The aim of this paper is to advance in the ﬁeld of the development of low-cost synthesis techniques easy to transfer at an industrial scale for electrolyte functional materials in intermediate temperature solid oxide fuel cells (IT-SOFC). We developed an original sol–gel route to synthesize La 9.33 Si 6 O 26 oxides. This approach is straightforward, inexpensive, versatile and it produces pure powders with controlled size and morphology. Via sol–gel route, crystallization temperature of such phases are drastically reduced: 800 8 C in comparison with 1500 8 C in solid-state conventional routes. The dependance of the nature of the phases was studied by varying several parameters as the hydrolysis rate, the volumetric ratio of catalyst to TEOS and the silicon concentration. All these parameters affect the homogeneity of the gel and thus, the purity of the oxides obtained after heat treatment in air. These oxyapatite materials have particle size of about 100 nm after heat treatment at 1000 8 C. The use of these powders for ceramic processing allows a decrease of the sintering temperature of more than 200 8 C.
RESIDENTIAL BURGLARY IN SOUTH AFRICA : WHY INDIVIDUAL HOUSEHOLDS ADOPT REACTIVE STRATEGIES

Residential burglary remains a serious problem in South African society and will probably continue to be a problem for as long as large sections of the population are experiencing unemployment, estimated at as high as 40 percent of the population, and the accompanying poverty and relative deprivation. At an average rate of more than 590 residential burglaries per 100 000 of the population per year for the period between 1994 and 1999, residential burglary can be regarded as the most common crime in South Africa. People from all spheres of life, the “poor” as well as the “rich”, are exposed to the risk of becoming a victim of residential burglary. A comparison of the crime ratios for the 15 most serious crime categories for the period between 1994 and 1999, is shown in Table1.
Field trials with the diatomaceous earth SilicoSec ® for treatment of empty rooms and bulk

Diatomaceous earths (DE) are fossil diatoms (phytoplankton) that contain silicon dioxide (SiO2), the particles absorb the waterproof lipids from the arthropod cuticle resulting in death through desiccation. The DE SilicoSec is registered in Germany. The field trials presented here were performed in order to determine (1) the efficacy of SilicoSec under temperate Central European climatic conditions, (2) the distribution in empty rooms and (3) the possible effect of different surface materials. For empty room treatment, a 41 m2 storage room was treated with 20 g/m2, the total surface treated including walls was 145 m2. At 19 sampling points the amount of DE on the floor was determined. Distinctly less DE attached to the walls compared to the floor, and an uneven distribution on the floor ranging from 2.6 to 49.5 g/m2 with a mean±SD of 15.4±14 g/m2 per sampling point was measured. Additionally, test pieces with 5 different surface types were placed in the treatment room prior to the treatment. Adult Tribolium confusum and Cryptolestes ferrugineus were placed on all surfaces at 15 to 19°C and 65-81% r.h. Mean corrected mortality after 14 d in T. confusum and C. ferrugineus was 94% and 65%, respectively. No significantly different mortality was recorded for T. confusum depending on surface type, but in C. ferrugineus significantly less beetles (20%) died on concrete flagstone compared to natural flagstone, glazed ceramic flagging, plywood and porcelain stoneware. For bulk grain, 10 t of wheat were treated with either 0.7 kg/t or 2 kg/t DE. Sitophilus granarius, Oryzaephilus surinamensis and C. ferrugineus adults were placed in vials with treated wheat together with data loggers and placed deep within the bulk for 19 d. Corrected mortality was around 90% for all treatments except for S. granarius at the lower dose where 60% mortality was achieved only.
Gastight Paperboard Package A new Step in Food Packaging Packages

