Some aspects of using mixed reality technologies in the training of physics teachers

The introduction of modern technologies in the learning process at school is an important task, both for the education system as a whole and for an individual teacher. The ability to work with new teaching aids allows the teacher to interest students in their subject. One of these tools is virtual and mixed reality headsets. The emphasis is on mixed reality, although the two are often closely related. The article provides a brief overview of works devoted to the use of mixed reality in teaching physics, a study of the readiness of students of a pedagogical university to use this technology in their future professional activities is carried out. The questionnaire for expert assessment of mixed reality developments has been modified, and a survey of experts in this field has been conducted. The results of the research may be of interest to teachers of various specialties, senior students and graduate students in the field of physics teaching methods.
Structural Performance of Innovative Precast Hollow Concrete Walls for Buildings

Depleting fossil fuels and the stringent conditions being imposed by the global community to reduce greenhouse gas emission, construction industry will be pushed to innovate energy efficient building systems. The conventional concrete building units are energy intensive firstly in terms of raw material manufacturing secondly during operation. Further, these buildings require extensive site preparation and construction time. Several ways have been proposed to tackle the problem of energy efficiency of buildings and each of those has shortcomings. The climate of Saudi Arabia is characterized by hot and arid because of which residential energy consumption for cooling is very high. A new hollow precast structural wall system is proposed which has multiple benefits including, energy efficiency and economy. In this paper, the structural evaluation of a two-storied residential building using the new wall system is presented. The building with hollow precast wall panel as structural load bearing walls, subjected to gravity, wind and seismic loading was investigated using finite element modelling. In-situ thermal performance of the constructed housing unit was investigated in addition to the full-scale load testing. From the results of structural evaluation, it can be concluded that the proposed energy efficient wall units offer a robust construction system for buildings and provides strong resistance to lateral and gravity loadings. Additionally, these wall units coupled with the hollow core slabs provide a fast track construction technique.
Advancement of motion psychophysics : Review 2001

This is a survey of psychophysical studies of motion perception carried out mainly in the last 10 years. It covers a wide range of topics, including the detection and interactions of local motion signals, motion integration across various dimensions for vector computation and global motion perception, second-order motion and feature tracking, motion aftereffects, motioninduced mislocalizations, timing of motion processing, cross-attribute interactions for object motion, motion-induced blindness, and biological motion. While traditional motion research has benefited from the notion of the independent “motion processing module,” recent research efforts have been also directed to aspects of motion processing in which interactions with other visual attributes play critical roles. This review tries to highlight the richness and diversity of this large research field and to clarify what has been done and what questions have been left unanswered.
Alesiella gen.n. and a newly discovered relict lineage of Staphylinini (Coleoptera: Staphylinidae)

This study aimed to identify the sister group of the poorly known and morphologically isolated Burmese species Quedius lineipennis within the tribe Staphylinini (Staphylinidae: Staphylininae) using morphological characters. Phylogenetic analysis of a broad taxon sample demonstrated that this Asian species is not a member of the genus Quedius but forms the sister taxon to the Neotropical genus Quediomacrus. Both taxa were shown to be members of a hitherto unrecognized lineage with a highly disjunct distribution. The lineage is hypothesized to be Asian in origin, with dispersals to the Americas during the early Eocene climatic maximum via Beringia and to Australia via land connections in the late Miocene. The current distribution of the lineage is considered to be relictual. New phylogenetic hypotheses within ‘Quediina’ and Staphylinini as a whole are proposed and the general tree topology of Staphylinini recovered by recent morphological studies is refined. Phylogenetic relationships within the Quedius complex remain unclear. Alesiella Brunke and Solodovnikov gen.n. , is erected for Quedius lineipennis and the Quedius subgenus Quedionuchus is reinstated to genus level with new combinations as follows: Quedionuchus atl (Smetana, 1975), comb.n. ; Quedionuchus calli (Smetana, 1976), comb.n. ; Quedionuchus cipactli (Smetana, 1976), comb.n. ; Quedionuchus coatl (Smetana, 1976), comb.n. ; Quedionuchus ehacatl (Smetana, 1976), comb.n. ; Quedionuchus ollin (Smetana, 1976), comb.n. ; Quedionuchus ozomatli (Smetana, 1975), comb.n. ; Quedionuchus reitterianus (Bernhauer, 1944), comb.n. ; Quedionuchus samuraicus (Bernhauer and Schubert, 1916), comb.n. ; Quedionuchus schultzei (Smetana, 1975), comb.n. ; Quedionuchus tecpatl (Smetana, 1976), comb.n. ; Quedionuchus xochitl (Smetana, 1976). Quedius lugubris Lokay, 1913 is transferred from the subgenus Quedionuchus to the subgenus Distichalius and placed in synonymy: Quedius punctatellus (Heer, 1839) = Quedius lugubris Lokay, 1913, syn.n.
How Increased School Choice Affects Public School Enrollment and School Segregation

