Peroxidase (POD) associated with the browning of fresh-cut fruits and vegetableswas extracted from purple skin eggplant(Solanum melongena L.) and characterised using reliable spectrophotometric methods. Maximal POD activity was found at 35 Â°C and pH 6.0 with guaiacol as the substrate. The enzyme was stable at his optimal temperature (35 Â°C) and hisat pH stability was in the range of 5.6 - 6.6.Peroxidase retained its full activity in the presence of ion K+, Cu2+, Na+, Pb2+ and Ba2+ but were inhibited strongly by the ion Fe2+ and Mg2+ and the reducing agents as sodium thiosulfateand ascorbic acid. Effect of heattreatment on eggplant peroxidase showed that D-values decreased with increasing temperature, indicating faster peroxidase inactivation at higher temperatures.At 60 Â°C, the D-values ranged from 20.42 to 54.24 min. Hence, heat treatment at 60 Â°C for 30 min reduced browning of eggplant fruit.These data can be used to predict prevention of browning in the purple skin eggplantby thermal inactivation and the use of chimical agents onthe enzyme.

Authors: a Damaris , Monari Gesare
Published: May 2021

The study focused on the utilization of human resource management practices in enhancing service delivery among state corporations in Kenya. Critique of existing literature on the human resource management practices revealed that only few studies have focused on the relationship between human resource management practices and service delivery. This study, therefore, was guided by two variables namely: reward and recognition programs and HR audits as human resource management practices and their influence on service delivery in State Corporations in Kenya. The study adopted a descriptive survey research design to gather data from the sampled respondents of the state corporations. Stratified random sampling was applied to select respondents from the state corporations to participate in the study. Information was gathered by use of questionnaires which were subjected to a pre-test to ensure both validity and reliability. Data analysis was done using both descriptive and inferential statistics with the aid of analysis tool statistical package for social Sciences (SPSS). The study found that reward and recognition programs have a positive influence on service delivery among state corporations in Kenya. Further, HR audit practices were found to have a significant positive effect on service delivery. The implication is that adoption of these hrpractices can drive service delivery in state corporations.Itis, therefore, recommended that state corporations in Kenya put in place appropriate reward and recognition programs and periodically carry out HR audits since they significantly influence service delivery.

Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, morals, beliefs, and habits. Educational methods include teaching, training, storytelling, discussion and directed research. In ancient India, both formal and informal ways of education system existed. Indigenous education was imparted at home, in temples, Pathshalas, Tolas, Chatuspadis and Gurukuls. There were people in homes, villages and temples who guided young children in imbibing pious ways of life. A Gurukula or Gurukulam is a type of education system in ancient India with Shishya (students or disciples) living near or with the guru, in the same house. At the end of ones education, a Shishya offers the Gurudakshina before leaving the Gurukula.Over a period of time two system of education developed, the Vedic and the Buddhist. As the name indicates in the former system Vedas, Vedanta, Upanishads and other allied subjects were taught while in the latter system, thoughts of all the major school of Buddhism was taught.Vidyapeeth was the place of spiritual learning founded by great Acharya, Sri Shankara in places like Sringeri, Kanchi, Dwarka, and Puri, etc. Agraharas was an institution of Brahmins in villages where they used to teach.Modern education is very different from the traditional education.AryaSamajwas founded by Maharishi DayanandSaraswati on 10 April 1875.The traditional education and the modern education, both should be given equal importance.

The internet today is a universal entity whose nature cannot be quickly defined. The internet has provided essential services in the education sector. Perhaps, people in academia rely heavily on the internet for academic purposes. However, observation suggests that a large number of students use the internet for purposes other than academics. The present study aimed to determine the differences in internet use for social or academic purposes among undergraduates in tertiary institutions in Nigeria. A total of two hundred undergraduates comprising male and female drawn from three tertiary institutions participated in the study. The participants completed a self-report measure on internet use for academic and non-academic purposes. A 2x2 contingency Chi-square analysis revealed that female participants used the internet more for non-academic purposes when compared to their male counterparts. A one-way ANOVA showed that the participants differ significantly on the use of the internet for academic purposes according to their levels of study. Discussion and conclusions are discussed.

