A systematic investigation has been conducted to demonstrate applicability of reverse osmosis (RO) fractionation of organic liquid mixtures by laboratory-prepared cellulose acetate butyrate (CAB) and aromatic polyamid (PA) membranes. The determination of preferential sorption was also conducted by using liquid chromatography technique. It was found that reverse osmosis was applicable to the fractionation of organic liquid mixtures. It was also found that the component of the binary mixture that is enriched in the membrane permeate can be predicted by considering the preferential sorption and Stokes' radius for each constituent of the feed mixtre.

A three-yrea program research in laser physics and techniques has been carried out to help meet Air Force mid- and long-term requirements. Development of an optically pumped atomic mercury laser was completed. Picosecond spectroscopy experiment led to measurements of ultrafast relaxation and diffusion times in solids. Work on efficient numerical methods for optical resonator calculations resulted in a Fast Hankel Transform for calculations in cylindrical coordinates. Improvements to the FHT algorithm have been made and a two-stage algorithm developed. An efficient procedure for analyzing nonlinear beam interactions has been developed; also several fundamental questions on aspects of laser resonators have been resolved. A diffraction-biased ring resonator was invented, and an analysis of phase conjugate mirror resonators carried out. Studies of optically pumped lasers including mercury dimer as a potential laser mechanism were carried out. A number of two photon laser systems were investigated, and studies of four-wave mixing as a frequency conversion process completed. Improvements in the growth of lithium niobate crystals led to higher power tunable infrared and visible sources. Finally, stimulated rotational Raman scattering was demonstrated for efficient frequency conversion in the infrared.

The development of accurate forecasting systems for real-world time series modeling is a challenging task. Due to the presence of temporal patterns that change over time, the adoption of a single model can lead to underperformed forecasts. In this scenario, Multiple Predictor Systems (MPS) emerge as an alternative to adopting single models since they struggle to learn in the presence of temporal patterns that change over time. Dynamic prediction/ensemble selection is a special case of MPS where each model is an expert in the time series's specific patterns. In dynamic selection, instead of combining all models, the most competent models per test pattern are selected. A criterion commonly used is to evaluate the models' performance in the region of competence, formed by the patterns present in the in-sample set (training or validation sets) more similar to the test pattern. Thus, the region of competence's quality is a key factor in the precision of the MPS. However, adequately defining the similarity criterion and the size of the region of competence is challenging and problem-dependent. Furthermore, there is no guarantee that similar data exist in the in-sample set. This paper proposes a dynamic selection approach entitled Dynamic Selection based on the Nearest Windows (DSNAW) that selects one or more competent models according to their performance in the region of competence composed of the nearest antecedent windows to the new target time window. This strategy assumes that the temporal windows closer to a test pattern have a behavior more similar to the target than in-sample data. The experimental study using ten well-known time series showed that the DSNAW outperforms the literature approaches.


Abstract A common goal of all dyers is to achieve the correct shade as early as the first dyeing. But the disperse dyeing process is very complex, being characterized by the diffusion-controlled sorption of dyes that depends on several physicochemical parameters such as dye concentration and temperature of application. Wilson and Hill developed equations describing the uptake of disperse dyes by cylindrical fibres as a function of the diffusion coefficient and the nature of the dyebath. This coefficient is a physical term that permits comparison between different dyeing experiments. However, the literature reveals no equation that expresses the influence of experimental parameters on the diffusion coefficient value. Thus, this work proposes a mathematical model describing the evolution of this diffusion coefficient for disperses dyes as a function of time, initial dye concentration, and the nature of the dyebath (finite or infinite).


A thin corpus callosum on magnetic resonance imaging (MRI) characterizes a type of autosomal recessive disorder with progressive spastic paraparesis and cognitive impairment. Known as Hereditary Spastic Paraparesis with Thin Corpus Callosum (HSP‐TCC), it has been associated with mutations of the SPG11 gene. No other specific MRI findings have been reported.


Introduction: The pseudoexfoliation (PEX) syndrome is a production and deposition of fibrillar extracellular material in ocular structure. The prevalence of PEX based on hospital reports from India varies between 1.87% and 13.5%. Aim: To study the prevalence of PEX, and complications during cataract surgery due to the pupillary rigidity and zonular weakness and instability as well as post-operative complications. The purpose of this study was to assess the frequency and types of complications of small incision cataract surgery (SICS) in patients with cataract and PEX. Materials and Methods: A cross-sectional descriptive study was conducted on 3334 eyes of 512 patients with cataract and PEX who underwent SICS in a tertiary care hospital from 1st July 2013 to 31st December 2016. The PEX was diagnosed by the presence of gray flakes on the anterior lens capsule or at the pupillary margin or both. Results: Prevalence of PEX was 15.53% (512 cases). 358 (69.92%) patients were male, and 154 (30.07%) cases were female. There was tendency of increasing prevalence of PEX with advancement of age, 4 (1.24%) in 41-50 years, 51 (9.96%) in 51-60 years, 162 (31.45%) in 71-80 years, 213 (41.11%) in 71-80 years, and 88 (16.98%) were >80 years of age group. Poor pupillary dilatation in spite of the use of standard mydriatic drops and nonsteroidal anti-inflammatory drugs was the most common finding in 334 (65.32%) cases. In 62 (12.10%) cases, a supplementary procedure of pupillotomy was done. Other problems encountered were accidental iridodialysis in 6 (1.17%), zonular dialysis in 7 (1.36%) posterior capsule rupture with vitreous loss in 14 (2.73%), retained cortical matter in 44 (8.59%), and decentered intraocular lens 23 (4.49%) cases. Conclusion: Presence of associated PEX in cataract patients significantly increases the risk of vision-threatening complications. Use of flexible iris hooks for small pupils and capsular stability are advocated, capsular tension rings and high viscosity viscoelastics are useful modifications of surgical technique for good visual outcome.

We have directly detected millimeter wave (mm-wave) free space superradiant emission from Rydberg states ($n \sim 30$) of barium atoms in a single shot. We trigger the cooperative effects with a weak initial pulse and detect with single-shot sensitivity and 20 ps time resolution, which allows measurement and shot-by-shot analysis of the distribution of decay rates, time delays, and time-dependent frequency shifts. Cooperative line shifts and decay rates are observed that exceed values that would correspond to the Doppler width of 250 kHz by a factor of 20 and the spontaneous emission rate of 50 Hz by a factor of $10^5$. The initial superradiant output pulse is followed by evolution of the radiation-coupled many-body system toward complex long-lasting emission modes. A comparison to a mean-field theory is presented which reproduces the quantitative time-domain results, but fails to account for either the frequency-domain observations or the long-lived features.

Although the total variation based gradient descent (TV-GD) algorithm has revealed a good performance for photoacoustic imaging (PAI), fast or real-time imaging remains a challenge. In this paper, the data dependencies that exist in the TV-GD algorithm were exploited, and a general expression was then for the first time derived to unroll the inner loop that occupied the majority of the entire running time of the algorithm. All the terms consisting of the measurement matrices or the under-sampled datasets were then extracted and preprocessed rather than being calculated along with reconstruction. For implementation, we accessed the JACKET toolbox to parallelize the execution of the matrix-vector multiplications and the vector additions generated by the general expression itself. The under-sampled dataset with 30, 60, 90 and 120 projections were adopted to reconstruct a 128×128 Shepp-Logan Phantom. The simulation results revealed a minimum reconstruction time of 0.64s in the case of the 60-view data, and a maximum speedup of 69X from the 120-view dataset.


