Published: March 2021

The main goal of the research was to explore the existence of phytochemicals, quantification of primary and secondary metabolites of leaves extract of Artabotrys hexapetalus (L.f.) Bhandari. The phytochemical activity of leaves of Artabotrys hexapetalus was assessed using different solvent extracts like water, ethanol, acetone, chloroform and petroleum ether. Among the different solvent extracts, aqueous leaves extract revealed the high content of phytochemicals. So the aqueous leaves extract was used for further investigations. Aqueous leaves extract of Artabotrys hexapetalus was subjected to quantitative analysis of primary metabolites like carbohydrates, proteins and amino acids. Quantitative analysis of secondary metabolites like flavonoids, tannins and phenols were performed using aqueous leaves extract of Artabotrys hexapetalus. Qualitative screening of phytochemicals reported the existence of carbohydrates, amino acids, proteins, flavonoids, alkaloids, saponins, phenols, glycosides, tannins and diterpenes. Quantitative analysis showed the presence of carbohydrates (43.16±1.0 mg/g extract), proteins (60.4±0.88 mg/g extract), amino acids (19.33 ± 1.30 mg/g extract), flavonoids (28.3 ±0.91 mg/g extract), tannins (24.53±1.02 mg/g extract) and phenols (7.63±0.85 mg/g extract). The present study concluded that aqueous leaves extract of Artabotrys hexapetalus as a potential source of phytochemicals, primary and secondary metabolites.

The aim of this research is to compare alternative inoculant source for in vitro rumen fermentation. In the first experiment, inoculant from fistulated cattle kept in LIPI and IPB (Fis1 and Fis2) and inoculant from Bogor municipality abattoir and IPB abattoir (Abo1 and Abo2) were tested for their pH, total bacterial count, and protozoal number using a complete block design with four replications. In the second experiment, the effect of the inoculant sources was tested on cornmeal (F1), soybean oil meal (F2), Napier grass (F3), and dairy cattle complete ration (F4) fermentability and digestibility including pH, VFA, NH3, IVDMD and IVOMD parameters. The results showed an unsignificant different protozoal number among inoculant sources. The pH of Fis2 rumen liquor was significantly lower (p<0.05) than others. The bacterial population was significantly higher (p<0.05) in Fis2 and Abo2 than Abo1, and Fis1. The inoculant pH after feed fermentability was not influenced by feed type but inoculant source with Fis1 was significantly higher (p<0.05) than Fis2, Abo2, and Abo1. The ammonia, VFA concentration, IVDMD, and IVOMD were influenced by interaction between inoculant sources and feed types. Although inoculant from cattle close to the laboratory (Fis2 and Abo2) were better in term of higher bacterial population, higher fermentability and digestibility for most type of feeds but other sources can be used in vitro study without differences in average fermentability and digestibility results.

Lectio Praecursoria: Routine work: Authorizing representation in East Javanese regional politics
Authors: Wilenius Heikki 
Published: March 2021

This lectio summarizes a PhD study of the public activities of East Javanese regional councillors. Analysing the communication of these politicians, the thesis focuses on the ways they authorize their status as representatives of their constituency. The study finds that politics in East Java has a wide selection of authorizations, the use of which depends on the party, the political history, the age, and the gender of the politician. For the councillor, the most decisive factor for the choice of authorizations, however, is the political context. Different public institutions of politics are examined: meetings with the constituency during council recess, public hearings on draft bylaws, election campaign events, and regional council plenary sessions. The authorizations used in these contexts vary greatly, for example, concerning their aspect of ritualization, style of oratory, or way of evidence presented.

Full STEAM ahead, but who has the map? – A PRISMA systematic review on the incorporation of interdisciplinary learning into schools
Authors: White Daniel , Delaney Seamus 
Published: March 2021

Science, Technology, Engineering and Mathematics or "STEM" focused pedagogy has been influenced changes in education for decades. Responding to the need for interdisciplinary skilled workforces, the STEM approach has been revised firstly to reflect the incorporation of Arts, (STEAM) and, more recently, to place stronger emphasis on cross-disciplinary connections. However, there is little empirical evidence to drive the development of a practical model for classroom implementation. This systematic review aims to consolidate existing empirical evidence on the incorporation of interdisciplinary learning via a STEM/STEAM approach in high-school environments using a PRISMA review scaffolding. The review identified ninety-nine articles that addressed interdisciplinary learning. However, the majority of them were excluded due to the lack of empirical evidence for such improvements, resulting in only eleven studies being included in the final synthesis. This suggests that more research is required prior to wide-scale implementation within high school education systems. Of those that met the selection criteria, the overarching theme was that improved outcomes were best achieved via either a real-world project-based or problem-based learning pedagogy with the use of community and industry support. However, due to the low number of studies found to fit the criteria, it is recommended that further research is conducted to provide greater empirical evidence to support this finding.

