Renal transplantation is the best alternative renal replacement option for patients with advanced chronic kidney disease. However, the supply of young donors is limited, and does not cover the demand of patients on the renal transplant waiting list, for this reason are being used older donors and exists a high discard rate of those organs base on pathological results (score) of the preimplant renal biopsy.
 There are several methods to evaluate the quality of the kidneys and the Kidney Donor Profile Index (KDPI) has acquired special relevance to decide the perform of preimplant renal biopsy. Based on the score, a preimplant renal biopsy is performed, which is decisive in certain cases.
 However, there is poor evidence to support this decision, which can be described as "conservative," since there is not enough certainty that there is influence of the preimplant biopsy score score on graft survival.

 389 biopsies of kidney transplant donors of cadaver donors in brain death and asystole type III were included. Donors in asystole type II, combined and live, were excluded. Samples examined by the same pathologist and in paraffin (no case by freezing). A graft survival analysis was performed based on the results of the renal biopsy (score). Likewise, a multivariate analysis of graft survival was carried out including, in addition to the results of the renal biopsy, results such as the age of the donor and recipient and the KDPI.

 graft survival was compared between two transplant subpopulations in our hospital based on whether a preimplant biopsy was performed. According to the data used there are no significant differences in graft survival between transplants in which biopsy has been performed and those that have not.

 our work shows, as is currently the case in the literature, the absence of influence on the score of the preimplant biopsy score on graft survival.


There is evidence that obesity is associated with impairments in executive functions, such as deficits in decision‐making, planning or problem solving, which might interfere with weight loss in obese individuals. We performed a systematic review and meta‐analysis of decision‐making abilities, as measured with the Iowa gambling task (IGT), in obesity without eating disorders.


A numerical and experimental study has been conducted to investigate the anisotropy of thermal dispersion in porous media. A successful attempt was made to numerically investigate the longitud nal thermal dispersion coefficient, considering a macroscopically uniform flow through a periodic model of square rods. The present numerical experiment confims that the longitudinal dispersion is substantially higher than the transverse dispersion. It has been found that the predicted apparent conductivities agree well with the experimental data.


This paper examines the clear cut separation and distinction of the role and business of the church and the state. Social disorder, wars and conflicts of diverse natures have always resulted from the inefficient link between the church and the state. My focus in this paper is to justify that, without the establishment of a real boundary between the church and the state, there can be no certain end to the controversies that will be always arising. This principle of separation is geared toward the secularization of politics, as a means of putting the different sectors of the society in their right positions, by emphasizing on the fact that, the affairs of heaven do not have any business with those of the earth and restricting the temptation of power abuse by either the church or the state or both. I emphatically portray that, the church must be separated from the state exactly and absolutely because it is considered as the first method to resolve the different problems related to the misuse of power that usually occur within the society. I further admit that, the church is mainly concerned about the interests of men's souls which involve exercising purity, God worship, living a holy and decent life, aimed at acquiring the salvation of individual souls. Finally, I conclude that, the aspiration of the state is outward, external or public and centered on the commonwealth, geared toward the procuring, preserving and advancing of civil interests which include: life, liberty, indolence of the body, and the possession of outward things, such as: money, land, houses, furniture.


The dual-head positron emission tomography (PET) systems have an importance role in the preclinical and clinical applications. This paper focuses on developing a simplified model based on distance-driven (DD) and solid angle method to calculate the system response matrix (SRM) for the dual-head PET system. The subsampling schemes, including the subvoxel scheme and multi-DD scheme were introduced. The full width at half maximum (FWHM), coefficient of variation (COV), and contrast were computed and compared with that of using the Monte Carlo (MC)-based and multiray methods. In this paper, the dual-head PET system is configured with a 5 cm separation and <inline-formula> <tex-math notation="LaTeX">$52 \times 104$ </tex-math></inline-formula> mm3 detection area of each head. The size of each crystal is <inline-formula> <tex-math notation="LaTeX">$13\times 1.89\times 1.89$ </tex-math></inline-formula> mm3. The results indicate that the rods with 1.0 mm diameter are resolved basically with the 100th iteration when the voxel is virtually divided into <inline-formula> <tex-math notation="LaTeX">$2\times 2\times 2$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$4\times 4\times 4$ </tex-math></inline-formula> subvoxels, which is comparable to that with the MC-based SRM. When the voxel is divided into four cuboid-shaped subvoxels, the rods with 1.0 mm diameter are resolved with the 80th iteration and the COV performs well in the simulation experiment. Overall, the proposed SRM model achieves a good compromise between image quality and calculation time.


The TE-to-TM optical mode conversion that takes place when magnetostatic waves (MSW) and a guided light beam propagate collinearly in an yttrium-iron-garnet (YIG) film is investigated. The experimental results show unexpectedly high intensity and broad bandwidth when microwave power levels on the order of 35 dBm are used. This effect is clearly nonlinear, and it is speculated that it could be due to spin wave excitation or to high transducer current effects. The experiments were carried out between 4 and 7 GHz using 1.3- mu m radiation. >


The paper presents the generalization of the modification of classical boundary integral equation and obtaining parametric integral equation system for 2D elastoplastic problems. The modification was made to obtain such equations for which numerical solving does not require application of finite or boundary elements. This was achieved through the use of curves and surfaces for modeling introduced at the stage of analytical modification of the classic boundary integral equation. For approximation of plastic strains the Lagrange polynomials with various number and arrangement of interpolation nodes were used. Reliability of the modification was verified on examples with analytical solutions. Copyright © 2016 John Wiley & Sons, Ltd.


This paper highlights results from the first of a series of hierarchical simulations aimed at assessing the modeling requirements for application of the large eddy simulation technique to cryogenic injection and combustion processes in liquid rocket engines. The focus is on liquid-oxygen-hydrogen coaxial injectors at a condition where the liquid-oxygen is injected at a subcritical temperature into a supercritical environment. For this situation a diffusion dominated mode of combustion occurs in the presence of exceedingly large thermophysical property gradients. Though continuous, these gradients approach the behavior of a contact discontinuity. Significant real gas effects and transport anomalies coexist locally in colder regions of the flow, with ideal gas and transport characteristics occurring within the flame zone. The current focal point is on the interfacial region between the liquid-oxygen core and the coaxial hydrogen jet where the flame anchors itself.


Chinese perch or auha is a rare species that is under the threat of extinction. In Prymorye it is found in the Ussuri River, the Songach River and Lake Khanka. The population of this species has declined significantly due to intensive catch of sires in the main spawning grounds outside Russia. The possibility of breeding the Chinese perch auha in southern Primorye is considered in this paper. From 12 June to 20 June 2014 in the lower reaches of the Melgunovka River of Lake Khanka basin four specimens of Chinese perch were caught (1 female and 3 males), sizes from 32 to 70 cm, weighing from 0.6 to 4.96 kg. To stimulate the mat-uration of sexual products in the perch auha the preparation "Nerestin 6A" was applied. The female Chinese perch auha spawned in captivity did not result in the hatching of larvae because of raising the temperature of the water in the pond and Weiss machines. The sires were brought to the Primorsky Oceanarium, Far Eastern branch of Russian Acad-emy of Sciences, and placed in the pool of re-search adaptive premises where they are now: fe-male was 32 cm, 0,815 kg and two males, 40 and 50 cm, weighing 1,885 and 2,380 kg. On the basis of our own and available published data we got the normative indices on artificial reproduction of Chi-nese perch in southern Primorye (within the bounds of the Federal State Budgetary Institution "Primorrybvod" program on reproduction of rare and endangered species of fish in 2013-2016)