We investigate the determinants and consequences of increased school choice by analyzing a 22-year school panel matched to county-level demographic, economic, and political data. Using an event-study design exploiting the precise timing of charter school enrollment change, we provide robust evidence that charter enrollment growth increases racial and especially socioeconomic school segregation, a finding that is partially explained by non-poor students’ transition from the private to public sector. Charter growth drives public sector incorporation, while also increasing within-public sector segregation. To assess the effects of disparate choice policies on segregation, we replicate this analysis for magnet schools, which have admissions practices intended to increase diversity, and find no evidence that magnet enrollment growth increases segregation.
Controversies in regenerative medicine: Should intervertebral disc degeneration be treated with mesenchymal stem cells?

Low back pain (LBP) can significantly reduce the quality of life of patients, and has a considerable economic and social impact worldwide. It is commonly associated with disc degeneration, even though many people with degenerate discs are asymptomatic. Degenerate disc disease (DDD), is thus a common term for intervertebral disc (IVD) degeneration associated with LBP. Degeneration is thought to lead to LBP because of nerve ingrowth into the degenerate disc, inflammation, or because degradation of extracellular matrix (ECM) alters spinal biomechanics inappropriately. Thus, while the objectives of some interventions for LBP are to control pain intensity, other interventions aim to deal with the consequences of disc degeneration through stabilizing the disc surgically, by inserting artificial discs or by repairing the disc biologically and preventing progressive IVD degeneration. Despite tremendous research efforts, treatment of LBP through the use of regenerative interventions aiming to repair the IVD is still controversial. The use of mesenchymal stem cells for IVD regeneration in a patient‐based case will be discussed by an ensemble of clinicians and researchers.
Genetic Algorithm for lecturing schedule optimization

Scheduling is a classic problem in lecturing. Rooms, lecturers, times and scheduling constraints must be managed well to get an optimal schedule. University of Boyolali (UBY) also encounter the same scheduling problems. The problem was tried to be solved by building a library based on Genetic Algorithm (GA). GA is a computation method which inspired by natural selection. The computation consists of some operators i.e. Tournament Selection, Uniform Crossover, Weak Parent Replacement and two mutation operators (Interchanging Mutation and Violated Directed Mutation (VDM)). The two mutation method are compared to find which better mutation operator. The library was planned to have a capability to define custom constraints (scheduling requirements that were not accommodated by the library) without core program modifications. The test results show that VDM is more promising for optimal solutions than Interchanging Mutation. In UBY cases, optimal solution (fitness value=1) is reached in 12 minutes 41 second with adding 6 new room and inactivated 2 constraint i.e. lecturing begins at 14.00 except for 3rd semester of science law study program with morning class and lecturing participants must not over classroom capacity.
Application of sevoflurane inhalation combined with epidural anesthesia in patients with colorectal cancer and its effect on postoperative perceptual function

Effect of sevoflurane inhalation combined with epidural anesthesia on postoperative perceptual function in patients with colorectal cancer (CRC) was investigated. The clinical data of 78 patients undergoing laparoscopic CRC radical surgery in The Second Cancer Hospital of Heilongjiang Province from June 2016 to June 2017 were retrospectively analyzed and divided into 2 groups: Sevoflurane inhalation combined with epidural anesthesia (observation group, n=40); propofol intravenous general anesthesia (control group, n=38). The mean arterial pressure and heart rate before anesthesia (T0), immediate intubation (T1), 30 min after surgery started (T2), end of surgery (T3), 10 min after extubation (T4) were compared between the two groups. The recovery conditions were also compared between the two groups. The cognitive functions were evaluated by mini-mental state scale (MMSE). The mean arterial pressure and heart rate in the observation group were significantly lower than those in the control group at T2, T3 and T4 (P<0.05). The recovery time, extubation time, anal exhaust time, eating time, urinary catheter removal time and hospital stay in the observation group were significantly lower than those in the control group (P<0.05). There was a significant difference in cognitive function between the two groups at different time points (P<0.001). Postoperative cognitive function showed a trend of decreasing first and then increasing; the scores of cognitive function in both groups 1 day after surgery were at trough level, and recovered gradually from 3 days after surgery. The mean arterial pressure and heart rate during the perioperative period are more stable in the elderly patients with sevoflurane inhalation combined with epidural anesthesia; the recovery time is shorter and more rapid, and the recovery time of postoperative cognitive function is also faster. Therefore, it provides a reference for patients undergoing CRC radical surgery to select high-quality and appropriate anesthetic protocols.
A REVIEW ON OPTIMIZING FORAGE QUALITY THROUGH MANAGEMENT

