Authors: Vasilescu Gabriel , Dinu Florea , Kovacs Attila , Laszlo Robert , Miron Claudia
Published: July 2021

The identification and consideration of various potential hazards significantly reduce the accidents in the industrial locations where specific operations with explosive materials take place. The purpose of this study was to assess the effects generated by external explosions produced near an experimental steel frame building model. The novelty of the paper is the combination of experimental results on site with data from specialised databases of accidental explosions. These data were integrated using computer modelling to evaluate the risk associated with different hazardous situations (shockwave propagation, spreading of debris), and the effects on the location. The numerical simulations were performed using IMESAFR software, which is a quantitative risk assessment tool and can be used to calculate risk to personnel from commercial explosives facilities and operations. The results of the simulations were used to design the perimeter security within the site and the placement of the experimental model, considering the maximum expected blast charge. Considering the limited space available on site, the results of the simulations were very valuable and confirmed the tests that were already planned can be performed without any risk for personnel, nearby buildings and facilities.

Authors: Ilici Stefan , Gheorghiosu Edward , Rus Daniela , Jitea Ciprian
Published: July 2021

The technical-economic efficiency of rock extraction works depends significantly on the drilling and blasting works as well as the adjacent costs. The cost of the explosive is an important component in these and the generalization of the widespread use of the use of bulk explosives (ANFO) has generated a significant reduction in the cost. Making the explosive close to the place of use in fixed or semi-stationary installations on the quarry stage eliminates the costs related to storage or long-term storage, transport, escort, security. However, installations for the manufacture of ANFO type explosives must consistently produce a simple quality explosive mixture. The quality lies in the participation of the precursors as well as in the degree of homogenization, stability and a good behavior to external stimuli that can lead to sensibility to initiation stimuli or inhibition of sensitivity where the harmful influence of moisture in the raw material or environment must be emphasized. The paper presents tests and results obtained in recent years for such installations used by several companies in Romania performed under the supervision of INSEMEX specialists. These assessments were completed with the certification of explosives manufacturing facilities for the specified operating parameters as well as for explosives.

Published: July 2021

Accidents are unplanned occurrences that result in injuries, illness, death, and loss of property and/or production. While there is no way to completely eliminate accidents, there are certain plans, preparations, and actions that can be taken to reduce them. First aid is usually a critical part in the management of acute injuries and conditions. The rescuer is the first person with medical training to arrive at the scene of a medical incident and the purpose of his actions is to maintain vital functions, to prevent the occurrence of dangerous complications for the life and health of the victim, before the intervention of medical staff. Despite current concerns about infection with the new coronavirus 2019 (COVID-19), prevention of its spread and treatment, various lesions and conditions unrelated to this virus still occur. Prompt first aid can prevent an additional burden on the health system by taking care of simple ailments at the crime scene, rather than calling the ambulance system or transporting the victim to a hospital. This paper presents first aid elements in the context of the COVID-19 pandemic, highlighting the manoeuvres that will be performed minimizing the risk of infection with the SARS-CoV-2 pathogen.
Measurement of the occupational risk level specific to workplaces
Authors: Călămar Angelica-Nicoleta , Simion Sorin , Kovacs Marius , Simion Alexandru
Published: July 2021

Any workplace implies a greater or lesser number of occupational hazards, respectively workers are exposed to occupational risks, putting their health in danger. If we talk about industrial environments (construction, energy, metallurgy, textiles, wood, etc.), these hazards are found to a greater extent, often exceeding the allowable limit, but occupational pollutants such as dust in suspension and microclimate parameters can also be found in offices, whether they are open space or not. In this sense, the current paper reviews some workplaces and quantifies the level of risk to which workers are exposed to show and demonstrate the importance of occupational health prevention in order not to reach further measures, in time, when these occupational diseases occur. The research conducted led to the conclusion that the determined pollutants (dust, gas, microclimate) exceeded the maximum allowable concentration required by national legislation, both at workplaces in various technological flows and in offices. The high concentrations found in offices are caused by staff traffic, large number of employees, as well as the lack of natural ventilation.

