Authors: Ghasempour Roghayeh , Roushangar Kiyoumars , Sihag Parveen
Published: March 2021

Sediment transportation and accurate estimation of its rate is a significant issue for river engineers and researchers. In this study, the capability of kernel based approaches including Kernel Extreme Learning Machine (KELM) and Gaussian Process Regression (GPR) was assessed for predicting the river daily Suspended Sediment Discharge (SSD). For this aim, the Mississippi River, with three consecutive hydrometric stations, was selected as the case study. Based on the sediment and flow characteristics during the period of 2005–2008, several models were developed and tested under two scenarios (i.e. modeling based on each station's own data or the previous stations' data). Two post-processing techniques, namely Wavelet Transform (WT) and Ensemble Empirical Mode Decomposition (EEMD), were used for enhancing the SSD modeling capability. Also, data post-proceeding was done using Simple Linear Averaging (SLAM) and Nonlinear Kernel Extreme Learning Machine Ensemble (NKELME) methods. Obtained results indicated that the integrated models resulted in more accurate outcomes. Data processing enhanced the models' capability up to 35%. It was found that SSD modeling based on the station's own data led to better results; however, using the integrated approaches, the previous station's data could be applied successfully for the SSD modeling when a station's own data were not available.
(Post-)Deuteronomistic Prohibition of Transvestitism (Deut 22:5)? The Question of Its Actual Meaning and Motivations
Authors: Lemański Janusz
Published: March 2021

Deut 22:5 marks the single instance of a prohibition of transvestitism in the Bible, and in its whole cultural milieu. The context in which it is situated suggests that it may have been inserted there as an addition, after the Babylonian captivity. That helps to narrow down the range of speculations as to the original Sitz im Leben of the law, and enables us to read it most of all within the canonical framework of the entirety of the Pentateuch. Hence, the precept pertains mainly to the principle of division of the human nature into the two sexes (Gen 1–2), the principle of retaining the order of creation (by not mixing kinds; Lev 19:19; Deut 22:9–11), and of keeping the procreational power, referred to here predominantly to masculinity (Gen 5:1–3; cf. Gen 1:28; 9:1.7).
The Paradox of Purity: Interpretation and Theological Implications of the Words καθαρός [katharos] and καθαρότης [katharotēs] in Wis 7:22–28
Authors: Krawczyk Mateusz
Published: March 2021

The double use of the word with the καθαρ root in the text of Wis 7:22–28 may set the interpretative direction for the discussion of the whole pericope. The exegesis of the pericope in the key of purity shows the following possibility of understanding the text: the moral aspect of purity of Wisdom can be imparted by it to pure people. A contradiction (paradox) in the text which concerns the subject of purity is observed: purity is, on the one hand, a condition, on the other, an effect of Wisdom’s imparting action. A look at the further context of pericope Wis 7:22–28 (in particular Wis 9 and Wis 10) can lead to a probable solution to this potential contradiction: it lies in the idea of being elected by God, which anticipates human action.
“Return to the Lord” (Hos 14:3): Repentance as the Essence of the Relationship Between God and Man
Authors: Pikor Wojciech
Published: March 2021

The article focuses on the theme of return/conversion in the Book of Hosea. The issue is presented from the perspective of the two parties of the covenant: God and Israel. At the starting point lies Israel’s refusal to return to God, and Yahweh’s threatening, punitive retribution to his people. The ending focuses on the conversion of the people to Yahweh, a development possible only owing to God’s preceding forgiveness, expressed by his turn to his people. These four different dynamics of return are reconstructed on the basis of the twenty-two instances of the verb šûb in the Book of Hosea.
Protein-Ligand Docking Simulations with AutoDock4 Focused on the Main Protease of SARS-CoV-2
Authors: de Azevedo Junior Walter Filgueira , Bitencourt-Ferreira Gabriela , Godoy Joana Retzke , Adriano Hilda Mayela Aran , dos Santos Bezerra Wallyson André , dos Santos Soares Alexandra Martins
Published: March 2021

Background:

The main protease of SARS-CoV-2 (Mpro) is one of the targets
identified in SARS-CoV-2, the causative agent of COVID-19. The application of X-ray
diffraction crystallography made available the three-dimensional structure of this protein
target in complex with ligands, which paved the way for docking studies.

