Authors: Oktay Burcu , Baştürk Emre , Kahraman Memet Vezir , Apohan Nilhan Kayaman 
Published: May 2019

AbstractPhase change material (PCM) is an effective energy storage application, which has a relatively low cost. In this study, bio‐based PCMs were prepared by using two techniques: encapsulation and UV‐curing. Encapsulated–PCM was synthesized by suspension polymerization with stearyl methacrylate (SMA) and hydroxyethyl methacrylate (HEMA). In encapsulation process, the microcapsules were prepared from poly(stearyl methacrylate‐co‐hydroxyethyl methacrylate) shell and coconut oil (CO) core. UV‐cured form stable PCM was also prepared by radical addition polymerization of stearyl methacrylate, hydroxyethyl methacrylate and coconut oil. In UV‐curing process as in the second process, coconut oil was trapped within the polymeric network without covalent bonding. Thermal storage feature of encapsulated‐PCM and UV‐cured form stable PCM was investigated. The melting enthalpy of encapsulated‐PCM is 119 J/g, which is higher than both the melting enthalpy of pure coconut oil (106 J/g) and UV‐cured form stable PCM (47 J/g). Moreover, thermal degradation results of PCMs show that the maximum thermal decomposition temperature of encapsulated‐PCM increased compared with UV‐cured from stable PCM.

Published: May 2019

AbstractPerovskite thin films hold promise as a potential candidate for high efficiency solar cells. In recent years, a wealth of results has been published on CsPbI3 thin films. However, most of the literature reports that CsPbI3 perovskite films are prone to aging where black colored CsPbI3 films with cubic lattice change to yellow colored films with orthorhombic lattice upon exposure to ambient conditions. This poor stability presents itself as a major challenge in utilization of CsPbI3 for device applications. This manuscript presents an alternate route for fabricating stable CsPbI3 thin films using thermal evaporation. Experimentally, our samples were found to be stable, visually and structurally, over a period of six months. Even annealing of the samples did not induce structural changes.

AbstractA class of chiral sulfinamide monophosphine ligands Ming‐Phos were firstly employed in the asymmetric Suzuki coupling reactions. Using the in‐situ formed catalyst from PdCl2 and (R, SS)‐M07, 22 axially chiral phosphonates or phosphine oxides were successfully synthesized in 29−99% yields with up to 98% ee. This method provides a simple and efficient protocol for the synthesis of axially chiral biaryl monophosphine oxides.
Latitudinal Growth Variation in Young Tautogs: A Field, Laboratory, and Growing Degree‐Day Assessment of Potential Intrinsic Differences in Growth Responses to Temperature
Authors: Martin Daniel L. , Targett Timothy E. 
Published: May 2019

AbstractA difference in size at age of young Tautogs Tautoga onitis has been reported from two sites in the Mid‐Atlantic Bight, USA, whereby southern fish (Virginia [VA]) reach a twofold greater size than northern fish (Rhode Island [RI]) by age 1 but grow at similar size‐dependent annual rates thereafter. We investigated the basis for this difference by using a coordinated field, laboratory, and growing degree‐day (GDD) approach. Age‐0 Tautogs were sampled from three locations (Chesapeake Bay, VA; Delaware Bay, Delaware [DE]; and Narragansett Bay, RI) and showed a clinal relationship of decreasing fish size and growth rate with increasing latitude. Otolith‐based estimates of larval stage duration and growth rate showed no significant clinal relationship. Young Tautogs from these locations were reared in common‐garden experiments (at 5, 15, and 25°C) to determine whether there were intrinsic postsettlement growth differences related to temperature. None of the location‐specific groups of age‐0 Tautogs exhibited growth that was consistently faster than that of Tautogs from the other locations over all temperatures examined. These data and the results of a GDD assessment between VA and RI indicate that latitudinal differences in temperature regime and growing season length are the major factors determining latitudinal growth differences in age‐0 fish. However, age‐1 RI fish of equivalent size grew significantly faster than age‐0 RI and DE fish and similar to age‐0 VA fish at 15°C and grew 40% faster than all age‐0 fish at 25°C, suggesting countergradient growth variation in age‐1 and older northern Tautogs. Size‐selective overwinter mortality of age‐0 northern fish—whereby smaller individuals are most susceptible to low temperature—is proposed as the likely underlying mechanism leading to faster growth of older northern fish at temperature. Such a mechanism would at least partially compensate for the lower temperature and shorter growing season at higher latitudes.
Drug screening in Drosophila; why, when, and when not?
Authors: Su Tin Tin 
Published: May 2019