Finite element method to solve engineering problems using ansys
Authors: Şimon-Marinică Adrian Bogdan , Vlasin Nicolae-Ioan , Manea Florin , Florea Gheorghe-Daniel
Published: July 2021

The Finite Element Analysis method, is a powerful computational technique for approximate solutions to a variety of real – world engineering problems having complex domains subjected to general boundary conditions. The method itself has become an essential step in the design or modelling of a physical phenomenon in various engineering disciplines. A physical phenomenon usually occurs in a continuum of matter (solid, liquid or gas) involving several field variables. The field variables vary from point to point, thus possessing an infinite number of solutions in the domain. The basis of finite volume method relies on the decomposition of the domain into a finite number of subdomains (elements) for which the systematic approximate solution is constructed by applying the variational or weighted residual methods. In effect, finite volume method reduces the problem to that of a finite number of unknowns by dividing the domain into elements and by expressing the unknown field variable in term of the assumed approximating functions within each element.

Authors: Lupu Diana-Andreea , Avram Lazăr
Published: July 2021

The current circumstances of exploitation of natural gas fields in the Transylvanian basin under the rehabilitation concept which aims to maximize the productivity of wells and implicitly increase recovery factors, justifies the assessment of new perspectives for further exploitation of Badenian formations, in which gas accumulations are classified as being tight gas reservoirs types. The concept of stimulating productivity using high pressures in the Transylvanian basin has remained under the significance of the research, therefore it is appropriate to resume analysis of identifying new production technology by integrating new geological data acquired and other geophysical investigations. The current paper presents through a case study the process of identifying a candidate well for stimulation based on the geological-technological considerations, and then, performing a technical-economical analysis to support the proposed program.

Authors: Toderaş Mihaela , Filatiev Mykhailo
Published: July 2021

In the case of Roşia Poieni open pit mine the level of +805 m was established as a daily operating limit; the division into benches was based on this level by dividing into horizontal slices with a thickness of 15 m, equal to the height of the bench. Thus, there were 27 benches in the Curmătura area and 23 benches in the Ruginiş area. The general slope angle was set at 35°, the angle for which the tailings volumes and implicitly the opening-up coefficient were calculated. The stability analysis was performed for individual bench, 2 benches system and the general slope of the quarry (consisting of 24 benches), using two methods (Fellenius and Janbu). A polygonal slip surface was also modelled; such potential landslide surfaces can appear in the slopes of the Roşia Poieni quarry due to the natural cracking systems of the massif but also due to the secondary cracking generated by the used drilling-blasting works (exploitation technology). The stability check was done by applying Hoek’s graphical-analytical method; the determined values for the safety factor satisfy the condition of being greater than 1.3. In these circumstances, no further measures are required to increase the stability reserve.

Authors: Antonovits Ábel Dániel , Molnár József
Published: July 2021

Underground coal mining was finished in the north-eastern region of Hungary after its operation of more than two centuries, as a result of economic, technical, environmental and political reasons. A fairly significant part of the reserve is still available to extract. With a different perspective of coal mining, considering different ways of utilization (such as coal chemistry, etc.) the extraction of the material can still be cost effective. In the past few years, several studies were conducted regarding the possible utilization of the available reserve. The properties of the coal are highly mutable, therefore, comprehensive knowledge about the geology is indispensable. Two and three-dimensional modelling of the coal seam is discussed in this paper, with the optimal coal face height, and the expected quality of mining products taken into consideration. Applying the method presented, the production can fulfil the desired properties, regarding to the utilization of the coal.

Published: July 2021

Evaluation of explosion-proof protected electrical equipment in scope of certification is extremely important considering the risk of explosion that has to be minimized in order to ensure life safety and health of workers and to prevent damaging of property and the environment, as well as free movement of goods when they meet the essential safety requirements at European level.

Most of the equipment operating in potentially explosive atmospheres is represented by electric motors, which in most situations act on various other elements (e.g. pumps, valves, fans etc.).

Even if electric motors for explosive atmospheres are designed and manufactured following some of the same principles as the ones used for other electric machinery, they have certain particularities related to their field of use.

Thus, a series of specific restrictions and tests are required to be considered in their case. The purpose of this paper is to present the importance of the specific tests for electric motors with type of protection increased safety „e” designed to be used in explosive atmosphere.

