Scientific creativity and responsibility are among the main competencies in the society 5.0, but they are not trained in school. Therefore, this study wants to produce a valid Creative Responsibility Based Learning (CRBL) to prepare students for society 5.0. This research is part of the educational research design using the Tessmer model, but data collection is still at the stage of self-evaluation and expert validation. CRBL's instructional goals are science process skills, responsibility, and scientific creativity; and other impact is the competence of society 5.0. The design of CRBL phase includes: generating creative responsibility, organizing creative learning needs, guiding group investigations, actualizing creative responsibilities, evaluating and reflecting. Students can explore creative and imaginative ideas, design creative products, and create technology products. In addition, the three validators agreed that CRBL was valid to prepare them for society 5.0.
Automatic discovery of chemical reactions using imposed activation
Authors: Lavigne Cyrille , dos Passos Gomes Gabriel , Pollice Robert , Aspuru-Guzik Alan
Published: September 2020

Computational power and quantum chemical methods have improved immensely since computers were first applied to the study of reactivity, but the de novo prediction of chemical reactions has remained challenging. We show that complex reactions can be efficiently and autonomously predicted using chemical activation imposed by simple geometrical constraints. Our approach is demonstrated on realistic and challenging chemistry, such as a triple cyclization cascade involved in the total synthesis of a natural product and several oxidative addition reactions of complex drug-like molecules. Notably and in contrast with traditional hand-guided computational chemistry calculations, our method requires minimal human involvement and no prior knowledge of products or mechanisms. Imposed activation can be a transformational tool to screen for chemical reactivity and mechanisms as well as to study byproduct formation and decomposition.

Conjugation of the transitionstate-cation analogue DANA to polymeric scaffolds led to highly potent inhibitors of bacterial sialidases. Each clustered DANA on the polymers saw its inhibitory potency for S. pneumoniae or B. thetaiotaomicron sialidases improved by more than four orders of magnitude. This extends the multivalent concept to this important class of enzymes.
Motivational and Demotivational Factors Affecting a Teacher’s Decision on Whether to Do Research
Authors: Šorgo Andrej , Heric Jasmina
Published: September 2020

One of the teacher’s basic tasks should be to ensure that the quality of his/her educational work is continually enhanced by the application of practitioner research, as a recognised genre of educational research. The aim of this study was to explore factors that can motivate or demotivate teachers to include research in their educational practice. An online questionnaire was addressed to all Slovenian primary and secondary school teachers and full responses were received from 325 teachers. Although the teachers expressed high perceived self-confidence in their research abilities, this did not transfer to research activity, as only about one quarter of the respondents reported that they performed research. The main drivers of research are an intrinsic motivation for research and career goal orientation, followed by the relatively low influence of important others. Practitioner research is highly valued among teachers, so there must be other factors at work preventing more teachers from starting research activities. Among the leading factors recognised as obstacles are those that can be regarded as facilitating conditions in terms of motivational theory. Work overload, lack of time, school bureaucracy and family life can be regarded as competing with research for the teacher’s time, along with other important issues. The school climate cannot be regarded as the main obstacle to research. The findings call for the reallocation of at least some work duties in favour of research as part of regular employment.

Authors: Nurmalasari Anggi , Maharani Shinta
Published: September 2020

Single-cell protein (SCP) is the term used for crude or pure protein derived from simple single or multi-celled microorganisms. Pineapple peel contains monosaccharides as much as 10.8% so that it can be used as a fermentation medium in single-cell protein production. The purpose of this study was to determine the effect of adding carbon sources of fructose and sucrose on pH, cell dry weight, and protein content in the manufacture of single-cell proteins. This study used a completely randomized design (CRD) with two factors, namely the addition of carbon (fructose, sucrose, and control) and fermentation time (24.48, and 72 hours). The data analysis used the variance test and the Duncan Multiple Range Test (DMRT) continued to test with a confidence level of 95%. The results showed that the addition of carbon to the media had a very significant effect on media pH, cell dry weight, and protein content. In the medium with the addition of fructose it has a pH of 3.81; dry weight 0.4203 grams; and protein content 69.08/L. Whereas in the media with the addition of sucrose, the pH was 4.33, the dry weight of the cells was 0.3385 grams, and the cells had a protein content of 85.55 mg/L. The addition of a fructose carbon source gave the cell dry weight more than the addition of carbon sucrose

