Electronic Detection of Oxygen Adsorption and Size‐Specific Doping of Few‐Atom Gold Clusters on Graphene

Graphene's sensitivity to adsorbed particles has attracted widespread attention because of its potential sensor applications. Size‐selected few‐atom clusters are promising candidates as adparticles to graphene. Due to their small size, physicochemical properties are dominated by quantum size effects. In particular, few‐atom gold clusters demonstrate a significant catalytic activity in various oxidation reactions. In this joint experimental and computational work, size‐selected gold clusters with 3 and 6 atoms adsorbed on graphene field‐effect transistors and their interaction with molecular oxygen are investigated. While oxygen adsorbs at both cluster sizes, there is a pronounced cluster size dependence in the corresponding doping, as demonstrated via first‐principle calculations and electronic transport measurements. Furthermore, the doping of gold cluster decorated graphene changes sign from n‐ to p‐doping upon oxygen adsorption, directly evidencing electron transfer to the oxygen molecules and hence their activation. These observations pinpoint graphene as a valuable platform to investigate and exploit size‐dependent cluster properties.
Attitudes Toward Information Technology Among Operating Theatre Nurses in Sri Lanka

Incorporating the use of information and communication technologies (ICT) into everyday professional practice requires nurses to overcome resistance to change and to become willing users and creative operators of IT. Managing the change process effectively while implementing eHealth (e.g., Hospital Information Systems) within the operating theatre environment can facilitate the efficient delivery of quality patient care. Aim: To describe the uses of and attitudes toward current IT by operating theatre nurses at The National Hospital of Sri Lanka (NHSL). Methods: The research used a descriptive design and survey method. The study population was theatre nurses working in 16 theatres. A convenience sample of 112 nurses selected from the 16 theatres was used. Nurses with a service period over 20 years were excluded. Data were gathered with a self-administered questionnaire. Results: The response rate was 97 of 112 (87%). The study found that nurses were highly confident in using computers, touch screens, the Internet and email. Almost 80% of theatre nurses used computer technology for their work and personal matters. However only 60% of the nurses had personal email addresses. Furthermore, 79% of nurses believed that computers would reduce paper work. Conclusion: Most operating theatre nurses possess a positive attitude toward advances that use IT applications. This may be due to the growing presence and accessibility of IT in their work environment, which has added value in their day to day practice in the hospital. To facilitate ongoing growth in use of IT in Sri Lanka, continuing education opportunities for operating theatre and other nurses should be pursued.
Aboriginal English and Responsive Pedagogy in Australian Education

Aboriginal English1, the language many Aboriginal and Torres Strait Islander students bring to the classroom, represents the introduction of significant change into the English language. It is the argument of this paper that the linguistic, social and cultural facts associated with the distinctiveness of Aboriginal English need to be taken into account in the English language education of both Aboriginal/Torres Strait Islander and non-Indigenous students in Australia. The paper illustrates seven significant changes of expression which Aboriginal English has made possible in English. It then proposes a “responsive pedagogy” to represent a realistic and respectful pedagogicalresponse to the linguistic, social and cultural change which underlies Aboriginal English, drawing on current literature on second language and dialect acquisition and making frequent reference to materials whichhave been developed to support such pedagogy. It is implied that only with a pedagogy responding to Aboriginal English as it is, and to its speakers, will a viable English medium education for Aboriginal and Torres Strait Islander people be enabled. 1Aboriginal English” is the term used to denote “a range of varieties of English spoken by many Aboriginal and Torres Strait Islander people and some others in close contact with them which differ in systematic ways from Standard Australian English at all levels of linguistic structure and which are used for distinctive speech acts, speech events and genres” (Malcolm 1995, p 19).
AN ERGONOMIC CLASSROOM DESIGN APPLICATION AT A UNIVERSITY IN TURKEY