Published: July 2021

The main objective of actual energy policies around the world is the transition to renewable energy. EIA forecasts nearly 50% increase in world energy usage by 2050, which is hard to achieve using only renewable energy. For year 2019 the electricity production in EU relies mainly on conventional thermal (42.8 %) and nuclear energy sources (26.7%). The accelerated transition to electrical cars puts more pressure on energy producers. As a result, in order to match the ever-growing demand of electrical energy, the conventional thermal energy generation will play a key role, among them coal-based production. In order to meet the environmental goals and for sustainable production of electrical power, energy assessment of power production of coal-based power plants must be performed. The purpose of this paper is to perform an energy assessment of the electrical power production, focusing on a key component of this, the steam turbine. The performance characteristics of the turbine in condensing operation were determined. A proper efficiency of the turbine will have a significant impact on sustainable production of electricity.

Published: July 2021

Exoskeletons are companion devices that help a person to perform various daily activities. These can range from work to medical rehabilitation. The type of activity performed depend on the construction and control of the exoskeleton, so that some devices are for only one arm, others for both, can be driven by motors directly or through cables. Exoskeletons can be driven based on information received from position, force, speed sensors or by using EMG, EEG signals. Exoskeleton wearable devices began to appear around 1980, as an aid in physical work, in the handling of various heavy objects. Over time, they also covered the preventive-rehabilitation medical side, in order to reduce muscle pain or to restore specific movements, attenuated or even missing following accidents or diseases of the muscles. The paper presents an overview of the exoskeletons developed for the human arm.

A study on the VLC security at the physical layer for two indoor scenarios
Authors: Riurean Simona
Published: July 2021

The visible light communication (VLC) systems are generally considered secure since the light cannot penetrate through solid objects. However, both in the line of sight (LoS) scenarios as well as in non LoS scenarios with wide and strong optical signal, information security must be considered. The conventional information security technologies used for wireless communications based on radio frequency are not suitable to be applied straight for VLCs because of the limited hardware resources, especially for the optical receivers (oRx). In this paper, a study on the VLC security at the physical layer approach based on optical beamforming to achieve secure transmissions for indoor and underground scenarios is presented.

Authors: Popescu Sorin , Radu Mirela-Ancuţa , Dinescu Stela , Vladuca Iulian
Published: July 2021

Evaluating the possibility to store CO2 in salt mines is made complex because of the lack of necessary data and different mechanisms that act on different time scales. This analysis can be made using traditional methods of geographical survey, lab experiments and digital simulations. Storing of CO2 needs to be done in a stable geological area. The cavity must be thoroughly analysed for dimensions, depth, permeability and porosity. Based on studies made by the University of Petroşani some areas subject to collapse have been monitored using topography and sonic measurements with the aim to understand their possible evolution. Monitoring caverns and underground cavities is done using sonar. The sonar is a good instrument to manage a cavern, it increases its safety while it is being exploited and offers important data for the geomechanics model. CavInfo software package has been specially created to analyse and show individual caverns or systems of caverns. CavView II software allows for results of cavern sonar surveys to be displayed in a variety of ways, with the added possibility to compare surveys, analysis of caverns and export of data.
The development of PID temperature controllers based on FEM thermal analysis
Authors: Alexandru Tudor George , Pupaza Cristina
Published: July 2021

Nowadays, most of the electronic components that are deployed in industrial devices represent active heat sources that demand adequate cooling solutions to ensure their safe and reliable operation. Thermal design and the development of temperature controllers represent the two essential branches of the cooling system development process. Both workflows can be tackled with the support of Computer Aided Engineering software. In this regard, the parametric study of coolers based on Finite Element Method thermal analysis is widely discussed throughout the literature. Even so, the use of such simulation tools for further developing temperature controllers is only addressed from theoretical point of views. The present paper represents an approach for implementing PID controllers that are applicable to industrial electronic devices. Tuning of the gains is completed by using the Ziegler-Nichols heuristic method. The proposed approach replaces the physical system with simplified thermal modelling. The given concepts are verified by means of a simple experimental setup.

