Participation in School Processes and Practices: The case of an Arab School in Israel

School leadership can play an important role in leading change in the traditional patriarchal hierarchical cultures of developing societies. One way in which the leadership can introduce greater democracy is by increasing staff and students’ participation in school decision-making. This subject has not been widely studied in developing societies and very little research has related to staff/student participation in Arab schools in Israel. The present pilot casestudy in an Arab senior high school aimed to clarify the extent and quality of teachers’ and students’ participation in educational and administrative school processes and practices. A qualitative methodology employed interviews with two teachers and three students, focusing on their experiences, concerns and aspirations. The findings revealed that both teachers and students were aware of the concept of participation in school decision-making and in their school’s daily life. However, and despite this awareness, not all the participants have the opportunity to practice this involvement due to different obstacles such as time constraints, curriculum demands and the apparent inability or unwillingness of school leadership to facilitate collaboration between teachers and students and their involvement in decision-making. It is concluded that there is a need for empathetic educators’-students’ dialogue, a need to listen to the voice of the younger generation, and to address the challenge of Arab society’s norms in order to promote more egalitarian and democratic perceptions and practices.
Linguistic Diversity, Multilingualism, and Cognitive Skills: A Study of Disadvantaged Children in India

Multilingualism and linguistic diversity are the norm in India. Although studies have shown a relation between bilingualism and cognitive gains, linguistic diversity has so far been ignored as a potential factor affecting cognitive skills. This study aims to fill this gap by examining how cognitive skills—as measured by the n-back and Raven’s Colored Progressive Matrices tasks—are affected by multilingualism and/or sociolinguistic diversity in a large cohort of socioeconomically disadvantaged primary school children in two urban sites of India: Delhi and Hyderabad. We present a questionnaire estimating sociolinguistic diversity and show that this measure assesses a distinct construct, as compared to a child’s multilingualism. Children were classified as growing up monolingually or bilingually, depending on whether they grew up with one or more languages in the home. Regarding cognitive performance, bilinguals were found to outperform monolinguals on the n-back task, as well as on the Raven’s task. In addition, a socially and linguistically diverse environment seems to enhance cognitive performance for children who are not multilingual themselves. Finally, several contextual factors such as city were found to influence cognitive performance. Overall, this shows that cognitive tasks are subject to contextual effects and that bilingualism and linguistic diversity can enhance cognitive performance of children in disadvantaged contexts.
THE EVOLUTION OF SYMBIOTIC

Plants form beneficial symbioses with a variety of different microbes. Among these, the root associated arbuscular mycorrhizal fungi, ectomycorrhizal fungi, rhizobial, and actinobacterial symbioses are some of the best understood. The successful establishment of these symbioses relies on a complex, coordinated signal exchange that arose from hundreds of millions of years of coevolution between plants and their associated microbes. Despite the diversity of these microbial symbionts, common signalling mechanisms were evolved that include the manipulation of host immunity and the use of similar plantand microbe-derived signals and receptors. Owing to the plethora of information on these diverse symbioses, their signalling mechanisms are rarely reviewed together and even less so within an evolutionary context. We provide an overview of what is known regarding the evolution of these signals in an effort to highlight knowledge gaps in our understanding of plant–microbe symbiosis.
Comparison of the Incidence of Post-operative Pain and Time Taken for Instrumentation Using Manual and Rotary Techniques and Obturation in Single-Visit Endodontics, in Young Permanent Teeth-An in Vivo Study

