Consulting Solutions: Thriving in the Federal Government Industry
Authors: A Alexander Leroy , Laux Fabiano , A Polanco Abraham , Presnell Ellen , Rock Darren
Published: May 2020

Consulting Solutions Inc has spent the past 20 years serving the Federal Government. Consulting Solutions got its start as an 8(a) company in the DIA Mentor-Protégé program as a Protégé business delivering top notch IT & Mission Services. The company graduated from both the 8(a) program and the DIA Mentor-Protégé program, demonstrating an ability to bid and execute on large scale programs. Throughout the company's lifespan, Consulting Solutions had endured its fair share of government turbulence and federal budget fluctuations to remain a player in the federal marketplace. In 2018, following 20 years of sustained excellence, Consulting Solutions underwent an acquisition and sold to a new ownership group. Planning on continuing the legacy of unmatched customer delivery, the new Executive Directors are combining highly skilled personnel with state-of-the art commercial technology, focusing on providing innovative solutions to support the federal government for another 20 years. This case explores the various federal government agency nuances, rigid employee vetting processes, and stringent guidelines for competing and thriving in the federal government industry.
TEACHING STRATEGIES USED IN CIVIC EDUCATION LESSONS IN SECONDARY SCHOOLS IN ZAMBIA
Authors: Oliver Magasu , Gistered Muleya , Liberty Mweemba
Published: May 2020

This study sought to investigate the teaching strategies used in Civic Education lessons in secondary schools in Zambia. The study used a descriptive case study design and data was collected using interviews, Focus Group Discussions (FGDs) and observations. Purposive sampling procedure was used to target seventy-four participants. Data collected was analysed using themes that emerged from the literature review and objectives of the study. The main findings of the study were that teachers in secondary schools still used teacher-centred strategies in the teaching of Civic Education despite policy direction in the Zambia Education Curriculum of 2013. Lecture method was common most Civic Education lessons. A few who implemented reflective practice strategies in their lessons used debate, group discussions and brainstorming. Based on the findings, social sciences departments where Civic Education sits in secondary schools in Zambia should find mechanisms of observing reflective practice strategy in the teaching of Civic Education rather than just seeing lesson plans. The Ministry of General Education should take a deliberate move to provide workshops/short courses to Civic Education teachers on the importance and use of reflective practice strategy in Civic Education lessons. Further, Curriculum Development Centre (CDC) and Examination Council of Zambia (ECZ) should collaborate and re-design the Civic Education Syllabus and give it a practical project since the subject is practical in nature. There is need in future to assess the training of Civic Education teachers with regards to training for reflective practice strategy.

Authors: ULUTÜRK Mehmet , TİLKİ Tahir
Published: May 2020

In this study, as a result of azo coupling of diazonium salts prepared with various aromatic amines with 2-(4-methylphenyl)-1H-indole and 2-(4-chlorophenyl)-1H-indole compounds, a series of new hetarylazo indole dyes were synthesized. N-substituted indole derivatives were synthesized by alkylation of the prepared dyes with the isopropyl alcohol from the N-position by Mitsunobu reaction. The chemical structures of the synthesized compounds were determined by NMR, FT-IR, UV-vis, mass spectrometry and elemental analysis. In order to determine the photophysical properties of the dyes obtained, visible region absorption spectra were examined in solvents of different polarity. In addition, the behavior of acid and base addition on absorption maxima were examined in detail.

