Blood type phenotype incompatibility including Rhesus between donors and patients may result in cross-matching problems, triggering alloimmunization, and causing Hemolytic Transfusion Reaction (HTR). Rhesus blood type incompatibility between mother and fetus may cause Hemolytic Disease of Fetus and Newborn (HDFN). Pretransfusion phenotypic blood groups matching also reduce cost efficiently which means antibody screening is no longer needed. The purpose of the study was to find the proportion of Rhesus blood type phenotypes in routine blood donors at the Blood Donor Unit, Indonesian Red Cross in Bandung city, Indonesia. The study was descriptive and observational with across-sectional design. The study was done at the Blood Donor Unit, Indonesian Red Cross in Bandung city from April 2016 to September 2017. The subjects were 142 routine blood donors. Blood sampling was done simultaneously with blood donation. Rhesus antigen examination of ethylene diamine tetraacetic acid (EDTA) blood was done by gel method. Subjects characteristics were males (68%) and females (32%), with the mean age of 39 years. Examination of Rhesus antigen foundantigen D(100%), antigen e(98.6%), antigen C(97.9%), antigen c(38.7%) and antigen E(31.7%). Results of Rhesus phenotypes were DCe/DCe(61.3%), DCe/DcE(29.6%), DCe/dce(7%), DcE/DcE(1.4%) and DcE/dce(0.7%). The distribution of Rhesus blood type was affected by factors such as genetics, race, ethnicity, marriage, demography, and migration. Rhesus blood phenotypes proportion in routine blood donors at Blood Donor Unit, Indonesian Red Cross in Bandung city sorted from the most were DCe/DCe, DCe/DcE, DCe/dce, DcE/DcE, and DcE/dce.


Differential model of dynamical predator-prey system contains some factors that constitute a formal description of features of the interaction between the predator and its prey. The initial population sizes are the factors which affect the behaviour of the predator-prey interaction.
These factors may not be uniquely defined. In this paper we study the effect of uncertain initial population sizes of predator and prey on the behaviour of predator-prey interaction. Results based on numerical simulations are discussed.


We investigated the effect of atmospheric-pressure plasma (APP) and low-pressure plasma (LPP) treatments on the performance of organic light emitting diodes (OLEDs) with an indium tin oxide (ITO) layer. The Owens-Wendt and Lifshitz-van der Waals acid-base methods revealed that the increase of surface energy was mainly attributed to polar component (γ p s ) and Lewis base (γ - s ) interactions, respectively, independent of either APP or LPP treatments. Unlike APP treatment, LPP treatment more plentifully produced reactive oxygen species in the plasma. Therefore, the LPP-treated ITO surfaces slowly proceeded with reorientation compared to APP-treated ITO. The carbon content in untreated ITO was approximately 0.045%, while those of Ar APP-, Ar/O 2 APP-, and O 2 LPP-treated ITO were 0.014, 0.011, and 0.010%, respectively, mostly containing incorporated reactive oxygen. The O 2 LPP-treated surface showed more uniform roughness than Ar or Ar/O 2 APP-treated surfaces. The highest work-function (Φ) value (4.58 eV) was obtained from O 2 LPP-treated ITO, intermediate values (4.47-4.48 eV) from Ar and Ar/O 2 APP-treated ITOs, and the smallest value from untreated ITO (4.46 eV). Thus, OLED fabricated on the surface of Ο 2 LPP-treated ITO substrate exhibited superior performance among all plasma-treated samples.


Remanent magnetization curves for two samples of iron oxide particles with different size distributions were investigated. It was observed that the isothermal remanent magnetization curve and the DC demagnetization remanence curves are strongly depended on fine particle size. Moreover, it was figured out that remanent curves are quite complicated for the assembly of larger particles. In terms of remanence dependence analysis, it was shown that favourable interaction mechanism for the assembly of iron oxide particles strongly depends on particle size. The isothermal remanent magnetization curves were analysed in terms of the Stoner-Wohlfarth model. It leads to determine particle anisotropy field. It was found that the anisotropy field depends on particle size. It was assumed that observed differences related to different magnetic structure of particles.


Decisions about managed care are clear-cut--in theory. Add a trusting patient to the scenario, and they get a lot tougher.


The Learning Health Community is an emergent global multistakeholder grassroots incipient movement bonded together by a set of consensus Core Values Underlying a National‐Scale Person‐Centered Continuous Learning Health System developed at the 2012 Learning Health System (LHS) Summit. The Learning Health Community's Second LHS Summit was convened on December 8 to 9, 2016 building upon LHS efforts taking shape in order to achieve consensus on actions that, if taken, will advance LHSs and the LHS vision from what remain appealing concepts to a working reality for improving the health of individuals and populations globally. An iterative half‐year collaborative revision process following the Second LHS Summit led to the development of the Learning Health Systems Consensus Action Plan.


Robot force control is useful in industrial finishing applications such as polishing and deburring. The standard position-based force control method involves an integrator in the controller, and is usually slow in response and has stability issue. A force control method with positive feedback is proposed in this paper. Theoretical analysis and experimental results show that it has significant improvements compared with conventional integral force control method. The proposed method is implemented in a self-developed end-effector and deburring experiment is conducted on a workpiece. Results show that the performance of the robot manipulator meets the industry requirements and the outcome is more consistent compared with human operators.


2 The aim of the research was to identify the relationship between meat quality traits in pigs differing in Myf-3 and Myf-4 gene polymorphism. Such traits as pH1, electric conductivity, water holding capacity, drip loss and meat colour lightness, as well as the chemical composition of the longissimus lumborum muscle were determined. The study was carried out on 93 (47 barrows and 46 gilts) crossbred pigs (Polish Landrace × Polish Large White sows mated to Pietrain sires). All pigs were certified as NN and NN and NN Nn genotypes in respect to RYR1 gene locus. No distinct differences in meat quality traits with respect to Myf-3 or Myf-4 pig genotype influences were found. On average, the meat quality traits were in the range ascribed to normal meat quality classes. Nevertheless, the mean values of pH1 in pigs of the Myf-4 BB genotype were significantly higher (p<0.01) than in meat of AB genotype pigs (6.48 versus 6.26). Similarly, meat colour was more desirable in BB than in AB genotype pigs (p<0.05). The intramuscular fat content was very low and did not differ between gene variants.


Based on the modal assurance criterion,using simulated annealing algorithm,the dynamic characteristic data of cable-stayed bridge are extracted,optimal acceleration sensor layout scheme of main beam is obtained.According to this optimization scheme,we carry out a dynamic characteristics test on one cable-stayed bridge.The results between test data and finite element modal calculation are very closely.Theory technique research and field modal test demonstrated that the simulated annealing algorithm based on modal assurance criterion is effective and viable for optimal acceleration sensors placement of cable-stayed bridge.

Accumulators charged by means of Solar cell arrays are exposed to overcharge problems because of the uncontrolled source of the energy, the Sun. These problems are described and discussed and several solutions are outlined. A simple and rather useful solution, for the abovementioned problem, is given for certain terrestrial systems. This charging control system is described in details as it is applied to operational systems in which accumulators play an important role as electric energy sources.


AbstractTo examine the effectiveness of application of a static magnetic field (SMF) in reducing pain associated with frozen shoulder, a pathophysiological study of shoulder pain was performed using thermography and deep body thermometry in conjunction with the patients' subjective and objective symptoms. A total of 40 patients (18 men and 22 women; age range, 27 to 83 years; mean age, 57.3 years) with pain associated with frozen shoulder for a duration of 1 week to 36 years (mean, 7 years) were investigated. The subjective and objective symptoms were evaluated with inspection and palpation in conjunction with a visual analogue scale. Patients were randomly assigned to be exposed to active or dummy magnets in a doubleblind test. Active magnets [Ferrite Magnets (130 ± 10 mT, 15 mm in diameter and 7.2 mm in height)] were applied externally to the painful area. In other patients, dummy magnets (0 mT) were applied externally as a placebo. All patients wore 12 pieces of active or dummy magnets for 3 weeks, aft...


The concentration of creatinine in serum is the most widely used and commonly accepted measure of renal function in clinical medicine. Reference values of biochemical variables specific for sportsmen have never been defined, and those used for the general population are also applied to athletes. The common reference interval for creatinine in the general population corresponds to 62–115 μmol/L (0.7–1.3 mg/dL) for adult males (1). In our experience with athletes, we frequently observed high creatinine values, near or higher than 115 μmol/L (1.3 mg/dL). We studied 220 elite athletes: 15 triathletes of the Italian National Team, 29 basketball players of an Italian First Division team, 35 cyclists from 2 professional teams, 13 racing motorcyclists of a professional team, 27 soccer players of an Italian First Division team, 23 sailors of an America's …


One of the key parameters to properly and accurately assess an energy storage system is the energy efficiency, which has a direct impact on the system performance and an indirect impact in its cost. In this paper, a methodology for comparing double-layer capacitors (EDLC) and kinetic energy storage systems (KESS) in terms of energy efficiency is proposed. This methodology, based on accurate loss models, takes real operating cycles into account, so a realistic result is obtained for each particular case. An accurate study of the losses of both technologies is accomplished during the paper, getting a complete model for EDLCs and KESSs, and obtaining efficiency maps for the whole range of operation points. Some conclusions about the convenience to use one or the other alternative and the best way to operate them are presented. In addition, a specific study case related to a wave energy power generation plant has been carried out in this paper, defining a methodology to select the energy storage requirements, calculating the round-trip efficiency and getting some recommendations related to the most appropriate operation strategy to take the most advantage of the energy storage system.


