The Effectiveness of Investing in Stock Exchange Markets in Central and Eastern European Countries with Regard to NYSE2‑LSE‑HKSE2. a Comparative Risk Analysis
Authors: Pera Jacek
Published: June 2019

The aim of this paper is to assess the effectiveness and risk in the stock exchange market in Central and Eastern Europe countries (CEE) in view of the largest stock exchanges: NYSE2‑LSE‑HKSE2. The implementation of this objective was based on an analysis of basic stock market indicators and a discussion of the investment effectiveness of the stock exchange and the risk and investment effectiveness analysis in the stock exchange market in CEE with regard to NYSE2‑LSE‑HKSE2 – assumptions, test method, tests results. The following working hypothesis was adopted in the analysis: Despite high vulnerability to investment risk, the stock exchanges in CEE, due to dynamic development, are improving their investment position with regard to global stock exchanges. The relative indices of stock market attractiveness and an autoregressive model for forecasting changes in the stock market index were used to verify this thesis. The results from the tests make it possible to state that the stock exchanges in CEE are constantly improving their position with regard to operational effectiveness and risk mitigation when compared to the largest global stock exchanges analysed, ambitiously striving to become significant financial centres within Europe and worldwide.
Human Capital and Intellectual Capital in Modern International Business –Based on Studies of the Strategies of Transnational Corporations
Authors: Rosińska‑Bukowska Magdalena
Published: June 2019

The main objective of the article is to discuss the direction of changes in the strategies of the most powerful transnational corporations as a result of adjustments to the new challenges created by the growing role of human capital in contemporary international business. Based on the concept of Grounded Theory Methodology, the author will indicate the main pillars of the strategy which can be considered effective for new challenges. The study has been divided into three parts. The first part discusses the most important theoretical issues concerning the place of human capital in the strategies of contemporary enterprises. In the second part, the author characterizes new trends in international transfers of human capital. In the next part, based on the research, the author discusses the impact of changes on the organizational and management system of enterprises – on the example of the most powerful transnational corporations. The studies have shown that all the most powerful transnational corporations notice the growing role of intellectual capital in contemporary business. The basis of corporations’ strategies is the emphasis put on the development of subsystems of intellectual capital, which refers to the activation of international transfers of human capital. In consequence, the strategies of the development of the most powerful transnational corporations are based on three pillars: networking, orchestration, and coopetition, and they are based on the three subsystems of intellectual capital: organizational capital, innovations, and the institutional environment.
Kant Meets Cyberpunk
Authors: Schwitzgebel Eric
Published: June 2019

I defend a how-possibly argument for Kantian (or Kant*-ian) transcendental idealism, drawing on concepts from David Chalmers, Nick Bostrom, and the cyberpunk subgenre of science fiction. If we are artificial intelligences living in a virtual reality instantiated on a giant computer, then the fundamental structure of reality might be very different than we suppose. Indeed, since computation does not require spatial properties, spatiality might not be a feature of things as they are in themselves but instead only the way that things necessarily appear to us. It might seem unlikely that we are living in a virtual reality instantiated on a non-spatial computer. However, understanding this possibility can help us appreciate the merits of transcendental idealism in general, as well as transcendental idealism’s underappreciated skeptical consequences.
The inverted classroom in health care – learner in the focus of digital change.

Digitization demands specific professional skills to meet current and future requirements. Especially in health professions, stakeholder are faced with the challenge to keep up with technological developments and changes in working structures, learning and communication processes. In addition, there is a need to modernize qualification structures and to beter connect theory and practice. The Inverted Classroom Model (ICM) provides a promising conceptual framework to approach these tasks systematically and provides suitable starting points to be integrated into existing structures. The ICM swappes classic teaching and learning spaces and links them using digital media. Thus there is more space and time, to create, to learn independently and to cooperate. This article presents the development and implementation of an ICM for the training of speech therapists and further training of hygiene professionals, based on their demands. Thereby conditions of success are derived. For this purpose, the results from two evaluations are stated – a target group analysis (standardized questionnaire) and the testing of the technical and media pedagogical implementation (focus groups). The results of the standardized survey provided a heterogeneous picture of the experiences in coping with digital media and clarified the need for practice-oriented and flexible learning opportunities. Based on this, a learning platform with appropriate communication and learning tools as well as learning content was developed. In focus groups, strengths and weaknesses of the implementation were identified, which led to technical and didactical adjustments. Due to the strong target group orientation, significant added value could be generated, which leads to higher acceptance, and is the prerequisite for sustainable integration. With the ICM it is possible to initiate active learning processes in both target groups and to establish a fruitful relationship between theoretical knowledge and practical experience.
How can problem-based learning be realised in blended learning format? Contribution to the HoGe conference 2018 „Digital learning and teaching“ / Wie kann problembasiertes Lernen im Blended-Learning-Format umgesetzt werden? Beitrag zur HoGe–Tagung 2018 „Digitales Lernen und Lehren“