Evidence based on ongoing published research shows that timetabling has been a challenge for over two decades. There is a growing need in higher education for a learner-centered solution focused on individual preferences. In the authors' earlier published work, students' group assessment information was mined to determine individualized achievements and predict future performance. In this paper, they extend the work to present a solution that uses students' individualized achievements, expected future performance, and historical registration records to discover students' registration timing patterns, as well as the most appropriate courses for registration. Such information is then processed to build the most suitable timetable for each student in the following semester. Faculty members' time preferences are also predicted based on historical teaching time patterns and course teaching preferences. The authors propose a modified frequent pattern (FP)-tree algorithm to process the predicted information. This results in clustering students to solve the timetable problem based on the predicted courses for registration. Then, it divides the timetable problem into subproblems for resolution. This ensures that time will not conflict within the generated timetables while satisfying both the hard and soft constraints. Both students' and faculty members timetabling preferences are met (88.8% and 85%).


Nonempirical study of the site preference occupation for Ni and V substituting in Fe3Al has been carried out in the framework of the coherent potential approximation. Obtained values of total energies show in a full agreement with experiments that Ni atoms in the equilibrium configuration occupy the iron sub-lattice for alloying with 5 at % of Ni in the Fe3Al-based alloy. Calculations of alloys with the V-doped iron aluminide in the D03 phase show differences in bonding and site occupation preferences in comparison with Ni doping. V atoms occupy aluminum sublattice.


Effects of minor addition of reactive elements (Ce, Hf, La, Y and Zr) on the structural and dynamical properties of liquid chromia were investigated by the ab-initio molecular dynamics approach. The calculation results show that minor doping of reactive elements has a significant effect on the diffusivity of chromium and oxygen ions. It is observed that Hf and La are the most efficient elements in retarding the diffusion of chromium and oxygen, Ce and Y are the secondarily efficient, while Zr is the least efficient. The relative bonding strength between doping elements and oxygen was found to be in descending order of Hf-O>Zr-O>(Ce,Y)-O>LaO, which could be estimated from the major peak intensity of pair correlation functions or the value of mean residence time. Our calculation results are in satisfactory agreement with those obtained from experimental measurement and thermodynamical database. The mechanism regarding the effects of reactive element on diffusivity was further analyzed in view of possible factors: ionic size, bonding strength, and ionic weight. It turns out no sole factor could be responsible for the relative efficiency of reactive elements, and a novel evaluation parameter combining these factors was proposed.

G protein‐coupled receptor 35 has been an orphan receptor, although synthetic agonists and antagonists have been developed. Cromolyn and lodoxamide, mast cell stabilizers, were reported as agonists. Recently, cromolyn exhibited antifibrotic effects through actions on hepatocytes and stellate cells. However, the function of GPR35 in hepatocytes has not been investigated.


An efficient and sound financial system is crucial to enhancing sustainable economic growth in any country, as it provides a balance between those who have funds to invest and those in need of these funds. The creation of credit is a source of revenue for banks just as it makes up the majority of bank's assets. This is however a very risky outcome, as there is the risk of insolvency if less return is earned from its credit portfolio. The interest gotten from risk assets contributes significantly to interest income of banks, and about 85% of banks total income, thus exposing banking business to credit risk. When banks are exposed to high credit risk, it could lead to loans becoming non-performing and putting banks at high risk. Thus, regulatory policies are established to enable banks and other financial institutions have enough protection when carrying out their functions. In lieu of these, this study is carried out to examine the effect of capital regulatory policies on non-performing loans of commercial banks in Nigeria. Data on a sample of 15 commercial banks quoted on the Nigerian Exchange Group as at 31st December 2021 were analyzed using the panel regression models. The results showed a positive and significant effect between capital regulatory policies and non-performing loans of commercial banks. The study also showed that banks in Nigeria were able to survive high rate of non-performing loans because they were able to take the policies set out by the regulatory bodies into consideration. Based on the findings, the study advised the need for commercial banks to strictly adhere to the capital regulatory policies of government to be able to operate efficiently and effectively in a harsh economy like Nigeria.


Objective To study the pattern of the distribution of NGF (nerve growth factor)and BDNF(brain - derived neurotrophic factor) in adult rat motocortex following complete spinal cord transection (SCT) .Methods With immunohistochemistly and quantitative analysis by PIPS - 2020 superhigh resolution pathology image analysis system, the expression and distribution of NGF and BDNF were investigated in motocortex following complete SCT. Results NGF and BDNF immunoreactive positive cells are mainly localized in motocortex layer V in both control and experimental groups. The expression of NGF in adult rat motocortex was up - regulated transiently after transection and reached the peak in day 7. The expression of BDNF was increased after SCT and reached the peak at day 21. Conclusion The up - regulation of NGF occurred earlier than that of BDNF in adult rat motocortex following SCT.


A 23-year-old man with normal antenatal history was admitted to hospital because of right hypochondrial pain, periodic nausea, and fatigue. The patient reported an episode of idiopathic jaundice with moderate fever 5 years previously. He was a non-smoker who did not drink alcohol nor take oral or intravenous drugs. Evaluation for viral hepatitis was negative. His physical examination revealed a high body mass index (BMI) of 32.2 kg/ m2, his liver was palpable 2 cm below the costal margin, but his spleen was nonpalpable. Laboratory test results showed a leukocytosis, as well as high levels of total bilirubin (29.2μmol/L), conjugated bilirubin (7.7 μmol/L), AST (48U/L), total cholesterol (7.58mmol/L), triglycerides (1.82mmol/L), LDL-C (5.29mmol/L), and VLDL-C (0.83mmol/L), but his HDL-C level was normal (0.67mmol/L). Abdominal ultrasonography showed hepatosplenomegaly with moderate diffuse parenchymal changes in the liver (liver steatosis) and pancreas. Arteriosclerotic vascular disease with hemodynamically relevant stenotic brachiocephalic vessels (20%–35%) was found on brachiocephalic vessel ultrasonography. Upper gastrointestinal endoscopy revealed regions of flat yellowand brown-speckled pigmented mucosa from the descending part of the duodenum to the fourth part (▶Video 1). Histopathological examination of a biopsy taken from the duodenal mucosa showed numerous macrophages containing brownish granules in their cytoplasm (▶Fig. 1). Staining of the specimen with Perls' stain for iron-containing deposits was completely negative (▶Fig. 2). An ultrasonography-guided liver biopsy was performed, the results of which revealed moderate histologic hepatitic activity, fibrous degeneration (grade 3), and severe steatosis with an accumulation of foam cells. Homozygosity for pSer103Arg+/0 IVS81G>A was found on genetic sequence analysis of the LIPA gene. Lysosomal acid lipase (LAL) deficiency cholesteryl ester storage disease (CESD) was confirmed. LAL deficiency is a rare (orphan) autosomal recessive lysosomal lipid storage disorder caused by mutations in the LAL gene (LIPA), which is characterized by the accumulation of cholesteryl esters and triglycerides [1, 2]. Depending on the residual enzyme activity, two different presentations may be seen: an earlyE-Videos

In this work, we present a methodology of simple yet accurate calculations of H2O(v 2) vibrational levels pumping from the collisions with vibrationally excited O2(X3Σ −  g , v = 1) molecules, which is required for correct retrievals of H2O volume mixing ratios from the 6.3 μm band radiance. The electronic-vibrational kinetics model of O2 and O3 photolysis products used in this study includes 44 electronic-vibrational states of the O2 molecule (three states of O2(b1Σ +  g , v), six states of O2(a1Δ g , v) and 35 states of O2(X3Σ −  g , v)) as well as the first excited state of atomic oxygen, O(1D) and considers more than 100 photochemical reactions linking these states. We introduce the Resulting Quantum Output (RQO) approach that describes the O2(X3Σ −  g , v = 1) production quantum yield per one act of O3 photolysis in the Hartley, Huggins, Chappuis and Wulf bands (200–900 nm). We demonstrate that the RQO weakly depends on latitude and season, and suggest a parameterization formula for the altitude dependence of this parameter. We show the application of RQO to H2O retrievals from the 6.3 µm broadband radiance measured by the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER)/Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) instrument that has been performing remote sensing of the Earth's atmosphere in the 13–110 km altitude range from 2002 onwards.


