A previously undescribed tospovirus infecting tomato, capsicum and chilli in Queensland was characterised. The virus reacted with antibodies to serogroup IV tospoviruses, and the complete nucleotide sequence of its nucleocapsid protein gene indicated that it was a new tospovirus species. Sequence identities at the nucleotide and amino acid levels were <85% with recognised members of serogroup IV The virus infected test plants in five families and, importantly, overcame the Sw-5 resistance gene in tomato and TSWV resistance in Capsicum chinense accessions PI 152225, PI 159236 and AVRDC 00943. The name Capsicum chlorosis virus (CaCV) is proposed for this virus.


Objective: The present study concerns the cytotoxic activity of A. nemorosa different extracts on breast cancer cells (MCF-7) and normal cell lines (HFFF). Methods: Different extracts of aerial parts of A. nemorosa were prepared using Soxhlet apparatus. The cytotoxicity of samples was assessed by MTT assay on breast cancer cells (MCF-7) and noncancerous cells (HFFF) with different concentrations of extracts in 24 and 48 hours. The most potent extract was fractioned and cytotoxic activity of fractions was considered, As well. A flow cytometry (annexin V/PI) assay has been used for detecting the mechanism of cell death in sample treated cell lines. Moreover, for clarifying volatile components of n-Hexane extract and its 80% and 100% VLC fractions were subjected to GC-MS apparatus. Results: Results indicated that n-Hexane extract and its 80% and 100% VLC fractions exhibited a significant (p<0.001) inhibitory effect on the growth of the MCF-7 cell line compared to the control group. Meanwhile, flow cytometry analysis revealed that potent extract caused cell death through necrosis and 80% and 100% fractions showed different mechanisms (such as autophagy). The major compounds, which maybe were in charge of showing cytotoxic activity were non-terpenoids. Conclusion: This study provides the evidence that in vitro cytotoxic activity of n-Hexane extract and 80% and 100% VLC fractions of A. nemorosa inhibited the proliferation of breast cancer cells (MCF7) via a different mechanism.


Through analysising the seismicity data before M L ≥5.0 earthquakes in Ningxia and its adjacent areas since 1965,it is found that there mostly is the characteristics of enhancement of moderate earthquakes before M L ≥5.0 earthquakes.In A part of the study area,the probability for occurrence of M L ≥5.0 earthquake is 0.71 after anomaly of the enhancement of moderate earthquakes in 7 months;and it is 0.60 in 3 years in B part.The probability that earthquake locats near the outer linked lines of all earthquakes in one enhancement of moderate earthquakes is 0.79.Its R value is 0.75.So the enhancement of moderate earthquakes can be a middle period prediction method for M≥5 earthquake in this region.


We study the intersection of an algebraic variety with the maximal compact subgroup of a universal vectorial extension of a product of elliptic curves. For this intersection we show a Manin–Mumford-type statement. This answers some questions posed by Corvaja–Masser–Zannier, which arose in connection with their investigation of the intersection of an algebraic curve with the maximal compact subgroup of various algebraic groups. In particular they proved that these intersections are finite for universal vectorial extensions of elliptic curves. Using Khovanskii's zero-estimates combined with a stratification result of Gabrielov–Vorobjov and recent work of the authors, we obtain effective bounds for this intersection that only depend on the degree of the algebraic variety and the dimension of the group. As a corollary, we obtain new uniform results of Manin–Mumford type for additive extensions of certain abelian varieties.


Particle size, solids loading and impeller clearance from the base were all found to have significant effects on the just-suspension of fine particles in a stirred tank. At the higher end of particles size studied, where there is greater difference in settling velocities between particle sizes, the smaller the particles the less specific energy, εjs is required for just-suspension. But at the low end of particle size range, changes in the settling velocity are small while continued reduction in particle size corresponds to substantial increase in total particle surface area, leading to increased εjs possibly due to particles interactions. Just-suspension of PMMA particles of diameter 195.5 m required higher εjs than for 75.3 m particles, whereas εjs for 75.3 m particles was lower than that for 18.0 m diameter particles. Experiments were conducted in water in a 15.5 cm cylindrical tank at an aspect ratio of 1:1 over a range of loadings from 5 to 40% by weight. The HR100 and HS604 SUPERMIX® impellers manufactured by SATAKE, generally showed better efficiencies compared to the conventional 4 pitched-blade turbine and 3-blade propeller, in addition to being less affected by changes in operational parameters. The HS604 performance proved that a radial impeller can be comparable to or better than a downward axial impeller in solid–liquid suspension if used at very low clearance. S factor values under different experimental conditions are presented. © 2014 The Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.