Purpose: Ergonomics is a branch of science that uses scientific methods to improve the workplaces and environments to maximize the comfort and safety of humans. In this study, we suggest new classroom furniture dimensions defining the problems about environmental factors in the classrooms such as noise, light, air conditioning, or temperature by considering the real data obtained from a university. Methodology: A questionnaire is prepared to determine the most complained problems by the students about the classroom furniture and environment. A total of 219 students participate in the questionnaire at a university in Ankara, Turkey. The dissatisfaction scores are evaluated for each question to define the most complained problems. Findings: The results show that most of the students are not satisfied with the use of tablet-armed chairs due to different reasons. To solve the problems, the anthropometric measurements of the students are evaluated. Based on these measurements, new furniture dimensions are suggested and compared with the existing ones. Originality: The ergonomic classroom design in this study is an original work that is designed according to the data obtained from the university in concern. It is aimed that the implemented methodology and the comprehensive literature review for the ergonomic classroom design in this study can be a source of inspiration for the educational institutions.
Learning from Noisy Complementary Labels with Robust Loss Functions

SUMMARY It has been demonstrated that large-scale labeled datasets facilitate the success of machine learning. However, collecting labeled data is often very costly and error-prone in practice. To cope with this problem, previous studies have considered the use of a complementary label, which speciﬁes a class that an instance does not belong to and can be collected more easily than ordinary labels. However, complementary labels could also be error-prone and thus mitigating the inﬂuence of label noise is an important challenge to make complementary-label learning more useful in practice. In this paper, we derive conditions for the loss function such that the learning algorithm is not a ﬀ ected by noise in complementary labels. Experiments on benchmark datasets with noisy complementary labels demonstrate that the loss functions that satisfy our conditions signiﬁcantly improve the classiﬁcation performance.
Kapabilitas Dinamik dan Keunggulan Bersaing: Dinamisme Lingkungan Moderator ataukah Driver?

The aim of this study is to investigate the role of environmental dynamism in relation to dynamic capabilities and competitive advantage. This study uses a quantitative approach and type of explanatory research. The survey was conducted at 130 MSMEs in Malang Raya. Hypothesis testing using SEM-PLS. The findings of the study prove that environmental dynamism is a driver for dynamic capability, while providing evidence that environmental dynamism acts as a negative moderator for achieving competitive advantage. Another finding is that dynamic capabilities have a major effect on competitive advantage while simultaneously acting as fully mediating environmental dynamism with competitive advantage. The implication is important for MSMEs to develop dynamic capabilities in order to deal with environmental dynamism so that MSMEs can increase competitive advantage because if they do not develop dynamic capabilities, environmental dynamism will reduce MSME's competitive advantage.

Deformation mechanisms in nanotwinned γ-TiAl by molecular dynamics simulation

ABSTRACT In this work, the plastic deformation mechanisms and fracture toughness of nanotwinned γ-TiAl with different twin boundary (TB) spacing are investigated by using molecular dynamics simulation. The simulation results reveal that there are pronounced shifts in the mechanical behaviour of nanotwinned γ-TiAl when the TB spacing is 3.50, 4.20 and 4.90 nm. In addition, the variation of the dislocation density with strain at these three TB spacing illustrates that a smaller TB spacing induces a higher dislocation density. Different TB spacing has an influence on the dislocation behaviour. The dislocation pile-up, dislocation–dislocation, dislocation–twin and twin–twin reactions, hierarchical twins including their generation and density, step formation, dislocation emission from steps and TB migration are the main plastic deformation mechanisms. The results also show that TB migration, twinning formation and interaction of crack and TB dominate the deformation mechanism of nanotwinned γ-TiAl with crack. The generation of hierarchical twins, lower distance between crack surface plane and twin plane, dislocation–twin, twin–twin interaction and crack deflection increase the fracture toughness of nanotwinned γ-TiAl.
Adaptive Sliding-Mode Control of a Novel Buck-Boost Converter Based on Zeta Converter

The adaptive sliding-mode control of a high efficiency non-isolated buck-boost converter based on Zeta converter is presented. The converter has a dc gain higher than that of the Zeta converter and is a sixth-order system. The controller uses the inductor current error and a proportional term to generate the control action. The reference inductor current is first calculated using the estimated load conductance obtained from an adaptation algorithm. The proposed and existing sliding-mode controllers are closely related under certain conditions. The stability analysis of the closed-loop system is performed and sheds light on the controller’s effectiveness. Experimental results are given to validate the theory.