Palette re-ordering is a well known and very effective approach for improving the compression of color-indexed images. If the spatial distribution of the indexes in the image is smooth, greater compression ratios may be obtained. As known, obtaining an optimal re-indexing scheme is not a simple problem. In this paper we provide a novel algorithm for palette re-ordering problem showing the advantages of using a neural network instead of classical heuristic methods. We propose to apply the Motor Map neural network which is considered an extension of the well-known SOM Kohonen neural network. Experiments confirm the effectiveness of the proposed technique.


Mandated severance benefits have been the focus of much analysis, motivated largely by firing cost concerns. Less attention has been paid to voluntary systems, as in the U.S., although theory would suggest that these too induce firing costs. In a voluntary system, of course, benefit generosity is likely to be limited, unless firing cost distortions are modest or job displacement insurance is unusually valuable. Bureau of Labor Statistics (BLS) surveys indicate that approximately one-quarter of the U.S. workforce is covered by a severance pay plan, but the BLS does not systematically collect information on program generosity. We are instead forced to rely on private surveys by associations, management consulting firms, and others for plan descriptions. Although differing in sample and survey instrument design, these studies reveal remarkable uniformity of the basic benefit formula over the last half-century, with most plans offering scheduled benefits equal to a specified number of weekly wage payments for each year of service up to a service or benefit maximum. This benefit algorithm, similar to those in many mandated plans worldwide, mimics well-established empirical regularities in job displacement losses. The benefits however are modest. The modal private plan offers one week of pay per year of service for all but the highest levels of management, perhaps one-fourth of average capital losses from a job displacement.


AIM: To compare the cytotoxic effect of evodiamine with chemotherapy drugs on A375-S2 cells, and to examine the relationship between the effects of PKC and ERK on evodiamine-induced cell death. METHODS: MTT assay and Western blot analysis were applied. RESULTS: Compared to actinomycin D, cisplatin and 5-FU, evodiamine showed less cytotoxic effects on A375-S2 cells, but it induced more significant inhibition of proliferation in A375-S2 cells incubated with evodiamine for 24 h, followed by continuous culture in drug-free medium. The activation of PKC induced by 10 μg·L -1 PMA partially blocked evodiamine-induced cell death, which was reversed by PKC and ERK inhibitors. Moreover, evodiamine down-regulated the expressions of ERK and phosphorylated ERK. CONCLUSION: Evodiamine has a strong inhibitory influence on proliferation of A375-S2 cells, even after removal of evodiamine. Evodiamine blocks the protective role of ERK to A375-S2 cells through the downregulation of ERK and phosphorylated ERK expression. [


When rain falls on undeveloped land in temperate climate zones, most of the water will soak into the topsoil and slowly make its way to the nearest receiving water body (via subsurface flow). A small portion of rainfall in undeveloped catchments, generally 10-20%, will become direct surface runoff and most of this will be generated by only a few intense rainfall events a year (The Parliament of the Commonwealth of Australia 2002; Argue 2004; Department of Environment 2004). The same types of processes occur in all areas of Australia; however, the degree of infiltration and surface runoff will vary. Runoff moves slowly through catchments because the ground surface is rough due to the presence of vegetation, rocks and soil. Small rainfall events have little impact on flow rates in surface water bodies because the major movement of water to receiving water bodies is through subsurface flow (Walsh et al. 2004).


Eleven ferrocenium halogenopentelides (P, As, Sb, or Bi) have been prepared by the reaction of a group 5 element halide with ferrocene in an organic solvent; the structure of one of the products, [Fe(η5-C5H5)2][BiCl4], determined by X-ray crystallography, reveals an extended, one-dimensional anion of irregular, edgesharing BiCl63– octahedra.


Objective To observe the expression of MMP-1 on the injury of chondrocytes in vitro induced by nivalenol.Method Human chondrocytes cultured in vitro were treated with different concentrations of NIV(0.025,0.1,0.5 mg·L-1)for 5 days.MMP-1 mRNA was determined by reverse transcriptase polymerase chain reaction(RT-PCR).The levels of MMP-1 in culture media were measured by enzyme-linked immunosorbent assay(ELISA).Results Overexpression of MMP-1 mRNA was detected in NIV toxin treated cells.The levels of MMP-1 in NIV treated culture media were higher than those in normal control group.Conclusion NIV toxin can enhance MMP-1 synthesis,which may play an important role in the injury of chondrocytes in vitro induced by NIV.

The Moraxella catarrhalis IgD‐binding protein (MID) has a unique specificity for human IgD, and the sequence with maximal IgD binding is located within the amino acids MID962–1200. In the present paper, we examined the MID binding site on IgD using a series of recombinant Ig. Full‐length IgD, IgD F(ab')2, and an IgD F(ab') C290R mutant lacking the inter‐heavy‐chain cysteine 290 were manufactured. Furthermore, a series of IgD/IgG chimeras were constructed. ELISA, dot blot and flow cytometry were used to study the binding of purified Ig to native MID, recombinant MID962–1200 or to Moraxella with or without MID. MID962–1200 bound both the IgD F(ab')2 and F(ab') C290R, indicating that the binding occurred independently of antibody structure. When amino acids 157–224 of the IgD CH1 region were substituted with IgG sequences, binding by M. catarrhalis or recombinant MID962–1200 was abolished. Subsequent smaller substitutions of IgD CH1 157–224 with IgG sequences led us to conclude that IgD CH1 amino acids 198–206 were crucial for the interaction between MID and IgD.


Crossbred beef-breed heifers, when supplied with 0.3 mg. melengestrol acetate (MGA) per head per day in the feed for 140 days as the agent for control of estrus, gained significantly (P<.01) faster (21%) and made 11% more efficient use of their feed than heifers receiving the same feed without MGA. Seven instances of estrus occurred in the 32 MGA-treated animals. One estrus occurred during the final two-day MGA withdrawal period. The control heifers continued to cycle during the experiment.

Carcass quality, as reflected in the marbling and grade scores, was not influenced by MGA. External and internal carcass fat did not appear to differ between the treated and untreated animals. Dressing percent was not affected.

MGA-treated heifers had heavier ovaries, but the total number of Graafian follicles was not significantly increased over controls. Follicles 12 mm. and larger were more numerous (P<.01) in the MGA groups. Sixteen of the 32 treated heifers had from two to five follicles each which were 12 mm. or larger.


Abstract: We studied specimens of the genus Leptobrachella Smith, 1925 collected from West Kalimantan, Indonesian part of the island of Borneo, and housed in the Bogor Museum as L. mjobergi Smith, 1925. Our morphological examination proved that the specimens should be identified as L. juliandringi Eto, Matsui et Nishikawa 2015. This is the first record of L. juliandringi from outside Sarawak, Malaysian Borneo. Brief discussion is made on the distribution of the genus in Borneo.


The gene defender against apoptotic death (DAD-1) prevents programmed cell death in animal cells. We investigated the expression pattern of DAD-1 in petals of iris (Iris x hollandica cv. Blue Magic) and carnation (Dianthus caryophyllus cv. Etarro). DAD-1 expression in Iris petals was strongly reduced by the time of visible senescence, which occurs 4 days after flower opening. Microscopic analysis showed that most mesophyll cells had died prior to a clear decrease in DAD-1 expression and that epidermis cells started to die by that time. In carnation petals DAD-1 expression also decreased by the time of massive cell death. After ethylene treatment, DAD-1 expression in carnation again decreased concomitant with the advance in massive cell death. In conclusion, DAD-1 is not an early regulator of petal cell death. Its expression may be required for the programmed dismantling of cells, as it ceases only just prior to, or concomitant with, cell death.


This paper presents a three‐dimensional(3D) volumetric display system utilizing a rotating light‐emitting diode (LED) array panel, which provides viewers with true depth cues, binocular parallax, accommodation and convergence, etc., and can be observed from any directions horizontally without the need of any special viewing aids. An experimental display system which can provide more than 8 million voxels in a cylinder display space has been developed. Now a new system that uses small size, high brightness, full color SMD LEDs as voxels and can provide at most more than 200 million voxels with a diameter of 800mm and a height of 640mm cylinder display space is being implemented.