Objective:

Our goal here is to review recent efforts in the application of docking simulations
to identify inhibitors of the Mpro using the program AutoDock4.

Methods:

We searched PubMed to identify studies that applied AutoDock4 for docking
against this protein target. We used the structures available for Mpro to analyze intermolecular
interactions and reviewed the methods used to search for inhibitors.

Results:

The application of docking against the structures available for the Mpro found ligands
with an estimated inhibition in the nanomolar range. Such computational approaches
focused on the crystal structures revealed potential inhibitors of Mpro that might exhibit
pharmacological activity against SARS-CoV-2. Nevertheless, most of these studies lack
the proper validation of the docking protocol. Also, they all ignored the potential use of
machine learning to predict affinity.

Conclusion:

The combination of structural data with computational approaches opened
the possibility to accelerate the search for drugs to treat COVID-19. Several studies used
AutoDock4 to search for inhibitors of Mpro. Most of them did not employ a validated
docking protocol, which lends support to critics of their computational methodology. Furthermore,
one of these studies reported the binding of chloroquine and hydroxychloroquine
to Mpro. This study ignores the scientific evidence against the use of these antimalarial
drugs to treat COVID-19.
Overview of PCTK3/CDK18: A Cyclin-Dependent Kinase Involved in Specific Functions in Post-Mitotic Cells
Authors: de Oliveira Pepino Rebeka , Coelho Fernanda , Janku Tatiane Aparecida Buzanello , Alencar Diandra Pinheiro , de Azevedo Walter Figueira , Canduri Fernanda
Published: March 2021

Cyclin-dependent kinases (CDKs) comprise a family of about 20 serine/threonine
kinases whose catalytic activity requires a regulatory subunit known as cyclin; these
enzymes play several roles in the cell cycle and transcription. PCTAIRE kinases (PCTKs)
are a CDK subfamily, characterized by serine to cysteine mutation in the consensus PSTAIRE
motif, involved in binding to the cyclin. One member of this class is PCTK3,
which has two isoforms (a and b) and is also known as CDK18. After being activated by
cyclin A2 or phosphorylation at Ser12 by PKA, PCTK3 can perform several functions.
Among these functions, we may highlight the following: modulation of cargo transport
in membrane traffic, p53-responsive gene, regulation of genome integrity. According to
different studies, PCTK3 dysfunction is related to a wide range of diseases, such as
metabolic diseases, cerebral ischemia, depression, cancer, neurological disorders, and
Alzheimer's disease. Although this protein participates in different biological events, we
may say that PCTK3 has received far less attention than other CDKs. There are thousands
of published articles about other CDKs and less than two hundred articles related
to PCTK3. The main objective of this review is to present the selected published studies
about this protein. Our focus is on PCTK3 particularities compared to other CDKs. Here
we give an overview of the biological functions of PCTK3 and explore its potential as a
target for drug design.

There are no curative strategies for ALS, and as a result the alternative therapies are gaining ground, in particular the stem cell-based therapies which hold a promising future. Here we describe an ALS patient, who by choice, received allogeneic human cord-blood derived multipotent stem cells (MSC) intravenously and intrathecally. This is the first snapshot of pre-and post-stem cell transplantation in an ALS patient through transcriptomic, epigenomic, and proteomic follow-up elucidating the effect of stem cells in ALS. Although new CSF proteins (FGA, B2M, FN1 and IGFBP3) were observed, but more work is needed to fully elucidate the effect based on larger cohorts in a clinical trial setting. These analyses may serve as a future guide to both scientists and clinicians alike in defining the utility of such cells in ALS treatment.
A Framework (SOCRATex) for Hierarchical Annotation of Unstructured Electronic Health Records and Integration Into a Standardized Medical Database: Development and Usability Study
Authors: Park Jimyung , You Seng Chan , Jeong Eugene , Weng Chunhua , Park Dongsu , Roh Jin , Lee Dong Yun , Cheong Jae Youn , Choi Jin Wook , Kang Mira , Park Rae Woong
Published: March 2021

Background

Although electronic health records (EHRs) have been widely used in secondary assessments, clinical documents are relatively less utilized owing to the lack of standardized clinical text frameworks across different institutions.

