Joint Optimization of Energy-Harvesting-Powered Two-Way Relaying D2D Communication for IoT: A Rate–Energy Efficiency Tradeoff

Device-to-device (D2D) communication is a key enabling technology to facilely realizing the Internet of Things (IoT) due to its spectral and energy efficiencies features. Exploiting the physical-layer network coding (PNC) and energy harvesting (EH) technology, two-way relaying (TWR) D2D communication can achieve significant performance for IoT in terms of data rate and energy efficiency (EE). In this article, we investigate the EH-aided TWR D2D communication sharing the uplink (UL) spectrum of the traditional cellular networks. We assume that the D2D transmitters, receivers, and participating relays can collect renewable energy (RE) from natural resources. Also, the relays are considered to be powered by radio-frequency (RF) signals utilizing the power splitting (PS) protocol. Subject to the Quality of Service (QoS), power, subchannel assignment, EH, and maximum practical power constraints, two nonconvex mixed-integer nonlinear programming (MINLP) problems are formulated. The two problems provide a tradeoff on either maximizing the TWR D2D link (TDL) rate or its EE depending on the IoT application needs. Based on the particle swarm optimization (PSO) algorithm, we propose the rate and EE tradeoff EH-based algorithm (REET-EH) to deal with these problems. The proposed algorithm can optimally perform the resource allocation (RA), PS factors determination, power allocation (PA), and relay selection processes. The numerical results investigate the performance of the REET-EH algorithm and show its consistency over several parameters. Also, the results illustrate that our proposed algorithm improves the system performance compared with other state-of-the-art algorithms with regard to the D2D link rate and EE.
Role of Medicinal Plants of Traditional Use in Recuperating Devastating COVID-19 Situation

In the present scenario of COVID-19 strike and lack of potential antiviral medicines/vaccines against this extremely contagious lethal infection, identifying potential natural plant sources that can help in fighting this disease either by being viricidal or by boosting the immune system can provide significant therapeutic support. Around the globe as of 26th July 2020, there is ~15.78 million confirmed cases and 0.64 million deaths. The COVID-19 infection is produced by virulent Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) virus, which belongs to large corona virus family. These viruses are responsible for many recent infection outbreaks, SARS in 2003, MERS (Middle East Respiratory Syndrome) in 2012 and recent most fatal COVID-19. Also, mortality rate related to COVID-19 is found to be very high in case of people with weak immune system e.g. elderly patients, children or patients with preexisting health problems. In this relevance, medicinal plants can act as potential healing agents that can help people to fight against this infection by boosting their immune system or by posing viricidal effect. And thus, can contribute in reducing mortality rate related to SARS-CoV-2 infections. In this review, we attempted to compile and discuss different traditional medicinal plants and their bioactive components that help in strengthening our immune system and also play key role in combatting microbial infections including COVID-19. This article will help researchers and industries to identify and scrutinize potential medicinal plants that can meet their interests for various applications including development of herbal/Ayurvedic antiviral drugs, designing antimicrobial/antiviral materials, development of immunopotentiator, preparation of potential sanitizer systems etc.
Leadership Adapted: Towards an Understanding of How Western-Developed Leadership Theories are Translated and Practiced in the Modern Arab Middle East

The purpose of this study is to understand how western-developed leadership theories are translated and practiced in the Modern Arab Middle East (MAME). Over the past century the notion of leadership has progressed through phases of understanding, definition, and practice. This evolution continues today and is no longer contained to the academic and practice-oriented institutions of North America and Europe. Through western-styled educational institutions and professional industries, western-developed leadership theories have stretched around the globe, including the MAME. While this is known, what is much less understood is how these theories are adopted and adapted. This study’s objective is to understand what theories of leadership are taught at Master of Business Administration (MBA) programs in the Modern Arab Middle East and how are they applied in local contexts. The research design was qualitative, interpretivist, and exploratory in nature. Data was collected from the MBA programs, their faculty alumni, and by the observations of the researcher. Publicly available documents were gathered by from online sources and during visits to the programs. Interviewed with respondents were conducted both in-person and through phone and digital conversations. Documents and transcripts were catalogued and thematically analyzed with the resulting themes constituting the findings of the study. The first set of findings centers around the question of how leadership is situated as well as what leadership theories are taught and how. It was found that leadership is professed to be highly valued, is broadly defined, and that is taught through traditional educational methods. The second set of findings pertain to what practitioners do with this education. It was found that leadership was spoken of in nine ways: local, regional, and internationally; a changing environment; entrepreneurship; family business; management preferred over leadership, and professional or personal development. Additionally, respondents reported that they experience the concept of leadership to be enigmatic, for a few, and future oriented. This study is hoped to be one of a series to come that considers how westernleadership theory is used in the MAME with an aim that theory may be useful and congruent within local and regional contexts.

