The Effect of Mangosteen Rind Extract (Garcinia mangostana L.) Toward Stress Oxidative Parameter, Leukocytes, Leukocytes Type Counts on Male Rats (Rattus norvegicus) with Excessive Physical Activity

BACKGROUND: Excessive and heavy physical activity could lead to the oxidative stress in the body. This condition can affect several blood parameters such as malondialdehyde (MDA), glutathione peroxidase (GPx), leukocytes, and its type counts. One way to overcome the effects of oxidative stress due to strenuous physical activity is by giving natural antioxidants. Mangosteen rind (Garcinia mangostana L.) contains considerable antioxidants, namely, xanthones and procyanidin. AIM: This research aimed to investigate the effect of mangosteen rind extract (MRE) on oxidative stress parameters, leukocyte count, and leukocyte count in male rats (Rattus norvegicus) that received excessive physical activity. METHODS: This study was purely experimental research with a post-test only control group design, using 29 white rats (R. norvegicus) as experimental animals, which were divided into four groups. The first group (P1) received distilled water and the other group received MRE at a dose of 50 mg/KgBW (Body Weight) (P2), 100 mg/KgBW (P3), and 200 mg/KgBW (P4) for 3 weeks, respectively. Swimming as a physical activity was carried out 3 times a week in all groups. Examination of leukocyte count and species was carried out on the last day of treatment after the rats swam to fatigue. RESULTS: MDA levels did not decrease significantly while GPx activity increased significantly. Moreover, the average leukocytes and lymphocytes showed a decrease but not significant. A significant decrease in the percentage of neutrophils and basophils was obtained by P4 group compared to others. In addition, a significant decrease in the average percentage of eosinophils for P3 and P4 groups was obtained. Furthermore, P3 and P4 group exhibit significant increase of the average percentage of monocytes. CONCLUSION: MRE as an antioxidant affects the levels of neutrophils, basophils, eosinophils, and monocytes but not in MDA, GPx, leukocytes, and lymphocytes.
The Determination of the Liquid Immiscibility Boundaries of the Lithium-Sodium and Thallium-Selenium Systems by the Liquid Density Method

Abstract The immiscibility boundaries and monotectic temperatures of the lithium-sodium and thallium-selenium systems were determined by techniques using density-temperature and density-composition isotherms. The immiscibility boundary of the lithium-sodium system was found to extend from 10.5 to 96 weight percent sodium at the monotectic temperature, 170°±1°C. The critical solution (consolute) temperature was found to be 306°±1°C. The thallium-rich immiscibility region of the thallium-selenium system has a consolute temperature of 750°±1°C and a monotectic isothermal of 380°±1°C extending over the composition range 0.1–32.9 atom percent selenium. The second immiscibility region in this system was found to have a consolute temperature of 454° ± 1°C and a monotectic isothermal of 201° ± 1°C. The latter extends between the composition limits 77–99.9 atom percent selenium.
Implicações nutricionais e sensoriais da polpa e casca de baru (Dipterix Alata vog.) na elaboração de pães

Interest in new sources of nutrients and the need of preserving native species of the savanna, through their valorization, motivates the study of their potential for supplementing products. The objective of this study was to investigate the feasibility of using the peel and pulp of the baru to develop sliced bread and the consequent nutritional and sensory implications. In the process of developing whole wheat sliced bread, oat bran was replaced for baru's peel and pulp using four proportions (25, 50, 75, and 100%). The analysis of the chemical composition of baru's peel and pulp resulted in 21.05% moisture, 65.01% carbohydrates, 3.30% lipids, 4.45% protein, 1.79% ash, and 4.39% crude fiber. All samples were accepted considering the attributes appearance, texture, and flavor. They were considered low in total fat (2.18%), showed no significant difference regarding the content of protein (13.59%) and moisture (34.54%). It presented an average content of carbohydrate of 41.90 and 1.76% of ash. There was an increase of up to 58.20% in the total content of the dietary fiber with the increase of the proportion of baru's peel and pulp. The results indicate that the peel and pulp of baru viable ingredients in the technology application to prepare whole wheat sliced bread improving nutritional characteristics and sensory attributes.
Ibero-American higher education institutions facing COVID-19

ABSTRACT The article aims to identify the variables associated with the perception that the members of the educational community (professors and students) from higher education institutions in Ibero-America during, the first weeks of the COVID-19 pandemic. The study based on an Internet applied survey from April 6th to 20th of 2020, with 771 respondents (1-α = 95% and e = 3,5) from Argentina, Colombia, Chile, Spain, Mexico, and Puerto Rico. The main results reveal how the positive assessment of higher institutions depends on how professors and students perceived the risk of infection and other external variables (non-institutional) such as their previous experience in virtual environments. To a lesser degree, during the study period, professors and students with the most negative states of mind expressed more significant difficulties in managing academic activities. Therefore, it recommends that higher education institutions in Ibero-American work improve communication channels and implement programs of accompaniment that foster resiliency, starting from the construction of institutional bonds and strengthening the socioemotional skills of both professors and students.
On negative induced polarization in frequency domain measurements

