A 12-pulse rectifier with passive harmonic reduction based on UIPT in more electric aircrafts
Authors: Abdollahi Rohollah 
Published: March 2021

Purpose
The purpose of this paper is to provide a T autotransformer based 12-pulse rectifier with passive harmonic reduction in more electric aircraft applications. The T autotransformer uses only two main windings which result in volume, space, size, weight and cost savings. Also, the proposed unconventional inter-phase transformer (UIPT) with a lower kVA rating (about 2.6% of the load power) compared to the conventional inter-phase transformer results in a more harmonic reduction.

Design/methodology/approach
To increase rating and reduce the cost and complexity of a multi-pulse rectifier, it is well known that the pulse number must be increased. In some practical cases, a 12-pulse rectifier (12PR) is suggested as a good solution considering its simple structure and low weight. But the 12PR cannot technically meet the standards of harmonic distortion requirements for some industrial applications, and therefore, they must be used with output filters. In this paper, a 12PR is suggested, which consists of a T autotransformer 12PR and a passive harmonic reduction (PHR) based on the UIPT at direct current (DC) link.

Findings
To show the advantage of this new combination over other solutions, simulation results are used, and then, a prototype is implemented to evaluate and verify the simulation results. The simulation and experimental test results show that the input current total harmonic distortion (THD) of the suggested 12PR with a PHR based on UIPT is less than 5%, which meets the IEEE 519 requirements. Also, it is shown that in comparison with other solutions, it is cost effective, and at the same time, its power factor is near unity, and its rating is 29.92% of the load rating. Therefore, it is obvious that the proposed rectifier is a practical solution for more electric aircrafts.

Originality/value
The contributions of this paper are summarized as follows. The suggested design uses a retrofit T autotransformer, which meets all technical constraints, and in comparison, with other options, has less rating, weight, volume and cost. In the suggested rectifier, a PHR based on UIPT at its dc link of 12PR is used, which has good technical capabilities and lower ratings. In the PHR based on UIPT, an IPT is used, which has an additional secondary winding and four diodes. This solution leads to a reduction in input current THD and conduction losses of diodes. In full load conditions, the input line current THD and power factor are 4% and 0.99, respectively. The THD is less than 5%, which satisfies IEEE-519 and DO-160G requirements.
How do paving and planting strategies affect microclimate conditions and thermal comfort in apartment complexes?
Authors: Choi Ga Yoon , Kim Hwan Sung , Kim Hyungkyoo , Lee Jae Seung 
Published: March 2021

Purpose
In cities with high density, heat is often trapped between buildings which increases the frequency and intensity of heat events. Researchers have focused on developing strategies to mitigate the negative impacts of heat in cities. Adopting green infrastructure and cooling pavements are some of the many ways to promote thermal comfort against heat. The purpose of this study is to improve microclimate conditions and thermal comfort levels in high-density living conditions in Seoul, South Korea.

Design/methodology/approach
This study compares six design alternatives of an apartment complex with different paving and planting systems. It also examines the thermal outcome of the alternatives under normal and extreme heat conditions to suggest strategies to secure acceptable thermal comfort levels for the inhabitants. Each alternative is analyzed using ENVI-met, a software program that simulates microclimate conditions and thermal comfort features based on relationships among buildings, vegetation and pavements.

Findings
The results indicate that grass paving was more effective than stone paving in lowering air temperature and improving thermal comfort at the near-surface level. Coniferous trees were found to be more effective than broadleaf trees in reducing temperature. Thermal comfort levels were most improved when coniferous trees were planted in paired settings.

Practical implications
Landscape elements show promise for the improvement of thermal conditions because it is much easier to redesign landscape elements, such as paving or planting, than to change fixed urban elements like buildings and roads. The results identified the potential of landscape design for improving microclimate and thermal comfort in urban residential complexes.

Originality/value
The results contribute to the literature by examining the effect of tree species and layout on thermal comfort levels, which has been rarely investigated in previous studies.
A critical examination of the role of public participation in petroleum development contract in Nigeria
Authors: Odion Job Ohioma 
Published: March 2021

Purpose
The topic is examined with a view to ascertaining the various methods by which indigenous oil companies can participate in petroleum development contract in Nigeria. Also, the raison d’etre of the policy will be considered to see whether the government has achieved its primary aim and how successive government has approach the issue with a view to determining the best policy to adopt. The challenges facing this policy will be considered with a view to unfold whether the Petroleum Industry Bill proffers solution.

