Authors: LaVallee Chris , Rascati Karen L. , Gums Tyler H.
Published: September 2020

Hypertension affects approximately one‐third of the US adults. This study investigated antihypertensive utilization patterns among hypertensive patients who were prescribed treatment, yet still experienced uncontrolled hypertension. Data from the Decision Resources Group Real World Evidence Data Repository US database (2015‐2016) were used to construct a cohort of uncontrolled hypertension patients to observe antihypertensive utilization patterns. Results for 5059 patients, with an average age of 57.8 (SD = 13.7), who had, on average 2.4 agents prescribed. Approximately half (51.9%) were female, and most were White (86.8%). More than one‐third (N = 1877; 37.1%) of patients were diagnosed with diabetes mellitus (DM) or chronic kidney disease (CKD) that could independently contribute to increased cardiovascular complications. Overall, the most common treatments prescribed, as percent of agents and as percent of patients, respectively, were diuretics (24.9%; 59.6%), followed by angiotensin‐converting enzyme inhibitors (ACEIs) (23.8%; 56.9%), beta‐blockers (BBs) (18.7%; 44.8%), calcium channel blockers (CCBs) (15.4%; 36.8%), and angiotensin II receptor blockers (ARBs) (13.5%; 32.3%). Approximately one‐tenth (10.5%) of the prescriptions were written for fixed‐dose combination therapies. Among patients diagnosed with DM and CKD (N = 200), the order of the most common agents was the same as the overall cohort. Only 5.6% of prescriptions written for these patients were fixed‐dose combination therapy. Based on clinical guidelines, which suggest using ACEIs, ARBs, or CCBs as first‐line therapy, and fixed‐dose combination therapy to increase adherence, this indicates over‐prescribing of BBs and under‐prescribing of fixed‐dose combination therapy. These findings illustrate the need to further investigate challenges faced by patients and providers in treatment decision‐making.

Published: September 2020

Accurate characterization of oocyte development is essential to understanding foundational aspects of reproductive biology and successful management of Pacific halibut (Hippoglossus stenolepis). Here this study provides complete histological descriptions for eight oocyte developmental stages in addition to postovulatory follicles and demonstrates the potential for oocyte size frequency distribution to act as a proxy for ovarian developmental stage and future maturity assessments. Importantly, it provides the first histological evidence that Pacific halibut have a group‐synchronous ovarian developmental pattern with determinate fecundity and support for their batch‐spawning strategy.
Adolescents’ Interpersonal Negotiation Strategies: Does Competence Vary by Context?
Authors: Baker Elizabeth , Exner‐Cortens Deinera
Published: September 2020

Negotiating conflict in healthy ways is key to adolescents’ social functioning. This paper examines interpersonal negotiation strategies (INS) (a developmental framework for navigating conflict) across three different contexts (friend, romantic, and parent) in a sample of 212 Canadian mid‐adolescents. Adolescents were asked how they would deal with a hypothetical conflict in each context. Adolescents were most advanced at negotiating conflict in the friend context, followed by parent and romantic contexts; negotiation skills were worst in the romantic context. Girls demonstrated a higher level of INS than boys, but only with friends. These results indicate the need for universal healthy relationship programs that support the development of conflict negotiation skills, especially within the new interpersonal context of romantic relationships.

Published: September 2020

The fermented feed has been identified as a potential alternative to antibiotics in feeds that markedly affects gut health and growth performance of pigs. Two recent studies performed in our laboratory investigated that the fermented corn–soybean meal (fermented feed, FF) improved the gut health of pigs. This study was conducted to determine the effect of a FF on the carcass, meat quality, muscle fatty acids profile, muscle amino acid and antioxidant ability of grower‐finisher pigs. In this study, a total of 48 crossbred barrows (Duroc × Landrace × Large White) were randomly divided into 2 treatments with unfermented corn–soybean diet (Ctrl) and FF diet. Compared with control pigs fed a standard diet, the results showed that FF significantly increased the muscle colour of redness and significantly reduced muscle moisture loss rate. Furthermore, FF significantly increased the content of aromatic amino acids such as aspartic acid, glutamic acid and alanine. More importantly, FF increased monounsaturated fatty acid and polyunsaturated fatty acid content. Collectively, FF could be a promising feed strategy in improving meat quality and nutritional value in grower‐finisher pig.
Professional identity of allied health staff associated with a major health network organizational restructuring
Authors: Porter Judi , Wilton Anita
Published: September 2020