Bu çalışmada, TÜBİTAK Ulusal Gözlemevinde (TUG) devam etmekte olan ötegezegen araştırmasının bir parçası olarak HD 199719’un tayfsal çizgi ortaylarının (bisektör) değişimleri incelendi. Gözlemsel tayflara bir şablon tayf ile çapraz korelasyon fonksiyonları (CCF) uygulanarak, ortalama çizgi profilleri elde edildi. Bu profillerden çizgi ortayları belirlendi. Bu çizgi ortaylarını nicel olarak tanımlamak için çizgi ortay ölçütleri kullanıldı. Bu ölçütler ile çizgi profillerindeki hız alanları hesaplandı ve dikine hız ölçümleri arasındaki ilişki araştırıldı. Yıldızın doğası kaynaklı (bulgurlanma (granülasyon), zonklama (pulsasyon), manyetik etkinlik kaynaklı yüzey lekeleri ve manyetik çevrim gibi) etkileri araştırmak için çizgi ortayların yanı sıra, Hα ve H çizgilerinin eşdeğer genişlik ölçümleri de yapıldı. Yıldızın çizgi ortay hız ile dikine hız değerleri arasında bir korelasyon olmadığı görüldü. Çizgi ortay hız ölçümleri (BIS ve BVC) için yapılan dönem analizlerinde 4.88 ve 10.36 günlük dönemleri işaret eden pikler elde edildi. Hα’nın eşdeğer genişlik ölçümleri için uzun dönemli bir değişim olabileceği görülse de, benzer bir değişim H’nın eşdeğer genişlik ölçümlerinde elde edilmedi.

Mono-, di- and trinuclear complexes of Fe(III), Co(II), Ni(II), and Cu(II) ions with Bis-N,N'(salicylidene)-1,3-diaminopropane (LH2), Bis-N,N'(salicylidene)-2,2'-dimethyl-1,3-diaminopropane (LDMH2), N(salicylidene)-2-hydroxyaniline (SAP), and Tris-N,N',N''(salicylidene)-2,2',2''-aminoethylamine (Trensal) were prepared and ionized with 30-110 eV electrons in direct inlet (DI). Compounds with metal-oxygen covalent bonds were observed to give molecular peaks, whereas polynuclear complexes containing coordinative bonds did not have such peaks. It was concluded that the coordinative bonds were dissociated by electron impact (EI). The thermogravimetric analysis reveals that the molecular peak observed for the mononuclear complexes which are stable up to 300 °C is also the base peak. The peaks obtained for the di- and trinuclear complexes that decomposed at these temperatures could not be observed as a molecular signal. The resulting fragments were evaluated and compared with the literature data.

La memoria histórica: Camino de reconocimiento de la alteridad en el conflicto armado colombiano
Authors: Rojas Claros Armando , Gómez Quitián Juan Carlos
Published: May 2020

El presente informe de investigación muestra cómo la memoria histórica puede convertirse en un camino educativo para el fortalecimiento de la alteridad en los estudiantes del curso de lógica y psicología de la Universidad Católica de Colombia, quienes han sido víctimas o espectadores del conflicto armado colombiano. Los participantes del estudio fueron los estudiantes de primer semestre de psicología, pertenecientes a la Universidad Católica de Colombia, de la asignatura Psicología y lógica; dos de los alumnos fueron víctimas directas, los demás han sido espectadores del conflicto armado colombiano. La información obtenida se sometió a un análisis de contenido de acuerdo con las categorías deductivas: alteridad, conflicto armado y memoria histórica.

Los resultados presentan la invisibilización de la persona, ya que han sido víctimas del impacto dentro del conflicto armado colombiano, con unas características propias del conflicto, el olvido y el silencio en contra de la misma humanidad por medio de la violencia que ha deshumanizado y desvirtualizado al ser, llegando a ser calificados como aquellos que son Nadie.

Por otra parte, la vulneración de los derechos humanos hacia las víctimas, por parte del estado y los grupos armados al margen de la ley, es indispensable para la memoria histórica como proceso educativo que lleva al reconocimiento de las personas, como miembros activos de la sociedad.