When the electromagnetic field depth of penetration is much smaller than the other dimensions of the conducting domain, the numerical solution of the eddy currents problem can have a small accuracy. This disadvantage is even more important in the case of transient or periodical regimes. The analytical method of expanding the solution in a series of space eigenfunctions eliminates this disadvantage but can only be easily applied for sufficiently simple geometries of the analyzed domain. The method is used in this paper in order to compute the electromagnetic field for prefabricated beams heated through eddy currents. The specific losses are then calculated as well as the global losses and the voltage of the excitation coil. Several comparisons are made with numerical solutions obtained with the finite element method.


We study the asymptotic behaviour of solutions of Forward Backward Stochastic Differential Equations in the coupled case, when the diffusion coefficient of the forward equation is multiplicatively perturbed by a small parameter that converges to zero. Furthermore, we establish a Large Deviation Principle for the laws of the corresponding processes.


The parameters for a kilowatt-level high-power terahertz amplifier were explored based on the higher-order mode and extended-interaction mechanism. It has been demonstrated that the antisymmetric electrical field mode (TM21) has a unique advantage in achieving high power. Physical factors on power extraction were studied. In particular, the heavily reduced <inline-formula> <tex-math notation="LaTeX">${Q}_{{0}}$ </tex-math></inline-formula> has a great effect on the coupling characteristic as well as the output power. It is found that the critical coupling state, i.e., <inline-formula> <tex-math notation="LaTeX">${Q}_{e} = {Q}_{{0}}$ </tex-math></inline-formula>, defines an upper limit of the power that can be extracted from the output circuit. The design of a complete interaction circuit was accomplished. The particle-in-cell (PIC) simulations showed that a saturated power of 1.2 kW can be achieved at 220 GHz with a voltage of 45 kV and a total current of <inline-formula> <tex-math notation="LaTeX">$2\times0.6$ </tex-math></inline-formula> A where two beams were used. The saturated gain is over 30 dB with a 3-dB bandwidth of <inline-formula> <tex-math notation="LaTeX">$\sim 400$ </tex-math></inline-formula> MHz.


The purpose of this paper is to suggest the use of an interactive virtual electromechanical simulator in lieu of, or in conjunction with, an existing electric machine laboratory experience. Developed at the University of Arkansas, this software, possessing a friendly graphical user interface (GUI), is designed to be an effective pedagogical tool for the undergraduate and graduate curricula in the analysis and dynamic simulation of electric machinery. The program consists of two distinct parts: the controller and the electric machine modules. Both modules allow a wide range in modelling complexity since the user-supplied simulation code is written in the C++ programming language. All controller and electric machine variables can be monitored in real time-much like a strip-chart recorder. In order to demonstrate the features of this simulator, a virtual permanent-magnet brushless dc machine controlled by a six-step 180/spl deg/ continuous-current inverter is presented.


In Reply.—
 The analysis of our data by Mayes and Perrin is certainly appreciated. First, in answer to their inquiry about diagnosis, Schwartz diagnosed the otitis media in each case, using both pneumatic otoscopy and tympanometry. Though Schwartz' accuracy in diagnosis could be questioned, we feel that his diagnostic skills are at least as good as those of any other investigator who has reported on the management of otitis media.
 Second, as for the problem of changing denominators, we are grateful to Mayes and Perrin for pointing out the confusion between the table and the text.


Food-borne diseases such as salmonellosis are a major cause of human gastroenteritis worldwide, especially in the developing world due to poor sanitary conditions. Flies feed on food and breed in feces and other organic material. As such they are known vectors of Salmonella spp. Given that pork consumption in Uganda is rapidly increasing while good food safety practices remain absent, this study aims to assess the occurrence of Salmonella spp. in pork butcheries as a contribution to improve hygiene.