Students can prepare themselves for the growing demands in the eHealth sector by using media-supported teaching settings during their training. Problem-based learning (PBL) is a learner-centered educational approach based on authentic problems. The 7 Jump Method is an established method for the implementation of PBL and for the theoretical treatment of problems in class. PBL is subject to the danger of „understeering the learning process” (Müller Werder, 2013). E-learning can make process control more eficient and structure it beter through role-specific templates. Using the example of a course of study in nursing at the Höhere Fachschule in Switzerland, the first possibilities for implementation in the health care professions are pointed out and critically discussed. The present case study was intended to answer this question: How can problem-based learning be realised in blended format?
Determination of Free Doxycycline Concentrations in the Plasma and Milk of Sheep and in the Plasma of Rabbits by using the HPLC Method
Authors: Mileva Rositsa
Published: June 2019

A fast and sensitive HPLC method was validated in order to analyze doxycycline in plasma and milk of sheep and in plasma of rabbits. The samples were processed with trifluoroacetic acid (TFA). After the centrifugation step, a supernatant containing extracted doxycycline and internal standard oxytetracycline was injected into the HPLC system with PDA detection. The method showed linearity in the range of 0.125 - 2.5 µg/mL for ovine plasma, 0.125 – 5.0 µg/mL for ovine milk, and 0.125 – 1 µg/mL for rabbit plasma. The inter-assay precision varied between 5.69 – 13.55 %. Values for intra-assay precision were between 0.62 – 8.67 %. Accuracy was higher than 90% in all of the tested concentrations in the three types of biological matrices. The mean extraction recovery was higher than 90 % for all matrices. In order to handle only with free drug concentrations, microfiltration of standard solutions with low (0.25mg/mL), medium (0.5mg/mL) and high (1.0mg/mL) concentration was performed. A percentage for correction of the quantified doxycycline was calculated. The most significant adjustments should be made at the low concentrations. The correction for rabbit plasma is 24.63±5.03%, for ovine plasma is 20.10±8.01% and for milk–16.68±0.04 %. This method can be used for routine determination of doxycycline concentrations for pharmacokinetic studies and further dosage adjustment.
Synthesis and optical properties of CdSe/CdS core/shell nanocrystals
Authors: Gadalla A. , Abd El-Sadek M. S. , Hamood R.
Published: June 2019

This paper attempts to describe an effective method for producing a composite of quantum dots consisting of CdSe (core) with CdS (shell). This nanoparticles composite was synthesized from modified organometallic precursors. The sizes of the nanoparticles were estimated from X-ray diffraction data using Debye-Scherer formula and compared with high resolution electron microscopy (HRTEM) and optical spectra. The shape of CdSe/CdS NPs is nearly spherical and revels that the CdS shell with the thickness ~0.6 nm almost fully covers the CdSe core (higher contrast). Using UV-Vis spectroscopy, a systematic red shift in the absorption and emission spectra was observed after the deposition of CdS which confirms the shell growth over the CdSe core. In the CdSe/CdS core/shell structure, the holes are confined to the core, while the electrons are delocalized as a result of similar electron affinities of the core and the shell. The increased time of synthesis resulted in shell thickness increase. The observed properties of prepared CdSe/CdS QDs demonstrate the capability of the nanocomposite for using in the optoelectronics and photonics devices.
Salt and the Development of Human Settlements with Balnear and Climateric Potential within the Romanian Intra-Carpathian Space
Authors: Romanescu Gheorghe
Published: June 2019