Published: May 2020

The objective of this study was to
evaluate the use of the ultrasound on the determination of the thickness of
adhesion at the abomasopexy point in cows which had undergone one-step
laparoscopic abomasopexy. Ten Holstein cattle with left displaced abomasum
(LDA) were included in the study. Animals were treated with one-step
laparoscopic abomasopexy whilst standing. Postoperative ultrasonographic
examinations were carried out starting immediately after surgery (day 0), and on
days 28, 90 and 120 by using a 5 MHz transducer frequency and also a linear
transducer. The thickness of the adhesion was measured between the abdominal
wall and the abomasum. Ultrasonographic image revealed the area of fixation on
day 0 as a mild distorted subcutaneous tissue. Heterogeneous hypo-echoic
irregular-shaped mass (adhesion) was observed between the abomasum and
abdominal wall on days 28, 90 and 120. Average thickness significantly (p
<0.05) increased from day 0 to day 28, but tended to decrease afterwards. The
average thickness of adhesion at the abomasopexy point was recorded as 20.47,
22.82, 22.34 and 21.92 mm on days on 0, 28, 90 and 120, respectively.

            The
ultrasonographic examination can diagnose and measure the adhesions between the
abomasum and the abdominal wall. During the study period, the adhesion
formation was followed up to the 120th day, and in this period the
thickness of the adhesion tended to decrease. Long follow-up studies are
thought to be beneficial to determine the difference in adhesion thickness.

Authors: Skolzkov Anton
Published: May 2020

Social studies
show an increasing number of people with anxiety disorders and depression
around the world. Selected data on Russia confirm this trend. Despite the
overall improvement in the world economic situation in recent decades, the stress
level has not decreased. Freshmen are particularly vulnerable to stress. This
pilot study assesses the mindfulness training effectiveness, which was aimed at
maintaining mental and physical health of Russian students. Participants: 107
freshmen of the Psychology Department of the Ural Federal University named
after B.N. Yeltsin. The data collection was completed in November 2019.
Methods: A non-randomized controlled trial was conducted using
Mindfulness-based cognitive therapy (MBCT) program. Results: MBCT reduced
depression and increased subjective happiness among the first-year psychology students.
More frequent mindfulness meditation practice and the study of the theoretical
materials are associated with higher rates of positive results of the program. Conclusion:
MBCT can be an effective program in working with first-year students of the

Authors: Chen Li , Zhong Yuting , Sheng Guojun , Zou Lin
Published: May 2020

Koch’s postulates are classical medical standard followed by researchers all over the world to identify a new pathogen for an emerging infectious disease (EID). In this article, we put forward a new concept of Koch’s time for a new pathogen (KTNP), which stands for the time from the first case of attention of an EID to the first complete genome of the new pathogen in a public domain, to quantify the response of EIDs. Shortening KTNP expedites development of detection kits and/or devices world-wide. The KTNP of five EIDs occurred in this century are calculated respectively. The results demonstrated that KTNP is continuously shortening and Koch’s time for COVID-19 is 15 days.

Authors: Williams Stuart
Published: May 2020

During the COVID19 pandemic, various investigations have been conducted to determine if personal protective equipment, and specifically N95 masks, can be decontaminated for reuse when unused equipment is not available. One method under investigation that may be particularly adaptable in lower resource communities is the use of heat and humidity for the deactivation of SARS-CoV-2. Food-warming cabinets (a.k.a. holding cabinets) may reach applicable temperatures and thus the purpose of this study was to characterize the temperatures achieved in a typical food-warming cabinets that has been adapted for the deactivation of N95 masks. This manuscript provides a general description of how a food-warming cabinet operates and describes aspects that are important for heat deactivation including characterizing cyclical heating and temperature variations within the cabinet. The described experimental procedure could be used as a guide to characterize similar food-warming cabinets.
Personality Change Through Arts Education: A Review and Call for Further Research
Authors: Grosz Michael P. , Lemp Julia , Rammstedt Beatrice , Lechner Clemens M.
Published: May 2020

