the schemes that are available for them. If they have any problem or quetionary about the farming, then the farmers can take help of the application to contact with the other officers soo that he can get the desired benefit. In early days, these things were done manually, which needed lots of efforts so to avoid those efforts and extra consumtion of time this project has been undertaken. Doing all these things will bring transperancy between the farmers and the government. So no farmer will be left out from getting the benefits and schemes from the government. This willalso hepl framers in better utilization of the resources. Instead it will also provide the information on which, crop should farmer grow in order to gain the profit. This will allow real time information of crop sowing to be compiled in the application. As there will be increase in participation of the farmers in crop inspection, registration will help in facillating the process of settling crop insurance and crop inspection claims. It will also make it easier for farmers to get peak loans. If the farmers face some losses due the issues like crop damage due to the natural calamities, the government will help them in resolving the same. Keywords: E-survey perception, E-government.

Abstract: Neural Cryptography is a new thread that integrates cryptography and neural networks for cryptanalysis and encryption applications. We show that Neural Networks can execute symmetric encryption in an adversarial context in this paper, and we build on the existing literature on the subject. Cryptography's purpose is to make it difficult to decipher a cypher and recreate the plain text without the associated key. Your messages are encrypted with excellent cryptography in such a way that brute force attacks against the algorithm or key are nearly impossible. Good cryptography is secure because it employs extremely long keys and encryption techniques that are resistant to various types of attack. The neural net application is the next step in the evolution of good cryptography. This paper discusses the use of neural networks in cryptography, including how to create neural networks that can be utilized in cryptography. Keywords: Cryptography key, encryption system, encryption algorithm, artificial neural network,chaos maps, logistic encryption.

Abstract: Electric cars square measure associate interest within the market. Today, existing braking technologies are used. This braking technology consumes tons of energy throughout braking within the style of heat. Therefore, regenerative braking is that the most significant methodology of focusing as a result of it's associate energy saving methodology. Increase the potency of electrical vehicles by reducing waste of energy. In electrical vehicle regenerative braking mode, the K.E. of the wheels is bornagain into electricity and keep within the battery or electrical condenser. This methodology has been improved mistreatment flywheels, DC-DC converters. Once a quick moving vehicle is applied a brake the momentum energy is wasted. The brake energy converter could be a compact system mounted in cylinder that absorbs this power and converts it to electricity that may be keep in battery for more use. Compact, efficient, low value and recycles energy nicely, prevents wastage. This method fits within the vacant house of the drum brakes of auto as a result of currently day's disk brakes square measure used. Low weight, compact size and power is made altogether four wheels of the vehicle. Straightforward construction, low value and straightforward to use. Absorbs brake power that the load on the hydraulic brakes is reduced thus less wear of brakes. Motor is within the earlier models with a centralized battery unit, system power to weight magnitude relation is extremely low, i.e., low power is made as compared to the burden of the system. Braking potency is low and tends to explosive brake in emergency conditions. Keywords: Energy, Brake, Electricity, Flywheel, Vehicle.
Workplace relationships and employees' proactive behavior: Organization-based self-esteem as a mediator
Authors: Su Xiao-Ying , Wang Ling-Yun , Zhang Long
Published: May 2022

We utilized self-determination theory to understand employees' proactive behavior. Assuming that organization-based self-esteem (OBSE) is a key variable influencing employees' satisfaction status, we proposed that leader–member exchange (LMX) and team–member exchange (TMX)
would affect employees' proactive behavior through their OBSE, and that LMX and TMX would interact, whereby TMX would increase proactive behavior through affecting OBSE when individuals experience low-quality LMX. Data were collected from 315 employees in a Chinese company. The results show
that workplace relationships positively affected OBSE and employees' proactive behavior, and OBSE played a mediating role in these relationships. TMX increased employees' OBSE and proactive behavior under the condition of low-quality LMX. Our results highlight the consequences of workplace
interpersonal interactions on OBSE and proactive behavior. Practical solutions for enhancing employee motivation are recommended.
Impact of effort–reward imbalance on undergraduates' aggressive behavior: The mediating role of perceived justice and hostile attribution
Authors: Chu Kequn , Zhu Fengshu
Published: May 2022