Induced polarization (IP) has been widely used to non-invasively characterize electrical conduction and polarization in the subsurface resulting from an applied electric field. Earth materials exhibit a lossy capacitance defined by a negative intrinsic phase in frequency-domain IP (FDIP) or a positive intrinsic chargeability in time-domain IP (TDIP). However, error-free positive apparent phase or negative apparent chargeability (i.e. negative IP effects) can occur in IP measurements over heterogeneous media. While negative IP effects in TDIP data sets have been discussed, no studies have addressed this topic in detail for FDIP measurements. We describe theory and numerical modelling to explain the origin of negative IP effects in FDIP measurements. A positive apparent phase may occur when a relatively high polarizability feature falls into negative sensitivity zones of complex resistivity measurements. The polarity of the apparent phase is determined by the distribution of subsurface intrinsic phase and resistivity, with the resistivity impacting the apparent phase polarity via its control on the sensitivity distribution. A physical explanation for the occurrence of positive apparent phase data is provided by an electric circuit model representing a four-electrode measurement. We also show that the apparent phase polarity will be frequency dependent when resistivity changes significantly with frequency (i.e. in the presence of significant IP effects). Consequently, negative IP effects manifest themselves in the shape of apparent phase spectra recorded with multifrequency (spectral IP) data sets. Our results imply that positive apparent phase measurements should be anticipated and should be retained during inversion and interpretation of single frequency and spectral IP data sets.

The Fundamental Physics of de Broglie’s Waves, Part One

We uphold a general viewpoint that the ideas have their own ‘objective’ dynamics, that is a dynamics independent of personalities. Every now and then, the ideas are accessible to individuals. When it comes to social expression, though, it is only a genius, among individuals, who can reach such an accessible idea as ultimate truth, even to the point where he/she succeeds to casting it into proper words, available to society at large. Beyond those words no one can ‘rationalize’, not even the genius himself. We illustrate this observation with Erwin Schrodinger’s interpretation of the wave function introduced by him to common knowledge, which has been cast into proper words by another genius, Richard Feynman, who, nevertheless, honestly acknowledged mistrusting that interpretation. In fact, Feynman always openly admitted, and effectively exercised the probabilistic interpretation of Max Born. To wit, it is guided by this kind of interpretation, that he has built the well-known version of wave mechanics, which is based entirely on the concept of probability. We argue that Feynman was actually right on both accounts – Schrodinger’s and Born’s interpretations – and show here why and how, thus revealing a few missing points in the contemporary natural philosophy. The whole argument, and the accompanying illustration, stands completely by the words of still another genius of modern physics: Louis de Broglie, whose physics is documented and developed in the present work. The construction of this physics gives us the opportunity of a historical review of significant moments of the physical knowledge.
Comparative Measurement of the PPG Signal on Different Human Body Positions by Sensors Working in Reflexive and Transmission Modes

The paper deals with the photoplethysmographic (PPG) optical sensor usage for non-invasive acquisition of vital information about the cardiovascular system from different parts of the human skin surface. Finger-ring and ear-clip realizations of the transmission-type PPG sensor were tested first. For the next PPG signal recording, the reflection PPG sensor was placed on fingers and on a wrist. PPG signal properties were described by energetic and temporal parameters and their statistical parameters together with determined instantaneous heart rate values. Our final aim was to find conditions, limitations, and recommendations for development of a wearable PPG sensor working in a magnetic field environment.
Electrochemical Solar Cell Based on the d-Band Semiconductor Tungsten-Diselenide

In a search for corrosion resistent electrode materials for electrochemical solar cells the covalent, layered semiconductor WSe2, has been investigated. Its photoactivity in the visible spectral region (band gap 1.57 eV) involves d-d electron transitions which do not lead to an immediate photocorrosien. An energetically favourable energy band position makes it possible to operate p-type material as photocathodes for energy conversion. Photocell outputs in the order of 15 mA/cm2 and 0.5 V were obtained in 100 mW/cm2 illumination (Xenon-lamp). It is shown that the produced photovoltage is not systematically dependent on the redox potential of the redox agents but influenced by their chemical reactivity due to a specific interaction with the electrode surface. Auf der Suche nach korrosionsfesten Halbleiterelektroden fur elektrochemische Solarzellen ist das Schichtgittermaterial WSe2 untersucht worden. Photonenabsorption im sichtbaren Spektralbereich (Bandabstand 1,57 eV) bewirkt in diesem Halbleiter d-d-Elektronenubergange, die nicht zu einer sofortigen Photokorrosion der Elektrode fuhren. Die energetisch gunstige Position der Bandkanten erlaubt es, p-dotiertes Material als Photokathode fur elektrochemische Energieumwandlung zu benutzen. Bei Belichtung mit 100 mW/cm2 (Xenon-lampe) gab die Photozelle bis zu 15 mA/cm2 Photostrom und bis zu 0,5 V Photospannung ab. Es stellte sich heraus, das die Photospannung nicht in systematischer Weise vom Redoxpotential des Redoxelektrolyten abhangt, sondern von dessen chemischer Reaktivitat, die hier durch eine spezifische Wechselwirkung mit der Elektrodenoberflache beeinflust wird.
Facile Synthesis of Activated Carbon-Supported Porous Manganese Oxide via in situ Reduction of Permanganate for Ozone Decomposition

