Simple in situ chemical oxidation method was employed to prepare different molar of HCl doped DL−PLA/PANI composites using AnHCl as precursor. Surface morphology, ATR−FTIR, UV–Visible, and band gap were studied. PANI nanowires with different diameter and smooth surface were observed for composites. The lowest direct band gap was found to be 1.68 eV for 2 (M) HCl doped DL−PLA/PANI. DC conductivity at room temperature was measured and followed the ohmic behaviour. The calculated highest DC conductivity at room temperature was found to be 0.1628 × 10−2 (S/cm) for 2 (M) HCl doped DL−PLA/PANI. Temperature variation (70−300 K) DC conductivity without magnetic field of as prepared composites was analysed using linear four probe techniques and showed semiconducting nature. The conductivity in the range of temperature (70−300 K) follows 3D VRH hopping mechanism. In kivelson model, the exponents are increased with increasing dopant concentration and was obeyed the power law. MR of the prepared DL−PLA/PANI composite films is strongly dependent on temperature, magnetic field, and concentration of HCl dopant. Negative MR is discussed in terms of a wave function−shrinkage effect on hopping conduction. In addition, we were discussed the response of carbon monoxide (CO) gas with polyaniline-based sensor materials.
Resolution of the M-shape Pattern of the Outdoor Air Temperature Environmental Kuznets Curve (EKC) for Metropolitan Areas in a Country: Using Long-term Monthly Level Data of Taipei City as Empirical Evidence
Authors: Huang Wu-Jang
Published: November 2021

In Taiwan, the heat island effect is the most significant in Taipei City. Thus this research provides a causal explanation for why urban outdoor air temperature has an M-shape EKC pattern for metropolitan areas in a country. Results show that the growth rate change in CO2 concentration can induce changes to the periods of the La Nino effect and EI Nino effect, causing high fluctuations in rain accumulation. The amount of rain then alters A-type evaporation, and so the evaporation amount is the top factor for the diffusion of a city’s heat. This fluctuation plays as a cooling and heating source for the V region of the M shape in the outdoor air temperature EKC pattern. In our previous studies, the growth rate change in CO2 concentration correlates to the energy structure. Therefore, a heat sinking model has been proposed to explain the accumulation of heat in a city, in which a proportion process for the solar irradiation source from buildings and remodeling engineering from a public housing policy and the private sector can play as a heating source of the two peaks of the M shape and present long-term linear growth in the outdoor air temperature EKC pattern.

Among the visceral manifestations of NDST in pregnant women most often diagnosed mitral valve prolapse (20-25%) that accompanied by more cardiovascular and obstetric complications during pregnancy. It demonstrates the high clinical significance of the problem of connective tissue dysplasia with mitral valve prolaps for pregnancy and requires adequate treatment programs for prevention of complications and management of pregnant women with connective tissue dysplasia. Aim. Determination of the frequency of pregnancy pathology in women with clinical signs of NDST and MVP complicated by extrasystolic arrhythmia. Materials and methods. 138 pregnant women with MVP and concomitant signs of NDST and 54 healthy pregnant women were selected for analysis. Clinical manifestations of NDST, different variants of arrhythmias and the total number of complications of pregnancy and childbirth were evaluated. Results. In pregnant women with clinical signs of NDST and MVP complicated by extrasystolic arrhythmia, cases of frequent sinus extrasystole were significantly more often compared to frequent ventricular arrhythmia (47.8% vs. 18.1%, p<0.001) and cases of combination of frequent sinus extrasystole and ventricular arrhythmia (13.3 % vs. 1.5%, p <0.05). They significantly more often identified both symptoms of arrhythmological nature and symptoms that indicated a violation of autonomic status. The presence of NDST syndrome is more often accompanied by the development of complications of pregnancy and childbirth. These pregnant women have genetic and phenotypic risk factors for the development of pathological pregnancy and childbirth, birth trauma, disability of mother and newborn, which justifies such patients in a separate risk group for individualized programs of the prevention and treatment of visceral (cardiac) manifestations of NDST and possible complications of pregnancy and childbirth. Conclusions. 3.1% of pregnant women are diagnosed with phenotypic signs (stigma) of undifferentiated connective tissue dysplasia, and the most common visceral cardiac manifestation is mitral valve prolapse. The presence of mitral valve prolapse and extrasystolic arrhythmia in pregnant women with NDST is accompanied by significantly more frequent development of pregnancy and childbirth complications in these patients.