Effort–reward imbalance can predict aggressive behavior, but the mechanism of its influence is not yet clear to researchers. Thus, in this study we explored the mediating roles of perceived justice and hostile attribution in the relationship between effort–reward imbalance
and aggressive behavior in an educational setting. Using the Effort–Reward Imbalance Scale for University Students, the Chinese version of the Perceived Justice Scale for College Students, the hostile attribution subscale of the Social Information Processing Attribution Bias Questionnaire,
and the Chinese version of the Buss and Perry Aggression Questionnaire, we conducted a survey with 1,660 Chinese undergraduates. The results show that perceived justice played a mediating role in the relationship between effort–reward imbalance and aggressive behavior, as did hostile
attribution. In addition, perceived justice and hostile attribution had a chain mediating effect in the link between effort–reward imbalance and aggressive behavior. Thus, effort–reward imbalance affects aggressive behavior not only directly but also indirectly through perceived
justice and hostile attribution. Our findings enrich the literature on aggressive behavior by helping to understand how individuals become aggressive after the frustrating experience of receiving insufficient reward for their efforts.
Reactions of Chinese "drifting elderly" aged 50 years and over when facing negative experiences in urban living
Authors: Ruan Yuhui , Zhou Linyi
Published: May 2022

Our aim was to analyze and interpret the behavioral reactions of Chineselaopiao(drifting elderly), that is, people aged 50 years and over who have migrated from rural to urban areas to rejoin adult sons/daughters, and who face negative experiences as a result of this move. We employed grounded theory and interviewed 31 migrants living in Shanghai. Most participants showed an obvious bias when facing negative experiences: they prioritized the future over the present, were accepting of present losses, and expressed risk aversion regarding future gains. Regarding the present, participants expressed a relatively weak desire for anticipatory gains and a positive attitude regarding risks. In contrast, regarding the future, they expressed a strong desire for anticipatory gains and a strong desire to delay related risks. Therefore, for the sake of future gains and to avoid greater risk, they continued to live as drifting elderly even when they were currently facing some seemingly negative social consequences.
Deep Learning of Quantum Many-Body Dynamics via Random Driving
Authors: Mohseni Naeimeh , Fösel Thomas , Guo Lingzhen , Navarrete-Benlloch Carlos , Marquardt Florian
Published: May 2022

Neural networks have emerged as a powerful way to approach many practical problems in quantum physics. In this work, we illustrate the power of deep learning to predict the dynamics of a quantum many-body system, where the training is based purely on monitoring expectation values of observables under random driving. The trained recurrent network is able to produce accurate predictions for driving trajectories entirely different than those observed during training. As a proof of principle, here we train the network on numerical data generated from spin models, showing that it can learn the dynamics of observables of interest without needing information about the full quantum state. This allows our approach to be applied eventually to actual experimental data generated from a quantum many-body system that might be open, noisy, or disordered, without any need for a detailed understanding of the system. This scheme provides considerable speedup for rapid explorations and pulse optimization. Remarkably, we show the network is able to extrapolate the dynamics to times longer than those it has been trained on, as well as to the infinite-system-size limit.
Ieskats latviešu trimdas kalendārniecībā (personības un tendences)
Authors:   Latvijas Universitāte, Zanders Viesturs
Published: May 2022

