Ng INFLUENCE OF COMPOSITION AND MICROSTRUCTURE ON THE FEATURES OF MECHANICAL PROPERTIES OF Co-Cr-Fe-Mn-Ni HIGH ENTROPY ALLOYS

The structure and mechanical properties of high-entropy CoCrFeMnNi (equiatomic) and Co20Cr26Fe20Mn20Ni14 alloys, which differ significantly in the stacking-fault energy, are studied. The structure of the alloys was investigated in three states – as-cast, after homogenizing annealing at T = 1000 °C for 24h and after annealing at T = 850 °C. It was found that in the cast state and after homogenizing annealing at 1000 °C both alloys are single-phase solid solutions with a FCC lattice. Annealing at 850 °C preserves the single-phase state in the equiatomic CoCrFeMnNi alloy, but leads to the appearance of a σ-phase in the Co20Cr26Fe20Mn20Ni14 alloy. The mechanical properties of these alloys were studied in a single-phase state by uniaxial compression tests and hardness measurements. It was discovered, that both alloys in a single-phase state had high plasticity and tendency to force strain hardening. The behavior of hardening coefficients in the area of true strains e = 0.05 – 0.17 vary considerably. This may be due to a significant difference in the stacking-fault energy of the investigated alloys. As a result, in Co20Cr26Fe20Mn20Ni14 alloy along with dislocation deformation mechanism there is a high probability of implementation the twinning mechanism.
EXTENSION OF EPANET FOR PRESSURE DRIVEN DEMAND MODELING IN WATER DISTRIBUTION SYSTEM

The use of mathematical models for simulating the physical behavior of water distribution systems becomes standard engineering tools of water utilities for applications such as design, calibration, rehabilitation and operation. Currently, there are several hydraulic simulation models and most of them are based on demand driven analysis (DDA). Recently, a number of studies have highlighted some of the limitations of demand driven analysis leading to remarks that such models may be inadequate when abnormal conditions are considered. In fact, demand flowrates are not only functions of time, since the node outflows occur via orifices (e.g. open taps or valves) and are thus dependent on the pressure in the system. Analysis that incorporates the relationship between demand and pressure are called pressure driven analysis (PDA). In this framework, functions assume fixed demand above a given critical pressure, zero demand below a given minimum pressure and some relationship between pressure and demand for intermediate pressures. In this paper, the authors describe an extension of the Epanet by OOTEN toolkit to directly include pressure driven demand modeling. The data structures and algorithms within Epanet source code are modified to adequate PDA modeling. To demonstrate the capability of PDA model manages the insufficiency of nodal pressure, failure conditions are assumed (fire flow). Results show that PDA can be more effective for simulating abnormal conditions than DDA. Finally, concluding remarks are presented.
'Validity and reliability of 'Barriers Scale' in utilization of research results by nurses' -

'Evidence-based nursing applications are an important factor in increasing the quality of care. However, studies have shown that nurses do not use research results adequately and they do not have adequate information about evidencebased nursing. The aim of this study was to carry out a validity and reliability study of the 'Barriers Scale' used to determine the barriers and facilitating factors related to applying the results of nursing studies. The study was carried out with a total of 631 nurses from 9 hospitals belonging to two different institutions in Ankara between September 1 and 30, 2004. Of all the nurses, 88.7% did not participate in any study and 70.0% did not participate in any scientific activity before. The general internal consistency Cronbachα coefficient of the scale was 0.87 and the scale was accepted as reliable. The most important barriers to the nurses' use of study results were not seeing enough authority in themselves to change current applications, not having enough time to read studies and not having adequate resources for nursing applications.

POSSIBLE TWIN kHz QUASI-PERIODIC OSCILLATIONS IN THE ACCRETING MILLISECOND X-RAY PULSAR IGR J17511–3057

We report on the aperiodic X-ray timing and color behavior of the accreting millisecond X-ray pulsar (AMXP) IGR J17511–3057, using all the pointed observations obtained with the Rossi X-Ray Timing Explorer Proportional Counter Array since the source's discovery on 2009 September 12. The source can be classified as an atoll source on the basis of the color and timing characteristics. It was in the hard state during the entire outburst. In the beginning and at the end of the outburst, the source exhibited what appear to be twin kHz quasi-periodic oscillations (QPOs). The separation Δν between the twin QPOs is ∼120 Hz. Contrary to expectations for slow rotators, instead of being close to the 244.8 Hz spin frequency, it is close to half the spin frequency. However, identification of the QPOs is not certain as the source does not fit perfectly in the existing scheme of correlations of aperiodic variability frequencies seen in neutron star low-mass X-ray binaries (NS LMXBs), nor can a single shift factor make it fit as has been reported for other AMXPs. These results indicate that IGR J17511–3057 is a unique source differing from other AMXPs and could play a key role in advancing our understanding of not only AMXPs, but also of NS LMXBs in general.
Role of methylglyoxal in the pathogenesis of hypertension

