THE EFFECTS OF ACTION-BASED ENTREPRENEURSHIP EDUCATION ON AMBIGUITY TOLERANCE AND ENTREPRENEURIAL ALERTNESS

The impact of Entrepreneurship Education (EE) programs on elements of the entrepreneurial mind-set remains a subject that is largely under-researched. It is the purpose of this study to examine the effects of an action-based EE program on the development of an entrepreneurial mind-set by testing the effect of the EE program on ambiguity tolerance and entrepreneurial alertness. In a pre-experimental design setting data was collected from a group of 53 graduate students that participated in a 3-months EE program at a European business school. Variables on entrepreneurial alertness and ambiguity tolerance were measured both before the treatment and afterwards using an online survey. The participation in the action-based EE program led to a significant increase in ambiguity tolerance. Furthermore, students who participated in the program developed a better ability of evaluation and judgment of entrepreneurial opportunities, which forms an important part of entrepreneurial alertness. Nevertheless, this study did not find a significant change of overall entrepreneurial alertness as well as in the two elements alert scanning and search and alert association and connection.
b -Lactamases: A Focus on Current Challenges

b -Lactamases, the enzymes that hydrolyze b -lactam antibiotics, remain the greatest threat to the usage of these agents. In this review, the mechanism of hydrolysis is discussed for both those enzymes that use serine at the active site and those that require divalent zinc ions for hydrolysis. The b -lactamases now include . 2000 unique, naturally occurring amino acid sequences. Some of the clinically most important of these are the class A penicillinases, the extended-spectrum b -lactamases (ESBLs), the AmpC cephalosporinases, and the carbape-nem-hydrolyzing enzymes in both the serine and metalloenzyme groups. Because of the versatility of these enzymes to evolve as new b -lactams are used therapeutically, new approaches to antimicrobial therapy may be required.
A Al 2 O 3 Coating Layer on the High Temperature Conductive Stability of Pt/ZnO/Al 2 O 3 Film

China) Abstract: To investigate the effects of Al 2 O 3 coating layers on the conductive stability of surface acoustic wave electrodes working at high temperature, laser molecular beam epitaxy was carried out to deposit a series of Al 2 O 3 /Pt/ZnO/Al 2 O 3 multilayer electrodes coated with Al 2 O 3 layers of different thicknesses. The real-time resistance measurements of these samples were performed in the heat treatment. It can be found that the conductive stabilities of Al 2 O 3 /Pt/ZnO/Al 2 O 3 samples were significantly related to the thickness of the Al 2 O 3 coating layers. For the sample without Al 2 O 3 coating layer, its resistance began to increase when the temperature rose up to 800 ℃ . However, its resistances began to increase at 900, 1100 and 1150 ℃ , at the thickness of Al 2 O 3 coating layers of 40, 80 and 120 nm re-spectively. For the samples with 160 nm and 200 nm Al 2 O 3 coating layers, the resistances almost remained stable dur-ing the whole heating process. According to the surface topographies of these samples, it found that the sample without Al 2 O 3 coating layer formed isolated Pt grains after high-temperature measurement. As a comparison, the samples with Al 2 O 3 coating layers did not form could inhibit its recrystallization more effectively. These results provide a new way to prepare SAW devices which can work stably at high temperature.
BIOCONVERSION OF PLANT BIOMASS TO ETHANOL

Two approaches to ethanol production via thermophilic mixed culture fermentation of pretreated wood were investigated. The initial studies of wood biodelignification by Chrysosporium pruinosum and subsequent mixed culture fermentation to ethanol using a cellulolytic strain of sporocytophaga and a strain of Bacillus stearothermophilus proved to be premature for a development effort. Studies of the fermentation of S02/steamtreated poplar by a mixed culture of C. thermocellum and C. thermosaccharolyticum were, however, technically and economically promising. Wood pretreatment to enhance microbial utilization, the microbiology and biochemistry of pure and mixed culture fermentation of cellulose by C. thermocellum and C. thermocellum and C. thermosaccharolyticum, and techniques for improving ethanol tolerance and yield were investigated. Considerable progress in overcoming the technical barriers to efficient ethanol production from wood have been demonstrated; however, additional studies and development work are required before technical feasibility can be established.
Impact of the coupling effect and the DC-combining configuration on a compact rectenna array

This paper proposes an experimental study of the coupling effect of a rectenna array. The rectifying antenna consists of a compact and efficient rectifying circuit in a series topology, coupled with a small metamaterial-inspired antenna. The measurements are investigated in the X plane on the behavior of rectenna array, with series and parallel DC-combining configuration of two and three spaced rectennas from 3cm to 10cm. This study shows that the maximum efficiency is reached for the series configuration, with a resistive load of 10k Ω . The optimal distance is not significant for series or parallel configuration. Then, a comparison between a rectenna array with non-optimal mutual coupling and a more traditional patch rectenna is performed. Finally, a practical application is tested to demonstrate the effectiveness of such small rectenna array.
Collapse of a desert bird community over the past century driven by climate change

