Mathematics learning instrument using augmented reality for learning 3D geometry

Augmented Reality (AR) is one kind of Virtual Reality (VR) technologies that can be used to help students who have difficulties to imagine geometrical objects in three-dimension way. AR can be applied in mobile learning which will improve the efficiency and effectiveness in learning process. The aim of this study was to develop the mathematics learning instruments using AR for secondary students. The methodology that used in this study was research and development. Sketchup software is used to draw geometrical objects and AR application can be used to view the objects in 3D. The subjects of this study were 15 students of grade nine. Experts’ assessments and students’ responses results were used to collect the data. The finding shows that the instrument is categorized as valid and it can be implemented in learning process. The validity aspects consist of languages, contents, and design. Besides, the instrument can be used in learning process, catch students’ interest and help them to understand geometry contents.
EFFECT OF SELECTED FACTORS ON MASS CONCENTRATION OF AIRBORNE DUST DURING WOOD SANDING

Sanding with handheld powered tools has been recognized as one of the most significant factor in personal exposure to wood dust in the woodworking industry. The aim of this study was to investigate the effects of wood species and grain size of abrasive on wood removal and mass concentration of wood dust emitted by a random orbit sander. Experimental study was designed as 4x4 full factorial experiments. The mass concentration of emitted wood dust was measured using aerosol monitor DustTrak DRX 8533. The results of this study confirm that softwood species generated higher dust concentrations than hardwood species due to difference in abrasion durability. Compared to sanding disc with P40 grit size, approximately 48% higher dust concentration was generated when the sanding disc with P240 grit size was used.
Estimating The Incidence Of Japanese Encephalitis In Divisions Of Bangladesh

Japanese Encephalitis (JE) is a mosquito-borne viral disease responsible for 30,000 to 50,000 reported cases and up to 15,000 reported deaths every year. The disease is a significant public health concern in Bangladesh, but there is no regular surveillance or immunization for JE in the country. The objective of this study is to determine whether a practical model to estimate the incidence of JE in Bangladesh can be developed using data on population, environmental characteristics, and/or vector distribution for JE-endemic countries in Asia and the Western Pacific. Information on JE incidence, area, land cover, climate, population characteristics, land elevation, and distribution of mosquito vectors was collected for JE-endemic areas. Sources of the information included population and agricultural censuses, the Food and Agricultural Organization of the United Nations, the WHO, WorldClim, the CIA World Factbook, and mosquitomap.org. Generalized linear models examined the association between the variables and the outcome of Japanese Encephalitis. The best model was used to estimate the incidence of JE in each division of Bangladesh. The most statistically significant model used a negative binomial distribution and included variables for population density (p=.0052), mean annual temperature (p<.0001), annual range of temperatures (p<.0001), and mean temperature of the warmest quarter (p<.0001), with the population size as an offset variable. The estimated incidence in each division of Bangladesh ranged from 2.6 to 5.9 cases per 100,000 population. The division with the highest risk for JE was Rajshahi. A pilot vaccination program in that division may be more cost-effective than in other divisions. Limitations in data quality may have hindered the utility of several variables, so active case-finding may be useful for validating the model.

Effect of Calcination Temperature on Photocatalytic Activity of Synthesized TiO2 Nanoparticles via Wet Ball Milling Sol-Gel Method

In this work, TiO2 nanoparticles were successfully synthesized with narrow size distribution via a wet ball milling sol-gel method. The effect of calcination temperature on photocatalytic activity was observed from particle size, crystallite size, and phase transition of TiO2 nanoparticles. Increasing calcination temperature increased particle size, crystallite size, and the crystallinity of synthesized TiO2. Phase transition depended on variation in calcination temperatures. A two-phase mixture of anatase and brookite was obtained with lower calcination temperature whereas a three-phase mixture appeared when calcination temperature was 500–600 °C. With higher temperature, the rutile phase kept increasing until it was the only phase observed at 800 °C. Anatase strongly affected the photocatalytic activity from 300 °C to 600 °C while the particle size of TiO2 was found to have a dominant effect on the photocatalytic activity between 600 °C and 700 °C. A mixture of three phases of TiO2-600 exhibited the highest methylene blue degradation with the rate constant of 9.46 × 10−2 h−1 under ultraviolet (UV) irradiation.
Effects of quercetin on ionizing radiation-induced cellular responses in HepG2 cells