Published: July 2021

The study highlights the complete image of the characteristics regarding offshore areas, by taking into account the perspective to deploy new measures of fiscal transparency. The importance of such areas stems from the fact that world economies lose important sums of money, every year by default of taxes. This happens as a consequence of corporative international abuse of fiscal evasion and the relocation of the profit made by big companies. The sums resulted from erosion of national taxation bases, from fiscal evasion and fraud and other infringements connected with fiscal evasion (are often being transferred to offshore companies so that their illegal characteristics gets lost and after that to be reintroduced into the economic cycle. The main characteristics of these offshore centres is lack of transparency and cooperation with foreign authorities, fiscal and banking secrecy being considered the guarantee of the offshore areas, measurable variables, fleshes in indicators that reflect the secret degree for each state. Therefore, fighting against such practicies through offshore societies aims at enforcing some measures to enlarge transparency and for the regions do not cooperate there is no granting of fiscal deductibility for transactions that entail the transfer of sums to the respective regions.

Published: July 2021

The article describes the personality characteristics of future psychologists-practitioners, who may at the same time be constituents of their professiogram, among which communicative competence occupies an important place. The purpose of our research was to study the psychological and pedagogical correlates of communicative competence of future psychologists-practitioners through the analysis of its separate components, which are resources for building effective communications. Communicativeness is defined as a professional basic competence that includes the following elements: tolerance, intolerance, acceptance of oneself, acceptance of others, self-regulation of one’s own emotions and states, flexibility, contactability, understanding of client’s emotions. At the same time, communicativeness is explored as the basic competence of a psychologist-practitioner, which sets the client up for positive and productive interaction in the process of psychological help, which is not an innate skill, so it can be improved during both professional training and during life. The statistical significance of the selected psychological and pedagogical correlates and their psychological components is determined. The multidimensional correlation study showed significant positive and negative correlations between the studied indicators. The components of psychological and pedagogical correlates of communicative competence are analyzed and substantially explained: tolerance, intolerance, flexibility in the communicative process, contactability, communicative control, communicative abilities.

Selected microemulsions containing MLE were incorporated in chocolate products to enrich them. Their color properties including CIE L*, a*, b* parameters and whitening index (WI) along with DPPH radical scavenging activity were assessed during a period of 8 months. The antioxidant activity of microemulsions depended on the oil phase used, while it was unaffected by the concentration of MLE. Samples prepared with soybean oil as oil phase containing MLE presented the highest radical inhibition percentage (I% = 26.8–27.8%). Coconut microemulsions were finally incorporated at 2 and 4% w/w concentration into chocolate products, as coconut oil is a known cocoa butter substitute. Although the incorporation of MLE microemulsions did not affect the color properties of most of the chocolates, enriched products did not exhibit superior antioxidant activity compared to control samples.

Die vollständige und reproduzierbare Erfassung und Dokumentation endoskopischer Befunde ist als Grundlage der Behandlung von Patienten mit chronisch entzündlichen Darmerkrankungen wie Morbus Crohn und Colitis ulcerosa von entscheidender Bedeutung. Diese Befunde sind zum einen Grundlage therapeutischer Entscheidungen und zum anderen ein unverzichtbarer Parameter der Bewertung des Ansprechens auf eine Behandlung. Endoskopische Befunde sollten daher nach standardisierten Kriterien erstellt werden, um eine Vergleichbarkeit der Befunde unterschiedlicher Untersucher wie auch die valide Erfassung von Veränderungen im zeitlichen Verlauf der Erkrankung zu gewährleisten. Vor diesem Hintergrund haben 15 Mitglieder der AG Bildgebung des Kompetenznetzes Darmerkrankungen ein Positionspapier erarbeitet, in dem eine Befundstruktur für die Dokumentation endoskopischer Untersuchungen entworfen wird. Die Empfehlungen adressieren neben den formalen Angaben zu jeder Untersuchung insbesondere eine Vielzahl von Attributen akuter und chronisch entzündlicher mukosaler Veränderungen sowie endoskopisch detektierbarer Komplikationen, die detailliert erläutert und anhand charakteristischer Abbildungen illustriert werden. Zudem werden häufiger verwendete endoskopische Aktivitätsindizes vorgestellt, und ihre Nutzung im klinischen Alltag wird diskutiert.