The exact estimation of configuration activities on the structure is imperative in basic plan as it altogether influences the last outline and targets. Any mistake in the estimation of configuration activities may prompt to wrong after effects of auxiliary investigation on the structure and prompt to the unlikely measuring of its basic individuals or even crumple of the structure. Accordingly it is vital to represent the most antagonistic impacts of live loads on the structure. The thought of example stacking relies on upon the proportion of dead to live load and the sort of basic part. Nowadays the greater parts of the architects are not considering the distinctive live load examples to get the unfriendly impact of the structure. Considering the live load to all the section boards may not fitting to gauge the plan parameters. In this unique situation, an endeavour is required to see the impact of example live load on the structure under seismic burdens. The impact of example load might be not quite the same as uncovered edge structure and furthermore infill structures. For the present work a customary symmetrical building will be picked and the structure is stacked with various examples live stacking is dissected by utilizing reaction range technique for seismic load case with and without infill walls. A limited component programming ETABS will be utilized for the examination of structures. The conduct of the structure will be examined as far as base shear, story shear, storey floats, day and age and furthermore twisting minutes and shear drives in identified sections. © 2017 Elixir All rights reserved. Elixir Civil Engg. 104 (2017) 45996-46005 Civil Engineering Available online at www.elixirpublishers.com (Elixir International Journal) Tele: E-mail address: firstname.lastname@example.com © 2017 Elixir All rights reserved P.Mallikharjuna RAO and CH.Veeruttam Kumar / Elixir Civil Engg. 104 (2017) 45996-46005 45997 ASCE 7-05 Section 4.6 states "The full intensity of the appropriately reduced live load applied only to a portion of a structure or member shall be accounted for if it produces a more unfavorable effect than the same intensity applied over the full structure or member." What this means is that you need to arrange the live load so as to cause maximum effect in your members. You must design your structural elements so that they have sufficient strength to support all possible arrangements of live load. Consequently your analysis needs to provide you with envelope diagrams for each member. Envelope diagrams are internal force diagrams that envelop all the possible values of force at each location along the member. So examples are used below to explain method for determining envelopes. This can seem daunting task as you need to do multiple load cases to account for the various loadings on your structural system. For statically determinate structures, it is often easy to establish critical loading scenarios for shear, moment, reactions, and deflection. Unfortunately for continuous, statically indeterminate structures this is not so obvious and the use of influence lines becomes extremely useful. Ugur Ersoy (1992) worked on live load arrangements for multi-story frame analysis. He mentioned that 'Code require analyses based on live load arrangements producing the most unfavorable effects. This requirment leads to hundreds of cases in the analysis of multi-story structures which is neither feasible (even with the use of computer) nor sensible (due to the approximations involved). A reasonable number of cases should be analysed to obtain sufficiently accurate results'. In his work he proposed an apporach which requires the analyses of five cases irrespective of the number of stories and bays as shown in fig.1. Numerical comparisons indicated that proposed approach is simpler and it leads to more accurate results than those proposed earlier. From his work he concluded that the live load arrangement proposed in general seem to yield greater moments as compared to the other practical methods. Fig 1.Arrangement of live loads considered by Furlong (1981). Furlong R.W (1981) worked on rational analysis of multistory concrete structures. Problems to be faced in analysis of structures considering effect of live load patterns. In the work furlong approached the problem of solving the structures for different live load patterns as a practical designer and claimed that all possible live load combinations do not have to be considered for the following reasons. 1. As the number of load cases increases, the probability of occurrence of the most critical combinations decreases. 2. Member forces are not very sensitive to loading not adjacent to such members. 3.Linear elastic analysis is just an approximation for reinforced concrete structures in which I and E change due to cracking and creep. Considering these important points, Furlong proposed simple live load arrangements which he claimed would yield reasonable values for shear and bending moment in beams and columns. The live load patterns considered in the study by furlong given in figure 2.2. Robert Park et.al.,(2000) mentioned some of the important points about the live load patterns in analysis of structures. In addition to the general structural characteristics, the ratio of live load to dead load, or movable load to total load, is very important in determining the significance of pattern loads. Pattern loads are obviously of much greater potential importance in a structure in which the live load is several times the dead load than in a structure in which the live load is only part of the dead load. Kulkarini J.G, Kore P.N., S.B.Tanawade (2013) studied the analysis of multi story building frames subjected to gravity and seismic loads with varying inertia. his paper presents an elastic seismic response of reinforced concrete frames with 3 bay, 5 bay and 7 bay 9 storey structures which have been analyzed for gravity as well as seismic forces and their response is studied as the geometric parameters varying from view point of predicting behavior of similar structures subjected to similar loads or load combinations. 3.Modelling and Analysis Generally structures are subjected to dead and live loads. Dead loads are constant through out of the life of the structures where as imposed loads or live loads vary time to time and position to position within the structure. Live loads position influences the design forces in different elements of the structure. In the present study a G+9 floors symmetrical building is chosen as shown in figure plan, elevation and isometric view respectively. Building is having plan dimension of 30 m ×30m , Six bays in each direction and each bay of 5 m. In all the models dead is considered full which includes self-weight of the slab, beams, columns, floor finishes and wall loads. There are Eight different live load patterns are considered for the study viz., loading is in alternate bays, chess board kind of pattern, live load only at the corners panels, loading is only in central panels, full live load in all panels etc. as shown in figures In this paper a detailed report is given which includes models, loading patterns, identified columns, beams bars for the study, parameters considered for the design. The study is conducted in three phases. In the first phase the models are analyzed for static load condition, in the second phase study the models are analyzed for seismic load conditions without considering infills. In the third phase study the models are analyzed for seismic load by considering infills. In seismic analysis response spectrum method has been used in phase 2 and phase 3 study. Columns and beams are identified for the study. A finite element software ETABS is used for the analysis. Properties considered in the models The following properties are considered for the analysis. In the first phase study Type of frame: Ordinary RC moment resisting frame fixed at the base. Number of storey: 10 story (G+9).

The four preceding workshops on RF superconductivity have witnessed an extraordinary rapid development of the teclmology of the high-temperature superconductors (HTS). Up to 40 different HTS compounds have been successfully synthesized by different physical and chemical evaporation and ablation teclmiques. Ingenious methods to characterize the temperature, frequency and power dependent surface impedance Zs and to optimize the material have been developed and thoroughly adopted. Although some fundamental physics questions are still puzzling, many possible applications of planar microwave components have been identified which utilize epitaxial HTS thin films at frequencies between I MHz arrl 100 GHz. These can be devided into passive or active, based on the linear or the nonlinear dynamic conductivity of HTS, and analog or digital. This review tries to summarize the present phenomenological understanding of Z. of the HTS compounds YBa2Cu30 7.x and n2Ba2CaCu2q~+y, its short-term impact on different categories of microwa\'e circuit components and the resulting technical and economical potentials for implementing such HTS dnices in operational high-frequency systems.


A city's complex anatomy is hard to percept in today's world. The syntax of modern cities is argued to have become too enriched with various elements to the verge of being incapable of reflecting a clear and well defined image. This consequently reflects on the difficulty of wayfinding in modern cities. Traditional methods of wayfinding whether cognitive (as in retrieving a certain trip path from the mind) or physical (such as sketch maps and signs) still prove their ability to throw an authentic and unified air upon cities. Nevertheless, the image reflected by such an authenticity and unification is not always necessarily up-to-date and heartily complete. Cities evolve and accumulate strata of the built environment along with human activities over one another. This being said, and despite not being obsolete, traditional methods of wayfinding are strongly argued not to be fully capable of coping with the fast and overwhelming metamorphosis of the city's image in modern times. To this end, the use of digital tools to complete the image of the city and accordingly enrich the process of wayfinding has become an imperative in our modern world. Such a use of digital tools reaches beyond the simplicity of dependence on computerized gadgets yet is optimally targeted to offer a better perception of the city and aid in formulating a clearer mental map of its complex and rich surroundings. The aim and scope of this paper is to explore the use of digital techniques (with special reference to Virtual Reality) in providing a deeper perception of a modern city's anatomy that can be well carved in wayfinders' composed image of the city. The paper follows a multidisciplinary methodology in examining the subject under study. Analytical and critical efforts are exerted with the aid of a literature review. The paper commences with the definition of wayfinding and navigation in order to set the ground for discussing the physical and cognitive aspects of the process. The paper then proceeds to discussing and critiquing the need for a new set of tools (digital devices) to complement the traditional physical and cognitive aspects of the wayfinding process. The discussion develops into a brief yet thorough analysis of the capabilities of a number of the major digital devices used for wayfinding in today's modern cities. The main aim behind this discussion is to clarify the role of digital devices in synthesizing a more thorough image of the city. The paper finally interprets its discussions and findings into a set of recommendation regarding the use of digital devices with Egypt as the case analyzed. This is intended to better demonstrate the various factors and considerations that govern the use of digital devices for wayfinding in todays' world.


Mango village is one of the areas that participates in various welfare programs for the local community, where in this village there are still people who are far from prosperous because of various factors that affect the welfare of the local community, one of which is the jobs owned by the community. Therefore, it is important for people to understand that work also greatly influences the level of welfare for their own lives, so that they are fulfilled in the economy, education and others. Therefore the author wants to create a system that can assist the government in developing community welfare programs in Mango Village by knowing the relationship between work and the level of social welfare. After carrying out the above case trials with minimum support = 25%, confidence = 100% so that the rule results that meet the support and confidence values are obtained, it can be concluded that if the assets owned are A4 (motorcycles), with T2 dependents (3-4), with M2 jobs (Private Employees) and A4 assets (Motorcycles), with P2 income (> 1,000,000 - < 2,000,000), then enter K2 (welfare stage II) with a support value of 20%, 100% confidence.