Education involving active engagement in the arts, herein called arts education, is often believed to foster the development of desirable personality traits and skills in children and adolescents. Yet, the impact of arts education on personality development has rarely been systematically investigated. In the current paper, we reviewed the literature on personality change through arts education. We identified 36 suitable experimental and quasi-experimental studies. Evidence from these studies tentatively suggest arts education programs can foster personality traits such as extraversion and conscientiousness but not self-esteem. Also, the effects of arts education appeared to be stronger in early and middle childhood than in preadolescence and early adolescence. However, the evidence for the effectiveness of arts education was very limited among the few included true experiments. Furthermore, the reviewed studies were heterogenous and subject to content-related, methodological and statistical limitations. Thus, the current evidence base is inconclusive as to the effects of arts education on personality development. By identifying potential effects of arts education and limitations of past research, our review serves as a call for more research and guidepost for future studies on arts education and personality change.
Critical Issues Related to Connectivity in South Asia
Authors: Chand Hari P.
Published: May 2020

This paper mainly deals with connectivity of Nepal with neighboring countries and beyond. Nepal entered into an agreement with India for a Raxaul – Kathmandu railway line survey last year. After rail connectivity is established with India, Nepal is expected to benefit through transport costs compared to existing road connectivity. Nepal also signed an MoU with India for the development of inland water ways during the last visit by Prime Minister KP Sharma Oli to India. This is expected to provide Nepal with greater opportunities of better connection with Indian ports to promote trade with her southern neighbor and beyond. Moreover, Nepal and Chinese governments have agreed to work together to construct a rail link between Kerung and Kathmandu. This should allow Indian and Chinese railways to link in Kathmandu although that may yet take some time. Similarly, if Nepal deals tactfully with India and Bangladesh to make the Kathmandu-Kakarvitta-Phulbari-Banglabandha corridor function smoothly, there is a high possibility of establishing China-Nepal-India-Bangladesh (CNIB) Economic Corridor in the future. This paper attempts to explain the critical geo-political issues and challenges in connectivity facing Nepal. This paper is based on secondary data and both the qualitative and quantitative methods have been adopted for analysis. The key point of arguments presented by the paper is that all South Asian countries need to come up with “Connectivity Diplomacy”, preferably on the Track 1.5 level.

Published: May 2020

The focus is on a peanut suspension in which starch is added and that exhibits specific mechanical characteristics relevant for food products. The mixture is composed of water, lipids, starch, and proteins. The process consists of blending together the different constituents, and the study changes the experimental conditions to tune the mechanical behavior of the mixture. The rheological properties (viscosity, indentation) and physical parameters such as color, dry extract, and particle size distribution were measured. The matrix behavior was studied after a centrifugation step necessary to determine stability of the emulsion, and for varying shearing durations. Short shearing duration induce a maximum of firmness, observed by measuring indentation resistance, and a maximum of spreadability, evaluated by shear rheometry. On the contrary, long shearing durations destabilize the matrix emulsion by increasing the oil separation capacity. This study observes structural changes in the rheological behavior of this analogue artificial cheese that correlates with the extent of shearing.
Rainout Shelter-Induced Water Deficit Negatively Impacts Peanut Yield and Quality in a Sub-Humid Environment
Authors: Balota M.
Published: May 2020