In this expository paper we describe an unifying approach for many known entropies in Mathematics. First we recall the notion of semigroup entropy h_S in the category S of normed semigroups and contractive homomorphisms, recalling also its properties. For a specific category X and a functor F from X to S, we have the entropy h_F, defined by the composition of h_S with F, which automatically satisfies the same properties proved for h_S. This general scheme permits to obtain many of the known entropies as h_F, for appropriately chosen categories X and functors F. In the last part we recall the definition and the fundamental properties of the algebraic entropy for group endomorphisms, noting how its deeper properties depend on the specific setting. Finally we discuss the notion of growth for flows of groups, comparing it with the classical notion of growth for finitely generated groups.

There is provided a method for measuring a user-centric audience content. A given terminal (90) used by at least one panelist a given focus, performs the following steps: it registers (4-I) as terminal panelist with an audience measurement server; it receives a label (1) previously associated with the content, or it combines a marker to content; during consumption of content by the given terminal, the tag transmits (413, 414) of the consumer message server each including a unique identifier marking stored by the given terminal, and at least one consumer information relating to the consumption of content at a determined instant; and at least once, it transmits (49) to the server a notification message including the unique identifier for marking, a unique ID of the given terminal (if it is not coincident with the unique identifier marking) and panelist list (s) said (s).


SUMMARY Defoliation of well-stocked, 10–12-year-old P. parula, and younger E. saligna/grandis and E. cloeziana standsby the larval stages of a geometrid moth Buzura edwardsi Walker, recently indicates that this is a potentially important forest pest in the Melsetter district, one of the major areas of pine and eucalypt afforestation in Rhodesia. Field observations of the habitsand life cycle of the pest and the damage it causes are recorded, as well as its biological control which, in normal seasons, appears to be adequate in keeping infestation at tolerable levels. However, the necessity is stressed for immediate specialist investigation into effecting permanent control of this economically important forest pest, preferably by biological means.


Be honest. Deep down, most mathematicians probably accept "mathematical social sciences" as an oxymoron. I did — until after examining this area more seriously. Comfortable in my own research emphasizing the Newtonian N -body problem, I probably would respond to news that someone was working in, say, mathematical economics with a polite, "That's nice," where this noncommittal comment carried the tacit, private, yet universal translation among mathematicians, "What a 'wishy-washy' topic! Guess he can't do real mathematics." But approaches and events have significantly transformed fields. The social sciences have changed to the point that it now is appropriate to re-examine our beliefs. Of course, it always is possible to find disturbing examples. But when conducting a serious search of some of the social sciences, expect to discover that our thoughts are so dated that many (maybe not all) of them qualify as outright prejudices. Times truly are changing. We just have to review what has been happening in our field of mathematics over the last thirty to forty years to recognize that this probably is the most exciting period in history to be a mathematician. New areas and topics are constantly developing. New approaches now permit mathematical advances which would have been met with skepticism only a decade or so earlier. We are experiencing a fascinating time when even major named problems keep falling. Much more is happening. Mathematical excitement extends beyond the doors of a mathematics department to include a significant increase in the mathematical sophistication and advances of other disciplines. We all have a sense of this; all of us can point to another discipline — computer science, physics, biology, engineering — and recognize important, challenging mathematical concerns. But, the social sciences? The point of these lectures is to indicate that the social sciences can be the source of a considerable mathematical interest. A major reason is that while the social sciences always have addressed deep and serious societal concerns, often the heaviest mathematical tool outside of statistics has been elementary calculus. This is changing; more and


Social networks are colonised by a culture of confession that turns teenager privacy into a commodity to achieve recognition and social acceptance. This display accelerates the porosity of the boundaries between the public and the private and feeds surveillance capitalism. The aim of this systematic review is to examine the empirical evidence on the public-private interaction of teenagers' contributions to social networks in the last 5 years in databases: Eric, Scopus and Web of Science. Based on the Prisma Statement, the initial search produced 1449 documents, of which 81 were included in the final analysis after the application of exclusion and inclusion criteria and the purging of duplicates. The results show a field of study developed with a decreasing trend in production in recent years, knowledge gaps and discordant findings. It is concluded the need to build solid knowledge and initiate new lines in the study of the issue in order to understand the exhibition of teenagers in social networks. It is points out the urgency of a training based on their own media practices and in digital literacy for a broad understanding of online privacy.


For medium sized projects (5-20 developers), Doug suggested starting with a small (1 5 developers) team to stabilize requirements and develop the core object model. This core team can then go on to become the system architect and team leaders for the expanded team. This allows the project to get running early and then grow the function base system. Code management tools are definitely required with this size team.


Livestock keepers and the stakeholders who support them through research, policymaking, and program implementation need more support to adapt livestock systems to the growing challenges of climate change. In sub-Saharan Africa alone, there are over 300 million impoverished people who rely on livestock as a key primary or even sole productive asset (Herrero et al. 2014). For many of these people, livestock also serve as their financial backup in times of economic stress. Similarly, Asia is home to over half of the world's total livestock population, including pigs, chickens and ruminants. Of these, 50–70% are kept by smallholder producers (Ahuja 2013). In recent decades, the number of livestock in Africa and Asia have maintained growth trends in response to increasing consumer demand and rural livelihood needs, trends which are expected to continue into the foreseeable future. Livestock systems in both regions are characterized by significant vulnerabilities to climate change impacts.

ABSTR•CT.--We surveyed a Whooping Crane (Grus americana) genomic library enriched for repetitive clones, and isolated a clone whose insert hybridized stringently to a repeated-DNA family in the genomes of Whooping Cranes, but not Sandhill Cranes (G. canadensis). This tandem sequence, repeated approximately 500 times in the Whooping Crane genome, displays taxon-specific properties uggesting that the Common Crane (G. grus) is the Whooping Crane's nearest living relative. Low-stringency hybridizations with this repeat produced conserved patterns in all cranes except crowned-cranes (Balearica), which indicates an early divergence of the crowned-cranes and the remaining cranes. Sequence and DNA-hybridization analyses imply that this repeat is a satellite sequence of similar complexity and organization to the primate alphold DNA-sequence family, which also has chromosome and species pecificity.

An extended four-component Bogoliubov–de Gennes equation is applied to study the Josephson effect in ballistic limit between either two iron-based superconductors (SCs) or an iron-based SC and a conventional s-wave SC, separated by a normal metal. A 0–π transition as a function of interband coupling strength α is always exhibited, arising from the tuning of mixing between the two trajectories with opposite phases. The novel property can be experimentally used to discriminate the s ± ?> -wave pairing symmetry in the iron-based SCs from the s ++ ?> -wave one in MgB2. The effect of interface transparency on the 0–π transition is also presented. The 0–π transition as a function of α is wholly distinct from that as a function of barrier strength or temperature in recent theories (Linder et al 2009 Phys. Rev. B 80 020503(R)). The possible experimental probe of the phase-shift effect in iron-based SC Josephson junctions is commented on as well.


Sir, We appreciate Kaushik for raising such an important issue. Clinical and basic science research has been neglected as a part of postgraduate surgical training in India. The authors attempted to gauge contribution by Indian surgical fraternity to academic world. When one observes the methods they have included only two key words i.e. 'India' and 'surgery'. It is a possibility that authors may have missed a few publications during their search strategy. However authors' message is not disputable, irrespective of their search strategy. We do not deny the fact that there is a serious problem in Indian Surgical Community when it comes to research and development. It is a shame that trainees developing excellent clinical and surgical skills remain devoid of research opportunities. The fundamental problem with publications from Indian surgical community is lack of research infrastructure and institutes overburdened with clinical responsibilities. Needless to say, funding is a major problem in conducting quality research. It is therefore not surprising that most of the surgical literature from Indian journals is based on small series and case reports. There is not much scope for quality research during a three year post-graduate surgical training. International surgical literature is dominated by the Western World. The U.S. is by far the highest-ranking region in publications in the top 50 biomedical journals even after adjusting for population size, gross national product and other factors. Canada and Western Europe share the second place while the rest of the world is far behind. Along with all other problems it is difficult to meet with the research standards of the Western World. The problem is further compounded by the surgical disease profile in India. For example surgical issues particularly common in India (for example: tuberculosis, amoebiasis etc) are not common in the west and vice versa. This has a significant impact on citations of Indian publications. The journals with the highest impact factors generally have a lower proportion of articles which are never cited and Indian literature struggles when it comes to high impact factor journals. Publication in a peer-reviewed journal is a crucial end-point for surgical trainees to progress in their career. General surgical journals form an important "translational bridge" for the success of published laboratory research into clinical application. Clinical research is difficult because of non uniformity in the surgical practice even in a single institution and most of the surgical units work without any fixed protocols. In their conclusion author has requested that while publishing papers we should cite Indian authors and Indian publication. This seems like asking for a favour rather the recognition of quality of work. Many of the Indian journals are not peer reviewed and not Pubmed-indexed, this makes potential Indian authors to publish their good quality work in other peer-reviewed journals. In conclusion, this is a serious issue and Indian surgical community needs to generate good quality research that is published in Indian journals to avoid their extinction from international surgical literature.


