Bengkulu Province has many local rice germplasms that have adapted to specific areas. The germplasm has certain character advantages so that it is maintained by farmers. The characteristics of each germplasm need to be identified in order to improve the properties of the existing germplasm. This study aimed to determine the performance, to estimate the value of genetic parameters, and to determine the genetic relationship of local rice genotypes collected from four districts in Bengkulu Province. The results showed that the ‘Kuning Sulaowangi’ genotype was the earliest in maturity had the highest number of tillers amongst genotypes. Genotypes which have significantly the highest average component yields were ‘Kunig Air Dingin’ and ‘Impera’. Traits that have a high heritability estimated value were weight of 100 grains (91.046%) and grain weight per panicle (80.252%). The weight of 100 grains also has the highest genetic variability value. Thus increasing local rice production is possible. Based on the results of the analysis with the similarity coefficient of 55%, the local rice genotypes could be grouped into two groups. Group I consisted of 9 genotypes namely ‘Kuning Pendek’, ‘Humbur’, ‘Cantik’, ‘Pandak Kelabu’, ‘Cisadane Putih’, ‘Kuning Sulaowangi’, ‘China Abang’, ‘China Putih’ and ‘Impera’. Other genotypes were in Group II. Trait improvement can be done through hybridization between individuals of different groups. To develope early in maturity and high-yielding varieties can be done through hybridization of the ‘Kunig Sulaowangi’ and ‘Kunig Air Dingin’

ABSTRACTFinding the appropriate method of fertilizer application to simultaneously enhance farm productivity and ensure ecosystem sustainability has been receiving a lot of attention. A field experiment was carried in the Research Plot Agriculture Faculty Bengkulu University Campus Indonesia in 2017. The purpose of this study was (1) to assess the significant effects of inorganic N fertilizer (IF) substitution with bio-fortified compost (BC) under equal N conditions on growth, N accumulation, and yield of sweet corn, and (2) to determine the appropriate level to which inorganic N fertilizer could be reduced and equivalently replaced by bio-fortified compost to promote sweet corn growth and yield. The treatments consisted of six different proportions of inorganic N fertilizer (IF) substitution with bio-fortified compost (BC). Each treatment was designed on the basis of equal amount of total N input from a combination of both fertilizers (138 kg N ha-1). They were arranged in a randomized block design with 3 replications. They included (1) 100% IF plus 0% BC, (2) 75% IF plus 25% BC, (3) 50% IF plus 50% BC, (4) 25% IF plus 75%, (5) 0% IF plus 100% BC, and (6) no IF and no BC. The results showed that the increasing proportion of IF replaced by BC resulted in an increase for all variables (except for plant height) but they decreased when 100% IF substitution with 100% BC was applied. Among the partial substitution treatments, 50% IF plus 50% BC consistently produced the best growth, N accumulation, and yield increase. Treatments of 50% IF plus 50% BC and 25% IF plus 75% BC produced the highest green cob weight with husk per plot (10.74 – 10.84 kg plot-1), which was 16% to 19% higher than treatment of 100% IF plus % BC. The three partial substitution treatments produced crop yield components as good as treatment of 100% IF plus 0% BC. Treatment of 0% IF plus 100% BC reduced plant growth, N accumulation, and crop yield and its components. The appropriate level to which IF could be reduced and equivalently replaced by BC was at the range of 25% to 75%. Hence, a suitable replacement of inorganic N fertilizer with bio-fortified compost is considered a reasoned way to simultaneously increase crop yield and reduce environmental degradation.Keywords: organic fertilizer, chemical fertilizer, bio-fortification, chemical fertilizer substitution, bio-fortified compost

Published: January 2020

Introduction: Lung ultrasonography (LUS) is a useful diagnostic tool in critical care setting. Lung ultrasound at bed side is relatively easy to perform, cost effective and reproducible. Analysis of various sign and profile, alone or in combination is as accurate as gold standard test like Computed Tomography scan of the chest in detection of etiology of acute respiratory failure. The aim of our study was to perform bed side lung ultrasound in patent with ARF and to find out the diagnostic accuracy of lung ultrasound when compared with diagnosis made by the clinician.
Methods: This descriptive observational study was conducted at tertiary care teaching centre in Nepal between February 2019 and July 2019. Consecutive samples of acute respiratory failure patient were included. Lung ultrasound was performed at bed side by fellows of pulmonary critical care medicine. Specific 10 signs of blue protocol were assessed in six different sites of both the chest. Findings of LUS was recorded and analysed to formulate a diagnosis, and finally compared with the final diagnosis.
Results: Forty eight patients of acute respiratory failure with median age of 66 years (17 to 89 years) were included with 66.7% being females. 97.9 % of the patient presented with acute shortness of breath of less than one week duration. A total of 13 different diagnosis was made at the end of the treatment for all the patient. LUS accurately diagnosed them in 43 cases, with an overall accuracy of 89.6 %. Chronic obstructive pulmonary disease, pulmonary edema, pneumonia, pleural effusion, pneumothorax were accurately diagnosed with LUS however in acute respiratory distress syndrome and interstitial lung disease, lung ultrasound had poor diagnostic accuracy.
Conclusions: Lung ultrasound is useful tool in diagnosing etiology of acute respiratory failure. Diagnosis made by lung ultrasound was 89.6% correct when compared with final diagnosis made by clinician.