Coherence and Rhythm : A Historical Survey on Standardization of Russian Writing ; ; The transition to modem Russian prose in the late eighteenth century is accompanied by a general reform of text and sentence rhythm. The paper deals with the intellectual prose of Nikolaj Karamzin ( 1766-1826) whose reform focused on the rhythm of the prose, both artistic and intellectual.


In the previous chapter it was shown that hedonic wage-risk studies, by assuming individuals correctly calculate their job-related risks of death, yield MVS estimates which are biased and inconsistent. Further, it was noted that in order to measure a person's perceptions of risk, and hence estimate subjective evaluations of risk reduction, the refinement of survey techniques is worthy of greater attention. In this chapter another potential bias, which may be inherent in hedonic wage-risk methods, is explored and is offered as another justification for using the contingent valuation approach in estimating evaluations of safety. The bias in hedonic wage-risk studies described here stems from a potential violation of the assumption that the labor market operates freely and is in equilibrium. When this assumption is violated, the labor market is said to experience structural constraints. Such constraints on the labor market can be shown diagramatically to render a situation in which the hedonic wage gradient is not tangent to workers' indifference curves as was the case in Figure 2.4. Rather, at an observed market level of risk and wages, the worker's maximum level of expected utility intersects the hedonic wage gradient. That the hedonic wage gradient may be comprised of a locus of indifference curve intersections rather than tangencies, suggests that a "wedge" is formed between how the market transforms risk into wealth (as described by the slope of the hedonic wage gradient) and a worker's marginal value of safety (as described by the slope of the indifference curve). This leads to IWO posyibilities. Figure 3.1.1 shows the first case. In this situation 0 and 0 are two different for the same worker where O2 is greater than 0 levels of expected utility. Further, the hedonic wage gradient is described by WITH(T). If the labor market is operating freely, this worker will maximize expected utility by choosing a level of job related risk equal to 71. described by the slope zf !i n this situation, the worker's MVS (as 0) is equal to the rate at which the market compensates workers for taking risk (as described by the slope of WITH(n)). Therefore, if one was to estimate WL.TH(n), calculate WLTH'(r), and interpret the former as the worker's subjective MVS, one would be correct in doing so. However, level rl, if the worker was constrained to stay in a job with risk maximum level of expected utility is 0. At a level …


Internet pure plays may have won the first round of Internet retailing, but there is every reason to believe that store-based retailers will give them a run for their money. Store-based retailers, alerted by analysts' predictions that on-line retail sales could account for as much as 10 percent of total US retail sales by 2003, are joining the rush to the Internet. As yet, these store-connected World Wide Web sites generate only trivial revenue. Many have suggested that the game has emphatically gone to pure Internet plays such as Amazon.com and eToys.com. In fact, however, store-based retailers have a number of advantages over their Internet-only competitors, which can offer personalized search tools and links to related products and services but not the ability to see, touch, and try merchandise and to walk out with it. More generally, store-based retailers can leverage their multichannel advantage to give customers what they want, how and when they want it. So if store-based retailers make their sites as innovative and adaptable as those of their pure-play Internet rivals and at the same time realize synergies with their brick-and-mortar facilities, they may yet come in first after all. Choose a winning business model Building a thriving retail site on the Internet is every bit as hard as creating an exciting store environment. Like real-world retailers, on-line ones (pure play or not) must understand customer segments and shopping "occasions. But on-line retailers also have to address the complications arising from uncertainty about the behavior of Internet customers and the evolution of competitors' sites in the future. To deal with these problems, retailing incumbents moving into the on-line world must combine the three fundamentals of on-line retailing (or "e-tailing") and apply them to the business model that best suits the company and its category. The first fundamental is content--whatever appears on the Web site itself and on hot-linked Web sites--for if chosen wisely, that content can increase both the rate at which browsers are converted into buyers and their transactions. The second fundamental is community. Through site-to-user and user-to-user forms of interactivity (such as chat rooms), Web sites can generate a core of dedicated customers who become avid marketers of the site. The third fundamental is commerce, whether it involves offering goods and services directly or marketing those of another company for a fee, thus helping to cover the fixed costs of site operations and to offset customer acquisition costs. These fundamentals can be applied to four main emerging e-tailing business models: channel supporter, category killer, auctioneer, and vertical portal (Exhibit 1). Channel supporter Some store retailers use the Internet more to support their existing channels than to generate additional sales. This approach is appropriate for categories, such as fast food, that have been slow to move on-line and for retailers, such as Tiffany, whose on-line channels may be at a competitive disadvantage to their traditional ones. American Eagle Outfitters, a retailer of apparel for teens, uses the Web to deliver product information and to share fashion updates through an on-line magazine (content), to offer user forums (community), and to sell an expanded range of products--for instance, bicycles and snowboards--and to refer customers to stores (commerce). Beyond cross-channel promotions, many brick-and-mortar companies use the Web to increase their customers' understanding of their products and services. Others harness the Web's interactivity to improve their product development and product mixes by inviting customer responses on their Web sites and feeding those responses back into buying decisions at the store. Category killer Amazon, which began life as a bookseller, is the quintessential on-line example of the category killer approach, in which the retailer dominates a particular category of merchandise. …


The Perseus OB1 association hosts one of the most populous groupings of blue and red supergiants (Sgs) in the Galaxy. We discuss whether the massive O-type and blue/red Sg stars located in the Per OB1 region are members of the same population and examine their binary and runaway status. We gathered a total of 405 high-resolution spectra for 88 suitable candidates around 4.5 deg from the center of the association, and compiled Gaia DR2 astrometry for all of them. This was used to investigate membership and identify runaway stars. By obtaining high-precision radial velocity (RV) estimates, we investigated the RV distributions of sample and identified spectroscopic binaries (SBs). Most of the investigated stars belong to a physically linked population located at d = 2.5$\pm$0.4 kpc. We identify 79 confirmed or likely members, and 5 member candidates. No important differences are detected in the distribution of parallaxes for stars in h and X Persei or the full sample. On the contrary, most O-type stars seem to be part of a differentiated population in terms of kinematical properties. In particular, the percentage of runaways among them (45%) is considerable higher than for the more evolved targets (that is below 5% in all cases). A similar tendency is also found for the percentage of clearly detected SBs, which already decreases from 15% to 10% when comparing the O star and B Sg samples, respectively, and practically vanishes in the cooler Sgs. All but 4 stars in our working sample can be considered as part of the same (interrelated) population. However, any further attempt to describe the empirical properties of this sample of massive stars in an evolutionary context must take into account that an important fraction of the O stars is - or has likely been - part of a binary/multiple system. In addition, some of the other more evolved targets may have also been affected by binary evolution.


In its 16 years of existence, occupational science has achieved noteworthy success. However, to continue to thrive, the discipline must remain responsive to the changing times and environment. This paper assesses the current health of occupational science based on the plight of other academic disciplines such as sociology and geography whose futre is presently threatened. The intellectual vitality of occupational science is strong, yet the discipline must continue to solidify its interdisciplinary commitment, increase the number of publications, and expand its research scope. Beyond this, strategic planning to keep occupational science alive and well in the future will require nurturing the symbiotic relationship between the discipline and the occupational therapy profession. To the extent that occupational therapy thrives, occupational science must be better positioned, with the resource base and links to practice it needs to flourish. Finally, viewing occupational science as a kind of living organism whose survival can be described through principles of evolutionary biology can also help with the formulation of strategic initiatives. In this paper, I use this framework to identify long-term survival strategies for occupational science. I then present an heuristic model for developing customized survival plans for occupational science programs within the US and for the discipline in general. The occupational science program at the University of Southern California is used to illustrate the implementation of the heuristic model in terms of: national and global priorities; university/institutional culture, mission and values; university colleagues, networks, and programs; and departmental research and education program.I believe occupationai science will thrive in the future if occupational scientists develop and implement customized survival plans for their educational programs that are responsive to tbe opportunities and challenges present in their respective settings.


The facts:—The plaintiff brought a lawsuit against the Swiss National Bank claiming damages resulting from its allegedly false and misleading information policy. The plaintiff had taken out a loan in euros at an Austrian bank which was to be repaid in Swiss francs. In 2011, the Swiss National Bank introduced a minimum exchange rate of the Swiss franc in relation to the euro. The Swiss National Bank abandoned that policy in 2015, having repeatedly confirmed that it would be retained. The plaintiff argued that this change in policy had occurred unexpectedly. He alleged that the information disseminated prior to that change was intentionally false and misleading, causing him to refrain from converting the loan, which had resulted in losses. While the plaintiff conceded that monetary policy was a sovereign function protected by State immunity, he argued that the claim was based on the Swiss National Bank's information policy, which could have also been undertaken by a private individual. The lower courts dismissed the lawsuit on grounds of State immunity based on the European Convention on State Immunity, 1972. The plaintiff appealed.


