TVET Teacher Professional Competency Framework in Industry 4.0 Era

Industrial revolution 4.0, which also known as the digital age, is a globalisation era without boundaries. Technological advancement modernises different factors in life and affects many areas, including vocational education. The application of technology in the vocational educational process signifies a shift in the conventional learning paradigm towards more technology-based learning. Therefore, TVET teachers should enhance their competencies to present vocational training that can facilitate future human capital and adapt to new technologies and global challenges in this digital era. A systematic literature review was conducted to investigate TVET Teacher Professional Competency for industry 4.0. Though previous research studies focused on different sets of competencies needed by teachers in industry 4.0, most of them share similar themes. A list of constructs was identified through document analysis. These professional competencies constructs includes technical, non-technical, personal, mental, and physical attributes, as well as motive and self-concept. Each construct was then divided into several related sub-constructs. These findings are then proposed as a framework for developing TVET teacher professional competence in Industry 4.0 era. This study also pointed out that non-technical competency is as important as technical competence and strengthens with teacher personal attributes, their motive, and physical state in the TVET teacher profession. Hence, TVET institutions must open lines for technology adaptability, lifelong learning, and a future set of competencies to meet the challenge of the rapid change in professional competencies requirements for TVET teachers in this digital era.
Closely Mounted UWB MIMO Antenna with Notch Characteristics for Short-Range Wireless Video Transmission Application

ABSTRACT In this paper, we introduce a four-port self-isolated double-sided Ultra Wide Band (UWB) MIMO antenna with WLN notch characteristics for short-range wireless high-definition (HD) video transmission applications. The double side orthogonal arrangement of the radiators is adopted to mitigate the mutual coupling between the four radiators without using an isolation structure. The proposed MIMO antenna design provides a UWB band with the notch characteristics at 5 GHz (4.6–5.9 GHz) by removing tapered rectangular slot. Employing a two-sided structure technique, it achieves an impedance bandwidth of 3.1–13 GHz while keeping isolation above 20 dB and a compact size of . Critical parameters that affect antenna performance, such as bandwidth, surface current, radiation characteristics, envelope correlation coefficient (ECC), peak gain, are being investigated. Also, the proposed simulation and measurement results of the two-sided MIMO antenna show that it is suitable for UWB because of wide impedance bandwidth, radiation pattern, high gain, low ECC, and high isolation. Indoor environment test was conducted using the National Instruments (NI) 802.11 framework to verify the real-time short-range wireless HD video transmission and reception capacity of the proposed MIMO antenna.
Trends and Challenges in Grid-Tied Inverters for Photovoltaic Applications

Grid-Tied inverter has gained the attention of many researchers and power generation industry due to its capability of integrating distributed power generation systems using renewable energy resources with the existing centralized power generation system. Yet the inclusion of a transformer in the Photovoltaic (PV) inverter makes it bulkier, heavier and more expensive. A primary solution to the aforementioned problems is the transformerless PV Grid-Tied inverter. This paper presents a review of different transformerless, single-phase Grid-Tied inverter topologies. The objective of this paper is to study parameters such as leakage current, common-mode voltage, total harmonic distortion, and the efficiency of transformerless Grid-Tied inverters. The paper also provides a discussion on existing Grid-Tied inverter topologies, such as H5, oH5, Novel H5, H5-D, FBDC, H6D2, Hybrid H6, High-efficiency MOSFET H6, Improved H6, 3L H6, H6-A, B, High-Efficiency H6, H6-N, Improved H6, H6-active clamping, Active clamped snubber based H6, Heric, oHeric, Enhanced Heric, Heric-with mid-DC-link, Active clamping, PN-NPC, Improved FBNPC, T-Type 3L, ANPC, HBNPC, NIFB-NPCI, VNIIFBC, M-NPC, Virtual DC bus based inverter, Active Virtual Ground, Type I, Type II, Type III Common Ground, Flying Capacitor and Multilevel Common Ground. Though it is found that many topologies available in the literature, other new topologies can be proposed to improve the performance of the inverter. Furthermore, it is also noted that the performance analysis of the inverter must be carried out in the presence of junction capacitance and shoot-through problem so that new strategies can be introduced in the existing typologies to address these issues.
The discerning of optomechanically induced transparency and Autler-Townes splitting in an optomechanical system