Published: January 2020

Abstract
Mixtu res of the anionic surfactant AEC7-Na (branched alcohol ether carboxylate) and the cationic surfactant didecylmethylhydroxyethylammonium chloride (DEQ) were systematically investigated. The results showed that the mixtures possess synergisms. The DEQ-AEC7-Na mixture with a mass ratio of 1:1 showed the best result in terms of surface activity, wettability and emulsifying performance. However, when the mass ratio m(DEQ):m(AEC7-Na) = 8:2, the foaming ability and foam stability of the individual surfactants are better. Vesicles smaller than 100 nm coexist with worm-like micelles as soon as a small amount of AEC7- Na is added to DEQ (m(DEQ):m(AEC7-Na) = 8:2). At m(DEQ):m(AEC7-Na) = 4:6 and 2:8, vesicles of approximate ly 80 nm were observed.

Abstract
The paper presents a system-based approach for predicting the changes of the plasma concentration and the therapeutic effect of sodium p-aminosalicylate caused by addition of surfactant Tween 80 to a liquid dosage form. A predictive pharmacokinetic model of the oral administration is synthetized together with the corresponding model of its parametric sensitivity. The sensitivities predicted by the model are then compared to those obtained from the in-vi vo experiment. The close correspondence between them is used to prove the model correctness. Similarly the Emax model of the therapeutic effect predicts influences of the added surfactants on the therapeutic effect. In this context, the problem of determining an optimal absorption rate for the desired time course of the therapeutic effect is solved. As a by-product this study, it is shown that the (in-silico generated) sensitivity of plasma concentration to the drug absorption rate may provide information on how far the in-silico experiment can serve as a substitute for in-vivo bioavailability and bioequivalence studies

Published: January 2020

Abstract
Herein, synthesis of rhamnolipid surfactants was performed using a non-pathogenic Pseudomona s putida strain cultured on a variety of waste frying oils (WFOs) under Taguchi multi-objective optimization design. The effect of substrate types, fermentation setups and incubation time on the biomass concentration, rhamnolipid yield and surface tension of the cultivate media has been investigated. The results demonstrate that the multi-objectives investigation helps to document the optimal limits of the process parameters based on Gray relational analysis. After finding the optimal conditions, a validati on run was performed; therein, the rhamnolipid yield increased from 3.4 to 4.1 g/L; the biomass concentration decreased by 4.84% with an additional surface tension reduction of 2.19% due to an increase of rhamnolipids yield. Overall, soybean WFO was observed to be a preferred substrate for P. putida strain both under Taguchi design and the validation run. The present study proposes a low total of runs and optimum product yield under the Taguchi based multi-objective optimization.

Abstract
Cationic quaternary ammonium surfactant s are widely applied in many fields, such as detergent, cosmetics, petroleum and natural gas industries. However, the study of the effect of anion on cationic surfactants is rare. To research the influence of anions on the surface properties, a cationic surfactant was prepared, (cetyltrimethyl ammonium isonicotinate, CTAIN), and the surface properties were studied, including surface tension, critical micelle concentration, foaming ability and stability, and corrosion inhibition. The results indicated that the minimum surface tension of CTAIN is lower than that of CTAC, the foaming ability and foaming stability of CTAIN is higher than that of CTAC, and the corrosion inhibition efficiency on mild steel of CTAC is more potent than that of CTAIN. All the results indicate that the new cationic quaternary ammonium surfactant is a useful surfactant in the related fields.
Niepotrzebna formalność czy brak zaangażowania – jak postrzegane są motywy par, które nie decydują się na związek małżeński?
Authors: Mynarska Monika 
Published: January 2020

Although cohabitation is increasingly common in Poland, it is usually considered a transitional, testing stage that leads to marriage, which constitutes the preferred form of family life in the country. Does it mean that couples who do not choose to marry are perceived as somewhat “worse” than those tying the knot? Using qualitative data from focus group interviews with 69 men and women aged 25–40, I aimed to answer the following questions: What are social perceptions of couples who have already “tested” their relationship, but still live together and refrain from marriage? In particular, what are the motives attributed to such couples and how – if at all – these motives are linked to the quality of the relationships?
There were four themes related to such motives identified in the analysed material: (1) the perception of marriage as an unnecessary expense that does not change anything in a relationship, or even makes things worse; (2) fear of an ultimate commitment; (3) uncertainty whether this is the right partner and the resulting low level of commitment in the relationship; (4) rejection of traditional gender roles. Commitment appears central in the analysed discussions suggesting that this concept should constitute an important topic in future studies on unions in Poland.

Published: January 2020

The article presents an assessment of the methodological state of introduction of psychotechnology of formation of moral stability of schoolchildren in conditions of a fragile society. The author confirms the lack of a coherent theoretically validated and empirically proven concept in the psychological science of purposeful development of the moral and psychological stability of modern youth, considering the genetically modeling approach. Insufficiency of thorough psychological researches of the problem of moral and psychological stability of youth in conditions of a fragile society hinders the development and introduction into the educational process of productive socio-cultural and psychological and pedagogical technologies.
It is noted that it is necessary to take into account that purposeful military-patriotic activity promotes moral development of the personality of schoolchildren and cadets, influences in a certain way the formation of their individual qualities, patriotic feelings and beliefs, which awakens active actions and actions. In view of this, in the process of military-patriotic education in pre-conscript youth it is necessary to form a high patriotic consciousness, to train skillfully to act under different emotional states, to develop practical skills, habits and habits to prepare oneself for activity in adverse and even extreme conditions.