This paper introduces a formulation and a solution methodology for the problem of optimizing the supply chain (or logistics network) of a manufacturing firm. The problem is modeled as a linear mixed-integer program with binary variables associated with design decisions such as location, product range assignment and transportation mode selection, and continuous variables representing the flows of raw materials and finished products through the network. This natural separation of variables leads to a very efficient solution approach based on Benders decomposition. While being comparable to a simplex-based branch-and-bound approach when solving a single instance of the problem, the Benders decomposition approach offers outstanding reoptimization capabilities. Its performance can in addition be improved by the introduction of simple valid inequalities that strengthen the LP relaxation by exploiting the problem structure. The formulation and solution methodology can also be adapted to handle multiple planning periods with dynamic demand, multiple stages of production and distribution, and stochastic demand in the form of a finite set of scenarios. A supply chain is a network of suppliers, manufacturing plants and warehouses organized to manage the procurement of raw materials, their transformation into finished products, and the distribution of finished products to customers. Typically, the planning of a supply chain involves making decisions regarding: • the number, location, capacity and technology of manufacturing plants and warehouses; • the selection of suppliers; • the assignment of product ranges to manufacturing plants and warehouses; • the selection of distribution channels and transportation modes; • the flows of raw materials and finished products through the network. Designing a supply chain consists of configuring the network so as to satisfy customer demands while minimizing fixed costs for facility construction or leasing and technology acquisition, and variable costs for production, storage and transportation. Because of the complexity of the problem, it is often decomposed into several components treated separately. For instance, one may first locate plants and distribution centers


Long-Term Evolution (LTE), as a 4G packet-switched wireless network, is designed to provide up to tenfold of the 3GPP speeds, and to improve network performance, latency, capacity, mobility, and flexibility. However, this design made the resource allocation a complex task in LTE. In particular, uplink scheduling in LTE is one of the main functionality challenge to enhance the throughputs at the User Equipment (UE), and at the cell. In this paper, evaluation and comparison between the performances of four LTE uplink scheduling algorithms (Round Robin (RR), Maximum Throughput (MT), Proportional Fairness (PF), and Three-Levels Hierarchical Algorithm (3LHA)) to allocate radio resources efficiently, in terms of delay, throughput, and fairness, is introduced. MATLAB simulation is used to evaluate the network performance while varying a network realistic traffic and parameters (Transmission Time Interval (TTI), number of UEs, etc.). The performance matrix of each scheduling algorithm were obtained by assigning each of the UEs the same number of Resource Blocks (100 RBs), and three types of realistic traffic (best-effort (BE), video, and voice (VoIP)). Results show a clear trade-off between the throughput and the service delay, and between the throughput and fairness.

Manipulation of a single cell of spherical shape, approximately 5–10 μm in diameter, was performed with capillary tubing and an electrostatic field. A single cell migrates with its electrophoretic mobility into capillary tubing against the flow of electroosmosis coming out of the capillary. After trapping the cell in the capillary, it is pulled out into the other microreservoir with the application of a reverse electric voltage. When we apply a negative voltage to the microreservoir itself, the cell in it can keep floating for a relatively long period due to electrostatic repulsion. The electrophoretic mobility of a single cell is also estimated.


Managerial jobs have conventionally been understood as male and thus as not being directly suitable for women. The point of departure of this discourse is that women and men are different and that there is congruence between men and managerial jobs. On the basis of a qualitative study of women managers, I argue that there is a need for more sophisticated ways of appreciating the experiences of (many) women in relation to management. Variation, complexity and contradictions may be lost when holding onto essentialist understandings such as the male norm.


Although innovation is important for all organizations, it is particularly important for consulting firms which provide customized solutions for their clients. How to make consultants become more innovative is a key question in professional service firm management. Addressing this issue, this study identifies the critical role of line managers in managing consultants and fostering their innovation. In particular, this study investigates the relationships between line manager's implementation of human resource management (HRM), consultants' innovation and the mediating mechanism of team member exchange (TMX) in this relationship. Using data from 174 team members nested in 60 consulting teams, results from multi-level analysis provide support for the mediating model where line manager's implementation of HRM is positively associated with consultants' innovation through its impact on the development of TMX. This study contributes to better understanding of the key factors influencing consultants' innovation....


Interest rate is one of the fiscal factors that is used to regulate the monetary policy of a country. The main objective of the study is to know about the interest rate prevailing with countries and to analyze about impact of interest rate towards international currency pairs. For this purpose the currencies of five countries were taken and they were compared with the interest rate to know about the impact. The conclusion that the interest rate changes has an impact towards the market in mid and long term basis with all the currencies taken for the study.


Tafelmusik Baroque Orchestra and Chamber Choir present an intimate and stirring performance of the baroque masterpiece Handel's Messiah. This 2-CD recording of the full score on period instruments features a stellar cast of soloists. Tafelmusik presents this baroque masterpiece with the spirit and vitality of Handel's own 18-century productions. "Superhuman", "spot-on", "crisp" and "inspired" are just a few of the words critics have used to describe Tafelmusik's Messiah. A perennial favourite with audiences and critics alike, Tafelmusik's Messiah has garnered glowing reviews year after year. "I cannot remember a Messiah presentation as uniformly 'spot-on' as this year's by Ivars Taurins' Tafelmusik Chamber Choir and Baroque Orchestra." (The Globe and Mail).


Firms need resilience to help them get rid of failures or crises when facing emergency, yet—surprisingly—the issue of how to activate and develop organizational resilience has not been effectively addressed. Underpinned by configuration thinking, this study uses the fsQCA method to reveal the coordination and causal complexity between the six conditions that promote or inhibit the formation of organizational resilience. Specifically, the cognitive level includes manager self-efficacy and mindful organizing; the behavioral level includes exploratory innovation and exploitative innovation; the contextual reinforcement level includes bonding social capital and bridging social capital. Using survey data from 155 firms in China, the study found that: (1) Single antecedent condition is difficult to form high organizational resilience, but the lack of bonding social capital is a necessary condition for generating non-high organizational resilience. (2) Among the different configurations of six conditions, there are four pathways to form high organizational resilience, which can be specifically classified into three modes: Exploration, Ambidextrous, and Defensive configuration. (3) Three formation pathways for non-high organizational resilience, and there is an asymmetric causal relationship with high organizational resilience. The findings enrich the theory of crisis management and organizational resilience and provide a valuable reference for enterprises to effectively stimulate organizational resilience to respond to emergencies.


Two years ago exactly, Belgium was struck by the worst terrorist attack in its history. The cell behind these deadly attacks was mostly composed of foreign fighters returning from Syria – the so-called "returnees". Since 2016, few fighters have returned, but the threat remains. This commentary looks into the evolution of the Belgian response to this phenomenon and evaluates the challenges ahead.


Objective To investigate the ring suture and tie combing with pingyangmycin injection in the treatment of hemangioma,in order to assess the value of it. Methods Ninety-three patients who suffered from cavernous or mixture hemangioma were divided into three groups: There were thirty-one patients who treated by ring suture and tie combing with pingyangmycin injection were selected as combing treatment group; Thirty-one patients were treated by pingyangmycin injection only were selected as pingyangmycin injection group; And the other patients in the ring suture and tie group were treated by suture and tie only. The ratio of cure and course were used to assess the value of these methods. Results The course was shorter (P0.05)in the combing treatment group than in the pingyangmycin injection group. The ratio of cure was higher in the combing treatment group than in the pingyangmycin injection group(P0.05) and the suture and tie group(P0.01). Conclusion The effect of suture and tie or pingyangmycin injection only was not pleasing. But combing of these two methods could short the course and improve the ratio of cure.


Abstract Selective determination of chlorinated hydrocarbons and alkylated benzenes in leachate of sanitary landfills and hazardous waste landfills was performed by headspace analysis. Identification was achieved by headspace GC MS analyses, quantitation by headspace GC, after spiking of the samples with all compounds in two concentrations (0.2 μg/250 μg). Within the hazardous waste landfills, the concentrations of chlorinated hydrocarbons ranged from 10 to 20000ppb, with methylene chloride, trichloroethylene and tetrachloroethylene as main constituents. They were detected only singularly up to 14ppb in the sanitary landfill samples. Benzene and alkylated benzenes were found in concentrations of 10 to 13000ppb in the leachates of the hazardous waste landfills and determined up to 500 ppb within the sanitary landfill leachates. The total contents of the chlorinated headspace compounds are discussed in terms of total organic chlorine with respect to the landfill type and to the corresponding AOX-values.


Development of carotage (retrospective years 1969-2019) at Taras Shevchenko National University of Kyiv is described. Basic achievements are shown in educational and scientific directions. Carbonate rocks methodology study problems, petrophysical models which allowed building physically well-founded dependences of "core-core", "core-geophysics", "geophysics- geophysics" type are described. Petrophysical simulation, theory of probability and mathematical statistics methods allowed the author to work out a complex system of data processing and interpretation in welllogging. Current status and tendency in dataware drilling process of the deep oil and gas wells are examined. Absolutely new ideology of operative getting of the reliable directional survey data without special logging services (telesystem in the process of drilling, autonomous inclinometer and other) is proposed.


