Parental Style and Academic Achievement in Mts Ittihadul Muslimin Siak Students

Pangkalan Pisang Village is located in the Koto Gasib District of the Siak Regency in the Indonesian province of Riau and the study was carried out there. The aim of this research was to determine whether or not there was a relationship between parenting styles and student learning accomplishments in second grade (class 2). Students at MTs Ittihadul Muslimin will be asked to respond to a questionnaire, and the results will be compiled. When this performance is reduced, it indicates the necessity of developing classroom instructional techniques that include academic components, social relationships and conduct as well as other factors. Immediate summaries of student accomplishments, as well as measures to enhance student participation, motivation, and success, should be provided. Thus, personality differences and students' skills are less significant than they were previously believed. In the absence of consideration for the connection between student cognitive types, parents develop their own parenting styles, with the consequence that parenting styles and learning are the outcome of the style of parents and students'. Researchers Omar et al (2012) found that parental influence is the most important factor in a child's development as a human being. Diana Baumrind is credited with developing the parenting style model (Omar et al., 2012). As he explained it, there are three types of parenting techniques that may be used to shape children's early development. Parents who practice autority, authoritarian parenting, and permissive parenting are examples of parenting styles that are related to the authorization style. Measurements of the average and standard deviation are used to characterize the respondent profile and to answer research questions using descriptive statistical analysis. According to this research, the most prevalent parenting style is autiithative. Thus, the appropriate parenting style is the most apparent in the parenting styles of all tribes, including Malay, Minang, Java and Batak families. Because it does not fully understand the parenting style of each individual, his understanding is that the parenting style of Diana
On the Use of Large Interactive Displays to Support Collaborative Engagement and Visual Exploratory Tasks

Large interactive displays can provide suitable workspaces for learners to conduct collaborative learning tasks with visual information in co-located settings. In this research, we explored the use of these displays to support collaborative engagement and exploratory tasks with visual representations. Our investigation looked at the effect of four factors (number of virtual workspaces within the display, number of displays, position arrangement of the collaborators, and collaborative modes of interaction) on learners’ knowledge acquisition, engagement level, and task performance. To this end, a user study was conducted with 72 participants divided into 6 groups using an interactive tool developed to support the collaborative exploration of 3D visual structures. The results of this study showed that learners with one shared workspace and one single display can achieve better user performance and engagement levels. In addition, the back-to-back position with learners sharing their view and control of the workspaces was the most favorable. It also led to improved learning outcomes and engagement levels during the collaboration process.
Lightning stroke simulation by means of the leader progression model. II. Exposure and shielding failure evaluation of overhead lines with assessment of application graphs

For pt.I see ibid., vol.5, no.4, p.2009-22 (1990). To evaluate the lightning performance of transmission lines, extensive application of the leader progression (LP) model to the relevant geometrical configurations has been carried out. Basic configurations used in the LP computer program are presented together with the method of analysis of the lightning exposure of transmission lines located in the different orographic conditions of flat countries, ridges of hills, and along a mountain side. A computer program used to evaluate shielding efficiency and the total number of strokes to the line is considered. A set of application graphs referring to the different orographic locations and including wide ranges of line heights, shielding angles, and insulation levels are given. >
Analysis of the sign reversal of the photodetected signal response in a multielectrode semiconductor optical amplifier

We present a theoretical analysis and experimental results for a two-electrode (200 /spl mu/m/spl times/300 /spl mu/m) 1.5-/spl mu/m semiconductor optical amplifier (SOA) used in photodetection. The experimental results show that at a particular operating point regarding current and optical input power, a sign reversal of the photodetected signal response, and a frequency bandwidth shape modification are obtained at the SOA front contact. These results are confirmed by simulation and explained by the developed theoretical photodetection expression obtained by small signal analysis from the rate equation.
Approaches for enhancing information sharing between government and communities in Western Cape

Background: The Western Cape Provincial Government uses digital intermediaries to facilitate information sharing between individuals, communities and the government. Digital intermediaries are shared facilities where communities can visit and have access to information and communication technology (ICT) and the internet. Communities benefit economically, socially and politically by using free access to ICT and the internet from intermediaries’ facilities to share information with the government. There seem to be disparities between the roles of the different stakeholders in information sharing. These disparities often result in poor communication between the government and communities, and also poor government services delivery.Objectives: This research investigated how intermediaries can enhance information sharing between government and communities in the Western Cape Province.Method: This study adopted a qualitative research approach by using semi-structured interviews. Purposive sampling was used to collect qualitative data from 15 participants from different intermediaries’ staff in the Western Cape Province. A narrative analysis approach was used to analyse the data.Results: The study found that intermediaries intermediate between communities and the government by providing free access to ICTs, provide basic computer training and access to computing resources and serving as an information hub. The study also found that operating hours, lack of resources, skilled staff and communication challenges adversely affect information sharing.Conclusion: This study recommended that intermediaries are supported to increase the number of resources and facilities and the number and levels of training in the province to cater for more communities. This study further recommended an increase on operational hours, and communication channels between the government and intermediaries.
The Prevalence of Child Restraint System Use among Children in Vehicles Equipped with Front Passenger Airbag in Kajang, Malaysia