Introduction: The present study was undertaken to compare the frequency of post-operative pain and time taken after ProTaper (NiTi) rotary and manual step-back root canal preparation techniques in single-visit endodontics. Methodology: The study was conducted in the Department of Pedodontics and Preventive dentistry, J.N kapoor D.A. V. (C) Dental College and Hospital, Yamuna Nagar, Haryana, according to the specified inclusion criteria. Exclusion criteria were strictly maintained. Patients after selection were randomly divided into two groups. In Group I: Root canals were prepared by ProTaper (NiTi) rotary instrument (Dentsply, Maillefer, Ballaigues, Switzerland). In Group II: Root canals were prepared by manual step back technique using hand files. During the procedure in both the groups, time T1 (instrumentation time), T2 (obturation time), and T3 (T1+T2) were recorded. After the procedure, the modified verbal scale (MVD) was explained to patients and instructions were given and were asked to mark the severity of pain on MVD scale at 12 h, 24 h, 48 h, 72 h, and 1 week. All patients were appointed after 1 week and evaluated for post-operative pain. Result: Less time was taken with rotary NiTi instrument as compared to manual technique, with no difference in the incidence of post-operative pain in both the groups. Conclusion: Statistically significant difference (P < 0.001) was found for the time taken for root canal therapy in both the groups, whereas no statistical difference (P = 0.586) was seen in the incidence of post-operative pain between patients treated with ProTaper (NiTi) rotary and manual step-back root canal preparation technique in single-visit endodontics.

An overview of the sexual dimorphism in

Members of the genus Echiniscus C.A. S. Schultze, 1840 are mostly unisexual, with thelytokously reproducing females. Therefore, every newly described dioecious species in the genus is particularly interesting. Here, we describe Echiniscus masculinus sp. nov. from Gunung Kinabalu, the highest peak of Borneo and the entire Southeast Asia. The new species belongs in the predominantly parthenogenetic E. virginicus complex, and its females are confusingly similar to females of the pantropical E. lineatus Pilato et al., 2008, another member of this group. However, genetic evidence and noticeable sexual dimorphism clearly delineate the new species. Males of E. masculinus sp. nov. are unlike females in the body proportions, cuticular sculpturing, and appendage configuration. The new discoveries provide a justification to review the current knowledge about evolution and forms of sexual dimorphism within Echiniscus.
Bone marrow aspirate versus two bone autograft types in reconstruction of alveolar cleft: A histomorphometric analysis

Objectives: The aim of this study was to compare histomorphometrically between bone marrow aspirate on a collagen carrier with autogenous bone grafts harvested from two different donor sites in alveolar cleft defect repair.Materials and Methods: eighteen patients with alveoalar cleft defect were included in the study. Twelve out of eighteen patients were reconstructed with auotogenous bone graft; six patients grafted with illium bone graft and six patients grafted with chin bone graft. The remaining patients out of eighteen were reconstructed using bone marrow aspirate implanted on a collagen carrier. Six months after grafting, bone specimens from augmented alveolar ridge sites were retrieved by trephine burs for histomorphometric analysis. Results: Good consolidation of the grafts have been observed, this was demonstrated by intense osteogenesis indicating an active remodeling process. In all groups, the improvement in bone quality of the receptor site was clear with no statistical significance between the groups, however, the autografts presented better bone quality.Conclusions: From this study it was possible to conclude that quality of bone repair using autogenous bone graft is superior to bone marrow aspirate. The time needed for bone maturation is less when chin or iliac autogenous grafts have been used in comparison to the bone marrow aspirate.
The intertwined features of trap charges and surface mobility in the MOS and MOSFET Devices fabricated on elemental Silicon and compound semiconductors such as Silicon Carbide and Gallium Nitride

