Effectiveness of Constructivist Approach Experiments in Teaching Selected Physics Concepts
Authors: Tabago Lorelei C. 
Published: October 2012

The study developed constructivist approach experiments to determine its effectiveness in teaching physics concepts. The quasi-experiment following a non-equivalent control group design was used. Two sections of 2nd year BSIT students of Isabela State University-Cauayan Campus were involved. The study administered pre-test and post-test. The scores in the achievement test and standardized attitude inventory test were compared and the significance of their difference was determined using the t-test. The control group and the experimental group were equal in terms of cognitive level in Physics. However, the students exposed to the constructivist approach of laboratory teaching had significantly higher post-test scores and higher mean gain scores than the students exposed to the traditional approach after the study was conducted. The experimental group developed a more positive attitude towards Physics than the control group. Moreover, there was a significant difference between the post achievement scores and post attitude scores of the students exposed to constructivist approachbased experiments and traditional experiments. The Constructivist Approach Experiments are effective in enhancing students’ achievement and in developing a more positive attitude towards the subject than the traditional approach.

Authors: Pring Cecilia C. , Magnaye Bella P. 
Published: October 2012

A professional help is needed before a person can be declared as mentally ill. It is quite alarming that there are unreported cases of mental illness that needed help but people are afraid to seek consultation for fear of social stigma. This study aimed to assess the level of awareness and utilization of mental health services by caregivers of patients with maladaptive behaviour in Batangas Province. Descriptive type of research was used in this study. Data were collected through the use of a structured questionnaire and interview. The data were analysed using weighted mean. Results indicate that most of the patients with maladaptive behaviour were aged 35-44 years. Majority of them were male coming from the lower socioeconomic level. It was also found out that caregivers were aware of the different health services offered by the Department of Health; however, not all of them were available in the medical institution where they seek consultation. The only government hospital with mental health services in Batangas Province is the Regional Hospital situated in Batangas City. The study concluded that health services which should be available to patients were not fully implemented. Keywords - mental health, maladaptive behaviour, awareness, caregiver, health services

Safety in Indian Coal Mines – Where Do We Go from Here
Authors: Paul Partha Sarathi 
Published: October 2012

The 20th century has experienced a considerable amount of success in coal mine safety in India. The mining industry has for many years focused on injury prevention at the workplace through procedures and training, and has achieved considerable success. However, the statistics on major accident events such as fatalities and reportable incidents has not shown the corresponding levels of improvement. In the area of major hazards control, the mining industry approach has emphasized mainly on past experiences and lessons learnt, while other high hazard industries such as the chemical process industry and oil and gas industry have taken system safety techniques to new highs. A literature review on quantitative analysis of mine safely studies revealed that numerous investigators explored a wide- range of techniques, including the investigation of bivariate and multivariate statistical models. It is inferred that the use of these quantitative techniques can provide a new direction of research in mine-safety studies. The important aspect, which was explored in this study through structural equation modeling, is the sequential interrelationships amongst the personal, social, and technical factors leading to accident/injury causation. Interestingly, the accidentinvolved workers are more job stressed, more job dissatisfied and hence, less job involved and often get bored with their jobs. The level of dissatisfaction in mines is quite expected. Further research should be performed using national data set so that the findings can be generalized to all segments of the mining industry.