Optomechanically induced transparency (OMIT) which exhibits a transparent window in the absorption spectrum of the optical field has been observed in the optomechanical systems. Autler-Townes splitting (ATS) which describes the coherent superposition of the fields presents also a similar transmission spectrum. Here in this study, we analyze these two effects and find that the performance of OMIT and ATS could be effectively manipulated through the tuning of the coupling rate and the loss rate. We numerically compare the quantity of the two phenomena using the Akaike Information Criterion, the Bayesian Information Criterion and the Hannan-Quinn Criterion, respectively.
Evaluation of the TRPM protein family as potential biomarkers for various types of human cancer using public database analyses

The Transient Receptor Potential Melastatin (TRPM) protein family members have been demonstrated to be involved in a variety of different types of human cancer. However, to the best of our knowledge, there has not yet been a systematic study regarding the mRNA expression of the TRPM protein family or its prognostic value in human cancer. The present study investigated TRPM expression and its prognostic value in various human cancer types via the Oncomine database, Kaplan-Meier plotter, and the PrognoScan and Gene Expression Profiling Interactive Analysis databases. It was revealed that the transcriptional levels of TRPM1, TRPM3 and TRPM6 were decreased in the majority of cancer tissues, while TRPM2 was increased in most cancer types. In addition, the high or low transcriptional levels of the TRPM protein family members were associated with survival outcomes of different types of solid tumors. The present study suggested that certain TRPM protein family members may serve as useful biomarkers for cancer prognosis and anticancer targets for cancer treatment.
Aging and Death in an Organism That Reproduces by Morphologically Symmetric Division

In macroscopic organisms, aging is often obvious; in single-celled organisms, where there is the greatest potential to identify the molecular mechanisms involved, identifying and quantifying aging is harder. The primary results in this area have come from organisms that share the traits of a visibly asymmetric division and an identifiable juvenile phase. As reproductive aging must require a differential distribution of aged and young components between parent and offspring, it has been postulated that organisms without these traits do not age, thus exhibiting functional immortality. Through automated time-lapse microscopy, we followed repeated cycles of reproduction by individual cells of the model organism Escherichia coli, which reproduces without a juvenile phase and with an apparently symmetric division. We show that the cell that inherits the old pole exhibits a diminished growth rate, decreased offspring production, and an increased incidence of death. We conclude that the two supposedly identical cells produced during cell division are functionally asymmetric; the old pole cell should be considered an aging parent repeatedly producing rejuvenated offspring. These results suggest that no life strategy is immune to the effects of aging, and therefore immortality may be either too costly or mechanistically impossible in natural organisms.
Petalonia tatewakii sp. nov. (Scytosiphonaceae, Phaeophyceae) from the Hawaiian Islands

Kogame K. , Kurihara A. , Cho G.Y. , Lee K.M. , Sherwood A.R. and Boo S.M. 2011. Petalonia tatewakii sp. nov. (Scytosiphonaceae, Phaeophyceae) from the Hawaiian Islands. Phycologia 50: 563–573. DOI: 10.2216/10-75.1 A new brown alga Petalonia tatewakii sp. nov. (Scytosiphonaceae) is described from the Hawaiian Islands based on morphological observations and phylogenetic analyses of DNA sequences of the chloroplast-encoded rbcL gene and the ITS1-5.8S-ITS2 region of the nuclear ribosomal cistron. The thalli are linear and complanate, up to 15 cm in length and 0.8 cm in width with rhizoidal filaments in the medulla. This species is morphologically distinguishable from other Petalonia species by having ascocysts among plurilocular zoidangia. Molecular phylogenetic analyses revealed that samples of P. tatewakii form a distinct clade that is sister to the clade of P. binghamiae (J. Agardh) Vinogradova. All our collections of Hawaiian Petalonia from the main Hawaiian Islands were assigned to P. tatewakii.
Evaluation of different methods for the prediction of saturated hydraulic conductivity in tilled and untilled soils