AbstractThe best global seller among oncology drugs in 2018 is lenalidomide, an analog of thalidomide. It took 53 years and a circuitous route from the discovery of thalidomide to approval of an analog for use in treatment of cancer. We understand now a lot more about the genetic and molecular basis of diseases than we did in 1953 when thalidomide was discovered. We have also no shortage of chemical libraries with hundreds of thousands of compounds, both synthetic and natural. What we need are better ways to search among these rich resources for compounds with the potential to do what we want them to do. This review summarizes examples from the literature that make Drosophila melanogaster a good model to screen for drugs, and discusses knowledge gaps and technical challenges that make Drosophila models not as widely used as they could or should be.This article is categorized under:

Infantile-Onset Multisystem Neurologic, Endocrine, and Pancreatic Disease: Case and Review
Authors: Le Christine , Prasad Asuri N. , Rupar C. Anthony , Debicki Derek , Andrade Andrea , Prasad Chitra 
Published: May 2019

ABSTRACT:We report three brothers born to consanguineous parents of Syrian descent, with a homozygous novel c.324G&gt;A (p.W108*) mutation in PTRH2 that encodes peptidyl-tRNA hydrolase 2, causing infantile-onset multisystem neurologic, endocrine, and pancreatic disease (IMNEPD). We describe the core clinical features of postnatal microcephaly, motor and language delay with regression, ataxia, and hearing loss. Additional features include epileptic seizures, pancreatic insufficiency, and peripheral neuropathy. Clinical phenotyping enabled a targeted approach to the investigation and identification of a novel homozygous nonsense mutation in PTRH2, c.324G&gt;A (p.W108*). We compare our patients with those recently described and review the current literature for IMNEPD.
Renal Failure Patients in Disasters
Authors: Lempert Kenneth D. , Kopp Jeffrey B. 
Published: May 2019

ABSTRACTDisasters occur regularly, and frequently large numbers of patients treated with maintenance dialysis or with the recent onset of acute kidney injury are put at risk owing to the lack of access to dialysis care precipitating also a kidney failure disaster. The absence of necessary dialysis treatments can result in excessive emergency department visits, hospitalizations, morbidity, or an early death. Those with kidney failure are often evaluated in disaster medical locations or hospitals without nephrologists in attendance. Here we offer guidance for medical personnel evaluating such patients so that dialysis-dependent individuals can be properly assessed and managed with the need for urgent dialysis recognized. A disaster dialysis triage system is proposed. (Disaster Med Public Health Preparedness.2019;13:782–790)
‘For how Long can your Pīharwāle Intervene?’: Accessing natal kin support in rural North India
Authors: CHAUDHRY SHRUTI 
Published: May 2019