The purpose of the present research is studying the relationship between depression, anxiety and physical activity among young individuals who study at secondary schools. On voluntary basis, 226 male and 137 female; a total of 363 students between the ages 13-19 (average 15,44±1,25) participated in the research. The data related to physical activity variable were collected with "IPAQ Long Form – International Physical Activity Questionnaire; data related to Depression variable were collected with "Beck Depression Inventory", and data related to Anxiety variable were collected with "Beck Anxiety Inventory". Statistical analyses revealed that 63.3% of male students, and 75.1% of female students were not physically active or didn't have adequate physical activity levels; and physical activity level of male students were significantly higher than female students (Independent Sample T-test; p<0.05). There were no statistically significant differences across genders in terms of Anxiety and Depression scores (Independent Sample T-test; p<0.05), and physical activity classification (One Way ANOVA; p>0.05). Additionally, there were no statistically significant correlations between anxiety, depression and physical activity (Pearson Correlation; p>0.05). Consequently, we can claim that physical activity level is quite low among secondary school students. However, depression and anxiety aren't affected from physical activity level.


PURPOSE: To enable a contact area between a solder and a terminal to be always sufficiently assured when the solder is printed on a plurality of terminals formed on a board. CONSTITUTION: A mask 62 is used when the solder 64 is printed on the plurality of terminals 39 formed on the board 33 to correspond to the plurality of the terminals provided in an IC package. This mask 62 has an opening 63 for passing the solder 64, and the opening 63 is larger than the terminal 39. The wiring 38a adjacent to the terminal 39 might be covered with the solder 64, and when the solder 64 is reflow treated, the solder 64 is separated into a part 64a and the other part 64b to prevent the wiring 38a and the terminal 39 from being short circuited.


Various analogos of phosphonic acid, phosphinic acid, and CH3P(O) group containing organo-phosphorus compounds were synthesized as model compounds to investigate the effects of P content and the structure of flame retardant (FR) on their fire retarding performances of acrylonitrile–butadiene–styrene (ABS) and ethylene–vinyl acetate (EVA) copolymer. The success of synthesis was confirmed by 1H- and 31P-NMR. The flame retarding efficiencies were evaluated by a UL-94 vertical test method. Thermogravimetric analysis results reveal that all the mixtures of FRs with ABS or EVA exhibit no or very little charred residues at 600°C under inert atmosphere condition, indicating that all FRs work in the gas phase rather than in the condensed phase for both ABS and EVA. The fire retarding efficiency of FR depends not only on the P content in FR but also on the nature of its structure. UL-94 results show that P FRs with CH3 group attached to the P atom exhibits the best fire retarding performance on both ABS and EVA. It was found that at least 4 wt% P in the formulation is required to show self-extinguishing ability for both ABS and EVA when P FRs having CH3 group are employed. The fire retarding efficiency of P FRs with different attached group is in order of: CH3 > C6H5 > OH > H. Copyright © 2009 John Wiley & Sons, Ltd.


We introduce a technique based on data mining algorithms for classifying incoming messages, as a basis for an overall architecture for maintenance and management of e-mail messages. We exploit clustering techniques for grouping structured and unstructured information extracted from e-mail messages in an unsupervised way, and exploit the resulting algorithm in the process of folder creation (and maintenance) and e-mail redirection. Some initial experimental results show the effectiveness of the technique, both from an efficiency and a quality-of-results viewpoint.


To provide communication confidentiality in multicasting applications, traffic data in secure multicast is encrypted with a session key known only by certificated group members. Whenever there is a change in the group membership, the session key must be updated dynamically. Previous work has been focused on individual rekeying, there are two problems with individual rekeying: inefficiency and an out of sync problem between keys and data. This paper devises a batch rekeying scheme based on iterated hash function which can improve efficiency of the key server,and analyzes the key server's processing cost for batch rekeying.The simulation results show that our batch scheme,which is based on iterated hash function, compared to individual rekeying, saves server cost efficiently.


