This work reports on the assembly of imine-linked macrocycles that serve as models of two-dimensional covalent organic frameworks (2D COFs). Interlayer interactions play an important role in the formation of 2D COFs, yet the effect of monomer structure on COF formation, crystallinity, and susceptibility to exfoliation are not well understood. For example, monomers with both electron-rich and electron-poor π-electron systems have been proposed to strengthen interlayer inter-actions and improve crystallinity. Here we probe these effects by studying the stacking behavior of imine-linked macrocycles that represent discrete models of 2D COFs. Specifically, macrocycles based on terephthaldehyde (PDA) or 2,5-dimethoxyterephthaldehyde (DMPDA) stack upon cooling molecu-lar dissolved solutions. Both macrocycles assemble cooperatively with similar ΔHe values of -97 kJ/mol and -101 kJ/mol, respectively, although the DMPDA macrocycle assembly process showed a more straightforward temperature dependence. Circular dichroism spec-troscopy performed on macrocycles bearing chiral side chains revealed a helix reversion process for the PDA macrocycles that was not observed for the DMPDA macrocycles. Given the structural similarity of these monomers, these findings demonstrate that the stacking processes associated with nanotubes de-rived from these macrocycles, as well as for the corresponding COFs, are complex and susceptible to kinetic traps, casting doubt on the relevance of thermodynamic arguments for improving materials quality.

Обсуждаются некоторые теоретические аспекты реконструкции мировоззрения и идеологии древних обществ, фрагментарно или совсем не отраженных в памятниках письма. Отмечается особая диагностическая роль формульных выражений для компаративной истории мировоззрений. Возможности применения методов компаративной филологии и компаративного религиоведения демонстрируются на примере анализа таких формульных выражений, как др.- инд. urúḥ lokáḥ и праслав. *vоlьnъ(jь) světъ.
PERLINDUNGAN HUKUM BAGI ANAK KORBAN EKSPLOITASI SEBAGAI ARTIS
Authors: Hidayat Syarifuddin , Mahyani Ahmad 
Published: March 2019

Keberadaan artis cilik, sering dipandang sebagai pengembangan minat dan bakat, populer, finansial yang lebih, hidup dalam kemapanan. Sebenarnya semua itu lebih pada bentuk eksploitasi ekonomi yang dilakukan oleh orang tuanya, bilamana aktivitas artis cilik tersebut mengabaikan hak-hak asasinya sebagai anak. Kerja melebihi batas waktu yang ditentukan, jadwal on air dan off air yang padat, sehingga anak tidak sempat belajar, bolos sekolah, tidak punya waktu bermain dengan teman sebaya, merupakan pelanggaran terhadap hak-hak anak yang dilindungi oleh undang-undang. Beragam peraturan perundang-undangan di Indonesia yang tujuannya untuk melindungi anak ternyata belum dapat memberikan perlindungan yang memadai terhadap anak yang dieksploitasi secara ekonomi, dalam hal ini sebagai artis cilik. Beberapa kelemahan, ketidak harmonisan peraturan perundang-undangan yang ada dan kelemahan para penegak hukum (caturwangsa), berakibat pada lolosnya para pelaku eksploitasi anak sebagai artis dari sanksi hukum. Selain faktor ekonomi, perhatian dan kepedulian masyarakat terhadap anak yang dieksploitiasi secara ekonomi serta konstruksi sosial bahwa orang tua berhak atas segala sesuatu terhadap anak, memberi kontribusi pelanggaran hak-hak anak berupa eksploitasi itu terus terjadi.

A Comprehensive Literature Study on Microfibres from Washing Machines
Authors: Schöpel Bettina , Stamminger Rainer 
Published: March 2019

AbstractThe ubiquitous finding of microplastic in the abiotic and biotic environment has gained a lot of attention recently in the media, scientific community and among the general public. One of the known sources of microfibres is the washing of textiles. It would be a conceivable option to install filters in domestic washing machines that would sift out microplastics to prevent this pollution. The aim of this paper was to conduct a comprehensive literature search on microplastics filters in washing machines published already. Although the results of this research show that there has been an effort to find solutions for this problem in a worldwide context, there has been no known proven system that prevents microfibre release in the aquatic environment which does not have a harmful influence on the washing behaviour and/or washing results.