Lettuce (Lactuca sativa L.) is a horticultural plant that is beneficial for health. Efforts are being made to expand the plant area. One of them is by utilizing marginal land such as peatlands. Peatlands in Indonesia are the most extensive soils in various tropical countries in the world that have low soil fertility and high acidity so that they are not optimal for lettuce growth. The provision of organic material can increase soil fertility by improving physical, chemical, and biological soil properties so that it can support lettuce growth. This study aims to determine the dose of cow manure and the dosage of oil palm empty fruit bunch fertilizer and the optimal dose interaction for growth and yield of lettuce. This research was conducted from June 2019 to August 2019 in Bengkulu City. This study uses a Completely Randomized Design consisting of two factors, which are repeated three times. The first factor is the dose of cow manure with three levels, namely: 0 tons ha-1, 15 tons ha-1, and 30 tons ha-1. The second factor is the dose of oil palm empty fruit bunch fertilizer, which consists of four levels, namely 0 tons ha-1, 5 tons ha-1, 10 tons ha-1, and 15 tons ha-1. The results showed that the dosage of cow manure 15 tons ha-1 and without the application of empty fruit bunches fertilizer gave the best results in leaf length of 18.674 cm. The best dose of cow manure for growth and yield of lettuce is 15 ha-1. The application of OPEFB fertilizer has not been shown to affect the growth and yield of lettuce.

Published: March 2021

Improving the efficiency of repair work in elimination of drilling pipe accidents in the well is an urgent task of oil companies and is achieved through usage of special devices and tools. Authors patented and manufactured a device for unscrewing pipes in casing with a nominal diameter of D = 114 mm. Cycle of the device for unscrewing pipes in the well consists of three periods: freewheeling, jamming of the carrier of the device for unscrewing the trapped pipes and the period of wedging. The article analyses the operating conditions of the device locking unit during the first two periods. Formulas for determining the force of pressing the cams to the casing during freewheel, as well as the moment of friction forces and friction power for this case are proposed. We obtain the dependence of the maximum allowable initial angle of jamming on the coefficient of friction and geometric parameters of the device.
It is planned to test the device for unscrewing pipes in industrial conditions of LLC "Factorial" (Poltava).

During exploitation of PVC products, the negative impact of high temperatures and light, and also the destructive influence of various microorganisms, leads to the deterioration of physical-mechanical properties and change of products painting. For prevention of the dehydrochlorination process of PVC, it is necessary to use the effective complex stabilizers, including biostabilizers, differing with their high processability and simultaneously possessing biocidal properties.
In this work the results of investigations of influence of the synthesized sulphur-containing epoxycyclopropanes as stabilizing additives for prevention of the dehydrochlorination process of the compositions based on plasticized PVC have been presented. The influence of these compounds as co-stabilizers in the composition of complex stabilizers – stearates Ca (CaSt2) and Zn (ZnSt2) on thermo- and light stability of PVCcompositions and also on their physical-mechanical and exploitation indices has been studied. It has been established the synthesized epoxy- and cyclopropane-containing mono- and disulphides jointly with stearic acid salts form the synergic mixtures, which can improve the physical-mechanical properties of PVC compositions, their thermal and light stability.
VALUE-SENSE MANAGEMENT

The greatest crisis, which is being experienced by the world economy, has not come unexpectedly, since it was predicted with a sufficient degree of precision. Moreover, the matters, causing obstacles for the transformation in the period of transition from the mixed economy to the intellectual economy, have been studied well enough and the technologies of the harmonious transformation have not just been developed but also successfully approbated. However, the crisis is escalating with increasing strength, and many analysts are warning against the risk of irreversible losses, that threaten the mankind with self-destruction due to the effect of 'the lacuna' and 'the gap' between the speed of changes in life conditions and the velocity of growth of human and humanity abilities to adapt to fast changing conditions of ecological, economic, technological and political reality.
As anticipated, the main problem turned out to be the intellectual inertia. Despite the fact that the system analysis of the global crisis in education, which does not any longer provide the human and humanity with the proper competencies, even those necessary for the survival, was published by F.G.Coobles back in 1968, the approaches which are long outdated and, therefore, have become dangerous, are still widely spread all over the world. The reports of the Roman club have repeatedly highlighted that the overcoming of 'the lacuna' effect requires new approaches to education, but this has not led to large scale practical results, in spite of the fact, that the task of the development of the new system of the continuous anti-crisis education (for all ages) was accomplished back in the USSR and the experimental model proved to be efficient in process of the 20 years approbation in conditions of the Russian Federation. The psychological bareers arising during the transition from the programme goal method to the system-synergetic approach, from the crisis model of economy to value-sense one, from the subject-object relations to the subject-subject ones and others, have turned to be hard to overcome without the help of specialists, equipped with the methods of the value-sense management, which enable each subject, experiencing the negative impact of the modern economic crisis, to successfully overcome it. This article is dedicated to the peculiarities of the author's scientific-practical school of the value-sense management as a means of overcoming the modern economic crisis.
ON ACCESSORY OBLIGATIONS IN RUSSIAN CIVIL LAW
Authors: Truhan R. 
Published: March 2021