Professionalism and how it is to be acquired should be a focus of every teacher education program. Despite the significant role professionalism plays, a lack of a universally accepted method of assessing professionalism has been challenging to teacher education programs. This paper examines professionalism and presents characteristics specific to the teaching profession based on Hart and Marshall's (1992) fundamental characteristics of a profession and the work of Vollmer. Each of these fundamental aspects is addressed as well as the relevancy to fostering a professional culture in teacher education programs.


This study examines the sources of social pressures influencing the administrative decision-making process of Jordanian sports federations for self-defense sports. The study's objectives are to identify these sources and determine if there are statistically significant differences in their impact based on the type of game. The researchers used a descriptive survey method, with a sample of 43 individuals from Jordanian self-defense sports federations boards. A questionnaire was developed to measure the sources of social pressures, consisting of 32 items. The results indicate that the level of pressure sources was intermediate overall, with some items ranking higher or lower in importance. The study also found variations in the sources of pressure based on the type of game, with kickboxing showing greater significance than karate. These findings shed light on the social pressures affecting administrative decision-making in Jordanian sports federations and provide insights for better understanding and managing these influences in the future.

Four air quality requirements from the U.S. Environmental Protection Agency (EPA) include the: (1) National Ambient Air Quality Standards (NAAQS), (2) Cross-State Air Pollution Rule (CSAPR), (3) Mercury and Air Toxics Standards (MATS), and (4) Boiler MACT. The NAAQS specify maximum ambient concentrations of six air pollutants, while CSAPR and MATS require significant reductions in pollution from certain electric generating units (EGUs) – the country's largest sources of SO2 and of mercury emissions, and the largest stationary sources of NOX emissions. Boiler MACT sets emissions limits and other requirements on industrial, commercial, and institutional boilers. Each of these regulations offers an important opportunity to expand the use of well-known, proven, and cost-effective energy efficiency 1 . With the NAAQS, states can use efficiency as a direct strategy to achieve emissions reductions necessary for meeting the standard. Under CSAPR, a market-based emissions trading program, power plants that improve their generating efficiency will correspondingly reduce the tons of SO2 and NOX they emit, thereby reducing the number of CSAPR allowances required to surrender for compliance 2 . MATS includes alternative output-based standards for existing sources and primary emission standards for new sources, including provisions for combined heat and power (CHP), or cogeneration units. In addition to opportunities for new-source efficiency improvements within the MATS rule, recent EPA power-sector modeling illustrates the important complementary benefits of state policies to support demand-side efficiency improvements. These benefits include lowering total compliance costs for MATS, reducing ratepayer bills over the long term, and in some cases, delaying or avoiding the need for equipment upgrades or new construction of generating facilities and emissions controls. The Boiler MACT 3 also includes alternative output-based standards that recognize improvements in boiler efficiency (including use of CHP), as well as a provision for boiler tune-ups and facilitywide energy assessments in affected facilities. The purposes of this paper are to: briefly describe these regulations; document the opportunity with each regulation to employ efficiency; and describe the steps EPA is taking to help state and municipal governments plan for and use energy efficiency as a strategy to reduce emissions and improve air quality. The paper concludes with several no-regrets options that these jurisdictions can consider.


In recent years, as people pay more and more attention to improving their theoretical knowledge, they can ensure online learning anytime and anywhere by adopting mobile learning. This paper mainly analyzes and studies the concept of mobile learning, and briefly describes the online and offline types of mobile learning. Finally, a comparative analysis is made on each seed mode involved in online type and offline type, so as to effectively ensure that the appropriate learning mode is selected according to the comprehensive consideration of learning content, learning demand, learning situation and other factors during mobile learning.


Association of organic carbon (OC) with reactive iron (FeR) represents an important mechanism by which OC is protected against remineralisation in soils and marine sediments. Recent studies indicate that the molecular structure of organic compounds and/or the identity of associated FeR phases exert a control on the ability of an OC–FeR complex to be extracted by the citrate–bicarbonate–dithionite (CBD) method. However, many variations of the CBD extraction are used, and these are often uncalibrated to each other, rendering comparisons of OC–FeR values extracted via the different methods impossible. Here, we created synthetic ferrihydrite samples coprecipitated with simple organic structures and subjected these to modifications of the most common CBD method. We altered some of the method parameters (reagent concentration, time of the extraction and sample preparation methods) and measured FeR recovery to determine which (if any) modifications affected the release of FeR from the synthetic sample. We provide an assessment of the reducing capacity of Na dithionite in the CBD method (the amount of Fe reduced by a fixed amount of dithionite) and find that the concentration of dithionite deployed can limit OC–FeR extractability for sediments with a high FeR content. Additionally, we show that extending the length of any CBD extraction offers no benefit in removing FeR. Moreover, we demonstrate that for synthetic OC–FeR samples dominated by ferrihydrite, freeze-drying samples can significantly reduce OC–FeR extractability; this appears to be less of an issue for natural marine sediments where natural ageing mechanisms may mimic the freeze-drying process for more stable Fe phases. While our study is not an all-inclusive method comparison and is not aimed at delivering the "perfect" extraction setup, our findings provide a collected summary of critical factors which influence the efficiency of the CBD extraction for OC–FeR. As such, we provide a platform from which OC–FeR values obtained under different methods can be interpreted and future studies of sediment carbon cycling can build upon.


Objective: Our purpose was to determine whether unexplained elevations in maternal serum human chorionic gonadotropin (hCG)in the second trimester is associated with an increased risk of preeclampsia. Methods: Between April 1992 to April 1995, 610 pregnant women undergoing second trimester triple marker screening for Down's syndrome who were delivered at our institution were included to the study. 81 women with an hCG level greater than 2.0 multiples of median (MOM) served as the study group and 481 women with hCG levels


Abstract Purpose: To study factors influencing lipid changes after switching to atazanavir (ATV) and the effectiveness of ATV in maintaining virus suppression. Methods: Retrospective cohort study in patients with viral suppression, comparing patients switching to ATV with those continuing combination antiretroviral therapy (cART). Outcome measures were 48-week total (TC), high-density (HDL) and low-density lipoprotein (LDL) cholesterol, and triglycerides (TG) changes, stratified for dyslipidemia and lipodystrophy and virological failure (time to first of two consecutive detectable HIV RNA). Results: 225 patients switched to ATV (193 [85.8%] RTV boosted), and 3120 continued cART. In patients with baseline TC >6.2 mmol/L, those switching had greater mean (95% CI) TC decreases compared to those continuing cART (–1.26 [–1.63 to –0.89] and –0.54 [–0.64 to –0.44] mmol/L, p = .002). Likewise greater TG changes were observed in patients with high (>2.3 mmol/L) baseline TG (–1.44 [–2.05 to –0.83] and –0.54 [–0.70 to –0.38] mmol/L, p = .002). Effects were seen irrespective of presence of lipodystrophy. Patients switching to ATV had virological failure more often (17/224 [7.8%]) than those continuing cART (73/3100 [2.4%], p < .0001). Conclusions: Patients with virological suppression, including those with lipodystrophy, may benefit from switching to ATV with lipid profile improvement, especially if baseline lipid levels are high. This should be balanced against a possible higher virological failure risk.


encompasses a range of perspectives, including literary studies, anthropology, publishing studies, the history of the book, and art history. In addition, many of the chapters are based on archives and collections that have not been explored in the past. The book shed light on the historical discrepancies in print culture – racial, linguistic, gender-based, and geographical – and helped explain some of the existing inequities in global knowledge access and production. Additionally, the volume contributed to current debates and opened up new and intriguing ways to deepen the study of postcolonial literature and African book history. This book demonstrates that the history of cultural printing in Southern Africa is relatively well documented, albeit with some gaps that may be further explored. However, there are specific types of texts that have gotten less attention and therefore should be investigated further: non-literary, non-fiction works of all kinds, such as the historical development of scholarly publishing, textbooks, and schoolbooks.