Deposit salt in Romania has extremely important reserves, considered even inexhaustible at the current exploitation level. The biggest salt resources are found in the intra-Carpathian arch, represented by Transylvania and Maramures. Most sources of salt outcrops are disseminated on the edge of the Transylvania Depression, in the diapir folds formed following salt migration. The salt mines – Turda, Praid, Ocna Mures, Ocna Dej, Ocna Sibiu, Cojocna, Ocna Sugatag – represented an important source of incomes, reason for which important human settlements formed around them. All these localities have turned nowadays into balneal and climacteric resorts that fully use the beneficial effect of the atmosphere within galleries (Praid, Turda). The most important incomes from tourism are represented by the galleries of the mines of Turda (one of the 10 wonders of the modern world) and Praid. The balneal and climacteric resorts also developed around the salt lakes installed in the areas of collapsed mines: Sovata, Ocna Sibiu, Ocna Dej, Cojocna. The most well known human settlements and the most important balneal and climacteric resorts, implicitly, are disseminated on the external branch of the Transylvania Depression (Sovata, Praid, Ocna Mures, Baile Figa, Cojocna thermae, Ocna Dej, Ocna Sibiu) and of the Maramures Depression (Ocna Sugata, Costiui, Vad). The oldest mining exploitation is situated at Figa (county of Bistrita-Nasaud) was founded around the year AD 3000. From this point of view, it is one of the oldest mining exploitations on Earth. The existence of the world-important archaeological site can invigorate the development of the surrounding localities, but mostly of the city of Beclean.
Investigation of Water Loss from Pipes Located in Various Relief Features of Iaşi County
Authors: Chirica Ștefania , Luca Mihail , Lateș Iustina
Published: June 2019

Water losses are present in all water supply system pipes. Their parameters and value vary depending on the constructional and functional features of the pipes (diameter, material, pressure, embedding environment, location, position etc.). The phenomenon is present in all water supply systems networks in Romania as well as globally. The water supply pipes within the regional water supply system are located in areas with diversified relief, from plateaus and hills to plains. The studies and researches were carried out in the geographical placement area of the Timişeşti-Iaşi pipeline. The geographic area studied is enclosed in Siret and Prut hydrographic basins. The paper aims to establish a correlation between the detection methods of water leaks from pipes and the areal relief features in Iaşi County. At the same time, it is highlighted the impact of the variation of the geographical relief characteristics on the water loss management on different type of pipes.
The Impact of the Absence of Communication on the Success of Rehabilitation Projects of the Built Heritage: The Case of the Old City of Constantine

Published: June 2019

Since the 1960s of the 20th century, research on the success of projects have been updated and are increasing in cyclical projects (event-centered projects) which appear regularly in excess of budget, or even sometimes incomplete when the event or subject of their creation is over. Within this context, with the appointment of Constantine as the Arab Capital of Culture 2015, the Algerian Government has registered 76 rehabilitation projects for the old buildings of the city, under the guardianship of the Ministry of Culture. The last has designated the Office National de Gestion et d’Exploitation des Biens Culturels Protégés (OGEBCP) (National Office for the Management and Exploitation of Preserved Cultural Property) as a contracting authority assistant, given its considerable experience in building management in the city of Tlemcen, Capital of Islamic Culture in 2011. During our investigation, none of the selected projects has been completed, while the allocated budget has been entirely consumed. Why? Who is responsible for this failure? Our role is to investigate the weak links in these rehabilitation projects to avoid future similar failure. It seems like the success of a project depends on the behavior of the main actors responsible for it as well as a number of technical skills that seem difficult to bring together in a single individual. Therefore, we focus on the actors of the project. The process of conservation operations is a delicate one to conduct for the success of the project. The conditioning of shorter deadlines in full eventcentered projects is in fact one of the most difficult challenges. We propose to analyze the management of communication between the project actors assuming that, an inappropriate management could have negative impacts on the success