New cars are being introduced with front passenger airbags (PAB) as a standard safety feature. Airbags are designed to reduce vehicle occupant injury in the event of a collision. In order for airbags to be effective, occupants must be restrained while travelling in vehicles. Children are often seen unrestrained while travelling in vehicles throughout Malaysia. Studies have shown that unrestrained children are exposed to higher risk of injury in a crash involving PAB deployment, compared to those who are restrained. The intended life saving benefit of PAB may be negated if child occupants remain mostly unrestrained. The objective of the study is to determine the prevalence of child restraint system (CRS) use in vehicles, especially those equipped with PAB. To realise this, an observational survey was conducted at selected day care centres in Kajang, to determine the use of child restraints among children aged six and below, child seating position, driver seatbelt use and availability of PAB. The study was performed in the first half of 2012. A total of 537 children aged 6 and below were observed. 51.4% of the children were seated in the front passenger seat, 45.3% were seated in the rear and 3.3% were seated on the driver’s lap. 13.3% of children seated in front seats were restrained, compared to 4.9% of those seated at the rear. Children were 4 times more likely to be restrained if the drivers were belted compared to those who were not. In vehicles equipped with PAB, 11.2% of children seated on the front seats are restrained, while in vehicles without, 17.1% were restrained. The restraint use among children is low and the presence of PAB does not have a significant effect on the use of CRS. There was a significant association between belted drivers and restrained children. The low CRS use is expected as the current legislation does not specifically mention the requirement for children to use CRS while travelling in vehicle, even if the vehicle is equipped with PAB.
Nonlinear full-wave-interaction analysis of a gyrotron-traveling-wave-tube amplifier based on a lossy dielectric-lined circuit

The stability of the millimeter-wave gyrotron-traveling-wave-tube (gyro-TWT) amplifier can be effectively improved via controlling the propagation characteristics of the operating modes using lossy dielectric-lined (DL) waveguide. Self-consistent nonlinear theory of the electron cyclotron maser (ECM) interaction in lossy DL circuit is developed based on a full-wave study of the propagation characteristics of the DL waveguide. This nonlinear theory fully takes into consideration the waveguide structure and the lossy dielectric characteristics. It is capable of accurately calculating the ECM instability between a cyclotron harmonic and a circular polarized mode, and effectively predicting the nonlinear stability of the DL waveguide-based gyro-TWT. Systematic investigation of a Ka-band TE01 mode DL waveguide-based gyro-TWT is carried out, and numerical calculation reveals a series of interesting results. This work provides a basic theoretical tool for further exploring the application of the lossy DL wavegui.
Short circuit properties of Trench-/Field-Stop-IGBTs-design aspects for a superior robustness

This paper will discuss the different principal short circuit failure modes of IGBTs focusing on the new Trench-/Field-Stop-IGBT device concept. Beside the short circuit robustness limitation regarding an over temperature destruction, a new failure mode, the so called short circuit current destruction mode, is described. Necessary design aspects for Trench-/Field-Stop devices resulting in a superior short circuit robustness at least as good as the well established Non Punch Through IGBTs - are derived and proved experimentally by extreme single (e.g. Tj=200/spl deg/C! ) and repetitive short circuit pulse tests (e.g. 50.000 times).
Modeling Hygro-thermal Performance and Strains of Cementitious Building Materials Maturing in Variable Conditions

A novel model of hygro-thermal performance of cement-based building materials during their maturing, considering evolution of their strength properties and deformations (shrinkage and creep strains), described in terms of effective stress is briefly presented. Creep is described by means of the modified microprestress — solidification theory by Bazant et al., with some modifications to take into account the effects of temperature and relative humidity on the cement hydration. Shrinkage strains are modeled by using effective stresses in the form introduced by Gray and Schrefler, giving a good agreement with experimental data also for low values of relative humidity. Results of three numerical examples based on the real experimental tests are solved to validate the model. They demonstrate its possibilities to analyze both autogenous deformations in maturing cementitious materials, and creep and shrinkage phenomena, in building elements of different age, sealed or drying at various conditions.
Testing and modeling of square carbon fiber‐reinforced elastomeric seismic isolators