Abstract
 Information systems constitute a key feature of the European Composite Administration. In the Food and Feed sector, the European Union has established a Rapid Alert System for Food and Feed (RASFF) obliging the Member States to exchange information on food- and feed-related risks to public health, thus enabling them to take action in case of food safety risks resulting from the free movement of these products within the European Union. Such information systems pose a particular challenge for effective legal protection since undertakings seeking to challenge the information exchange or measures resulting from it because of e. g. incorrect information are confronted with a multitude of actors, legal orders and systems of judicial protection. Against this background, the article explores the RASFF's design and ist functioning, notably the role of the various actors on national and EU level, and analyses the issues of primary and secondary legal protection in case of incorret alert notifications. Moreover, on the basis of these findings, general conclusions for designing EU information systems – relevant also beyond the Food and Feed sector – will be drawn.


Psychologists and philosophers have recently been exploring whether the mechanisms which underlie the acquisition of 'theory of mind' (ToM) are best charac- terized as cognitive modules or as developing theories. In this paper, we attempt to clarify what a modular account of ToM entails, and why it is an attractive type of explanation. Intuitions and arguments in this debate often turn on the role of develop- ment: traditional research on ToM focuses on various developmental sequences, whereas cognitive modules are thought to be static and 'anti-developmental'. We suggest that this mistaken view relies on an overly limited notion of modularity, and we explore how ToM might be grounded in a cognitive module and yet still afford development. Modules must 'come on-line', and even fully developed modules may still develop internally, based on their constrained input. We make these points con- crete by focusing on a recent proposal to capture the development of ToM in a module via parameterization.


In response to the letter, we agree that noncompacted cardiomyopathy is an enigmatic condition with several pathophysiological aspects not completely elucidated, making its characterization by the use of the major diagnostic tools, echocardiography and cardiac magnetic resonance imaging, difficult. Thus, as highlighted in the case report, the use of both methods has been postulated as often required to either confirm or exclude the diagnosis of that condition.


All too often, critics, historians, and music analysts draw upon the aesthetic and analytic language of composition to describe and account for performed interpretations. This article explores the inequities and challenges that derive from this borrowing of language. Yet a study of Ernst Levy and his recorded performance of Brahms, however, reveals how compositional aesthetics can also be appropriated and repurposed to new creative ends.


We have aimed to investigate the presence of peripheral and autonomic neuropathy in individuals who had been diagnosed with impaired glucose tolerance (IGT) on the basis of an oral glucose tolerance test, by comparing with age‐matched healthy subjects with an oral glucose tolerance test (OGTT) in normoglycemic ranges.


Fabrics made from cotton, cashmere, flax, hemp, ramie, jute, and wool fibres, have been used to investigate and analyze the prickle comfort properties of fabrics worn as garments. Physical properties include single-fibre critical load, compression and bending modules, which greatly affect the fabric physiological comfort. The fibres are tested using a 'fibre axial compression-bending analyzer'. The behavior mechanisms of single-needle fibre are also analyzed, evaluated, and explained using fibres critical load, fineness, and protruding length. Physical and neuro-physiological basis for prickle sensation force from single-needle fibre depends on its bending modulus and axial compressive behavior. This experimental work shows that the bending modulus of ramie, jute, and wool fibre is significantly high as compared to other fibres. Thus, high prickle values of ramie, jute and wool fibres make them more uncomfortable due to the cross-section parameters and bending modulus of the single fibre needle. It is observed that the prickle feeling comes from the axial-compressive behavior and the number of effective fibre needles protruding from worn fabric surface. Therefore, prickle sensation aroused during skin–fabric contact is mostly related to the fibre and surface roughness characteristics of fabrics, and the effect of the fabric material on prickle is found to be more.

Accretion in active galactic nuclei (AGNs) is obscured by ga s and dust that surround the central super-massive black hole. This intervening matter efficien tly absorbs the primary photons up to X-ray energies, while at higher energies ( > 15 keV) a larger fraction of photons pierces through. At thes e nergies most sensitive large area surveys are performed by the two coded-masks tele scop s theINTEGRAL Soft Gamma-Ray Imager (IBIS/ISGRI) and theSwift Burst Alert Telescope (BAT). However coded-mask detectors suffer from heavy systematic effects (errors) preventing them from reaching their theoretical limiting sensitivity. Here we show that BAT and IBIS/ISGRI observations can be combined with resamp ling, merging, and cross-calibration techniques that minimize the errors and produce the nowadays deepest la rge area survey at soft gamma-rays. This survey of our virtual new gamma-ray mission allows detecting the obsc ured AGNs. It extends over a wide sky area of 6200 deg2 sampling 113 sources. The flux sensitivity is 2-4 times bette r than current parent surveys. We discuss the evolution of AGNs through the luminosity function. Our resu lt are then compared to other missions. We discuss also the expected results when applying this survey to the en tire extragalactic sky.


Selection for increased muscling in cattle has great potential to increase the value of the carcase and improve profitability of the beef industry by increasing retail beef yield. Carcase traits are usually considered in the context of slaughtered animals, but the overall productivity and profitability of the herd is very dependent on the fertility of the breeding unit. Age at puberty is an important parameter of fertility as it sets the earliest possible start to a female's reproductive life, which in turn impacts on her lifetime performance. We assessed early reproductive potential in Angus heifers in a herd selected for increased or decreased muscularity.

The great lability of man's glucose reserves as shown by the decreases in liver glycogen both during short starvation, decreased intake of carbohydrate or as an effect of trauma shows the importance of carbohydrate administration both in the normal man and in the treatment of trauma. Even if a relative intolerance to glucose is seen in the post‐traumatic phase, it seems reasonable to use glucose possibly together with insulin as the basic calorie supply. The most important reason for this is that during hypoxia, which can readily occur, the only useful fuel is glucose transported via the blood or stored in the tissues as glycogen.


In this paper, we study the fabricated report with false votes attack and the false votes on real reports attack in wireless sensor networks. Since most of the existing works addresses the first attack while leaving an easy way for the attackers to launch the second attack, we propose a probabilistic voting-based filtering scheme (PVFS) to deal with both of them simultaneously. On the basis of the en-route filtering scheme, PVFS combines cluster-based organization, probabilistic key assignment, and voting methods. Through both analysis and simulation, we demonstrate that PVFS could achieve strong protection against both attacks while maintaining a sufficiently high filtering power.


Background Critical care survivors face physical, psychological and socio-economic burdens. Peer support is acknowledged as a way individuals can face, accept and overcome the challenges arising from a stressful event. We sought to examine the provision and benefits of peer support to critical care survivors in the UK. Method We distributed a survey, devised by the patients and relatives committee of the Intensive Care Society and ICUsteps, to contacts in 163 UK Trusts/hospitals with critical care departments. The benefit to individuals was assessed by seeking the views of attendees of two support groups. Results A response was received from 91 (56%) of the critical care departments. Of these, 46 (48% of respondents) have patient support groups. Our analysis of comments from 30 people is that support groups greatly benefit service users and staff. Conclusions Attendees of patient support groups gave highly positive comments about the service yet provision of patient support groups in the UK is not universal. Recommendations We make a series of recommendations for consideration by UK health care providers.