Bone remodeling markers and their role in oncology
Authors: Golounina O. O. , Belaya Zh. E.
Published: May 2021

Bone metastases are a common complication of cancer. Patients with bone metastases may have experienced skeletal-related events, such as hypercalcemia, pathological fractures, pain syndrome of varying intensity, spinal cord compression with negative effects on the quality of life. Current diagnostic tools have some limitations, such as high cost and limited availability in the distant areas, as well as falls negative and falls positive results. In this aspect, non-invasive sensitive markers of bone metabolism might give additional valuable information. Bone remodeling markers (N-terminal propeptide of type 1 collagen, osteocalcin, C-terminal telopeptide of type 1 collagen, etc.) have been used for a long time to predict the effectiveness of osteoporosis treatment; as additional risk factors for treatment initiation in patients with osteoporosis, in diagnostic search for secondary forms of osteoporosis; and as predictors of fracture in population studies. This review summarizes the clinically relevant biochemical markers of bone remodeling and the available evidence for their use in the metastatic bone disease in particularly in the diagnosis and prognosis of bone metastases risk and skeletal complications, predicting clinical outcomes, bone disease progression and overall survival. It has been shown that a sufficient suppression of bone remodeling biochemical markers while on treatment with bisphosphonates is associated with an improvement in survival and a decrease in the risk of skeletal complications in patients with bone metastases. New data may become a rational basis for wider use of bone metabolism markers in oncological practice. However, it is necessary to standardize and validate the determination of bone markers and verification of cut-off diagnostic values for their introduction into the routine clinical practice of patients with malignancy.
Adherence to somatostatin analog therapy for acromegaly
Authors: Ilovayskaya I. A.
Published: May 2021

The main goals of treatment for many diseases are to improve the prognosis of diseases and to enhance the quality of life. Among the barriers that restrict achieving these goals we have to mention adherence to treatment. Patients with chronic diseases, including acromegaly, are at increased risk of poor adherence to treatment. The duration of supervision of patients with acromegaly in most cases exceeds 25-30 years, which makes the issue of adherence to treatment extremely important.

One of the main goals of the acromegaly treatment is to achieve the target values of STH and IGF-1, which ensures the regression of most clinical symptoms and restoration of life expectancy. For this purpose, a significant proportion of patients with acromegaly receive somatostatin analog treatment - as a second line of treatment after non-radical neurosurgical intervention, or as the first line of treatment if neurosurgical intervention could not be performed for any reason. Adherence to treatment is influenced by socio-economic factors, the characteristics of the drug, and the characteristics of the patient. Recent studies have shown that the easy administration of lanreotide provides better treatment adherence than octreotide. Factors that can reduce adherence to the treatment of acromegaly are old age, mental disorders, subjective opinion about the low quality of life, the need to visit medical institutions to administer the drug. On the contrary, the ability to perform subcutaneous injections (on their own or with the help of relatives) without visiting medical facilities, providing accessible information about the disease and the need for its treatment significantly increases adherence to treatment. It is necessary to continue research on the factors and methods of increasing adherence to drug treatment of acromegaly.
COVERAGE OF INTERMOLECULAR FORCES IN ORGANIC CHEMISTRY TEXTBOOKS
Authors: Júnior José , Oliveira José , Alexandre Francisco , Junior Antonio
Published: May 2021

The paper analyzes fifteen organic chemistry textbooks commonly used in Brazilian universities to examine intermolecular forces’ coverage in them. The findings revealed that the intermolecular forces are spread over a few pages (less than 1%) in a fragmented way, and over several chapters that do not provide enough information to help create a clear image in the student’s mind. Thirteen textbooks contained end-of-chapter problems related to intermolecular forces. However, less than 1.3% of the total (212) are associated with intermolecular forces. This deficient approach to intermolecular forces in Organic textbooks can lead to teachers’ lack of interest in teaching the subject, leading to students failing to learn this important organic chemistry topic

Authors: Nurhan Ahmad Dzulfikri , Gani Maria Apriliani , Maulana Saipul , Siswodihardjo Siswandono , Ardianto Chrismawan , Khotib Junaidi
Published: May 2021

Background:

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused
a global pandemic and emergency. Currently, there is no therapeutic agent that has been proven effective
against the virus.