In this paper, we propose a new class of quasi-cyclic low-density parity-check (QC-LDPC) codes, namely cyclically-coupled QC-LDPC (CC-QC-LDPC) codes, and their RAM-based decoder architecture. CC-QC-LDPC codes have a simple structure and are constructed by cyclically-coupling a number of QC-LDPC subcodes. They can achieve throughput and error performance as excellent as LDPC convolutional codes, but with much lower hardware requirements. They are therefore promising candidates for future generations of communication systems such as long-haul optical communication systems. In particular, a rate-5/6 CC-QC-LDPC decoder has been implemented onto a field-programmable gate array (FPGA) and it achieves a throughput of 3.0 Gb/s at 100 MHz clock rate with 10-iteration decoding. No error floor is observed up to an Eb/N0 of 3.50 dB, where all 1.14×1016 transmitted bits have been decoded correctly.


The sulphur-bridged ion, Mo2S2O22+, which has been separated from the parent compound, Na2Mo2O2S2-(cysteine)2, is stable towards acids and does not dissociate to a paramagnetic monomeric species, as does its oxo-bridged analogue, Mo2O42+, even in very concentrated acidic solutions.


In wireless sensor networks, when sensor nodes are operated with different ratios of active slots, this is called asymmetric duty cycles. Furthermore, cycles with the same ratio of active slots per cycle for all nodes are called symmetric duty cycles. In wireless sensor networks, most applications require both symmetric and asymmetric duty cycles. The balanced incomplete block design–based wake-up schedule is known to be the optimal solution for symmetric duty cycles. However, because this schedule cannot support asymmetric duty cycles, the balanced incomplete block design–based wake-up schedule is not suitable for wireless sensor networks. Herein, we propose a new scheme called the block combination–based asynchronous wake-up schedule to resolve this issue for asymmetric duty cycles. Block combination–based asynchronous wake-up schedule combines different blocks using a block combination operation. The combined schedule guarantees common active slots between sensor nodes in asymmetric duty cycles. To demonstrate the superior performance of block combination–based asynchronous wake-up schedule, we implement a TOSSIM-based simulation and compare the experimental results with recent neighbor discovery protocols such as balanced incomplete block design, prime-based block design, Disco, U-Connect, SearchLight, Hedis, and Todis. We then prove that block combination–based asynchronous wake-up schedule outperforms the others.


Tiebout's "voting with the feet" proposition directs attention to the role of local authorities in delivering public services, and the implications of their decisions in people's choice of place of residence. Similarly, the bottom-up approach to economic development places a relevant role of local governments in promoting higher standards of living. By considering the latter, the former can be extended as citizens can choose a jurisdiction not only on the basis of a combination of taxes and public services but a broader mix of public goods. This paper analyses the effects of the fundamental features of the bottom-up or local economic development (LED) approach on population mobility among Mexican municipalities. This study finds significant evidence of a positive impact of LED elements on immigration during the period between 1990 and 2005.


Abstract Unsteady magnetohydrodynamic natural convection flow with Newtonian heating and constant mass diffusion over an infinite vertical plate that applies an arbitrary time-dependent shear stress to a viscous optically thick fluid is studied in the presence of a heat source. Radiative effects are taken into consideration and exact solutions for the dimensionless velocity and temperature are established under Boussinesq approximation. The solutions that have been obtained, uncommon in the literature, satisfy all imposed initial and boundary conditions and can generate exact solutions for any motion problem with technical relevance of this type. For illustration, a special case is considered and the influence of pertinent parameters on the fluid motion is graphically underlined.


We present an unbiased method for Bayesian posterior means based on kinetic Langevin dynamics that combines advanced splitting methods with enhanced gradient approximations. Our approach avoids Metropolis correction by coupling Markov chains at different discretization levels in a multilevel Monte Carlo approach. Theoretical analysis demonstrates that our proposed estimator is unbiased, attains finite variance, and satisfies a central limit theorem. It can achieve accuracy $\epsilon>0$ for estimating expectations of Lipschitz functions in $d$ dimensions with $\mathcal{O}(d^{1/4}\epsilon^{-2})$ expected gradient evaluations, without assuming warm start. We exhibit similar bounds using both approximate and stochastic gradients, and our method's computational cost is shown to scale logarithmically with the size of the dataset. The proposed method is tested using a multinomial regression problem on the MNIST dataset and a Poisson regression model for soccer scores. Experiments indicate that the number of gradient evaluations per effective sample is independent of dimension, even when using inexact gradients. For product distributions, we give dimension-independent variance bounds. Our results demonstrate that the unbiased algorithm we present can be much more efficient than the ``gold-standard"randomized Hamiltonian Monte Carlo.


Prostate-specific membrane antigen (PSMA) is a type II transmembrane protein, which is anchored in the cell membrane of prostate epithelial cells. It is highly expressed on prostate epithelial cells and strongly up-regulated in prostate cancer. Although, 177Lu-PSMA has been recently introduced for radionuclide therapy of metastatic castration-resistant prostate cancer (mCRPC) with continuously increasing interest and use worldwide. This guideline is intended to assist nuclear medicine physicians in evaluating and managing patients with mRCPC for whom radioligand therapy (RLT) using 177Lu-PSMA is a promising treatment option. In addition, more information could be provided by subsequent investigative studies in the field of RLT.

The Integrated Meteorological System (IMETS) is a mobile, operational, automated weather data receiving, processing, and disseminating system utilized by Air Force weather forecasters in support of Army operations. The U.S. Army Research Laboratory (ARL) is supporting the forecaster to make more specific and precise battlefield weather forecasts by producing weather products on IMETS (Passner, 1993). On the IMETS, the Pennsylvania State University/ NCAR Mesoscale Model Version 5 (MM5) output is available from 6 to 48 hours and is received from the Air Force Weather Agency (AFWA.) The MM5 is a limited-area, non-hydrostatic, terrain-following, sigma-coordinate model designed to simulate or predict mesoscale and regional-scale atmospheric circulation (Dudhia, 1993).


Private Labels are steadily but slowly included in Chileans consumption baskets. However, they have not reached the market share and penetration levels of European countries. The main objective of this article is to study how customers` psychographics affect private labels buying intentions. A shopping center intercept study was conducted, interviewing 300 female shoppers, regarding 14 psychographic variables and private labels purchase intentions. Nine product categories were used, in order to improve the generalizability of findings. Using discriminant analysis, the relative importance of each psychographic variable to explain private labels purchasing intentions was assessed, in order to help retailers and manufacturers optimize their marketing efforts of private labels.

It means that contextual teaching technique was effective for teaching vocabulary at the seventh grade of SMP Gunung Jati Kembaran.


Electrochemical stimulation was performed at various stages of the estrous cycle and the release of LH estimated by the increase in plasma LH which occurred as a result of the stimulation. Plasma LH was determined by radioimmunoassay. Electrochemical stimulation of either the medial preoptic area (MPOA) or median eminence-arcuate region (ME-ARC) at 11 AM on proestrus produced dramatic elevations of plasma LH. On the other hand, similar stimulations carried out after the preovulatory surge of gonadotropins at 2300 hr were ineffective. If the preovulatory discharge of gonadotropins was blocked by treatment of the animals with Nembutal, the responsiveness to stimulation was partially restored. Stimulations of the MPOA or MEARC on diestrus day 1 produced only a slight elevation in plasma LH, whereas on diestrus day 2, there was a slightly greater response which was still much less than that obtained on the morning of proestrus. The cyclic variations in responsiveness to hypothalamic stimulation may reflect no...


The role of Omani diplomacy is visible in promoting its foreign policy and fulfilling the Sultan's vision. Since 1970, Oman adopted a different foreign policy in both regional and international arenas characterized by independence, pragmatism, and moderation. This approach was reshaped after Sultan Qaboos bin Said seized rule. His first order of business was to accelerate the steps towards modernizing the Sultanate by adopting a nation-wide social, educational, and cultural reform often referred to as the Omani Renaissance. To translate the Sultan's vision to reality, the Ministry of Foreign Affairs (MOFA) has adopted a well-structured mechanism that will enhance diplomatic relations with various countries of the world. This research highlights Oman's diplomacy strategy post-1970. It focuses on Oman's foreign policy doctrine and examines the different categories of diplomacy that have been practiced in achieving Oman's foreign policy. The research includes the following types of diplomacy: official, mediation, tolerance and co-existence, economy, cultural, water, poet, aviation, and non-governmental diplomacy. This paper attempts to contribute to academia by providing a comprehensive outlook on Oman's diplomacy, focusing on this topic from a practical point of view. It presents Omani diplomacy through dialogue and negotiations. It assembles a clear direction for the reader based on information, including personal communication with Omani diplomats.