The study of seasonal and Iong-term variations of wind power production is based on wind power production statistics and long-term meteorological wind data from weather stations on the coast of Finland. Presently the wind energy production estimates are made for yearly average production only. The methods have been developed to assess the average monthly production and the range of variations for an individual month. According to the meteorological stations' wind speed measured along the Finnish coastline, the yearly wind speed variations are 515 '?Ao(standard deviation/average calculated fi-om the yearly mean wind speeds). Variations of the monthly mean wind speeds in summertime are of the same order of magnitude as the yearly variations, whereas the variations are more than 20 0/0 during the winter months. The yearly variations of wind power production resulting from wind speed variations are 1030 O/O. The monthly variations of wind power production are below 30 YO in summer months and up to 60 0/0during winter months. Index series of average monthly wind power production has been constructed for both the southern and western coasts of Finland. For this the linear relation between monthly mean wind speed and monthly mean wind power as measured in Hailuoto, Finland has been used. In addition to this, the WAsP-method for wind power production estimates has been developed, in order to estimate the monthly average wind power production for a specific site and wind turbine. The wind power production of an individual month can vary a lot especially in wintertime. The statistical estimation gives ranges of variations up to + 90 '?ZOof the average production. So, in practise it is impossible to predict the production of an individual winter month. The range of the monthly variations is lower in summertime.


We identify a general criterion for detecting entanglement of pure bipartite quantum states describing a system of two identical particles. Such a criterion is based both on the consideration of the Slater‐Schmidt number of the fermionic and bosonic analog of the Schmidt decomposition and on the evaluation of the von Neumann entropy of the one‐particle reduced statistical operators.

Background: Despite the emergence of potentially prophylactic vaccines, COVID-19 transmission poses a persistent threat to healthcare providers (HCPs) communities. Aim: Assess the progress in the knowledge and attitudes of HCPs of Armed Forces Hospital Wadi Al Dawasir (AFHWD) toward COVID-19 measures and vaccines perception. Methods: A questionnaire was distributed online, 09-10, 2021, to achieve study aim. SPSS-22.0 software was used for the analysis;ANOVA;t-test used for comparing quantitative variables;.2 for categorical data;level of materiality set to 0.05. Results: Out of 149 HCPs, 38 (25.5%) were "physician" 44 (29.5%);"nurse";31 (20.8%) " allied health" 11 (7.4%)" pharmacist";25 (16.8%);"other"'. HCPs averaged 39.3 +/- 9.2y of age. Overall score (84.3%) greater than cutoff, set to 70%, also greater than that assessed earlier (69.5%) was achieved (p=0.005). The higher profession the higher score (p<0.05). "Age";"clinician";"infection prevention and control (IPC) training;"COVID-19 infection", were significant score predictors. COVID-19 "all knowledge" (general and IPC, combined) = 79% exceeded cutoff (70%), (p<0.001);also exceeded that identified earlier (69.6%), (p<0.001). The IPC perception score behaved likewise: 86.1% vs. 70%, 86.1% vs. 71.6%, (p<0.001), respectively. An overall vaccine response (68.3%) comparable to cutoff was verified (68.3%), (p=0.08). Most (86.6%) HCPs accepted a COVID-19 vaccine;73.2% were vaccine confident;23.3% of those immunized were concomitantly vaccine hesitant (p = 0.012). "Age" and "clinician" predicted vaccine response variability. Conclusion: Findings imply an ongoing improvement of the HCPs' responses on COVID-19 requirements. Continued education and adherence with updated protocols provide utmost protective environment for the HCP staff against COVID-19 consequences.


The beginning of the information age is associated with the intensive development of fundamentally new information technologies. On their basis, the screen culture is formed generating the formation and development of the virtual reality sphere. This artificially created space is a consequence of scientific progress, the result of technological innovations. Virtual reality is currently perceived as an integral part of social life, as a socio-cultural environment, as a living space of a person. In turn, the virtual environment affects the man himself. The impact of this sphere is one of the central moments in the profound transformations of the lifestyle and mentality of our contemporary. In this regard, there are complex problems associated with understanding the expansion of screen technology, with the paradox of the existence of artificial worlds. Virtual reality is becoming more and more widespread in various fields, including art, especially cinema, gaming and entertainment. Being an integral attribute of modern civilization, it has a contradictory, paradoxical character. It is marked by an anthropic principle, a variety of interpretations, and polarization of social assessments. The article considers its genetically mediated features, ontological, social, axiological and communication aspects. As a result of this analysis, conclusions are drawn about the emergence of new trends in social life and in art.

Amorphous silica-alumina (ASA) is widely used as a solid acid catalyst or as a carrier for well-dispersed metal sulfide or metal catalysts. They are often involved in hydrocracking catalyst formulations, especially so when the aim is to produce middle distillates from heavy oil fractions. With increasing demand for diesel and kerosene balanced acidity in these catalysts to combine high conversion with high middle distillates selectivity is crucial. An important advantage of amorphous silica-alumina as an acidic catalyst is its open texture with substantial mesoporosity as compared to zeolites that typically suffer from diffusion limitations when bulky hydrocarbons need to be converted. Strongly acidic supports also cause excessive coke formation and overcracking of the feedstock resulting in lower middle distillate yields. Therefore, the use of ASA as the acidic component in bifunctional hydrocracking has become important. Although moderate acidity is important for ASA supports, accurate control of the acidity is hampered by a lack of understanding about the origin of acid sites in these materials and how they are formed. Regarding the former, the nature of the Bronsted acid sites (BAS) has not been unequivocally established. The more widely shared opinion is that the Bronsted acidity derives from tetrahedral Al3+ in the silica network, as initially proposed by Thomas and Tamele in the late 1940s. This proposal however has remained inconclusive. Alternative explanations for the acidity have been also been proposed. These include Lewis acidic Al ions substituting for protons of surface silanol groups and the higher acidity of silanol groups in the presence of neighbouring aluminium surface atoms The other reason that surface acidity of ASAs is understood to a much lesser extent than that of zeolites relates to the complex surface composition of these mixed oxides. ASAs are made by co-precipitation, co-gelation or grafting processes and in nearly all cases, the resulting materials contain a non-random distribution of aluminium in silica. The present project was thus undertaken with the aim of (i) synthesizing a set of ASA materials by as controlled a method as possible for use in catalytic activity studies and (ii) to learn about the genesis of Bronsted acid sites in ASAs and their strength. The synthesis method chosen was a well-defined variant of grafting, viz., homogeneous deposition-precipitation. The entire process of the deposition of aluminium on silica and subsequent calcination was followed by 27Al NMR spectroscopy . The study showed that the aluminium species in the dried precursors is a function of pH and starting aluminium concentration. At pH of 3 and at low aluminium concentration, the surface mainly consists of tetrahedral and octahedral aluminium species. Under these conditions an increase in pH gives mainly rise to tetrahedral aluminium species on the surface. This is attributed to the further condensation reaction occurring with the surface silanol groups. However, with increasing aluminium concentration, the deposition mechanism involves reaction of aluminium species in solution with species already grafted on the surface. This results in the formation of polymeric aluminium species. In addition, at higher aluminium concentrations some precipitation of aluminium hydroxide also occurs. When the dried precursors are then calcined, redistribution of the grafted aluminium species occurs, mainly with a small fraction of aluminium diffusing into the silica matrix thereby resulting in Bronsted acid sites. The formation of Bronsted acid sites upon calcination was also evidenced by n-alkane hydroconversion activity tests, which requires the presence of strong acid sites. From this systematic study the surface of amorphous silica- alumina could be described as consisting of three different species, namely a pure silica-alumina phase that originates from isolated aluminium grafted onto the silica surface, domains of aluminium oxide and a small fraction of aluminium in the silica network responsible for the strong Bronsted acidity. By following the selective H/D exchange of acidic hydroxyl groups in aluminosilicates by IR spectroscopy clear evidence was provided for the existence in ASAs of BAS comparable in strength to the bridging hydroxyl groups in zeolites. The method is able to distinguish various types and strengths of strong BAS in luminosilicates (zeolites, clays, ASAs) such as enhanced acidic sites in steam calcined faujasite zeolites. By carrying out the H/D exchange under conditions under which zeolites selectively exchange their bridging hydroxyl groups, weak bands were observed at 2630 and 2683 cm-1 in the deuteroxyl region of ASAs. By quantification it follows that the concentration of strong BAS in ASAs is 2-3 orders of magnitude lower than in zeolites. A number of techniques (CO IR, pyridine IR, alkylamine TPD, Cs+ and Cu(EDA)22+ exchange, 1H NMR and m-xylene isomerization) was used to validate the H/D exchange FTIR results and provide further insight into the heterogeneous surface composition of ASA. The results show that the surface contains both Bronsted and Lewis acid sites of varying acidity. The number of strong Bronsted acid sites of zeolitic strength is very low (<10 µmol/g). Careful interpretation of IR spectra of adsorbed CO and pyridine confirmed that the surface contains only very few of such sites. Other methods suitable to estimate strong BAS involve an adaptation of the well-known decomposition of alkylamines and titration of such sites by a base during m-xylene isomerization. These sites originate from Al substitutions in the silica network. Besides, the surface contains between 50-150 µmol/g of a weaker form of BAS, which can be easily quantified by CO IR. Cu(EDA)22+ exchange also appears to probe weak BAS. The structure of these sites remains unresolved, but some of the results suggest that these are related to paired sites, involving the interaction of strong Lewis acid sites with silanol groups. In addition, the surface of ASA contains two forms of Lewis acid sites: (i) a weaker form associated with segregated alumina domains and probably containing five-coordinated Al species that make up the interface between such domains and the ASA phase and (ii) a stronger form which are lower coordinated Al sites grafted to the silica surface.