Steel‐reinforced elastomeric isolators (SREIs), as an effective seismic isolation device, are the most common isolators in use. However, SREIs are typically heavy and expensive and, as a result, application of these devices is often limited to large and expensive structures. A reduction in the cost and weight of elastomeric isolators would permit a significant increase in their application to many ordinary residential and commercial buildings. Fiber‐reinforced elastomeric isolators (FREIs) are a new type of elastomeric bearing that employs fiber as the reinforcement material rather than steel. FREIs have several advantages over traditional SREIs including superior damping properties, lower manufacturing cost, light weight, and the possibility of being produced in long rectangular strips with individual isolators cut to the required size. This paper presents a brief literature review on experiments with FREIs, and reports on an experimental study conducted on carbon FREIs from which the mechanical properties of the bearings, including displacement characteristics and damping values are evaluated. A brief description of an analytical approach to model the cyclic response of the bearings is another component of this paper. As a special application, the bearings considered in this study were not bonded to the test platens. For bearings having suitable aspect ratio values, this particular type of application resulted in a stable rollover deformation, which reduced the horizontal stiffness and increased the efficiency of the bearing as a seismic isolator device. Test results suggest that for many high seismic risk regions worldwide, the application considered in this study can be viable for the base isolation of ordinary low‐rise buildings.

Association of Serum Neurofilament Light Chain Concentration and MRI Findings in Older Adults

Background and Objectives Neurofilament light chain (NfL) in blood is a sensitive but nonspecific marker of brain injury. This study sought to evaluate associations between NfL concentration and MRI findings of vascular brain injury in older adults. Methods A longitudinal cohort study included 2 cranial MRI scans performed about 5 years apart and assessed for white matter hyperintensities (WMH) and infarcts. About 1 year before their second MRI, 1,362 participants (median age 77 years, 61.4% women) without a history of TIA or stroke had measurement of 4 biomarkers: NfL, total tau, glial fibrillary acidic protein (GFAP), and ubiquitin carboxyl-terminal hydrolase L1. Most (n = 1,279) also had the first MRI scan, and some (n = 633) had quantitative measurements of hippocampal and WMH. In primary analyses, we assessed associations of NfL with a 10-point white matter grade (WMG) and prevalent infarcts on second MRI and with worsening WMG and incident infarct comparing the 2 scans. A p value <0.0125 (0.05/4) was considered significant for these analyses. We also assessed associations with hippocampal and WMH volume. Results In fully adjusted models, log2(NfL) concentration was associated with WMG (β = 0.27; p = 2.3 × 10−4) and worsening WMG (relative risk [RR] 1.24; p = 0.0022), but less strongly with prevalent brain infarcts (RR 1.18; p = 0.013) and not with incident brain infarcts (RR 1.18; p = 0.18). Associations were also present with WMH volume (β = 2,242.9, p = 0.0036). For the other 3 biomarkers, the associations for log2 (GFAP) concentration with WMG and worsening WMG were significant. Discussion Among older adults without a history of stroke, higher serum NfL concentration was associated with covert MRI findings of vascular brain injury, especially the burden of WMH and its worsening. Whether these results offer opportunities for the use of NfL as a noninvasive biomarker of WMH or to control vascular risk factors remains to be determined.
Anti-inflammatory and neuroprotective activity of Viphyllin a standardized extract of β-caryophyllene from black pepper (Piper Nigrum L) and its associated mechanisms in mouse macrophage cells and Human Neuroblastoma SH-SY5Y cells

Oxidative stress breeds various chronic lifestyle ailments including inflammatory conditions and neurodegenerative diseases. β-caryophyllene natural bicyclic sesquiterpene, obtained from various plants sources found to be effective against inflammation and neuroprotection. In this study, we have evaluated the protective effect of Viphyllin, a standardized extract of β-caryophyllene from black pepper against inflammation induced by lipopolysaccharide in RAW264.7 macrophage cells and mechanisms involved in hydrogen peroxide (H2O2)-challenged oxidative stress in human neuroblastoma SH-SY5Y cells. Viphyllin demonstrated the anti-inflammatory activity by subsiding the release of the pro-inflammatory intermediaries like NO, cytokines, interleukins, and protein expression levels of cyclooxygenase (COX-2) and inducible nitric oxide synthase (iNOS). In addition, Viphyllin suppressed the extracellular signal-regulated kinase (ERK). c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK) phosphorylation. On the other hand, Viphyllin showed neuroprotective effect against neuronal oxidative damage caused by H2O2. Viphyllin lessened the expression B-cell lymphoma-2 (Bcl-2), B-cell lymphoma-2-associated X protein (BAX), cleaved caspase-9, and PARP-1 proteins associated with apoptosis. Our results indicate that Viphyllin ameliorated LPS-mediated inflammation in macrophages by regulating inflammation and Viphyllin exerted remarkable anti apoptotic effect against neuronal damage challenged by H2O2. Altogether, Viphyllin could be potential functional food ingredient for inflammation and neurodegenerative diseases.
Effect of casting sequences on the restraint in slab-on-ground

