Physical Activities and Learning Experience of Higher Education Students: Mediating Role of Quality of Life and Physical Self-Esteem

The impacts of physical activities (PAs) on psychological and physical health consequences have been examined in both nonclinical and clinical contexts. Although PAs’ influences on physical consequences are regularly beneficial, the psychological positive impacts are less well-understood. This study investigates the effects of PA on physical consequences (i.e., physical self-esteem) and psychological and cognitive consequences (i.e., quality of life and learning experience). PA has been found to improve quality of life (QOL), learning experience (LP), and physical self-esteem. Mixed findings from prior studies suggested that the relationship between these variables might be direct or indirect. Data were collected via a self-administrated questionnaire from 510 higher education students in different Kingdom of Saudi Arabia (KSA) universities. The collected data were analyzed by structural equation modeling (SEM) and the SmartPLS 4 program. The SEM results show that PAs directly help in enhancing the student learning experience. The results support the mediating role of student physical self-esteem and quality of life in the relationship between physical activities and learning experience. Several theoretical and practical implications were elaborated on and discussed, along with limitations and further research opportunities.
FAR-INFRARED AND ACCRETION LUMINOSITIES OF THE PRESENT-DAY ACTIVE GALACTIC NUCLEI

We investigate the relation between star formation (SF) and black hole accretion luminosities, using a sample of 492 type-2 active galactic nuclei (AGNs) at z < 0.22 ? > , which are detected in the far-infrared (FIR) surveys with AKARI and Herschel. We adopt FIR luminosities at 90 and 100 μm as SF luminosities, assuming the proposed linear proportionality of star formation rate with FIR luminosities. By estimating AGN luminosities from [O iii]λ5007 and [O i]λ6300 emission lines, we find a positive linear trend between FIR and AGN luminosities over a wide dynamical range. This result appears to be inconsistent with the recent reports that low-luminosity AGNs show essentially no correlation between FIR and X-ray luminosities, while the discrepancy is likely due to the Malmquist and sample selection biases. By analyzing the spectral energy distribution, we find that pure-AGN candidates, of which FIR radiation is thought to be AGN-dominated, show significantly low-SF activities. These AGNs hosted by low-SF galaxies are rare in our sample ( ∼ 1 % ? > ). However, the low fraction of low-SF AGNs is possibly due to observational limitations since the recent FIR surveys are insufficient to examine the population of high-luminosity AGNs hosted by low-SF galaxies.
Functional and biochemical characteristics of the muscle system in children with type I diabetes

Background. The purpose of the study was to determine possible markers of skeletal muscle damage in children with type 1 diabetes mellitus (T1DM) and their relationship with the features of disease course. Materials and methods. The observation group consisted of 98 children with type 1 diabetes mellitus: the first group included 22 people without disorders of the muscular system; the second — 42 patients with dynapenia; the third — 34 children with diabetic myopathy. Control group — 30 relatively healthy children. Assessment of the static endurance of skeletal muscles, determination of the level of creatine kinase, aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenase, periostin and cardiotrophin-1 in blood serum were performed in all patients. Results. The conducted studies demonstrate that children with diabetes, regardless of the structural and functional state of their muscular system, have signs of skeletal muscle damage, which were most expressed in diabetic myopathy and progressed with maximal deterioration of glycemic control. It was found that the highest content of alkaline phosphatase was characteristic of children from group 1, while in patients with diabetic myopathy its serum content was not statistically different from that of controls. These disorders occurred against the background of changes in alkaline phosphatase activity, the level of which was highest in children from group 1, while in patients with diabetic myopathy, its serum content was not statistically different from that of controls. At the same time, during the course of diabetic myopathy in children with T1DM, there was an increase in lactate dehydrogenase activity by 1.2 times (p < 0.01) and cardiotrophin-1 by 300 times (p < 0.01) compared to the corresponding indicator of the control group. Serum periostin level was increased in all patients with T1DM. Its maximum values were determined in group 1, whose periostin concentration exceeded control indicators by 103 times (p < 0.01). With deterioration of skeletal muscle state, there was a gradual decrease in periostin serum level, but in patients with dynapenia, it was 35.5 times higher than in the control group (p < 0.05) and 19.2 times higher in those with diabetic myopathy (p < 0.05). Conclusions. The course of type 1 diabetes in children is accompanied by skeletal muscle damage, the first clinical sign of which is a decrease in the static muscle endurance against the background of worsening disease course. Alkaline phosphatase, lactate dehydrogenase, periostin, and cardiotrophin-1 are biochemical markers of skeletal muscle damage in children with type 1 diabetes. A common feature of the changes in the specified indicators is their increase; however, each clinical condition of the skeletal muscles corresponds to its own configuration of changes in the abovementioned markers.
Strategi Menjaga Eksistensi Kearifan Lokal sebagai Identitas Nasional di Era Disrupsi