Water deficit significantly reduces yield potential of peanut (Arachis hypogaea L.) worldwide. Availability of drought tolerant cultivars is essential, but their selection is difficult, in particular in environments where rainfall is unpredictable. This study investigated the response of eleven peanut genotypes to three water regimes and was aimed to determine if use of rainout shelters is a reliable selection method for drought tolerance in a sub-humid environment with unpredictable rainfall pattern. Water regimes were achieved by covering the plots from mid-July to early Sep with the rainout shelters and irrigating the plots to pre-determined levels: well-watered (WW) regime received full irrigation of 40 mm weekly, moderate deficit (MD) 17 mm weekly, and severe deficit (SD) only 40 mm in one “survival” irrigation in late Aug. Results showed that MD and SD reduced yield and grade for all genotypes. Compared with WW, economic value of all genotypes was 24% less under MD and 68% less under SD. Small seeded runner cultivars, ‘Florida 07′ and ‘Georgia 06G', had higher yield and grade than Virginia-type cultivars under deficit irrigation, in particular under SD. Among the Virginia-type, ‘Sugg' had highest yields under SD but was out yielded by ‘Bailey' and ‘Phillips' under MD. ‘Wynne' and ‘Spain' are the largest seeded Virginia-type cultivars; they performed poorest for yield and grade. The relative proportion of oleic fatty acid (C18:1) was less under SD compared to WW; and linoleic fatty acid (C18:2) and total saturated oils were more, but intensities depended on the genotype. Finally, the rainout setting provided comparative results with real farm peanut production in the region; this is important for breeding programs in Virginia and Carolinas, where rainfall unpredictability does not allow for drought screening in an open field setting.
Late-season Forage Harvest Effects on Pod and Forage Components of Valencia Market Type Peanut

Agricultural productivity per unit of land is a global concern. Moreover, farmers seek to add value to their enterprises. Interest has increased in harvesting Valencia market type peanut (Arachis hypogaea L. subsp. fastigiata var. fastigiata) for forage in food production systems. Trials at two sites near Brownfield, TX, USA, in 2012 and 2013, evaluated forage harvest timing [18, 20, 21, and 22 weeks after planting, (WAP), the last of which was sun-cured in the field from digging until threshing] on forage yield and nutritive value and pod yield of Valencia market type. Producers can harvest hay with greater nutritive value than stover by cutting and baling earlier during the pod maturation phase (about 18 WAP) although pod yield would be significantly (P < 0.05) reduced (2280, 2470, 2880, and 3450 kg pods/ha when forage was harvested 18, 20, 21, and 22 WAP, respectively, SEM = 90). Additionally, forage organic matter (OM) yield declined with each harvest after 18 WAP (3450, 2900, 2670, and 2460 kg OM/ha for forage harvested 18, 20, 21, and 22 WAP, respectively, SEM = 70). Crude protein (CP) concentration decreased across harvest dates from 158 to 124 g/kg and fiber fractions increased. Forage harvest prior to digging is not a viable option to add value to Valencia market type production because of reduced pod yield, which is the more valuable component. Other studies using different market types in other environments with earlier and similar harvest timings yielded similar results.

Evaluation of the Effect of (S)-3,4-Dicarboxyphenylglycine as a Metabotropic Glutamate Receptors Subtype 8 Agonist on Thermal Nociception Following Central Neuropathic Pain
Authors: Hosseini Marjan , Parviz Mohsen , Shabanzadeh Alireza P. , Zamani Elham
Published: May 2020

Study Design: In this study, we decided to change the activity of periaqueductal gray (PAG)'s metabotropic glutamate receptors subtype 8 (mGluR8) by means of its specific agonist, (S)-3,4-dicarboxyphenylglycine (DCPG), and by knock downing it with mGluR8 siRNA. We then evaluated the changes in animal pain threshold levels in the face of painful thermal stimuli (thermal hyperalgesia).Purpose: Although several mechanisms have been examined for central neuropathic pain, researchers have so far failed to find the precise mechanism for the development and progression of this type of pain. Hyperalgesia is one of the most important complications of central neuropathic pain and there is not a consensus among researchers about the exact cause of this complication. In this study, we investigated the effect of activation of the PAG region mGluR8 on the threshold of pain response to thermal noxious stimulus in rats and measured mGluR8 expression.Overview of Literature: Spinal cord injury (SCI) produces an decrease in mGluR2/3 expression in the injured and vehicle-treated groups compared to normal levels, APDC and L-AP4 treated groups had higher expression levels of mGluR2/3. These findings suggesting that the level of mGluR expression after SCI may modulate nociceptive responses.Methods: Male Wistar rats were randomly assigned to five groups (n=10 per group). The clip compression injury model was used to induce chronic central neuropathic pain. Three weeks after SCI, DCPG, siRNA, or normal saline were administered to the intra-ventrolateral PAG region. Withdrawal threshold to the noxious thermal stimulus (e.g., heat hyperalgesia) was assessed through the tail-flick test. In order to assure involvement of this receptor, pain responses were compared with mice that received GRM8 siRNA.Results: We found that the mGluR8 agonist DCPG increased lead to an increased expression of mGluR8 in the PAG region. We also found that SCI can decrease the threshold of response to painful thermal stimuli; however, activation of mGluR8 with DCPG agonist did not significantly improve the tail-flick response.Conclusions: The results revealed that activation of mGluR8 in PAG is not capable of improving the thermal hyperalgesia threshold. Based on the decreased expression of mGluR8 after SCI induced by clip compression injury and its significant increase after treatment of siRNA against mGluR8, this method might still hold promise as an effective treatment of neuropathic pain. It can be concluded that increased expression of mGluR8 is due to the fact that DCPG prevents the death of neurons that express these receptors.