Objective

This study aimed to develop a framework for processing unstructured clinical documents of EHRs and integration with standardized structured data.

Methods

We developed a framework known as Staged Optimization of Curation, Regularization, and Annotation of clinical text (SOCRATex). SOCRATex has the following four aspects: (1) extracting clinical notes for the target population and preprocessing the data, (2) defining the annotation schema with a hierarchical structure, (3) performing document-level hierarchical annotation using the annotation schema, and (4) indexing annotations for a search engine system. To test the usability of the proposed framework, proof-of-concept studies were performed on EHRs. We defined three distinctive patient groups and extracted their clinical documents (ie, pathology reports, radiology reports, and admission notes). The documents were annotated and integrated into the Observational Medical Outcomes Partnership (OMOP)-common data model (CDM) database. The annotations were used for creating Cox proportional hazard models with different settings of clinical analyses to measure (1) all-cause mortality, (2) thyroid cancer recurrence, and (3) 30-day hospital readmission.

Results

Overall, 1055 clinical documents of 953 patients were extracted and annotated using the defined annotation schemas. The generated annotations were indexed into an unstructured textual data repository. Using the annotations of pathology reports, we identified that node metastasis and lymphovascular tumor invasion were associated with all-cause mortality among colon and rectum cancer patients (both P=.02). The other analyses involving measuring thyroid cancer recurrence using radiology reports and 30-day hospital readmission using admission notes in depressive disorder patients also showed results consistent with previous findings.

Conclusions

We propose a framework for hierarchical annotation of textual data and integration into a standardized OMOP-CDM medical database. The proof-of-concept studies demonstrated that our framework can effectively process and integrate diverse clinical documents with standardized structured data for clinical research.

Background

Public mass shootings are a significant public health problem that require ongoing systematic surveillance to test and inform policies that combat gun injuries. Although there is widespread agreement that something needs to be done to stop public mass shootings, opinions on exactly which policies that entails vary, such as the prohibition of assault weapons and large-capacity magazines.

Objective

The aim of this study was to determine if the Federal Assault Weapons Ban (FAWB) (1994-2004) reduced the number of public mass shootings while it was in place.

Methods

We extracted public mass shooting surveillance data from the Violence Project that matched our inclusion criteria of 4 or more fatalities in a public space during a single event. We performed regression discontinuity analysis, taking advantage of the imposition of the FAWB, which included a prohibition on large-capacity magazines in addition to assault weapons. We estimated a regression model of the 5-year moving average number of public mass shootings per year for the period of 1966 to 2019 controlling for population growth and homicides in general, introduced regression discontinuities in the intercept and a time trend for years coincident with the federal legislation (ie, 1994-2004), and also allowed for a differential effect of the homicide rate during this period. We introduced a second set of trend and intercept discontinuities for post-FAWB years to capture the effects of termination of the policy. We used the regression results to predict what would have happened from 1995 to 2019 had there been no FAWB and also to project what would have happened from 2005 onward had it remained in place.

Results

The FAWB resulted in a significant decrease in public mass shootings, number of gun deaths, and number of gun injuries. We estimate that the FAWB prevented 11 public mass shootings during the decade the ban was in place. A continuation of the FAWB would have prevented 30 public mass shootings that killed 339 people and injured an additional 1139 people.

Conclusions

This study demonstrates the utility of public health surveillance on gun violence. Surveillance informs policy on whether a ban on assault weapons and large-capacity magazines reduces public mass shootings. As society searches for effective policies to prevent the next mass shooting, we must consider the overwhelming evidence that bans on assault weapons and/or large-capacity magazines work.