Published: September 2020

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from December 2017 through May 2018 to study the effect of rice residue on weed suppression and yield of boro rice. The experiment consisted of four different rice residue treatments such as no rice residue, 2.5, 5 and 7.5t ha-1rice residue, and five different herbicidal treatments such as no herbicide (H0), 25% of the recommended dose (RD), 50% RD, 75% RD and 100% of RD. The experiment was laid out in a randomized complete block design with three replications. Seven weed species belonging to five families infested the experimental plots. Weed density and weed dry weight were significantly affected by incorporation of rice residue and herbicidal treatment. The maximum weed growth was noticed with no rice residue incorporation and application of no herbicide. The minimum weed density and dry weight were found in incorporation of 5 t rice residue ha-1 and application of 100% of RD of herbicide treatment. Rice residue exerted significant effect on yield and yield contributing characters like plant height, number of total tillers hill-1, number of effective tillers hill-1 and grain yield. The highest grain yield (4.89 t ha-1) was recorded with the incorporation of 2.5 t ha-1 rice residue which was statistically identical with5 and 7.5 t ha-1 rice residues. The grain yield (5.70 t ha-1) produced by 75% of RD of herbicide was the highest among the other herbicidal treatments. The highest number of effective tillers hill-1 (12.80), 1000-grain weight (21.07), grain yield (5.87 t ha-1) and straw yield (7.21 t ha-1) were observed with the incorporation of 5 t rice residue ha-1 and 75% of the RD of herbicide treatment. Results of this study indicate that rice residue showed potentiality to inhibit the growth of weed and exerted significant effect on the yield of boro rice. Rice residue @ 5 t ha-1 with application of herbicide of 75% RD might be suggested to use for effective weed management and better grain yield of boro rice.

Published: September 2020

Two field studies were conducted consecutively in the summer season of 2015 and 2016 to investigate the effect of different soil mulching materials (bare soil: BS as a control, white plastic: WP, black plastic: BP and rice straw: RS) on growth, productivity, and water-use efficiency (WUE) of potato under three levels of irrigation (I100=100%, I80=80%, and I60=70% of crop evapotranspiration). Growth characteristics, yield and its components, and WUE were significantly (P ≤ 0.05) affected by both irrigation level and mulching materials. All mulching materials effectively enhanced growth and productivity when compared to bare soil. Potato plants grown under BP and WP as well as RS showed higher mean values of large size (> 60 mm) tubers and WUE compared to non-mulched treatment (BS) in both seasons. Mulching treatments noticeably increased tuber yield in the order of BP > RS > WP. Results displayed that, under different soil mulching materials, the I80 strategy studied here could be successfully applied during summer season in commercial potato production allowing water savings of 20% without any detrimental effect on plant growth or productivity.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to study the effect of integrated fertilizer and weed management on the growth performance of aromatic Boro rice (cv. BRRI dhan50). The experiment comprised six fertilizer managements viz., control (no manures and no fertilizers), recommended dose of inorganic fertilizers (i.e. Urea, TSP, MoP, Gypsum, ZnSO4 @ 250, 120, 120, 100, 10 kg ha-1, respectively), 50% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 75% of recommended dose of inorganic fertilizers + cowdung @ 5 t ha-1, 50% of recommended dose of inorganic fertilizers + poultry manure @ 2.5 t ha-1, and 75% of recommended dose of inorganic fertilizers +  poultry manure @ 2.5 t ha-1 and four weed managements viz., control (no weeding), pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + one hand weeding at 35 DAT, post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1 + one hand weeding at 35 DAT, pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1. The experiment was laid out in a factorial randomized complete block design with three replications. Growth traits of aromatic Boro rice (cv. BRRI dhan50) were significantly influenced by integrated fertilizer and weed management. Plant height, number of tillers hill-1, total dry matter, leaf area index (LAI) and crop growth rate (CGR) gave their highest values in 75% of recommended dose of inorganic fertilizers and poultry manure @ 2.5 t ha-1 along with pre-emergence herbicide, Panida 33 EC @ 2.5 l ha-1 + post-emergence herbicide, Granite 240 SC @ 93.70 ml ha-1 while their corresponding lowest values were found in control. So it can be concluded that, the interaction of 75% of recommended dose of inorganic fertilizers and poultry manure @ 2.5 t ha-1 along with pre-emergence herbicide (Panida 33 EC @ 2.5 l ha-1) + post-emergence herbicide (Granite 240 SC @ 93.70 ml ha-1) appears as the promising combination in respect of growth performance of aromatic Boro rice (cv. BRRI dhan50).