Background: Querce n has been reported to modulate cell prolifera on and apoptosis. The present study aimed at iden fying whether treatment of ionizing radia on (IR) combined with querce n induces apoptosis in HepG2 cells. Materials and Methods: HepG2 cells were plated at an appropriate density according to each experimental scale and irradiated with 1, 5 and 10 Gy gamma-rays from a 60 Co source at room temperature. Cell viability, SOD and CAT were assessed by using commercial assay kits. Western blot analyses were done on apoptosis related proteins. The cells were treated with various concentra ons of querce n alone or in combina on with IR. Results: The cell viability was decreased in a concentra on-dependent manner 24 h a3er treatment of querce n. It was significantly lowered a3er the combined treatment of querce n with IR than that of the cells treated with querce n alone. Moreover, querce n increased the expression of p53 levels in a dosedependent manner. Combined treatment of querce n with IR significantly increased the levels of pro-apopto c proteins, cleaved caspase-3 and caspase -7, and Bax. Cell cycle analyses indicated a dras c increase in the Sub G1 popula on a3er querce n treatment combined with IR. The ac vity of caspase-3 increased coincidently with apoptosis. The combined treatment of querce n with IR decreased catalase and superoxide dismutase ac vi es, as well. Conclusion: Querce n made the radio-resistant HepG2 cells undergo apoptosis by ac va ng p53. These results suggest that the combined treatment of querce n with IR may provide an effec ve therapeu c strategy to improve the radiotherapy efficacy.

Hormonal Profile, Antioxidant Status and Some Biochemical Parameters during Pregnancy and Periparturient Period in Dromedary She Camel

THIS STUDY aimed to determine the changes in the hormonal and biochemical profile of pregnant dromedary camels to provide a baseline data under Egyptian climatic conditions. Blood samples were collected from15 pregnant she-camels aged 5-11 years old just postconception and thereafter monthly during gestation period and during periparturient period (at days 15, 7,4and 1prepartum,at parturition and at days 1, 4, 7 and 15 postpartum). Progesterone level increased significantly (P<0.05) after conception and during the1stand the 2ndtrimester of pregnancy then declined significantly (P<0.05) during the 3rd trimester. Meanwhile its level decreased significantly (P<0.05) during periparturient period. Cortisol level significantly (P<0.05) increased at the 3rd trimester and continued increasing significantly during prepartum period with a maximum level on the day of parturition after that it was markedly decreased during the few days postpartum to day 15 postpartum. Thyroid hormones levels were significant (P<0.05) decreased in their levels from early to late gestation then increased significantly (P<0.05) from day of parturition to day 15 postpartum. Total protein and albumin were significantly low (P<0.05) in the 2nd and the 3rd trimesters than the first one with no significance alterations in globulin levels. Total antioxidant, glutathione and ascorbic acid levels were lower in the 3rd trimester than others, whereas the levels were relatively low in prepartum than 15 days postpartum. Malondialdehyde concentration was significantly increased (P<0.05) during late pregnancy period as a result of the physiological stress of pregnancy
Reconstructing The Past: The Measurement Of Aggregate Product

This paper summarizes the author’s considerations on the measurement of a national economy’s historical aggregate product. Given the sources from which we can start, and the objective we wish to reach, the proper path follows logically; the extant corpus of historical national accounts seems to follow a very different path, uninformed by due reflection.