Climate change has caused deserts, already defined by climatic extremes, to warm and dry more rapidly than other ecoregions in the contiguous United States over the last 50 years. Desert birds persist near the edge of their physiological limits, and climate change could cause lethal dehydration and hyperthermia, leading to decline or extirpation of some species. We evaluated how desert birds have responded to climate and habitat change by resurveying historic sites throughout the Mojave Desert that were originally surveyed for avian diversity during the early 20th century by Joseph Grinnell and colleagues. We found strong evidence of an avian community in collapse. Sites lost on average 43% of their species, and occupancy probability declined significantly for 39 of 135 breeding birds. The common raven was the only native species to substantially increase across survey sites. Climate change, particularly decline in precipitation, was the most important driver of site-level persistence, while habitat change had a secondary influence. Habitat preference and diet were the two most important species traits associated with occupancy change. The presence of surface water reduced the loss of site-level richness, creating refugia. The collapse of the avian community over the past century may in-dicate a larger imbalance in the Mojave and provide an early warning of future ecosystem disintegration, given climate models unanimously predict an increasingly dry and hot future.
Effectiveness of chitosan from crab shell as antibiotic for Escherichia coli

Background: Research in finding a safe, effective and natural ingredient against Escherichia coli continues to be carried out as a result of an increasing antibiotic resistance. Chitosan has been known as a food preservative but the research for its effectivity against Eschericia coli is still inadequate. Indonesia is rich of natural animal resources including crustaceans, like Crab. Objective: How effective are chitosans extracted from crab shells as an antibiotic against Escherichia coli when compared with ceftriaxone. Method : Experimental method with a static group comparison where E. coli in Mueller Hinton Agar (MHA) on petri dishes was given chitosan intervention with initiating concentrations starting from 4% to 8% and 30mcg of ceftriaxone given by diffusion. The antimicrobial of E.coli was measured with Whatman paper and standard calipers measured in millimeters. Result : Results of normality and homogeneity variance tests with (p>0,05) were inhomogenous and not distributed normally so it was analyzed with Kruskal Wallis Test continued with a Mann Whitney Test. Conclusion : Chitosan solution extracted from crab shells with concentrations of 4%, 5%, and 6% have an antibiotic effect against the growth of E.coli . The most effective concentration to inhibit E.coli is 4%.
Maxim Violation by Indonesian Government Officials with Different Cultures in Mata Najwa Talk Show Berlin Sibarani

This research aimed at describing the violation of Grice Maxim‟s Cooperative Principle by the three government officials in Mata Najwa Talk Show and to seek out if the assumption of the different culture would be the reason why the subjects violated the maxim. To achieve the purpose, this research was designed with descriptive qualitative. Its data were collected with documentary techniques in which the data were collected from the utterances between the host and the subjects in Mata Najwa Talk Show videos. To analyze the data Miles‟ and Huberman analysis model was applied.The results of the research showed that, not all of the officials violated the maxims. LBP violated all of the maxims, but JK did not, he violated only maxim of quantity, quality and relevance. JW did not violate all the maxim either. He violated only maxim of relevance and maxim of quantity. The matrices showed that the different choice of what maxim to be violated was caused by their different culture. In the violation of more than one maxims, the three government officials did the violation in different sequence. LBP firstly obeyed the M.of Rl and violated the M.of Qn, Meanwhile JK tends to violated M.of Qn and violated M.of Rl and Jokowi violated the M.of Rl and obeying the M.of Qn. This differences were due to the factor of social status, culture, education experience and their awareness of the communication format of talk show, in which the participants are of three partied, namely host, guest, and TV audience all over Indonesia.
Research Report EMOTIONAL INTELLIGENCE, PERCEIVED STRESS, AND INTERNET USE BEHAVIOUR AMONG UNDERGRADUATE MEDICAL STUDENTS-A CROSS-SECTIONAL STUDY