Effect of stubble-height management on crown temperature of perennial ryegrass, tall fescue and chicory

Defoliating pasture to shorter stubble heights (height above the soil surface) may increase temperature at the plant crown (plant–soil interface). This is especially relevant to summer C3 pasture production in parts of south-eastern Australia, where above-optimal ambient temperatures (≥30°C) are often recorded. A rainfed field experiment in north-west Tasmania, Australia, quantified the effect of stubble-height management on the upper distribution of crown temperatures (90th and 75th percentiles) experienced by three pasture species: perennial ryegrass (Lolium perenne L.), tall fescue (Festuca arundinacea Schreb.; syn. Schedonorus arundinaceus (Schreb.) Dumort. ; syn. L. arundinaceum (Schreb.) Darbysh. ), and chicory (Cichorium intybus L.). Three stubble-height treatment levels were evaluated: 35, 55 and 115mm. Defoliation to shorter stubble heights (35 or 55mm cf. 115mm) increased the crown temperature of all species in the subsequent regrowth cycle (period between successive defoliation events). In the second summer, defoliating to shorter stubble heights increased the 90th percentile of crown temperature by an average of 4.2°C for perennial ryegrass, 3.6°C for tall fescue and 1.8°C for chicory. Chicory and second-year tall fescue swards experienced less-extreme crown temperatures than perennial ryegrass. This may partly explain why these two species often outyield perennial ryegrass in hotter summer environments than north-west Tasmania, and hence the increasing interest in their use.
Bidirectional effects of anxiety and anorexia nervosa: A Mendelian randomization study

Objectives To assess bidirectional effects of anxiety and anorexia nervosa (AN) phenotypes. Design Two-sample Mendelian randomization. Setting Genome-wide association study (GWAS) summary statistics from the Psychiatric Genomics Consortium (PGC), analysis of the UK Biobank sample, and Anxiety Neuro Genetics Study (ANGST) consortium. Participants European descent participants from the PGC (n = 14,477), UK Biobank (n = 348,219), and ANGST consortium (n = 17,310, and n = 18,186). Main outcome measures AN diagnosis, worry, anxiety disorder pathology (case-control and quantitative phenotypes). Results We found evidence of a moderate genetic correlation between worry and AN (Rg = 0.36, SE = 0.05, p < 0.001), and the Mendelian randomization analysis supported a causal influence of worry on AN (OR = 2.14, 95% CI: 1.18 to 3.90, p = 0.01). There was no clear evidence for a causal effect of AN on worry in this study (B = −0.01, 95% CI: −0.03 to 0.02, p = 0.55). There was no robust evidence for a causal influence of anxiety disorders on AN (for case-control anxiety disorder phenotype: OR = 1.02, 95% CI: 0.69, 1.50, p = 0.922; for quantitative anxiety disorder phenotype: OR = 4.26, 95% CI: 0.49, 36.69, p = 0.187). There was no robust evidence for a causal effect of AN on anxiety disorders (for case control anxiety disorder phenotype: OR = 1.00, 95% CI: 0.72, 1.38, p = 0.981; for quantitative anxiety disorder phenotype: B = 0.01, 95% CI: −0.06, 0.6=09, p = 0,761). AN and anxiety disorder phenotypes were not genetically correlated (for case-control anxiety disorder phenotype: Rg = 0.10, se = 0.17, p = .56; for quantitative anxiety disorder phenotype: Rg = 0.12, SE = 0.17, p = 0.47). Conclusions Findings support a role for worry in AN development, highlighting a potential target of future AN prevention efforts. Mechanisms underlying the association should be a focus of future investigation. The relatively small sample sizes of anxiety disorder and AN GWASs may have limited power to detect causal effects; these associations should be studied further.
General Height-Diameter Equation Depending on the Stand Variables, for Eucalyptus benthamii