Objective:

We investigated and screened for 401 antiviral compounds that could inhibit one or more
of the three protein targets in SARS-CoV-2 chymotrypsin-like (3CL) protease, RNA-dependent
RNA polymerase, and spike glycoprotein) using the in-silico approach.

Methods:

Lipinski’s rule of five was used as an initial screening for relevant compounds. Ligand
preparation was conducted using JChem software and Schrödinger’s LigPrep module, while protein
elucidation was conducted using AutoDockTools-1.5.6. Molecular docking was analyzed using AutoDockVina.

Results:

Five antiviral compounds were obtained from each SARS-CoV-2 protein with ideal and
potential binding energy as a candidate for target protein inhibition on SARS-CoV-2, TAK-981;
lopinavir, mefloquine, and sitagliptin were potent inhibitors of 3CL protease; imatinib, relacatib,
AZD7986, imatinib, and TAK-981 proteins showed potential as inhibitors of RdRp tetrandrine, and,
selinexor, imatinib, lopinavir, and ciclesonide, showed potential as inhibitors of glycoprotein
AZD7986. These compounds have better binding energy than the three comparator drugs,
remdesivir, chloroquine, and hydroxychloroquine.

Conclusion:

We obtained several antiviral compounds with reliable binding energies to the SARSCoV-
2 proteins and potentially better efficacy than the three comparator drugs. Furthermore, this
research will help accelerate the development of Covid-19 drugs.

Background:

The complication of Alzheimer’s disease (AD) has made the development of its therapeutic a challenging task. Even after decades of research, we have achieved no more than a few years of symptomatic relief. The inability to diagnose the disease early is the major hurdle behind its treatment. Several studies have aimed to identify potential biomarkers that can be detected in body fluids (CSF, blood, urine, etc.) or assessed by neuroimaging (i.e., PET and MRI). However, the clinical implementation of these biomarkers is incomplete as they cannot be validated.

Method:

This study aimed to overcome the limitation of using artificial intelligence along with technical tools that have been extensively investigated for AD diagnosis. For developing a promising artificial intelligence strategy that can diagnose AD early, it is critical to supervise neuropsychological outcomes and imaging-based readouts with a proper clinical review.

Conclusion:

Profound knowledge, a large data pool, and detailed investigations are required for the successful implementation of this tool. This review will enlighten various aspects of early diagnosis of AD using artificial intelligence.

Influence of COVID-19 Lockdowns on the Usage of a Vision Assistance App Among Global Users With Visual Impairment: Big Data Analytics Study (Preprint)
Authors: Luo Gang , Pundlik Shrinivas
Published: May 2021

BACKGROUND

Millions of individuals with visual impairment use vision assistance apps to help with their daily activities. The most widely used vision assistance apps are magnifier apps. It is still largely unknown what the apps are used for. Lack of insight into the visual needs of individuals with visual impairment is a hurdle for the development of more effective assistive technologies.

OBJECTIVE

This study aimed to investigate how needs for visual aids may vary with social activities, by observing the changes in the usage of a smartphone magnifier app when many users take breaks from work.

METHODS

The number of launches of the SuperVision Magnifier app was determined retrospectively from 2018 to 2020 from among active users worldwide. The fluctuation in app usage was examined by comparing weekday vs weekend periods, Christmas and new year vs nonholiday seasons, and COVID-19 lockdowns vs the easing of restriction during the pandemic.