Abstract: Analysis of reinforced concrete frame with steel braces has been done to compare the behavior of the open frame structure with reinforced concrete structure with steel braces. Three models of 2D open frame structure with 3, 4 and 5 floors were made and analyzed in SAP2000 v17 with intermediate detailing according to Indonesian Codes for Seismic Load (SNI 1726: 2002). 3-span frame structure with a span length of 6 m and level height of 3,5 m were designed according to SNI 1726: 2002, and then re-analyzed with special detailing according to New Indonesian Codes for Seismic Load (SNI 1726: 2012). After that, it was added with braces as seismic retrofitting. Two types of braces (X and concentric inverted V) were used in this study and analyzed with conventional analysis and stage construction analysis according to their stages of implementation. From the analysis results, several structure components that analyzed according to SNI 1726:2012 provitions were experience over-stressed. After retrofitted with steel braces, those components fulfill strength provition according to SNI 2847:2013 about structural concrete regulations for buildings. In addition to that, displacements that occurs on braced frame are smaller than displacements of the open frame structure with ratio of 0.08, 0.12, and 0.18 for X-brace frames with 3,4, and 5 storey and 0.07, 0.11, and 0.16 for inverted-V brace. With staged construction analysis, displacements of  X-braced frame structure increased by 14.38%, 13.62%, and 9.98% from the conventional analysis results for structure with 3, 4,and 5 storey. For structure with inverted-V brace, displacements increased by 15.83%, 14.29%, and 10.09%.

Abstract: Research on the seismic response of in-filled frame structure has been done with in-filled frame model as full and partial shell elements. The wall is considered active until the maximum load on the full shell models, while the partial shell model using the gradual load with the strength of the wall is considered inactive if the stress of the wall exceeded the wall strength The 4 storey hotel building with full wall in x-direction and wall with opening in y-direction were modeled in SAP 2000 as 3D infilled-frame using full and partial shell element. In Mxy models, both wall were included in the model, while in My models, only the wall in y-direction included. Therefore, 4 models were obtained, there are full shell model MxyShPn and MyShPn and partial shell model MyShPar and MyShPar. In addition, 2 diagonal strut models MxyS and MyS  and an open frame model MOF were made as comparison. Prior to model 3D structure, validation models were created using test result condited by other as reference. For that purphose 5 2D models were created there are open frame model MOF, single strut model MST, multiple strut model MSG, full shell model MShPn and  partial shell model MShPar. From validation models, it is apparent that the MxyShPar model mimic the behavior of tested structure better than the other models. From the 3D models analysis result show that the displacement in x-direction of MxyShPn, MxyShPar, MxyS were 89%, 85%, 84% smaller than those of MOF, respectively inclusion of wall in the models, also reduce the internal forces and reduse the natural period of the sctructure.

Authors: Rocha Rodolfo V. , Al-Omran Mohammed , Hussain Mohamad A. , Lee Douglas S. , Forbes Thomas L. , Lindsay Thomas F. , Ouzounian Maral
Published: June 2019

Purpose: The positive predictive value (PPV) of endovascular and open thoracoabdominal aortic aneurysm (TAAA) repair coding was assessed in

Ontario health administrative databases.

Methods: Between 1 January 2006 and 31 March 2016, a random sample of 192 patients was identified using Canadian Classification of Health Intervention (CCI) procedure codes and Ontario Health Insurance Plan (OHIP) billing codes from administrative data. Blinded chart reviews were conducted at two cardiovascular centers to assess the level of agreement between the administrative records and the corresponding patients’ hospital charts. The PPV was calculated with 95% confidence intervals using hospital charts as the gold standard.

Results: The PPV for the single endovascular TAAA repair code, 1ID80GQNRN, was 0.90 (0.78, 0.97). A combination of all nine CCI open

TAAA repair codes was performed, with a PPV of 0.62 (0.47, 0.76). The combination of any one of the nine CCI codes AND the single OHIP code for open TAAA repair (R803) rendered a PPV of 0.98 (0.90, 1.00).

Conclusions: Endovascular TAAA repair may be identified using a single CCI code (1ID80GQNRN). Open TAAA repair may be identified using a combination of CCI and OHIP codes. Researchers may therefore use administrative data to conduct population-based studies of endovascular and open repair of TAAA.
Efficacy of milrinone and dobutamine in low cardiac output states: Systematic review and meta-analysis
Authors: Mathew Rebecca , Visintini Sarah M. , Ramirez F. Daniel , DiSanto Pietro , Simard Trevor , Labinaz Marino , Hibbert Benjamin M.
Published: June 2019

Purpose: Patients in cardiac intensive care units (ICU) are admitted with increasingly higher disease acuity and a larger burden of non-cardiac critical illness. Accordingly, positive inotropes are being used with increased frequency and little comparative data to support drug selection. We compared the effectiveness and safety of dobutamine and milrinone in low cardiac output states (LCOS) and/or cardiogenic shock (CS).

