Intensity of muon bundles according to the NEVOD-DECOR cosmic ray experiment

Data of NEVOD-DECOR experiment on investigations of inclined cosmic ray muon bundles for a long time period (May 2012 – May 2020) are presented. Their comparison with the results of calculations based on simulations of extensive air shower hadron and muon components is carried out. The analysis showed that the observed intensity of muon bundles at primary particle energies of about 1018 eV and higher can be compatible with the expectation only under the assumption of an extremely heavy mass composition of cosmic rays. On the contrary, measurements of the depth of the shower maximum in the atmosphere in the experiments using air fluorescence technique, favour a light mass composition of primary cosmic rays at these energies.

Soil fertility evaluation of an area is an important aspect in the context of sustainable agriculture production. In the present investigation KVK, Palem farm was selected in the district Nagarkurnool of Telangana and studied physico-chemical, available macro and micronutrient status using Nutrient Index approach made with the study of 60 surface soil samples and were analyzed for pH, Electrical Conductivity (EC), Organic Carbon (OC), Nitrogen (N), Phosphorus (P), Potassium (K) and micronutrients (Fe, Mn, Cu and Zn). Study results indicated that a major proportion of area soils are neutral (62.08%) and non-saline (100%). The whole study area was low in organic carbon content, ranging from 0.40 to 0.45 with a mean of 0.42%, and available nitrogen also low in the entire study area varied from 150.53 to 188.16 kg ha-1 with a mean value of 165.67 kg ha-1. The percent distribution of available P varied from medium to high status (34.48 and 72.41%), where available K was categorized under high (100%) status. With regard to micronutrients, the soils were predominantly deficient in Zn (24.13%) followed by Fe (20.68%) and Mn (6.89%).
The Portraits of Digital Literacy Awareness Amid Covid-19 Pandemic

Digital literacy is a familiar topic in this millennial era with various digital media with open access that can be used anytime and anywhere. Based on this, this study aims to describe the digital literacy awareness of a family during the Covid-19 pandemic as a phenomenon that is currently being discussed. This study uses a type of phenomenology with data collection techniques through observation and interviews. The data extracted included knowledge assembly, utilization of digital sources and media, access and hypertextual navigation, content evaluation of the research subject, namely a family of various ages. The results showed that digital literacy awareness varied greatly from the media, access patterns, and evaluations carried out by each respondent in accessing information. It can be concluded that digital literacy awareness is still not optimal according to the indicators used and still needs to be improved, especially in building critical thinking patterns and utilizing technology as part of digital literacy.
Spectrophotometric monitoring of nitrite in seawater after liquid microextraction of its derivative with 2,3-diaminonaphthalene

A simple dispersive liquid–liquid microextraction based on solidification of floating organic droplets coupled with spectrophotometric detection was developed for the determination of nitrite in Chabahar Bay seawater. In the preparation procedure, 2,3-diaminonaphthalene as derivatization reagent reacts with nitrite in acidic medium to form a photometric center of 1-[H]-naphthotriazole (NAT). Product material (NAT) was extracted by dispersive liquid–liquid microextraction with 1-dodecanol as extraction solvent and after centrifugation, the floated droplet was solidified in an ice bath and was easily removed for analysis at λ max = 358 nm. Several important factors affecting the microextraction efficiency were optimized in artificial seawater as a best simulation media. Under the optimum conditions, the absorbance of NAT was linear with nitrite concentrations ranging from 0.1 to 11 μg/mL in seawater. Figures of merit of method such as enrichment factor (52), limit of detection (0.094 μg/mL), and repeatability (N = 6, %RSD = % 5) were evaluated as appropriate. Determination of nitrite in Chabahar coastal zone showed that nitrite concentration varied in the range of 0.77–1.76 μg/mL with an increase of concentration from South to the North of Bay.
Human RF-EMF Exposure Assessment Due to Access Point in Incoming 5G Indoor Scenario