We conducted this meta-analysis to assess the effects of sodium valproate (VPA)
monotherapy on blood liver enzymes in patients with epilepsy. PubMed, Web of
Science, EBSCO, Cochrane Library, Wanfang, China national knowledge
infrastructure databases were searched. Nine studies were included. Results
showed: (1) The overall SMD for blood AST, ALT, and GGT levels of VPA
monotherapy group versus control group were 0.70 (95% CI=0.31 to
1.09, Z=3.52, p=0.0004), 0.47 (95%
CI=− 0.01 to 0.95, Z=1.91, p=0.06), 0.44
(95% CI=0.29 to 0.60, Z=5.55, p<0.00001),
respectively. (2) In subgroup meta-analysis, increased blood AST and GGT levels
were observed in epileptic minors (AST: total SMD=0.85, 95%
CI=0.40 to 1.30, Z=3.69, p=0.0002; GGT: total
SMD=0.46, 95% CI=0.29 to 0.63, Z=5.25,
p<0.00001). Elevated blood ALT level was observed in Asian patients
receiving VPA monotherapy (total SMD=0.70, 95% CI=0.51
to 0.90, Z=7.01, p<0.00001), and the early stage of VPA
monotherapy (total SMD=0.93, 95% CI=0.57 to 1.29,
Z=5.09, p<0.00001). Overall, our results indicated that blood
AST and GGT were significantly increased in epileptic minors receiving VPA
monotherapy. The elevation of blood ALT was observed in Asian patients and the
early stage of VPA monotherapy. However, due to the small number of included
studies, our results should be considered with caution.
Effect of Lisinopril and Verapamil on Angiopoietin 2 and Endostatin
in Hypertensive Diabetic Patients with Nephropathy: A Randomized
Trial

Angiogenesis is a multistep process implicated in the pathophysiology and
progression of diabetic nephropathy (DN). Angiotensin-converting enzyme
inhibitors (ACEI) and calcium channel blockers (CCB) have an important role in
DN. We performed a randomized-controlled trial of lisinopril alone (an ACEI) or
in combination with verapamil (a CCB) as a therapy for DN in type 2 diabetes
mellitus (T2DM) patients with hypertension (HTN) and urinary albumin creatinine
ratio (UACR) (30–300 mg/g) also to evaluate their effect
on UACR, the angiogenic proteins: Angiopoietin 2 (Ang-2) and Endostatin (EST).
Forty T2DM patients with microalbuminuria, aged 45–65 years were
included. Patients were randomly assigned into group 1 receiving oral lisinopril
and group 2 receiving oral lisinopril and verapamil once daily. After 3 months
follow-up fasting blood glucose (FPG), HbA1c, lipid profile, UACR, serum urea
and creatinine levels were assessed. EST and Ang-2 were measured using ELISA
technique. Baseline Ang-2 and EST levels were elevated in both groups compared
with controls (p<0.001). After follow-up, group 2 had significantly
decreased FPG, HbA1c, UACR, EST and Ang-2 compared with their baseline levels
(p<0.001 for all comparisons) and with group 1 (p<0.001). No
adverse reactions were reported. Baseline EST and Ang-2 were positively
correlated to UACR (r=0.753, p<0.001) (r=0.685,
p<0.001). Lisinopril/verapamil combination enhanced glycemic
control and kidney function via diminishing EST and Ang-2. This combination can
be considered as a safe and effective approach for early stage nephropathy
therapy in T2DM.
Das „Collaborative Assessment and Management of Suicidality“ (CAMS) – Eine wirksame (Kurz-) Intervention zur Behandlung von suizidalen Patienten

Das „Collaborative Assessment and Management of Suicidality“ (CAMS) ist einer von mehreren Interventionsansätzen zur Behandlung von suizidalen Patienten und Patientinnen und wurde weltweit seit 3 Jahrzehnten untersucht und weiterentwickelt. Das CAMS ist auf die Etablierung einer tragenden therapeutischen Beziehung auf Augenhöhe zu einer suizidalen Person ausgerichtet. Der Patient wird aktiv an der Einschätzung seines Suizidrisikos beteiligt und zum „Mitverfasser“ seines eigenen suizidspezifischen Behandlungsplans. Das konkrete therapeutische Vorgehen wird durch ein vielseitig anwendbares Instrument, die sogenannte Suizidstatusform (SSF), strukturiert und geleitet. Das CAMS kann von verschiedenen therapeutischen Berufsgruppen sowie bei Patienten und Patientinnen mit unterschiedlichen Diagnosen angewandt werden. Die Wirksamkeit im Hinblick auf eine Verringerung von Suizidgedanken, der allgemeinen psychischen Belastung und Depressivität sowie auf eine Zunahme von Hoffnung und Zuversicht ist mittlerweile empirisch gut belegt.