Introduction The use of material originating from renewable resource is a prime aim in packaging development, nowadays. In this context, paperboard in combination with a thin plastic film coating offers a suitable compromise of properties but, until now, it has not been possible to produce a packaging from coated paperboard that offers sufficient gas barrier properties. Such properties, however, are indispensable for many food packaging solutions and often do not leave any alternative but plastics. Barrier properties against gases are the most demanding requirements for any packaging material, package design and packaging process. Prevention of gas penetration can be requested in either direction, i. e. from the surrounding atmosphere into the interior of the package as well as vice versa. The latter for example applies to so-called Modified Atmosphere Packages (MAP) which uses inert gases to block out oxygen and prevent microbial growth in order to increase the shelf life of food products. No matter what type of protection is needed, the tightness of a package is always a function of the specifics of the barrier layer’s permeability and the tightness of the seal. There are of course a number of materials with excellent barrier properties against gases which can be combined with paper or board. In many case, however, such barrier layers are brittle and can easily be damaged during the forming processes. Capabilities of paperboard-based packaging processes In the majority of cases, however, particularly as far as food packages are concerned the gas tightness of a package is a major condition to achieve adequate shelf life. Paper based products in this case exhibit severe disadvantages. Folded boxes for example have many cutting edges which have to be sealed, and their production requires several forming steps which, in the end, lead to complex procedures and a higher risk of failure. The resulting failure cannot be tracked to its source, easily due to the large number of processing steps. Using the pulp moulding process in barrier applications means that a 3D formed part has to be coated with barrier layers which is difficult and demanding in terms of production time and costs. Composite cans consisting of a wound paper body and a laminated aluminium foil are able to provide barrier properties, but their production also requires a rather complex process. Furthermore the sealing at top and bottom requires accordingly materials and joining technology. The most reasonable way to produce packaging components from coated paperboard for barrier application is 3D forming. This process is known for microwave or frosted food cups, but the formed parts cannot be sealed gastight due to the capillary tubes in the sealing area caused by wrinkles.
Sub ject-Based Reference Values in Thyroid Function Tests

To evaluate the diagnostic value of subject-based reference values in thyroid function tests, we compared intra-individual and inter-individual variation. Five specimens were collected over a period of 2 weeks from each of 47 normal subjects, 29 women and 18 men, aged 20-47 yrs. T4, FT4, T3, and FT3 were assayed by RIA, and TSH by a sensitive immunoradiometric assay. One-way ANOVA for each test was statistically significant for a main subject effect, indicating that the subjects differed in their personal mean values for the thyroid function tests (T4, P<0.01; FT4, P<0.05; T3, P<0.01; FT3, P<0.05; TSH, P<0.01). The ratio value (intraover inter-individual variation) was T4, 0.41; FT4, 0.60; T3, 0.53; FT3, 0.63; TSH 0.36. The data indicate that conventional reference values are insensitive when compared to subject-based reference intervals in assessing the thyroid status of a given subject. Reactivity of the thyroid to the stimulation of endogenous TSH was assessed by the ratio AFT3/ATSH in TRH stimulation tests. A positive correlation between basal FT3 and A FT3/L\ TSH (r==0.566, P<0.05) indicates that the thyroid with higher reactivity to TSH secretes more daily thyroid hormone. Negative correlation between basal TSH and AFT3/ATSH (r=-0.536, P<0.05) means that a subject with lower reactivity of the thyroid needs a higher basal TSH level to compensate. The thyroid reactivity to TSH may be an important determinant for the individuality of the pituitary-thyroid axis.
A Appendix : Specification Search A . 1 Without quality correction

A fruitful recent theoretical literature has related human capital and technological development with income (and wages) inequality. However, empirical assessments on the relationship are still scarce. We relate human capital and total factor productivity (TFP) with inequality and discover that, when countries are assumed as heterogeneous and dependent cross-sections, human capital is the most robust determinant of inequality, contributing to increase inequality, as predicted by theory. There is evidence of great heterogeneity on the effects of TFP and Openness across countries. These new empirical results open a wide avenue for theoretical research on the country-specific features conditioning the causal relationship from human capital, technology and trade to inequality.

A ug 2 01 6 Collective resonance fluorescence in small and dense atom clouds : Comparison between theory and experiment

We study the emergence of a collective optical response of a cold and dense Rb atomic cloud to a near-resonant low-intensity light when the atom number is gradually increased. Experimental observations are compared with microscopic stochastic simulations of recurrent scattering processes between the atoms that incorporate the atomic multilevel structure and the optical measurement setup. We analyze the optical response of an inhomogeneously-broadened gas and find that the experimental observations of the resonance line shifts and the total collected scattered light intensity in cold atom clouds substantially deviate from those of thermal atomic ensembles, indicating strong light-induced resonant dipole-dipole interactions between the atoms. At high densities, the simulations also predict a significantly slower decay of light-induced excitations in cold than in thermal atom clouds. The role of dipole-dipole interactions is discussed in terms of resonant coupling examples and the collective radiative excitation eigenmodes of the system.
Improving Patient Flow in Emergency Departments with OR Techniques: A Literature Overview