Published: March 2021

Enhancement of crude protein content in rice bran with the solid‐state fermentation method in tray bioreactor using Rhizopus oryzae FNCC 6011 has been investigated. This research aimed to optimize the fermentation condition using the response surface methodology (RSM). The central composite design (CCD) with three independent variables, including substrate thickness (1 to 3 cm), fermentation temperature (28 to 32 °C), and nutrient concentration of KH2PO4 (2 to 6 g/L) used to determine the crude protein enrichment. The quadratic model has successfully described the effect of variable interactions on responses very well as indicated by the F value and p‐value are 11.20 and 0.0041, respectively. The multiple correlation coefficients (R2) of 0.9438 indicated that 94.38% of the model data has approached the actual data with a deviation of 5.62%. The interaction between the variable substrate thickness and the fermentation temperature is the most influential variable on the crude protein enrichment of rice bran, indicated by the highest F value of 24.08 and the lowest p‐value of 0.0027. The highest protein increase of 62.51% was obtained at 2 cm substrate thickness, fermentation temperature of 30 °C, and KH2PO4 concentration of 4 g/L.

Dengue virus (DENV) is the most geographically widespread arbovirus causing dengue disease epidemics in tropical and subtropical regions. Nature provides abundant plants as a source for lead molecules against various diseases including DENV infection. We investigated the antiviral effect of curcumin and 6‐gingerol, the major active constituent of turmeric (Curcuma longa Linn.) and ginger (Zingiber officinale Roscoe), respectively, against all four serotypes of DENV infecting human lung epithelial carcinoma (A549) cell line in vitro. Both compounds generated cell cytotoxicity to A549 cells at CC50 values of 108 µM for curcumin and 210 µM for 6‐gingerol. The compound curcumin showed antiviral properties as described by IC50 of 20.60, 13.95, 25.54, and 12.35 µM, while 6‐gingerol of 14.70, 14.17, 78.76, and 112.84 µM for DENV‐1, ‐2, ‐3, and ‐4, respectively. Different levels of antiviral properties were observed between DENV serotypes. Our findings suggest that the antiviral assay of compounds against DENV should be performed to all four serotypes and not limited to a particular serotype. In conclusion, curcumin and 6‐gingerol exhibit antiviral properties against DENV infection and could provide a new therapeutic approach for dengue disease treatment strategies.

Published: March 2021

The aim of the research was to examine and compare the effects of physical education (PE) classes with additional swimming training in relation to the regular teaching of PE on the motor abilities of students of a younger school age. A sample of 100 respondents was divided into two sub-samples in relation to the number of weekly exercises: a sub-sample of 50 students (control group-CG) with regular PE and a sub-sample of 50 students (experimental group-EG) who, besides their regular classes, had two additional weekly exercises in the form of swimming training. The training program of swimming courses was conducted for three months in the first semester of the 2015/2016 school year. Five standardized Eurofit battery tests were used to evaluate their motor abilities. The obtained results indicate that two additional weekly exercises in the form of swimming training caused statistically significant differences between the EG and the CG in long distance jogging, sit-ups for 30 s and a 20 m run test with a progressive increase in speed. The results suggest that swimming in addition to the already known impact on physiological characteristics positively influences the transformation of motor abilities in students of a younger school age.
TRAINING LOAD DEMANDS MEASURED BY SURFACE ELECTROMYOGRAPHY WEARABLE TECHNOLOGY WHEN PERFORMING LAW ENFORCEMENT-SPECIFIC BODY DRAGS
Authors: Lockie Robert George , Bloodgood Ashley , Moreno Matthew , McGuire Megan , Balfany Katherine , Dawes Jay
Published: March 2021

The use of surface electromyography (sEMG) wearable technology to measure training load (TL) during law enforcement-specific tasks (e.g. a body drag) requires investigation. This study determined muscle activation differences represented as TL during a 9.75-m drag with 74.84 kg and 90.72 kg dummies. Eight men and three women were fitted with a compression short or legging embedded with sEMG wearable technology to measure the quadriceps (QUAD; vastus medialis+vastus lateralis), biceps femoris (BF), and gluteus maximus (GM). After fitting on day one, participants completed maximal voluntary isometric contractions for each muscle to normalize the sEMG signal and calculate TL units. On days two and three, participants performed a 9.75 m body drag using either the 74.84 kg or the 90.72 kg dummy while wearing the technology. Participants lifted the dummy off the floor to a standing position and dragged it as quickly as possible over 9.75 m. Paired samples t-tests calculated between-drag differences for: time; QUAD, BF, GM, and total TL; and QUAD-BF, GM-BF, anterior-posterior (QUAD-GM+BF) ratios. QUAD TL was 9% greater (p=0.035), and GM TL was 8% lower (p=0.043), in the 90.72 kg body drag compared to the 74.84 kg drag. There were no between-mass differences in time, BF TL, total TL, or the ratios. QUAD TL increased while GM TL decreased when participants dragged a 90.72 kg dummy. As drag time was not different between the masses, drag mechanics may have changed leading to increased QUAD TL. sEMG wearable technology could be a useful method to measure TL in law enforcement-specific dragging tasks.