The invention discloses a system and method for treating domestic sewage in a rural area, which belongs to the technical field of environment-friendly sewage treatment. The domestic sewage enters an aerated grit chamber also serving as an adjusting tank for carrying out appropriate grit setting and adjusting, so that a part of inorganic pollutants is removed; the sewage is conveyed to a concentration type two-stage anaerobic reaction tank through a lifting water pump, suspended matters in the sewage are filtered and intercepted when the sewage passes through a concentration filter layer; contaminated gases, such as CH4, H2S and the like generated in the concentration type two-stage anaerobic reaction tank are discharged through a gas port; a part of concentration liquid is discharged out of the system through a concentration bottom sediment drainage pipe by opening a valve regularly; supernatant fluid from a water outlet of the concentration type two-stage anaerobic reaction tank enters a ladder plunge type wetland, a non-medium wetland, an economic income type wetland, a bacteria filter and a fishpond in turn; and nitrogen and phosphorus eutrophic pollutants in water are filtered, intercepted, adsorbed, decomposed, absorbed and precipitated by rootstocks of aquatic plants and the like. Therefore, according to the novel technology disclosed by the invention, the purpose of water purification can be achieved through regular harvest.

One of the major disadvantages of laminated composites is their tendency to delaminate. Unidirectional glass/epoxy laminates have been tested under static conditions by the use of fracture mechanics. Mode I, mode II, mixed mode I-II, mode III and mixed mode II-III tests were performed. Double cantilever beam (DCB), end-notched flexure (ENF), mixed-mode bending (MMB) and edge crack torsion (ECT) specimens were used. Scanning electron microscopy technique was used to identify distinguishing fractographic features and to establish the differences between the various modes of fracture after specimens testing. The propagated orientation of the delamination could be specified from the patterns of fracture surface. Scanning electron micrographs of fractured surfaces showed that the most predominant fractographic features in mode I and mode II are the large amount of fibre pull-out and the cusps markings respectively. In the MMB specimen the fracture surfaces are characterized by fibre breakage under shearing with fractures localized in the resin with cusps having an orientation of 90o (mode II) and also fractures localized in the resin and along the resin/fibre interface (mode I). Mode III characterization concluded that some limited mixed mode II-III seems to be present for ECT specimen on delamination initiation and growth, but a large majority of mode III delamination is present.


Under natural conditions,diurnal changes of photosynthetic and transpiration rate of six seabuckthorn cultivars and main environmental factors were measured by using LI-6400 photosynthesis system.The correlation coefficient,path coefficient and decision coefficient were used to determine the effects of main environmental factors on the diurnal changes of photosynthetic and transpiration rate of sea-buckthorn cultivars.The results were as follows:Diurnal change of photosynthetic rate of six sea-buckthorn cultivars showed bimodal pattern and an obvious midday depression at 13∶00o'clock.Diurnal change of transpiration rate of'Baiqiu'and'Shenqiuhong'both showed bimodal pattern,which of the others showed unimodal pattern.PARhad the greatest effect on the diurnal dynamics of photosynthetic and transpiration,and was the primary determining factor.Ca,Taand RH affected photosynthetic and transpiration mainly through their acting on PAR,and were the main limiting factors.


Background Improving sustained ROSC rates following out-of-hospital cardiac arrest is a key focus for ambulance services. Accordingly, a Quality Improvement (QI) project was initiated whereby an Intensive Care Society post-resuscitation care bundle of evidence-based interventions was adapted for use by pre-hospital clinicians. The objective was to introduce and embed this care bundle, in order to increase its delivery. Apr & May 2012 Apr & May 2013 Apr & May 2014 No. of patients 96 106 97 Complete Care Bundle 8.3% 32.1% 35.1% 12—Lead ECG 60% 71.7% 81.4% Blood Sugar 43% 94.3% 95.9% Cooling Started 49% 69.8% 62.9% Ventilatory Support 53% 52.8% 73.2% Haemodynamic Support 74% 82.1% 82.5% Method A baseline audit of care bundle compliance was conducted in April–May 2012 to act as a pilot bundle and provide a baseline. The final care bundle, comprising five key elements, was introduced during a QI event attended by 60 clinicians in April 2013. Since then, care bundle delivery has been regularly monitored. To sustain early gains, a Post-ROSC checklist was distributed to frontline vehicles, and a QI Collaborative discussed individual elements. A defibrillator 'aide memoire' sticker was developed, and will be trialled using a PDSA cycle. Results Care bundle delivery has progressed between the pilot period, and in the two subsequent years, demonstrating the success of the QI programme in embedding these interventions. Ventilatory support has received a particular focus, and the impact on provision is marked. In future, the care bundle will be updated to reflect the latest research evidence, including new guidance on cooling. SPC charts will monitor the impact of QI activities. Conclusion The care bundle model, alongside targeted QI activities, has proved successful in ensuring best-practice care is more routinely provided. These methods promote clinician co-production of practice development, and are adaptive to evolving clinical evidence.