RESULTS

On average, the app was used 262,466 times by 38,237 users each month in 2020 worldwide. There were two major trough points on the timeline of weekly app usage, one aligned with the COVID-19 lockdowns in April 2020 and another aligned with the Christmas and new year week in 2018 and 2019. The app launches declined by 6947 (11% decline; P<.001) during the lockdown and by 5212 (9% decline; P=.001) during the holiday weeks. There was no significant decline during March to May 2019. App usage compensated for seasonal changes was 8.6% less during weekends than during weekdays (P<.001).

CONCLUSIONS

The need for vision assistance technology was slightly lower during breaks and lockdowns, probably because the activities at home were different and less visually demanding. Nevertheless, for the entire user population, the needs for visual aids are still substantial.
The Alchemy of Equality Rights
Authors: Sealy-Harrington Joshua
Published: May 2021

A clear legal test for equality is impossible, as it should be. Indeed were the test clear, it could not be for equality. It would have to be for something other than equality — in effect, for inequality. The abstract character of equality is not a new idea. In fact, the Supreme Court of Canada’s first decision under section 15 of the Canadian Charter of Rights and Freedoms1 recognized equality as “an elusive concept” that “lacks precise definition.”2 Why, then, do judges continue to demand such definition over thirty years later? The answer, at times, is politics.

Comment on Fraser v Canada (AG): The More Things Change
Authors: Moon Richard
Published: May 2021

Very early in my academic career I wrote two pieces about section 15.1 The first was written in 1987, before the Supreme Court of Canada had heard any section 15 cases,2 and the second in 1989 was a comment on Andrews v Law Society of British Columbia, the first of the Court’s section 15 decisions.3 When I re-read these pieces recently it struck me that with a few minor updates they could be read as comments on the Court’s recent decision in Fraser v Canada(Attorney General). 4 The same issues and tensions that were there at the beginning of section 15 are still there. They are built into the concept of constructive/effects discrimination and are not about to disappear. Shamelessly, I have reconstituted these two earlier pieces into a comment, of sorts, on the Fraser case. Other contributors in this special issue of the Constitutional Forum have set out the facts of the Fraser case and so I have not done so here.

Published: May 2021

Utilizando las mediciones realizadas durante el Primer Experimento Global del GARP (FGGE) en diferentes condiciones geográficas, se discuten las propiedades radiativas de las nubes estratiformes. Se describen sus rasgos característicos, en particular las características radiativas espectrales y totales de estas nubes sobre áreas urbanas y rurales, la cubierta de hielo del Artico y cuerpos acuosos en dependencia del espesor óptico de las nubes y la elevación del Sol. Asimismo se analiza la dependencia de la emisividad de las nubes y su espesor en latitudes altas, medias y tropicales. La variabilidad de las propiedades radiativas de las nubes estratos en diferentes condiciones, requiere de un mayor cúmulo de datos observacionales y búsqueda de técnicas para su parametrización al considerar la interacción entre las nubes y la radiación en el modelado numérico de la circulación general y del clima. Los resultados muestran que el albedo total de las nubes es algo menor que su albedo en el visible, sin embargo, con una precisión cercana al 10 por ciento, éstos pueden considerarse idénticos, lo cual es esencial para la energética radiativa de la atmósfera. Las nubes bajas se caracterizan por absorción de radiación de onda corta, no solamente en las bandas de absorción molecular sino también en el espectro visible. Como regla general, el calentamiento de las nubes inducido por absorción es menor que el enfriamiento debido al intercambio de calor radiativo, con excepción_de nubes sobre grandes áreas industriales, en las regiones de incendios de bosques y de nubes interaccionando con aerosoles ópticamente activos en el caso de transportes masivos de polvo de los desiertos. La absortividad de las nubes sobre el agua, áreas rurales y hielo, no excede 0.05 ... 0.15, pero para nubes ópticamente espesas con r > 30, puede llegar a 0.20 . . . 0.30. El albedo, A, de una atmósfera nubosa sobre cuerpos acuosos disminuye al aumentar la latitud, con un razón de cambio cercana a 0.003 km-1; y sobre el mar cercana a 0.01 km-1. Para una elevación del Sol he= 15 - 18°, el gradiente ^A/^he cambia de signo, lo cual se conecta con el efecto de la macro-inhomogeneidad de las nubes para elevaciones bajas del Sol. Los resultados de comparar datos calculados con observaciones de la evolución de niebla advectiva y nubes sobre hielo, así como experimentos complicados subsatelitarios, indican la necesidad de considerar la divergencia radiativa del flujo de calor en una atmósfera nubosa. Se encuentra una disminución de ésta, por fuera de la emisividad de las nubes, en las altas latitudes, al compararla con la divergencia en las latitudes medias y tropicales. Los datos sobre la dependencia de la emisividad de las nubes se expresan con su espesor óptico y nivel.
On The analysis of seasat winds