The publishing of calendars in Latvian language began already in the middle of the 19th century. However, with some exceptions, this phenomenon has not gained sufficient attention of the specialists in the field. The same can be said concerning the calendars in Latvian published after the WWII by Latvian communities in exile. Due to objective reasons, the range of the calendars published in exile is not as wide and varied as in Latvia before occupation. Nowadays, the only value many of them still retain is that of a testimony of their specific time and cultural situation. Nevertheless, one can find calendars intended not just for some recreational reading and those have an enduring place in the history of calendars published in Latvian. Some of them bear the characteristics of one-man enterprise: e.g., Bitītes kalendārs (The Bee’s Calendar) (Eslingen, Germany, 1946–1958) composed by the Archbishop of the Latvian Evangelical Lutheran Church Teodors Grīnbergs (1870–1962) or Ārstniecības kalendārs (Calendar for Treatment) (Chicago, USA, 1954–1964) composed by Dāvids Bīskaps (1879–1972). In case of some others, we find a more extensive group of authors and the touch of an experienced editor, e.g., P. Mantinieka apgāda gada grāmata (The Annual of P. Mantinieks’ Publishing House) (Brussels, Belgium, 1950–1952) composed by Arturs Bērziņš (1882–1962) or Latviešu almanahs (Latvian Almanac) (London, Great Britain, 1952–1957), as well as Dzimtenes kalendārs (The Calendar of Motherland) (Vesterosa, Sweden, 1972–1988) compiled by Kazimirs Vilnis (1907–1988), a Catholic dean. There is a special place in the history of calendars published in Latvian for Tāvu zemes kalendars (Fatherland’s Calendar), published by Vladislavs Locis (1912–1984). Its publication started already at the end of the 1930s still in Latvia, afterwards it was continued in Germany, and finally, in 1991, resumed in Latvia.
Towards Causal Effect Estimation of Emotional Labeling of Watched Videos
Authors: Pereira Eanes Torres , Do Nascimento Silva Geovane
Published: May 2022

Emotions play a crucial role in human life, they are measured using many approaches. There are also many methodologies for emotion elicitation. Emotion elicitation through video watching is one important approach used to create emotion datasets. However, the causation link between video content and elicited emotions was not well explained by scientific research. In this article, we present an approach for computing the causal effect of video content on elicited emotion. The Do-Calculus theory was employed for computing causal inference, and a SCM (Structured Causal Model) was proposed considering the following variables: EEG signal, age, gender, video content, like/dislike, and emotional quadrant. To evaluate the approach, EEG data were collected from volunteers watching a sample of videos from the LIRIS-ACCEDE dataset. A total of 48 causal effects was statistically evaluated in order to check the causal impact of age, gender, and video content on liking and emotion. The results show that the approach can be generalized for any dataset that contains the variables of the proposed SCM. Furthermore, the proposed approach can be applied to any other similar dataset if an appropriate SCM is provided.
Vehículos eléctricos, una opción viable para Colombia
Authors: Salazar Marín Edgar Alonso
Published: May 2022

Este libro es la expresión escrita de una percepción real. La movilidad eléctrica es y será una alternativa cada vez mas viable en nuestro país y en Latinoamérica. El inminente daño ambiental y social que ha generado la humanidad con un desarrollo poco sustentable, con sobrepoblación y un consumo desmedido y con la alta generación de gases efecto invernadero, ha hecho que países desarrollados se preocupen por proponer medidas que busquen mitigar los impactos negativos de un efecto ya prácticamente irreversible. La movilidad eléctrica es apenas un aporte necesario de una gran matriz de factores como eficiencia energética, consumo sustentable, economía circular, smart grids, y smart cities. Mas de 6000 vehículos eléctricos en las calles colombianas y múltiples investigaciones han desmitificado la duda de la gran eficiencia y capacidad que tiene un vehículo eléctrico comparado con el de combustión. Los gases derivados de un combustible fósil no solo aportan al cambio climático, sino que generan polución, fuente principal de gran cantidad de enfermedades pulmonares, además del estrés por ruido de los motores térmicos. Las políticas de gobierno han favorecido el impulso hacia el mercado del eléctrico, pero faltan mayores incentivos y concretar proyectos de implementación masificada de estaciones de carga eléctrica.
Botrytis cinerea activates virulence-related metabolism in the interaction with tolerant green grapes