ABSTRACT We report on an innovative computer-adaptive assessment, the Comprehensive Research-based Early Math Ability Test (CREMAT), using the case of 1st- and 2nd-graders' understanding of geometric measurement. CREMAT was developed with multiple aims in mind, including: (1) be administered with a reasonable number of items, (2) identify the level(s) of thinking at which the child is operating for each developmental progression (domain) of significant mathematics, and (3) provide information about specific concepts and skills that constitute the cognitive components of thinking involved in various tasks. CREMAT relies on Q-Matrix theory and a resulting blend of sophisticated psychometric and statistical techniques (Rule Space Method, poset models) to determine not only students' overall performance but also their specific level of thinking along developmental progressions. Results indicated that the current tests range from satisfactory to excellent in their ability to diagnose 1st- and 2nd-graders' understanding of measurement, but also suggest revisions and implications for the approach. We conclude with a description of why CREMAT is important for early childhood practitioners' ability to formatively assess and document children's progress in learning math.


BACKGROUND
Roux-en-Y gastric bypass (RYGBP) has had a posilive impact on co-mobidities associated with obesity. However, in the long-term it can induce micronutrient deficiencies.

AIM
To petform a complete nutritional assessment in a group of women previously operated of RYGBP from different socioeconomic levels (SEL).

PATIENTS AND METHODS
Thirtyy three women (19 high SEL and 14 low SEL), were assessed by dietary recalls, anthropometric measurements, muscle strength, bone mineral density, routine clinical laboratory, semm leeds of vitamin B12, 25OH-vitamin D, folate, calcium, ferritine ceruloplasmin and indicators of bone tutnoter (paratbohormone, osteocalcin and urinary pyridinolines). Their values were compared to those of 30 control women (18 high SEL and 12 low SEL).

RESULTS
Low SEL operated women consumed fewer vitamin and mineral supplements compared with their high SEL pairs. No cases of vitamin B12, folic acid or copper deficiencies were detected. Frequency of iron deficiency was similar in patients and controls. Vitamin D insufficiency was higher among patients than in controls (p = 0.047), regardless SEL. Patients had also a higher frequency of high senum P771 and osteocakin and urinary pyridinoline levels. However, no differences in bone mineral density were obseived between operated women and controls.

CONCLUSIONS
Vitamin and mineral deficiencies were lower than expected among operated women. However problems associated with vitamin D deficiency were highly prevalent among patients operated of RYGBP, irrespective SEL. These alterations were only detectable through specific markers at this stage, because they did not translate into lower bone mineral density (BMD) of sutgical patients, probably due to the higher pre-operative BMD of these moibid obese patients


The purpose of this paper is to see a smart energy evolution of the UK along with government projects and smart city project like "Smart London Plan (SLP)" in 2013 with the logic of business model innovation (BMI). For this, it discusses the theoretical logic and formulates a research framework of evolving smart energy from silo to integrated system. The starting point is the silo system with no connection and in second stage, the private investment in smart meters, smart grids implementation, energy and water nexus, adaptive smart grid systems, and building marketplaces with platform leadership. As results, the UK's smart energy sector has evolved smart meter device installation through smart grid to new business models such as water-energy nexus and microgrid service within on the smart energy city system.


To the Editor. —Two interesting cases of direct trauma to the superior oblique tendon following penetrating injuries of the upper eyelid were described by Bachynski and Flynn1in the October 1985Archives. In the first case, Bachynski and Flynn described severe damage to the superior oblique muscle necessitating superior oblique tendectomy. The superior rectus muscle was recessed during the same procedure. It appears to me that a more appropriate procedure would have been an inferior oblique myomectomy or recession, weakening the direct antagonist of the superior oblique. Why did Bachynski and Flynn choose to weaken the superior rectus muscle?