The emergency department (ED) is an interesting field for operations research (OR) and operations management (OM) researchers. Having timevarying arrivals and heterogeneous patients that need to be treated in consecutive processing steps by several doctors, nurses and other employees, it is a complex environment to control. The difficulty to control EDs often results in (over)crowded EDs. In general, an ED is said to be experiencing periods of crowding when the demand for ED services exceeds the available ED resources (Higginson, 2012). ED crowding is a worldwide phenomenon with regional influences (Jayaprakash et al., 2009) and may cause a myriad of operational problems like patients being treated in hallways, excessive length of stay (LOS) and wait times, patients leaving without treatment or even medical errors and increased mortality. Descriptive studies that define crowding (Hwang & Concato, 2004), examine the causes and effects (Richardson & Mountain, 2009; Hoot & Aronsky, 2008; Asplin et al., 2003), and propose models to measure crowding (Hwang et al., 2011; Higginson, 2012) can be found in the medical literature. Applying OR and OM techniques to improve the performance of EDs is needed now more than ever since health budgets are tight, demand for health care services is rising and higher performance standards are being demanded simultaneously.The scope of the articles that have been selected for discussion and the search method are delineated in Section 1.1 and Section 1.2 respectively. Section 2 will provide an overview of the selected articles that use OR and OM techniques to improve ED processes. Considering the existing literature, Section 3 will outline my future research perspectives.

Deregulation of BCL 2 family proteins in B-cell lymphomas — molecular , pathogenetic , clinical and therapeutic implications

Ability of differentiating B-cells to respond to death signals is essential for the maintenance of immune system homeostasis. Abnormalities in the execution of these signals are therefore dangerous and potentially oncogenic. BCL2 (B-cell CLL/lymphoma 2) family proteins act as a critical regulators of apoptosis. The BCL2 family consist of pro-survival and pro-apoptotic proteins, playing distinct roles in the transduction of death signals. Deregulated expression of these proteins is a frequent feature of B-cell tumors and might occur through structural and
The Relation Between Loyalty and Control : Establishing Goal Congruence

Loyalty is a concept examined since the work of Porter and his colleagues in the 70’s. In the early 90’s, Becker (1992) started to disentangle the concept of loyalty into different foci and bases of commitment. This was the first time a pronounced relation was found between loyalty and performance in the form of commitment to the supervisor. In this thesis, the focus shifts to loyalty in the form of a foci of organizational commitment and a base of congruence of employee and organizations norms and values, as an answer for the agency conflict, and the relation with in-role performance. The survey results provide, for the first time, evidence of a positive statistically significance of this relation.

D S ] 2 8 Fe b 20 18 Constant-Factor Approximation for Ordered k-Median

We study the Ordered k-Median problem, in which the solution is evaluated by first sorting the client connection costs and then multiplying them with a predefined non-increasing weight vector (higher connection costs are taken with larger weights). Since the 1990s, this problem has been studied extensively in the discrete optimization and operations research communities and has emerged as a framework unifying many fundamental clustering and location problems such as k-Median and k-Center. This generality, however, renders the problem intriguing from the algorithmic perspective and obtaining non-trivial approximation algorithms was an open problem even for simple topologies such as trees. Recently, Aouad and Segev were able to obtain an O(log n) approximation algorithm for Ordered k-Median using a sophisticated local-search approach and the concept of surrogate models thereby extending the result by Tamir (2001) for the case of a rectangular weight vector, also known as k-Facility p-Centrum. The existence of a constant-factor approximation algorithm, however, remained open even for the rectangular case. In this paper, we provide an LP-rounding constant-factor approximation algorithm for the Ordered k-Median problem. We obtain this result by revealing an interesting connection to the classic k-Median problem. We first provide a new analysis of the rounding process by Charikar and Li (2012) for k-Median, when applied to a fractional solution obtained from solving an LP relaxation over a non-metric, truncated cost vector, resulting in an elegant 15-approximation for the rectangular case. In our analysis, the connection cost of a single client is partly charged to a deterministic budget related to a combinatorial bound based on guessing, and partly to a budget whose expected value is bounded with respect to the fractional LP-solution. This approach allows us to limit the problematic effect of the variance of individual client connection costs on the value of the ranking-based objective function of Ordered k-Median. Next, we analyze objective-oblivious clustering, which allows us to handle multiple rectangles in the weight vector and obtain a constant-factor approximation for the case of O(1) rectangles. Then, we show that a simple weight bucketing can be applied to the general case resulting in O(log n) rectangles and hence in a constant-factor approximation in quasi-polynomial time. Finally, with a more involved argument, we show that also the clever distance bucketing by Aouad and Segev can be combined with the objective-oblivious version of our LP-rounding for the rectangular case, and that it results in a true, polynomial time, constant-factor approximation algorithm.