Authors: Habbal S. , Haddou B. , Canselier J. P. , Gourdon C. 
Published: March 2019

AbstractThis study aimed to investigate the simultaneous removal of methylparaben (MePB) and propylparaben (PrPB) from effluents (each one at 16 mg/L) using a nonionic micellar system containing Triton X-114. Response surface methodology (RSM) has been carried out. Extraction results using nonionic surfactant two-phase system were considered as a function of surfactant concentration and temperature variation. Four responses were investigated: MePB and PrPB extraction yield (E), solute (Xs,w) and surfactant (Xsf,w) concentrations in the aqueous phase and the volume fraction of micellar phase (ϕC) at equilibrium. Very high extraction efficiencies (99 % for PrPB and 84 % for MePB) were achieved at optimal conditions. Thereby, the amounts of PrPB and MePB were reduced 80 and 5 times, respectively. The extraction improvement using sodium sulfate was also shown. Finally, the solute stripping from micellar phase by pH change was proved.

AbstractThe adsorption of sodium dodecyl sulfate (SDS) and N,N-dimethyldodecan-1-amine oxide (DDAO) and their mixtures from their solutions, onto Jordanian Natural Clay (JNC) was investigated at room temperature. The clay was firstly analyzed with X-ray fluorescence technique. The surface tension of the single and mixed surfactant solutions was then measured as a function of the total surfactant concentration and the critical micelle concentration (CMC) values of these solutions were determined. The interaction between SDS and DDAO as indicated by their interaction parameter was calculated according to the regular solution model. Adsorption of single surfactants onto 3 % wt/vol Jordanian Natural Clay, using the depletion method, was ultimately investigated. Although no absorbed SDS molecules were found onto the Jordanian Clay, but a pronounced adsorption tendency for DDAO and mixed SDS/DDAO molecules was obtained. The amounts of surfactant adsorbed onto 3 wt/vol% JNC follow the trend: SDS/DDAO > DDAO > SDS indicating the importance of synergistic interaction of surfactants on their adsorption behavior.

Published: March 2019

O objetivo deste trabalho foi avaliar a vegetação do Parque Nacional das Emas antes e após a ocorrência de fogo, por meio do NDVI. Para a obtenção do NDVI foram utilizadas imagens do satélite ResourceSat-1, em julho/2010 (antes) e setembro/2010 (após). Foram aleatorizados pontos amostrais nas classes mais representativas de vegetação do PARNA, sendo: 60 pontos na classe Campo, 45 pontos na classe Cerrado, 35 pontos na classe Várzea e 35 pontos na classe Mata. Os valores encontrados de NDVI nos pontos amostrados, antes e após a ocorrência do incêndio, foram comparados estatisticamente pelo teste de qui-quadrado (χ²). Para quantificar a perda de biomassa após o incêndio, a imagem NDVI antes do incêndio foi subtraída da imagem NDVI após o incêndio, gerando assim uma imagem da diferença. Esta imagem foi classificada em cinco classes: baixa, moderada, média, alta e muito alta. Os resultados mostraram que houve diferença significativa nos valores de NDVI antes e após o incêndio, para todas as tipologias. Em relação a perda de biomassa, a classe Alta foi a mais representativa entre todas mapeadas, representando 41,1%, seguida pela classe Média (40,6%) e a classe mais extrema Muito Alta com 7,4%. O incêndio afetou, significativamente, as tipologias do parque.Palavras-chave: savana, incêndios florestais, severidade de incêndio, unidade de conservação. APPLICATION OF NDVI IN VEGETATION ANALYSIS AFTER FIRE OCCURRENCE ABSTRACT: The objective of this work was to evaluate the vegetation of Emas' PARNA before and after the occurrence of fire, through NDVI. In order to obtain the NDVI, we used images from the ResourceSat-1 satellite, in July/2010 (before) and September/2010 (after). Sampling points in the most representative PARNA vegetation classes were randomized: 60 points in the Campo class, 45 points in the Cerrado class, 35 points in the Várzea class and 35 points in the Mata class. The NDVI values found in the sampled sites, before and after the occurrence of the fire, were compared statistically by the chi-square test (χ²). To quantify biomass loss after fire, the NDVI image before the fire was subtracted from the NDVI image after the fire, thus generating an image of the difference. This image was classified into five classes: low, moderate, medium, high and very high. The results showed that there was a significant difference in the NDVI values before and after the fire, for all types. In relation to the loss of biomass, the Upper class was the most representative among all mapped, representing 41.1%, followed by the middle class (40.6%) and the most extreme class Very High with 7.4%.Keywords: savannah, forest fires, fire severity, conservation unit.