The study aimed at expanding the knowledge about the assessment of radio-frequency electromagnetic fields (RF-EMF) exposure, considering the novelties introduced by the incoming 5G networks. Specifically, a possible future case of indoor exposure scenario is investigated, where the presence of a 5G access point (AP) in a room is simulated. The AP was modelled by two different indoor uniform planar array (UPA) antennas at 3.7 GHz and at 14 GHz, to evaluate how the beamforming and the higher frequency use could impact the exposure levels. Different scenarios were evaluated, considering the maximum antenna gain, two different human computational models, an adult model and a child one, and by varying the distance and the orientation between the UPA antenna and the two models head. All the simulations were conducted using the Sim4Life platform and in particular the exposure levels were expressed by the specific absorption rate averaged on 10 g of tissue (<inline-formula><tex-math notation="LaTeX">$SA{R_{10g}})$</tex-math></inline-formula>, which was analyzed for the skin and for some specific tissues. The work underlined that the highest <inline-formula><tex-math notation="LaTeX">$SA{R_{10g}}\ $</tex-math></inline-formula>values were obtained in the head area for all scenarios, with the skin <inline-formula><tex-math notation="LaTeX">$SA{R_{10g}}$</tex-math></inline-formula> highest peaks when the UPA is placed laterally to the human model (195.73 mW/kg and 223.29 mW/kg for the adult and child model, respectively, for 100 mW input power). Furthermore, the work permitted to highlight that the <inline-formula><tex-math notation="LaTeX">$SA{R_{10g}}\ $</tex-math></inline-formula>exposure levels are slightly higher for the child model, compared to the adult one and that the distance between the UPA antenna and the human models could greatly lower the <inline-formula><tex-math notation="LaTeX">$SA{R_{10g}}$</tex-math></inline-formula> levels. At last, it was found that the <inline-formula><tex-math notation="LaTeX">$SA{R_{10g}}$</tex-math></inline-formula> exposure levels obtained with the UPA antenna at 14 GHz were lower than the ones at 3.7 GHz, although further investigations will be necessary.
High-pressure crystal chemistry of KAlSi3O8 hollandite

A high-pressure single crystal XRD study of KAlSi 3 O 8 with the tetragonal hollandite structure has been completed to 4.47 GPa. The a axis is approximately twice as compressible as c, so c/a increases with pressure. This anisotropy is similar to that of the structurally related mineral stishovite, though hollandite is approximately 53% more compressible along both axes. The relative incompressibility of the c axis can be explained by the strong cation to cation repulsive forces across the shared octahedral edge in the double chain.
A Multi-disciplinary Mixed-Methods Study of Group Dynamics in Active Learning Space

Active learning space emerged at the turn of the twenty-first century. The active learning space design represents not only an overhaul of traditional classrooms’ physical appearances but also reflects a paradigm shift from teacher-centered learning to student-centered learning. Current available research mainly focused on student academic performance as well as student and faculty perceptions. No research has been conducted to investigate interactions at the student level to find out what interactions are taking place in the active learning space and how they affect student learning. This study employed a sequential exploratory mixed-methods design inquiring into student learning in an active learning space first through student focus group discussions and then with an online student survey. The major themes emerged from the focus group discussions were utilized to develop the online survey. The purpose of this survey was to cross-validate qualitative outcomes and further seek answers to unanswered questions triggered by qualitative findings. The qualitative data indicated that the spatial equity in the active learning space put students in positive mindsets and induced active classroom participation. The interconnected screens made it easy for students to view class content and collaborate with peers. The group work conducted in the space fostered mutual learning, promoted learning accountability and improved peer relations. The quantitative survey data on group dynamics validated and reinforced qualitative findings. This paper will help educators better understand student behaviors in the active learning space and better design space-appropriate pedagogical strategies.
Happiness Among Urban Poor Filipino Families

Filipinos are generally observed to display happiness despite the experience of poverty. However, limited researches have been done to support or explain such observation. The purpose of the study was to examine the level of happiness among selected Filipino families who were living below the poverty line. The study also identified the families’ sources of happiness and the actions they take to experience happiness. A qualitative research design was used. Twenty urban poor two-parent families were the subjects of the study. The Family Subjective Happiness Scale was administered to the families to determine their level of happiness. In depth-interviews were used to examine the families' sources of happiness and the actions they take to be happy. The data were analyzed using descriptive statistics and thematic analysis. The results showed that most of the poor families were either happy or very happy. The primary sources of happiness of the families include good family relationship, family togetherness, having children, faith in God, and good health. On the other hand, learning to be content, finding ways to solve their problems, engaging in leisure activities, and developing optimism were the things that the families do to achieve or experience happiness. Despite being poor, the families were happy mainly because they have close family relationships and are contented with their lives. The study provided valuable contribution to understanding why Filipino families show happiness despite poverty.