Published: March 2021

The stabilization of economic activity represents the basic purpose of macroeconomic policy. In the last few years, the achievement of price stability, or the relatively low and stable inflation rate, has been imposed as the policy’s main goal, in accordance with the recommendations of the so-called New consensus macroeconomics. In line with that, the identification of variables, which determine the inflation rate and cause its changes, is crucial. From its occurrence, the relationship of the Phillips curve provided an explanation of the inflation dynamics based on the movement of different factors, depending on the variant of the curve observed. Hence, the subject of the paper is the presentation and evaluation of the contemporary concepts of the Phillips curve in the context of the application of the efficient stabilization policy. The main objective of the paper is to reconsider the concept’s validity, especially in the conditions of serious economic disorders, such as the Great Recession. The applied analysis indicates that the dominant New Keynesian concept of the Phillips curve can serve for the successful conducting of economic policy, if it is supplemented with the variables of fiscal policy and financial stability policy.
THE CHARACTERISTICS OF CULTURAL CONSUMPTION OF THE POPULATION OF THE CITY OF NIŠ
Authors: Petković Jelena
Published: March 2021

The paper is based on the results of an extensive empirical study of the cultural participation of the urban, suburban and rural population of the City of Niš, carried out in 2015, using a combined questionnaire on a sample of 800 respondents. The research results presented here refer only to the aspect of cultural consumption, with the aim of presenting the empirical findings and indicating whether, and to what extent, the place of residence of the participants, in correlation with the remaining socio-demographic features (age, gender, level of education, profession, satisfaction with one’s financial status), influence their cultural consumption, determining the frequency, forms and limitations of this consumption. The research approach is primarily founded in sociology, and is methodologically quantitatively focused on and developed within the theory of the class-cultural homology of Pierre Bourdieu. The research results indicate that young people who live in urban settlements, with a higher education background and favorable economic means, more often than others participate in cultural consumption, and are more frequently than others involved in acquiring additional artistic, intellectual and/or technical knowledge or skills in their leisure time. One half of all the respondents included in the study, mostly the middle-aged (40–54 years of age), point out the lack of money (an objective obstacle), while one-fourth of all the surveyed respondents, especially the oldest members of village societies (over the age of 55), point out the lack of interest (a subjective obstacle) as the main limitation to their own cultural consumption. The results mostly indicate an average frequency and very limited extent of cultural consumption of all the respondents included in the research to residential inequality and the social predispositions of cultural practices.

Published: March 2021

In the context of a very turbulent environment where various challenges are more and more present, companies often apply different strategies in order to harmonize their business with new and often unfavorable conditions. One of the possible strategies of companies is the downsizing strategy. Downsizing, as an organizational strategy, usually involves a reorganization that can be implemented in different ways, but in which the resulting outcome often causes a reduced number of employees. Research around the world has highlighted the various effects of this strategy on the performance of organizations. On the one hand, cost are reduced as it strives to increase profitability and productivity. On the other hand, various problems often arise in the form of attitudes and behavior of employees, reflected in the changed quality of service that is provided, employee satisfaction, their loyalty and willingness to leave the company. The aim of this paper is to explore the relation between the application of different approaches to the downsizing strategy in organizations and the perceived service quality. The survey was carried out on a sample of 160 companies in Serbia, based on the data collected during the Cranet project, from 2015 to 2016. The methodology used during the research included research of the available literature and results of previous studies, as well as the application of statistical techniques for data analysis, factor analysis, Spearman’s correlation and hierarchical linear regression. The results of the research indicate that there is a negative link between the observed variables, that is, the implementation of the downsizing in certain forms is associated with a lower level of the perceived quality of service.