Aim: To find the pattern and characteristics of Problematic internet use and to determine the relationship between Internet Addiction, Perceived stress and Emotional Intelligence among medical students. Materials and methods: In this cross-sectional study, using convenience sampling, 368 study participants were selected from the undergraduate medical students of a medical college in North Kerala. After getting written informed consent, socio-demographic data sheet, Internet Addiction Test (IAT), Schutte Self Report Emotional Intelligence Test (SSEIT) and Perceived Stress Scale (PSS) were filled up by the participants. Completed responses were scored and analyzed using SPSS 18.0. Results: Problematic internet use among the participants was 65.7%. In the sample, 42.9% had mild internet addiction, and 22.8% had moderate internet addiction. There was a positive correlation between scores of IAT and PSS and a negative correlation between scores of IAT and SSEIT. A pattern of increased levels of perceived stress and decreased levels of emotional intelligence was noticed with increasing levels of internet addiction scores. Conclusion: Young medical students were found to have mild and moderate levels of internet addiction and were high in perceived stress. Those with an addiction pattern of internet use also showed lower levels of emotional intelligence. It is crucial to identify those with lower levels of emotional intelligence and intervene effectively for stress management to reduce the internet overuse and emotional sequelae of it.
INNOVATION IN THE REVERSE SUPPLY CHAIN OF ELECTRICAL AND ELECTRONIC WASTE: A STUDY ON INFORMATION SYSTEMS AND TRACKING TECHNOLOGIES

In this study, the contribution of information systems and tracking technologies to the reverse logistics of electronic and electrical waste chains is analyzed. The research was based on a case study in the Brazilian context, incorporating the electronics supply chain. The results show that reverse logistics do not use the technologies and systems implemented in direct logistics. Although tracking technologies can make disassembly and recycling more efficient, the possibility of increased costs remains, and does not contribute to increased sales and profitability. Furthermore, resistance by representatives of the electronics sector to adhere to the sectoral agreement—established by the National Solid Waste Policy (NSWP) in 2010 but signed only at the end of 2019—contributed to companies postponing investments in information systems and technologies tracking in Brazil.
REVIEW OF METHODS FOR SIZE AND MORPHOLOGY DETERMINATION OF VESICLES IN NIOSOME DISPERSION

(in English). doi: 10.17586/2226-1494-2020-20-3-377-381 Abstract The paper provides comparative analysis of direct and indirect methods for assessing the size and morphological characteristics of niosome dispersions. Niosome sizes vary over a wide range: from 20 nm to 10 μm and more. The vesicle shape can also vary from perfectly spherical to elliptical and complexly curved in the case of aggregation. The size and shape of large particles with a diameter greater than 1 μm can be assessed by light microscopy. To study smaller vesicles, about 0.1–0.5 μm, it is advisable to use the technique of dynamic light scattering. Photometric method is reasonable to be used for an indirect assessment of the size of niosome vesicles in the range of 40–130 nm. For surface morphology study of the smallest niosomes, the method of scanning electron microscopy seems to be optimal.
Time to Diagnosis How to Improve Time to Diagnosis in Acute Heart Failure – Clinical Signs and Chest X-ray

pump adequate blood to provide for the needs of the body. ” 12 In UK clinical practice, the term is generally taken to describe the rapid onset of the symptoms and signs of HF occurring over hours to days; typically resulting in hospital admission. Conversely, AHF has also been used to in reference to any patient with HF requiring hospital admission. The latter term confusingly encompasses a different patient population by including those with a subacute or chronically progressive time course. Either may reflect a ‘decompensation’ of known HF, or a de novo presentation in a patient previously undiagnosed. In reality, the clinical features of AHF result from a heterogeneous group of syndromes with significant overlap reflecting multiple underlying aetiologies, of which only around 50 % have a reduced left ventricular (LV) ejection fraction (EF) (see Table 1 ). 16 The clinical severity may vary in accordance with the particular syndrome, (e.g. from predominant peripheral oedema to cardiogenic shock), or dependent on the individual patient; while certain presentations require specific treatments delivered in a time-critical manner (e.g. HF with an acute coronary syndrome). For optimal management, therefore, it is essential that the assessing clinician is able to elicit and interpret the clinical history and physical Abstract Acute heart failure (AHF) is a leading cause of hospitalisation in developed nations with stubbornly poor outcomes in both the short and long term. Furthermore, alongside an ageing population the incidence continues to increase. Contemporary practice guidelines accordingly emphasise the importance of early recognition of heart failure in the acute setting to facilitate the timely instigation of key investigations, appropriate management and access to specialist care; all of which improve outcome. However, the diagnosis of AHF is often challenging, with no gold standard diagnostic test and presenting clinical features that may be non-specific, particularly in the elderly where they may be atypical, or masked by co-morbidity. This short review explores the main clinical signs and radiographic changes in patients with AHF relevant to clinical practice in accordance with the best available evidence.
Alterations in Ca cycling by lysoplasmenylcholine in adult rabbit ventricular myocytes

