Published: July 2020

Internship is an undergraduate activity for gaining working experiences. Hence, it is expected that some universities convert it as an undergraduate course. In our university, registering internship topic is automated using a web-based portal; it takes tremendous effort if done manually. Nevertheless, according to our informal survey, existing portal suffers a lot of limitation, resulting user dissatisfaction. This paper presents a further development of such portal by following phases described in Application Lifecycle Management. According to three evaluation scenarios (black-box, small-group user, and large-group user testing), proposed portal works well and fits user need.

A System Dynamics Simulation to Estimate Roundabout Entry Capacity by Adopting Three Different Methods
Authors: N. Zehawi Raquim 
Published: July 2020

Many models were introduced to estimate the roundabout entry capacity from 1980s until now. In the United States, transportation agencies adopted three different models from 1994 until 2010. The Austroads, the UK, and the HCM 2010 methods. In this paper, these three methods were used to analyze the field traffic data of Al-Quds roundabout, located near Baqubah City, simultaneously by utilizing a system dynamics model. The collected data included turning movements, circulating flows, and field calculated entry capacities whenever possible during the observation period which lasted for 14 consecutive hours. A comparison is then conducted on the resulting entry capacities and their variation over time. The results showed that the calculated capacity according to Austroads method is the highest at all times while the UK method was always a little lower and the HCM 2010 method was always the least on all entries. The UK method capacity estimates were the closest to the field measured capacities for they returned the least RMSE on all entries. Field capacities showed some tendency towards the Austroads results in the north and south bound entries which carry about 66% of the total traffic. While, field capacities showed more proximity towards the HCM capacity results in the east and the west bound entries which carry 34% of the total traffic.

Abstract
Growing demands for building projects result from economic development. The building industry is dynamic and multifaceted. Efficient and effective practice of building production management (BPM) is required to successfully execute projects and achieve project goals upon completion as well as functionality aims for the lifespan of a building. This research aims to determine factors that influence the BPM practice in the Nigerian construction industry, particularly; during the project execution phase. A cross-sectional survey used; a questionnaire to identify 73 factors, which were grouped into 12 categories and assessed. A purposive sampling technique was used to identify 20 construction organisations specialising in building production management in Lagos, Nigeria. 114 questionnaires were distributed to the pool of stakeholders, which included 31 clients, 34 consultants and 49 contractors of current and past building production projects carried out by the selected firms in Lagos. The research used a selection of statistical tools for SPSS v.23, including the chi-square test, the Kruskal-Wallis test and Kendall's coefficient of concordance. The obtained result revealed the factors that mostly influence the BPM practice namely, architectural drawings, the construction programme document, the work breakdown structure, the adequacy of communication and coordination between the parties, the adequacy of raw materials and equipment, the availability of the competent team, the implementation of the safety management system, regular maintenance of project equipment, clear and timely inspections, the availability of funds as planned throughout the project duration, the availability of skilled personnel, and the aesthetics of the completed work. The research resulted in the development of the BPM implementation framework and recommendations for the improvement of the BPM practice in Nigeria.
Einstein-Elevator: A New Facility for Research from μg to 5 g
Authors: Lotz Christoph , Froböse Tobias , Wanner Alexander , Overmeyer Ludger , Ertmer Wolfgang 
Published: July 2020

Abstract
Increasing efforts to move into space have driven the need for new facilities that are capable of simulating weightlessness and other space gravity conditions on Earth. Simulation of weightlessness/microgravity (approximately 10−6
g) is conducted in different earthbound and flight-based facilities, often with poor availability. Other conditions such as lunar or Martian gravity with their partial Earth gravity/hypogravity cannot be performed at a large scale for scientific research on Earth. For multiple Earth gravity/hypergravity, simulation centrifuges are available, but they do not allow the possibility of abrupt acceleration changes. To support this wide range of conditions, a new technique is being developed to combine all of these requirements into a single drop tower facility. Currently under construction, the Einstein-Elevator of the Hannover Institute of Technology at the Leibniz Universität Hannover is an earthbound tool created for simulating micro-, hypo-, and hypergravity research with a high repetition rate. The facility will be capable of performing 100 experiments per day (8-h work shift), each creating 4 s of microgravity. For the first time, statistics can be applied in experiments under space gravity conditions at favorable costs and short mission times. The Einstein-Elevator offers room for large experiments with a diameter up to 1.7 m and a height up to 2 m as well as weights up to 1,000 kg. To perform larger experiments under different gravitational conditions, it was necessary to develop an innovative drive and guide concept. The Einstein-Elevator will be available for general research under different gravity conditions from 2018 onward.
Asylum Proceedings in the Czech Republic During the Migration Crisis
Authors: Černý Petr 
Published: July 2020