The authors of this paper address the problem of education which in its transformation, when small countries are concerned, means openness towards the uncritical acceptance of Anglo-Saxon educational and cultural norms. Western society, with its economic supremacy and political aspirations, has managed to include contemporaries into the process of transformation, which among other things involves uniformity of education and culture. This enables it to maintain that supremacy. The authors emphasize the difference between internationalization and globalization of education. Special attention is given to the Bologna process in terms of the neoliberal integration strategy which essentially involves the neglect of national identity. They criticize the ongoing commercialization of education and in this sense the marginalization of science in society, which further leads to decadence. Ethical goals are being neglected on account of abstract individualism.

Entre el biznes y el arte: el sistema de estrellas y el teatro empresarial en el circuito teatral judío de Buenos Aires
Authors: Ansaldo Paula
Published: March 2021

En 1930 comenzó en Buenos Aires la época dorada del teatro judío en Argentina. Sin embargo, ya desde las primeras décadas del siglo XX, el desarrollo del circuito teatral en ídish (yidis) se organizó en función de un sistema de estrellas por el cual los empresarios traían a importantes figuras del exterior que, con su fama y prestigio, despertaban el interés de las masas judías porteñas y les garantizaban un éxito seguro de la temporada. Para algunos, la visita de las estrellas era lo que permitía la supervivencia y el crecimiento del teatro judío en Buenos Aires, para otros, era la responsable de que no se pudiera desarrollar un teatro judío-argentino que fuera impulsado por artistas locales. En este trabajo indagaremos en los debates y cuestionamientos que se generaron en torno al “star system”, así como en el modo de funcionamiento del teatro empresarial judío.
Marcas de cantería en la iglesia Matriz de Moquegua, Perú

Published: March 2021

La práctica de “firmar” los sillares mediante signos identificadores es muy antigua; fue muy común, sobre todo en la Europa medieval, de donde se trasplantó a América. El muro superviviente de la iglesia matriz de Moquegua —muchas veces destruida por sismos y erupciones hasta su abandono total en 1868— contiene la mayor concentración conocida de signos de cantero del Perú. Se han reconocido 107 tipos de signos alfabéticos, geométricos y figurativos grabados posiblemente entre 1784 y 1792 y que se caracterizan por su gran talla y la tosquedad de su trazo. Existen por lo menos dos tipos de ejemplares singulares de carácter figurativo que quizá no correspondan a marcas lapicidas, sino que podrían considerarse como litograbados. El artículo contiene, además, un repaso sobre el origen de las marcas de cantero y los estudios precursores sobre ellas.

Bacterial contamination is hard to avoid during dental implant surgery. Macrophages and their polarisation play a decisive role in bacterial colonisation and tissue integration on bacterially contaminated dental implants. The present study investigated the role of macrophages in stimulating tissue coverage overgrowth of contaminating oral bacteria on polished titanium (Ti-P) and acid-etched zirconium dioxide (ZrO2-MA) dental implant materials. Different co-culture models were employed to determine phagocytosis rates of Streptococcus mitis or Staphylococcus aureus contaminating a dental implant surface and the influence of contaminating bacteria and osteoblasts (U2OS) on macrophage polarisation. S. aureus was phagocytized in higher numbers than S. mitis in bi-cultures on smooth Ti-P surfaces. Contaminating S. mitis stimulated near full polarisation of macrophages from a non-Ym1-expressing- to a Ym1-expressing-phenotype on smooth Ti-P, but on ZrO2-MA both phenotypes occurred. In tri-cultures with U2OS-cells on smooth Ti-P, a larger percentage of macrophages remained in their non-Ym1-expressing, “fighting” M1-like phenotype to clear Ti-P surfaces from contaminating bacteria. On ZrO2-MA surfaces, more macrophages tended towards their “fix- and-repair” M2-like phenotype than on Ti-P surfaces. Surface coverage of smooth, bacterially contaminated Ti-P surfaces by U2OS-cells was more effectively stimulated by fighting, M1-like macrophages than on ZrO2-MA surfaces. Comprehensive guidelines are provided for the development of infection-resistant, dental implant materials, including bacteria, tissue and immune cells. These guidelines point to more promising results for clinical application of Ti-P as compared with ZrO2-MA.