Design/methodology/approach
This methodology of research is doctrinaire and analytical. The author used the available statute and case law in extrapolation of the views expressed in this paper; where necessary, secondary data as sourced from existing literature was used.

Findings
This paper revealed that the existing laws in Nigeria do not support public participation in the petroleum sector. so much is in the hands of the government. The paper also found that this government's monopoly of the sector is one of the reasons for the slow level of development in the sector.

Originality/value
This paper is original to the extent that it focusses on a relatively new area of public participation in the upstream petroleum sector in Nigeria. Most papers have often focussed on the downstream sector; however, this study seeks to re-direct the debate to the upstream sector.

Published: March 2021

AbstractSchools continue to experience difficulty meeting the needs of young children who are formally identified as having an emotional and/or behavioural disorder (EBD). Although schools are mandated to use evidence‐based practices to improve student outcomes, such practices must first be identified before they can be employed. Systematic reviews of intervention studies are commonly performed to identify evidence‐based practices, make recommendations for service delivery, and identify areas for future research that are needed to inform practice. At this time, researchers have yet to perform a systematic review of intervention studies involving young children identified with EBD – early childhood (EC) – grade 2. The purpose of this study was to identify and describe published school‐based intervention research for this student population. Studies meeting selection criteria were evaluated according to the relevant What Works Clearinghouse (WWC) Design standards to identify studies with strong internal validity that reported positive effects. Twenty‐nine manuscripts reporting 30 intervention studies were identified. Findings suggest that practitioners must primarily rely on their professional judgement and values guided by principles embedded in their training when planning instruction and support for young children with EBD due to the absence of high‐quality intervention research. Additional rigorous evaluations are needed so that practice is better informed by science. Recommendations for practice, areas for future research, and study limitations are discussed.
Why did New Zealand's referendum to legalise recreational cannabis fail?
Authors: Rychert Marta , Wilkins Chris 
Published: March 2021

AbstractNew Zealand recently held the world's first national referendum on cannabis legalisation involving a detailed bill to regulate retail sale and supply of cannabis for recreational (non‐medical) adult use (i.e. the Cannabis Legalisation and Control Bill; CLCB). The referendum generated significant domestic debate and lobbying from both sides of the issue. The CLCB was narrowly defeated, with 48.4% voting to support versus 50.7% opposed. In this commentary, we discuss the referendum campaigns and other political and social factors that may have contributed to the result. Voting patterns appeared to largely follow traditional conservative‐liberal, urban–rural and age divides. The referendum format created a public campaigning environment that encouraged persuasion and selective use of evidence rather than rational discussion of all the evidence and related knowledge gaps. The self‐imposed neutrality of the centre left Labour Party and its popular leader may have been a decisive factor in the narrow defeat. It did not appear to be the case that anti‐CLCB groups outspent the pro‐CLCB movement in online promotional advertisements, and the leading digital media appeared largely neutral or mildly in favour of reform. The recent New Zealand experience illustrates the uncertainties of attempting to achieve cannabis law reform via a public referendum vote.
Could a drug‐checking service increase intention to use ecstasy at a festival?
Authors: Murphy Sherri , Bright Stephen J. , Dear Greg 
Published: March 2021

AbstractIntroductionCalls to provide sanctioned drug‐checking (pill testing) at Australian music festivals have been met with resistance from most governments due to concerns that such services would increase use of ecstasy and other drugs. We investigated that concern and used the Theory of Planned Behaviour to examine the determinants of intention to use a drug‐checking service.MethodsData were collected over a 3‐day period at a music festival in Western Australia. Participants (n = 247; 50% male; 52% aged 25–34 years) were presented with three hypothetical pill testing scenarios: no testing provided, onsite testing provided and fixed offsite testing provided.ResultsNeither ecstasy users (n = 212) nor participants who had never used ecstasy (n = 35) reported an increased intention to use ecstasy in scenarios in which drug checking was provided. The combination of attitudes, subjective norms and perceived behavioural control predicted intention to use a fixed site drug‐checking service, while only subjective norms predicted intention to use an onsite service.Discussion and ConclusionsThese data do not support the view that offering a drug‐checking service at a festival will result in ecstasy use by people who have never used ecstasy or lead to increased use among people who use ecstasy.