Masjid merupakan salah satu tempat untuk menyampaian pesan moral dari para penceramah, khotib, ustad, guru ngaji kepada para jamaahnya. Kualitas audio yang baik dan jelas dalam masid menjadi suatu keharusan. Ketika sistem tata suara di mesjid terganggu seperti suara tidak jelas, muncul feedback bahkan hal terburuk sampai speakernyamengalami kerusakan akan menjadi masalah bagi para jamaah untuk menerima informasi dari para penceramah. Hal ini terjadi di Masjid Luqmanul Hakim POLBAN. Delapan buah speaker dinding 60W 8Ω yang terpasang sering sekali mengalami kerusakan. Speaker tersebut dicatu oleh 2 buah Amplifier Stereo dengan total daya keluaran 480Wtiap kanal. Tidak dipasang alat Sound Compressor atau limiter mengakibatkan speaker menjadi rentan terhadap kerusakan ketika ada kenaikan daya akibat feecback atau setting volume terlalu besar. Metode yang dilakukan untuk mengatasi masalah tersebut yaitu melakukan observasi dan analisis spesifikasi dan istalasi pada peralatan soundsystem yang sudah terpasang. Ada dua opsi untuk mengatasi masalah salah instalasi sound system tersebut. Pertama speaker dipertahankan maka Amplifier diganti dengan yang memiliki daya keluaran per kanal maksimum 120W di impedansi 8Ω. Atau diganti speaker dengan yang memiliki daya total per kanal 480W. Dari ujicoba lapangan dipilih opsi 2 oleh pengelola masjid dan hanya satu Amplifier saja yang digunakan. Hasil setelah tiap kanal dipasang masing-masing 2 buah speaker 240W/8Ω secara paralel diperoleh suara yang cukup jelas tanpa distorsi dengan besar SPL rata-rata 72,9dB dan setelah dilakukan ujicoba selama 3 bulan tidak ada masalah.

Students’ evaluations of teaching (SETs) have been an important and the most commonly used method for evaluating teaching quality in higher education institutions. They provide feedback from students to faculty and administrators. The majority SET instruments used in Indonesia were developed based on the faculty/administrators’ knowledge and experience or adopted from other higher education institutions with or without modifications. This study aims to develop a SET instrument based on both educational theory and empirical data. Using data collected from a total of 755 students of Politeknik Negeri Bandung, the underlying dimensions and the psychometric properties of the instrument were tested. The exploratory factor analysis generated a three-factor solution. A confirmatory factor analysis was then run to cross-validate the item indicators of each factor/dimension. The reliability and validity of the instrument were also tested. The final version of SET instrument encompasses 15 items in three dimensions. The three dimensions were labeled as preparation and organization (4 items), instructional delivery (7 items), and examination and feedback (4 items). Although it was developed using student samples from Politeknik Negeri Bandung, the newly developed instrument can be used in any higher education institutions.

In the past ten years, sustainable supply chain management (SSCM) attach great importance due to consumers, for-profit and profitless organizations, laws and regulations to the social and corporate responsibilities of consumers, so it has been recognized by practitioners and scholars. Supplier selection, environmental effect like a lockdown, and social cooperation and other SSCM programs can play an important part in realizing the triple bottom line (TBL) of economic, environmental, social assistances. In supply chain management (SCM), the sustainable supplier selection (SSS) and firm performance plays an important role. Traditionally, when evaluating SSS performance, organizations will consider a new framework to obtain the overall criteria/sub-criteria of the sustainability index by encapsulating sustainability. In this paper 12 sub-criteria for 3 pillars of sustainability as economic, environment and social performance is collected. Although there are many articles on SSS and evaluation, so far, research on sustainability issues is very limited. This study endeavours to propose a fuzzy multi-criteria approach to discuss SSCM planning, and studies the issue of determining a current model for SSS in the supply chain during COVID-19 based on the TBL method. For express the linguistic value of the subjective preference of experts we use triangular fuzzy numbers. By using fuzzy numbers to find standard weights for qualitative performance evaluation, then fuzzy TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is proposed to find the ranking of SSS. However, COVID-19 has a negative role in SSS and in firm performance. The situation of lockdown due to COVID-19 has a negative effect on the performance of the organizations. An example is given of the proposed method.