One of the widespread issues in concrete structures is cracks occurring at early age. Cracks that appear in the young concrete may cause early start of corrosion of rebars or early penetration of harmful liquids or gases into the concrete body. These situations could result in reduced service life and in significantly increased maintenance cost of structures. Therefore it is important for construction companies to avoid these cracks. Restraint represents one of the main sources of thermal and shrinkage stresses at early age concrete. The casting sequence is affected by the restraint from adjacent structures. The present study discusses the influence of five casting sequences for the typical structure slab-on-ground. The aim is to map restraints for a number of possible casting sequences, and to identify the sequence with the lowest restraint. The study covers both continuous and jumped casting sequences, which include one, two and three contact edges. The result shows that the best casting sequence is the continuous technique with one contact edge
Dynamics of transitions between capillary stable states under weightlessness

Srikanth, Praveen MSAA, Purdue University, May 2015. Dynamics of Transitions between Capillary Stable States under Weightlessness. Major Professor: Steven H. Collicott. The study of two phase systems with one of the phases obstructing the other is of importance in a lot of fields. Liquid droplets in airways and air bubbles in the blood stream both fall under this category of problems. Helium bubbles in hydrazine fuel lines of satellites also have been found to cause frequent thruster shutdown and also seriously affect spacecraft control. Studies have been carried out until now to look at static equilibrium topologies and stability of such two phase systems in straight, bent and laterally compressed capillaries. In this investigation we look at the dynamics of the transitions between the stable topologies identified for a straight cylindrical capillary. The break up of the interface could adversely affect system performance. OpenFOAM is used to compute transitions from a stable droplet to a plug or the reverse by suitably adding or removing the obstructing phase through inlet patches on the wall of the cylinder. The main parameters presented are the non-dimensional energy, non-dimensional transition times, non-dimensional transition volumes and the general dynamics of the transitions itself. Before computing transitions the static equilibrium topologies computed by OpenFOAM are compared with those predicted by Surface Evolver and are found to be within acceptable deviations. The grid dependence of these transitions has also been studied. Transitions are computed for contact angles in the range of 10◦ to 170◦. Different modes of transitions are observed depending on the contact angle of the case for both the types of transitions. The transition volumes are compared to the volume of existence limits for the corresponding initial topology at a particular contact angle for both the transitions.
Ethnographic findings in the organizational theatre

In the quest for engaging ethnographic insight in organizations on a more fundamental level than mere ‘innovation drivers’, theatre offers ways of triggering a change in conversations through emotional engagement. This paper discusses the impact of using theatre with professional actors to convey the outcome of ethnographic ‘user studies’ to industry and academia. In a project on indoor climate control with five company partners, the field studies brought about controversial findings, like ‘Indoor comfort is what people make’– as opposed to something fully controlled by technology and ‘provided’ to inhabitants. We explore how theatre improvisation can convey such findings and thus support the provoking role that ethnography may play in organizations. Based on the study of two theatre sessions, we will articulate the importance of balance between playful and serious, of explorative discussion, and of supportive event planning and space layout to achieve audience engagement.
On-Demand Drug Delivery Systems Using Nanofibers

On-demand drug-delivery systems using nanofibers are extensively applicable for customized drug release based on target location and timing to achieve the desired therapeutic effects. A nanofiber formulation is typically created for a certain medication and changing the drug may have a significant impact on the release kinetics from the same delivery system. Nanofibers have several distinguishing features and properties, including the ease with which they may be manufactured, the variety of materials appropriate for processing into fibers, a large surface area, and a complex pore structure. Nanofibers with effective drug-loading capabilities, controllable release, and high stability have gained the interest of researchers owing to their potential applications in on-demand drug delivery systems. Based on their composition and drug-release characteristics, we review the numerous types of nanofibers from the most recent accessible studies. Nanofibers are classified based on their mechanism of drug release, as well as their structure and content. To achieve controlled drug release, a suitable polymer, large surface-to-volume ratio, and high porosity of the nanofiber mesh are necessary. The properties of nanofibers for modified drug release are categorized here as protracted, stimulus-activated, and biphasic. Swellable or degradable polymers are commonly utilized to alter drug release. In addition to the polymer used, the process and ambient conditions can have considerable impacts on the release characteristics of the nanofibers. The formulation of nanofibers is highly complicated and depends on many variables; nevertheless, numerous options are available to accomplish the desired nanofiber drug-release characteristics.