In submarine environment, sonar imaging is widely used in detection tasks, since the sonar imaging is independent of illumination. However, the capture and transmission under unstable and elusive underwater acoustic channel would inevitably result in quality degradation of sonar images, which might also impede further processing and applications. To measure this distortion, as well as provide a reliable quality indicator of sonar image enhancement, we propose a sonar image utility quality assessment (SIUQA) with a reduced feature set. Different from traditional metrics, we combine perception- and task-aware features in order to make quality indicators more relevant to underwater tasks. Experimental results show that SIUQA has a superior performance compared with the state-of-the-art semi-reference (SR) quality metrics for sonar images.

An increase in the atmospheric concentration of CO, is prolected to cause climate warming. Warming of the permafrost environment could change the balance between carbon accumulation and decomposition processes and substantially disrupt the equilibrium of the carbon cycle. Warming may accelerate the rate of decomposition, which is limited by low temperatures, and thaw deeper layers of formerly frozen organic soils, making them available for decomposition. At the same time, productivity of vegetation may increase in response to warming. The continuous permafrost zone occupies approximately 40% of Russian territory, and 5 % of the land surface area of the world. Disruption of the carbon cycle within the permafrost zone in Russia could have a profound effect on the global terrestrial carbon cycle. To evaluate changes in the carbon cycle within the permafrost environment of Russia, it is necessary to quantify the present carbon pools and fluxes Once the carbon balance is established under the present clunate, potential disruptions under a warming climate can be identlfied. A framework to assess the carbon balance for the continuous permafrost zone of Russia was created. Under the present climate, the phytomass (live vegetation, aboveand below-ground) carbon pool was 17.0 Gt (10' t). The mortmass (coarse woody debris) carbon pool was 16.1 Gt. The litter carbon pool was 6.4 Gt C and the soil carbon pool including peatlands was 139.4 Gt. Live vegetation and plant detritus (mortmass and litter) taken together were approximately one-third of the soil carbon pool. The rate of carbon turnover was 1.58 Gt yr-l and the rate of humus formation was 0.083 Gt C yr-'. The phytomass carbon pool of the permafrost zone was 19 % of the former Soviet Union (FSU) phytomass pool and 3 % of the world biomass carbon pool. The permafrost zone accumulated a significant amount of aboveand below-ground plant detritus (mortmass and litter). Climate warming may cause forest migration to the north and increase net carbon accumulation in shrubby tundra ecosystems and ecosystems on soils of low permeabhty, compensating for possible carbon losses from tussock tundra. Shrubby tundra formations and gleylc soils occupy approximately one-half of the area of the Russian tundra biome. The degradation of permafrost would not directly affect the rate of carbon emissions from mineral soils and peatlands. The present depth of the active layer (i.e. layer of seasonal freezing and thawing) in mineral soils exceeds the depth of the organic horizons. In peatlands, thawing of the active layer could cause an additional mass of organic matter to become available for decomposition. However, thawing of the active layer in peatlands may not be this extensive because of the low thermal conductivity and high latent heat capacity of peat.


The function of resin components, such as methylene donors, methylene acceptors and silica, was investigated in the adhesion of styrene-butadiene rubber (SBR) to zinc during curing with an HRH adhesion system. Adhesion strength was increased with an increase in the ability of polymerization of the donor and acceptor compounds in the adhesion of SBR to zinc. Both the methylene donor (e. g., hexamethylenetetramine) and the methylene acceptor (e. g., resorcinol) migrated to the interface between Zn and SBR during curing reaction. In this case, adhesion strength was generated by forming a reinforcement layer of resin at the interface. The layer is produced by reaction of the methylene acceptor and the donor. In the SBR compound, polymerization of the acceptors and the donors is delayed by the presence of silica, therefore the acceptor and donor are able to migrate to the interface. The resin layer at Zn/SBR interface works not only as a reinforcement layer but also as a binder which connects SBR molecules with zinc. Resorcinol reacted with PbO and then C6H4O3Pb2 was formed. The C6H4O3Pb2 migrated to the interface. This result suggested that the resorcinol acts as carrier as well as a methylene acceptor.

The research adopted the use of the historical approach, in addition to the descriptive approach. This study came to a number of conclusions, the most important of which is: These multi- national companies are influenced by a number of variables such as technological, demographic, economic and social variables. These companies go into business with developing countries according to their specific characteristics. The study concluded to some directives to developing countries. The first priority for investment is local savings. Foreign investment should be directed to productive sectors and not to consumer or services sectors.


The study on child and adolescent dis- closure of sexual abuse is related to primary and secondary prevention, in addition to providing in- terventions for this type of violence. This article aims at characterizing the patterns of disclosure and discovery of sexual abuse, verifying its association to individual factors of the victims and perpetrators (age, sex) and relational factors (familiarity between victims and perpetrators, as well as with the recipi- ent of the disclosure). The study analyzed 232 cases of sexual abuse retrieved from records of three specialized services, one service was local- ized in the Brazilian state of Para (PA) and two in the state Rio Grande do Sul (RS). The patterns of disclosure and discovery were significantly associ- ated to the age and sex of the victims, and the place of the sample (PA and RS). Intentional disclosure was more frequent among female victims (33.5%) and accidental detection was more frequent among males (44.7%). In the sample from PA, accidental detection (46.9%) was predominant, whereas among the victims from RS intentional disclosure prevailed (31.1%). The importance of issues such as gender, developmental stage and influence of cultural and structural factors in public policies to prevent sexual abuse is also discussed.

With the introduction of the national "carbon peaking and carbon neutrality" strategic goals and the accelerated construction of the new generation of power systems, cloud applications built on advanced IT technologies play an increasingly important role in meeting the needs of digital power business. In view of the characteristics of the current power industrial control system operation support cloud platform with wide coverage, large amount of log data, and low analysis intelligence, this paper proposes a cloud platform network security behavior audit method based on FP-Growth association rule algorithm, aiming at the uniqueness of the operating data of the cloud platform that directly interacts with the isolated system environment of power industrial control system. By using the association rule algorithm to associate and classify user behaviors, our scheme formulates abnormal behavior judgment standards, establishes an automated audit strategy knowledge base, and improves the security audit efficiency of power industrial control system operation support cloud platform. The intelligent level of log data analysis enables effective discovery, traceability and management of internal personnel operational risks.


During the design process for Krasnogorskaiya small HPP-1 and HPP-2 the options for the technical solutions were considered and optimal options for the site, layout and the main hydraulic structures: dam, spillway, right-bank dam and silting protection structures were chosen.


Objective
To observe the expression of neural nicotinic acetylcholine receptor subunit α3(α 3nAChR) and extracellular regulated protein kinases(ERK1/2), c- Jun N- terminal kinase(JNK), p38 kinases of mitogen- activated protein kinase (MAPK) pathway in human neuroblastoma cell line SH- SY5Y overexposed to fluoride, and try to investigate the molecular mechanism of cell damage caused by overexposure of fluoride.

Methods
The SH- SY5Y cell with low expression of α3nAChR suppressed by silence interference RNA served as α3nAChR silence group; the normal SH-SY5Y cell served as control group, and the effect of silencing of α3nAChR gene in SH-SY5Y was detected by Western blotting and real-time PCR; SH-SY5Y cell was treated with different concentrations of fluoride (0.000, 0.005, 0.050, 0.500, 1.000, 2.500, 5.000 mmol/L), the safe concentration of fluoride in SH-SY5Y cell was detected by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) assay; the SH-SY5Y cell of control group and α3nAChR silence group were treated with 4.000 mmol/L fluoride for 0, 4, 8, 12, 24, 36, 48 h according to the results of MTT assay; the expression of ERK 1/2, JNK, p38 kinases of MAPK pathway in SH-SY5Y at protein levels was measured by Western blotting.

Results
The expression of α3nAChR mRNA(0.04 ± 0.03) and protein (12.0 ± 2.5) in α3nAChR silence group was decreased significantly compared with those of control group (1.00 ± 0.11, 100.0±11.3, t = 24.58, 28.80, all P 0.05). The increased expression of phospho- p38 was detected in control group at time points 24, 36 and 48 h (120.33 ± 4.51, 122.00 ± 7.55, 119.67 ± 7.57) compared to 0 h in the same groups (100.00 ± 0.00, all P 0.05).