Published: October 2012

The need to properly manage watersheds is more pressing now than it has ever been. The increasing demand for water, timber, land, and other valuable watershed resources alongside the worsening negative impacts of local and global phenomena have brought the necessity for sustainable watershed management to a higher level. This study focused on the effectiveness of three upland tenurial programs in Northern Luzon like Community-Based Forest Management (CBFM), Muyung Resource Permit (MRP), and TREE for Legacy (TFL). The study used the descriptive comparative and predictive, quantitative, and qualitative methods of research with structured questionnaire and an interview. The study found that The CBFM and TFL programs were “very effective”. The implementers of TFL and CBFM program have higher degree of competence compared to the muyung resource permit program. The program involvement and participation of the stakeholders from the TFL and CBFM programs were higher than the program involvement and participation of the MRP stakeholders. The TFL and CBFM programs were more effective compared to MRP program. There were five variables that are considered as best predictors of effectiveness of the tenurial programs. These were the “government/institutional support”, “program planning and development”, “capability development”, “program monitoring” and “communication methods and techniques”. Keywords - Muyung Resource Permit, TREE for Legacy, Community-Based Forest Management Program, Ttenurial Progam
A combination of protein phosphatase 2A inhibition and checkpoint immunotherapy: a perfect storm
Authors: Clark Mary C. , Lu Rongze Olivia , Ho Winson S. , Dias Matheus Henrique , Bernards René , Forman Stephen J. 
Published: June 2024

Immune checkpoint blockade has emerged as a potent new tool in the war on cancer. However, only a subset of cancer patients benefit from this therapeutic modality, sparking a search for combination therapies to increase the fraction of responding patients. We argue here that inhibition of protein phosphatase 2A (PP2A) is a promising approach to increase responses to immune checkpoint blockade and other therapies that rely on the presence of tumor‐reactive T cells. Inhibition of PP2A increases neoantigen expression on tumor cells, activates the cGAS/STING pathway, suppresses regulatory T cells, and increases cytotoxic T cell activation. In preclinical models, inhibition of PP2A synergizes with immune checkpoint blockade and emerging evidence indicates that patients who have tumors with mutations in PP2A respond better to immune checkpoint blockade. Therefore, inhibition of PP2A activity may be an effective way to sensitize cancer cells to immune checkpoint blockade and cell‐based therapies using tumor‐reactive T cells.

Published: June 2024

AbstractDielectrics with high‐energy‐storage performance are highly desired for increasing compact‐size energy storage, and integration of modern power electronics. However, an ever‐existing challenge is to achieve both high efficiency (η) and high energy density (Ue). Here, a gradient‐layered (five‐layer) polyetherimide (PEI)‐based nanocomposite is presented. Different from traditional layered structures (modulation of filler volume fraction), multistage gradient interfaces are constructed by modulating the particle sizes of barium titanate nanoparticles (BaTiO3 NPs) to decrease sequentially from top to bottom. In this structure, three BaTiO3 NPs/PEI layers are clamped by two boron nitride nanosheets (BNNSs)/PEI layers. It is demonstrated that the gradient structure can suppress breakdown and confer high interfacial polarization, simultaneously. Consequently, the nanocomposite possesses an enhanced Ue of 16.38 J cm−3, and an ultrahigh η of 97.79%, far exceeding previously reported polymer nanocomposites. Furthermore, this nanocomposite also demonstrates satisfactory high‐temperature energy storage performances, achieving a Ue of 7.36 J cm−3 and an η of 83.12% at 150 °C. This gradient layered structure design opens a new way to explore high‐performance dielectric polymer nanocomposite with both ultrahigh Ue and η.

AbstractElectrochemical Performance of aqueous Zn‐ion batteries (AZIBs) is prominently constrained by poor stability of zinc‐metal anodes. However, the use of conventional aqueous separators unfavorable to the uniform deposition of Zn metal and restricted cell cycle life, has hindered the large‐scale application of such battery systems. Here, a separator with hydrophobic/hydrophilic structural domains (marked as PP‐g‐AA) is reported, where the polypropylene (PP) polymer backbone permits partial blockage of water molecules and prevent side reactions, and the carboxyl functional groups in the grafted acrylic acid (AA) facilitate to well regulate the interfacial electric field and Zn2+ ion concentration field, thus remarkably promotes homogenization of zinc ion flux, achieving dendritic‐free deposition of Zn2+. Moreover, the PP‐g‐AA separator sustains a long‐term cycling over 4000 h at a current density of 2 mA cm−2 with a high Coulombic efficiency of 99.6% achieved in Zn||Cu cells, which if assembled into Zn||Zn0.27V2O5·nH2O (ZVO) cells would yield ≈100% retention for 1000 cycles. This research highlights that the strategy opens up a new avenue based on PP‐g‐AA for further decreasing the cost and promoting the industrial application of AZIBs.
The Effects of Biomimetic Surface Topography on Vascular Cells: Implications for Vascular Conduits
Authors: Conner Abigail A. , David Dency , Yim Evelyn K.F. 
Published: June 2024