4H-SiC and GaN (0001) oriented surfaces compare to the Si (111) surface in terms of planar density of atoms, therefore the charge densities in MOS devices fabricated on these surfaces can be compared. The positive charge and deep “Border” trap densities in the MOS devices on 4H-SiC (0001) surface and the Si(111) surfaces correlate to each other with the charge and trap density in the 4H-SiC MOS devices being three times those in the Si MOS devices at 12 x 10 11 /cm 2 in the wet oxidised/wet re-oxidised/Ar annealed sample. The Nf values in the p-type and n-type devices on Si-face of 4H-SiC create a window of 36 x 10 11 /cm 2 as the charge density. Moving the window to the left through processing increases the leakage current and lowers the oxide breakdown field. Moving the window to the right increases the density of near interface traps (NITs) that reduces the surface mobility of the n-channel MOSFET. A high value of interface trap density implies a higher density of carbon atoms at the SiC/SiO2 interface. The window of ∆Nf could be related to the density of PbC centres on 4H-SiC which is found to be 30-40 x 10 11 /cm 2 . One-third of the window represents density of E’ centres near the SiO2/Si(111) interface at 12 x 10 11 /cm 2 because of absence of carbon and indicates better interface abruptness. The surface mobility in MOSFETs formed on SiC and GaN are dominated by Coulomb scattering when the mobility is shown to be inversely proportional to the total interface and near interface trap densities at room temperature. This relation gives a surface field effect mobility of electrons on n-channel 4HSiC MOSFETs to be about 45 cm 2 /V-s with the oxide having a high breakdown field of 7.8 MV/cm with charges. This mobility is observed experimentally on 4H-SiC MOSFETs having NO annealed oxides. A higher mobility on n-channel MOSFETs fabricated on (1120) surface has a lower oxide breakdown of about 5MV/cm due to the presence of high density of positive fixed charges in the p-type MOS devices. The MOSFETs on GaN surface is expected to have a similar behaviour as on 4H-SiC giving low mobility of about 45 cm 2 /V-s as the trap densities are of the same order of low 10 12 /cm 2 eV.
Prediction Using Markov for Determining Location of Human Mobility

Human mobility in urban area related to how people moved from a city to another city, whether by walking or using vehicles to support their mobility. By processing data of human mobility, we can determine prediction of the next pattern of human mobility. Some methods for human mobility prediction have been proposed. One of them is predication using Markov. In this research, we conducted implementation of Markov algorithm to predict location of human mobility based on input data form individual mobility dataset (GeoLife) from GPS. This research carried out through five stages of research and conducted between December 2017 until June 2018. The conclusions drawn from this study are the values for parameters such as HMM n_components = 5, covariance_type = 'spherical', and decoder algorithm = 'viterbi' which produces a curation of 0.769 and RMSE 1,641 can be said to be hmm good enough in modeling data.
Temporal Clustering and Anomaly Detection in Elderly-friendly Smart Cities

—In this paper, we propose a methodology for behavior variation and anomaly detection from acquired sensory data, based on temporal clustering models. Data are collected from smart cities that aim to become fully “elderly-friendly”, with the development and deployment of ubiquitous systems for assessment and prediction of early risks of elderly Mild Cognitive Impairments (MCI) and frailty. Our results show that Hidden Markov Models (HMMs) allow efficient (1) recognition of significant behavioral variation patterns and (2) early identification of pattern changes.
A MATHEMATICAL EXPLORATION OF PHYTOPLANKTON BLOOMS IN THE NORTH ATLANTIC by

Phytoplankton are the base of the marine food web. They are also responsible for much of the oxygen we breathe and they remove carbon dioxide from the atmosphere. The cause of seasonal phytoplankton blooms in the ocean is a debated topic. One hypothesis is that blooms are initiated when seasonally changing environmental conditions disrupt the balance in the predator-prey relationship between zooplankton and phytoplankton. This dissertation follows up on this notion with a Nutrient-Phytoplankton-Zooplankton (NPZ) model incorporating diffusion and depthdependent coefficients. Full spatiotemporal solutions of this coupled reaction-diffusion system are computed. An explanation of the bloom process in this model is presented that involves a saddle point transient equilibrium state. The saddle point bloom process is demonstrated with an ordinary differential equations NPZ model with time dependent forcing to imitate seasonally oscillating solar radiation. This process is illustrated by an animation (movie1 ODE.avi). The details from this analysis inform the bloom process in the reaction-diffusion NPZ model for which the equilibria must be determined computationally. The bloom process in the reaction-diffusion NPZ model is illustrated by another animation (movie2 PDE.avi). The reaction-diffusion NPZ model, incorporated with seasonal solar radiation and mixed layer depth data, simulates blooms with better timing than the ordinary differential equations model but still leaves much to be desired. However, results from models that simulate blooms more accurately show signs of the saddle point bloom process described in this dissertation. The saddle point bloom mechanism described here could be the mechanism by which the seasonal disruption in ecological balance initiates a high-latitude marine phytoplankton bloom, like that in the North Atlantic Ocean.
EFFECTS OF A 6-WEEK CONTROLED EXERCISE PROGRAM AND SEMI-CONTROLED DIET ON BODY FAT AND SKELETAL MUSCLE MASS IN ADULTS

