Published: May 2021

The demand for professional development for teachers in higher education is paramount. In doing so, the teachers must have a good professional development scheme in upgrading their knowledge and skills in performing their main duty. This research was aimed at investigating the areas of teachers’ professional development which are supported by the implementation of peer review in team teaching. It also aims at exploring the challenges in applying team teaching. This study applied qualitative research design with the interview as the data collection method and four English teachers as the participants of the research. The result showed that there are three aspects of TPD which occur. The first one is an attitude which becomes better in terms of improved awareness of the teachers. The other element is self-esteem where it is also improved due to the feedback given after the peer review. While the third is patience. As suggested in the feedbacks, teachers require to be more patients in dealing with misbehaving students. As for the challenges, it can be concluded that they come from two different sources. The first one is from the individual teacher where they think that some of the suggestions cannot be done or too hard to do. The second one is, Since TPD requires funding, the institution should also provide necessary and sufficient funding to support the TPD. This can be done by setting up the policy dealing with the sustainable TPD which, in turn, will give more benefits to the institution.

Здійснено екологічне оцінювання стану поверхневих водойм Житомирського району на вміст хлоридів і сульфатів. Дослідження проведено на річці Тетерів та її притоках, водосховищі Відсічному, з якого здійснили водозабір для питного водопостачання м. Житомира, нижче та вище скидів ОСК-1 та ОСК-2, кар'єрі силікатного заводу, упродовж 2017-2019 рр. Поверхневі водойми є найбільш вразливими джерелами води, оскільки ніяк не захищені від зовнішніх впливів і саме вони першими приймають на себе всі забруднювачі, що утворюються внаслідок природних явищ і діяльності людини. У законодавстві України вміст сульфатів і хлоридів у поверхневих водоймах не регламентується жодним нормативним документом, тому воду оцінювали, прирівнюючи її показники до нормативів вод, призначених для питного (централізованого) водопостачання. Більшість суб'єктів централізованого водопостачання Житомирського району здійснюють забір води саме з поверхневих водойм, а Житомир – безпосередньо з річки Тетерів. Аналізи води здійснювали посезонно впродовж досліджуваних 2017-2019 рр., оскільки на значення показників впливають температурний режим та обсяги води у річках (наповненість). Найбільший вміст обох досліджуваних агентів виявлено влітку та восени, особливого в першу половину осені, коли температура води була ще добре прогрітою. Окрім цього саме в цей період спостерігається найнижча водність річки Тетерів і її приток, що сприяє збільшенню концентрації забруднювачів на одиницю об'єму. Серйозно впливали на вміст досліджуваних забруднювачів і місця відбору. Найбільше значення показників спостерігали на річці Тетерів влітку та восени 2017 р., нижче скиду ОСК-2, куди скидаються води з промислової зони. Хоча перевищень допустимих показників по обох досліджуваних забруднювачах не виявлено згідно з державними санітарними правилами і нормами ДСанПіН 2.2.4-171-10 та державним стандартом ДСТУ 4808: 2007, однак в окремих місцях відбору вміст хімічних агентів викликає занепокоєння. У динаміці досліджуваних років найбільший вміст забруднювачів зафіксовано у 2017 р. Сезонна динаміка свідчить про найбільше забруднення в теплу пору року. Особливо це стосується вмісту хлоридів у річці Тетерів нижче скидів ОСК-2. На підставі отриманих результатів можна стверджувати, що стан поверхневих водойм Житомирського району можна вважати задовільним.

Published: May 2021

Background: Non-specific low back pain is a type of pain that is located in spine area and does not radiate to the legs. Non-specific low back pain can limit daily activities and cause inability to do work. The aim of this study is to compare the effectiveness of proprioceptive neuromuscular facilitation (PNF) versus sensory motor training (SMT) in the treatment of ultrasound therapy (UST) and kinesio tape (KT) insertion in non-specific low back pain.
Methods: This research is an experimental with a randomized pre-test and post-test control group design, in which the study participants were divided into two groups randomly. The control group (n = 10) is given UST+PNF+KT combination, while the treatment group (n = 10) is given UST+SMT+KT combination. Therapeutic evaluation measures include: pain scale with a numeric rating scale, range of motion with a goniometer, and lower back disability with the Indonesian Version of Oswestry Disability Index. The intervention is given 3 times per 1 week for 3 weeks.
Results: The results showed improvement in pain, range of motion, and lower back disability in each group (p<0.05). However, there were no significant differences when compared between groups.
Conclusion: Based on these results, it can be concluded that the UST+PNF+KT combination has the same good results as the UST+SMT+KT combination in improving pain, range of motion, and lower back disability in non-specific low back pain.

