Authors: Navamani Preethi Elizabeth , Swaminathan Anand 
Published: June 2019

AbstractIn this article, a circular substrate integrated waveguide (CSIW) antenna is proposed. Conventional log‐periodic antenna offers unidirectional and bidirectional radiation patterns that are used in two‐way communications provide moderate gain. The proposed antenna has the advantages of high gain, compact size, low loss, easy to integrate the high frequency components, and it also operates at L band and S band frequencies. To improve the gain and radiation characteristics, circular SIW is introduced and integrated with log‐periodic antenna. The comparison between simulated and measured results shows that the proposed antenna used for wireless communications both in L (1‐2 GHz) and in S (2‐4 GHz) frequency bands. It provides the bandwidth of 9.1%, 10%, 21.6%, and 11.03% and also the realized gain of 6.62 dB, 15.8 dB, 3.9 dB, and 8.3 dB is obtained in 1.2 GHz, 1.6 GHz, 2.4 GHz, and 2.9 GHz, respectively.

AbstractCompounds containing [B10H10]2− cluster are promising candidates that can be used as high energetic fuels and burning rate modifiers for propellants. The ignition and combustion behaviors of [N(C2H5)4]2B10H10 were investigated using a laser ignition system in air. Results show that [N(C2H5)4]2B10H10 (∼2.0 mm) is ignited with a delay of around 350 ms and threshold ignition energy of 0.7 J at laser ignition power density of 1.14×107 W/m2. Furthermore, the combustion of [N(C2H5)4]2B10H10 in air is found to undergo three stages of decomposition, incomplete combustion of the volatile pyrolytic products, and ejection and combustion of the molten dehydrogenated framework, giving massive smoke and a characteristic pyrotechnic flame.

Published: June 2019

AbstractObjectiveDoes group physiotherapy methods produce different results when compared with individual physiotherapy in persons with surgically repaired rotator cuff tears? No studies to date have examined the feasibility or effectiveness of such therapy formats. Given the prevalence of rotator cuff tears, a study examining group format therapy is warranted and can produce evidence to transform care for rotator cuff tear rehabilitation.MethodsWe analyzed the electronic medical records of persons that underwent rotator cuff repair surgery followed by the prescribedpost‐surgical physiotherapy at Southlake Regional Health Centre. Both groups were provided standard physiotherapy intervention protocol for post‐operative rotator cuff tear. Active range of motion (AROM), quick disabilities of the arm, shoulder and hand (Q‐DASH) measures, and efficiency measures were examined for differences between groups.ResultsNo significant differences between AROM (abduction p = .92, lateral rotation p = .64, and flexion p = 1.00) and Q‐DASH (p = .62) measures between groups were observed at discharge. Overall, group therapy participants required a greater number of visits (p = .000); however, when separated by age groups, only the 60‐ to 69‐year‐old participants significantly differed in number of visits between groups (p = .000), whereas no difference was observed in the 50‐ to 59‐year‐old participants (p = .14).ConclusionGroup format physiotherapy may be equally effective as individual formats in improving AROM and functional outcomes of participants with surgically repaired rotator cuff tears. Further research is needed to determine the optimal age range for group therapy interventions in this population.

Plant derivatives, such as anthocyanin‐rich phytochemicals, have been reported to elicit a positive effect on lipid profile. Therefore, the aim of this study was to systematically review and meta‐analyze the effects of Aronia consumption on lipid profiles, blood pressure, and biomarkers of inflammation in randomized controlled trials. A systematic search was performed in PubMed/MEDLINE, Cochrane, and SCOPUS up to December 2018. Seven studies were identified and analyzed in this meta‐analysis. Our study found a significant increase in high‐density lipoprotein (HDL; weighted mean difference [WMD]: 1.48 mg/dl, 95% confidence interval, CI, [1.29, 1.68]) and diastolic blood pressure (WMD: 2.55 mmHg, 95% CI [0.63, 4.47]) following Aronia consumption. There was no significant effect on systolic blood pressure and C‐reactive protein, tumor necrosis factor, and interleukin‐1. Furthermore, subgroup analysis showed that cholesterol (WMD: −7.18, 95% CI [−13.90, −0.46]) and low‐density lipoprotein (LDL; WMD: −5.84, 95% CI [−6.91, −4.77]) decreased more significantly in interventions less than 10 weeks in duration. Dose–response analysis demonstrated a significant reduction in triglyceride levels when dose of Aronia was increased to 300 mg/day. In conclusion, the results demonstrated a significant increase in HDL and reduction in total cholesterol and LDL among patients supplementing with Aronia.