This paper uses a multi-method approach to measuring the concept of "textual review dimensionality" based on the topic dispersion of textual reviews, empirically examining how textual review dimensionality dynamically influences the perceived helpfulness of online reviews. Building on prior work, we create a novel supervised topic modeling approach, a prior-topic-words (PTW) -guided LDA, to extract pre-defined topics and their level of presence from a large size corpus of textual reviews. Based on this method, we propose a topic dispersion measure to measure textual review dimensionality based on information entropy. We use large-scale secondary review data obtained from TripAdvisor and a randomized experiment to examine the dynamic effect of textual review dimensionality on review helpfulness. We find that balanced textual reviews are initially perceived to be more helpful than focused ones, but this effect is attenuated when a balanced review is read later in a sequence of reviews. We elaborate on the important theoretical and methodological implications of our research, specifically discussing takeaways for managers looking to design a more informative online review platform.


We have measured the fracture strength of multi-crystalline silicon (mc-Si) wafers to investigate the possible effect of laser hole drilling on the breakage rate of metal wrap-through (MWT) solar cells. Groups of solar wafers with 0, 100, and 300 holes (130 μm diameter) were prepared using a UV Q-switched laser. For each group, half of the wafers were subjected to a wet chemical etch (standard HF–HNO3 texture etch). The breakage force was measured with a plate-twist test apparatus. For the unetched wafers, a strong correlation could be found between the number of laser-drilled holes and the breakage force. For the etched wafers, however, no statistically significant difference could be found between the different groups. Our results indicate that the microcracks created by our UV laser-drilling process can be successfully treated with the standard texture etch, in contrast to the previous studies using IR and green lasers.


ANSYS/LS-DYNA is used to simulate the penetration process of B900FD-1 bulletproof armor plate,Comparisons and analysis were made between numerical simulation and experiment results.The numerical simulations shows that the Johnson-Cook constitutive model could simulate the physical and mechanical behaviors of ductile materials under shock-loaded.The ultimate-thickness of B900FD-1 bulletproof armor plate under 500m/s impact velocity is analyzed by more numerical simulations.


Protease inhibitors including indinavir have gained widespread use in the management of HIVinfected patients. Although nephrolithiasis and asymptomatic bilirubinaemia occur commonly in association with indinavir, acute hepatitis is not a well recognized adverse effect of indinavir. We report a case of indinavir-associated severe acute hepatitis in a patient with AIDS. To our knowledge, only 3 cases of this serious adverse effect have been reported previously1. A 46-year-old man with CD4 count of 10 cells/ml had been on treatment with trimethoprim-sulfamethoxazole, zidovudine, didanosine, and desimipramine for 7 months prior to the addition of indinavir (800 mg, thrice a day). Serology for hepatitis B and C virus was negative. Liver function tests 3 weeks after the institution of indinavir were normal. Forty-six days after treatment with indinavir, the patient presented with mid-epigastric pain and nausea of one week's duration. On examination, right upper quadrant tenderness and hepatomegaly were documented. Total bilirubin was 3.7 mg/dl, alanine aminotransferase was 123 IU/l, gamma glutamyl transpeptidase was 520 IU/l and the alkaline phosphatase was 136 IU/l. An ultrasound and CT scan of the abdomen revealed hepatomegaly with no evidence of duct dilatation. All medications were discontinued. An endoscopic retrograde cholangiopancreatogram (ERCP) was unremarkable. A liver biopsy (performed via transjugular approach) revealed steatosis, eosinophilic degeneration, and ® brosis; these ® ndings were similar to a previous biopsy proven case of indinavir hepatitis1. Over the ensuing several days, the patient developed massive ascites and anasarca requiring diuretics. His serum bilirubin peaked at 12.2 mg/dl before gradually returning to normal. Our patient developed acute onset hepatitis with severe hepatocellular injury, hypoprothrombinaemia, ascites, and anasarca that was temporally related to the initiation of indinavir. There was no evidence of viral or alcoholic hepatitis on liver biopsy and extensive workup including ERCP failed to reveal an alternative aetiology of his acute hepatitis. At the time when this case was encountered, the only reported adverse effect of indinavir associated with jaundice was asymptomatic indirect hyperbilirubinaemia documented in up to 10% of the patients2,3; discontinuation of indinavir is not recommended in such patients. Our patient, as in the 3 previous cases, had advanced AIDS as indicated by CD4 counts of less than 50/ml. Thus, indinavir-associated hepatitis should be a consideration in patients with advanced HIV infection who develop acute hyperbilirubinaemia in conjunction with abnormal transaminases upon institution of indinavir. Indinavir treatment should be promptly withheld in such patients.