Effect of planting dates on stem borer incidence and its natural enemies in relation to weather variables in rice ecosystem

The field experiment was conducted in the rice field of Regional Agricultural Research Station, Assam Agricultural University, Titabar, Assam in randomized block design sowing the seeds in three dates at an interval of twenty days between each sowing, viz., early (15 May), normal (5 June) and late (25 June) separately. Early sown was the least damaged crop ( 9.6% dead heart (DH) and 10.3% white ear head (WEH) as compared to normal (15.5 % DH and 16.7% WEH) and late (24.6% DH and 25.3% WEH) with a yield of 5.3t/ha in early, 4.5 t/ha in normal and 2.4t/ha in late sown crops. Spider population was significantly higher in early than that of normal and late planting, whereas the population of coccinellid beetles and the egg parasitoid, Trichogramma japonicum were non-significantly higher in early than that of normal sown crop, but the population of these natural enemies were significantly lower in late sown rice. The stem borer infestation was significantly higher in late sown crop with increased maximum temperature, morning humidity having a significant positive effect in all the dates of planting. There were a nonsignificant positive effect on population with minimum temperature (r = 0.34 for DH and r = 0.22 for WEH) and average rainfall (r = 0.20 for DH and r = 0.07 for WEH) at early sown. Maximum temperature and morning relative humidity had a significant positive effect on borer infestation as dead heart and white ear head in connection with a significant positive effect of spider population in three dates of planting. The variation in the planting times work as a means of cultural control by creating asynchrony between crop and insect pests’ phenology along with crop-weather-pest interaction help in developing forewarning system to warn the farmers in advance to avoid manageable yield loss by stem borer incidences.
Deployment of parabolic trough concentrated solar power plants in North Africa – a case study for Libya

ABSTRACT The study addresses the potential of using concentrated solar power plants (CSPs) as a sustainable alternative of clean energy generation in the Mediterranean region and, in particular, in its North Africa shore. This location presents attractive conditions for the installation of CSPs, in particular high solar irradiation, good manpower concentration, and proximity and availability of water resources for condenser cooling. Energetic, exergetic, and economic analyses were conducted taking into consideration a particular type of CSPs - the parabolic trough concentrated solar power plant, which incorporates the most proven technology and it is already used in Southern Europe (Spain). In addition, the study considered the impact of project financing and incentives on the cost of energy. The combination of higher values for performance and potentially lower levelized cost of electricity (LCE) for the North Africa Mediterranean Rim than the South of Spain region can yield a very favorable return for the invested capital. Tripoli compared to Almeria presented superior performance and potentially lower LCE values ($0.18/kWh versus $0.22/kWh). This is significant, even when it is taken into consideration the fact that the plant in Tripoli, despite a relatively modest capacity factor of 34%, has a large gross power output of 173,886 MWhe. In addition, the implementation at the Tripoli location of a plant similar to the Anadsol plant has a slight advantage (2–3%) in terms of overall efficiency.
Understanding the fitness, preference and performance of specialist herbivores of the Southern African biotype of Chromolaena Odorata (Asteraceae), and impacts on phytochemistry and growth rate of the plant.