1Universidade do Oeste de Santa Catarina, Xanxere, SC, Brasil Abstract The aim of this study was to develop a general applicability equation to represent the hypsometric relationship of Eucalyptus benthamii Maiden et Cambage stands in Irani, Santa Catarina. The data came from a continuous forest inventory, with a simple random sampling design and the Bitterlich method. The functions to represent the hypsometric relationship were adjusted with their parameters linear function of stands variables, based on the Gauss-Newton algorithm. The models were evaluated according to the criteria of adjustment and precision, accuracy and validation. In general, the Harrison model, adjusted with the coefficient “c” linear function of age, dominant diameter and basal area, presented the best statistical performance to represent the hypsometric relationship of Eucalyptus benthamii.
Response of Tomato (Solanum Lycopersicum) to Deficit Irrigation in Raya Valley, Northern Ethiopia

Water scarcity, erratic rainfall distribution and better management of water are a major constraint for the production of food in arid and semi-arid areas. Therefore, to cope up this problem deficit irrigation and application of irrigation systems are important concerns to achieve the goal of reducing irrigation water use and increase water productivity without significant yield loss under scarce water resources. A field experiment was carried out at Mehoni Agricultural Research Center, Raya Valley of Ethiopia, with objective of to identify the level of deficit irrigation which allow achieving optimum yield and to investigate the effect of alternate, fixed and conventional furrow irrigation method on yield and water productivity. The treatment were three deficit irrigation levels (50, 75 and 100% ETc), and three furrow irrigation methods (conventional, alternate and fixed furrow) were laid out in a random complete block design (RCBD) with three replications. The highest yield was obtained from combination of convectional furrow irrigation method with 100% ETc, convectional furrow irrigation method with 75% ETc and alternative furrow irrigation method with 100% ETc respectively without statistically difference. The highest water productivity of tomato was recorded from alternative furrow irrigation method followed by fixed furrow irrigation method, while convectional furrow irrigation method was recorded the lowest water productivity. Therefore, it can be concluded that alternative furrow irrigation method with 100% ETC of irrigation level increased water productivity which solve a problem of water shortage without significance reduction in tomato yield.

Lessons from nature for green science and technology: an overview and bioinspired superliquiphobic/philic surfaces

Nature has developed materials, objects and processes that function from the macroscale to the nanoscale. The emerging field of biomimetics allows one to mimic biology or nature to develop nanomaterials, nanodevices and processes which provide desirable properties. The biologically inspired materials and structured surfaces are being explored for various commercial applications. These should have minimum human impact on the environment, leading to eco-friendly or green science and technology. There are a large number of flora and fauna including bacteria, plants, land and aquatic animals, and seashells with properties of commercial interest. The paper presents an overview of the general field of biomimetics followed by a detailed overview of mechanisms, fabrication techniques and characterization of superliquiphobic/philic surfaces and their applications. This article is part of the theme issue ‘Bioinspired materials and surfaces for green science and technology’.
The role of herbivore-induced plant volatiles (HIPVs) as indirect plant defense mechanism in a diverse plant and herbivore species; a review

When plants are attacked by herbivores, they release plant volatiles called herbivore-induced plant volatiles (HIPVs) to the environment to communicate with higher trophic levels. HIPVs play different ecological roles such as plant-plant interaction, plant-herbivore interaction, tritrophic interaction and other related interactions. Attractiveness of HIPVs to natural enemies in a tritrophic interaction varies depending on species diversity. Under natural and multiple cropping systems, tritrophic interaction is expected to be more complex than single tritrophic interaction with one species per trophic level. In complex tritrophic interaction, diversity of different trophic levels affects attractiveness of HIPVs to natural enemies. From plant diversity point of view, HIPVs mixture emanating from herbivore-damaged multiple plant species are reported to affect behavioral responses and foraging behavior of natural enemies under laboratory and field conditions. Similarly, from herbivore diversity point of view, in nature, plants are commonly attacked by more than one herbivore species. C onstituents of HIPVs vary between plants infested by multiple and single herbivore species and this affects the behavioral responses and foraging behavior of natural enemies. T his paper reviews recent findings on the role of HIPVs as indirect plant defense in systems with simple tritrophic interaction, and in diverse plants species and diverse herbivore species.
Experimental investigations of a semi-batch Taylor vortex reactor using hexane and water