In prior studies, academic procrastination has been discussed as an influencing factor of academic misconduct. However, empirical studies were conducted solely cross-sectionally and investigated only a few forms of academic misconduct. This large scale web-based study examined the responses of between 1359 and 2207 participants from different academic disciplines at four German universities to address the effect of academic procrastination on seven different forms of academic misconduct (using fraudulent excuses, plagiarism, copying from someone else in exams, using forbidden means in exams, carrying forbidden means into exams, copying parts of homework from others, and fabrication or falsification of data) and its variety. In measuring academic procrastination six months prior to academic misconduct, we found that academic procrastination affected the frequency of all forms of academic misconduct and its variety. We found the strongest effect of academic procrastination on using fraudulent excuses. Implications for university counseling and theory are discussed.

OF THE THESIS Hand-gesture Sensing Leveraging Radio and Vibration Signals by Song Yang Thesis Director: Yingying Chen Gesture recognition that enriches human-computer interaction (HCI) has gained considerable attention recently. Existing solutions such as computer-vision-based approaches recognize and track human hand/body gestures using cameras or visible light. However, they all require line-of-sight and are susceptible to interference from light sources. In this thesis, an innovative approach using ambient radio and vibration signals is implemented to achieve fine-grained hand/finger gesture recognition. By sensing the influence of hand/finger gestures on the transmitted radio signals (e.g., millimeter wave signals) and physical vibrations on a solid surface (e.g., tables, glass boards, acrylic boards), the position of the hand/finger can be precisely estimated through similarity and threshold-based techniques. Particularly, we implemented two types of solutions that work separately: (1) a mmWave-based strategy, where we leverage frequencymodulated continuous-wave (FMCW) radar to track hand movements and recognize various hand gestures, and (2) a vibration-based strategy, where we capture the tiny disturbance in the surface vibrations caused by a users finger touches to distinguish between different finger inputs on the surface. Extensive experiments demonstrate that our proposed approaches can accurately track and recognize users hand gestures with high accuracy.


Policy makers are increasingly looking to evidence‐based practice as a means of ensuring accountability and validity in education and more recently in e‐learning. In this paper, the origins of evidence‐based practice are reviewed, and considered in relation to the emergence of e‐learning as an area of policy, research and practice. The close links between these three activities within e‐learning are described, and a critique is presented that raises methodo‐logical, epistemological and moral questions about this approach. This analysis identifies a number of implications for e‐learning, including the problems facing practitioner‐researchers working on project funding and the potentially distorting effect of e‐learning policy on research in this field. Possible alternative approaches are suggested, advocating a more inclusive conception of evidence‐based practice in which any single model (such as the hierarchy of evidence developed within medicine) is prevented from dominating evaluation by explicitly adopting a commitment to inclusivity and empowerment within evaluation and research.


The authors consider the Ginzburg–Landau model for superconductivity. First some well-known features of superconducting materials are reviewed and then various results concerning the model, the resultant differential equations, and their solution on bounded domains are derived. Then, finite element approximations of the solutions of the Ginzburg–Landau equations are considered and error estimates of optimal order are derived.


ABSTRACT To prepare bright stock (BS) and 30# hard asphalt simultaneously, propane solvent deasphalting (SDA) of Oman vacuum residue was optimized. Result showed the optimal process conditions were as follows: extraction tower top temperature of 64°C, settling tower top temperature of 74°C, extraction pressure of 3.35 MPa, solvent ratio of 5. Compared with SDA of Oman VR to prepare bright stock and 70# asphalt, the yields of light deasphalted oil (LDAO) and heavy deasphalted oil (HDAO) were 26.8% and 24.7%, and increased by 1.7% and 5.2% respectively; carbon residue of LDAO was less than 1.2%, conformed to the feed requirement of furfural refining to produce bright stock. The yield of DOA was 48.5%, and DOA could be directly used to produce 30# hard asphalt. The PG grade of 30# asphalt was PG 76–22 and the 30# asphalt mixture had high rut dynamic stability and water resistant stability. HDAO could be used as feedstock of catalytic cracking and light yield oil (gasoline and diesel) was 65.99%.


The key receiving waterbody of effluents discharged from printing and dyeing industries in the Liaohe River Basin was identified based upon the national statistic data of the industrial pollution census. The SPE-GC-MS technique was used to qualitatively determine organic pollutants in effluents from a local integrated wastewater treatment plant(WWTP) within the textile industrial park and also from different sampling sites along the freshwater. The results show that the Haicheng River is a key receiving waterbody for the effluents discharged from printing and dyeing industries. There are 48 organic pollutants in the effluent,which mainly include types of Nheterocycles,aliphatic amines,substituted benzenes and alchohols. The diversity of organic pollutants is also observed in each selected section of the Haicheng River,and in the site of downstream,the majority of pollutants is composed of N-heterocycles and substituted benzenes. There are 9 well-known toxic pollutants,i. e. dimethyl phthalate(DMP),dibutyl phthalate(DBP),di-n-octyl phthalate,p-xylene,aniline,p-dichlorobenzene,4-methyl nitrobenzene,dinitrotoluene and naphthaline that are in both US EPA and Chinese priority pollutant list.


Forty years ago, Manuel Castells asked whether urban sociology had a subject matter and whether the term urban still had meaning—and this article reopens these and related questions. It also wonders why today's American urban sociology has concentrated on cities, especially big ones, concurrently virtually ignoring the three other types of communities—suburbs, towns, and rural areas—in which a majority of Americans live and work. Further, it argues that this four–community typology is logically dubious and empirically obsolete. If the field were redefined as a sociology of settlements, analytically more logical and substantively more relevant typologies could be developed. Another politically and organizationally more realistic alternative would split the field into four: a sociology of the city and one concentrating on other settlements, with a third field devoted to community studies, and the fourth to spatial sociology.


Patient recruitment and drug supply planning are the biggest challenges for clinical study design. The innovative statistical technique for modeling patient recruitment in multicentre clinical trials is proposed. It allows predicting recruitment with confldence boundaries at initial and ongoing stage of the study, evaluating study/centre performance and the minimal number of centres needed to complete recruitment in time with a given confldence, providing adaptive adjustment. Predicting in time the recruitment proflle provides the opportunity to evaluate drug supply needed to cover patient demand for a given risk of patient stock out and establishes the basis for a novel approach in optimizing drug supply planning. The developed in R software tools use derived closed-form expressions, no Monte Carlo simulation involved. Technique is validated on real data, case studies are considered. The results are illustrated for several case studies.


The aerosol radiative effects (ARE) on the deep convective clouds are investigated by using a spectral-bin cloud-resolving model (CRM) coupled with a radiation scheme and an explicit land surface model. The sensitivity of cloud properties and the associated radiative forcing to aerosol single-scattering albedo (SSA) are examined. The ARE on cloud properties is pronounced for mid-visible SSA of 0.85. Relative to the case excluding the ARE, cloud fraction and optical depth decrease by about 18% and 20%, respectively. Cloud droplet and ice particle number concentrations, liquid water path (LWP), ice water path (IWP), and droplet size decrease significantly when the ARE is introduced. The ARE causes a surface cooling of about 0.35 K and significantly high heating rates in the lower troposphere (about 0.6K/day higher at 2 km), both of which lead to a more stable atmosphere and hence weaker convection. The weaker convection and the more desiccation of cloud layers explain the less cloudiness, lower cloud optical depth, LWP and IWP, smaller droplet size, and less precipitation. The daytime-mean direct forcing induced by black carbon is about 2.2 W/sq m at the top of atmosphere (TOA) and -17.4 W/sq m at the surface for SSA of 0.85. The semi-direct forcing is positive, about 10 and 11.2 W/sq m at the TOA and surface, respectively. Both the TOA and surface total radiative forcing values are strongly negative for the deep convective clouds, attributed mostly to aerosol indirect forcing. Aerosol direct and semi-direct effects are very sensitive to SSA. Because the positive semi-direct forcing compensates the negative direct forcing at the surface, the surface temperature and heat fluxes decrease less significantly with the increase of aerosol absorption (decreasing SSA). The cloud fraction, optical depth, convective strength, and precipitation decrease with the increase of absorption, resulting from a more stable and dryer atmosphere due to enhanced surface cooling and atmospheric heating.