Published: March 2021

AbstractCongenital aneurysm of the ductus arteriosus is reported in 0.8% in neonatal autopsies; however, true incidence is unknown because of high rate of asymptomatic cases and spontaneous regression. Possible complications in symptomatic cases are thromboembolism, spontaneous rupture, erosion, infection, compression of airways, and death. In this report, we present a newborn with giant ductus arteriosus aneurysm (DAA) diagnosed in first day of life, surgically treated after thrombosis of aneurysm.
DynaMETE: a hybrid MaxEnt‐plus‐mechanism theory of dynamic macroecology
Authors: Harte John , Umemura Kaito , Brush Micah 
Published: March 2021

AbstractThe Maximum Entropy Theory of Ecology (METE) predicts the shapes of macroecological metrics in relatively static ecosystems, across spatial scales, taxonomic categories and habitats, using constraints imposed by static state variables. In disturbed ecosystems, however, with time‐varying state variables, its predictions often fail. We extend macroecological theory from static to dynamic by combining the MaxEnt inference procedure with explicit mechanisms governing disturbance. In the static limit, the resulting theory, DynaMETE, reduces to METE but also predicts a new scaling relationship among static state variables. Under disturbances, expressed as shifts in demographic, ontogenic growth or migration rates, DynaMETE predicts the time trajectories of the state variables as well as the time‐varying shapes of macroecological metrics such as the species abundance distribution and the distribution of metabolic rates over individuals. An iterative procedure for solving the dynamic theory is presented. Characteristic signatures of the deviation from static predictions of macroecological patterns are shown to result from different kinds of disturbance. By combining MaxEnt inference with explicit dynamical mechanisms of disturbance, DynaMETE is a candidate theory of macroecology for ecosystems responding to anthropogenic or natural disturbances.

AbstractAcute high‐altitude (HA) exposure induces physiological responses of the heart and blood pressure (BP). However, few studies have investigated the responses associated with dipper and non‐dipper BP patterns. In this prospective study, 72 patients underwent echocardiography and 24‐h ambulatory BP testing at sea level and HA. Patients were divided into dipper and non‐dipper groups according to BP at sea level. Acute HA exposure elevated 24‐h systolic and diastolic BP and increased BP variability, particularly in the morning. Moreover, acute exposure increased left ventricular torsion, end‐systolic elastance, effective arterial elastance, and untwisting rate, but reduced peak early diastolic velocity/late diastolic velocity and peak early diastolic velocity/early diastolic velocity, implying enhanced left ventricular systolic function but impaired filling. Dippers showed pronounced increases in night‐time BP, while non‐dippers showed significant elevation in day‐time BP, which blunted differences in nocturnal BP fall, and lowest night‐time and evening BP. Dippers had higher global longitudinal strain, torsion, and untwisting rates after acute HA exposure. Variations in night‐time systolic BP correlated with variations in torsion and global longitudinal strain. Our study firstly demonstrates BP and cardiac function variations during acute HA exposure in different BP patterns and BP increases in dippers at night, while non‐dippers showed day‐time increases. Furthermore, enhanced left ventricular torsion and global longitudinal strain are associated with BP changes. Non‐dippers showed poor cardiac compensatory and maladaptive to acute HA exposure. However, the exact mechanisms involved need further illumination.