Transition-metal dichalcogenides (TMDCs), such as MoS2, lack their inversion center in monolayers, exhibiting in-plane piezoelectricity at a nanoscale thickness. In conventional piezoceramics devices, the operating mechanism has been well established that piezocharges appear at crystal edges and how these charges act in capacitor structures. Although TMDC monolayers are expected to possess a unique system due to their semiconductor nature, strong interaction with contact metals alters physical properties predominantly. In this study, we identify the position of piezocharges in MoS2 generators based on the displacement current under dynamic strain. The present results provide new insights for future device engineering.
DISTRIBUTION OF ALIEN ZOOBENTHIC SPECIES ON THE SHELF OF THE BLACK SEA
Authors: Shalovenkov N. N.
Published: November 2021

The number of alien species in the zoobenthos of the Black Sea increased up to 65 species. Depending on the scale of their distribution in the Black Sea, non-native zoobenthos species are combined into three groups: 1) 5 species have spread in the entire sea, 2) 35 species were found in several areas, and 3) 25 species were found only in one of the areas of the sea. Six areas of the Black Sea shelf have been identified (Varna - Burgas, Danube, Northwestern, Crimean, Caucasian and Anatolian) in accordance with the seasonal and annual values of the thermohaline characteristics. The zoobenthos differed not only in quantity, but also in the composition of non-native species between the six areas of the shelf. The results of multivariate statistical analysis revealed a low level of similarity between these areas of the Black Sea shelf. The greatest similarity in the composition of alien species of zoobenthos was observed for the Danube region with the Varna and Burgas bays, which border each other. The species composition of the alien species of the Caucasian shelf was more similar to the Varna - Burgas and Danube areas than to the neighboring Crimean and Anatolian areas. Spatial gradients of temperature and salinity form hydrological fronts of water masses, which are a kind of ecological barriers and can limit the natural exchange of alien species between shelf areas.
PRELIMINARY ESTIMATION OF THE INFLUENCE OF CYDALIMA PERSPECTALIS INVASION ON THE SPECIES COMPOSITION AND STRUCTURE OF EARTHWORM POPULATION (OLIGOCHAETA: LUMBRICIDAE, ACANTHODRILIDAE) IN THE RANGE OF BUXUS SEMPERVIRENS (WESTERN CAUCASUS)

The earthworm fauna and population structure in Colchic ecosystems of the southern slope in the Western Caucasus were studied. First, in May 2013 we have sampled earthworms of the forest communities. This research was repeated in 2018 after Buxus sempervirens L. destruction by Cydalima perspectalis Walker (Lepidoptera, Crambidae). Altogether 13 earthworm species were registered in the soils of original B. sempervirens phytocenose and derived phytocenoses of the Western Caucasus. Endemicity of earthworms in the study area was higher than in most regions of Russia. The earthworm samples in 2013 and 2018 were similar in species composition, but differed in terms of dominant species. The structure of the earthworm population in the soils of the secondary phytocenoses has become closer to the earthworm communities of the other forests in the Western Caucasus. Analysis of the relative position of taxocenes in 2013 and 2018 space NMDS model, allows to put forward a hypothesis about the reduction of their total "ecological niche" after the disappearance of B. sempervirens . We believe that a broader “ecological niche” in 2013 is associated with a greater mosaicism (diversity) of the worm habitat formed by boxwood communities.

The data on distribution of small spruce bark beetle Ips amitinus (Eichh.) (Coleoptera: Curculionidae: Scolytinae), a new invasive pest of European origin on the territory of Western Siberia are presented. Alien bark beetle species was recorded in the Siberian pine forests of the Tomsk, Kemerovo and Novosibirsk regions. According to the modern data the total invasion range is more than 30 thousand km² with a tendency to further expansion. The number outbreaks of I. amitinus in Siberian pine forests near settlements, in nature preservations and plantations of Pinus sibirica Du Tour cause significant harm to pine-nut harvesting and selective breeding.

Published: November 2021

The results of studies on the distribution of alien species in macrozoobenthic communities in the reservoirs of the Kama River cascade are provided. Twenty five alien species of the Ponto-Caspian and Ponto-Azov origins and 1 species - a representative of the Lake Baikal fauna - were registered. Differences in the species composition and structural characteristics of invaders of macrozoobenthos in the Kama and Volga reservoirs were shown. It was noted that mollusks of the genus Dreissena dominate in biomass in most of the studied biotopes. Three types of coenotic complexes of alien species have been identified: psammorelophilic profundal, characteristic for the Nizhnekamsk Reservoir and the Volgo-Kamsky and Kamsky reaches of the Kuibyshev Reservoir; the psammorelophilic coastal in Nizhnekamsk Reservoir; and the psammorelophilic coastal in Votkinsk and Kama reservoirs.