The Amazonian tropical rainforests have historically been the target of nonsustainable land use practices, remain the scars of degradation from predatory logging, indiscriminate use of fire, high rates of deforestation and other activities that interfere in forest biodiversity conservation actions. In this scenario, the State actuation through policies that encourage more sustainable uses is needed, like the forest concession that seeks to contribute to natural resources conservation and maintenance of biodiversity through forest management. The generation of products like Normalized Difference Vegetation Index, Linear Spectral Mixture Model and Canopy Gap Fraction was done in order to create elements of interpretation and analysis of the canopy openness variable. This research studied the Forest Management Unit I of the Mamuru-Arapiuns lot, west region of Para state, where canopy openness of this forest concession area was quantified and evaluated through multispectral images and hemispherical photographs to analyze the degradation and quality of the management executed in this area. The results obtained showed that is possible to establish a monitoring process by the use of the sensors and technics applied, once the LSMM data, specially the unmixed image soil showed strong covariance relation with the field data from hemispherical photographs, allowing it to be considered a good warning tool to amazon forests monitoring actions. This way, it is possible to make the management of forests more accessible to the government and non-governmental or private organizations to police the logging actions and aggregate the population that live on these areas, with income opportunities and forest conservation.

In order to solve the problem of low efficiency of single-state on-line detection of high voltage switchgear in the past, an on-line monitoring system based on Modbus mode is designed for the monitoring of the comprehensive state including insulation, mechanism and thermal. The system is composed of coil current sensors, temperature sensors, TEV sensors, ultrasonic sensors, data acquisition system, slave computer and host computer. The Modbus mode adopts a one-master and multi-slave control mode, which allows the realtime control of the host computer on multiple sensors of the multi-face high voltage switchgears. In addition, three system control strategies are designed to ensure the high efficiency and reliability of the monitoring system. Finally, the system is proved to be effective by field testing.


Expert site assessment, based on field geochemical investigation, is the only possible method how to discover or how to monitor contaminated land and water pollution. In spite of this irreplaceable basic role for problem identification and evaluation, there is often more attention given to the successive (computational) elaboration of data or to the presentation of the final conclusions. The acquisition of relevant and reliable input information represents a complicated task which importance has to be highlighted as a vital part of the assessment. The Czech experience and expertise in this sphere is currently being driven by an ongoing process of wide privatization, which is connected with the necessity to solve problems caused by former environmental damages or at least to identify the problems, to evaluate their urgency and to propose solutions.


Energy Education Partnership, Inc. (EEPI) is a 501(c) (3) subsidiary of the Interstate Oil and Gas Compact Commission (IOGCC). The organization was formed four years ago for charitable, educational, and scientific purposes. EEPI adheres to the same mission of IOGCC, and that is to promote conservation and efficient recovery of domestic oil and natural gas resources while protecting health, safety and the environment. The membership of EEPI/IOCGG is composed of the governors of the 30 oil and gas producing states, seven associate member states, and five international affiliates. The governors appoint official representatives and committee members to participate in the programs. The membership of EEPI/IOGCC is dedicated to the conservation and prudent utilization of oil and natural gas resources through education and training. Engineers, geologist, environmental scientists and researchers who perform the majority of fossil energy research in the United States all work with EEPI/IOGCC on projects. The ''Oil and Gas Facility Emergency Awareness Program'' consists of three main parts, with two optional projects for the states involved in the pilot program. The three main parts of the program consist of the following: (1) Create a generic publication using the Ohio Oil and Gas Energy Education Program's publication, ''Responding to Oilfield Emergencies'', which is not state-specific. (2) Prepare a training program for emergency response teams, state and federal regulators, oil and gas facility owners and operators, and local citizens. The program will be developed as a PowerPoint presentation and will assist the students in becoming more aware of emergency situations at an oil or gas facility. The students learn who is the designated ''first responder'' in charge, how all people can work together in preventing and controlling problems at an oil or gas facility, and what to do during an emergency. Familiarity with equipment and hazardous substances are introduced as part of the program. (3) Once the publication and the training program are developed, a video that will be used as an introduction to the actual training class, as a refresher for the class, or in a ''train-the-trainer'' program will be produced. In addition to the above-noted three steps, optional projects were considered by the pilot program states. Two optional projects were considered by the states: (1) Working with the local, regional or state firefighters, a training facility would be created using oil and gas equipment. This part of the project will require cooperation between firefighters and industry, and will assist especially the emergency responders in learning more about oil and gas equipment. (2) Also under consideration was a related web site that would include the location of all oil and gas wells and accessible only by password. The overall ''Oil and Gas Facility Emergency Awareness Program'' has many benefits, some of which are: The process will provide opportunity for key industry leaders to develop relationships with local emergency management agencies. Industry personnel will be able to better understand emergency planning, and emergency personnel will better understand industry operations. Health, safety and environment will be better protected because of training. Better risk management will improve the operating climate for independent oil and gas producers. The ''Oil and Gas Facility Emergency Awareness Program'' benefits the emergency response teams, oil and gas facility owners and operators, state and federal regulators, the environment, and most especially the citizens. All groups must work together for the health, safety and protection of the community and the environment.


High pressure saltwater zones and gypsum zones were frequently encountered in wells drilled in the Jidike Formation in Kuche Sag in the south of Tianshan area. Salt and calcium contamination and difficulties in maintaining good mud rheology as well as downhole troubles such as pipe sticking and mud losses made drilling operation quite difficult. To address these problems, a potassium polymer mud was chosen, combined with pertinent mud property control technology such as density and rheology control, precise bentonite content and chloride concentration management, and engineering measures. Field practice showed that the potassium polymer mud (treated with some sulfonates) had stable rheology and good tolerance to drilled solids contamination. Gauged holes were obtained using this mud and the said technologies. All wells drilled with this mud were 100% successful in RIH to bottom. Furthermore, emulsified olefin and ultra low filtration rate filming drilling fluid technology was used in the reservoir section to protect the permeability of this section and good oil shows were obtained.


From 1980 to 2012 there were 80% carbon dioxide emission from traditional fossil energy in the world, and the proportion reached 90% in China, which was the top of carbon dioxide emission and energy consumption. In order to release the pressure of short term energy-saving and emission-reduction, as well as implement energy system cleaning in long term, reversing the positive situation of energy structure adjustment and the advancing the continuous evolution of energy consumption structure will be the effective methods. This paper takes Hebei Province and the whole country as the research objects, analyzes the influence of energy consumption structure changes on carbon dioxide emission and the correlation effect between energy consumption structure and carbon dioxide emission intensity by constructing a correlation model between energy consumption structure and carbon dioxide emission intensity, discusses the effective strategies for the regional energy-saving and emission-reduction.


For raising the quality of operation of the vibrat ory technologic machines a precision of the treatme n and assemblage of their constructions separate details and units has a particular importance. Specificity of elastic elements (especially of springs) – to oscillate not only in direction of the acting force but also in spatial ( non-working) directions, is of no small importance. An attempt is made in the presented work to elabora te a common generalized dynamical model of the vibr atory technologic machine, moving in the space due to abo ve mentioned reasons. The following possible deviations are envisaged in the model: of treatment and assemblage of the machi ne; of interlocation of elastic elements with supporting s urfaces; of transfer of the exciting force. Dynamical and mathematical models of spatial moveme nt of the loaded vibratory technologic machine, con sidering above mentioned possible deviations, are elaborated. Numerical experiments of generation of non-working spatial vibrations and their influence on behaviour f the friable technologic load, are carried out. A part of the re search results is presented in this work.


Abstract : The problem of computing stresses accurately and reliably in the case of nearly incompressible solids and in the incompressible limit of the compressible Navier-Stokes equations has received a great deal of attention in recent years. Formulations based on the principle of virtual work have been abandoned in favor of mixed and penalty methods in order to avoid locking which occurs when elements of low polynomial degree are used. An overview of the evolution of mixed and penalty methods and a clear exposition of the locking phenomenon is available. A mixed formulation which has been successfully applied to elastic and inelastic problems is presented. Mixed formulations have been used successfully in fluid dynamics in conjunction with elements of high polynomial degree.

Abstract The long‐term results of 292 consecutive eyes with a perforating eye injury without an intraocular foreign body treated with or without pars plana vitrectomy are reported. With the mean follow‐up time of 31.0 months 45 eyes (15%) were enucleated and another 47 eyes (16%) were blind (visual acuity <0.05). The retina was attached in 87% of the non‐enucleated eyes. The visual outcome was considerably better in eyes with anterior segment injuries (ASI) compared to posterior segment injuries (PSI). Eyes with primary vitreous haemorrhage had poorer visual prognosis than eyes without haemorrhage. Vitrectomy improved the prognosis of the former eyes, but in the whole series the visual acuity was better in eyes in which vitrectomy was not performed (not considered indicated). Of the vitrectomized eyes, 55% in the ASI group and 25% in the PSI group received useful vision (visual acuity ≥ 0.05). Excluding the very late vitrectomies, a statistically significant correlation was found between the timing of vitrectomy and the late visual outcome.