Oncocytic lipoadenoma of parotid gland with sebaceous differentiation

Oncocytic lipoadenoma a rare benign neoplasm of salivary gland was first described by Hirokawa et al in submandibular gland. We report a case of oncocytic lipoadenoma (oncocytic sialolipoma) in a 69 year old male who presented with an asymptomatic mass in right parotid region for the past 3 months. Grossly the lesion was well encapsulated with homogenous mahogany brown with focal grey yellow areas. Microscopically the lesion was completely encapsulated and showed an intimate admixture of oncocytes and mature adipocytes in almost equal proportion, with areas of focal sebaceous differentiation. Keywords: Salivary gland, Oncocytes, Oncocytic lipoadenoma.
Electromagnetic Fields Radiated by Lightning Return Stroke Over Lossy Ground With Rock Formation

Electromagnetic fields radiated by a lightning return stroke over lossy ground are calculated by finite difference time domain method in a two-dimensional cylindrical coordinate system. The considered ground model contains a rock formation for which four different geometries are defined: <italic>rectangle</italic>, <italic>triangle</italic>, <italic>circle,</italic> and <italic>random</italic>. Two electrical conductivities that are very low and very high compared to the conductivity of the ground are defined for the rock formation. Different scenarios are examined by computing horizontal electric field <inline-formula><tex-math notation="LaTeX">${{\boldsymbol{E}}_{\boldsymbol{r}}}$</tex-math></inline-formula>, vertical electric field <inline-formula><tex-math notation="LaTeX">${{\boldsymbol{E}}_{\boldsymbol{z}}}$</tex-math></inline-formula>, and azimuthal magnetic field <inline-formula><tex-math notation="LaTeX">${{\boldsymbol{H}}_{\boldsymbol{\varphi }}}$</tex-math></inline-formula> for both conductivities. In addition to the effect of different geometries, effects of spatial averaging, changing position of rock, different return stroke propagation speeds, observation points at different heights and different horizontal range distances are investigated adopting both first and subsequent return stroke currents as the source. The results show that <inline-formula><tex-math notation="LaTeX">${{\boldsymbol{E}}_{\boldsymbol{z}}}$</tex-math></inline-formula> and <inline-formula><tex-math notation="LaTeX">${{\boldsymbol{H}}_{\boldsymbol{\varphi }}}$</tex-math></inline-formula> fields are not much affected by geometry and conductivity change. However, for <inline-formula><tex-math notation="LaTeX">${{\boldsymbol{E}}_{\boldsymbol{r}}}$</tex-math></inline-formula> component, performances of <italic>rectangle</italic> and <italic>triangle</italic> geometries are close to each other and <italic>random</italic> one shows closest performance to that of the case when there is no rock inside the ground. On the other hand, the field values decrease as the rock conductivity increases for both stroke types.
Arene ruthenium(II) complexes with chalcone, aminoantipyrine and aminopyrimidine based ligands: synthesis, structure and preliminary evaluation of anti-leukemia activity