Maintenance of professional identity, particularly during periods of organizational restructuring, is critical within modern complex healthcare systems as professional identity contributes to the psychological well‐being of staff and leaders. This study aimed to evaluate change in professional identity of allied health staff associated with a major health network organizational restructuring in Australia. Data were collected from allied health staff in 2017 and 2019, before (n= 226) and after (n= 197) the restructuring. An online questionnaire including the 10‐question Brown's Group Identification Scale that considers the strength of professional identity of the individual with their own professional group was used. Professional identity of allied health staff was high before and after the organizational restructuring, although several individual statements, and overall professional identity, declined significantly post‐restructuring. It was difficult to attribute these changes solely to the restructuring due to some differences in demographic characteristics between the two cohorts. Future studies should seek to understand the effect of other workplace factors on the professional identity of allied health staff. Further research could also investigate allied health professional identity to understand its importance within contemporary healthcare.

Published: September 2020

A clay soil, classified as Clay of High plasticity (CH) according to Unified Soil Classification System (USCS) was stabilized with cement, Rice Husk Ash (RHA) and promoter. The mineralogy of the clay soil and the morphology of the clay and clay specimens admixed with varied composition of cement, RHA and promoter were evaluated in order to determine effect of the RHA on promoter stabilization of cement based clay soil. The promoter used in this study consists of calcium chloride and sodium hydroxide in the ratio of 1:1. The clay was remolded at standard Proctor compaction energy and the specimens were mixed with 0, 1.0, 2.0 and 3.0% cement, admixed with 1.0, 2.0, 3.0% RHA each, and 0.3, 0.6, 1.0% promoter each. The molded specimens were cured for 1, 7, 14, 28, 60 and 90days before testing for Unconfined Compressive Strength (UCS) and consequently the modulus of elasticity. The UCS of specimens without cement increased from 20 kN/m2 for the natural clay soil to 95 kN/m2 on addition of 3% RHA and 1.0% promoter after 28 days of curing, representing 475% increase in the UCS. This increase was confirmed by morphology of the clay soil mixed with RHA and promoter only, which showed presence of calcium silicate hydrate. Addition of 3.0% cement with 3 and 1.0% RHA and promoter respectively, increased the UCS from 220 to 375kN/m2 after 28 days of curing, which was also confirmed by the morphology of the specimens. The highest elastic modulus of 48.3 MPa was observed at specimens containing 3% cement, 3% RHA and 1.0% promoter.

Subsurface basement, structure, stratigraphy, and timing of regional tectonic events affecting the Guajira margin of northern Colombia
Authors: Vence Eleine , Mann Paul
Published: September 2020

We have combined previous data from Mesozoic-Cenozoic outcrops in the Guajira Peninsula of northern Colombia with regional gravity, bathymetric, and seismic interpretations to demonstrate the existence of a 280 km long western extension of the Great Arc of the Caribbean (GAC) along the continental margin of Colombia. Seismic data reveal an 80–100 km wide domal-shaped basement high that exhibits internal chaotic seismic facies. This elongate and domal-shaped structure extends 1800 km from the Aves Ridge in the Caribbean Sea to the study area in offshore Colombia. The western extension of the GAC in Colombia and western Venezuela is buried by 700–3000 m of continental margin sedimentary rocks as a result of the GAC colliding earlier with the Colombian margin (Cretaceous-early Paleogene collision) than its subaerially exposed eastern extension along the Leeward Antilles ridge (late Paleogene-Neogene). Our compilation of geologic information from the entire GAC reveals that GAC magmatism occurred from 128 to 74 Ma with magmatism ages progressively younger toward the east. Six upper Eocene to recent marine seismic sequences overlying the domal basement high of the GAC have been mapped by our analysis of 2400 km of seismic lines and 12 well logs. Based on subsurface mapping correlated with well-log information and onland geology in the Guajira Peninsula, these six sequences record four major deformational events: (1) late Eocene rifting in an east–west direction produced half-grabens in the northern part of the area, (2) Oligocene transtension in the southern part of the area expressed by right-lateral Oligocene strike-slip faulting and extensional basin formation, (3) early-middle Miocene transtension, and (4) late Miocene-early Pliocene Andean uplift accompanied by rapid erosion and clastic infilling of offshore basins by the Magdalena delta and deep-sea fan. The significance of this basin framework is discussed for known and inferred hydrocarbon systems.