AbstractCardiovascular diseases (CVDs) are the leading cause of mortality worldwide and represent a pressing clinical need. Vascular occlusions are the predominant cause of CVD and necessitate surgical interventions such as bypass graft surgery to replace the damaged or obstructed blood vessel with a synthetic conduit. Synthetic small‐diameter vascular grafts (sSDVGs) are desired to bypass blood vessels with an inner diameter <6 mm yet have limited use due to unacceptable patency rates. The incorporation of biophysical cues such as topography onto the sSDVG biointerface can be used to mimic the cellular microenvironment and improve outcomes. In this review, the utility of surface topography in sSDVG design is discussed. First, the primary challenges that sSDVGs face and the rationale for utilizing biomimetic topography are introduced. The current literature surrounding the effects of topographical cues on vascular cell behavior in vitro is reviewed, providing insight into which features are optimal for application in sSDVGs. The results of studies that have utilized topographically‐enhanced sSDVGs in vivo are evaluated. Current challenges and barriers to clinical translation are discussed. Based on the wealth of evidence detailed here, substrate topography offers enormous potential to improve the outcome of sSDVGs and provide therapeutic solutions for CVDs.

AbstractIn this study, the double remnant polarization (2Pr) is enhanced from ≈2 to 25 µC cm−2at a low applied voltage of ±2 V (or from 10 to 35 µC cm−2at a voltage of ±4 V) by decreasing the WNxinterfacial capping layer (ICL) thickness from 6 to 2 nm in a novel Ru/WNxICL/Hf0.5Zr0.5O2(HZO)/TiN structure after annealing at 400 °C in a furnace. This occurs because of the higher orthorhombic (o) plus rhombohedral (r) phases (>70%), which is analyzed by geometrical phase analysis (GPA) of high‐resolution transmission electron microscope (HRTEM) images. An optimized 2 nm WNxICL memory capacitor shows a low coercive field (Ec) of 1.27 MV cm−1and long endurance of > 109cycles (remaining 2Prvalue of 13.5 µC cm−2) under a low field stress of ±2 MV cm−1and 0.1 µs hold pulse width (or ≈1.67 MHz). Even this long endurance of > 109cycles is obtained by applying a higher stress of ±2 MV cm−1, 1 MHz, or 100 kHz. Under ±3 MV cm−1stress, the mechanism is caused by m‐phase growth from both the HZO/TiN bottom electrode (BE) and WNxICL/HZO interfaces, which is evidenced by HRTEM images after 2 × 107cycles for the first time.

Published: June 2024

AbstractSurface decoration of support structures by physical vapor deposition (PVD) of small molecular building blocks offers a versatile platform to realize functional supramolecular nanofibers in a controlled manner and with tailored properties. Here, details on the preparation of surface‐decorated polyamide fabrics by PVD using N1,N3,N5‐tris[2‐(diisopropylamino)‐ethyl]‐1,3,5‐benzenetricarboxamide (1) as a molecular building block are reported. It is shown that a defined morphology with uniform nanofiber length can be achieved, which is controlled by the PVD conditions. The functional periphery of supramolecular nanofibers of 1 allows the immobilization of gold nanoparticles (AuNPs). This results in AuNP‐loaded nanostructures with a high surface area, which can be used as a heterogenous catalyst for the reduction of 4‐nitrophenol in aqueous media. The surface‐decorated support structures with firmly deposited AuNPs also provide the opportunity to conveniently reuse these structures without compromising the catalytic performance. This approach provides fabrication strategies for the controlled surface decoration of macroscopic support structures with small molecular building blocks by PVD with the potential to realize functional robust supramolecular nanofibers for various catalytic or filtration applications.