Aflatoxin contamination, particularly common in cultured fishes in Asian countries, are considered unsafe both for fish and human health. However, the presence of aflatoxin in cultured fish feed and their effect are still under estimated in Bangladesh. The present study aimed to assess the effects of aflatoxin on growth performance and residues in tilapia (Oreochromis niloticus) fingerlings. Fish feed were treated with several concentration of aflatoxin as 0 ppb (T0, control), 25 ppb (T1), 50 ppb (T2) and 100 ppb (T3) and fed the tilapia fingerlings (n=10) in individual glass aquaria (24×12×12 inch, 105-litre capacity) conditions for 12 weeks. Comparatively higher body length (cm) and weight gain (g) were observed in treatment T0 (1.68 and 4.98) and T1 (1.60 and 5.48) than those of treatment T2 (1.31 and 4.06) and T3 (1.20 and 3.10), respectively. The specific growth rate (SGR) were almost similar in treatment T0 (52%), T1 (51%) and T2 (52%) whereas declined significantly (p<0.05) in T3 (39%). Higher survival rate was also demonstrated in treatment T0 (90%) and T1 (90%) whereas significantly decreased in treatment T2 (60%) and T3 (40%). The residue of aflatoxin was not detected in T0 and T1. On the contrary, the residual effect in tilapia fingerling was evident in T2 and T3 treatment. The findings of the present study revealed that aflatoxin contaminated feed is harmful for the growth performance and survival of O. niloticus fingerlings. Further study is necessary to safeguard the aquaculture production as well as to produce healthy food for human consumption.

In order to efficiently work out in advanced plant metabolic pathway engineering techniques, a detailed knowledge and expertise is essentially needed regarding the plant cell physiology and the mechanics of plant metabolism. Mathematical and statistical models to scale and map the genome for integrative metabolic pathway activity, signal transduction mechanism in the genome, gene regulation and the networks of protein-protein interaction can provide the in-depth knowledge to work efficiently on plant metabolic pathway engineering studies. Incorporation of omics data into these statistical and mathematical models is crucial in the case of drug discovery using the plant system. Recently, artificial intelligence concept and approaches are experimentally applied for efficient and accurate metabolic engineering in plants.

Maintenance  is  a  very  important  thing  to  do  in  order  to  keep  the  aircraft  in flightworthiness. One form of maintenance activity is the replacement of components that have been damaged (failed). Inventory components can not be a avided because to get it can not be done  suddenly  while  for  those  needs  can  occur  suddenly.  Thus,  it  is  necessary  to  plan  the number  of  component  inventories  so  that  smooth  production  is  maintained.  Efforts  to  solve these problems use the Mean Time Between Removal (MTBR) equation. Where MTBR is used to determine inventory levels and component replacement scheduling. In addition, the MTBR is a formula or model to determine how much inventory per year will minimize the depletion of  inventory  in  the depository  and  for  estimating  component  replacement.  From  the  data processingof the G120 TP-A GROB, the number of component inventories in one year is based on  the  age  of  components  from  manufacture (MTBRStandard),  among  others:  10  Beta  Valve Components, 17 Bleed Valve Components, and 13 Propeller Reduction Gearbox Components