Published: June 2019

AbstractWe have described the development of commercially scalable synthetic process for Asenapine, an antipsychotic drug. This involved the isomerization of cis‐lactam compound 5 to required trans‐lactam compound 6 and followed by isolation without chromatographic technique. The isolation process was executed up to 10 kg batch scale and achieved with good yield and high purity of trans‐lactam compound 6. We have also developed a crystallization process to obtain the stable and pure microcrystalline monoclinic form of asenapine maleate even after micronization with desirable particle size, which was previously unpredictable from the reported crystallization process.
Ultrasound Assisted Solvent/Metal Free Synthesis of 3‐Sulfenylindoles Employing TBATB‐Grafted MCM‐48 as a suitable Heterogeneous Catalyst.
Authors: Hazarika Sukanya , Barman Pranjit 
Published: June 2019

AbstractA one pot synthesis of 3‐sulfenylindoles in a solvent and metal free condition is reported here. The ultrasonic protocol markedly accelerates the reaction between substituted indoles and disulfides providing desired products in good to excellent yield. The ultrasonication produces local heating effect which is comparatively more advantageous than conventional heating. The method is catalyzed by TBATB impregnated MCM‐48 which is as a selective and efficient heterogeneous catalyst, also a source of molecular bromine which in presence of DMSO leads to C−S coupling. The salient feature of this protocol is easy recovery and reusability of the catalyst up to minimum five consecutive cycles. The easy and clean operation, short reaction time and high yield of desired outcomes make this method a practically applicable one.

Published: June 2019

AbstractIn this research work, we report a new Mo(VI) Schiff base complex based on 1,3‐bis(4‐bromo‐2‐carboxyaldehyde phenoxy)propane, which was immobilized covalently on MnFe2O4 magnetic nanoparticles. The efficiency of the novel catalyst was investigated for the oxidation of olefins and organic sulfides. Under optimized conditions, the nanoparticle catalyst allowed selective epoxidation of cis‐cyclooctene, cyclohexene, and cis‐cyclodecane with 99% conversion in 10 min under solvent‐free condition with tert‐butyl hydroperoxide as oxidant. The catalyst also showed excellent ability for the oxidation of thioanisole, dimethyl sulfide and benzyl phenyl sulfide with a 99% conversion in 5 min and solvent‐less condition with H2O2 (30%) as oxidant. The recyclability of catalyst was also investigated in the oxidation of cyclooctene and methyl phenyl sulfide at least for 5 times.

Published: June 2019

AbstractVanadium oxide (VOx) decorated with gold‐nanoparticles via self‐assembled monolayer approach is herein reported to be an efficient electrocatalyst for both oxygen and hydrogen evolution reactions (OER and HER) in alkali medium. The voids created in the nanoflute of gold‐vanadate were believed to be responsible for high mass transfer allowing the material to be highly applicable as a catalyst for water splitting and nitro‐arene reduction. The nanoflute exhibited high current density with low onset potential value in both OER and HER. The overpotential value at 10 mAcm−2 was observed to be 310 mV with onset potential of 1.43 V in case of OER while the overpotential value for HER was measured to be 282 mV. The nanocatalyst was found to be stable upto 10 h with minimal increment in the overpotential value. The Tafel plot value of 127 mVdec−1 in OER and 131 mVdec−1 in HER also signified for the high efficacy of the catalyst towards splitting of water molecules under high basic condition. The same material was also used as catalyst for reduction of various nitro‐arenes in isopropanol with 0.25 M KOH. The liberation of hydrogen via the oxidation of isopropanol was supposed to be responsible for reduction of nitro‐arenes. The ability of the catalyst to oxidize isopropanol was substantiated from electrochemical studies.

Sensorium®: The Splash of Sensory Trademarks
Authors: Elliott Charlene 
Published: June 2019

AbstractSensory trademarks present a compelling case in which to explore the senses as “containers of possibility,” and this article explores the emergence and logic of sensory trademarks from a legal and marketers’ perspective. Using sensory trademark cases from the United States, I suggest that the current socio-legal environment opens a conversation about what I would call sensory capitalism—the monetization of the senses rather than the propertization of the senses—that requires intellectual property law to properly function. I argue that the sensory model espoused by the trademarking of the senses is one of the mass sensorium, whereby the “audience” universally recognizes marks as designating a particular source or origin of goods. The mass sensorium offers something quite novel, however, because embedded in it is the (corporate) promise of a lingua franca that valorizes all of the senses and generates a type of mediated affect that is shared.
The Functions of Law and their Challenges: The Differentiated Functionality of International Law
Authors: Burchardt Dana 
Published: June 2019