Conclusion

GENERAL Aniline & Film just prior to the opening of the World Chemical Conclave in New York, questionnaired its professional employees with the idea of developing a composite picture of what a scientist is like. We do not know what the results prove, or that they prove anything particularly, but they do make interesting reading. The questionnaire contained 20 main questions and a like number of subordinate queries. The entire quiz was anonymous and the response was very high—90%. To keep the record straight we should report that in the quiz were engineers and physicists, but the majority were chemists. Of those questionnaired about 45% hold Ph.D. degrees, 43% have B.S.'s, and 12% write M.S. after their names. The typical American scientist, according to the General Aniline survey, is just under 35 years of age, is 5 feet 9 inches tall, weighs about 160 pounds, has blue or brown eyes and brown hair, ...


The latest technical solutions provide new opportunities for reducing energy consumption in electrified transport systems. The basic solution is to eliminate vehicles based on resistor start-up system and replace them with vehicles equipped with semiconductor based converter propulsion system (choppers and voltage source inverters). This type of drive also allows to recover energy (recuperation) from train braking, which is repeated very often case of metro lines. The problem is to find the receiver for this energy while the vehicle is braking. Large opportunities are also available when using various types of energy storage devices: stationary installed on the side of traction line and mobile ones used on-board the traction vehicles. Choosing the type of energy storage device for operating conditions, their capacity and the location of installation are complex optimization processes. This type of solution involves significant financial input, which reimbursement is spread over a long period of time. Therefore, it seems rational to seek solutions with limited financial outlay. This paper presents a solution analysis of adjusting the timetable and timeshifts between vehicle streams on the metro line to increase the efficiency of energy recovery of regenerative braking vehicles. This operation will reduce the amount of energy consumption by vehicles from the traction substations. The results presented in the paper were obtained by computer simulation of operation on the first line of the Warsaw subway, assuming that there was no energy storage devices and traction substations were operating without recuperation of the energy to the power system.


Suspension systems are designed for the increase in
comfort and stability in vehicles while driving. Parameter changes
in these systems affect overall performance. Researchers are
continuously working on the performance enhancement of
suspension systems by designing dampers of variable damping
coefficient. In this research work a quarter car model suspension
system was developed to demonstrate experimentally the influence
of changing the damping coefficient, the stiffness, and the loading
level to fully understand the allowable combination of parameters
for a smoother ride. A variety of different test scenarios are
implemented to the system to observe the variations in damping
ratio. The damping ratio of the system found to be dependent on
the design of the opening mechanism.The valve opening methods
can give different results with the same parameters.


In this research, the use of digital evidence in courts is studied. State administrators, including the executive and the legislative, must use information technology (e-government), especially the judiciary. Digital evidence is also frequently utilised to resolve administrative disputes between states. Judges should be able to look over and evaluate cases that involve digital evidence in order to do this. The Supreme Court has issued PERMA Number 1 of 2019 concerning the Electronic Administration of Cases and Trials in Courts in order to get ready to adapt to changes in the digitalization of electronic services (e-government). This time, the Supreme Court is taking reforming the justice system's information technology field seriously as seen by the E-Court. Administrative Court Judges can make an effort, but in the digital age, Administrative Judges must pay attention to the entire e-government system. For instance, licencing now involves an integrated online system that includes components of the regional government, the provincial government, and the government centre. These factors make it possible for administrative judges to consult with web professionals. Because it is virtually difficult for an administrative judge to have good and accurate understanding of digital forensics, digital web forensic experts are required when proving matters at the Administrative Court. Web-based experts will provide insight into a case, assisting State Administrative judges in making judgements. The Supreme Court should hold education and training regarding online licensing, online registration, and online validation carried out by the executive. Administrative judges should not hesitate to present web expert witnesses to explain an administrative case.


Objective To detect the expression of basic fibroblast growth factor (bFGF)-transfected bone marrow mesenchymal stem cells (MSC) and the effect on the expression of transforming growth factor-beta1(TGF-β1) mRNA in focal cerebral ischemia/reperfusion (MCAO/R) rats.Methods MSCs were transfected with bFGF gene using electro-perforation technique.Immunohistochemisty and dual labeling technique were used to identify the bFGF expression;RT-PCR technique was used to detect the expression of TGF-β1 mRNA.Results bFGF-transfected MSCs could continuously express products 1 and 2 weeks later after transplantation.In the MSCs transplantation groups,compared with the MSCs transplantation group (0.42± 0.04 vs 0.52± 0.06), there was a lowest expression of TGF-β1 mRNA in the bFGF-transfected MSCs transplantation groups (0.33± 0.05, 0.36± 0.04), (P 0.01). Conclusion bFGF-transfected MSCs express bFGF gene and significantly down-regulate the expression of TGF-β1 mRNA in ischemic brain after transplantation.


CURRENT SCIENCE, VOL. 113, NO. 10, 25 NOVEMBER 2017 1832 A critical and comparative study of recently collected specimens (available at CSIR-NBRI Herbarium (LWG)) with type specimens and description revealed that thalli are less wide at apex in our specimens compared to type specimens, i.e. 6–11(13) mm wide at apex and smaller size of pseudoelaters compared to type specimens (139–190 m long), which may be due to changes in climatic and ecological conditions over a long period of time. A. macrosporus resembles A. punctatus L., A. pandei Udar & A. K. Asthana and A. crectus Kashyap in some features, especially the morphoform of thalli, but can be clearly recognized by its characteristic sporoderm architecture. In A. punctatus sporoderm is reticulate, rather pitted; A. pandei is clearly distinctive in having smaller spores (39–45 m) with verrucate to lamellate sculpturing, while A. erectus can be distinguished by reticulate sporoderm pattern with spinulate ridges enclosing irregularly shaped lumeni. Of the seven locations (five in Maharashtra and one each in Tamil Nadu and Gujarat) where A. macrosporus has been located in the country so far, the species could never be collected again from its type locality at Borghat in Maharashtra and Kodaikanal in Tamil Nadu. As such, the species is presently known from severely fragmented populations at only five inferred sites spread across Maharashtra and Gujarat with an 'extent of occurrence' of much less than 5000 km and a highly restricted 'area of occupancy'. Therefore, as per the IUCN Red List categories and criteria version 3.1 (ref. 6), A. macrosporus belongs to endangered category [ENB1a + 2a; C2a(i)] at global level.


In the oil and gas industry, internal corrosion of carbon steel is commonly encountered during production and transportation of hydrocarbons and water saturated with corrosive gases such as CO2 and H2S, with CO2 corrosion (termed sweet corrosion) the most common one.
This thesis presents an experimental and modelling approach to study the effect of surface roughness on the mass transfer and corrosion of carbon steel.
The influence of surface roughness on mass transfer on a rotating cylinder electrode apparatus is investigated experimentally. Mass transfer from four different samples, with roughness values of 0.5, 6, 20 and 34 μm, is measured using the limiting current technique for a range of rotational speeds in NaCl solutions saturated with N2 at pH=3 and 4. A new correlation for Sherwood number as a function of the Reynolds number, Schmidt number and surface roughness is proposed. Complementary experiments in CO2 environments were used to assess the combined limiting current associated with H+ and H2CO3 reduction. In the CO2 environments considered, surface roughness is found to have no significant influence on the limiting current contribution from H2CO3, which can therefore be determined from Vetter's correlation.
Novel surface pH measurement methods are also developed to measure surface pH. These were implemented to study the surface pH during CO2 corrosion. Comparisons between mesh capped probes and iridium oxide probes showed that the results in both cases were very similar.
Two mechanistic models were implemented to predict corrosion rates in the CO2 environments. The models were validated against the experimental results from both the literature and the current study. The first, multi-node model is used to predict the concentration of species within the boundary layer. While, the second, two-node model was used to explore the effect of roughness in the CO2 environment. Agreement between experimental and theoretical corrosion rates was good and demonstrated clearly how increased surface roughness accentuates corrosion rates and mass transfer coefficients, and that the latter need to be accounted when implementing theoretical models.


Magnetic soils confound both magnetometers and electromagnetic induction (EMI) sensors when these sensors are being used to detect landmines and unexploded ordnance (UXO). The amplitude of the magnetic susceptibility of the target is the problematic physical characteristic for magnetic detection; whereas the variation of magnetic susceptibility as a function of frequency, or magnetic viscosity, is the problematic physical characteristic that limits EMI sensor's effectiveness for target detection. Quantifying the physical characteristics of the soils in which targets are located can potentially provide insight into new methods of detection. Two new production sensors, which measure magnetic susceptibility as a function of frequency, have been tested on paramagnetic salts and soil samples from sites that exhibit magnetic viscosity. The purpose was to document their response for comparison with other popular sensors such as the Bartington MS2 system or the Quantum Designs MPMS. One of the new sensors, the SM-100 sensor from ZH Instruments, measures magnetic susceptibility at five fixed frequencies (~400Hz - 8 kHz) and six field strengths (10-320 A/m). The MAGNASAT sensor, a recently developed tool from Queensland Magnetic Research, can measure over a wider frequency band (10 Hz to 100 kHz) at a single field strength (80 A/m). The MAGNASAT measures the both the real and complex components of the magnetic susceptibility, whereas the SM-100 only measures the real component. Both sensors are sensitive enough to measure diamagnetic materials such as water, however, which is useful in field settings.