Abstract
Measurement of magnetic field strengths in a molecular cloud is essential for determining the criticality of magnetic support against gravitational collapse. In this paper, as part of the JCMT BISTRO survey, we suggest a new application of the Davis–Chandrasekhar–Fermi (DCF) method to estimate the distribution of magnetic field strengths in the OMC-1 region. We use observations of dust polarization emission at 450 and 850 μm, and C18O (3–2) spectral line data obtained with the JCMT. We estimate the volume density, the velocity dispersion, and the polarization angle dispersion in a box, 40″ × 40″ (5×5 pixels), which moves over the OMC-1 region. By substituting three quantities in each box with the DCF method, we get magnetic field strengths over the OMC-1 region. We note that there are very large uncertainties in the inferred field strengths, as discussed in detail in this paper. The field strengths vary from 0.8 to 26.4 mG, and their mean value is about 6 mG. Additionally, we obtain maps of the mass-to-flux ratio in units of a critical value and the Alfvén Mach number. The central parts of the BN–KL and South (S) clumps in the OMC-1 region are magnetically supercritical, so the magnetic field cannot support the clumps against gravitational collapse. However, the outer parts of the region are magnetically subcritical. The mean Alfvén Mach number is about 0.4 over the region, which implies that the magnetic pressure exceeds the turbulent pressure in the OMC-1 region.

Abstract
We present a large statistical study of the fluctuation anisotropy in minimum variance (MV) frames of the magnetic field and solar wind velocity. We use 2, 10, 20, and 40 minute intervals of simultaneous magnetic field (the Wind spacecraft) and velocity (the Spektr-R spacecraft) observations. Our study confirms that magnetic turbulence is a composite of fluctuations varying along the mean magnetic field and those changing in the direction perpendicular to the mean field. Regardless of the length scale within the studied range of spacecraft-frame frequencies, ≈90% of the observed magnetic field fluctuations exhibit an MV direction aligned with the mean magnetic field, ≈10% of events have the MV direction perpendicular to the background field, and a negligible portion of fluctuations has no preferential direction. On the other hand, the MV direction of velocity fluctuations tends to be distributed more uniformly. An analysis of magnetic compressibility and density fluctuations suggests that the fluctuations resemble properties of Alfvénic fluctuations if the MV direction is aligned with background magnetic field whereas slow-mode-like fluctuations have the MV direction perpendicular to the background field. The proportion between Alfvénic and slow-mode-like fluctuations depends on plasma β and length scale: the dependence on the solar wind speed is weak. We present 3D numerical MHD simulations and show that the numerical results are compatible with our experimental results.

Abstract
We report on the results of multiwavelength follow-up observations with Gemini, Very Large Array (VLA), and Australia Telescope Compact Array to search for a host galaxy and any persistent radio emission associated with FRB 180309. This FRB is among the most luminous FRB detections to date, with a luminosity of >8.7 × 1032 erg Hz−1 at the dispersion-based redshift upper limit of 0.32. We used the high-significance detection of FRB 180309 with the Parkes Telescope and a beam model of the Parkes Multibeam Receiver to improve the localization of the FRB to a region spanning approximately

. We aimed to seek bright galaxies within this region to determine the strongest candidates as the originator of this highly luminous FRB. We identified optical sources within the localization region above our r-band magnitude limit of 24.27, 14 of which have photometric redshifts whose fitted mean is consistent with the redshift upper limit (z < 0.32) of our FRB. Two of these galaxies are coincident with marginally detected “persistent” radio sources of flux density 24.3 μJy beam−1 and 22.1 μJy beam−1, respectively. Our redshift-dependent limit on the luminosity of any associated persistent radio source is comparable to the luminosity limits for other localized FRBs. We analyze several properties of the candidate hosts we identified, including chance association probability, redshift, and presence of radio emission; however, it remains possible that any of these galaxies could be the host of this FRB. Follow-up spectroscopy on these objects to explore their Hα emission and ionization contents, as well as to obtain more precisely measured redshifts, may be able to isolate a single host for this luminous FRB.

The main objective of the project Common strategies and best practices to IMprove the transnational PRotection of ECOsystem integrity and services - IMPRECO is to enhance the safeguarding of ecosystems and ecosystem services. Additionally, the aim of this project is to tackle their environmental vulnerability by strengthening the potential of the Protected Areas in biodiversity, ecosystems and ecosystem services conservation. This is expected to be addressed by maintaining it through their transnational networking located in the European Adriatic-Ionian Macro-Region.
The aim of this research is: 1) to characterise the habitats and ecosystems involved in the coastal-marine protected areas considered; 2) to set a biodiversity baseline; 3) to understand what current ecosystems’ conditions are; 4) to build up a transnational biomonitoring programme of target species and habitats and 5) to assess their response to pilot actions. To do so, a transnational inventory of species, habitats, ecosystems and ecosystem services was established, starting with the seven coastal-marine protected areas involved in the project. Data collection was carried out using different sources of information: scientific literature, officially available data from NATURA 2000 Standard Data Forms, checklists from local biomonitoring programmes, personal observations and citizen science, historical maps and data from new in-field analyses. Data were filled in the transnational biodiversity geo-databases according to the NATURA 2000 standards about habitat features, species protection level and species features. The presence of alien species (non-indigenous species, NIS) was also acknowledged and references about data collection were provided in the databases according to the Darwin Core standards.