Forage crops are important for the national economy since they form the nutritional base for our livestock population. A recent estimate indicates that there is a gap between total forage need and its availability by about 68% of green fodder and about 53% of dry forage. Due to ever increasing population pressure of human, arable land is mainly used for food and cash crops, thus there is little chance of having good quality arable land available for fodder production, until milk production is remunerative to the farmer as compared to other crops. Feed and fodder cost constitute about 60-65 percent of the total cost of milk production which can be reduced to 30-40 per cent by providing cheap and quality of roughages such as natural and cultivated grasses. The nutritive value of a forage or feed measures of proximate composition, digestibility and nature of digested products and their by ability to maintain or proximate growth, milk production, pregnancy or other physiological function in the animal body. Animal, itself is the best judge for forage quality evaluation, which can be determined through palatability, growth rate and milk production.
The Implementation of Picture Exchange Communication System: A Mother’s Perspective of a Young Child with Pervasive Developmental Disorder

Picture Exchange Communication System (PECS) is a functional means of communication intervention designed for individuals with a variety of communicative challenges. The purpose of this study was to interview a mother who implemented PECS for her 3;03 year old child with Pervasive Developmental Disorder. The interview aimed to investigate a mother’s perception about the efficacy of PECS and issues related to PECS intervention. The results of the interview showed that PECS was effective in enhancing communication skills and reducing problematic behaviours. PECS also had a slight impact on speech production of the child. The issues related to PECS intervention were discussed.
The Exploration Of Argument Scheme Expression In Students‘ Proof Construction

This study aimed to know the malformation of argument scheme in proof construction. There were two classes as subject of the research to do the quizes given by the researcher about proofing the theory construction then the proff construction was being schemed based on Toulmin Argument Scheme. Argument scheme which had malformation could be proved in 0,1,2,3, and 4. Malformation 0 signed by no argument at all in producing the argumet scheme. Malformation 1 signed by some pronouncement with no argument scheme. Malformation 2 signed by some pronouncements with incomplete argument scheme. Malformation 3 signed by one argument scheme with no conclusion. Malformation 4 signed by the produced of full incomplete argument scheme.
The Impact of Intergenerational Transfers on Household Wealth Disparities in Japan and the United States

To help shed light on the implications of intergenerational transfers for wealth inequality, this paper examines whether or not individuals who receive intergenerational transfers from their parents are more likely to leave bequests to their children than those who do not using data on Japan and the United States. The estimation results show that the receipt of intergenerational transfers from parents and/or parents-in-law increases the likelihood of individuals’ leaving bequests to their own children in both Japan and the United States, which might contribute to the persistence or widening of wealth inequalities. However, such a tendency is found to be stronger among less better-off households in both countries, and this may help alleviate the disequalizing effect of intergenerational transfers on wealth distribution, at least to some extent.

Regional attractiveness for Foreign Direct Investments in developing countries: empirical review

Foreign direct investments are very important for the economic growth and development of the host countries; however these investments have a tendency to concentrate in few developed regions within the recipient countries, thus contributing to the widening of regional disparities. The economic and social impact of FDI on host countries is considerable that’s why many scholars have studied the location determining factors of those investments. This paper offers a review of the empirical literature that deals with the economic determining factors of FDI location choice at the regional level in developing countries. We analyze the role of the most commonly cited factors in the literature, these are the following: the agglomeration economies, the market size, the infrastructure, and the human capital. We focus on the case of the regions of the following countries: China, Brazil, Turkey, Romania and Morocco. We conclude that the influence of each factor or (explanatory variable) in attracting FDI differs from one region to another. Indeed, depending on their geographic location and economic structures, regions attract differently FDI. This suggests that the gap between rich and poor regions will widen in the long term.
Reducing Contact Resistance in Two-Dimensional-Material-Based Electrical Contacts by Roughness Engineering

The engineering of efficient electrical contacts to two-dimensional (2D) layered materials represents one of the major challenges in the development of industrial-grade 2D-material-based electronics and optoelectronics. In this paper, we present a computational study of the contact resistance and current-flow distribution for electrical contacts between 2D materials and three-dimensional (3D) metals and between different 2D materials. We develop models of the electrical contact resistance for 2D/2D and 2D/3D metal/semiconductor contact interfaces based on a self-consistent transmission-line model coupled with a thermionic charge-injection model for 2D materials and first-principles simulation by density-functional theory, which explicitly includes the variation of the electrostatic potential in the contact region. We compare the results of our self-consistent calculations with existing experimental work and obtain excellent agreement. It is found that the presence of contact interface roughness, in the form of fluctuating Schottky barrier heights in the contact region, can significantly reduce the contact resistance of ${\mathrm{Mo}\mathrm{S}}_{2}$/metal Schottky 2D/3D contacts. Our findings suggest that roughness engineering may offer a possible paradigm for reducing the contact resistance of 2D-material-based electrical contacts.
Development Of Mulberry Enriched Fruit Jam By Replacing Refined Sugar With Mulberry Fruit