Methylglyoxal (MG), a metabolite of glucose, causes non-enzymatic glycation of proteins to form irreversible advanced glycation end products (AGEs). Increased MG production, which in turn gives rise to AGEs, has been linked to the development of complications in diabetes. However, the role of MG and AGEs in hypertension has not been investigated widely. The previous study from our laboratory showed that the cellular levels of MG and MG-induced AGE formation are significantly higher in cultured aortic smooth muscle cells from spontaneously hypertensive rats (SHR) than those from normotensive Wistar-Kyoto rats (WKY). Using immunofluorescence staining with specific monoclonal antibodies against MG-induced AGEs, the present studies show a strong association of MG and its AGE products (N-carboxyethyl-lysine and N-carboxymethyl-lysine) with hypertension in SHR. The blood pressure of SHR was not different from that of WKY rats at 5 wks of age. From 8 wks onwards, blood pressure was significantly elevated compared to age-matched WKY rats. Importantly, this increase in blood pressure coincided with an elevated MG level in plasma and aorta of SHR in an age-dependent fashion compared to age-matched WKY rats, although no difference was observed in blood glucose levels between these two strains. Our data showed an increased MG level in plasma and aorta, but not in kidney or heart, in SHR at an early age of 8 wks, suggesting, in addition to diabetes/hyperglycemic or hyperlipidemic conditions, the accumulation of MG in blood vessel walls plays an
IdeologicalprofilesofUSadultsandtheir support for youth mentoring

Funding information Division of Graduate Education, Grant/Award Number: 1356104; MENTOR: The National Mentoring Partnership Abstract Little is known about the influence of political ideology and religiosity on adults’ support for youth mentoring as a strategy to address social problems. This study used latent class analysis in a large, national sample of US adults to identify underlying ideological profiles associated with support for mentoring programs. Three latent classes emerged. The attitudes of two classes, Classic Conservatives and Progressives, were consistent with traditional political conservatism and liberalism; the latter endorsed higher support for the theory of mentoring and government spending on mentoring programs. Members of the third class, Religious Outsiders, were highly religious, self‐identified as very conservative, and were highly supportive of the theory of mentoring and the use of government funds on mentoring programs. Ad hoc analyses revealed that Religious Outsiders were the most likely to actually participate in mentoring activities. These findings suggest that support for mentoring, while not universal, crosses traditional political lines.
Optimization of kNN Classifier Using Hybrid Preprocessing Model for Handling Imbalanced Data

The conventional k Nearest Neighbor (kNN) classifier has many challenges when dealing with problems caused by imbalanced data sets. The classifiers are usually designed to improve accuracy by reducing the errors and therefore, they do not rely on class distribution or proportion or balance of classes. So for handling imbalanced data issues data preprocessing techniques such as sampling methods are widely used. One of them is Synthetic Minority Over-sampling Technique SMOTE. SMOTE with kNN was found to be deficient when it came to handling imbalanced data specifically in terms of accuracy. In this paper, we have proposed a preprocessing model for imbalanced datasets before it can be sent to the classifier. The proposed model is a hybridization of three preprocessing techniques; they are SMOTE, Resample technique and Attribute Selection technique combined to form SMOTE Resample Attribute Selection (SRAS). To see the performance of the proposed preprocessing hybrid model SRAS working with kNN classifier, we have taken several imbalanced datasets. These datasets have been tested and compared on standard kNN, SMOTE with kNN and SRAS with kNN. The proposed preprocessing model SRAS gave superior and enhanced outcomes for kNN classifier in terms of accuracy, recall, F Measure and AUC (area under the curve).
Echocardiography in Hypertension: A Review

Echocardiographic (echo) studies of left ventricular (LV) structure and function in patients with primary hypertension have been discussed in Part I of this review. ' The second part is an evaluation of echo studies of cardiac structural and functional changes associated with antihypertensive interventions. Clinical echo studies of effects of antihypertensive interventions have assessed changes of LV wall mass, cross-sectional area, or wall thickness, systolic wall stress and systolic LV function (including circumferential fiber shortening [ (V,,)], fractional shortening [ (FS)], and ejection fraction). M-mode echocardiographic techniques (as opposed to two-dimensional techniques) have been used in most of these studies. The validity and reproducibility of the techniques for assessing these parameters have been discussed in Part I. Clinical studies of regression of LV hypertrophy were stimulated by findings in hypertensive rat models showing variable effects of antihypertensive agents on regression of LV wall mass, despite significant decreases in systemic pressure. An important consideration in such studies is change (or lack of change) in LV wall stress with reduction in systemic arterial pressure. Possibilities include: (1) LV wall mass may decrease proportionately, in which case wall stress will remain the same; (2) LV wall mass may decrease to a larger degree than sys-
Kinship Care: Fostering Effective Family and Friends Placements