Abstract
The article deals with the fundamental problems that emerged on the territory of the Czech Republic during the implementation of the asylum procedure throughout the migration crisis in the years 2015 to 2019. Problematic issues related primarily to the detention of migrant asylum seekers were identified by studying the key decisions of national and international courts. The first problematic point was the amendment to the Asylum Act, which required the courts to discontinue proceedings on the review of detention orders after the foreign national was released from detention. Due to the conflict with EU law and the impossibility to claim damages for unlawful detention, this amendment was finally annulled by the Constitutional Court. The second problem was that the factual conditions for asylum seekers in the EU Member State where the asylum seeker was to be transferred for the purpose of processing his/her asylum application, were not examined. In this regard, the situation had since been rectified and the administrative authorities and courts of the Czech Republic already take this aspect into account when deciding whether an asylum seeker detained on the territory of the Czech Republic is to be transferred to the country where he/she applied for asylum. The most serious problem is so far incomplete transposition of the Procedures Directive, in particular Article 46 of the Procedures Directive, which requires from the court to review the decisions on asylum in full jurisdiction and could possibly grant asylum itself. However, this requirement does not correspond to the concept and system of administrative courts in the Czech Republic and would require a significant and costly change. The last issue identified was the poor implementation of the Dublin III Regulation, involving not setting serious risk of absconding of an asylum seeker as a precondition for his/her detention directly in the law.
Skeletal muscle mass by bioelectrical impedance analysis and calf circumference for sarcopenia diagnosis

Published: July 2020

Abstract
Skeletal muscle mass (SMM) plays an important role in health and physical performance. Its estimation is critical for the early detection of sarcopenia, a disease with high prevalence and high health costs. While multiple methods exist for estimating this body component, anthropometry and bioelectrical impedance analysis (BIA) are the most widely available in low- to middle-income countries. This study aimed to determine the correlation between muscle mass, estimated by anthropometry through measurement of calf circumference (CC) and skeletal mass index (SMI) by BIA. This was a cross-sectional and observational study that included 213 functional adults over 65 years of age living in the community. Measurements of height, weight, CC, and SMM estimated by BIA were made after the informed consent was signed. 124 women mean age 69.6 ± 3.1 years and 86 men mean age 69.5 ± 2.9 years had the complete data and were included in the analysis. A significant positive moderate correlation among CC and SMI measured by BIA was found (Pearson r= 0.57 and 0.60 for women and men respectively (p=0.0001)). A moderate significant correlation was found between the estimation of SMM by CC and by BIA. This suggests that CC could be used as a marker of sarcopenia for older adults in settings in lower-middle-income countries where no other methods of diagnosing muscle mass are available. Although the CC is not the unique parameter to the diagnosis of sarcopenia, it could be a useful procedure in the clinic to identify patients at risk of sarcopenia.

Authors: Michałek Marcin , Tabiś Aleksandra , Noszczyk-Nowak Agnieszka 
Published: July 2020

AbstractIntroductionAtrial fibrillation may potentially contribute to oxidative stress to a greater extent than chronic heart failure. The aim of the study was to compare the serum total antioxidant capacity and enzymatic antioxidant defence of dogs with chronic heart failure and atrial fibrillation with those of subjects with chronic heart failure and sinus rhythm and healthy controls.Material and MethodsA total of 33 dogs were divided into three groups: dogs with chronic heart failure and atrial fibrillation (CHF + AF; n = 12), chronic heart failure and sinus rhythm (CHF + SR; n = 9), and healthy controls (n = 12). Serum total antioxidant capacity (TAC), serum CuZn-superoxide dismutase (SOD) and catalase, and plasma glutathione peroxidase (GPx) activity were determined.ResultsSOD activity and serum TAC were significantly lower in the study groups than in control animals. Catalase activity was significantly higher and plasma GPx activity significantly lower in dogs with CHF + AF compared with the CHF + SR and control dogs.ConclusionThe results suggest that chronic heart failure in dogs significantly impacts the serum TAC and the antioxidant enzymatic defence, while plasma GPx activity is markedly lower in dogs with chronic heart failure and atrial fibrillation. The role of that imbalance needs further investigation.

Abstract
The internal combustion engines performance can be increase. The residual gases can be recovered through turbo charging systems because is an important reserve of exhaust gas energy, which can be capitalized. The turbo charging solution is one of the most popular technical solutions for increasing the energy performance of internal combustion engines. The solutions proposed for the theoretical and experimental research is the hybrid turbocharger. The hybrid turbocharger has a double function: to compress the fresh air and to generate electric energy for the vehicle. The compressed fresh air is compress by the rotor wheel of the compressor. The generator which produces the electrical energy is linearly coupled to the rotor on the compressor shaft outside zone. The electrical energy can be used for consumption of the military vehicles or can be stored in to the battery of the vehicle. The military vehicle must have a internal combustion engine or a hybrid engine equipped with a hybrid turbocharger. The article aim is to present the results of the hybrid turbocharger. The simulation was realised with the AMESim Software developed by Siemens. To simulate the exhaust gas energy was used a CIMAT test bed which can provides high pressure air.