A series of arene ruthenium(II) (Ru) complexes with N-monodentate (AAP) and N,O- and N,N-bidentate chelating ligands (AAPS, ADABS, AAPPA and P2P) have been synthesized and evaluated for preliminary antileukemia activity. Single crystal X-ray studies of AAP-Ru, ADABS-Ru and P2P-Ru indicates that Ru(II) adopted a typical “three-leg piano-stool” geometry with pseudo-tetrahedral (AAP-Ru) and quasi-octahedral arrangements (ADABS-Ru and P2P-Ru). Supramolecular interactions (C–H⋯Cl, N–H⋯Cl and π–π) in the crystal lattice of AAP-Ru and ADABS-Ru resulted in a dimeric structure whereas P2P-Ru showed a supramolecular 1D chain. Importantly, preliminary in vitro anticancer activities for Ru-arene complexes have been evaluated against K562 (human chronic myeloid leukemia cell line) by means of MTT assay that showed strong anti-leukemic activity for AAPS-Ru (IC50 = 12.46 ± 0.47 μM) and P2P-Ru (IC50 = 11.8 ± 0.49 μM). The mechanistic studies indicated reactive oxygen species (ROS) mediated selective leukemic cells death without affecting the normal cells by AAPS-Ru. The initiation of apoptosis by AAPS-Ru treatment, particularly TNF-α induced cell death, was confirmed by pre-treatment with a selective TNF-α inhibitor.
The dynamics of Arthropod diversity and abundance in rice field ecosystem in Central Lombok, Indonesia

Abstract. Thei RSP, Abadi AL, Mudjiono G, Suprayogo D. 2020. The dynamics of Arthropod diversity and abundance in rice field ecosystem in Central Lombok, Indonesia. Biodiversitas 21: 5850-5857. Arthropods have roles as pests, decomposers, pollinators, and natural enemies of pests. Natural enemies play a vital role in pest population control by predation or parasitism. A study of the arthropod community in the rice field ecosystem was conducted in Central Lombok, Indonesia from December 2009 to March 2010 in order to elucidate the composition, structure, and dynamic diversity of arthropods present. Arthropod sampling was done by pitfall traps, yellow pan traps, and insect net. Arthropod dynamic diversity, especially of natural enemies, was determined by diversity index, dominance index, evenness analysis, and pictorial analysis. Based on taxonomical perspective, as many as 98 arthropod species were found, including 85 insect species from 59 families and 9 orders; and 13 spider species in 6 families. Based on the ecological functions, predator arthropods were the most common (33 species, dominated by spiders), but the phytophage arthropods had the most species richness (49.34%). A high Shannon index (3.18) and Pilou index (0.7) indicated dominant arthropods in the ecosystem. Arthropod species richness and diversity increased alongside rice development and decreased after harvest.

Exercise Training of Secreted Protein Acidic and Rich in Cysteine (Sparc) KO Mice Suggests That Exercise-Induced Muscle Phenotype Changes Are SPARC-Dependent

We previously identified secreted protein acidic and rich in cysteine (Sparc) as an exercise-induced gene in young and elderly individuals. Via this animal experiment, we aim to identify selected implications of SPARC mainly within the muscle in the contexts of exercise. Mice were divided into eight groups based on three variables (age, genotype and exercise): Old (O) or young (Y) × Sparc knock-out (KO) or wild-type (WT) × sedentary (Sed) or exercise (Ex). The exercised groups were trained for 12 weeks at the lactate threshold (LT) speed (including 4 weeks of adaptation period) and all mice were sacrificed afterwards. Body and selected tissues were weighed, and lactate levels in different conditions measured. Expression of skeletal muscle (SM) collagen type I alpha 1 chain (COL1A1) and mitochondrially encoded cytochrome c oxidase I (MT-CO1) in addition to SM strength (grip power) were also measured. Ageing increased the body and white adipose tissue (WAT) weights but decreased SM weight percentage (to body weight) and MT-CO1 expression (in WT). Exercise increased SM COL1A1 in WT mice and MT-CO1 expression, as well as weight percentage of the tibialis anterior muscle, and decreased WAT weight (trend). Compared to WT mice, Sparc KO mice had lower body, muscle and WAT weights, with a decrease in SM MT-CO1 and COL1A1 expression with no genotype effect on lactate levels in all our blood lactate measures. Sparc KO effects on body composition, adiposity and metabolic patterns are toward a reduced WAT and body weight, but with a negative metabolic and functional phenotype of SM. Whereas such negative effects on SM are worsened with ageing, they are relatively improved by exercise. Importantly, our data suggest that the exercise-induced changes in the SM phenotype, in terms of increased performance (metabolic, strength and development), including lactate-induced changes, are SPARC-dependent.