Published: September 2020

From the researcher's experience in the field, many students were reluctant to ask for any clarification, unwilling to express their opinion, less able to give feedback, and did disruptive behaviors during the learning process. Ideally, students are expected to be active and involved in the learning process and to get good learning outcomes. This study is a Class Action Research (CAR), which attempts to improve students' activity and learning outcomes. The research was conducted through four main stages: planning, implementation, monitoring, evaluation and reflection. The research findings from teaching the names and responsibilities of angels through the classical method do not obtain maximum result. On the other hand, word guessing learning model shows better results than that of the classical one. In this model, students are motivated to compete with one another in making and answering the questions. The normally passive students are encouraged to participate actively in learning. Thus, it can be concluded that the learning process with of the game will improve students' learning outcomes

Published: September 2020

The paper discusses the designing process of screw conveyors, with regard to the determination of the exploitation parameters of such devices with the use of the Discrete Element
Method (DEM). The influence of the chosen model input parameters on the results of the
simulations was examined. The key parameters which determine the exploitation characteristics of a screw conveyor were identified as follows: the size of a DEM particle, coefficients
of internal and external friction. Experimental measurements of the laboratory screw conveyor provided the actual exploitation characteristics of a device used for the transportation
of a limestone powder. The comparison of the results of the simulations and experiments
gave satisfactory results. For this reason, DEM simulations were identified as an effective
tool for determining and optimization of the construction and exploitation parameters of the
screw conveyors

Published: September 2020

Bacteriological studies of the last time have undoubtedly proved the dependence of infectious diseases on the presence of microorganisms. The latter play an important role in surgery. Various deviations in the healing of wounds, as has now been positively proven, depend precisely on the penetration of pathogenic microbes into them, several types of which are already known. In the first place in terms of frequency and importance are streptococcus pyogenes or streptococcus erysipelatis and various species of staphylococci pyogeni. The tremendous success of modern surgery is associated with these discoveries and with the application of measures to eliminate these microbes from wounded surfaces.

One effort to prevent traffic accidents is to look at the character of road users in the tendency to interpret traffic rules. This study aims to see the influence between experience, decision making and self-justification of the attitude of violation against the flow of traffic in adolescents of high school students in the Capital Special Region of Jakarta. This study used a theoretical study of cognitive dissonance. The conclusion obtained is that the dominant factor in cognitive dissonance is more on the element of behavior change, self experience and the attitude of the decision to commit a violation against the flow of traffic. In contrast to the cognitive dissonance of trust and self-justification, it has a negative effect on the contribution of violating behavior to adolescents in driving. Recommendations that can be used as references by Traffic Police in changing violation behavior against traffic flow in adolescents, by using intimate central parties with them, such as close friends, parents and teachers in their daily interactions.