Authors: Jerlăianu Marian , Petrişor Silviu Mihai , Bouleanu Iulian 
Published: July 2020

Abstract
In this paper, the authors want to highlight aspects related to the development, testing and use of an innovative technological product of the electric generator type with magneto, adapted for the production of heat and electricity. Its organology is based on a metal chassis to which is attached the heat engine and the generator with tensioner. The transmission of the rotational movement from the engine to the generator is done with the help of a V-belt. From a constructive point of view, the innovative aspect of the prototype is the adaptation of a moped-type electricity source, called here magneto, on a mobile generator structure that facilitates its independent and separate operation from the motors on which they are assembled. The heat engine has an installation attached to the section to exhaust the fumes resulting from the combustion of fuel. It accumulates heat that it releases into the outside environment. The tensioner allows the connection between the motor and the generator to be broken, allowing the motor to operate separately without generating electricity. The prototype has several constructive and functional advantages, such as: low mass, simple structure, energy efficiency and low operating noise.

Authors: Pogány Andrei-Mihai 
Published: July 2020

Abstract
Military actions generally unfold rapidly in different operational environments for which the commanding officer has assess the bearing capacity of the prestressed concrete bridges existing in the country’s road network. The bearing capacity is the maximum weight of the predetermined constitution convoy, which may safely circulate on the bridge, in stable conditions, considering the physical condition of the bridge. The paper shows that the bearing capacity will be assessed only through a technical analysis performed by an authorized expert together with a military engineer specialized in genius. This experts report will compare the initial condition of the bridge to the present one. The initial condition is based on the research of the execution design; the year of elaboration; the standard loadings at the moment; proprieties of the used building materials; execution modality, possible alterations occurring during execution as to the initial project. These data, together with the road traffic census, can be obtained from the company administrating the road network where the bridge is located. The current state to be assessed through analysis, calculation and static loading tests, showing if the capacity of the bridge can to support the increase of traffic military vehicle loading and reduction of the bearing capacity due to fatigue phenomena in the reinforcement. The paper proposes that authorities draw up and approve a standard concerning the verification periodicity of the bearing capacity in the existing prestressed concrete bridges.
Measurement of Geometric Features of Spherical Objects
Authors: Sotirov Branko , Tonev Danko 
Published: July 2020

Abstract
Spherical shaped objects are some of the most interesting and difficult to measure objects in dimensional metrology. Made of steel, alloys, ceramics, glass, rubber or plastics, they are important elements of precision bearings, pumps, valves, flow meters, medical, measuring, automotive, aerospace and other equipment, used for polishing, grinding, etc. Quality requirements, including their geometric accuracy, are high. A spherical object is defined geometrically by a centre, radius, and spherical spatial surface. There are no uniform rules and definitions for measuring these characteristics, and there is no standard definition of a form deviation. A number of solutions and publications are known to address the problem in practice, which, for the time being, do not allow a uniquely substantiated definition of the derived geometric elements and methods for their measurement. Full measurement of the deviation from sphericity, for example, is impossible. The question of the type of its associated element satisfying certain standard criteria remains open. The accuracy and reliability of measuring spherical objects is related to finding a reasonable solution to the outlined issues.

Abstract
Because of an increased prevalence of infections with resistant Gram-negative bacteria, finding optimal treatment regimens for these cases is one of the major healthcare concerns. Providencia is a Gram-negative bacteria belonging to the Enterobacteriaceae family. This article aims to describe an effective antibacterial regimen used for treating ventilator-associated pneumonia (VAP) with species of Providencia that are resistant to all antimicrobial classes. We present the case of a 74-year-old woman suffering from VAP caused by pandrug-resistant Providencia. The patient received high-dose intravenous meropenem (1 g every 12 h, infused over 4 h), intravenous amikacin (1,500 mg every 48 h) and nebulised amikacin (250 mg every 6 h). The dosages were calculated based on weight and renal function (GFR = 13.69 ml/min/1.73). After 23 days of treatment, following improvement in clinical signs (including fever), a drop in leucocytes counts, a higher than 80% reduction in procalcitonin levels (0.12), together with confirmed microbial eradication (negative sputum cultures), the antibacterial regimen was discontinued. In conclusion, when dealing with an infection with a pan-resistant microorganism, using combinations of antibiotics in high doses can be an option. These treatment regimens have the potential of overcoming in vitro resistance, leading to clinical improvement and microbial eradication.
Rare pulmonary tumours: a histological and radiological overview

Published: July 2020

Abstract
Adenocarcinoma, squamous cell carcinoma, and small cell carcinoma represent about 95% of lung tumours. However, the lung is the site of numerous types of tumours that may have an epithelial, mesenchymal, neuroendocrine, or lymphohematopoietic origin. With minor exceptions, both the clinical manifestations and the imaging characteristics are non-specific; many of the low-incidence tumours have common features with the high-incidence tumours. This article presents a group of low-incidence pulmonary tumours that pose multiple difficulties in terms of diagnosis due to non-specific symptomatology and non-specific imaging aspect. This article aims to correlate the histological data with imaging aspects to facilitate diagnostics. Because these tumours are rare and because they present in a variety of forms, problems may occur when establishing a diagnosis and trying to predict their behaviour. It is challenging to differentiate common lung tumours from rare ones based on clinical, radiological, or histological features. Only the presence of the imaging particularities, such as the location of the lesion, the association with certain patterns (appearance of ground glass, the “halo” sign, the presence of calcifications), and the histological/immunohisto-chemical profile can lead to the establishment of a correct diagnosis.