Dendrocalamus longispathus Kurz clumps located in Mamit District, Mizoram, India was observed to study the quality and quantity of seed produced during the sporadic flowering as an ecological indicator for further flowering precaution in Mizoram. Soil seed bank and seed drop quantity of seeds in a culm were estimted for further afforestation of D. longispathus in a barren or wasteland lands in tropical sloppy mountainous conditions. The study would be applicable in reforestation, programme by dispersing the collected seeds into a forest areas decreasing in numbers of D. longispathus. The study between the disturbed site and undisturbed site compared to understand the difference between the two sites in terms of their seed quantity, seed drop, seed viability and soil seed bank. The number of seed produced by a flowering D. longispathus culm was higher in undisturbed bamboo forest. Seed viability test using tissue paper test indicated that there was 50.5% and 55.7% viability for disturbed and undisturbed sites respectively. However, using 1% solution of 2, 3, 5-triphenyltetrazolium chloride from a disturbed and undisturbed sitess showed 52.2 % and 56 % viability respectively. Adoption of scientific management techniques advocated for both bamboo plantations and natural bamboo forests to improve the quality and growing stock volume of bamboo in Mizoram.

A survey was conducted to study the fruit characters of jackfruits grown in West Garo Hills of Meghalaya during 2016 to 2018. More than 50 jackfruit trees bearing 15 to 40 years of age were initially evaluated, out of which 10 accessions exhibiting distinct morphological characters were selected for detailed characterization. Significant variations were observed in terms of qualitative and quantitative parameters of fruit under the study. Jackfruit accession viz. WGHJ-1 exhibited desirable characters such as big sized flakes, big and heavy seeds, high fruit:rind ratio, flake:fruit ratio, juicy pulp etc. hence it is considered ideal for making processed products like jam, jelly, halwa, candy, juice etc. as well as for starch extraction from seeds. Considering the small sized fruit with flat spines, thin rind, high flake: fruit ratio, highest number of thick and sweet flakes, accession WGHJ-5 is recommended for table purpose. The sweet, thick, heavy and non-juicy flake makes WGHJ-8 a probable good type for chips making and table purpose. This paper presents 41 characteristic features related to the whole fruit, flakes and seeds of 10 jackfruit accessions selected from the West Garo Hills of Meghalaya.

Via this look at efforts have been made to increase a chain of latest donor-acceptor (D-A) systems through the usage of 4-methoxy-2,7,nine-trimethyl-9H-carbazole (2,7-MMCB) as a electron donor and benzo[c][1,2,5] oxadiazole (BCO); benzo[c] [1,2,5] thiadiazole (BCT); benzo[c][1,2,5]selenadiazole (BCS); [1,2,5]oxadiazolo[3,4-c]pyridine (OCP); [1,2,5] thiadiazolo [3,4-c]pyridine (TCP); [1,2,5] selenadiazolo [3,4-c]pyridine (SCP); [1,2,5] oxadiazolo[3,4-d]pyridazine (ODP); [1,2,5] thiadiazolo[3,4-d]pyridazine (TDP) as electron acceptors. In this work, we executed calculations of DFT and TD-DFT/B3LYPmethod with /6-31G basis. Calculated and explored theoretical expertise of the HOMO, LUMO oenergies, the band gap (Eg), and the open-circuit voltage (Voc) of the studied compounds. To take a look at the relationship between molecularstructure and optoelectronic properties, the consequences of the extraordinary acceptor effect on the geometries and optoelectronic residences of those substances were discussed. The outcomes acquired show how the digital residences can be modified with many lessons of acceptors through the substituent and suggest that 2,7MMCB-ODP, 2,7MM CB-TDP, and 2,7MM CB-SDP are these compounds as suitable candidates for optoelectronic packages in solar cells inclusive of BHJ.