Lichen-like porous manganese oxides (MnOx) with birnessite-type structure, which were assembled with curled nanosheets (less than 10 nm in thickness), were deposited in situ on the surface of activated carbon (AC) via facile reduction of permanganate by AC, and were tested for the decomposition of ozone, a common air pollutant. Despite the low Mn loading (typically 0.04%–0.14%), the as-synthesized MnOx/AC catalysts exhibited high catalytic activity and stability for ozone decomposition at room temperature and high relative humidity, which can be attributed to the enrichment of the Mn element on the catalyst surface and a well-organized porous surface morphology of MnOx.
On the adoption of innovation in the housing sector

Innovation adoption is of utmost importance for company survival. That is why it is important to develop a thorough understanding of this research domain and the themes it encapsulates. Since the early work of Everett Rogers, the adoption of innovation literature has attracted considerable attention and has continued to grow rapidly, resulting in a large but fragmented body of literature. The goal of this study is to provide a coherent overview of the theoretical cornerstones as well as recent research trends in the innovation adoption literature. To this end, we conducted a bibliometric review and performed bibliographic coupling and co-citation analysis. First, based on co-citation analysis, we illustrate that innovation adoption research is built on four theoretical cornerstones including: institutional theory; theory of reasoned action; theory concerning the determinants of adoption, and; diffusion theory. Second, bibliographic coupling was used to assess the current research trends. This review is the first to identify thematic areas in an exhaustive manner revealing five clusters of thematic related publications or “research trends”: determinants of IT adoption; adoption of technological standards; organizational rationales associated with adoption; modelling diffusion, and; adoption of agricultural innovations. We conclude this review with the limitations and future research orientations in the field of innovation adoption. 10.Van Oorschot, J.A. W.H. , Hofman, E. , & Halman, J.I. M. (2018).

Mechanism of NO2 detection in carbon nanotube field effect transistor chemical sensors

We report an experimental method that clearly determines the sensing mechanism of carbon-nanotube field effect transistors. The nanotube/electrode contacts are covered with a thick and long passivation layer that hinders their exposure to chemicals in a controlled fashion, leaving only the midsection of the nanotube exposed. In the case of nitrogen dioxide, a considerably delayed response is fully consistent with the diffusion of the gas through the passivation layer. The results clearly indicate that nitrogen dioxide detection is due to changes at the interfaces between the nanotube and the electrodes and not to molecules adsorbed on the nanotube surface.
Intravitreal Use of a Bone Marrow Mononuclear Fraction (BMMF) Containing CD34+ Cells in Patients with Stargardt Type Macular Dystrophy

To assess the therapeutic potential and the safety of intravitreous use of a bone marrow mononuclear fraction (BMMF) containing CD34+ cells in patients with Stargardt type macular dystrophy. The study was conducted on 10 patients with Stargardt dystrophy with worse eye visual acuity ≤ 20/125. A bone marrow aspirate was obtained from all patients, and after processing in the cell therapy center (CTC), 0.1 ml of the intravitreous BMMF suspension was injected into the eye with worse visual acuity. A sham injection was performed in the contralateral eye. The patients were evaluated at baseline and one, three, and six months after the injection. All of them were submitted to measurement of best corrected visual acuity (BCVA), microperimetry, multifocal electroretinography (mfERG) and full field electroretinography (ffERG), autofluorescence (AF), and optical coherence tomography (OCT). Fluorescein angiography was also performed before and six months after the injection. All patients completed the six-month period of evaluation. Mean visual acuity of the treated eye was 1.1 logMAR (20/250) before intravitreous (IV) injection, 0.96 logMAR (20/200+2) one month after injection, and 0.92 logMAR (20/160-1) 3 months after injection. In the untreated eye, mean VA was 1.0 logMAR (20/200) at baseline and 0.96 logMAR (20/200+2) and 0.94 logMAR (20/160-2) one and three months after injection, respectively. In the treated group, VA at baseline ranged from best acuity of 20/125-1 to worst acuity of 20/640+2, going through 20/100+2 and 20/400 during the first month. In the untreated group, BCVA ranged from 20/100+2 to 20/400 at baseline and from 20/100 to 20/400 after one month. The results for the treated group differed significantly at all follow-up times, whereas no significant difference was observed in the untreated group. Regarding the mean sensitivity of microperimetry, although there was improvement throughout all months, a significant difference occurred only during the first month. In the untreated eye, there was no significant difference in any analysis. Angiofluoresceinography did not reveal neovessel formation or tumor growth. The remaining exams were used in order to aid the diagnosis. The results indicate that the use of intravitreous BMMF in patients with Stargardt dystrophy is safe and is associated with a discrete improvement of BCVA and microperimetry in the treated eye compared to the untreated one.
Farmer Empowerment in The Application Intercropping Technology of Chili Pepper (Capsicum Annum L.) and Cauliflower (Brassica Oleracea) in Bangodua District, Indramayu Regency