Salah satu upaya pencegahan kecelakaan lalu lintas adalah dengan melihat karakter pengguna jalan dalam kecenderungan memaknai peraturan lalu lintas. Penelitian ini bertujuan melihat pengaruh antara pengalaman, keputusan melakukan, dan pembenaran diri terhadap sikap melanggar melawan arus lalu lintas pada remaja pelajar SMA di Daerah Khusus Ibukota Jakarta. Penelitian ini menggunakan kajian teoritik disonansi kognitif. Kesimpulan yang diperoleh adalah bahwa faktor dominan pada dissonansi kognitif lebih pada unsur perubahan perilaku, pengalaman diri, dan sikap keputusan melakukan pelanggaran melawan arus lalu lintas. Berbeda dengan itu, pada dissonansi kognitif kepercayaan dan pembenaran diri justru berpengaruh terbalik atau negatif dalam kontribusi dengan perilaku pelanggaran pada remaja dalam berkendara. Rekomendasi yang dapat dijadikan referensi oleh Polisi Lalulintas dalam mengubah perilaku pelanggaran melawan arus lalu lintas pada remaja, dengan menggunakan pihak-pihak sentral yang intim dengan mereka, seperti kawan akrab, orang tua, dan guru dalam interaksi mereka sehari-hari.

Establishing a strategic thinking approach at the University of Zambia
Authors: Msusa Kennedy Ngwende , Chowa Taonaziso
Published: September 2020

The purpose of this study was to establish the use of strategic thinking variables in a public university, the University of Zambia. Nine constructs of strategic thinking variables in this study are framed as strategic thinking general, thinking in time, intently focused, systems perspective, intelligent opportunism, hypothesis-driven, reframing, reflecting, and environmental analysis. A qualitative research design encompassing a review of documents and archival records, direct observation, and sense-making informed the evidence gathered in this study. The pre-strategic thinking phase covers the period 1966 to 1993, while the nascent strategic thinking phase covers the period 1994 to 2012 and the evolutionary strategic thinking phase covers the period 2013 to 2022. The findings of this study have revealed that in the pre-strategic thinking phase, the University was guided by the national development agenda for human capital development. The absence of an Institutional strategic plan and associated strategy documents points to a disconnection between optimal strategy and the strategic intentions of the University managers. In both the nascent strategic thinking phase and the evolutionary phase, significant gaps exist in the utilization of strategic thinking variables thinking in time, reframing, reflecting, environmental analysis, focused intent, and intelligent opportunism. This study suggests the University of Zambia should engage employees in the use of strategic thinking variables, with a view to increasing the chances of organizational success. Further, it seems possible that the hitherto limited use of strategic thinking as a practice in the University of Zambia may be hindering the achievement of organizational set goals. Through this conceptualization, this paper has attempted to fill a gap in strategic thinking literature as it pertains to public universities

Ethics education for contemporary clinical pharmacy practice in Africa
Authors: Okoro Roland N , Jamiu Muslim O
Published: September 2020

The paradigm shift to a patient-centred pharmacy practice model has resulted in dramatic increases in the number and variety of ethical and other dilemmas that confront pharmacists in their routine practice. However, ethical problems may go undetected by many pharmacists in most developing countries. Hence, there is a huge need for sound educational preparation of future pharmacists before they are faced with an urgent decision. This paper highlights the urgent need for pharmacy ethics to be adequately taught in schools of pharmacy, especially at the undergraduate and professional levels, so that future pharmacists can begin their professional careers with adequate ethical knowledge, skills, competencies and experience to detect and resolve ethical dilemmas of the contemporary patient-centred pharmacy practice.

Published: September 2020

Background: Histone deacetylases (HDACs) catalyze histone deacetylation and suppress gene transcription during various cellular processes. Within the superfamily of HDACs, RPD3/HDA1-type HDACs are the most studied, and it is reported that RPD3 genes play crucial roles in plant growth and physiological processes. However, there is a lack of systematic research on the RPD3/HDA1 gene family in cotton.Results: In this study, genome-wide analysis identified 9, 9, 18, and 18 RPD3 genes in Gossypium raimondii, G. arboreum, G. hirsutum, and G. barbadense, respectively. This gene family was divided into 4 subfamilies through phylogenetic analysis. The exon-intron structure and conserved motif analysis revealed high conservation in each branch of the cotton RPD3 genes. Collinearity analysis indicated that segmental duplication was the primary driving force during the expansion of the RPD3 gene family in cotton. There was at least one presumed cis-element related to plant hormones in the promoter regions of all GhRPD3 genes, especially MeJA- and ABA-responsive elements, which have more members than other hormone-relevant elements. The expression patterns showed that most GhRPD3 genes had relatively high expression levels in floral organs and performed higher expression in early-maturity cotton compared with late-maturity cotton during flower bud differentiation. In addition, the expression of GhRPD3 genes could be significantly induced by one or more abiotic stresses as well as exogenous application of MeJA or ABA.Conclusions: Our findings reveal that GhRPD3 genes might be involved in flower bud differentiation and resistance to abiotic stresses, which provides a basis for further functional verification of GhRPD3 genes in cotton development and a foundation for breeding better early-maturity cotton cultivars in the future.