Methods: We performed a systematic review comparing dobutamine to milrinone on all-cause mortality, length of stay in the ICU (LOS-ICU), length of stay in hospital (LOS-H) and significant arrhythmias in hospitalized patients with LCOS and/or CS.

Results: We identified 11 studies that meet eligibility requirements and which were published between 2001 and 2016 and included 23,056 patients. Only one randomized clinical trial was identified, with the remaining studies comprising observational cohort studies. The primary outcome, all-cause mortality, trended towards a benefit with milrinone but did not meet pre-specified significance (OR 1.13, 95% CI 1.00-1.29, p=0.06). While LOS-ICU (mean difference -0.72, 95% CI -1.10- -0.34, p=0.0002) was shorter with dobutamine, there was no difference in LOS-H (mean difference -1.22, 95% CI -4.68 – 2.24, p=0.49). Significant arrhythmias, specifically symptomatic and/or requiring antiarrhythmic therapy, were no different between the groups (OR 1.78, 95% CI 0.85-3.76, p=0.13).

Conclusions: Currently available data comparing milrinone to dobutamine in patients requiring inotropic support is limited. Dobutamine may be associated with a shorter LOS in the ICU, with a worrisome signal of increased risk of allcause mortality. Randomized data are needed to guide inotrope selection in patients with LCOS and/or CS.
Effect of adrenalectomy on pulmonary edema resolution
Authors: Massé Chantal , Berthiaume Yves
Published: June 2019

Purpose: The capacity of the lung to clear edema fluid has been shown to be one of the factors that can influence the prognosis of cardiogenic and noncardiogenic pulmonary edema. Active Na+ transport across the alveolar epithelium is the main driving force involved in this physiological process. Since endogenous catecholamines are known to activate the sodium-dependent mechanism of alveolar edema clearance, the objective of the present study was to explore if adrenalectomy, which prevents the release of endogenous catecholamines and other hormones, such as corticosterone, into circulation, would affect edema resolution in a model of lung injury induced by thiourea.

Methods: A high-permeability pulmonary edema was induced in adult male Sprague-Dawley rats using a thiourea-induced pulmonary edema model. To determine if the release of adrenalin and corticosterone is essential for resolution of the thiourea-induced edema, we measured 1) the release of adrenalin and corticosterone in urine and 2) edema resolution in control animals and adrenalectomized animals.

Results: The administration of thiourea significantly increased the wet-to-dry ratio after four and eight hours. After 12 and 24 hours, the wet-to-dry ratio gradually returned to baseline. Although thiourea-induced pulmonary edema was associated with a significant increase in urine adrenalin and corticosterone, the absence of adrenalin and corticosterone response in adrenalectomized animals did not prevent the resolution of the edema.

Conclusions: These experiments demonstrated that resolution of thioureainduced pulmonary edema can occur in the absence of hormonal secretion by the adrenal glands.

To determine the priority of medical evacuation of victims, an improved Revised Trauma Score (RTS) scale with user-friendly software for Android mobile devices (smartphone, tablet) was used. In case of mass-causalty event and a shortage of specialized sanitary transport, those who needed urgent specialized medical care were transferred from an evacuation center via radial evacuation to specialized medical organizations subordinated to the Ministry of Defense, the Ministry of Health and the subjects of Russia.Conclusion. The feasibility of deploying an airfield evacuation center to eliminate the health effects of emergencies was determined by potential discrepancy between evacuation capacities of air transport and ambulances, on one hand, and the need to temporarily accommodate (including isolation) and provide emergency health care to victims.
The role of the syndrome of chronic adaptive overstrain in the pathogenesis of wound disease
Authors: Novitskii A. A. , Kobiashvili M. G.
Published: June 2019