This study aims to describe the empowerment of farmers in intercropping technology implementation, analyze the empowerment of farmers in the application of intercropping technology, and develop counseling strategies to increase the empowerment of farmers in the application of intercropping technology. Data were analyzed descriptively quantitatively, using multiple linear regression and determining extension strategies to increase farmer empowerment using SWOT analysis. The results showed that most farmers were of productive age (15-64 years old) with the dominant level of education in the low category (elementary / junior high) have monthly income (<Rp 4,000,000) but have experience in farming with the experienced category (11- 16 years old). Factors that affect the empowerment of farmers in intercropping technology implementation are the level of education, farming experience, the intensity of empowerment, and information availability while the factors that have no effect such as age, income level, and social physical environment. The strategy used to improve empowerment uses SWOT analysis so that the strategies. The need to do is increase innovations adoption in terms of the benefits of intercropping technology that can stabilize the harvest price accumulation. Information literacy can utilize demographic bonuses in the form of many productive ages through online e-marketing. It aligns the development of information with the synergy of cooperation between competing factors related to maximizing the potential of farm products in the field.
A Minimal Flow Unit of the Logarithmic Layer in the Absence of Near-Wall Eddies and Large Scales

In the vicinity of walls, turbulent flows are found to be highly organized, consisting of streamwise rolls and lowand high-speed streaks (Klebanoff et al. 1962; Kline et al. 1967; Smith & Metzler 1983; Blackwelder & Eckelmann 1979; Johansson et al. 1987) that are involved in a quasi-periodic regeneration cycle (Robinson 1991; Panton 2001; Adrian 2007; Smits et al. 2011; Jiménez 2018). Important progress regarding the study of this regeneration cycle was made using the “minimal flow unit” approach, which indicated that buffer layer streaks can self-sustain even when motions at larger scales are inhibited and that their existence, therefore, relies on an autonomous process (Jiménez & Moin 1991). The observation that the buffer and viscous layers of wall-bounded flows can be simulated in periodic boxes of minimal dimensions has been useful in understanding wall turbulence since it enables the study of individual flow features in isolation from their mutual interactions. The minimal simulation boxes for the buffer layer of turbulent channels have been extended to the logarithmic (log) and outer regions, where they contain a segment of streamwise velocity streak, and a vortex cluster (or streamwise roll) (Flores & Jiménez 2010). Contrary to the minimal flow unit for the buffer layer, intermediate flow units allow for self-sustained motions of scales smaller than the flow unit extension. While the minimal flow unit for log layers demonstrates that a similar but more disorganized scenario occurs for the log layer (Flores & Jiménez 2010; Lozano-Durán et al. 2012; Lozano-Durán & Jiménez 2014; Hwang & Bengana 2016; Cossu & Hwang 2017; LozanoDurán et al. 2019), and it is known that destroying the dynamics of the buffer layer has essentially no influence over the statistics of the outer flow (Townsend 1976; Perry & Abell 1977; Jiménez 2004; Bakken et al. 2005; Flores & Jiménez 2006; Flores et al. 2007; Mizuno & Jiménez 2013; Chung et al. 2014; Lozano-Durán & Bae 2019a), the larger boxes isolate more complicated, fully multiscale structures that reach from the wall farther into the core flow, making it harder to identify individual flow features to be studied as in the buffer-layer case. Large-eddy simulations (LES) with the static Smagorinsky model (Smagorinsky 1963) have been used in an attempt to isolate larger structures in the log region from the near-wall cycle and from the background smaller scales in turbulent channel (Hwang & Cossu 2010, 2011; Hwang & Bengana 2016) and plane Couette (Rawat et al. 2015) flows. This approach, termed overdamped LES, is based on the idea that by increasing the Smagorinsky parameter, an increasing range of small-scale structures is accounted for by the subgrid-scale model, whereas large structures are resolved by the LES grid (Cossu & Hwang 2017). However, recent findings suggest that overdamped LES represent