The invasiveness and negative impacts of the alien shrub, Chromolaena odorata (L.) (Asteraceae) in South Africa resulted in the initiation of a biological control programme against the weed in the late 1980s. After the release of seven biocontrol agents, only two have successfully established to date viz. a leaf mining fly, Calycomyza eupatorivora Spencer (Diptera: Agromyzidae) and a moth with defoliating larvae, Pareuchaetes insulata Walker (Lepidoptera: Erebidae: Arctiinae). Surveys conducted suggested that C. odorata densities seem to be low in KwaZulu-Natal (KZN) province where P. insulata is present whilst its infestation is increasing in other places such as Limpopo province where the moth is absent. This study aimed to examine the life history traits, preference and performance of two biocontrol agents, viz. Dichrorampha odorata (Lepidoptera: Tortricidae) and Polymorphomyia basilica (Diptera: Tephritidae). A further objective of the study was to measure the effects of one of the established agents, P. insulata, on the competitive ability and defence mechanism of C. odorata by indirectly testing the predictions of the Evolution of Increased Competitive Ability (EICA). Studies of life history traits of D. odorata in the laboratory indicated that the moth possesses good biological control attributes such as short-lived adults with high mating success, fecundity and egg hatchability. Of the 34 asteraceous plants subjected to larval no-choice tests, only C. odorata could sustain complete development of D. odorata to adulthood, although there was slight initial boring on 14 test species (plus C. odorata). Adult no-choice tests using seven test-plant species that were damaged in larval no-choice tests were consistent with the earlier trials, with larval damage, pupae and adults of D. odorata recorded from only C. odorata. This demonstrated that only C. odorata is a suitable host for D. odorata in South Africa and permission for the release of this first shoot-tip attacking agent was granted for biocontrol of C. odorata in South Africa. To predict the efficacy of D. odorata as a biological control of C. odorata, a 9-month laboratory study was carried out. Plant growth metrics were compared across three treatments i.e. 0, 50 and 100% where newly hatched D. odorata larvae were inoculated

FORAGE YIELD, QUALITY CHARACTERS AND GENETIC VARIABILITY OF SOME PROMISING EGYPTIAN CLOVER POPULATIONS

The present study was conducted to evaluate eight berseem populations (selected for high forage yield) with five check cultivars and to estimate the relationships between yield, some growth parameters, quality characters, genetic variance, phenotypic variance, heritability, genotypic and phenotypic coefficient of variability in the experimental research station at Nubaria region, Al-Behira government across the two growing seasons 2015/2016 and 2016/2017. The results could be summarized from the combined analysis of the two seasons which indicated that the cultivar Helaly recorded the highest fresh and dry yield (71.065, 9.783 kg/plot) followed by the promising Pop.4 (70.579, 9.699 kg/plot) and Pop.6 (69.388, 9.683 kg/plot), respectively with insignificant differences. Helaly, Gemmiza- 1 and Pop.6 recorded the highest values of dry leaf/stem ratio with insignificant differences. The highest fresh leaf/stem ratio was obtained from Helaly, Pop.4 and Pop.6. While Pop.1 and Giza-6 recorded the lowest values of fresh and dry leaf/stem ratio. However, mean percentage of crude protein (CP %) and digestible crude protein (DCP %) were lower in Serw- 1 and Pop.1, while, Pop.46 and Gemmiza-1 recorded the highest values of CP% and DCP%. Helaly, Pop.46 and Gemmiza-1 gave the highest values of crude fiber (CF%) and ash%. Heritability was high for all traits studied. Fresh leaf/stem ratio showed the highest heritability (97.50%) followed by dry leaf/stem ratio (96.38%). A positive correlation was obtained between ash% with dry leaf/stem ratio and dry leaf/stem ratio (r = 0.87** and r = 0.86**), and between crude fiber with dry leaf/stem ratio and dry leaf/stem ratio (r = 0.90** and r = 0.84**). Besides, there was highly significant correlation between crude fiber% and ash% (r =-0.94**). The results reflected that Pop.4 and Pop.6 did not differ significantly from the commercial cultivar Helaly, and therefore it is recommended to multiply and use them in the breeding program to improve the productivity of Egyptian clover.
India’s Food Supply Chain during the Pandemic

We document the impact of India’s COVID-19 lockdown on the food supply chain. Food arrivals in wholesale markets dropped by 69% in the three weeks following the lockdown and wholesale prices rose by 8%. Six weeks after the lockdown began, volumes and prices had fully recovered. The initial food supply shock was highly correlated with early incidence of COVID-19. We provide evidence that this correlation is due more to state-level lockdown policy variation than local responses of those in the food supply chain. Finally, during the recovery phase, the correlation between the food supply disruption and COVID-19 exposure disappeared, suggesting uniform recovery.