Published: May 2021

Se formuló un método para analizar los vientos de SEASAT-A el cual elimina la ambigüedad en la medición de los vientos de SEASAT. La ambigüedad se eliminó usando vientos estimados a partir del movimiento de nubes bajas y dé patrones sinópticos de nubes (basados en fotos de satélite), de climatología de vientos de superficie así como de principios de continuidad en espacio y tiempo. El método se aplicó a datos de SEASAT tomados sobre el Atlántico Tropical. La exactitud del método ha sido evaluada comparando los resultados de nuestra técnica de análisis con observaciones independientes de barcos. La comparación muestra que la técnica de análisis produjo vientos que son comparables en exactitud a la de los vientos reportados por los barcos.
Una interpretación geométrica de las funciones ortogonales empíricas
Authors: Peña H. G. , Badan-Dangon A.
Published: May 2021

Se presenta una interpretación geométrica sencilla de las Funciones Ortogonales Empíricas cuando sus dos primeros modos explican un gran porcentaje de la varianza total (por ejemplo, un 90%). La representación geométrica en dos dimensiones (plano), permite obtener una inspección rápida, informativa y resumida de la interrelación entre las variables iniciales. Se estiman los errores relativos que se cometen al despreciar la influencia del tercer modo. Estos conceptos son aplicados a una serie de datos de corrientes marinas obtenidas a distintas profundidades. La interpretación geométrica puede extenderse a más de 2 dimensiones, aunque su visualización, obviamente, se hace cada vez más difícil.

Published: May 2021

This study has two purposes, the first is describing how the teacher’s preparation the instructional media and the second one is explaining how the teacher’s utilized the instructional media in teaching English to young learners. This study was conducted in SDN Baros Mandiri 3 Cimahi at fifth-grade students. To collect the data the researcher used observation in the classroom and interview with the English teacher. This method used a descriptive qualitative. The result of this study showed that in preparing the instructional media the teacher did two kinds of preparation. The English teacher’s stated that the preparation was: first, selecting the suitable instructional media related to the material that will be taught. Second, mastering the material for delivering to students. The instructional media used by the English teacher’s is flashcards, the English teacher’s stated that flashcards are mostly because it doesn’t need a lot of preparation. Flashcards are also useful to help the teacher in the learning process because the students can visualize the words through seen at the flashcards. The use of flashcards also easy, the teacher only needs to show one by one of the pictures to all students and they would be guessed the name of the pictures related to the material, students who can guess will come to the front of the class and write down the word in English.
Notas acerca da eduação escolar quilombola no Brasil
Authors: Kunhavalik Vangéria Teixeira , Santos Arlete Ramos dos
Published: May 2021