Ferreres et al. hypothesized that over-reduction of the capitate on the lunate during four-corner fusion would stretch the extrinsic volar wrist ligaments, resulting in post-operative radial deviation posture of the wrist (1). The objective of this study was to examine the effect of altering the capito-lunate relationship on coronalplane wrist motion after simulated scaphoidectomy and 4CF. We hypothesized that wrist resting posture and radial-ulnar motion would be altered following simulated fusion in an over-reduced position when compared to normal wrists.


Adaptive modulation and coding (AMC) and automatic repeat request (ARQ) protocol are powerful techniques for improving the spectral efficiency (SE) or the error performance in wireless packet networks over fading channels. In this paper, we first consider a discrete-rate M-QAM based AMC scheme and propose a variable power transmission scheme for transmission of packets over block-fading wireless channels. Considering the error-correcting capability of the truncated-ARQ, which depends on the maximum number of retransmissions (Nr), we then optimize the AMC and power control schemes that guarantee the required packet loss rate (PLR) performance while satisfying an average transmit power constraint. Numerical results reveal that in wireless packet systems with limited packet length, the proposed link adaptation algorithm improves the system performance in terms of the SE and the PLR However, this improvement depends on the target PLR and Nr When the target PLR is sufficiently small, this improvement will be observed in terms of the SE for small Np however, in the larger target PLR, the improvement will only be observed in terms of the achievable PLR.


Drawing upon the theory of responsive regulation, in the 1990's the Australian Commissioner of Taxation expressed the partnership model of tax administration. Shortly afterwards, the New Zealand Inland Revenue Commissioner joined this shift, to what has been caste as, the way forward in meeting the demands upon a tax administration in a modern, open democratic society. After something like a decade since the adoption of this new model of tax administration, it is appropriate to review its history, the challenges that have been encountered and also to reflect upon the prospects of the partnership model. The purpose of this paper is to undertake this task and to suggest avenues for further critical reflection upon the operation of the partnership model with a view to its enhancement.The first part of this paper identifies and elaborates upon the two models of tax administration that are evident in the recent Australian and New Zealand history – the adversarial model and the partnership model. The second part of the paper reviews the drivers which prompted the paradigm shift in New Zealand and Australia from an adversarial model to a partnership model. The third part of the paper identifies tensions within the partnership model and discusses the practical emanations of these tensions, evident in the operation of the partnership model.

Objective To investigate the effect of Butorphanol Tartrate Injection combined with propofol for colonoscopy in elderly patients.Methods Sixty elderly patients patients(ASA Ⅱ~Ⅲ,65 years old) undergoing colonoscopy were recruited in this study.Patients were randomly divided into 2 groups: Fentanyl group(group F) or Butorphanol Tartrate group(group N),Compare and analyze the blood pressure,heart rate,respiratory rate,the incidence of hypoxemia just before(T0),at 1 minute(T1),2 minute(T2),5 minute(T3) between the two groups.Recovery time,time to leave the hospital,the incidence of postoperative abdominal pain,dizziness,nausea,vomiting,the rate of satisfaction with colonoscopy were also recorded.Results There was no significance of the blood pressure,heart rate,respiratory rate at T0,T1,T2,T3 and recovery time,time to leave the hospital,the incidence of nausea,vomiting between the two groups(P0.05).The incidence of hypoxemia and postoperative abdominal pain,in group F was significantly higher than that of group N(P0.05),but the incidence of dizziness and the rate of satisfaction with colonoscopy were lower that of group N(P0.05).Conclusion The effect of Butorphanol Tartrate Injection combined with propofol was better than Fentanyl combined with propofol for colonoscopy in elderly patients.


Background. Under the influence of combined interference, the effectiveness of radar performance significantly deteriorates. This is preconditioned by decorrelation of active noise interference by passive one that has a spatially distributed spectrum. To reduce the influence of passive interference on the active interference compensation process, it is necessary in one way or another to form a classified training sample generated only by the active interference and to assess the possible losses that arise with this case. Objective. The aim of the paper is to estimate losses for the case of adaptive spatial filtering of the active component of combined interference in the frequency method of generating a classified training sample. Methods. Analytical method of losses estimation simultaneously with the method of simulation. Results. The estimation of losses in compensation of active interference arising for different values of the base and the width of the interference spectrum coming from different angular directions has been made. The losses have been estimated which were preconditioned with introduction of notch filters in the chain for forming the weight factor of the autocompensator are estimated. Conclusions. The scientific novelty is the possibility to estimate the losses in active interference compensation in spatial signal filtering using the frequency method of classified training sample generation. The practical significance is to provide the possibility to choose parameters of the jamming system when designing the radar.


This thesis consists of two papers considering different aspects of stochastic process modelling and the minimisation of computational cost. In the first paper, we analyse statistical signal properties and develop a Gaussian pro- cess model for scenarios with a moving receiver in a scattering environment, as in Clarke's model, with the generalisation that noise is introduced through scatterers randomly flip- ping on and off as a function of time. The Gaussian process model is developed by extracting mean and covariance properties from the Multipath Fading Channel model (MFC) through coarse graining. That is, we verify that under certain assumptions, signal realisations of the MFC model converge to a Gaussian process and thereafter compute the Gaussian process' covariance matrix, which is needed to construct Gaussian process signal realisations. The obtained Gaussian process model is under certain assumptions less computationally costly, containing more channel information and having very similar signal properties to its corresponding MFC model. We also study the problem of fitting our model's flip rate and scatterer density to measured signal data. The second paper generalises a multilevel Forward Euler Monte Carlo method intro- duced by Giles [1] for the approximation of expected values depending on the solution to an Ito stochastic differential equation. Giles work [1] proposed and analysed a Forward Euler Multilevel Monte Carlo method based on realsiations on a hierarchy of uniform time discretisations and a coarse graining based control variates idea to reduce the computa- tional effort required by a standard single level Forward Euler Monte Carlo method. This work introduces an adaptive hierarchy of non uniform time discretisations generated by adaptive algorithms developed by Moon et al. [3, 2]. These adaptive algorithms apply either deterministic time steps or stochastic time steps and are based on a posteriori error expansions first developed by Szepessy et al. [4]. Under sufficient regularity conditions, our numerical results, which include one case with singular drift and one with stopped dif- fusion, exhibit savings in the computational cost to achieve an accuracy of O(T ol), from O(T ol−3 ) to O (log (T ol) /T ol)2 . We also include an analysis of a simplified version of the adaptive algorithm for which we prove similar accuracy and computational cost results.

Abstract Advanced control and optimization of extraction processes are very important in the field of chemical engineering for the development of processes arising in high yield with minimal costs of time and energy. The main contributions of the current study lie in the following aspects: the first deals with the experimental study of hydrodistillation extraction method performed on a medicinal plant (Marrubium vulgare L.) as well as the optimization of the different parameters influencing the extraction yield, such as heating, drying and grinding the plant and solvent to solid ratio, in order to determine the operating conditions favorable to the realization of the extraction process, resulting in high yield, the second phase is dependent on the first, which is devoted to the mathematical modeling by exploiting three models from the literature. Furthermore, the parameters estimation of the kinetic models was carried out using genetic algorithms. The obtained coefficients of correlation and the root mean square error, show that predicted and experimental data were in good agreement.


The rate-determining ionic dissociation RX→R + +X - for S N l reactions in a polar solvent is examined theoretically. These unimolecular dissociations involve critical and extensive solvent stabilization of the ionic state compared to the covalent state to induce an electronic curve crossing to allow the heterolysis. Our approach is via a nonlinear Schrodinger equation theory recently develop to account for the mutual influence of solute electronic structure and solvent polarization-both equilibrium and nonequilibrium


The performance of a optical component is greatly dependent on its surfaces. There are many ways to measure and evaluate a surface so far, but actually no one knows exactly what a "real" surface likes, and thus makes some measurement unexplainable. This paper develops a way to construct various synthetic surfaces. Referred to actual AFM measurement, regular or irregular surfaces can be created and studied. Bumps, scratches, granules, profile errors and other construction elements can be added to form a very complicated virtual surface. The number, size and distribution of these elements can be changed, and if necessary, the surface roughness can be controlled in a specialized range. As these surfaces are created synthetically, we know exactly what construction these surface contain. The height data of created virtual surfaces can be transferred into the file that AFM instrument can read and handle. As a typical example, a very complicated surface is created step by step in this paper, and its PSD for each step are calculated. This process mikes it very clear how the surface component element affect its PSD function, and is benefit to our better understanding of real surface construction.