Published: September 2020

The paper considers the reliability level of different distributed generation units. The world comparative statistics of reliability parameters depending on the unit capacity and other influencing factors are presented. The study includes an analysis of possible approaches to the correction of statistical parameters under the particular conditions. The calculation and analysis of structural reliability parameters for a group of distributed generation units is performed. It is shown that conventional N+1 reliability principle is not enough for distributed generation given a great number of operation conditions. A set of N+n principles is proposed according to the required distributed generation reliability level. Considering the reliability parameters is of great importance for the selection of installed power and the structure of distributed generation for industrial and household facilities under the design and evaluation of its technical and economic efficiency. Gradual growth of the share of distributed generation in power and energy balances of power systems raises the issue of its reliability calculation and regulation. The results obtained in the paper are also important for the maintenance, planning of repairs, and providing necessary logistics solution for the delivery of spare parts and consumables to generating plants.

Shadow of Obstacles (SoO) on a PV Panel is classified depending on time with changing pattern of the shadow. Due to obstacles, the performance of a silicon c-Si PV panel reduces by a significant level. Different types of obstacles cast shadow on the panel and interrupt to get irradiation reducing the generated power. The simulation model is implemented in MATLAB/Simulink to observe the changing pattern and variation of output power with changing shadow pattern of the obstacles. The results show identical behaviors. It is clearly viewed in both PV generated I-V and P-V curves. Their pattern of graphs is changed depending on the time for time-dependent obstacles. Graphs pattern is also changed with depending on timeindependent obstacles and that does not vary with time. The identification of the behavior of the obstacle is vital to improve the PV system performance. For time-dependent obstacles and for time independent obstacles power decreases in specific quantity depending on the kind of SoO. Specifically, for the timedepending one is also depend on the duration of the SoO.

The  building  sector  is  partially  in  charge  of  the exhaustion of  conventional  energy  sources,  global  warming,  and environmental   pollution.   This   experimental   investigation   is devoted  to  the  study  of  the  thermal behaviourof  three  different building   materials   used   in   Algeria,   namely   sheep    wool, traditional brick, and ordinary brick, under real conditions. Three identical chambers were built made of the above-citedmaterials. Three  temperature  sensors  were  placed  in  the center of  the  three chambers,  which  were  aligned  and  separated  by  approximately 10 cm. The digital acquisition system based on the Arduino board allows us to measure and record temperatures in the middle of the three  well-closed  rooms  for  one  day  (day  and  night)  by  one-minute   steps.   The   temperature   of   the   ambient   air   (outdoor temperature),used  as  areference,  wastaken  too.  It  is  found  that the   thermo-physical   properties   (thermal   diffusivity)   of   the building  materials,  in  addition  to  the  thickness  of  the  building envelope  (walls  and  roof),  play  an  important  role  in  the  heat exchangebetween  the  indoor  and  outdoor. This  study  aims  to encourage the reuse of the traditional bricks seen their advantages in energy saving and environmental preservation.

In this paper, the quality inspection of a Photovoltaic (PV) power plant under a mismatch effect due to the use of 18 different classes of PV modules from 5 different manufacturers is presented. The quality inspection has been carried out by three different tests; a visual inspection, an infrared (IR) thermography inspection and electrical monitoring. More than 800 IR thermography images have been analyzed to cover all PV modules installed. Some inverters have been electrically monitored to measure electrical parameters, being the focus of this paper the output energy. A PV plant database has been studied to calculate a mismatch power factor of the PV arrays connected in the measured inverters. Mismatch power factor, hot spots and the output energy of the measured inverters have been compared. Results showed that output energy is influenced by the existence of mismatching. In some cases, compared inverters showed a power loss of up to 10%.