Based on the annual data released by We are Social 2020, shows that Indonesia is a country with the highest rate of e-commerce adoption in the world, but is lagging behind in using mobile payments (m-payment). However, it is common to find that m-payment integrated with e-commerce. Why does it happen? To find this out, we conducted this research. The Technology Acceptance Model (TAM) used to parse the decision to use the m-payment technology. Then added financial literacy as antecedent for decision using mpayment. Data collected using questionnaires distributed to students and collected 120 respondents, then analyzed by using SEM. The result showed that the perception of easy to use is not a consideration in using m-payment but rather the perception of usefulness and security. The financial literacy does not influence the intention to use m-payment, but it has an impact on the behavior of using mpayment.


Significance: Biaryl atropisomers are common structural units, found in various biologically active compounds, and they are excellent ligands in asymmetric catalysis. Because of their widespread applications in pharmaceuticals and asymmetric synthesis, the selective construction of these biaryls with a high substituent diversity is very useful. The synthetic utility of the present copper-catalyzed thiolative ring-opening reaction was demonstrated by the synthesis of an axially chiral P,S-ligand. Comment: Gu and co-workers have developed a copper-catalyzed enantioselective synthesis of atropisomeric 2′-iodo[1,1′-biphenyl]-2-yl thioates by the thiolative ring-opening reaction of fivemembered cyclic diaryliodonium compounds with potassium thioates in the presence of a (phenyl)bis(oxazoline) ligand. The axially chiral biaryl products were isolated in high yields and with high enantioselectivities. I Selected examples: Cu(MeCN)4PF6 (5.0 mol%) ligand (7.5 mol%) CH2Cl2, –20 °C


It has been demonstrated that the construction industry can be characterized by inefficient and ineffective service delivery. The main goal of this paper is to examine the critical causal factors affecting public infrastructures projects performance in Ethiopia in order to improve the industry's service delivery. Based on the 58 factors compiled through the analysis of existing theories and investigations, we prepared and distributed 700 structured survey questionnaires for professionals in the construction industry of Ethiopia; and received 578 (82.57 %) of them. The results from an extended statistical analysis on the collected data revealed that the top 8 critical specific factors affecting government-financed infrastructures projects performance in the Ethiopia comprehends: poor project planning & administration system, weak project management leadership skills & institutional capacity, inadequate project design, escalation of construction materials price, lack of integrated project planning system among parties, inadequate capacity of the contractor, poor project schedule and cost management system. The study has an implication for construction industry practitioners, government officials, and research fellows. Introduction Through promoting infrastructures investments, create job opportunities, and deeds as a major consumer of intermediate products, and related services from another business sector via its complex value chain; Construction Industry acts as an engine for socio-economic development of a nation[1, 2] [3-5]. However, the sector is troubled with numerous internal and external factors that hamper the productivity of the industry across the world. The critical of them include: its complex nature, ever regulation change ,unreliable contractor, high insurance cost, technology adoption limitation, management aspect, market price change, inadequate capacity both in finance and technique, labor shortages, stagnant productivity level and failing to delivery project as the intended time, cost and quality standards are belongs to the most constraints of this sector [6]. Consequently, nowadays, a construction project is characterized by inefficient and ineffective project delivery globally[7-11]. Due to the presence of varied underlying problems which affect industry productivity, the sector is characterized by underperformance [12-13]. Previous studies clarified diverse factors affecting the performance of the construction industry. Though, due to the rapid changes in everything in this world, there is still a wide gap to thoroughly understand the underlying problems caused by the underperformance of this sector [5, 14]. Ethiopia has no exception regarding problems associated with the construction industry performance. As the case in Ethiopia, conflict among project participants, the project manager's ignorance and lack of knowledge and poor human resource management are the top factors hindering the schedule performance of public projects[15]. It is also suggested that due to less emphasis to planning, failure to update schedule on time, poor contract management, poor site supervision, inflation price of construction materials, change order, delayed payments, schedule overrun, quality defect cost overrun, capacity problems, weak organization, and coordination failing public infrastructures projects execution in Ethiopia suffer from performance failure[16, 17].