Family and kinship care has a long history. It dates from times when children or young people were taken in to extended family networks or placed with relatives when birth parents or primary carers were unable, for whatever reasons, to provide them a home and developmental opportunities. Indigenous cultures – such as found amongst Maori peoples in New Zealand – commonly arranged for the eldest child to be placed with an elder aunt, uncle or grandparent who thus passed on important cultural learning and practices to the next generation. In South Africa, family and kinship care innovations are being used to support family groups where parents or primary carers have died because of HIV-AIDS. Family and kinship care has always played a significant part in child welfare systems operating everywhere.
CHOLECALCIFEROL ATTENUATES INDUCED PARKINSON ’ S LIKE-DISEASE VARIATION AND CELLULAR MORPHOLOGY OF STRIATUM AND SUBSTANTIAL NIGRA

Parkinson’s disease is the commonest motor neurodegenerative disorder which affects the dopaminergic neurons and causes significant loss of dopamine. 1-methyl 4-phenyl-1,2,3,6tetrahydropyridine (MPTP) is a selective neurotoxin in the nigrostriatal pathway leading to this motor disorder. Cholecalciferol (Vitamin D3) has been described as an active neurosteriod with antioxidant properties ubiquitously present in the brain. The study hypothesized that stimulation of vitamin D receptor by cholecalciferol could reduce autophagic cell death and degeneration following a state of drug induced parkinsonism in mice. The aim of the research was to observe the cytoarchitectural, histochemical, neurobehavioural and immunohistochemical effects of cholecalciferol on striatum and substantia nigra in mice model of MPTP-induced Parkinson’s disease. Fifty adult male C57BL/6J mice weighing about 25-35g were randomly selected and assigned into 5 groups for this study. The mice were then subjected to neurobehavioural, neurochemical and neuropathological evaluations. The results obtained showed a significant reduction (*p<0.05) in the estimated markers of oxidative stress with high dose of vitamin D3 following MPTP induction. There was also statistical significant reduction (**p<0.01, ***p<0.001) in the expression of GFAP-immuno-positive cells in the substantia nigra of the experimental mice when compared with the control group. It can be inferred that the administration of Vitamin D3 was associated with significant attenuation of focal effects linked with MPTP in mice model of Parkinson’s Disease.
Performance of some advanced spring wheat lines under optimum and late sown conditions in different regions of Bangladesh

Eleven advanced lines of spring wheat along with check varieties BARI Gom 21, BARI Gom 26 and BARI Gom 32 were evaluated at Bangladesh Wheat and Maize Research Institute (BWMRI), Dinajpur; Regional Wheat Research Center (RWRC) Gazipur; Regional Agricultural Research Station (RARS), Bangladesh Agricultural Research Institute (BARI), Jashore; RWRC, Rajshahi and RARS, BARI, Jamalpur in randomized complete block design (RCBD) with three replications during, November, 2017 to March, 2018. The trial was conducted under irrigated timely sown (ITS) and irrigated late sown (ILS) conditions. The genotypes were evaluated for yield and yield components, heading, maturity, disease reaction, etc. The effect of sowing time, location and genotype and their different interaction levels were significant for most of the traits. Wheat yield was significantly reduced in ILS condition as compared to the ITS condition. Regarding location, Dinajpur was better place for wheat production than other tested places. The mean value of the thousand-grain weight (TGW) of all genotypes was higher as compared to all check varieties. Out of eleven genotypes, ten produced a higher yield than BARI Gom 26, five produced a higher yield than BARI Gom 32. All the eleven genotypes were out yielded of the check variety BARI Gom 21. The highest yield (4099kg ha-1) was obtained in Dinajpur and the lowest yield (3108 kg ha-1) was obtained in Jamalpur. Genotypes, BAW 1290, BAW 1293, BAW 1317, BAW 1318 showed comparatively better performance in ILS condition representing that these advanced wheat lines were less affected by terminal heat stress under late sowing condition.
PaH_Studia Sociologica_2_2018.indd

Subjective well-being is usually studied with respect to marital and occupational status, income or subjective health. Conversely, research examining the relationship between this phenomenon and crime related factors is still relatively limited. This study therefore aims to extent the current knowledge in this area. Using data from the fifth wave of the European Social Survey for the Czech Republic, in which 2386 respondents participated, we conduct a hierarchical regression analysis to find out to what extent victimization experience and fear of crime influence life satisfaction and happiness of Czechs. The results of the analysis reveal a direct relationship between fear of crime and subjective well-being. On the contrary, victimization affects life satisfaction and happiness indirectly via the fear of crime. Surprisingly, a decrease in life satisfaction is greater for fearful men than fearful women, whereas there are no gender differences regarding the fear of crime – happiness link.
Using Sweeping Jets on Swept Wings