AbstractBased on ethnographic fieldwork in rural Uttar Pradesh, this article contributes to debates on married women's relations with their natal kin. It compares women in ‘regional’ marriages (which conform to caste and community norms with a relatively small marriage distance) with women in ‘cross-regional’ marriages (those that cross caste, linguistic, and state boundaries, and entail long-distance migration). A focus on cross-regional marriage demonstrates how geographic distance cuts women off from vital structures of support. At the same time, even for regional brides, natal kin support is complicated and relative proximity does not guarantee support. Factors such as caste, class, poverty, the gender of children, notions of honour and shame, and stage in the life-course work together in complex ways to determine the duration and kind of support available. By focusing on marital violence, marital breakdown, and widowhood, the article demonstrates both the presence and the limits of natal kin support. The opportunities to draw on natal kin support vary for women, but its significance must not be understated as it alone provides women with the possibility of leaving their marriages, even if only temporarily. The article focuses on one form of women's agency, one that is constrained and highly dependent on relationships with others (mainly male kin). In such a context of economic and social dependency, natal kin support is an important—and perhaps the only—resource available in situations of marital crisis, and its absence leaves women in a particularly vulnerable position.

AbstractTrypanosoma cruziis the causative agent of Chagas disease, a vector-borne disease. The parasite molecules involved in vector interaction have been little investigated. Metallopeptidases and gp63 molecules have been implicated in parasite adhesion of several trypanosomatids to the insect midgut. Although gp63 homologues are highly expanded in theT. cruzigenome, and are implicated in parasite–mammalian host interaction, its role in the insect vector has never been explored. Here, we showed that divalent metal chelators or anti-Tcgp63-I antibodies impairedT. cruziadhesion toRhodnius prolixusmidgut. Parasites isolated after insect colonization presented a drastic enhancement in the expression of Tcgp63-I. These data highlight, for the first time, that Tcgp63-I and Zn-dependent enzymes contribute to the interaction ofT. cruziwith the insect vector.
Tilestones into Whetstones in Seven Steps: the Brownstones, Pennant Sandstone and Stonesfield Slate at Silchester (Calleva Atrebatum), North Hampshire
Authors: Allen J.R.L. 
Published: May 2019

ABSTRACTRoughly two-thirds of an assemblage of 156 whetstones from three collections representing two late Roman sites at Silchester can be assigned geologically to the Brownstones (Devonian), Pennant sandstone (Carboniferous) or Stonesfield Slate (Jurassic), imported from the west and north into the town as roof-tiles. The latter were put to further, secondary use as whetstones, some small and portable but others large and laid flat and kept stationary. The whetstones are polished through use, typically on both faces, and a high proportion carry grooves. On some the grooves are short and fine and could represent the sharpening of such items as pins, needles, meat skewers, styli and engraving tools. These grooves are typically found on whetstones from Insula IX, where artisanal and, at best, ‘light-industrial’ activities are recorded. At the forum-basilica, by contrast, the whetstones are more substantial and typically show large grooves of two kinds that point to the shaping and finishing in considerable numbers of iron objects such as knives, cleavers, swords and even possibly ladles. The industrial activity at this site had a distinctly ‘heavier’ quality. The biography of these whetstones — objects seemingly simple and unpretentious — was complex, wherever they were found.

AbstractObjective:To examine a comprehensive approach for preventing percutaneous injuries associated with phlebotomy procedures.Design and Setting:From 1993 through 1995, personnel at 10 university-affiliated hospitals enhanced surveillance and assessed underreporting of percutaneous injuries; selected, implemented, and evaluated the efficacy of phlebotomy devices with safety features (ie, engineered sharps injury prevention devices [ESIPDs]); and assessed healthcare worker satisfaction with ESIPDs. Investigators also evaluated the preventability of a subset of percutaneous injuries and conducted an audit of sharps disposal containers to quantify activation rates for devices with safety features.Results:The three selected phlebotomy devices with safety features reduced percutaneous injury rates compared with conventional devices. Activation rates varied according to ease of use, healthcare worker preference for ESIPDs, perceived “patient adverse events,” and device-specific training.Conclusions:Device-specific features and healthcare worker training and involvement in the selection of ESIPDs affect the activation rates for ESIPDs and therefore their efficacy. The implementation of ESIPDs is a useful measure in a comprehensive program to reduce percutaneous injuries associated with phlebotomy procedures.
Exogenous application of methyl jasmonate to Ficus hahliana attracts predators of insects along an altitudinal gradient in Papua New Guinea
Authors: Mrazova Anna , Sam Katerina 
Published: May 2019