Relevance. More than 13.2 million injuries are recorded every year in Russia. For example, in 2005–2015 the level of injuries among the population of Russia was 92 ‰. Severe and combined injuries can be complicated by traumatic disease, which often occurred in the military when conducting combat operations.Intention.To present the mechanism of chronic adaptive overstrain syndrome in the pathogenesis of wound disease.Methodology. Wound disease is a special case of a traumatic disease, with an open wound with disrupted integrity of the skin and adjacent internal organs due to traumatic factors. The basis of the material was the author’s research on the study of chronic adaptive overstrain syndrome in 2500 servicemen of the Soviet Army in combat operations in the Republic of Afghanistan in 1979–1989.Results and Discussion. In contrast to a traumatic disease of peacetime, wound disease in a war is accompanied by impaired functional reserves in the form of an adaptive (environmental-occupational) stress syndrome due to “disturbing” combat stress factors. The main manifestations of chronic adaptive overstrain syndrome in military personnel are decreased body resistance to banal infections; high infectious morbidity throughout the year, regardless of the season; the growth of areactive forms of infectious diseases against the background of allergization; chronic inflammatory and recurrent processes; low rates of wound and other injuries healing; high frequency of infectious complications in the treatment of wounds; a significant weakening of the bactericidal properties of the skin; frequent occurrence of reactive arthritis in diseases for which joint damage is not typical.Conclusion. Extreme military factors result in depletion of the functional and structural reserve of compensatory processes of the body, with a state of pre-disease and complicated wound healing. Thus, initial manifestations of chronic adaptive overstrain syndrome due to combat stress in soldiers should be corrected as soon as possible.

Published: June 2019

Abstract: In the current trend, human activities of production and activities have discharged a large amount of waste. This makes the pressure to handle environmental pollution increasing. Therefore, environmental services have become an important economic sub-sector of many countries including Vietnam. In Vietnam, as of 2017, have 3,769 enterprises operate in the field of environmental services. Of which, more than 80% are non-state enterprises, about 1% are FDI enterprises and the rest are state-owned enterprises. Enterprises mainly focus on services with high demand resulting from the requirements of the 2005 Law on Environmental Protection, such as designing, manufacturing, and building waste treatment systems; environmental monitoring and analysis; consulting, training, providing environmental information. This paper provides a general analysis of businesses operating in the environmental services industry, the situation of attracting FDI into the industry, pointing out the causes and shortcomings in the development of the industry and giving some discussions and recommendations for developing environmental services in Vietnam

Sustainable Development and Social, Ecological, and Economic Transformation in Vietnam: Insights for Policy
Authors: Spangenberg Joachim
Published: June 2019

Abstract: Vietnam is at crossroads: being a middle income country now, it has to deal with social, economic and environmental challenges better known from affluent countries, while still being in the transition from an agricultural to an industrial in a society transiting from rural to urban. At the same time, Vietnam has to prepare for the diverse impacts of climate change, a process beyond its control, by developing adaptation measures safeguarding the social and environmental basis of the society and economy. This requires strategic planning with a focus on enhancing the resilience of economy and society; supporting differentiation and diversity is a core element of this, in rural as much as in urban settings. Current policies need to be updated to accommodate both the value of diversity, and the long term perspective required to mitigate climate change impacts.

Published: June 2019

The aims of this study are to determine the activity concentration of naturally occurring radionuclides in soils and the extent of their exposure to the population. The radioactivity concentrations of 226Ra, 232Th and 40K in the surface layers (5‑30 cm depth) collected from Khammoune province, Laos, were 32.57 ± 3.35 Bq.kg-1, 41.10 ± 3.04 Bq.kg-1 and 295.07 ± 17.36 Bq.kg-1respectively. From activity concentration of 226Ra, 232Th and 40K, we derived the parameters using the assessment of the radiological hazard from exposure to these soil samples. The average absorbed dose rate of all measured samples is 52.02 ± 4.09 nGy.h-1, while the average annual effective dose in the outdoor due to gamma radioactivity is found to be 0.06 ± 0.005 mSv.y-1.The average values for radium equivalent activity, external and internal hazard indices were found to be 114.07 ± 4.70 Bq.kg-1, 0.31 and 0.39, respectively.