Two phase Taylor-Vortex reactors have been receiving increased attention due to its capacity to generate emulsions within the system. This dissertation focuses on understanding a Taylor-Vortex (TV) system when operating in a semi-batch manner. Optical experiments were aimed at identifying patterns and distributions that would aid in system operation as well as to better understand the canonical Taylor-Couette flow when multiple phases are involved. Using two immiscible liquids, hexane and water, in the semi-batch TV system, droplet patterns were identified in the system in order to create a flow regime map. The regime map identified four unique stages of banding and non-banding, indicating scenarios where Taylor vortices present in the system are either strong enough to trap droplets or ineffective in compensating for the force of rising buoyant droplets. Further optical investigation of the system identified three unique droplet size distributions, a unimodal distribution, a bi-modal distribution, and a right-skewed distribution. Additionally, the droplet sizes were investigated in relation to the system operation parameters. It was concluded that the droplet sizes and distribution had a strong dependence on the entry conditions of the dispersed phase and did not correlate to the flow patterns identified in the primary investigation of the system. The investigation of the entry conditions shed further insight into the drop sizes and distributions through the identification of jet breakup modes consistent with classical immiscible liquid jet systems, albeit in a narrow channel and a rotating fluid.

Bioenergy Production on Degraded Land: Landowner Perceptions in Central Kalimantan, Indonesia

Bioenergy production from degraded land provides an opportunity to secure a new renewable energy source to meet the rapid growth of energy demand in Indonesia while turning degraded land into productive landscape. However, bioenergy production would not be feasible without landowner participation. This study investigates factors affecting landowners’ preferences for bioenergy production by analyzing 150 landowners with fire experience in Buntoi village in Central Kalimantan using Firth’s logistic regression model. Results indicated that 76% of landowners preferred well-known species that have a readily available market such as sengon (Albizia chinensis (Osb.) Merr. ) and rubber tree (Hevea brasiliensis Müll.Arg.) for restoration on degraded land. Only 8% of preferred nyamplung (Calophyllum inophyllum L.) for bioenergy production; these particular landowners revealed a capacity to handle the uncertainty of the bioenergy market because they had additional jobs and income, had migrated from Java where nyamplung is prevalent, and preferred agricultural extension to improve their technical capacity. These results contribute to identifying key conditions for a bottom-up approach to bioenergy production from degraded land in Indonesia: a stable bioenergy market for landowners, application of familiar bioenergy species, and agricultural extension support for capacity building.

Effect of Intramuscular Administration of Trypadim, Trypamidium and Novidium on Body Temperature, Body Weight and Hematological Parameters of Wistar Rats Infected with Trypanosoma brucei brucei (Federe Strain)

Effect of intramuscular administration of Trypanocides on body temperature, body weight and hematological parameters of Wistar rats infected with Trypanosoma brucei brucei was investigated. Twenty-five adult Wistar rats were randomly divided into 5 groups. Group A uninfected untreated, group B were infected with 1×10 of the parasites. Groups C, D and E were administered the same dose as in group B and were treated with 3.5 mg/kg b.w. of Trypadim (Diminazene di-aceturate); 1 mg/kg b.w. of Trypamidium (Isometamidium chloride) and 1 mg/kg b.w. of Novidium (Homidium chloride), respectively. PCV, WBC, Neutrophil were significantly (p<0.05) higher in groups C, D and E compared to group B. However, the same level of significance (p<0.05) was observed for eosinophil but in a decreasing pattern. Body temperature increased consistently in all groups except group A. There was a significant (p<0.05) difference in all treated groups compared to group B on day 7 and 28 postinfection. Body weight decreased significantly (p≤0.01) in group B compared to the initial and final values. Both vitamins in their separate administration demonstrated trypanocidal and anti-pyrexia activities and therefore we recommend further studies of their combined usage in order to evaluate its synergistic effect in combating or ameliorating the problem of drug resistance in trypanosomiasis.