"Most people think that an insurance company's business is to make money out of insuring things. They are wrong. Its business is to take as much money off the public as possible, invest it successfully and hope that the conditions on which it was taken never happen."The Economist, April 13, 1974 (p. 119) In order to motivate the series of Monte Carlo simulations we have carried out in the following article we would like readers to imagine that a small rural casualty insurance company, the Farm Fire and Flood Damage Ins. Co. (FFFDIC), is to be bought by an entrepreneur (whom we shall designate by EP) provided his consulting actuary (the author of this article) can satisfy his requirements which are as follow: (i) A 15-year investment is foreseen at the end of which time EP wishes to be able to sell, hopefully without loss. (ii) The risk-capital is to be invested and (although some of it must be in easily liquidable securities) should yield a rate of return comparable with that obtainable on the same amount of capital invested in the market. (iii) The premiums will not have risk-loadings, as such, but will be loaded for profit by 15%. (iv) The risk-capital should, on the average, be returnable at the end of the 15-year investment.


Concept drift is the phenomenon where the data distribution in a data stream changes over time. It is a ubiquitous problem in the real-world, for example, a traffic accident would cause a jam in a certain period, leading to a distribution change in traffic speed. Most research in the concept drift field focuses on single data stream, however, few of them consider multi-stream environments which are more in line with the application needs. To fill this gap, we propose a multi-stream prediction setting and a multi-stream concept drift self-adaptation framework using graph neural network, named SAGN. In SAGN, we reconsider the learning procedure of GNN-based predictors from an aspect of concept drift adaptation for multi-stream. By this design, the prediction task is converted into online streaming data tasks in sub-graphs. Each sub-graph corresponds to an adaptation target and will be updated over time. In this way, locally we can overcome drift in each sub-graph by a designed adaptation technique, and globally the correlation between different data streams is well-preserved as a graph structure. Therefore, whether drift occurs or not, in one or several streams, SAGN can provide consistently accurate prediction results. We comprehensively tested SAGN on both synthetic and real-world, drift and non-drift data in the multi-step prediction task. The experiment results show that SAGN is able to achieve state-of-the-art performance in most cases.


This paper discusses a workforce development case study undertaken by TAFE [South Australia] SA Regional Institute between 2010 and 2013. This case study is informing a doctoral study at Flinders University which is investigating the unique characteristics of vocational education and training (VET) teaching, the skills that VET teaching staff must have, and how those skills are to be acquired to enable teachers to transition from novice to advanced practice. This doctoral study builds on a range of studies of the VET practitioner in the previous decade including Mitchell (2009) and Wheelahan (2010) and investigates how practice-based education theory and research and workplace learning may assist in understanding effective ways of providing professional development for teaching staff.


Twelve grossly obese patients who weighed 121 ± 22 kg (mean ± s.d.) had a free‐floating 600 ml spherical intragastric balloon inserted per ‐oesophagus and have been followed for 12·24 months. Nine patients lost up to 21 kg (11 ± 6·4 kg) over 3 months after which they reached a plateau and then regained weight so that by 1 year only one patient had maintained her weight loss. Three patients could not tolerate the balloon owing to complete reflex inhibition of gastric emptying. Such marginal and temporary weight loss is of no value in the treatment of gross obesity.


Abstract Representatives of Slrepiomyces strains isolated from environmental soil samples were subjected to identify for the diagnostic characters recommended by Williams et al. (1983b) as a duplicate. Diagnostic characters were tested using a mixture of spores and mycelial fragments, respectively, in order to identify some Streptomyces species and strains on computer assited identification. Most of the marker strains were identified to the correct clusters. In contrast, 20 strains out of 38 unknown strains were assigned to any major cluster described by Williams et al. (1983a). Computer‐assisted identification procedure has provided reliable identification scores for marker or unknown strains.


1In Optical Wireless Communication (OWC), the use of narrow beams can enhance the achievable bit rates and reduces interference. However, this requires a mechanism to find the direction in which the transmitter must send its beam towards the receiver. It turns out that it may be counterproductive to widen the beam during the direction search phase. This paper analyzes a system with a feedback loop that allows the receiver to report back, once it sees an incoming signal. However, this feedback channel may not have a high time resolution and may have a relatively long and random delay. This paper studies the appropriate beam width adaptation during direction search and acquisition, taking into account the received (electrical) energy per bit, and noise limitations of the transimpedance amplifier. The paper also introduces a new address coding scheme. It uses continuous addressing, thereby eliminating overhead from packet headers, error correction coding or synchronisation words, by adopting maximum-length Linear Feedback Shift Register sequences. This accelerates the beam direction search.


We present a method to detect quantum memory in a non-Markovian process. We call a process Markovian when the environment does not provide a memory that retains correlations across different system-environment interactions. We define two types of non-Markovian processes, depending on the required memory being classical or quantum. We formalise this distinction using the process matrix formalism, through which a process is represented as a multipartite state. Within this formalism, a test for entanglement in a state can be mapped to a test for quantum memory in the corresponding process. This allows us to apply separability criteria and entanglement witnesses to the detection of quantum memory. We demonstrate the method in a simple model where both system and environment are single interacting qubits and map the parameters that lead to quantum memory. As with entanglement witnesses, our method of witnessing quantum memory provides a versatile experimental tool for open quantum systems.


Distributed event system(DES) is a kind of complex system that works with distributed asynchronous and concurrent properties.There are many instances of DES in communication,manufacturing and information industries,so it is important to build a DES model to describe their behavior.Object oriented Petri net(OOPN) which combines the concepts of Petri nets and object oriented technoloy is very useful in analyzing the DES.To involve much information in the net,a new approach, message driven object oriented Petri nets(MOPN),was defined,and its properties were introduced.A model of FMS,which is a kind of typical DES,was given as an example.


Objective To investigate the expressions of O6- methylguanine- DNA methyl- transferase( MGMT) and DAN topoisomeraseⅡ alphassion( Topo- Ⅱα) in human gliomas and the correlations between its expressions of the two proteins and the drug sensitivity of three kinds of common chemotherapeutics. It is helpful to provide rational and effectual conduct in the clinical personalized chemotherapy. Methods We collected 55 fresh human glioma specimens. The glioma tissues were taken in the neurosurgical operations and were sent to ordinary pathology,immunohistochemical detection of the expression of MGMT and Topo- Ⅱα protein as well as in vitro drug sensitivity test simultaneously. MTT assay was used to detect the chemosensitivity of three common central nervous systematic chemotherapeutics as ACNU,TMZ and VM- 26 under the antitumor drugs- peak plasma concentration. And the statistical software SPSS 17. 0 was utilized to analysis the correlation among the expression of MGMT and Topo- Ⅱα and the chemosensitivity of the human brain glioma. Results The inhibition ratio,which ACNU and TMZ acted on the gliomas culture,showed a negative correlation to the expression of MGMT( r s=- 0. 781,- 0. 761,P 0. 05). On the contrary,there was no correlation between the inhibition ratio of VM- 26 and the expression of MGMT( r s= 0. 048,P 0. 05). The inhibition ratio which VM- 26 acted on the gliomas culture showed a positive correlation to the expression of Topo- Ⅱα( r s= 0. 825,P 0. 05). There was no correlations between the inhibition ratio of ACNU and TMZ and the expression of Topo- Ⅱα( r s=- 0. 116,0. 015,P 0. 05). Conclusion Making sure the expression of MGMT and Topo- Ⅱα and the in vitro chemosensitivity of common antiglioma drugs may give us important clues on the benefit of the rational choice of the appropriate personalized therapeutics of gliomas in clinical work. In this way,you can avoid abusing the invalid drugs,preventing the side- effects of these drugs and improve the long term outcomes of the glioma patients.


Wireless local area network has been a great success and is widely used to provide wireless coverage.In performance analysis,system throughput is one of the most important specifications to be considered.System throughput,especially in multi-cell WLAN,is affected by several factors.Researches on coverage overlapping,asymmetrical rejection and channel assignment are helpful for the design and optimization of WLANs.