The larger the bulk density of the soil, the smaller the saturated hydraulic conductivity (Ks), however, the relationship between Ks and dry bulk density for tilled and untilled conditions is different. Ks is lower in tilled soil than in untilled soil with the same texture at the same bulk density. The purpose of this study was to compare different models for the prediction of Ks for two soil textures under both tilled and non-tilled conditions. We compred two models based on the non-similar media concept (NSMC-0, NSMC-1), a model based on the similar media concept (SMC) and a model based on the Kozeny equation and Poiseuille law for prediction of Ks (KC-1 and KC-2). This study was conducted at two areas with loam and silty clay loam soils under tilled and untilled conditions. It is concluded that the SMC model is not able to predict Ks under either tilled or untilled conditions. Further, the NSMC-0 model, along with an equation to estimate the shape factor, was able to predict Ks versus dry bulk density for tilled soils. According to our study, under untilled conditions, the KC-1 and NSMC-1 models, and under tilled conditions, the NSMC-1 and NSMC-0 models, predicted Ks accurately. It is concluded that the NSMC models together with the optimized Kozeny–Carman models could reliably be used to predict Ks in different soil textures.
Improved PET/CT Respiratory Motion Compensation by Incorporating Changes in Lung Density

Positron emission tomography/computed tomography (PET/CT) lung imaging is highly sensitive to motion. Although several techniques exist to diminish motion artifacts, a few accounts for both tissue displacement and changes in density due to the compression and dilation of the lungs, which cause quantification errors. This article presents an experimental framework for joint activity image reconstruction and motion estimation in PET/CT, where the PET image and the motion are directly estimated from the raw data. Direct motion estimation methods for motion-compensated PET/CT are preferable as they require a single attenuation map only and result in optimal signal-to-noise ratio (SNR). Previous implementations, however, failed to address changes in density during respiration. We propose to account for such changes using the Jacobian determinant of the deformation fields. In a feasibility study, we demonstrate on a modified extended cardiac-torso (XCAT) phantom with breathing motion—where the lung density and activity vary—that our approach achieved better quantification in the lungs than conventional PET/CT joint activity image reconstruction and motion estimation that does not account for density changes. The proposed method resulted in lower bias and variance in the activity images, reduced mean relative activity error in the lung at the reference gate (−4.84% to −3.22%) and more realistic Jacobian determinant values.
Diversity of endophytic fungi associated with Hedychium spicatum Ham ex Sm. and their antifungal activity against the phytopathogen Alternaria solani

Twenty eight strains of endophytic fungi including sterile mycelia were isolated from the leaf, rhizome and roots of Hedychium spicatum Ham ex. Sm. Majority of the endophytic fungi isolated belonged to the phylum Ascomycota which accounted of about 84%. The endophytic assemblage was dominated by the class Sordariomycetes. Endophytic fungal genera such as Fusarium and Penicillium were found to be common to all the plant parts. Diversity of endophytic fungi was found to be highest in the roots (H’= 2.43). Mucor hiemalis, Penicillium sp. , Penicillium expansum, P. simplicissimum, Phoma medicaginis, Trichoderma sp. and T. gamsii showed above 60% inhibition against the phytopathogen Alternaria solani.
Coverage Based Test Suite Minimization using UML Behavioural Diagrams

There is an important role of software systems testing in the software development cycle. The software testing is used to reveal errors in software which enhances overall quality and efficiency of the software. The approach followed for software testing should be such that it can detect maximum number of errors in minimum time which can lower the effort spent in maintenance phase. Coverage criteria are very important to analyze test cases which can be useful in fault coverage and minimizing the test suite. As it takes a lot of time in the software system testing, so minimizing the test cases can help in minimizing the overall effort required to lower the testing time. Test cases should be selected such that they are covering maximum of activities, basic path and conditions present in the graph and taking less time while executing.
Summer Root Decline