AbstractThis Article illustrates the functional and conceptual variances of law in different contexts. Whereas legal actors on the international level might normatively aim for law to have a similar effect to that of domestic law, the way in which international and supranational law can fulfill these potential functions is different. Accordingly, this Article argues that an awareness of the particularities and challenges that the potential functions of law encounter in the international and supranational context is needed. Moreover, it suggests an analytical lens to conceptually frame and locate current developments, offering a broader perspective on—or even an element of explication for—the apparent crisis that law is currently facing on the international and supranational scale. After describing the potential functions of law on an abstract scale and grouping them into analytical categories, the Article uses these categories as a lens in order to assess in which way international law can fulfill these potential functions, where priorities regarding certain functions might differ, and where some aspects of these functions are challenged when law is made and applied in the international and supranational sphere.

Published: June 2019

AbstractIntroductionThere is evidence of increased morbidity, decreased quality of life, and premature mortality in people living with HIV (PLHIV) who smoke tobacco compared to PLHIV who do not smoke tobacco. Evidence-based screening for tobacco dependence, pharmacological treatment, and treatment monitoring and education into relapse prevention are not readily available in low- and middle-income countries (LMIC). We evaluated the effects of a brief tobacco dependence intervention in improving knowledge on the health effects of smoking and intention to quit smoking in PLHIV in Nepal, a low-income country in south Asia.MethodsUsing a quasi-experimental design, we assigned 59 smokers to participate in the intervention and 67 in the control group. The 1.5 h smoking cessation intervention emphasized harms of smoking, reasons for smoking and quitting, causes of relapse in previous quit attempts, and quitting strategies. We collected data at baseline and immediately post-intervention.ResultsFindings indicate that a brief smoking cessation intervention produced a significant increase in smoking-related knowledge and intention to quit among PLHIV. The positive effects of our intervention remained significant after adjusting for potential confounders.ConclusionsOur brief tobacco dependence intervention was effective in improving knowledge on the health effects of smoking and intention to quit among PLHIV. Further studies are required to evaluate the effectiveness of our intervention in increasing smoking cessation among PLHIV in LMIC.
Molecular evolution in immune genes across the avian tree of life

Published: June 2019

AbstractAll organisms encounter pathogens, and birds are especially susceptible to infection by malaria parasites and other haemosporidians. It is important to understand how immune genes, primarily innate immune genes which are the first line of host defense, have evolved across birds, a highly diverse group of tetrapods. Here, we find that innate immune genes are highly conserved across the avian tree of life and that although most show evidence of positive or diversifying selection within specific lineages or clades, the number of sites is often proportionally low in this broader context of putative constraint. Rather, evidence shows a much higher level of negative or purifying selection in these innate immune genes – rather than adaptive immune genes – which is consistent with birds' long coevolutionary history with pathogens and the need to maintain a rapid response to infection. We further explored avian responses to haemosporidians by comparing differential gene expression in wild birds (1) uninfected with haemosporidians, (2) infected withPlasmodiumand (3) infected withHaemoproteus(Parahaemoproteus). We found patterns of significant differential expression with some genes unique to infection with each genus and a few shared between ‘treatment’ groups, but none that overlapped with the genes included in the phylogenetic study.
In vitrolipolysis and lymphatic absorption ofn-3 long-chain PUFA in the rat: influence of the molecular lipid species as carrier

Published: June 2019

AbstractThe aim of this work was to study the bioavailability of fatty acids (FA), focusing onn-3 long-chain (LC) PUFA, carried by different molecular lipid species, that is, phospholipids (PL) or TAG, with three formulations based on fish oils or marine PL, providing a similarn-3 LC PUFA amount. The digestive lipolysis was first assessed using anin vitroenzymatic model. Then, intestinal absorption and enterocyte metabolism were investigatedin vivo, on male Wistar rats through lymph lipid analysis. Thein vitroresults showed that the release ofn-3 LC PUFA from lipolysis was increased by 48 % when FA were provided as PL rather than TAG. Thein vivoresults demonstrated that EPA and DHA from both TAG and PL were similarly absorbed and incorporated into lymph lipids. However, DHA was mainly distributed at thesn-1/3 positions of lymph TAG when provided as marine PL, whereas it was equally distributed at the three positions with marine TAG. On the whole, even if the molecular lipid species ofn-3 LC PUFA did not greatly modify thein vivodigestion and absorption steps, it modulated the rearrangement of DHA on the glyceride positions of the lymph TAG, which may further impact the DHA metabolic fate and tissue accretion. Consequently, the present study has provided data which may be used to formulate lipid diets rich in DHA in the context of an insufficient consumption ofn-3 PUFA in Western countries.