Tests were carried out on a 45° swept back wing that is highly unstable in pitch due to its large aspect ratio and sweep-back angle. The tests were carried out at velocities of 20-40 meters/second at a representative free stream Reynolds numbers approaching 10. The wing being based on a NACA0012 airfoil had a round leading edge that prevented the generation of a leading edge vortex prior to tip trailing edge stall, thus its first pitch-up departure was due to flow separation at the tip. The interaction between the tip separation and the leading edge vortex resulted in another non-linear pitch behavior. Finally, at larger incidence angle the leading edge vortex propagated inboard and the trailing edge separated region moved upstream. This wing would have been uncontrollable in pitch, were it not for the introduction of active flow control. In this case a single sweeping jet actuator could extend the trimmed incidence angle by 5° to 7°, thus avoiding the pitch break and almost doubling the usable lift coefficient. Balance results, flow visualization and Pressure Sensitive Paint were used to correlate the quantitative results to flow physics.
Optimal Banking System for Private Money Creation

By taking deposits and making loans, banks create private money in an economy– the bank deposits. In this paper I study how the banking system should be designed such that banks can most efficiently create these money-like assets that are both liquid and safe. An endogenously created common pool of liquidity is at the core of this private money creation process– loans made by one bank can generate fresh supply of liquidity to the banking sector before they pay off, which helps to ensure the safety of bank deposits under the exposure to liquidity shocks. I show that under a setting of incomplete markets and incomplete contracts, three market failures potentially plague the private creation of safe assets. First, an incentive problem can lead to ex-ante underproduction of the liquidity pool, when banking sector is subject to idiosyncratic liquidity risks. Second, a commitment problem can result in ex-post over-use of the liquidity pool, when banking sector is subject to systemic liquidity risks. Interestingly, more competitive banking markets ensure more efficient ex-ante incentive provision and hence alleviate the under-production problem; however, increased competition also introduces an ex-post commitment issue, which exacerbates the over-use problem. Finally, an ex-ante coordination problem potentially arises when banking markets become sufficiently competitive: no private safe assets can be created in the economy without proper liquidity regulations (e.g. uniform reserve requirements) being imposed. The analysis has implications on regulations of banking markets and bank liquidity for enhancing economy’s resilience to negative shocks.
Estimation of the parameters of the reduced RUM model by simulated annealing

In this study, a simulation-based method for computing joint maximum likelihood estimates of the reduced reparameterized unified model parameters is proposed. The central theme of the approach is to reduce the complexity of models to focus on their most critical elements. In particular, an approach analogous to joint maximum likelihood estimation is taken, and the latent attribute vectors are regarded as structural parameters, not parameters to be removed by integration with this approach, the joint distribution of the latent attributes does not have to be specified, which reduces the number of parameters in the model.
Aperiodic Model Predictive Control for Networked Control Systems

Networked Control Systems (NCSs) are systems whose sensors, actuators, and controllers are spatially distributed over communication channels. On one hand, it is well-known that a major concern is the energy consumption of battery powered devices due to the network communications. Thus, it is of great importance to reduce communication frequencies between the plant and the controller. On the other hand, many control systems are typically subject to hard constraints, such as actuator saturations. Therefore, this thesis proposes a control framework by applying ‘aperiodic control’, which achieves communication reduction in NCSs, and ‘Model Predictive Control (MPC)’, which takes into account hard constraints. Throughout the thesis, this combinational control scheme is referred to as ‘aperiodic MPC’. In Chapter 1, the purpose and the outline of this thesis are given. The purpose of the thesis is to provide a control framework to reduce communication frequencies between controller and the plant, while at the same time guaranteeing both control performance and the satisfaction of hard constraints. In Chapter 2, some basic methodologies of aperiodic control and MPC are given. In Chapter 3, a control problem of linear systems is considered to formulate an aperiodic model predictive control. In the aperiodic formulation, the timings for sensors to transmit state measurements are determined based on Lyapunov stability, so that the stabilization of the system and communication reduction for NCSs can be achieved. In Chapter 4, an aperiodic formulation of MPC is proposed for nonlinear input-affine systems, which are thus provided for a more general class of systems than the ones in Chapter 2. As with Chapter 2, the way to communicate between the plant and the controller is given based on Lyapunov stability. In Chapter 5, an aperiodic formulation of MPC is proposed for a more general class of systems than the ones presented in Chapter 3 and 4. In particular, the author will derive a threshold between the predictive states and the actual state, such that feasibility of the optimal control problem and stability are both guaranteed. The derived threshold is provided as a criterion for the communication timing between the plant and the controller, so that both control performance and communication reduction are achieved. In Chapter 6, some conclusions are provided.