Study Design: Single-center retrospective study.Purpose: We aimed to explore the postoperative prognostic factors for spinal intramedullary ependymoma.Overview of Literature: Ependymoma (World Health Organization grade II) is the most frequent intramedullary spinal tumor and is treated by total resection. However, postoperative deterioration of motor function occasionally occurs.Methods: Eighty patients who underwent surgical resection at Keio University and Fujita Health University in Tokyo, Japan between 2003 and 2015 with more than 2 years of follow-up were enrolled. A good surgical result was defined as an improvement in the modified McCormick Scale score by one grade or more or having the same clinical grade as was observed preoperatively. Meanwhile, a poor result was defined as a reduction in the McCormick Scale score of one grade or more or remaining in grade IV or V at final follow-up. Univariate and multivariate logistic regression analyses of the following factors were performed in the two groups: sex, age, preoperative Visual Analog Scale (VAS), tumor location, the extent of tumor resection, hemosiderin caps, cavity length, and tumor length on magnetic resonance imaging.Results: At final follow-up, 15 patients were included in the poor results group and 65 in the good results group. In the univariate analysis, the factors related to poor results were as follows: higher age, preoperative McCormick Scale score severity, higher preoperative VAS, thoracic location, hemosiderin capped, and non-gross total resection (GTR). A multiple logistic regression analysis was conducted and showed that age, worse preoperative McCormick Scale score, and non-GTR were significant factors for poor prognosis.Conclusions: The independent risk factors for motor deterioration after ependymoma resection were age, worse preoperative McCormick Scale score, and non-GTR. Early surgery for patients with even mild neurological disorders could facilitate functional outcomes. These results may contribute to determining the optimal timing of surgery for spinal intramedullary ependymoma.
An initial-boundary value problem for Boltzmann’s non-stationary nonlinear one-dimensional four-moment system of equations

Published: May 2020

In this article, the set of boundary conditions is defined for first and boundary value problems for the second approximation of Boltzmann’s system of one-dimensional nonlinear moment equations and their logic. For the second approximation of Boltzmann’s one-dimensional non-stationary nonlinear moment equations, which satisfies the Maxwell-Auzhan boundary condition, the theorem for the first boundary problem is considered and by proving this theorem, it is proved that there are only solutions to the given problems. It is known that in many problems of gas dynamics there is no need to describe the complete state of the gas by the function of microscopic distribution of molecules. Therefore, it is better to look for an easier way to describe the gas using macroscopic gas – dynamic variables (density, hydrodynamic average velocity, temperature) are determined in this rotations by the moments of the microscopic distribution function of the molecules, the author faced with the problem of analyzing the different moments of the Boltzmann equation. By studying the moment equations, the author obtained some information about the function of the microscopic distribution of molecules and the convergence of the moment method.