Twenty five genotypes of cauliflower along with one check Madhuri were evaluated for yield and some yield contributing morpho physiological components in cauliflower. Further, the investigation was done to find out interrelationships among different characters and their direct and indirect contribution towards yield. Estimates of phenotypic and genotypic correlation coefficient revealed that marketable yield per plant was significantly and positively correlated with curd size index, gross weight per plant, curd solidity, curd compactness, curd diameter, stalk length, number of leaves per plant and harvest index. The high positive direct effect on marketable yield per plant was exhibited by curd size index, gross weight per plant, days to marketable curd maturity from date of transplanting, curd solidity, stalk length and per cent marketable curds. Therefore, these traits should be considered as the selection criterion to improve the marketable yield per plant.


: Lactobacillus rhamnosus GG (ATCC 53103, LGG) is one of the most researched probiotic strains in the world. It has been studied extensively in humans and experimental animals for a wide variety of uses. L. rhamnosus GG was iso-lated from an adult human in 1983, and it has a safe history of use in food products since 1990. The strain has most of the characteristics generally proposed for a good probiotic strain, including excellent survival in and transient colonization of the gastrointestinal tract, which is based on its adhesion capacity to intestinal mucus and epithelial cells. Successful recovery of the strain in stool samples has made dose-response studies possible and enabled the evaluation of effective dosing using food products. L. rhamnosus GG has also been found to have many beneficial health effects on gastrointestinal infection, antibiotic associated diarrhea, respiratory infection, viral infection and allergy.


Abstract: The Double Asteroid Redirection Test (DART) will be the first space experiment to demonstrate asteroid impact hazard mitigation by using a kinetic impactor to deflect an asteroid. DART is the interceptor element of the Asteroid Impact & Deflection Assessment mission (AIDA), a joint NASA-ESA mission which also includes the ESA Asteroid Impact Monitor rendezvous mission. The primary goal of AIDA is to measure and characterize deflection of an asteroid by a kinetic impactor. The results will have implications for planetary defense, human spaceflight, and Near-Earth Object science and resource utilization. This paper describes the mission-design and navigation proposed to impact the secondary asteroid within the Didymos binary system. This analysis includes a simulation of closed-loop proportional navigation approach, which achieves the required precision targeting in spite of a very short detection timeline and many unknown target parameters.


The aim of this study was to investigate the effect of flooring on barefoot gait according to age and gender. Two groups of healthy subjects were analyzed: the elderly adult group (EA; 10 healthy subjects) and the middl e-aged group (MA; 10 healthy subjects). Each participant was asked to walk at hi s or her preferred speed over two force plates on the following surfaces: 1) homogeneous vi nyl (HOV), 2) carpet, 3) heterogeneous vinyl (HTV) and 4) mixed (in which th e first half of the pathway was covered by HOV and the second by HTV). Two force pl ates (Kistler 9286BA) embedded in the data collection room floor measured the grou nd reaction forces and friction. The required coefficient of friction (RCOF) was analyze d. For the statistical analysis, a linear mixed-effects model for repeated measures was perfo rmed. During barefoot gait, there were differences in the RCOF among the flooring typ es during the heel contact and toeoff phases. Due to better plantar proprioception du ring barefoot gait, the EA and MA subjects were able to distinguish differences among the flooring types. Moreover, when the EA were compared with the MA subjects, differen ces could be observed in the RCOF during the toe-off phase, and gender differences in the RCOF could also be observed during the heel contact phase in barefoot gait.


Multiple register set architectures have been proposed as a method to reduce the large amount of memory traffic associated with high-level language procedure calls. In this thesis, the effect on overall processor memory traffic of multiple register sets is characterized for a set of real programs. To accomplish this, traces of programs' address and register references were collected on a VAX-11/780. These traces were then mapped to the traces that could have come from a hypothetical VAX with multiple register sets. The memory traffic for various numbers of register sets and numbers of registers per set were compared to the memory traffic in the original trace. The results show a 10-20% reduction in memory traffic using the multiple register sets; the results vary among programs. The effect of context switch was also measured and found not to be significant.
A synthetic benchmark program, Dhampstone, was written in the C language with the goal to accurately characterize program behavior with and without multiple register sets. To construct the program, existing program statistics were supplemented with measurements of I/O and C language register declarations. The change in memory traffic with multiple register sets on Dhampstone was compared to the change measured in the real programs; there was good agreement for a variety of numbers of sets and numbers of registers per set.
Multiple register sets were compared to other local memory organizations using a chip area model and a memory access time model. These organizations consisted of a variety of different cache organizations. Combinations of different caches and multiple register sets were also examined. With a small chip area, a top-of-stack cache performed better than multiple register sets. For larger chip areas, an instruction cache, or better yet, an instruction cache plus a small top-of-stack cache, perform well. At the largest cache sizes studied, a full cache is required, so that each memory reference could potentially be in the cache. Adding multiple register sets to a full cache improves performance slightly for larger chip areas.

The objective of the study is to analyze various policies, regulation and legislation regarding public debt and processes of the situation in the public finance field, to recognize key problems, propose solutions and advocate for change, with a special focus on monitoring of public finance. Often debt does not serve the needs of the citizens and puts limitations on democracy in a sense that does not imply involvement of citizens and NGOs in the process of decision making in the area of public finances and at the same time is characterized by a low level of transparency. Hence, the study will identify problems in implementation of the existing legislation or identify lack of necessary legislation. This will be the basis for proposing policy recommendations regarding monitoring of public finance for the covered countries and advocating for them. The study analyzes the recent debt trends in Bosnia and Herzegovina, Bulgaria, Kosovo, Macedonia, Montenegro, Serbia, and Slovenia with the aim of warning about possible problems with long-term debt sustainability. It is very important to detect debt vulnerabilities and to react in a timely manner.


Some time ago the author published the results of a series of experiments on the flow of water through tubes having uniformly diverging boundaries, in which the loss of energy corresponding to given angles of conicity of the tubes was determined. These pipes, some circular, others square or rectangular in cross section, had the same initial and the same final areas, these being respectively the same as those of circles of 1·5 inch and 3·0 inches diameter, the ratio of initial to final mean velocity of flow being in each case 4 to 1.


This report outlings the procedures adpoted in the development of a flood forecasting system for Alice Springs. A description of the catchment is presented and discussion of the flooding problem in Alice Springs provided. The methodology is developed. The flood forecasting model program is appended (Appendix 1).
The model uses the established parameters (X and K), the rating curves for both stations, the estimated rate of rise at Wigley Gorge and the telemetered data to predict the water level at Wills Terrace for the next hour.


Abstract: An instrument was built to measure the output fluorescence response characteristics of a 248nm KrF laser using 4mm-thick fluorescent glass as a screen. Experiments show when irradiated laser intensity is no more than 0.7J/cm2, the fluorescent response is linear. And the fluorescent spot intensity distribution was spatial coherent with the output beam profile distribution of the LPX-150. So we can use high-homogeneity optical glasses as fluorescence wavelength conversion material in beam profile measurements.


Talha b. Ubeydullah is one of the first muslims and emigrants to Medina. He was also one of the members of Shura. He took part in every battles except Battle of Badr. He was not so active at the time of Caliph Abu Bakr and Umar. On the other hand, at the time of Caliph Uthman and Ali he was very active in politics. He was accused of being passive in the events leading the martyrdom of Caliph Uthman. He was the first one who pledged allegiance to Caliph Ali but he was among the opposition side at the Event of Jamal. And he was killed during this event.

This work presents a modelling framework to enable comparison and trade-off study of different aircraft system architectures. The framework integrates a computational module to select feasible architectures with a modelling platform that simulates the power generation, distribution and fuel consumption of the aircraft as well as system-level models for the system being evaluated. Its capabilities are demonstrated for the case of the electrification of the primary flight control system (PFCS) using different electric technologies (EHA, EMA) and different levels of electrification ranging from the conventional hydraulic to the all-electric. The performances of different architectures are analysed with respect to the change in the mechanical power extracted from the engine, the weight and the fuel burn of the aircraft. The framework demonstrates the capability of evaluating multiple, different, system architectures in a way that is scalable for different systems or different aircraft. It supports a designer evaluating the aircraft-level impact of their design choice at system-level, and it can aid in assessing technology options early in the design process. © 2017 The Authors.