Penelitian ini memiliki fokus untuk mengetahui keterkaitan antara kearifan lokal dengan identitas nasional, tantangan kearifan lokal di era disrupsi, dan strategi menjaga eksistensi kearifan lokal di era disrupsi. Era disrupsi memberikan dampak negatif terhadap eksistensi kearifan lokal, karena banyak masyarakat khususnya pemuda meninggalkan kearifan lokal dan lebih tertarik dengan budaya dan nilai dari luar terutama yang bertentangan dengan Pancasila. Penelitian ini menggunakan pendekatan kualitatif dengan metode penelitian kepustakaan. Teknik pengumpulan data menggunakan dokumentasi, sedangkan analisis data yang digunakan ialah analisis konten. Kearifan lokal merupakan identitas nasional karena kearifan lokal yang berkembang di berbagai negara memiliki perbedaan khususnya terkait nilai, budaya, dan norma sehingga kearifan lokal yang berkembang di berbagai daerah di Indonesia merupakan identitas nasional bangsa Indonesia. Tantangan yang ditimbulkan era disrupsi terhadap eksistensi kearifan lokal di Indonesia ialah memudarnya sikap atau rasa bangga terhadap budaya lokal atau kearifan lokal, sehingga banyak sikap dan tindakan masyarakat khususnya pemuda yang meninggalkan kearifan lokal karena lebih tertarik dengan budaya asing khususnya yang bertentangan dengan Pancasila, seperti sikap individualis, pragmatis, oportunis, melakukan tindakan menyimpang melalui media sosial. Strategi yang harus dilakukan untuk menjaga eksistensi kearifan lokal di era disrupsi ialah 1) memaksimalkan peran pendidikan kewarganearaan di sekolah dengan cara menekankan pada pendidikan berbasis budaya lokal, 2) memegang erat dan mengimplementasikan nilai dan budaya yang berkembang di daerahnya masing-masing, dan 3) pemerintah bekerja sama dengan masyarakat melakukan pembinaan kepada masyarakat untuk menjaga eksistensi kearifan lokal, melalui kegiatan seperti bersih desa, gotong royong, pertunjukkan kesenian daerah dan lain sebagainya
The drop of the coherence of the lower kHz QPOs is also observed in XTE J1701-462

We investigate the quality factor and RMS amplitude of the lower kHz QPOs from XTE J1701-462, a unique X-ray source which was observed in both the so-called Z and atoll states. Correcting for the frequency drift of the QPO, we show that, as in all sources for which such a correction can be applied, the quality factor and RMS amplitude drops sharply above above a critical frequency. For XTE J1701-462 this frequency is estimated to be ~800 Hz, where the quality factor reaches a maximum of ~200 (e.g. a value consistent with the one observed from more classical systems, such as 4U~1636-536). Such a drop has been interpreted as the signature of the innermost stable circular orbit, and that interpretation is consistent with the observations we report here. The kHz QPOs in the Z state are much less coherent and lower amplitude than they are in the atoll state. We argue that the change of the QPO properties between the two source states is related to the change of the scale height of the accretion disk; a prediction of the toy model proposed by barret et al. (2007). As a by-product of our analysis, we also increased the significance of the upper kHz QPO detected in the atoll phase up to 4.8 sigma (single trial significance), and show that the frequency separation (266.5+/-13.1 Hz) is comparable with the one measured from simultaneous twin QPOs the Z phase.
Numerical Investigations on Slip Characteristics and Slip Onset Position in High-Loaded Backswept Centrifugal Impellers