Abstract
Mucosal-associated invariant T (MAIT) cells are innate-like T cells that specifically target bacterial metabolites but are also identified as innate-like sensors of viral infection. Individuals with chronic HIV-1 infection have lower numbers of circulating MAIT cells compared with healthy individuals, yet the features of the MAIT TCR repertoire are not well known. We isolated and stimulated human PBMCs from healthy non-HIV–infected donors (HD), HIV-infected progressors on antiretroviral therapy, and HIV-infected elite controllers (EC). We sorted MAIT cells using flow cytometry and used a high-throughput sequencing method with bar coding to link the expression of TCRα, TCRβ, and functional genes of interest at the single-cell level. We show differential patterns of MAIT TCR usage among the groups. We observed expansions of certain dominant MAIT clones in HIV-infected individuals upon Escherichia coli stimulation, which was not observed in clones of HD. We also found different patterns of CDR3 amino acid distributions among the three groups. Furthermore, we found blunted expression of phenotypic genes in HIV individuals; most notably, HD mounted a robust IFNG response to stimulation, whereas both HIV-infected progressors and EC did not. In conclusion, our study describes the diverse MAIT TCR repertoire of persons with chronic HIV-1 infection and suggest that MAIT clones of HIV-infected persons may be primed for expansion more than that of noninfected persons. Further studies are needed to examine the functional significance of unique MAIT cell TCR usage in EC.

Authors: Oluwalola O.I , Fagbenro O.A 
Published: May 2021

This study was carried out to determine the fatty acid composition and sensory quality of Clarias gariepinus from different culture enclosures (plastic, sandcrete tanks and earthen ponds), at the Teaching and Research Farm of Department of Fisheries and Aquaculture Technology, Federal University of Technology, Akure, Ondo State, Nigeria. The comparative work was carried out to find out if habitat could influence the nutrient composition of the fish. Standard procedures were used in the analysis of tissue nutrient. Sensory evaluation study revealed differences in taste and texture indices considered for C. gariepinus reared in plastic, sandcrete tanks and earthen ponds (p<0.05). Fatty acid profiles of C. gariepinus were determined using Gas chromatography-mass spectrometry (GC-MS) method. The percentage of saturated and unsaturated fatty acids was higher (49.99%, 23.17%) in earthen pond cultured C. gariepinus than the plastic and sandcrete tanks. The study revealed that C. gariepinus raised in earthen pond possess fatty acid composition and sensory quality advantages over the plastic and sandcrete tanks.

Authors: Dong Yan , Xu Qing , Jia Xi , Li Chao , Xu Dan , Jiao Yang 
Published: May 2021

Purpose: To investigate the effect of thiamine triethylorthoformate conjugate (TTO) on Parkinson disease (PD) in vitro and in vivo in a mice model.
Methods: The effect of TTO on behavioural changes in PD mouse model was studied using pole, traction and swimming tests. Astrocyte proliferation after TTO treatment was assessed using 3 (4, 5 dimethyl 2 thi¬azolyl) 2, 5 diphenyl 2 H tetrazolium bromide (MTT) assay. Apoptosis was determined with flow cytometry using Annexin V Fluorescein isothiocyanate kit.
Results: Treatment of PD mice with TTO led to a decrease in climbing time, increase in suspension score and enhancement of swimming score, when compared to the untreated group (p < 0.05). Treatment of astrocytes with TTO prior to MPP incubation significantly increased proliferation (p < 0.05). Apoptosis induction in astrocytes by MPP was attenuated by pre-treatment with TTO. Pre-treatment of astrocytes with 10 µM TTO markedly reduced JNK activation, when compared to astrocytes incubated with MPP alone (p < 0.05). Up-regulation of Bax and down-regulation of Bcl 2 by MPP in astrocytes were attenuated by pre-treatment with TTO. MPP-induced up-regulation of cleaved caspase 3 was suppressed in astrocytes by TTO pre-treatment (p < 0.05).
Conclusion: Treatment with TTO prevents MPP+ -induced neuronal damage in vitro in astrocytes and in vivo in mice. The neuro-protective effect of TTO involves down-regulation of JNK activation, inhibition of caspase-3 level, decrease in Bax and increase in Bcl-2 expression. Thus, TTO has a potential for use in the treatment of Parkinson’s disease.