A better understanding of the seasonal dynamics of root activity for creeping bentgrass [Agrostis palustris Huds. = A. stolonifera var. palustris (Huds.) Farw. ] would be beneficial for developing effective breeding and management programs to maximum summer turf quality. The objectives of this study were to examine dynamics changes in root production and mortality for four creeping bentgrass cultivars that differ in summer shoot performance. The study was conducted on a USGA-specification putting green in Manhattan, KS, during 1997 and 1998. The cultivars evaluated were 'L-93', 'Penncross', 'Providence', and 'Crenshaw'. Grasses were mowed daily at 4 mm and irrigated on alternate days. Root production and mortality were monitored using the minirhizotron technique. In both years, total root length and number were highest in August and then decreased in September for all four cultivars. From July to September, the length and number of newly produced roots decreased while those of dead roots increased. The ratio of dead roots to live roots in length and number increased in late summer for all cultivars. While the differences in total root length and number among cultivars were not consistent between 2 yr, Penncross consistently had more dead roots, fewer new roots, and higher root mortality compared with the other cultivars. The results indicate that summer root decline of creeping bentgrass resulted from both decreased new root production and increased root mortality, which could be associated with high soil temperatures during the summer. Variation in root production and mortality may contribute to the differences in shoot summer performance of the four cultivars.
Influence of Nanoscale Surface Arrangements on the Oxygen Transfer Ability of Ceria–Zirconia Mixed Oxide

Ceria-based materials, and particularly CeO2–ZrO2 (CZ) solid solutions are key ingredient in catalyst formulations for several applications due to the ability of ceria to easily cycling its oxidation state between Ce4+ and Ce3+. Ceria-based catalysts have a great soot oxidation potential and the mechanism deeply relies on the degree of contact between CeO2 and carbon. In this study, carbon soot has been used as solid reductant to better understand the oxygen transfer ability of ceria–zirconia at low temperatures; the effect of different atmosphere and contact conditions has been investigated. The difference in the contact morphology between carbon soot and CZ particles is shown to strongly affect the oxygen transfer ability of ceria; in particular, increasing the carbon–ceria interfacial area, the reactivity of CZ lattice oxygen is significantly improved. In addition, with a higher degree of contact, the soot oxidation is less affected by the presence of NOx. The NO oxidation over CZ in the presence of soot has also been analyzed. The existence of a core/shell structure strongly enhances reactivity of interfacial oxygen species while affecting negatively NO oxidation characteristics. These findings are significant in the understanding of the redox chemistry of substituted ceria and help determining the role of active species in soot oxidation reaction as a function of the degree of contact between ceria and carbon.
Antioxidant Properties of Tea Extracts as Affected by Processing

Abstract The changes in the antioxidant properties of green and black tea extracts as a consequence of processing and storage conditions were evaluated through measurements of chain-breaking activity, oxygen scavenging capacity and redox potential. Pasteurisation and storage as well as forced oxygenation in both tea extracts caused an increase in the optical density and a decrease in the reducing power of the beverages; both were accompanied by unexpected increases in the chain-breaking activity of the beverages. Simple model systems containing catechin at a concentration similar to that found in the tea extracts were also considered to simulate the effects of enzymatic browning in tea. Possible explanations for the chain-breaking activity gain observed in the tea extracts as a consequence of processing were proposed.
Assessing the effects of spatial contingency and environmental filtering on metacommunity phylogenetics

Patterns in biodiversity and species coexistence are the result of multiple interacting processes including evolutionary history, trait variation, species interactions, dispersal, environmental variation, and landscape heterogeneity. Exploring patterns of biodiversity across space is perhaps the best integrative method (in contrast to the scarcity of temporal data) to interpret the influence of these multiple and interactive effects in determining community assembly, but it is still underdeveloped. Two emerging fields, metacommunity ecology and community phylogenetics, have been making relevant, though rather independent, progress toward understanding how communities are assembled in space. Our main goals were twofold. First, we described a heuristical framework to merge these two fields into “metacommunity phylogenetics. ” The main goal of this framework is to provide a way to think about how niche properties of species arranged across the environment and different spatial scales influence the process of .
The moderating effects of competitiveness and technological turbulence on the interaction between relational competence and knowledge generation