Este artigo é fruto de uma pesquisa realizada no âmbito da especialização em Políticas Públicas e Gestão Educacional pela Universidade Estadual do Sudoeste da Bahia. Objetivou apresentar uma breve discussão acerca das implicações do capitalismo na educação quilombola na sociedade brasileira. Neste estudo fizemos uso do método denominado de Materialismo Histórico Dialético de Karl Marx, para quem a sociedade brasileira é capitalista e esse sistema é produtor de contradições e de desigualdades sociais. A Educação Escolar Quilombola, apesar da sua imensa importância para atender comunidades remanescentes, povo historicamente excluído e desassistido, nem sempre é contemplada pois as políticas implementadas têm favorecido os interesses do capital. Para ser possível uma Educação Escolar Quilombola comprometida com as lutas dos remanescentes quilombolas, além de intensificar a busca por cidadania, é preciso que os(as) educadores(as) estejam interessados(as) em construir novas posturas e práticas pedagógicas.
Lei de Responsabilidade Fiscal e os investimentos em educação nos municípios da Bahia (2007-2011), Brasil: uma contradição institucional
Authors: Silva Filho Penildon
Published: May 2021

A Lei de Responsabilidade Fisca (LRF) objetivou normatizar limites para a gestão pública em vários aspectos, inclusive nos gastos com folha de pessoal. Por outro lado, o Fundeb aumentou em 1400% a partir de 2007 as transferências da União para os estados e municípios. Essas duas leis se encontram em contradição, pois a LRF estabelece um limite máximo de gastos com pessoal, enquanto o Fundeb estabelece um mínimo de investimento em profissionais da Educação superior àquele limite permitido pela LRF. Avaliamos o cumprimento da LRF e o cumprimento das exigências legais de aplicação de recursos na área de Educação, no cumprimento do Piso Nacional dos profissionais do magistério e nas políticas de valorização do magistério nos municípios da Bahia. Foi realizada uma pesquisa com os relatórios do Tribunal de Contas dos Municípios da Bahia entre 1997 e 2011. Verificamos se há associação entre o cumprimento da LRF com o constrangimento da aplicação dos recursos da Educação e no cumprimento da Lei do Fundeb. Há duas tendências marcantes na evolução dos pareceres desse tribunal: Há uma diminuição das aprovações e aprovações com ressalvas ao longo do tempo, e o consequente aumento das reprovações; nos anos 2007 a 2010, a partir da promulgação do Fundeb e da Lei do Piso Salarial, houve um crescimento expressivo das reprovações das contas no item do cumprimento da LRF, indicando uma associação entre essas variáveis.

Numerous studies have unsuccessfully tried to unravel the definitive
host of the coccidian parasite Besnoitia besnoiti. Cattle
infections by B. besnoiti cause a chronic and debilitating
condition called bovine besnoitiosis that has emerged in Europe during
the last two decades, mainly due to limitations in its control
associated to the absence of vaccines and therapeutical tools. Although
the exact transmission pathway of B. besnoiti is currently
unknown, it is assumed that the parasite might have an indirect life
cycle with a carnivore as definitive host. Current lack of studies in
wildlife might underestimate the importance of free-living species in
the epidemiology of B. besnoiti. Thus, the aim of the present
study is to assess the presence of Besnoitia spp. in free-ranging
mesocarnivores in Spain. DNA was searched by PCR on faeces collected
from wild carnivores as a first approach to determine which species
could be considered as potential definitive host candidates in further
research. For this purpose, a total of 352 faecal samples from 12
free-living wild carnivore species belonging to the Canidae, Felidae,
Herpestidae, Mustelidae, Procyonidae, and Viverridae families were
collected in seven Spanish regions. PCR testing showed that
Besnoitia spp. DNA was present in four faecal samples from red
foxes collected in western Spain, an area with the greatest density of
extensively reared cattle and associated to high incidence of bovine
besnoitiosis in the country. To date, this is the first report of a
Besnoitia besnoiti-like sequence (99.57% homology) from
carnivore faeces in a worldwide context. Red foxes might contribute to
the epidemiology of B. besnoiti, although further studies, mostly
based on bioassay, would be needed to elucidate the accuracy and extent
of these interesting findings.