Excessive consumption of refined sugar is leading Indian population to obesity, which leads to the development of non-communicable diseases. The present study was designed to develop mulberry leaf powder enriched fruit jam by replacing refined sugar with mulberry fruit. Mulberry fruit, mulberry leaf powder, apple, pomegranate, orange and other ingredients were used to prepare six variants of enriched fruit jam and control sample (without mulberry leaf powder). Enriched fruit jam was prepared by keeping the amount of mulberry fruit as 40% (constant) and varying amount of other ingredients such as mulberry leaf powder as T1 (3%), T2 (6%), T3 (9%), T4 (12%) and T5 (15%) respectively. The mulberry enriched fruit jams were evaluated for nutritional quality and sensory attributes. Data obtained were then analyzed statistically using ANOVA at 5% level of significance by SPSS software version 0.25. It was found that a treatment combination T5 (15%) of mulberry leaf powder had the highest content of energy, protein, fat, total carbohydrate and dietary, while a treatment T1 (3%) of mulberry leaf powder was best in term of color, texture, flavor & taste and overall acceptability as compared to control T0. The mulberry enriched fruit jam gained acceptability in terms of sensory attributes, hence was concluded to be a nutritious product for children, adolescent, adult as well as overweight without compromising the nutritional profile.
Seasonal response of ponderosa pine to inoculation of the mycangial fungi from the western pine beetle

The hypersensitive response obtained by inoculating the two mycangial fungi of the western pine beetle, Dendroctonus brevicomis LeC, and the blue-stain fungus, Ceratocystis minor Hedge, into ponderosa pine was measured during three different seasons in the same 12-month period. The lesions were produced faster and were significantly longer in the fall than in the summer. Similarly, lesions were longer and were produced faster when inoculations made in the summer were compared with spring inoculations. However, the response to a nonpathogenic fungus, a Penicillium sp. , was not different from the response to mycangial fungi, suggesting that lesion production is a generalized response to infection that isolates fungus-colonized tissue from the rest of the tree. Ethanol extracts of hypersensitive-response lesions produced during the spring did not reduce growth of the mycangial fungi or C. minor when bioassayed at concentrations similar to those found in host tissue. This is different from other bark beetle–h.
Field catches of Oxythyrea cinctella using visual and olfactory cues

Diurnal flower‐visiting scarabs (Coleoptera: Scarabaeidae, Cetoniinae) use visual and olfactory stimuli when locating possible feeding sites. In field trapping experiments in Turkey, testing different colours and floral volatile compounds, a combination of fluorescent yellow colour and a blend of 2‐phenylethanol and (±)‐lavandulol leads to the highest number of Oxythyrea cinctella (Schaum) being caught. Trap catches of O. cinctella with respect to the individually presented visual or olfactory cues are significantly lower than to a combination of the two. The closely‐related O. funesta, a sibling species in the Oxythyrea genus, is also known to be caught by the same colour‐volatile combination. When applied together in a high capture‐capacity trap, the fluorescent yellow colour and the binary floral odour blend may provide a suitable means of monitoring population changes of O. cinctella, which indicates their potential use in agriculture.
Morfoanatomía y respuesta fisiológica de las semillas de chambimbe a condiciones de crioconservación

En los laboratorios de la Universidad Nacional de Colombia Sede Palmira y del Instituto Humboldt del Centro Internacional de Agricultura Tropical (CIAT) se realizo el estudio de caracterizacion, descripcion morfoanatomica y evaluacion de tratamientos de escarificacion mecanica de semillas de chambimbe cosechadas en agosto de 2005 en Palmira. La estructura de proteccion la constituye un tejido conformado por varias capas, la mas externa lignificada y de color negro, que tambien regula el intercambio liquido y gaseoso a traves del micropilo; muchas veces el poro esta sellado. El contenido de humedad de semillas cosechadas del suelo fue de 12% y el mejor tratamiento de escarificacion fue la perforacion cerca del micropilo con taladro manual (96% de germinacion). El secado (silica gel) y la crioconservacion (nitrogeno liquido) durante un mes afectaron la germinacion, indicando el posible comportamiento no ortodoxo de estas semillas, las cuales se pueden almacenar con 12% de humedad y 92% de germinacion.