ABSTRACT The paper purpose is to analyse the antecedents to the generation and dissemination of interorganisational knowledge through the analysis of firms’ relational competence (NetComp), including a moderation test for market environment. The empirical research consisted of a survey with 198 US firms and data were statistically tested using SEM. The results show that firms’ relational competence is more effective in highly competitive environments than in technologically turbulent ones. We also identify a stronger impact of relational competence on knowledge generation than in knowledge dissemination. Theoretical implications shows that market competitiveness and technological turbulence moderate the relationship between firms’ relational competence and generation of knowledge through interorganisational relations and its internal dissemination. For managerial implications, the managers should apply more effort to improve firms’ relational competence in order to access and generate knowledge from partners. Such competences are increasingly relevant since firms may be able to generate knowledge through multiple partnerships.
Characterization of EST‑SSR markers in bread wheat EST related to drought tolerance and functional analysis of SSR‑containing unigenes

Bread wheat (Triticum aestivum) is an important staple food around the world. The enormous volume of the genome of wheat makes it quite slow to progress in traditional scientific research. On the other hand, incessant databases and suitable tools on web sites make progress in wheat research quicker and easier. Drought is a major abiotic stress in accordance with weather changes and accelerated increase in drylands. In this study, 9077 ESTs related to drought tolerance in hexaploid wheat were downloaded from NCBI and assembled into 12062 contigs and 4141 singletons. It was found that trinucleotide had the highest frequency 64.71%. Moreover, 53.80% of SSRs found in coding regions in respect of ORFs. The highest amino acids found for tri-and hexanucleotides were Arginine. In addition, 81% of SSR-containing unigenes had one chromosome location and the highest number of loci was found in chromosomes 1B (69). The distribution of genic SSR loci among the 21 wheat chromosomes, the three subgenomes, and the seven homoeologous groups of wheat chromosomes was significant, with P<0.01 indicating a non-random distribution. Functional annotation and characterization of SSR-containing unigenes have been performed. Eighty-six sequences were identified and sorted into 25 putative TF families and establish 166 pathways using KEGG. Primer-BLAST was used to predict the polymorphism, which was 39% of the 63 primer pairs of SSR markers. Our current study attempts to help farmers in wheat breeding programs to have drought-tolerant accessions, particularly in developing countries.
Quadrature NOMA: A Low-Complexity Multiple Access Technique With Coordinate Interleaving

In this letter, we offer a low-complexity multiple access method based on coordinate interleaving coined as quadrature non-orthogonal multiple access (NOMA). It is shown that by properly utilizing two quadrature carriers, both error performance enhancement and reduction in the number of successive interference cancellation (SIC) operations can be attained as compared to the standard power-domain NOMA approach. Specifically, in a <inline-formula> <tex-math notation="LaTeX">$K$ </tex-math></inline-formula>-user network with single-antenna nodes, the reduction in the number of SIC operations is more than 50% as compared to the original NOMA scheme. When <inline-formula> <tex-math notation="LaTeX">$K=2$ </tex-math></inline-formula>, the power gain obtained by the inspected technique can be as large as 2.5 dB without resorting to any SIC process at all. Further, as compared to the original NOMA idea, the considered approach requires fewer number of SIC stability conditions on power allocation and functions for any power allocation strategy (without an error floor) when <inline-formula> <tex-math notation="LaTeX">$K=2$ </tex-math></inline-formula>. Some similar gains are also applicable for <inline-formula> <tex-math notation="LaTeX">$K>2$ </tex-math></inline-formula>. The decrease in the number of SIC operations manifests itself by boosting the immunity of the system against possible failures during the SIC process.