In the science of civil law, two approaches to the understanding and interpretation of accessory have been formed. The first approach can be defined as the understanding of accessory in the "narrow" sense, the second - in the "broad" sense. Russian civil law contains signs of accessory in the "narrow" sense. For this reason, the problem of the concept of "accessory" is seen, which is subject to the identification of an accessory legal relationship with a security obligation, which in turn impoverishes the idea of the role of accessory in the system of legal relationships. With the development of circulation and the complication of law, examples of accessory legal relations of a different kind appeared that were not related to security obligations, i.e. "Broad" understanding of accessory, which has an auxiliary, secondary nature of the obligation, which can not always have a security focus. Russian arbitration courts have developed a number of rules to make up for the shortcomings of the institution of accessory in Russian civil law, and the possibility of using accessory in the "broad" sense. It is concluded that de jure the concept of accessory in Russian civil law is reflected in the "narrow" sense, and de facto, accessory is applied in the "broad" sense.
Efficacité de l’hypnose pour prendre en charge la fatigue associée au cancer : une revue de la littérature internationale
Authors: Baussard L. , Cousson-Gélie F. , Nicklès I. 
Published: March 2021

Objectif : Les études qui s’interrogent sur l’efficacité des interventions non médicamenteuses, dans la prise en charge de la fatigue associée au cancer, comprennent le plus souvent des sessions d’activités physiques adaptées ou des prises en charge psychologiques. Parmi elles se trouve l’hypnose, mais elle est principalement proposée en combinaison avec une autre thérapie, limitant une interprétation en termes d’efficacité. À travers cette revue de la littérature, nous voulons comprendre quelle est la place de l’hypnose pour la prise en charge de la fatigue associée au cancer.
Méthode : Nous avons recherché les articles scientifiques indexés dans les bases de données Cochrane, PsycINFO, Pubmed et Web of Science. Les principaux mots clés étaient « fatigue », « cancer » et « hypnosis ». La qualité méthodologique des études a été évaluée.
Résultats : Quatre-vingt-deux études ont été recensées. Après sélection, 11 études ont été retenues à la lecture. Les résultats sur l’efficacité de l’hypnose seule (non combinée à une autre thérapie) ont porté sur 6 études. Bien qu’il faille distinguer l’hypnose délivrée par autrui, de l’autohypnose par audioenregistrement, nos résultats indiquent que 4 études rapportent une efficacité significative de l’hypnose pour réduire la fatigue des patients soignés pour un cancer.
Conclusion : Au niveau international, trop peu d’études évaluent l’efficacité de l’hypnose en oncologie. Ainsi, sur un symptôme spécifique comme la fatigue, les études se font encore plus rares. De plus, il est difficile d’évaluer l’efficacité d’une méthode pour laquelle l’homogénéisation de la procédure est difficile à mettre en place. Cependant, au regard de cette étude, l’hypnose présente un réel intérêt et une efficacité dans la réduction des symptômes de fatigue.

Objectives. This study describes a new approach to obtain para-tert-butylcumene by alkylation of cumene with isobutylene in the presence of catalysts, such as Amberlyst 36 Dry, KU-2-8, aluminum chloride, and tert-butyl alcohol and concentrated sulfuric acid.Methods. To determine the qualitative and quantitative composition of the compounds and reaction masses, the following analysis methods were used: gas–liquid chromatography (on the Kristall 2000M hardware-software complex), chromatomass spectrometry on an Agilent 6850 instrument equipped with an Agilent 19091S-433E capillary column (30 m × 250 μm × 0.25 μm), and nuclear magnetic resonance spectroscopy (on a Bruker DRX 400 instrument with an operating frequency of 400 MHz).Results. A significant quantity of meta-tert-butylcumene was obtained by the alkylation of cumene with isobutylene using several catalysts, along with para-tert-butylcumene. This study also showed that the use of the catalysts Amberlyst 36 Dry and KU-2-8 during alkylation in a closed system (autoclave) led to the formation of isobutylene oligomers, often in quantity greater than the target reaction product. Simultaneously, the alkylation of cumene with tert-butyl alcohol in the presence of concentrated sulfuric acid enabled the obtainment of only one isomer, para-tertbutylcumene, which is essential for the further production of high-purity para-tert-butyl phenol.Conclusions. Sulfuric acid alkylation of cumene with tert-butyl alcohol enabled the obtainment of an individual para-isomer of tert-butylcumene with a yield of 87–89% for the loaded tert-butyl-alcohol with a cumene conversion of ~30%.