Study on the Composite EM Scattering from Sea Surface with Ship Based on Kd-Tree Accelerated Hybrid Model

A hybrid model based on the geometrical optics and physical optics (GO-PO) method and facet-based asymptotical model (FBAM) for the composite EM scattering from sea surface with ship has been previously developed. But, the GO-PO method faces a difficult problem that the lower efficiency in testing the visibility of patches to the incident and reflected waves. Hence, to improve the computation efficiency of the GO-PO method, a kd-tree accelerated hybrid model is presented in this paper. The kd-tree method firstly carries out the intersection test between the ray and the bounding box where the patch is located before the operation between the ray and the patch. If the distance parameters of the bounding box do not meet the requirement, the ray is not necessary to enter the bounding box, which can reduce the needless intersection tests. Numerical results show that the proposed kd-tree accelerated hybrid model could improve the efficiency about three times and could be applied to the study of composite EM scattering characteristics of electrically large sea surface with a ship target.

Evaluation of the Antihyperglycemic Effect of N-butanol Leaves Extracts of Iraqi Fumaria parviflora in Alloxan-prompt Diabetic Rats

Objective: In this research, we evaluated the antihyperglycemic effect of leaves of Fumaria parviflora (F. parviflora) and implied mechanisms by using in vivo models of hyperglycemia. Materials and Methods: Fifty male Wistar rats weighing 180-220 g were applied for the research. Soxhlet ethanolic extract of leaves of F. parviflora (EFP ) was prepared. Alloxan-induced diabetic rats were orally remedied with the extract (50, 100 or 200 mg/kg/day), metformin (200 mg/kg/day) for two weeks. Another animal received only extract, alloxan (diabetic control) or vehicle (control). Results: pretreatment effect of plant extract on blood glucose levels of diabetic rats Blood glucose levels in all extract pretreated groups was lower (p<0.05) when compared with the levels in rats that received alloxan alone, Rats that we are treated with plant extract had normal blood glucose levels that ranged for 73.00±1.5 to76.00±0.54 mg/dl at the beginning (first day) of experiment. Blood glucose levels in these animals declined during the period of extract administration, but the values obtained were not significant compared to control excluded those that were obtained on the 14th day, p < 0.05 Conclusion: Leaves of F. parviflora possess blood glucose-lowering effects In Alloxan-Induced Diabetic Rat, The findings of a study indicated that F. parviflora has a significant hypoglycemic effect on Alloxan-induced diabetic rats with no effects in blood glucose levels of normal rats.

The case for euthanasia and physician-assisted suicide

The concept of dying by euthanasia and indeed physician-assisted suicide is a highly emotive one. Assisted dying arouses intense feelings both in favour and against. The prospect of enduring a long drawn out dying process generates both fear and apprehension in both terminally ill and chronically ill patients. Many of them wish to choose the time and manner of their death. On the other side, passionate, mainly religious groups have campaigned long and hard to deny suffering people assistance to die. As the law currently stands in Australia, there is a complete ban on both euthanasia and assistance in suicide. Even following a request by a patient, a medical practitioner who directly takes the life of his or her patient, can be charged with murder or manslaughter. Despite the repeal of laws that forbade committing or attempting to commit suicide, laws still exist which proscribe the provision of assistance to another to commit or attempt to commit suicide.
Ceelen-Gellerstedt syndrome in an elderly Indian man: Case report of an unusual case

Ceelen-Gellerstedt syndrome, also known as idiopathic pulmonary hemosiderosis (IPH), is a rare disease characterized by recurrent pulmonary alveolar hemorrhages associated with a classical clinical triad of hemoptysis, unexplained iron deficiency anemia, and diffuse pulmonary infiltrates on imaging. We present a case report of Ceelen-Gellerstedt syndrome in an elderly 69-year-old Indian male patient, which is an unusual case as the condition is more common in children and young adults. Diagnosis was suspected on high-resolution computed tomography (HRCT) scan, which revealed diffuse areas of consolidation, ground glass opacities, and septal thickening with perihilar and basal predominance and further workup with bronchoscopy and bronchoalveolar lavage helped to confirm the diagnosis.