Published: June 2019

AbstractMany factors, including pathogens, environmental change and breeding techniques, affect honeybee immunity/resistance, so substances and natural supplements that enhance it are desired. To eliminate the impact of unknown external factors, in 2016 a cage experiment was conducted under constant laboratory conditions (35 °C, 65% relative humidity). Bees in the control group were fed with sugar dissolved in water at ratio 1:1 ad libitum with no additives, while the other group was fed with sugar syrup (1:1) supplemented with piperine (3 µg/ml) ad libitum. The piperine-treated workers lived 9 days longer compared to the control group. In the piperine-consuming group, protein concentration and the activities of antioxidative enzymes, such as superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and glutathione S-transferase (GST), were higher than in the control group. The activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were also higher in the piperine-treated group. Neutral and acidic proteases inhibitors, as well as neutral protease activities, were higher in the haemolymph of the piperine-treated workers than in untreated bees. Acidic protease activities in the haemolymph were higher in untreated workers only on days 18 and 32. Alkaline protease activities in the control bees were higher from day 10. From 10 days old, the total antioxidant capacity level was significantly higher in the haemolymph of piperine-treated workers. Piperine decreased DNA methylation levels significantly in the older bees. The compound could have the potential to be a natural diet supplement increasing apian resistance to stress factors.

Published: June 2019

AbstractThe South China Sea (SCS) is a biodiversity hotspot, however, most biodiversity surveys in the region are confined to shallow water reefs. Here, we studied the benthic habitat and fish assemblages in the upper mesophotic coral ecosystems (MCEs; 30–40 m) and SWRs (8–22 m) at three geographic locations (Luzon Strait; Palawan; and the Kalayaan Group of Islands) in the eastern SCS (also called the West Philippine Sea) using diver-based survey methods. Mean coral genera and fish species richness ranged from 17–25 (per 25 m2) and 11–17 (per 250 m2) in MCEs, respectively; although none of these were novel genera/species. Coral and fish assemblages were structured more strongly by location than by depth. Location differences were associated with the variability in benthic composition, wherein locations with higher hard coral cover had higher coral genera richness and abundance. Locations with higher algae and sand cover had higher diversity and density of fish herbivores and benthic invertivores. Fishing efforts may also have contributed to among-location differences as the highly exploited location had the lowest fish biomass. The low variation between depths may be attributed to the similar benthic composition at each location, the interconnectivity between depths due to hydrological conditions, fish motility, and the common fishing gears used in the Philippines that can likely extend beyond SWRs. Results imply that local-scale factors and anthropogenic disturbances probably dampen across-depth structuring in coral genera and fish species assemblages.
Marpa's commands in the Milarepa Life Story
Authors: Pickens John 
Published: June 2019

AbstractIn the Milarepa Life Story the Buddhist teacher Marpa issues many commands to his student, Milarepa, his wife, Dakmema, and his co-religionist, Lama Ngokpa. In these commands the co-occurrence of the imperative stem (skul tshig) and a given pronoun or vocative (khyod, bu, rang re, etc.) indicates a varying level of distance between himself and the addressee. Marpa's speech is also nuanced by the use of pronouns, vocatives, and nicknames across a variety of registers. Marpa's interlocutors, however, invariably use honorific titles and the deferential verb zhu ba to make their requests. The contrast highlights Marpa's authority, as his speech alone determines how close he is with an interlocutor at a given time.
The Roman Military Presence at Dalswinton, Dumfriesshire: a Reassessment of the Evidence from Aerial, Geophysical and LiDAR Survey
Authors: Hanson W.S. , Jones R.E. , Jones R.H. 
Published: June 2019

ABSTRACTThe Roman military presence at Dalswinton is reassessed using a range of remote sensing techniques (geophysical survey, LiDAR and aerial photography). At Bankfoot the absence of internal buildings suggests the postulated vexillation fortress was a more temporary structure; while numerous pits/ovens were identified across the interior of the large Stracathro-type camp. The primary fort at Bankhead was provided with in-turned entrances and two small annexes attached to the north-west and south-east quadrants of the fort. A third much larger annexe extended southwards down to the river. Only pits and furnaces were recorded within the annexes, two of which were expanded in Phase 2. Various buildings, including legionary and auxiliary barracks, were identified in the expanded fort of Phase 2, whose orientation remained unchanged. A mixed garrison of legionaries and auxiliary cavalry is indicated for both periods of occupation. Finally, the fort was deliberately demolished. The Roman attribution of the three nearby enclosures at Butterhole Brae can no longer be supported.