The advent of battery energy storage system(BESS) to power systems introduced many ancillary servicesthat make use of fast response of batteries. Frequency controlis one of the most important applications that aid stabilizingelectric networks. Secondary frequency control is one typeof frequency control that uses the BESS to supply/absorbnet power to bring the frequency deviation to its workinglimits. Renewable energy sources increasingly contribute to-wards utilization in microgrids for ancillary services, frequencycontrol for instance. The frequency deviation anomaly is moreprominent in case of adopting renewable energy sources, anda 30 MW wind power source is considered in this study alongwith the selected network in Saudi Arabia for analyzing theproper sizing of the BESS.

Adaptive PI control and active tower damping compensation of a wind turbine
Authors: M. Lara, J. Garrido  , F. Vázquez
Published: September 2020

This  paper  deals  with  the  control  problem  ofa  wind turbine model working in the nominal zone. This process is a    nonlinear    system    whose    dynamics    vary    strongly depending  on  the operation  point.  In  the  nominal  region, the wind turbine speed is controlled by means of the pitch angle    to    generate    the    nominal    power.    The    wind fluctuations  and  its  non-uniform  special  profile  act  as disturbances   on   the   power   generation   and   the   tower deflections. These oscillations must be reduced to improve the wind turbine lifetime. In  this  work,  an adaptive  control  structure  operating on the pitch variable is proposed. It is composed of a gain-scheduling     PI     control,     an adaptivefeedforward compensation  of  the  wind  speed  and  an adaptive  gain compensation  for  the  tower  damping.  The  tuning  of  the controller  parameters  is  formulated  as  an  optimization problem  that  minimizes  the  tower  fore-aft  displacements and  the  deviation  of  the  wind  turbine  speed  from  its nominal  value.  It  is  resolved  using  genetic  algorithms  for different   linear   models   that   are   obtained   from   the nonlinear model. The  proposed  controller  is    compared with  a  classical baseline   PI   (Proportional-integral)   controller   and the simulation  results  show  a  significant  improvement  of  the system performance when the proposed strategy is applied.

This paper presents the studies required for the design and construction of a versatile Half-Bridge converter. This converter can drive a wide variety of machines - from one to four phases. The converter was designed mainly to drive Variable Reluctance Machines in 6x4, 6x6, 8x6 and 12x8 topologies, working as both motor and generator. The versatility of the proposed converter is its main advantage, as in both academic and industrial applications, this feature can generate financial and production time savings. An analysis was carried out among the main converter topologies to justify the choice of the Half-Bridge topology followed by a project detailing of the chosen converter. For the design and construction of this converter, only commercially available devices were considered. To control the triggering keys, the Arduino platform was used due to its easy access and low cost. After the converter power circuit definition, the circuit for communication between the sensor (encoder), the controller (Arduino), and the switches (IGBT) is presented, and the project assembly is shown at the end.

Published: September 2020

This study aims to (1) Know the improvement in student learning outcomes in the drumset instrument class after applying the Fernando Martinez practice method; and (2) Knowing the obstacles that exist during the application of the Fernando Martinez (FM) practice method. The research method used is classroom action research (CAR) carried out in two cycles. The stages in this study include the planning, action, observation, and reflection stages. Data obtained include student learning outcomes, observations of student drumset practice activities obtained from videos and observation sheets, as well as the results of interviews. The results of the study in the first cycle showed that there was an increase in student learning outcomes, but the learning outcomes had not yet reached the indicators of learning achievement, namely the minimum score with a very good category (90-100). While the results of the research in the second cycle there is an increase in student learning outcomes that are significant when compared with before the application of the FM practice method and in first cycle. The obstacles faced when conducting research in the first and second cycles include; lack of motivation of students towards the tasks given, students have not been able to master the material well, because the FM method is new so students are not familiar. the stages of the FM practice method in first cycle have not been carried out correctly, the collection of tasks in the first cycle in this case the practice video was not collected on time.