Free-electron lasers (FELs), which use the kinetic energy of an electron beam to generate or to amplify a beam of coherent light, can be configured as either oscillators or amplifiers. In the oscillator design, the wiggler field is inside a resonant cavity. When the beam passes through the wiggler and cavity, the radiation, which builds up from noise inherent in the system, is confined within the cavity to interact with and modulate the electron beam. The rest is allowed to escape to become the usable laser beam. In the amplifier configuration, an electron beam passing through a wiggler (a series of magnetic fields of alternating polarities) is simultaneously exposed to laser light of the desired wavelength. Under the influence of the laser light, the electrons tend to lock in and emit light in the same phase. The coherent signal grows in intensity as it passes through the amplifier. For a given wiggler geometry (with the segments of the magnetic field as close together as practical) the frequency of the emitted light is inversely proportional to the square of the energy of the electron beam. Our Experimental Test Accelerator (ETA), with its 4.5-MeV electron beam, is suitable for FEL experiments in the millimetre (microwave) regime, whereas the operating regime for FEL experiments on our Advanced Test Accelerator (ATA), with its 50-MeV electron beam, is at micrometre (infrared) wavelengths. Although experiments with both beams are based on the same design principles, there are fundamental differences in the two sets of experiments. The wavelength in the ETA experiments is 8.4 mm, relatively long with respect to the diameter of the electron beam (the region where the interaction with the radiation's field takes place). This means that we must confine the microwave radiation and channel it through a conducting tube (a waveguide) to keep it from dissipating by diffraction. In the ATA experiments, by contrast, the operating wavelength (10.6 11m) is much smaller than the beam diameter so the radiation propagates like light through a refractive laser medium. The two experiments also use different techniques to control horizontal spreading of the electron beam in the wiggler field, but in both cases the fields of the wiggler magnets focus the beam in the vertical direction. In our Electron Laser Facility (ELF), in which we perform experiments with the ETA, there is an external set of quadrupoles for horizontal focusing (see Fig. 1 for a schematic layout of the ELF). In our Paladin experimental facility, associated with the AT A, the


The precise classification for the electroencephalogram (EEG) in different mental tasks in the research on brain–computer interface (BCI) is the key for the design and clinical application of the system. In this paper, a new combination classification algorithm is presented and tested using the EEG data of right and left motor imagery experiments. First, to eliminate the low frequency noise in the original EEGs, the signals were decomposed by empirical mode decomposition (EMD) and then the optimal kernel parameters for support vector machine (SVM) were determined, the energy features of the first three intrinsic mode functions (IMFs) of every signal were extracted and used as input vectors of the employed SVM. The output of the SVM will be classification result for different mental task EEG signals. The study shows that mean identification rate of the proposed algorithm is 95%, which is much better than the present traditional algorithms.


Image registration is generally an indispensable part of super-resolution reconstruction. The accuracy of registration results directly affects the quality of super-resolution reconstruction which utilizes the information of aliased images in sub-pixel displacement. In this paper, we propose a hybrid frequency-spatial domain registration approach to address this problem. It effectively combines both the advantages of frequency and spatial domain algorithms and is implemented in three phases in a coarse-to-fine fashion. Our algorithm is then compared with a conventional frequency domain approach. The simulation results show that the proposed algorithm is more precise and robust than the conventional one.


Proton Magnetic Relaxation Dispersion (PMRD) measurements were carried out over a wide Larmor frequency range near the isotropic-nematic transition temperature (T NI) and in the mid nematic phase of a low viscous liquid crystal 4-(trans-4′-hexylcyclohexyl)-isothiocyanatobenzene (6CHBT), with a view to examining the pre-transitional effects just above isotropic-nematic transition (T > T NI) and the role of director fluctuations (DF) on the nematic phase stability of this system. The results near the transition indicate critical slowing down of the short-range nematic order modes just above T NI with a mean field critical exponent characterizing the coherence length (ξ). The observed temperature independence of the correlation time associated with the reorientations (τR) and the extension of DF mode spectrum, in the mid-nematic phase, to relatively higher resonance frequencies seem to suggest fairly low hindering barriers for the tumbling of the molecules about their short axes.


ABSTRACT The health emergency generated by COVID-19 and the massive closure of schools has given rise to an unprecedented situation for education systems worldwide. This situation has raised fundamental questions about the role of the school in contemporary societies and whether it still fulfils a particular function as a social institution. This article forwards a theoretical discussion on these issues from a critical sociological approach and, especially, from the perspective of social justice. It argues that the two main functions of schools, namely, socialisation and selection, cannot be fully achieved by distance schooling. Moreover, it contends that the lockdown of schools reinforced the crisis of meaning within the school system by hindering its ability to ensure learning for all students. Overall, the article presents a reflection on the meaning of the school institution in the 21st century, representing a key contribution to contemporary debates on the sociology of education.

Companies are generally established with the aim of making a profit. The company's operational activities cannot be separated from the use of external funds to support the company's activities. This study examines the effect of leverage on financial performance. In addition, this study also examines the ability of firm size as a moderating variable. This research is expected to contribute to management to consider the size of the company owned so that it is effective in improving company performance. The number of samples analyzed was 54 samples in the form of financial reports from banking sector companies listed on the Indonesia Stock Exchange. The sampling technique in this study is the non-probability sampling method with a purposive sampling technique with the criteria of companies (issuers) that have issued financial reports consecutively for the 2019-2021 period and companies (issuers) that have not suffered losses during the 2019-2021 period. The analysis technique used is simple linear regression and Moderated Regression Analysis (MRA). The results of the analysis show that leverage has no effect on company performance. Firm size weakens the effect of leverage on firm performance.


Two situations indicate the need of bringing closer music education and the educational community. Elementary school teachers struggle to mediate a relation between their students and knowledge about music. In addition, a contradiction between Brazilian elementary schools and educational programs for primary school teacher exists, in relation to knowledge about music. In an attempt to bridge this gap, the present article aims to review the main ideas on educational programs for primary school teacher from the leading specialists on music education in Brazil.


This study attempted to identify the impact of internal work environment on the retention of healthcare providers at Turaif General Hospital in the Kingdom of Saudi Arabia. In particular, the study aimed to identify the dimensions of work circumstances, compensation, and relationship with colleagues, professional growth, and the level of healthcare providers' retention. In order to achieve the study goals, the researcher used the descriptive analytical approach. The researcher used the questionnaire as the study tool. The study population comprised all the healthcare providers at Turaif General Hospital. Questionnaires were distributed to the entire study sample that consisted of 220 individuals. The number of questionnaires valid for study was 183 questionnaires. The research findings were as follows: the participants' estimate of the work circumstances dimension was high (3.64), the participants' estimate of the compensation dimension was moderate (3.32), the participants' estimate of the relationship with colleagues dimension was high (3.62), the participants' estimate of the professional growth dimension was weak (2.39), and the participants' estimate of healthcare providers' retention level was intermediate (2.75). Accordingly, the researcher's major recommendations are: the need to create the right atmosphere for personnel in hospitals, the interest of the hospital to provide the appropriate conditions for the staff in terms of the physical and moral aspects for building the work adjustment in the staff, and conducting training courses and educational lectures for personnel in hospitals on how to cope with the work pressures.

Chapter 7.6 of ASCE 4-Rev 2, Seismic Analysis of Safety-Related Nuclear Structures: Standard and Commentary, provides updated guidance for analysis of rocking and sliding of unanchored structures and components subjected to seismic load. This guidance includes provisions both for simplified approximate energy-based approaches, and for detailed probabilistic time history analysis using nonlinear methods. Factors to be applied to the analytical results are also provided with the intent of ensuring achievement of the 80% non-exceedence probability target of the standard. The present paper surveys the published literature supporting these provisions. The results of available testing and analysis are compared to results produced by both simplified and probabilistic approaches. In addition, adequacy of the standard's provisions for analysis methods and factors is assessed. A comparison is made between the achieved level of conservatism and the standard's non-exceedence probability target.


The natural ecosystem incorporates thousands of plant species and distinguishing them is normally manual, complicated, and time-consuming. Since the task requires a large amount of expertise, identifying forest plant species relies on the work of a team of botanical experts. The emergence of Machine Learning, especially Deep Learning, has opened up a new approach to plant classification. However, the application of plant classification based on deep learning models remains limited. This paper proposed a model, named PlantKViT, combining Vision Transformer architecture and the KNN algorithm to identify forest plants. The proposed model provides high efficiency and convenience for adding new plant species. The study was experimented with using Resnet-152, ConvNeXt networks, and the PlantKViT model to classify forest plants. The training and evaluation were implemented on the dataset of DanangForestPlant, containing 10,527 images and 489 species of forest plants. The accuracy of the proposed PlantKViT model reached 93%, significantly improved compared to the ConvNeXt model at 89% and the Resnet-152 model at only 76%. The authors also successfully developed a website and 2 applications called 'plant id' and 'Danangplant' on the iOS and Android platforms respectively. The PlantKViT model shows the potential in forest plant identification not only in the conducted dataset but also worldwide. Future work should gear toward extending the dataset and enhance the accuracy and performance of forest plant identification.