2019. Т. 19, No 1. С. 7–14 7 INTRODUCTION Human body composition consists of nearly 40 components divided in 5 levels, and all those components contact and interact between each other and play certain roles in the body [25]. Therefore, certain body composition components are often considered to be sensitive indicators of health and physical fitness [2, 10, 11, 16], wherein body fat mass (FM) is the biggest ballast tissue in contrast to skeletal muscle mass (SMM) which represent the main movement potential. In an extensive review on anti-inflammatory effects of exercise, the association between the increased fatness (especially in the abdomen) and all-cause mortality, dementia, and several cancers were explained by an increase in the production of pro-inflammatory adipokines and reduced production of anti-inflammatory cytokines [11]. Furthermore, Garibalda et al. [10] observed significantly higher blood pressure, c-reactive protein levels, pro-inflammatory cytokine levels, and protein carbonyls contents and lower β-carotene levels among women in the fourth quartile than in the first quartile for body mass (BMI) and waist circumference WC (p < 0.01). On the other side, SMM is shown to be sports-specific in athletes [2, 9], and the significant predicting variable of general physical fitness in police officers [26]. Moreover, Dopsaj et al. showed that young waterpolo players were 5.01 kg heavier than the control group, most probably due to higher SMM, but also were exerting significantly higher hand grip forces. In contrast, ageing was found to be associated with a reduction in SMM which potentially may lead to disability and impairment in people with low amounts of SMM [13, 14]. However, various strategies of body compositon management have been investigated, and Физиология
PROTECTIVE EFFECT OF SOME FERMENTED DAIRY PRODUCTS ENRICHED WITH DIBS ON TOTAL POLAR COMPOUNDS FORMED DURING DEEP – FAT – FRYING PART I: ON BIOLOGICAL EXAMINATION OF RATS

During deep fat frying , oils is exposed to elevated temperatures above 180C during intermittent frying for 40 hrs at 5 consecutive days. Toxicity of used oil for deep frying was related to its content of total polar compounds (TPC), caused abnormal changes in weaned rats. Ultimately, nutrition quality of the oil can be affected. The chemical assessment of date flesh, dibs, yoghurt, yoghurt and biogarde enriched with 5% dibs showed significantly (P<0.05) differences in all previous samples. Dibs samples recorded the highest amount of total sugars, reducing sugars, dietary fibers, total phenolics and minerals . It was interest to notice that using of dibs in the manufacture of yoghurt and biogarde ( enriched with 5% ) on the experimental rats groups . The objective of this study, were to investigate the influences of date palm syrup, plain yoghurt, yoghurt and biogarde enriched with 5% dibs on total polar compounds formed during deep frying of cotton seed oil on biological evaluation of experimental rats. The control group fed on non fried oil, the second rats control had fed fried oil containing over 25% TPC for 28 days. The second rats control group were divided into four groups (n=10), and were fed for 28 days on date syrup (dibs), plain yoghurt, yoghurt and biogarde fortified with 5% dibs. Oral administration of TPC caused hepatotoxicity as monitored by increase in both of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) enzymes, Compared with first control rats group, and fermented dairy products groups. Also, caused abnormal changes in kidney functionality compared with first control rats group. Particularly, total lipids, triglycerides, phospholipids, cholesterol and LDL cholesterol were found increased by TPC, while glucose was reduced significantly compared with the fermented dairy products supplemented with 5% dibs groups. Therefore, it could be recommended that the nutritional products enriched with dibs provides several therapeutic benefits including reduction of cholesterol, LDL cholesterol and protective effect of liver and kidney cells.
L’activation du PDGFR favorise le phénotype agressif des synoviocytes de patients atteints de polyarthrite rhumatoïde via la formation d’invadosomes