7509 Background: NTX-010 is a naturally occurring replication-competent picornavirus with potent and selective tropism for SCLC tumor cells expressing neuroendocrine markers. A phase I study of NTX-010 showed evidence of antitumor activity in patients with SCLC. Methods: ES-SCLC patients (pts) with SD, PR or CR after at least 4 cycles of platinum-based chemotherapy were pre-registered to confirm diagnosis of SCLC with > 1 neuroendocrine marker by a central pathology review. Eligible pts were.randomized 1:1 to placebo (B) or NTX-010 (A). NTX-010 or placebo was administered intravenously as a 1-hour infusion in 100 mL normal saline as a single dose of 1 x1011vp/kg. Viral studies to determine distribution, clearance of the virus and the presence of neutralizing antibodies were done. The primary goal of this trial was to compare the progression-free survival (PFS) of arm A to B based on a sample size of 45 patients per arm to detect an improvement in median PFS from 3 to 5 months (m). A pre-planned interim fu...

The Story Of Golden Lock by ZHANG Ailing and The Jin Ping Mei by SMILING Person passes to mold two fresh and clear female images of CAO Qiqiao and PAN Jinlian,expresses the author's thorough thinking to the human nature that,namely passion of indulgence and human nature of durance,all demolish the person's value,and the idea of " regulate sex" comes from here.


In this paper, authors suggest a model that reflects the role played by the Web site characteristics and the previous level of satisfaction as determinant factors of trust in the Web site. Also, authors consider the moderating effects of consumers' motives and inhibitors to purchase online. Results show that satisfaction with previous purchases, the Web site security and privacy policies, and service quality are the main determinants of trust. Also, the motives and inhibitors the individuals perceive when buying online determine the type of signals they consider to trust.


The actuator has an asynchronous motor for providing a set of movements to a kinematic chain, and a reducer. An output transmission shaft is arranged for transmission of movement provided by the motor. An input part (60) and an output part (70) are movable with regard to each other with a limited play. An obstacle generation device includes a set of cams (72-1, 72-2) that is ready to create a transitory resistant force for movement transmission between the input part and output part. A control unit detects the transitory resistant force. An independent claim is also included for a method for checking operation of the electromechanical actuator.


Ethnological museums in Germany, with their entanglements of colonial history and the not always unproblematic emergence of their collections, have not only become the focus of the public since the media attention on the Humboldt Forum in Berlin: long before that they have been critizised for their neglect in addressing the colonial heritage of their collections and the lack of information on the origins of the objects. This background also applies to many of the estimated 250,000 Oceanic objects (Buschmann 2018: 198) that are stored in German museums today, which will be the focus of this article. Since the beginning of these discussions and in provenance research of ethnological museums it has mainly been the Africa collections that were at the center of attention; more and more the territories in the Pacific and the collections stemming from German colonial territories in the Pacific are now being explored.

The effects of various radiations on the potency and keeping qualities of digitalis were studied. The official tincture of digitalis was used in our experiments. The activity of the preparations was tested in two ways: on the one hand by the cat method, and, on the other hand by the new phytopharmacological method developed by the authors and described elsewhere. 1 The effect of ultra violet rays was studied with a Krohmayer water-cooled mercury vapor quartz lamp and with the Hanovia Alpine Sun Lamp. Tincture of digitalis was radiated with these machines in quartz containers and in pyrex and ordinary glass test tubes for various length of time. The effect of ultra violet radiation was to produce a rapid deterioration of the tincture. Radiation for one hour with the Krohmayer lamp or with the Alpine Sun Lamp of digitalis in a quartz tube produced as much as 30 per cent deterioration in some cases. An analysis of the various rays short and long, in respect to their activity on digitalis, showed that the shorter wave lengths, that is, those less than 2800 angstrom units were more active than the longer ultra violet rays. Digitalis in pyrex vessels was affected deleteriously to a greater extent than digitalis contained in ordinary glass containers. In addition to the ultra violet rays obtained from the mercury lamp the effect of still shorter radiations on digitalis was studied. Samples of tinctures were exposed to x-rays, to radium directly and to radium emanations. It was found that x-rays and the radium radiations produced destructive changes in the tincture as far as pharmacological potency was concerned. The effect of heat radiations was also studied and it was found that exposure to temperature of 39° for 24 hours or longer, produced considerable deterioration in the tinctures which were tested by the methods described above.


A prominent jurist once described the law as a "seamless web." This description of linked knowledge actually applies to all fields of scholarship and investigation, and it is not only lawyers who experience the need to move through the library constantly, each open text citing another or suggesting another avenue of inquiry. The pile of open books on the library table, and the constant recourse to catalogue and stacks, epitomize the image and the process of textual research, both for the advanced scholar and for the school-child writing her first essay. Computers clearly have the capacity to enhance the quality of our lives, but in my opinion their contribution to library reference work lies chiefly in this: to liberate us from the "up-and-down-and-fetch" mode of research as well as the "scissors-and-paste" method of text revision. This liberation is promised today in the hypertext features of all Windows-based or icon-clicking applications in use now, particularly with the incorporation of graphics and images, be they decorative or illustrative, from Netscape creatures to art, archaeology, or architecture.


We report on a comparison of electroluminescence (EL) spectra measured in plan view versus on a cross-sectioned face of the same AlGaN/GaN device for the first time. Because EL emission can be more intense under optically opaque metal structures, a difference was expected. We observed and quantified the difference in EL intensity and the extracted electron temperature. We discuss the effect on the rate of proposed channel hot-carrier degradation. Device simulations were used to gain insight on the expected spatial distribution of hot electrons within the channel. Last, spectra acquired on the cross-sectioned face were found to be free of interference artifacts common in plan view that could complicate the interpretation of the spectral data.