AbstractVarious lymph node functions are regulated by the sympathetic nervous system as shown in rodent studies. If human lymph nodes show a comparable neural regulation, their afferent nerves could represent a potential therapeutic target to treat, for example, infectious or autoimmune disease. Little information is available on human lymph node innervation and the aim of this study is to establish a comprehensive and accurate representation of the presence and location of sympathetic nerves in human lymph nodes. Since previous studies mention sympathetic paravascular nerves to occasionally extent into T cell‐rich regions, the relation of these nerves with T cells was studied as well. A total number of 15 inguinal lymph nodes were resected from six donated human cadavers. Lymph node sections were stained with HE and a double T/B cell staining for evaluation of their morphology and to screen for general pathologies. A triple stain was used to identify blood vessels, sympathetic nerves and T cells, and, to study the presence and location of sympathetic nerves and their relation to T cells. To evaluate whether the observed nerves were en route to other structures or were involved in local processes, adjacent slides were stained with a marker for varicosities (synaptophysin), which presence is suggestive for synaptic activity. All lymph nodes contained sympathetic nerves, both as paravascular and discrete structures. In 15/15 lymph nodes, nerves were observed in their capsule, medulla and hilum, whereas only 13/15 lymph nodes contained nerves in their cortex. The amount of sympathetic nerves varied between compartments and between and within individuals. In general, if a lymph node contained more paravascular nerves in a specific compartment, more discrete nerves were observed as well. Occasionally, discrete nerves were observed in relation to T cells in lymphoid tissues of the cortex and medulla. Furthermore, discrete nerves were frequently present in the capsule and hilum. The presence of varicosities in a portion of these nerves, independently to their compartment, suggested a local regulatory function for these nerves. Human lymph nodes contain sympathetic nerves in their capsule, trabeculae, cortex, medulla and hilum, both as paravascular or as discrete structures. Discrete nerves were observed in relation to T cells and non‐T cell‐rich areas such as the hilar and capsular connective tissue. The presence of discrete structures suggests neural regulation of structures other than blood vessels, which was further supported by the presence of varicosities in a portion of these nerves. These observations are of relevance in further understanding neural regulation of lymph node immune responses and in the development of neuromodulatory immune therapies.

AbstractSolitary chemosensory cells and chemosensory cell clusters are distributed in the pharynx and larynx. In the present study, the morphology and reflexogenic function of solitary chemosensory cells and chemosensory cell clusters in the nasal cavity and pharynx were examined using immunofluorescence for GNAT3 and electrophysiology. In the nasal cavity, GNAT3‐immunoreactive solitary chemosensory cells were widely distributed in the nasal mucosa, particularly in the cranial region near the nostrils. Solitary chemosensory cells were also observed in the nasopharynx. Solitary chemosensory cells in the nasopharyngeal cavity were barrel like or slender in shape with long lateral processes within the epithelial layer to attach surrounding ciliated epithelial cells. Chemosensory cell clusters containing GNAT3‐immunoreactive cells were also detected in the pharynx. GNAT3‐immunoreactive cells gathered with SNAP25‐immunoreactive cells in chemosensory clusters. GNAT3‐immunoreactive chemosensory cells were in close contact with a few SP‐ or CGRP‐immunoreactive nerve endings. In the pharynx, GNAT3‐immunoreactive chemosensory cells were also attached to P2X3‐immunoreactive nerve endings. Physiologically, the perfusion of 10 mM quinine hydrochloride (QHCl) solution induced ventilatory depression. The QHCl‐induced reflex was diminished by bilateral section of the glossopharyngeal nerve, suggesting autonomic reflex were evoked by chemosensory cells in pharynx but not in nasal mucosa. The present results indicate that complex shape of nasopharyngeal solitary chemosensory cells may contribute to intercellular communication, and pharyngeal chemosensory cells may play a role in respiratory depression.

Decolonial Translation: Destabilizing Coloniality in Secular Translations of Islamic Law
Authors: Salaymeh (لينا سلايمة) Lena 
Published: March 2021

Abstract
Contemporary Islamic legal studies – both inside and outside the Muslim world – commonly relies upon a secular distortion of law. In this article, I use translation as a metonym for secular transformations and, accordingly, I will demonstrate how secular ideology translates the Islamic tradition. A secular translation converts the Islamic tradition into “religion” (the non-secular) and Islamic law into “sharia” – a term intended to represent the English mispronunciation of the Arabic word شريعة (sharīʿah). I explore the differences between historical Islamic terms and secular terms in order to demonstrate that coloniality generates religion and religious law; in turn, these two notions convert شريعة (sharīʿah) into “sharia” in both Arabic and non-Arabic languages. Consequently, the notion of “sharia” is part of a colonial system of meaning.