Fibroblast-like synoviocytes (FLS) play a major role in invasive joint destruction in rheumatoid arthritis (RA). This pro-destructive phenotype has been shown to involve autocrine TGF that triggers formation of matrix-degrading invadosomes through molecular mechanisms that are not fully elucidated. The PDGFR family of receptor tyrosine kinases (RTK) has been shown to cooperate with TGFin various pathological conditions. We therefore sought to determine whether RTK activity played a role in invadosome biogenesis. We demonstrated that, among the common RTKs, PDGFR- was specifically phosphorylated in FLS from RA patients. Phosphorylation of PDGFR- was also elevated in RA synovial tissues. Interference with PDGFR activation or PDGF neutralization inhibited invadosome formation in RA synoviocytes, indicating the presence of an autocrine PDGFR activation loop that involved endogenous PDGF. Among the PDGFA-D isoforms, only PDGF-B was found both significantly elevated in FLS lines from RA patients, and related to high-invadosome forming cells. Addition of TGFupregulated invadosome formation, PDGF-B mRNA expression, and phosphorylation of PDGFR. All these functions were efficiently suppressed by TGFneutralization or interference with the Smad/TR1 or PI3K/Akt pathway. Among the class 1 PI3K family proteins known to by expressed in RA synoviocytes, PI3Kα was selectively involved in PDGF-B expression while both PI3Kα and PI3Kδ participated in invadosome formation. Our findings demonstrate that PDGFR is a critical RTK required for the pro-destructive phenotype of RA synovial cells. They also provide evidence for an association between autocrine TGFand PDGFR-mediated invadosome formation in RA synoviocytes that involves the production of PDGF-B induced by TGF.
Clinical and Radiographic Assessment of Pulpotomy Materials in Primary Molars

Aim or purpose: Clinical and radiographic evaluation of four different materials utilized in vital pulpotomy in mandibular primary molarsMaterials and methods: one hundred and sixty mandibular primary molars in forty children were included as split mouth design. Patients were medically free with an age range from 4-6 years. Inclusion criteria: patients presented with deep carious lesions including the first and second primary molars bilaterally, no evidence of any clinical pathology, mobility and had no tenderness to percussion. Pre-operative radiographs showed no evidence of external or internal root resorption, absence of furcal, periapical radiolucency or widened periodontal ligament space and no more than one-third root resorption detected. The included molars undergone vital pulp therapy and bilaterally randomly divided into four equal groups, group (1) formocresol, group (2) ferric sulphate, group (3) MTA (mineral trioxide aggregate) and group (4) Metapex (calcium hydroxide &iodoform). All treated molars were evaluated both clinically and radiographically for 12 months evaluation period. Data were collected and analysed statistically.Results: It was shown that, at base line, there was no statistically significant difference between clinical as well as radiographic success rates among the four groups. After 3 as well as 6 months, there was a statistically significant difference between clinical and radiographic success rates among the four groups. FS, MTA and Metapex groups showed higher clinical and radiographic success rates than FC group.Conclusions: Ferric sulphate, mineral trioxide aggregate (MTA) and Calcium hydroxide and iodoform paste (Metapex) provide clinically acceptable alternative to formocresol in vital pulp therapy in primary teeth.
Average vs. local structure and composition-property phase diagram of K0.5Na0.5NbO3-Bi1⁄2Na1⁄2TiO3 system

Phase diagram of the solid solution system K0.5Na0. 5NbO3Bi1⁄2Na1⁄2TiO3 [(1-x)KNN-xBNT] has been established from dielectric permittivity measurement and structure analyses. The unit cell volumes continuously decrease depending on the composition, while the local structure maintains distortions away from the cubic average structure in the range 0.10 ≤ x ≤ 0.90. No clear correspondence for the temperatures of phase transition exists between structural studies and physical properties. The dielec-