The Revival of Agriculture and Inclusive Growth during the Commodity Boom in Latin America

Latin America has constituted a recent example of inclusive growth by reducing poverty and income inequality simultaneously during the latest commodity boom. Against the backdrop of non-inclusive and non-transformative nature of commodity booms, we ask whether growth of agriculture was able to speed up structural transformation, and, relatedly, if agricultural growth was inclusive. We examine 16 countries for the period 1994-2014 and find that the increase in agricultural productivity is associated with an increase in both non-agricultural employment during the boom. We also find that income per capita growth has been increasing also among the poor, even if the income elasticities are lower in rural than in urban areas. Focusing on the distribution of agricultural income in Brazil and Colombia between 2003 and 2013, we find that any improvement did go through income for the bottom and the intermediate deciles. Furthermore, formal employment was positively connected to the development of agricultural prices, income improvement of the bottom 40 per cent and the quality of manufacturing exports. In other words, the commodity boom, through agricultural growth, increased linkages across sectors. We conclude that the boom is associated with advances in structural change and moderate inclusive growth rather than mere redistribution.
Olecranon fractures: is nonoperative treatment acceptable in older patients?

Background:The purpose of this paper was to identify the outcomes and acceptability of nonoperative against operative (tension band wire) management of olecranon fractures in patients older than 74 yr. Methods:Retrospective analysis of all adult patients presenting with olecranon fractures over the last 2 yr, with a minimum of 6 mo follow-up. Results:Of 74 patients, 36 underwent tension band wiring, 14 underwent plating, and 24 were managed nonoperatively. Patients with less than 5 mm displacement showed no difference in pain or function between the treatment modes. Those with 5-10 mm of displacement in the older than 74 yr group had significantly lower mean pain scores when managed nonoperatively, 1.28 compared with 4.75 (P=0.0070). They also had numerically worse functional scores, though not significant, 27.25 compared with 9.18 (P=0.0855). Patients with 10-20 mm displacement again showed no significant difference in pain or function between tension band wiring and nonoperative treatment. All patients with displacement of more than 20 mm underwent operative fixation with tension band wiring, however. Mean pain and function scores were generally quite poor in this group in both age ranges. There were 14 reoperations in the tension band wiring group, four of which were in patients older than 74 yr. Conclusions:Nonoperative treatment of displaced olecranon fractures in the older population is an acceptable treatment option avoiding risks of surgery and resulting in low pain and reasonable function, equivalent to tension band wiring.
When the Former CEO Stays on Board: The Role of the Predecessor’s Board Retention for Product Innovation in Family Firms

Understanding product innovation in family firms is an important research endeavor given the economic pre-dominance of those firms, their idiosyncrasies, and the importance of constant renewal for those firms to achieve transgenerational survival. Recently, family firm research has highlighted the role of next-generation chief executive officers (CEOs; i.e., successors) who are often seen as drivers for innovating a family firm’s products. However, prior research has typically neglected that predecessors, who are often portrayed as less willing to introduce product innovation, frequently remain involved postsuccession through occupying board positions and thus still substantially influence the decision-making processes and outcomes of family firms, such as product innovation. As a result, our understanding of the role of predecessors and their postsuccession involvement in family firms’ product innovation remains unclear. Building on stakeholder salience theory and on insights from the literature on innovation and succession in family firms, we develop hypotheses about how and under which conditions the predecessor’s board retention affects product innovation in family firms after succession. Building on more than 200 family firm CEO succession cases in small- and medium-sized, privately owned family firms, our results reveal that the predecessor’s board retention negatively affects product innovation. This negative effect is strengthened with increasing involvement of the predecessor in the successor selection process, and it is offset in the case of family succession. Our findings contribute to the emerging stream of research on family firm succession and product innovation and provide important implications for practice.
Hearing aid fitting: Outcomes for older adults