Liu, Shi J., Richard H. Kennedy, Michael H. Creer, and Jane McHowat. Alterations in Ca2 cycling by lysoplasmenylcholine in adult rabbit ventricular myocytes. Am J Physiol Cell Physiol 284: C826–C838, 2003. First published November 27, 2002; 10.1152/ajpcell.00465. 2002. —We previously reported that lysoplasmenylcholine (LPlasC) altered the action potential (AP) and induced afterdepolarizations in rabbit ventricular myocytes. In this study, we investigated how LPlasC alters excitation-contraction coupling using edge-motion detection, fura-PE3 fluorescent indicator, and perforated and whole cell patch-clamp techniques. LPlasC increased contraction, myofilament Ca2 sensitivity, systolic and diastolic free Ca2 levels, and the magnitude of Ca2 transients concomitant with increases in the maximum rates of shortening and relaxation of contraction and the rising and declining phases of Ca2 transients. In some cells, LPlasC induced arrhythmias in a pattern consistent with early and delayed aftercontractions. LPlasC also augmented the caffeine-induced Ca2 transient with a reduction in the decay rate. Furthermore, LPlasC enhanced L-type Ca2 channel current (ICa,L) and outward currents. LPlasC-induced alterations in contraction and ICa,L were paralleled by its effect on the AP. Thus these results suggest that LPlasC elicits distinct, potent positive inotropic, lusitropic, and arrhythmogenic effects, resulting from increases in Ca2 influx, Ca2 sensitivity, sarcoplasmic reticular (SR) Ca2 release and uptake, SR Ca2 content, and probably reduction in sarcolemmal Na /Ca2 exchange.
Mitochondrial Hsp 70-function and evolution

H molecular chaperones function in variety of critical cellular processes, including protein folding, translocation of proteins across membranes and assembly/disassembly of protein complexes. Hsp70 systems consist of a core Hsp70 protein and its co-chaperones: J-protein and nucleotide release factor NRF. These co-chaperones regulate the cycle of interaction with protein substrate via stimulating the ATPase activity of Hsp70 (J-protein) and promoting nucleotide exchange (NRF). Compartments within the eukaryotic cell often contain multiple Hsp70s, J-proteins and NRFs. The capabilities of these systems to carry out diverse cellular functions results from either specialization of an Hsp70 or by interaction of multifunctional Hsp70 with an array of specialized J-proteins. The well-studied Hsp70 systems of yeast mitochondria provide an excellent example of functional divergence and evolution of Hsp70 machineries.
Wide genetic diversity of Ralstonia solanacearum strains affecting tomato in Trinidad, West Indies

Thegeneticdiversityof Ralstoniasolanacearum causingbacterialwiltoftomatoinTrinidadwasassessedusingthehierarchical phylotypingschemeand rep-PCRDNA ﬁngerprinting. Seventy-oneisolates were collected in 2003 on infected tomato cropsin thefourmainvegetablecroppingareasofTrinidad(North,Central,South-EastandSouth). Twophylotypeswerepresent,with phylotype II being much more prevalent (66%) than phylotype I (34%). Phylotype II strains consisted mainly of sequevar 7 in Central and South-East, and sequevar 35 in North, South-East and South. This is the ﬁrst report of sequevar 7 outside southeastern USA. In contrast, no ‘brown rot’ (phylotype IIB ⁄ 1, race 3 biovar 2) or emerging strains of phylotype IIB ⁄ 4NPB were identiﬁed. Rep-PCR data were used to assess population genetic structure. No signiﬁcant clustering by geographical distance was found, suggesting regular gene ﬂow among cropping areas (via waterways, plant or soil). However, the population from Centralwassigniﬁcantlydifferentiatedfromtheothers,containingonlyphylotypeII ⁄ seq7strains,withahighdegreeofclonal-ity, suggesting a possible recent introduction from abroad. The South population was less aggressive and more genetically diverse, suggesting horizontal gene transfers within the population, even among isolates of different phylotypes.

Perspective Paper Indian Industry: A Seven-Decade Journey and the Road Ahead

Industrialisation in its true sense began in India only after her independence in 1947. It has been a long journey since then. Initially, for about four and half decades since 1947, based on the Import-substitution strategy, Indian industry functioned in a highly regulated and protected environment dominated by the public sector. However, a paradigm shift occurred in India’s industrialisation strategy in the early 1990s as a new policy regime aimed at opening up and deregulation of Indian industry was adopted to facilitate the growth of competition. While the Indian industry has been functioning according to this policy regime for the last three decades, new issues have started to emerge. The paper attempts to unravel the cause and consequence of the process of industrialisation that has unfolded in India over the last seven decades and tries to analyse the challenges confronting the Indian industry at present and suggest the policy initiatives that could tackle them.

A text‐meandered RFID tag implemented with conductive threads

We present a wearable RFID tag implemented on a fabric, comprising four alphabet texts embroidered by conductive threads. The tag is optimized to provide a conjugate match to the RFID chip impedance at the operation frequency, 910 MHz. Various tags with different stitching patterns and thread diameters are examined in simulation and a number of tags are measured using two‐port differential probe suitable for balanced tag structures. The measured results of tag impedance show good agreements to the simulation results with slight errors caused by imperfection in probe calibration. © 2016 Wiley Periodicals, Inc.