This paper mainly investigates the effect of mass flow, blade turning and tip clearance size on the slip characteristics in the high-loaded backswept centrifugal impeller by numerical simulation. The numerical results show that the slip onset position mainly depends on the blade loading and the intensity of tip leakage flow. The mass-averaged slip onset position moves upstream but changes little with increased mass flow. The mass-averaged slip onset position is very close to the position of the peak value in the B2B blade loadings at the design condition. With increased exit blade angle, the mass-averaged slip onset position moves downstream and the mass-averaged slip factor increases. With increased tip clearance size, the mass-averaged slip onset position moves downstream first and then upstream. This study can supply some guidance to develop the slip onset position prediction model for high-loaded backswept centrifugal impellers.
Pyrethrum marc rates and intra-row spacing influence on selected soil chemical parameters and yield of bush bean (Phaseolus Vulgaris L.) grown on andosol under rainfed conditions

Bush bean is an important pulse crop that enriches the Rwandan diet and is a source of cash. This staple crop is widely grown in Rwanda. However, the improper spacing and inadequate application rates of organic inputs result in low yields. The purpose of this study was to evaluate the effect of intra-row-spacing and pymarc application rate on selected soil chemical parameters and bush bean (Phaseolus Vulgaris L) yield on andosol under rainfed conditions. The experiment included five pymarc rates with four replications in a randomized complete block design: P0(No fertilizer), P1(250 kg ha-1 of NPK), P2(10 t ha-1 of pymarc + 250 Kg ha-1 of NPK), P3(15 t ha-1 of pymarc + 250 Kg ha-1 of NPK) and P4(20 t ha-1 of pymarc + 250 Kg ha-1 of NPK) and 3 spacing levels: S1(40 cm x 15 cm), S2(40 cm x 20 cm) and S3(40 cm x 30 cm). The results indicated that a significant difference was found between treatments and their interactions except for pH (p<0.05). Regarding pymarc treatments, P4 contained greater amounts of organic C(5.30 %), total N(0.30 %), available P(56.70 ppm), available K(81.30 mg dm-3), exchangeable Ca(12.61 Cmol Kg-1) and Mg(5.0 Cmol Kg-1) at harvesting compared to P0 and P1. According to plant spacing, S3 held higher amounts of OC(4.85 %), av. P(55.15 %), av. K(60.94 mg dm-3), exch. Ca(11.0 Cmol Kg-1) and exch. Mg(3.6 Cmol Kg-1) than S1. There was an interaction effect of pymarc and spacing on measured soil chemical properties except for soil pH. The correlation analysis between nutrients was positive, highly significant (p<0.01), and varied from moderate to strong (0.40.7) except pH. The treatment with the highest bush bean yield was P2S1 with 3.03 t ha-1 and therefore it can be recommended to bush bean farmers of the volcanic highland region.
What do we really know about nominal classification systems

The problem of 'classification' is a general problem of life. Biology has shown that classification abilities are necessal)' for the survival of every organism. Human beings classify consciously. unconsciously and e\'en subconsciously in all situations. \Nhen we confrom a scientific problem, we try to solve it by first classifying the various parts of the problem. Therefore, the history of all branches of science is also a history of how these sciences have classified their research subject. 'Classification' always implies 'selection', too, because, as Koestler ([978: 20[) put it, our
CRYOCAPACITATION AND ITS ASSOCIATION WITH OXIDATIVE FEATURES IN CRYOPRESERVED BOVINE SPERMATOZOA