The aims of this study were to determine the outcomes of hearing aid fitting in an Australian sample of older, first-time hearing aid users and to determine factors associated with outcomes in the sample. Outcomes were measured at three to nine months post-fitting using self-report of hours of hearing aid use, satisfaction with aid/s and benefit obtained from aid/s. The subject sample consisted of 52 people aged from 60 to 97 years. The most common audiometric configuration was a mild to moderate sensorineural hearing impairment and the majority of subjects (86%) were fitted with in-the-ear hearing aids. Results showed that 65% of subjects reported using their hearing aid/s for four or more hours per day, 71% were very satisfied with their hearing aid/s, and all subjects who were using their aids reported some benefit from them. Hearing aid/s were used most often and were of greatest benefit when listening to television or radio and in small group situations. Attitude towards rehabilitation and hearing aids was significantly related to hours of use post-fitting, and motivation for attendance was significantly related to satisfaction with hearing aids postfitting. Poorer outcomes were recorded for subjects who presented with a negative attitude to rehabilitation and who were not self-motivated. These results suggest that hearing aid fitting may not be an appropriate option in such cases and that other management strategies should be adopted.
Selective opposition-like control of large-scale structures in wall-bounded turbulence

We investigate the effect of controlling large-scale, logarithmic-layer turbulent structures, which have a characteristic size and aspect ratio that scale with the distance from the wall. The aim is to quantify the effect of suppressing these structures while leaving the near-wall turbulent dynamics unaltered. By affecting only the logarithmic-layer structures, it might be possible to isolate their contribution to the drag from that of the other scales in the flow. We conduct direct numerical simulations of turbulent channel flows at friction Reynolds number ReT ? s 500-1000 and artificially remove certain streamwise and spanwise wavelengths of the wall-normal velocity across a range of heights. The wavelengths chosen depend on the target height (and size) of the structures that we wish to target. When these wavelengths are removed, we observe a positive, outward shift of the mean velocity profile above the target height, due to a local reduction in Reynolds shear stress, and a subsequent increase in viscous stress. Our preliminary results suggest that this shift in the mean velocity profile scales in outer units.
Fixed-Time Stabilization of a Class of Strict-Feedback Nonlinear Systems via Dynamic Gain Feedback Control

This paper presents a novel fixed-time stabilization control (FSC) method for a class of strict-feedback nonlinear systems involving unmodelled system dynamics. The key feature of the proposed method is the design of two dynamic parameters. Specifically, a set of auxiliary variables is first introduced through state transformation. These variables combine the original system states and the two introduced dynamic parameters, facilitating the closed-loop system stability analyses. Then, the two dynamic parameters are delicately designed by utilizing the Lyapunov method, ensuring that all the closed-loop system states are globally fixed-time stable. Compared with existing results, the “explosion of complexity” problem of backstepping control is avoided. Moreover, the two designed dynamic parameters are dependent on system states rather than a time-varying function, thus the proposed controller is still valid beyond the given fixed-time convergence instant. The effectiveness of the proposed method is demonstrated through two practical systems.
The Role of Job Satisfaction on Employees’ Innovation Performance in the Jordanian Hospitality Industry

Previous research shows many significant links between employees‟ perceptions of their overall satisfaction experience in hotels, and other variables. However, the role of job satisfaction that plays on employees‟ innovation performance in the Jordanian hotels remains relatively unexplored. This research explores the link between employees‟ job satisfaction and employees‟ innovation performance. Previous research has used scales developed in a western contexts and this research aims to be one of the first researches to measure these scales in a non-western context and relevant directly to the Jordanian hotels context. The current research was carried out by measuring the data gathered through a five-point Likert scale and a quantitative approach based on a self-administered questionnaire was used. Therefore, a 45-item questionnaire, measuring job satisfaction and innovation performance, was distributed to 300 employees working in 12 five-star hotels in Jordan with a 62% response rate. The results of exploratory factor analysis presented two-dimension for job satisfaction and one-dimension for innovation performance to be both valid and reliable in the Jordanian hotel context. The results showed that the job satisfaction at five star hotels in Jordan has a positive influence on employees‟ innovation performance. At the dimensional level, the results indicated that operational working system has also a positive influence on employees‟ innovation performance but in contrary to rewarding system which has no influence on employees‟ innovation performance. In general, the relationships of job satisfaction as a whole and at the dimensional level on employees‟ innovation performance have clear implications for both theory and Jordanian hotel management. The results also raised a number of interesting and potentially new areas for future research.