Exercise plays an important role in variables that involve concern about individuals' physical appearance. Therefore, the effect of sedentary women between the ages of 25-35 on the effects of the exercises they participated for recreational purposes on the levels of social physics anxiety was the aim of the study. 65 sedentary women participated in the study voluntarily. Pilates group (PG, n=20), Fitness group (FG, n=23) and control group (CG, n=25) were divided into three groups. PG and FG perform the exercise 3 days a week for 3 months. The control group did not perform any exercise. Statistics were performed by using SPSS package program. Conformity of data to a normal distribution was evaluated by Shapiro-Wilk test. Normally distributed data were expressed as mean and as standard deviation. Paired-t-test was used for the pre-test and used the post-test comparison of the data, while Repeated Measures ANOVA was used for intergroup comparisons, and Unpaired t-test was used to determine to originate on which group was the difference. Accordingly, after 3 months of an exercise, there was a significant difference between body weight, body mass index and pre-end values of social physique anxiety (SPA) in PG and FG (p &lt;0.05). Pair-wise comparisons, this resultant difference was between exercise groups and the control group (p &lt;0.05). As a result, it is possible to mention the positive effects of recreational exercises in social physics anxiety.

Ways of efficiency increasing of iron ore raw materials concentration technology
Authors: Pelevin A. E. 
Published: March 2019

Iron ore raw materials quality to a great extent determines technical and economic indices of metallurgical production. A brief characteristic of main types of iron ores of Russia quoted. It was shown, that they require concentration for utilization them in metallurgical production. Concentration flow charts of main types of iron ores considered. Main ways of iron ore raw materials concentration flow charts perfection directed on concentrates quality increase, concentration specific costs decrease and increase of raw materials utilization complexity. At Lebedinsky mining and concentration complex (MCC) at the expense of additional milling and concentration of high quality concentrate, a super-concentrate is produced having the iron mass content no less than 69.5% and silica content no more than 3.5%. The increase of iron mass content is 1.5–2%. At Mikhajlovsky MCC additional concentration of regular concentrate with iron mass content 65.5–66% enables to produce a super-concentrate having the iron mass content no less than 69% and silica mass content no more than 3%. The increase of iron mass content is 3–3.5%. Fine hydraulic screening is used at Kostomuksha and Kovdor MCCs for adjusting of regular concentrates. The undersize of sizing screens is a high quality concentrate, and oversize fraction is an intermediate product subjected to additional milling and concentration. When using the fine hydraulic screening, the super-concentrates are not obtained. Indices of super-concentrates production with application of separation in an alternative magnetic field quoted. Low complexity of iron ore raw materials utilization is typical at concentration of hematitemagnetite quartzite ores. In Russia the hematite-magnetite quartzite ores are mined and concentrated at three MCCs as follows: Olenegorsky, Mikhajlovsky and Kimkano-Sutarsky. Flow-charts and indices of magneto-gravitation concentration quoted, applied for hematite concentrate production. Stage separation of not only tails but also of concentrates is one of methods of expenses decreasing. A diagram of concentrate stage separation with application of concentration method or fine screening considered. Results of industrial application of flow-charts with concentrate stage separation quoted, the application taken place at Kachkanar MCC with application of two methods – wet magnetic concentration and fine hydraulic screening.

Authors: Yur’ev B. P. , Dudko V. A. 
Published: March 2019

Input of intensifying additives, influencing the strengthening of iron ore pellets, can be one of methods to strengthen the pellets and to decrease the volume of fines in them. Boron oxide ore borate ore can be used as such additives. Study of technology aspects of boron-containing pellets production and elaboration of technology of boron input into Kachkanar vanadiumcontaining raw materials was the purpose of the study, aimed at exclusion from BF burden of sinter, which does not contain vanadium. A possibility was justified to use borate ore at iron ore pellets production by a partial substitution of bentonite. Influence of borate ore additives on pellets metallurgical properties studied. As a result of laboratory studies it was determined, that the borate ore has not binding properties and its utilization is possible only in a mixture with bentonite. Optimal content of borate ore in pellets determined, exceeding of which a decrease of reducibility is observed, accompanied by a considerable swelling, which makes impossible the utilization of such pellets in blast furnaces. It was shown, that input of optimal volume of borate ore additives enables to keep the reducibility and swelling at the level of Kachkanar pellets being produced. The mechanism of borate ore content influence on strength characteristics of burnt pellets and their behavior during reducing studied. The regularity of borate ore additives influence on cold and hot pellets strength determined. It was determined, that at input of 0.5% of borate ore practically does not influence on the pellets reducibility while swelling will be constant. The input of borate ore up to 2% will result in a sharp increase of swelling. The decrease of reducibility with simultaneous increase of swelling of pellets having more than 0.5% of borate ore does not allow using such pellets in blast furnaces. Recommendations provided for slag regime optimizing, decreasing of metal losses with slag and test BF heats of pellets, having optimal additives of borate ore and bentonite carrying out.