The goal of our research was to evaluate the impact of cryopreservation on the antioxidant activity, lipid peroxidation and protein carbonylation as well as its connection with the progress of cryocapacitation in bovine spermatozoa. As biological material we used semen obtained from 20 sexually mature Holstein bulls. Each ejaculate was divided into three equal aliquots as follows: the first part or control (CTRL) was incubated in physiological saline solution while the second part (CAP) was incubated in a capacitation medium at specific conditions. The third part of each sample was cryopreserved (CRYO) and stored in liquid nitrogen at -196°C for further analysis. The motility of spermatozoa was assessed with CASA (computer assisted sperm analysis), while the capacitation status was evaluated by the chlortetracycline (CTC) fluorescent staining. Total antioxidant capacity (TAC) and the level of lipid peroxidation (LPO) was measured with a combined spectro-fluoro-luminometer. The presence of protein oxidation was detected by the traditional DNPH (2,4-dinitrophenylhydrazine) method and evaluated spectrophotometrically. Based on our data, the motility was significantly decreased (P<0.0001; P<0.01) in the CRYO group against CAP and CTRL. There was a significant increase (P<0.01; P<0.05) of acrosome-reacted spermatozoa (AR-pattern) in the CRYO group when compared to CTRL and CAP, while TAC was statistically decreased (P<0.05) between the CRYO and CAP experimental group. In the case of protein oxidation and LPO, both parameters were significantly higher (P<0.0001) in the CRYO group when compared to CAP or CTRL. In summary, cryopreservation induces capacitation-like changes and promotes oxidative damage in frozen-thawed bovine spermatozoa.

Impact of CPAP Therapy on New Inflammation Biomarkers

Obstructive sleep apnea (OSA) is a common sleep disorder leading to increased risk of developing cardiovascular diseases (CVDs) by supporting a low-grade chronic inflammation as one of the pathological mechanisms. The continuous positive airway pressure (CPAP) device is used as an effective treatment for moderate and severe OSA. Neutrophil–lymphocyte ratio (NLR), platelet–lymphocyte ratio (PLR), white blood cell–mean platelet volume ratio (WMR), C-reactive protein–albumin ratio (CAR) and fibrinogen–albumin ratio (FAR) are new potential inflammatory biomarkers that are widely available and were shown to be possibly favorable screening or follow-up tools for moderate- or severe-grade OSA, as well as indirect indicators for cardiovascular risk. Our study evaluated the impact of CPAP therapy in patients with severe OSA and acceptable therapy adherence on NLR, PLR, WMR, FAR and CAR. Of 57 patients who were initially enrolled and had no exclusion criteria, 37 had a satisfactory CPAP adherence (usage of ≥4 h per night) after a minimum of 6 months of therapy. There was a statistically significant difference in NLR (2.122 ± 0.745 before therapy vs. 1.888 ± 0.735 after therapy) and FAR (86.445 ± 18.763 before therapy vs. 77.321 ± 19.133 after therapy) suggesting a positive effect of the CPAP therapy on chronic inflammatory states, thereby possibly reducing cardiovascular risk.
Combining ability and selection of wheat populations for a tropical environment

The selection of segregating populations with the potential for derived lines is essential for breeding programs. The present work analyzes the potential of tropical F2 wheat (Triticum aestivum L.) populations originated from complete diallel cross combinations. For this purpose, eight tropical wheat cultivars were combined in a complete diallel design in 2019 after F1 seeds were multiplied in a greenhouse and the seeds of 56 F2 populations, plus the eight parents, were evaluated in the field in Viçosa, MG, Brazil in the winter harvest of 2020 using a simple lattice design (8×8). The trait scores of (1) severity of tan spot (Pyrenophora tritici-repentis), (2) severity of wheat head blast (WHB) (Magnaporthe oryzae pathotype Triticum), (3) days to heading, (4) spike height, (5) and total grain weight of the plot were evaluated. We performed a diallel analysis using mixed models to obtain the effects of general combining ability (GCA), specific combining ability (SCA), and estimation of population genotypic values. The additive effect predominated for the control of all traits, except for spike height. There were greater GCA effects for the set of parental maternal plants. Heritability, in the narrow sense, ranged from 0.20 (blast) to 0.66 (heading). There was an effect of maternal GCA for all variables, while for paternal GCA the effect was only for days passed for head and total grain weight. Populations derived from the cultivars TBIO Aton, TBIO Ponteiro, and TBIO Sossego had lower disease severity, while the combinations from BRS 254, BRS 264, and BRS 394 had earlier maturation time. The most promising combinations to derive lines for the set of traits were BRS 254 × CD 1303, BRS 394 × TBIO Aton, TBIO Aton × BRS 254, CD 1303 × BRS 254, and CD 1303 × BRS 264.
Unsteady Mixed Convection Slip Flow around a Stretching Sheet in Porous Medium