AbstractIn many plants, the defence systems against herbivores are induced, and may be involved in recruiting the natural enemies of herbivores. We used methyl jasmonate, a well-known inducer of plant defence responses, to manipulate the chemistry of Ficus hahliana along a tropical altitudinal gradient in order to test its ability to attract the enemies of herbivores. We examined whether chemical signals from MeJA-treated trees (simulating leaf damage by herbivores) attracted insect enemies in the complex settings of a tropical forest; and how this ability changes with altitude, where the communities of predators differ naturally. We conducted the research at four study sites (200, 700, 1700 and 2700 m asl) of Mt Wilhelm in Papua New Guinea. Using dummy plasticine caterpillars to assess predation on herbivorous insect, we showed that, on average, inducing plant defences with jasmonic acid in this tropical forest increases predation twofold (i.e. caterpillars exposed on MeJA-sprayed trees were attacked twice as often as caterpillars exposed on control trees). The predation rate on control trees decreased with increasing altitude from 20.2% d−1 at 200 m asl to 4.7% d−1 at 2700 m asl. Predation on MeJA-treated trees peaked at 700 m (52.3% d−1) and decreased to 20.8% d−1 at 2700 m asl. Arthropod predators (i.e. ants and wasps) caused relatively more attacks in the lowlands (200–700 m asl), while birds became the dominant predators above 1700 m asl. The predation pressure from birds and arthropods corresponded with their relative abundances, but not with their species richness. Our study found a connection between chemically induced defence in plants and their attractivity to predators of herbivorous insect in the tropics.
Managing stress with experience feedback in crisis situation
Authors: Teffali Sammy , Matta Nada , Chatelet Eric 
Published: May 2019

AbstractA crisis is a complex situation, which actors have some difficulties to manage it. They are under stress to deal with problems that they cannot predict consequences. The human conditions (familial and life) and, the influence of the environment (politic, economic, media) pushes the actors to lose control of the crisis situation. The question we face in this paper is: “is it possible to predict the impact of the stress in this type of situation?” Our main hypothesis to answer is to represent experience feedback using knowledge management. To model the crisis management as systemic system emphasizing regulation loops, and the collaboration activity by showing the dimension of the communication, coordination, and cooperation. This modeling is illustrated in a terrorist attack situation in Algeria. To predict stress consequences, fuzzy set principle is adopted, based on experience feedback and situations modeling, as a generator of alternative states given a stress event.
Integrated optimization of mixed-model assembly sequence planning and line balancing using Multi-objective Discrete Particle Swarm Optimization
Authors: Ab Rashid Mohd Fadzil Faisae , Tiwari Ashutosh , Hutabarat Windo 
Published: May 2019

AbstractRecently, interest in integrated assembly sequence planning (ASP) and assembly line balancing (ALB) began to pick up because of its numerous benefits, such as the larger search space that leads to better solution quality, reduced error rate in planning, and expedited product time-to-market. However, existing research is limited to the simple assembly problem that only runs one homogenous product. This paper therefore models and optimizes the integrated mixed-model ASP and ALB using Multi-objective Discrete Particle Swarm Optimization (MODPSO) concurrently. This is a new variant of the integrated assembly problem. The integrated mixed-model ASP and ALB is modeled using task-based joint precedence graph. In order to test the performance of MODPSO to optimize the integrated mixed-model ASP and ALB, an experiment using a set of 51 test problems with different difficulty levels was conducted. Besides that, MODPSO coefficient tuning was also conducted to identify the best setting so as to optimize the problem. The results from this experiment indicated that the MODPSO algorithm presents a significant improvement in term of solution quality toward Pareto optimal and demonstrates the ability to explore the extreme solutions in the mixed-model assembly optimization search space. The originality of this research is on the new variant of integrated ASP and ALB problem. This paper is the first published research to model and optimize the integrated ASP and ALB research for mixed-model assembly problem.
The Australian Association of Special Education 2004 National Conference: Des English Memorial Lecture Behaviour – Whose Choice?
Authors: Jacob Alison 
Published: May 2019