Bamboo flour was modified by self-made polyethene wax grafted maleic anhydride,and PVC/bamboo flour composites were prepared.Influences of modified bamboo flour dosage on the flame retardant and smoke suppression properties of PVC/bamboo flour composites were studied.The results show that: ① the oxygen index of PVC/bamboo flour composites is decreased with the increase of modified bamboo flour dosage;② when the dosage of modified bamboo flour is 10-50 parts,the vertical burning properties and horizontal burning properties of PVC/bamboo flour composites can reach FV-0 grade and FH-1 grade,respectively;③ both the MSD and SDR of PVC/bamboo flour composites were decreased with the increase of the dosage of modified bamboo flour.


Chitosan/silica hybrids were synthesized and shaped as microspheres, which may or may not present a core/shell structure, depending on the experimental conditions. The core is constituted by a homogeneous hybrid, while the shell is pure silica. The amino groups of the biopolymer are still accessible as active sites for heterogeneous catalysis.


We study the magnetic and superconducting instabilities of the periodic Anderson model with infinite Coulomb repulsion U in the random phase approximation. The Néel temperature and the superconducting critical temperature are obtained as functions of electronic density (chemical pressure) and hybridization V (pressure). It is found that close to the region where the system exhibits magnetic order the critical temperature Tc is much smaller than the Néel temperature, in qualitative agreement with some TN/Tc ratios found for some heavy-fermion materials. In our study, the magnetic and superconducting physical behaviour of the system has its origin in the fluctuating boson fields implementing the infinite on-site Coulomb repulsion among the f− electrons.

Pneumatic systems are widely used in automation industries and in the field of automatic control. Unfortunately, some nonlinearities are existed in these actuators. These nonlinearities have made controlling these actuators more difficult to get good dynamic performance. In this project, Receding horizon controller (RHC) is proposed to control the position and the force of a pneumatic actuator. RHC is a predictive controller that predicts the future output and decides the acting signal to reduce the future errors. The type of RHC used in this project is a state feedback controller. Three types of pole assignment observers are used in this project in order to estimate the states of the position and the force models. The observers are designed, incorporated with RHC and then compared in terms of their estimation errors. The implementations of RHC and the observers are carried out using MATLAB/Simulink. Using a data acquisition system (DAQ) real time control between the computer and the pneumatic actuator is established. The RHC shows good control performance both in controlling the position and the force. The experimental and the simulation results of RHC are compared to validate the controller. To further evaluate the RHC controller, its results are compared with other controllers done in previous works, and it is found that RHC has some advantages over these controllers in terms of the control performance criteria.


We determine the masses and decay constants of the pseudosca lar mesonsBs andBc, and also the masses of the vector mesons Bs andB ∗ c, in quenched lattice QCD with exact chiral symmetry. For 100 gauge configurations generated with single-plaquette a ction atβ = 7.2 on the 323×60 lattice, we compute point-to-point quark propagators for 33 quark ma sses in the range 0 . 1≤mqa≤ 0.85, and measure the time-correlation functions of pseudoscala r and vector mesons. The inverse lattice spacing and the charm quark bare mass are determined using th e mass and decay constant of ηc(2980). The bare masses of s andb quarks are chosen such that the masses of the corresponding vector mesons are in good agreement with φ(1020), andΥ(9460) respectively. Our results are: mBs = 5385(27)(17) MeV, fBs = 253(8)(7) MeV, mBc = 6278(6)(4) MeV, fBc = 489(4)(3) MeV, mB∗s = 5424(28)(19) MeV, andmB∗c = 6315(6)(5) MeV.

Purpose – This study aims to investigate the extent of influence of learning factors on tacit knowledge sharing among the public sector accountants. Design/methodology/approach – A model comprising six learning factors and their conjectured relationships with tacit knowledge sharing was derived from literature review. A self-administered questionnaire was developed and used to collect data from 203 accountants employed by the Accountant-General's Department (AGD) in Malaysia. Factor analysis was employed to confirm the model's validity, after which the hypotheses formulated were tested using multiple regression analysis. Findings – Learning factors such as training and learning opportunities have strong impact on tacit knowledge sharing, while feedback on performance evaluation, and information and communications technology (ICT) know-how and skills have moderate impact. Job rotation does not show any significant impact on tacit knowledge sharing. Research limitations/implications – This paper contributes...


Abstract : To increasing the safety factor of the space vehicles, Perspirable Skin, a new designed Thermal Protection System (TPS) was proposed by bio-mimicking the process of human sweating. Powder Metallurgy (P/M) was considered to be the best candidate method to fabricate core materials for Perspirable Skin. To perform the compaction and sintering as well as monitor the sintering kinetics/densification in the sintering, a Material Test System, MTS Insight 300 (MTS Systems Corp. USA) and a Thermomechanical Analysor (TMA), SETARAM SETSYS Evoluation 95 (SETARAM instrumentation, France), were procured. MTS Insight systems are ideal for performing standard tests such as peel, tear, sheer, tensile, compression, and flex/bend. MTS Insight 300 offers high-capacity testing capabilities up to 300 kN. Common applications include metals, ceramics, high-strength components, large fasteners, structural materials, and composite materials. Operators can easily run tests, review results, and report and archive data with the flexible and user friendly TestWorks(trademark) Testing Software. SETARAM SETSYS Evoluation 95 measures the deformation of a sample under non-oscillating stress against time or temperature with prescribed ramp/soak path. Except as a regular furnace to sinter samples with oxidization-protection environment, with its software, the SETSYS Evolution 95 can be used as a dilatometer to test many material properties, such as the thermal expansion coefficients (CTE), the softening temperature, the glass transition point and so on. The SETSYS Evolution 95 is also particularly suitable for measuring controlled-rate sintering.


Objective To explore the effects of polysaccharide nucleic acid fraction of bacillus Calmette Guerin (BCG-PNA) and specific immunotherapy (SIT) on serum IgE level and secretion of IL-4, IFN-γ, IL-12, and IL-13 in asthmatic children. Methods After treatments with BCG-PNA, SIT, and combination of these two in 36 asthmatic children, serum IgE level and the production of IL-4, IFN-γ, IL-13, and IL-12 from peripheral blood mononuclear cells were detected by ELISA. Results Both BCG-PNA and SIT could enhance the secretion of IFN-γ, IL-12, but decrease IL-4, IL-13, and serum IgE levels in asthmatic children. Combination of BCG-PNA and SIT could depress IL-13 level but increase IFN-γ level in a synergistic way. Conclusion BCG-PNA and SIT can improve Th1 response but reduce Th2 response, and regulate the balance between Th1 and Th2 in asthmatic children.


A traitor tracing scheme is a multi-user public-key encryption scheme where each user in the system holds a decryption key that is associated with the user's identity. Using the public key, a content distributor can encrypt a message to all of the users in the system. At the same time, if a malicious group of users combine their respective decryption keys to build a "pirate decoder," there is an efficient tracing algorithm that the content distributor can use to identify at least one of the keys used to construct the decoder. A trace-and-revoke scheme is an extension of a standard traitor tracing scheme where there is an additional key-revocation mechanism that the content distributor can use to disable the decryption capabilities of compromised keys. Namely, during encryption, the content distributor can encrypt a message with respect to a list of revoked users such that only non-revoked users can decrypt the resulting ciphertext. Trace-and-revoke schemes are challenging to construct. Existing constructions from standard assumptions can only tolerate bounded collusions (i.e., there is an a priori bound on the number of keys an adversary obtains), have system parameters that scale exponentially in the bit-length of the identities, or satisfy weaker notions of traceability that are vulnerable to certain types of "pirate evolution" attacks. In this work, we provide the first construction of a trace-and-revoke scheme that is fully collusion resistant and capable of supporting arbitrary identities (i.e., the identities can be drawn from an exponential-size space). Our scheme supports public encryption and secret tracing, and can be based on the sub-exponential hardness of the LWE problem (with a super-polynomial modulus-to-noise ratio). The ciphertext size in our construction scales logarithmically in the size of the identity space and linearly in the size of the revocation list. Our scheme leverages techniques from both combinatorial and algebraic constructions for traitor tracing.