The heat and mass transfer of unsteady MHD two-dimensional mixed convection boundary layer flow over an exponentially porous stretching sheet is presented in this paper. Multiple slip conditions, radiation, suction or blowing, heat generation or absorption along with magnetism and porous medium are incorporated. We reduce the leading equations which are partial differential equations into a family of ordinary differential equations that are non-linear using a set of similarity transformations. The resulting equations with coupled boundary conditions are solved numerically with the aid of bvp4c solver with MATLAB package. The impacts of several non-dimensional governing parameters on the flow fields such as velocity, temperature and concentration profiles along with friction coefficient, temperature gradient and concentration gradient are portrayed graphically and discussed in detail. The result in-dicates that the magnetic parameter decreases the skin friction coefficient. Thermal boundary layer thickness reduces with increasing radiation parameters and enhances with increasing Prandtl number. It is also observed that the thermal slip parameter depreciates the heat transfer rate and the mass slip parameter diminishes the mass transfer rate. A comparison has been made between the current results and the numerical results of previous studies and observed a very close good agreement.
Co-sensitization to the three non-homologous major cashew allergens Ana o 1, Ana o 2 and Ana o 3 is caused by IgE cross-reactivity.

BACKGROUND Cashew nuts often cause strong allergic reactions, even exceeding those of peanuts. Ana o 1 (vicilin), Ana o 2 (legumin) and Ana o 3 (2S albumin) are major cashew allergens. Co-sensitization to all three non-homologous cashew nut allergens has been observed. We hypothesize that this might be due to IgE cross-reactivity. METHODS IgE cross-inhibitions were performed with Ana o 1-3 using sera from cashew nut allergic patients. Related hazelnut allergens Cor a 11, 9 and 14 were used as controls. For comparison, IgE cross-reactivity between the hazelnut allergens was investigated using sera from hazelnut allergic patients. RESULTS Median percentages of cross-inhibitions between Ana o 1-3 were 84-99%. In comparison, medians of cross-inhibitions between hazelnut allergens were 33-62%. The IC50 values revealed the highest IgE affinity to Ana o 3 and Cor a 14. Hazelnut legumin Cor a 9 inhibited IgE-binding to Ana o 1, 2, and 3 with median percentages of 75%, 56%, and 48%, respectively. No cross-reactivity was observed between allergenic vicilins or between 2S albumins from cashew and hazelnut. In silico identified potentially cross-reactive peptides of Ana o 3 overlapped with previously reported IgE epitopes of all three allergens. CONCLUSIONS IgE with high affinity to Ana o 3 that cross-reacts with the other two major non-homologous cashew nut allergens might be responsible for the high allergenic potency of cashew nut. These cross-reactive IgE comprises the major fraction of specific IgE in cashew allergic patients, and might be responsible for cross-reactivity between unrelated tree nuts.
Coherent spin dynamics of electrons and holes in semiconductor quantum wells and quantum dots under periodical optical excitation: resonant spin amplification versus spin mode-locking

The coherent spin dynamics of resident carriers, electrons and holes, in semiconductor quantum structures is studied by periodical optical excitation using short laser pulses and in an external magnetic field. The generation and dephasing of spin polarization in an ensemble of carrier spins, for which the relaxation time of individual spins exceeds the repetition period of the laser pulses, are analyzed theoretically. Spin polarization accumulation is manifested either as resonant spin amplification or as mode-locking of carrier spin coherences. It is shown that both regimes have the same origin, while their appearance is determined by the optical pump power and the spread of spin precession frequencies in the ensemble.