This paper is part of my doctoral dissertation at Stanford University. I am grateful for the advice of James G. March, William P. Barnett, and Joel Podolny, the comments of Michael T. Hannan, Pamela Haunschild, Christine Oliver, David Strang, Nancy Brandon Tuma, and anonymous reviewers for ASQ, and the editorial assistance of Linda Pike. Financial support from the Stanford Center of Organizations Research, the Norwegian School of Economics and Business Administration, the Richard D. Irwin Foundation, and the Spencer Foundation is gratefully acknowledged. This paper focuses on organizations' abandonment of strategy, which may be driven jointly by contagion qnd competition from other organizations. This paper treats both explanations but emphasizes contagion. I argue that strategy abandonment is contagious because the future performance of current and alternative strategies is highly uncertain, causing decision makers to examine the actions of other organizations in the industry for clues to the correct action. Contagion from organizations easily observed by the focal organization is stronger than contagion from other organizations, causing corporate links across markets to become important routes for the contagion of strategy abandonment. This theory is tested on a sample of radio stations abandoning a strategy and is supported by evidence that contagion of abandonment occurs through the influence of an organization's social reference groups.'


Abstract Previous studies have indicated that under hydroponic conditions, spring wheat (Triticum aestivum) plants produce higher grain yields, more tillers, and increased dry matter when continuously supplied with mixtures of NO3 and NH4 than when supplied with only NO3. The objective of this study was to determine if mixed N needs to be available before or after flowering, or continuously, in order to elicit increases in growth and yield of wheat. During vegetative development, plants of the cultivar 'Marshal' were grown in one of two nutrient solutions containing either a 100/0 or 50/50 mixture of NO3 to NH4 and, after flowering, half the plants were switched to the other solution. At physiological maturity, plants were harvested, separated into leaves, stems, roots, and grain and the dry matter and N concentration of each part determined. Yield components and the number of productive tillers were also determined. Availability of mixed N at either growth stage increased grain yield over plants receivin...


Reliable operation of transmission system is essential to obtain reliable operation of composite power system. FACTS devices are playing very significant role in improving the effectiveness of transmission system performance. IEEE 9 bus system case study is considered to investigate the reliability with and without incorporation of UPFC. IEEE 9 Bus system reliability is evaluated by developing Markov model. Selection method of specific outages, which lead to inadequacy and security problems in the system - is presented in this paper. Initial reliability indices like probability of failure and frequency of failure are obtained by Markov model. Based on these two basic indices load point and system indices are evaluated. Improvement in the reliability of IEEE9 bus system with the incorporation of UPFC is examined in the present work. The method which calculates more accurate reliability indices with lesser number of computations, within less time is proposed in the present paper.

Samples of Chernobyl fuel debris, including massive corium and "lava" were collected inside the Chernobyl "Sarcophagus" or "Shelter" in 1990, transported to Leningrad (St. Petersburg) and stored under laboratory conditions for many years. In 2011 aged samples were visually re-examined and it was confirmed that most of them remained intact, although some evidence of self-destruction and chemical alteration were clearly observed. Selected samples of corium and "lava" were affected by static leaching at temperatures of 25, 90 and 150 °C in distilled water. A normalized Pu mass loss (NLPu) from corium samples after 140 days was noted to be 0.5 g/m2 at 25 °C and 1.1 g/m2 at 90 °C. For "lava" samples NLPu was 2.2–2.3 g/m2 at 90 °C for 140 days. The formation of secondary uranyl phases on the surface of corium and "lava" samples altered at 150 °C was confirmed. The results obtained are considered as an important basis for the simulation of fuel debris aging at Fukushima Daiichi nuclear power plant (NPP).


The dawn of the Internet has created significant challenges to protecting copyrighted materials from piracy. In the past, copyright protection was mainly concerned with the threat of infringement from the sale of counterfeit goods, like pirated CDs and optical media. However, the Internet has now allowed for online piracy where infringing materials can be accessed online or copied with even greater ease. Vietnam has recently become a jurisdiction that is a hotbed for online piracy and copyright infringement globally. This is largely because Vietnam's current statutory and regulatory regime fail to effectively create an effective antipiracy regime in accordance with its WTO TRIPS obligations. Furthermore, Vietnam's recent accession of various treaties like the CPTPP and WCT further galvanizes a need for change in Vietnam's intellectual property regime. Thus far, Vietnam's attempts at fashioning an effective site-blocking regime have not succeeded. This paper will look at other effective site-blocking regimes, namely Singapore, India, and France, to look prospectively at what may be possible in Vietnam.


Abstract: The 'Online Voting System' is a web based voting platform for conducting elections online. This system seeks to use face recognition algorithm for voter identity authentication to enhance the security of the electioneering process and ultimately providing an online platform which enables all eligible voters to exercise this activity from any location. The user must sign in/login using their respective credentials and they will be logged in into the system only after the face recognition authentication is successful. Thereafter, the voter can cast their vote securely and logout of the system. Hence, this project based on Online Voting System could be used for conducting secure and fair elections online. Keywords: online voting, face detection, face recognition, authentication, django, tensorflow.js, deepface


Asians in Sweden make up over 200,000 inhabitants. However, compared to the Afro-Swedes, the Latin Americans or the minority inhabitants who have a background in the Middle East, the Swedish Asians are largely absent from the political, cultural and academic spheres in contemporary Sweden. This absence applies in both minority and migrant contexts as well as in connection with migration and integration issues. This article consists of a study of literary texts written by minority authors who themselves are not Asians and in whose works Asians appear as characters as well as an analysis of texts written by Swedish Asians who write about how both majority Swedes and minority residents view them. The purpose is to try to understand this relative absence of Asians within both minority Sweden and majority Sweden and why they are so absent in relation to contemporary Swedish race relations.

This paper presents the results of an experimental study of seabed liquefaction under progressive waves. Firstly, during preliminary tests, the physical and mechanical parameters of the soil selected as the subgrade material were determined. A series of monotonic triaxial shear tests were carried out at different initial void ratios and mean effective stresses. The susceptibility of soil samples to liquefaction was estimated. The results were used to design experiments in a wave flume. Their main purpose was to study the effect of wave height on wave-induced liquefaction. The experiments were carried out in a wave flume that is 64.1 m long, 0.6 m wide, and 1.4 m high, in a specially built experimental stand located 5.0 m from the wave generator below the flume bottom. Wave propagation was conducted over constant water depth which was equal h = 0.5 m. The wave surface elevation was measured by resistance type wave gauges. The pore-water pressure was measured by transducers located in the middle of the sediment pit, at four different soil depths. Parametric studies were carried out to investigate the influence of wave height on the liquefaction process. The results of experiments shown that pressure buildup is a strong function of the wave height and increases with increasing its value.


This paper describes a generic technique for representing Adaptive Learning Resources by extending current metadata schemas. The requirement for the work described here has grown out of the necessity to facilitate accurate discovery and integration of Adaptive Learning Resources, namely Adaptive Hypermedia Services.


Current physics-based wind turbine monitoring methods often need extra sensors installed on wind turbines, thus increasing the operation and maintenance (O&M) cost. Besides, physical methods are only effective under some constraints. The real effectiveness needs to be further checked in real conditions. Recent advances in data acquisition systems allow collection of large volumes of operational data of wind turbines. Learning knowledge from the data allows us to do monitoring in another direction. In this paper, a survey of deep learning algorithms applied to wind turbine condition monitoring is given. Compared with original data, more meaning features were extracted through feature extraction of deep learning. Monitoring these new signals, outliers were detected by applying suitable control charts. Several industrial cases confirmed the effectiveness and efficiency of these frameworks.


Medium resolution spectra of more than 400 subgiant and turn-off region stars in ω Centauri were analysed. The observations were performed at the VLT/Paranal with FORS2/MXU. In order to determine the metallicities of the sample stars, we defined a set of line indices (mostly iron) adjusted to the resolution of our spectra. The indices as determined for ω Cen were then compared to line indices from stars in the chemically homogeneous globular cluster M 55, in addition to standard stars and synthetic spectra. The uncertainties in the derived metallicities are of the order of ±0.2 dex. Our study confirms the large variations in iron abundances found on the giant branch in earlier studies (-2.2 < [Fe/H] < -0.7 dex). In addition, we studied the α-element and CN/CH abundances. Stars of different metallicity groups not only show distinct ages (Hilker et al. 2004, A&A, 422, L9), but also different behaviours in their relative abundances. The a abundances increase smoothly with increasing metallicity resulting in a flat [a/Fe] ratio over the whole observed metallicity range. The combined CN+CH abundance increases smoothly with increasing iron abundance. The most metal-rich stars are CN-enriched. In a CN vs. CH plot, though, the individual abundances divide into CN- and CH-rich branches. The large abundance variations observed in our sample of (unevolved) subgiant branch stars most probably have their origin in the pre-enriched material rather than in internal mixing effects. Together with the age spread of the different sub-populations, our findings favour the formation of ω Centauri within a more massive progenitor.