Published: June 2019

Abstract: Effect of K substitutions on structural and superconducting properties in Bi-Pb-Sr-Ca-Cu-O (BPSCCO) system has been investigated. Bulk Bi1.6Pb0.4Sr2-xKxCa2Cu3O10+d (where x = 0.00; 0.04; 0.08 and 0.1) samples were fabricated by using the solid-state reaction method. Structural properties of the samples were examined by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) measurement. All samples showed co-existence of  Bi-2223 and Bi-2212 superconducting phases. Interestingly, a formation of the Bi-2223 was decelerated and that of the Bi-2212 was accelerated with increasing K content (x). Superconducting properties of the samples were characterized by using temperature dependences of resistance and field dependences of magnetization data. Both onset and offset transition temperatures were found to decrease, those were correlated to the decreases in residual resistance ratio (RRR). The 65 K magnetization curves of K- substituted samples were enlarged in comparison with that of the pure one. Enlargements of the magnetization curves were possibly attributed to the appearance of additional point-like defects generated by substitutions of K into Sr site.

Published: June 2019

Abstract: This paper presents the design, fabrication and operation of a highly symmetrical two-axis capacitive sensor. The proposed sensor consists of five electrodes, including of an excitation electrode and two pairs of sensing electrodes with exactly the same dimensions, arranged at identified symmetrically locations on a 3D printed hollow sphere, which containing dielectric medium formed by the partly filled oil and the remaining air. The proposed sensor can measure the tilt angle about the x-axis and y-axis with symmetrical outputs. The proposed sensor is fabricated using a rapid prototyping technology and mounted on the surface of a printed circuit board (PCB) for mechanical packaging and signal processing. Experimental measurement results show that the sensor system can measure the tilt angle in both the x- and y-axis with sensitivity of 103 mV/degree and resolution of ±1 degree in the range of -30 degree to +30 degree. This sensor system can be used in many military and consumer applications.

Demonstration on Ferroelectric-gate Thin Film Transistor NAND-type Array with Disturbance-free Operation
Authors: Trinh Bui Nguyen Quoc
Published: June 2019

Abstract: A novel concept of NAND memory array has been proposed by using only ferroelectric-gate thin film transistors (FGTs), whose structure is constructed from a sol-gel ITO channel and a sol-gel stacked ferroelectric between Bi3.25La0.75Ti3O12 and PbZr0.52TiO0.48O3 (BLT/PZT) gate insulator. Interestingly, ferroelectric cells with a wide memory window of 3 V and a large on/off current ratio of 6 orders, have been successfully integrated in a NAND memory circuit. To protect data writing or reading from disturbance, ferroelectric transistor cells are directly used, instead of paraelectric transistor cells as usual. As a result, we have verified disturbance-free operation for data reading and writing, with a small loss of the memory state and a low power consumption, in principle.

Published: June 2019

Abstract : The saturated magnetization in 20% substituted La0.8R0.2(Fe0.88Si0.12)13 (R = Sm, Tb) magneto-caloric alloys is discussed in this work.  The measurements were taken up to 70 kOe (7 Tesla) to detect the saturation of magnetic moments. As reported recently [Mat. Trans. 59(7) (2018) 1068], these compounds show a large variation of magnetic entropies at low field variation (~ 1.5 T), which associate with the large relative cooling efficiency (RCP) of 52 (for Tb-doped) and 102 J/kg (for Sm-doped) even at low effective DH of ~ 15 kOe. We re-detected the effective range of field variation DH and recognized that the effective DH ~ 5 kOe which is much lower than the value of other magneto-caloric compounds and is excellent for application of Sm-doped compound in modern cooling devices.

We present a reliable method for the fabrication of fluid phase unsaturated bilayers which are readily self-assembled on charged self-assembled monolayer (SAM) surfaces producing high coverage floating supported bilayers where the membrane to surface distance could be controlled with nanometer precision. Vesicle fusion was used to deposit the bilayers onto anionic SAM coated surfaces. Upon assembly the bilayer to SAM solution interlayer thickness was 7-10 Å with evidence suggesting that this layer was present due to SAM hydration repulsion of the bilayer from the surface. This distance could be increased using low concentrations of salts which caused the interlayer thickness to enlarge to ~33 Å. Reducing the salt concentration resulted in a return to a shorter bilayer to surface distance. These accessible and controllable membrane models are well suited to a range of potential applications in biophysical studies, bio-sensors and Nano-technology.