Published: May 2022

Botrytis cinerea is responsible for the gray mold disease,
severely affecting Vitis vinifera grapevine and hundreds of other
economically important crops. However, many mechanisms of this
fruit-pathogen interaction remain unknown. The combined analysis of the
transcriptome and metabolome of green fruits infected with B.
cinerea from susceptible and tolerant genotypes was never performed in
any fleshy fruit, mostly because green fruits are widely accepted to be
resistant to this fungus. In this work, peppercorn-sized fruits were
infected in the field or mock-treated, and infected berries were
collected at green (EL32) stage from a susceptible (Trincadeira) and a
tolerant (Syrah) variety. RNAseq and GC-MS data suggested that Syrah
exhibited a pre-activated/basal defense relying on specific signaling
pathways, hormonal regulation, specifically jasmonate and ethylene
metabolism, and linked to phenylpropanoid metabolism. In addition,
putative defensive metabolites such as shikimic, ursolic/ oleanolic, and
trans-4-hydroxy cinnamic acids, and epigallocatechin were more
abundant in Syrah than Trincadeira before infection. On the other hand,
Trincadeira underwent relevant metabolic reprogramming upon infection
but was unable to contain disease progression. RNA-seq analysis of the
fungus in planta revealed an opposite scenario with higher gene
expression activity within B. cinerea during infection of the
tolerant cultivar and less activity in infected Trincadeira berries. The
results suggested an activated virulence state during interaction with
the tolerant cultivar without visible disease symptoms. Together, this
study brings novel insights related to early infection strategies of
B. cinerea and the green berry defense against necrotrophic
fungi.

A Comparative Analysis of Step Loading and Staircase Testing for Fatigue Strength Estimation of an Engine Component
Authors: Thompson Todd , Liu Jinqiang , Hu Chao
Published: May 2022

Staircase testing is a standard method for evaluating the fatigue
strength of components. However, staircase testing assumes a normal
distribution, while components can display bimodal behavior due to flaws
in material, or issues during the manufacturing process. Three unique
step loading data sets on different production crankshafts provide
evidence that step loading reliably identifies material or manufacturing
issues, that lower a component’s fatigue strength. Staircase testing has
an 87% or greater chance of overestimating the component’s fatigue
strength, which in turn overestimates the component’s expected
reliability. For example, a component with a 99.9% reliability, based
on staircase testing would only have a 74% reliability based on step
loading. If a component contains an undetectable manufacturing defect,
staircase testing has a 99% chance of overestimating the component’s
fatigue strength. Step loading reliably improves the estimation of a
component’s fatigue strength distribution while providing insights into
a component’s defect tolerance.

Private Eyes and “Little Helpers”: Doormen, Gatekeepers, and Racial Trespass in Chandler's Farewell, My Lovely and Mosley's Devil in a Blue Dress
Authors: Brooks George English
Published: May 2022

Raymond Chandler's and Walter Mosley's protagonists move through different neighborhoods of midcentury Los Angeles and interact with various "gatekeepers" whose function is to maintain and reinforce the racialized urban boundaries of access between LA's neighborhoods, institutions, and other highly regulated public and private spheres. These encounters illuminate anxieties about the stability of racial categories, the physical urban space that these categories would control and organize, and notions of racial and class mobility in midcentury America.
The Charged Strolls of the Brown Flâneuse in Sandra Cisneros's “The House on Mango Street”
Authors: Saber Yomna
Published: May 2022

This essay shifts the perspective oí flânerie from the European metropolis and the white flâneur, and suggests that the protagonist of Sandra Cisneros's The House on Mango Street can be categorized as a flâneuse through her fluid stroll in a Chicagoan barrio. Cisneros's novel introduces re-conceptualizations of flânerie by presenting a Chicana stroller whose Odyssey comes across additional social, cultural, and economic afflictions particular to the inner city. Her flânerie falls into three main configurations: mapping ethnicity, mapping gendered spaces, and mapping identity. The analysis is anchored by Walter Benjamin's work on flânerie and recent revisions of the term in the works of Keith Tester and Anne Friedberg.