Thank you for inviting me to deliver the Des English Memorial Lecture for the second time – it's becoming a bit of a habit!Having taken the opportunity to read several of the Des English lectures that have been published over the years, it appears that the tradition of this lecture is often to provide some commentary on changes that have occurred during the career of the person delivering the address, in relation to the field of special education. There is more than a little reminiscing and nostalgia in Des English lectures and a great many references to ‘journeys’ by various Des English presenters suggesting a sense of progress or at least progression over time.
Recommendations for the use of palivizumab as prophylaxis against respiratory syncytial virus in infants with congenital cardiac disease

New data are emerging on the use of palivizumab as prophylaxis against infection with the respiratory syncytial virus in infants with congenital cardiac disease. Following a 4-year multicentre randomised trial, it was shown that prophylactic injections with palivizumab were effective and safe for such children. Prophylaxis consists of 5, monthly, intramuscular injections of palivizumab, at a dose of 15 mg/kg, given during the season for infection with the respiratory syncytial virus. Timing is at the discretion of the physician, depending on the onset of the season locally. It is suggested that, in the United Kingdom, this should be commenced in mid-September. To help clinicians to identify appropriate candidates for palivizumab, a working group of the British Paediatric Cardiac Association has developed recommendations.Infants, namely those under 1 year old, with congenital cardiac disease likely to benefit from prophylaxis include those with haemodynamically significant lesions, particularly increased pulmonary blood flow with or without cyanosis; pulmonary venous congestion, pulmonary hypertension or long-term pulmonary complications, residual haemodynamic abnormalities following medical or surgical intervention (patients who have undergone cardiopulmonary bypass should receive an injection as soon as they are medically stable), cardiomyopathy requiring treatment, and congenital cardiac disease likely to need hospital admission for medical or surgical intervention during the season of infection with the virus. Prophylaxis with palivizumab may also be indicated, at the discretion of the physician, in some children with complex cardiac disease over the age of 1 year. Children less likely to benefit from prophylaxis are those with haemodynamically insignificant disease, or those with lesions adequately corrected by medical or surgical intervention.
Advanced atrioventricular conduction block in acute rheumatic fever

Published: May 2019

We carried out a retrospective case control analysis to evaluate the outcome, and the need for treatment, of problems with atrioventricular conduction occurring during an acute attack of rheumatic fever, assessing the occurrence of second and third atrioventricular block versus first degree block.We reviewed and analysed the clinical, electrocardiographic and echocardiographic records of all children diagnosed in a single institute as having acute rheumatic fever during a period of seven consecutive years.During the period from October, 1994, through October, 2001, 65 children meeting the modified Jones criterions for acute rheumatic fever were hospitalized in the Soroka University Medical Center, Israel. First-degree atrioventricular block was identified in 72.3% of the children, and resolved with no specific treatment other than non-steroidal anti-inflammatory medications. Second-degree atrioventricular block of Mobitz type I, was observed in one child (1.5%), which progressed from first-degree block, and subsequently resolved. Complete atrioventricuar block was found in 3 children (4.6%), one progressing from Mobitz type I second-degree block, and two being seen as the first presentation. Of the three children with complete atrioventricular block, one patient was not treated, the second was treated with aspirin, and the final one with combined aspirin and steroids. The disturbances of conduction resolved in all three.We conclude that advanced atrioventricular block is rare during acute rheumatic fever. If occurring, block appears to be temporary, and resolves with conventional anti-inflammatory treatment. Specific treatment, such as insertion of a temporary pacemaker, should be considered only when syncope or clinical symptoms persist.