As H5N1 avian influenza virus can infect mammalian,research of vaccine against H5N1 virus became urgent.Our study aimed to examine the infectious status of recent H5N1 viruses against Balb/c mice and select a highly pathogenic H5N1 virus. We inoculated mice were intranasally with 17 strains H5N1 viruses isolated from poultry in southern China.The virulence and lethality were observed,while TCID_(50),EID_(50),mice LD_(50),and virus loading were measured;the phylogenetic tree was drawn through HA sequence analysis.Among the 17 H5N1 strains,1 was highly lethal to mice(TCID_(50)/100μl=7.2,EID_(50)/100μl=8.325,LD_(50)/100μl= 6.318≈10~2EID_(50)).Avian influenza virus NS segments were detected from lung,spleen,nose,and brain tissues of infected mice.The viral load in brain tissue was the highest,which was up to 3.56×10~(10) copies/5μl.These results indicate that most of H5N1 viruses from poultry are nonpathogenic for mice;this mouse model can be used to evaluate the cross-protection of avian influenza vaccine and also to investigate the prophylaxis and treatment of H5N1 avian influenza viruses.


Letter from Gus C. Garcia to Jack Ross, Board of Pardons and Paroles, Austin, Texas. Garcia expresses disappointment over the case of Pete Hernandez and that Hernandez is still confined in prison. Garcia wishes to meet Jack Ross in person to discuss this matter, because Garcia feels that Hernandez's case was a question of jury discrimination.


A B S T R A C T In this work we report the variation in the CAC (critical aggregation concentration) and CMC (critical micelle concentration) of Brij56+CTAB mixture with change in non-ionic semi-flexible polymer, hydroxypropylcellulose (HPC) using tensiometry,in aqueous medium. The tensiometric profiles of Brij56+CTAB mixture in the presence of HPC exhibit two breaks, one is at critical aggregation concentration (CAC) corresponding to onset of interaction of Brij56+CTAB with HPC and the second at C1 corresponding to saturation of the polymere. The Brij56+CTAB show similar tensiometric profiles as shown by the individual surfactants with the same poymer. The CMC of Brij56+CTAB shows generally first increase with increase in polymer concentration and then shows decrease with further increase in polymer concentration. The change in the interactions of mixed micelles with polymers can be used to modify the properties of solutions for various industrial uses. Keywords-Brij56, CTAB, CAC, CMC,


One interpretation of the record breaking New South Wales election last Saturday is that the electorate didn't just speak; it roared. Another – based on anecdotal evidence of a lack of visible anger at polling booths – is that the execution instead came with a quiet sense of calm resolution. It might be that voters were angry months or even years ago, and it was then the gallows were assembled. By the time 26 March, 2011, had rolled around, prayers had been said and final absolution granted. All that was left was for voters to give a collective pull on the lever, and to let the corpse of NSW Labor swing gently in the breeze, perhaps as a warning to others.

Hierarchical structure design and use of cocatalyst are effective strategies to improve the photocatalytic performance of semiconductor catalysts. Herein, 0D NiSe2 nanoparticles decorated 2D ZnIn2S4 ultrathin nanosheet‐assembled microflowers using a facile solvothermal approach are synthesized. The as‐obtained NiSe2/ZnIn2S4 nanocomposites exhibit enhanced visible‐light photocatalytic H2‐evolution activity of 1487 µmol (g h)–1, three times higher than that of pure ZnIn2S4. The hierarchical structure of ZnIn2S4 microflowers exposes more surface‐active sites and enhances light harvesting. Meanwhile, the formation of heterojunctions between ZnIn2S4 nanosheets and NiSe2 nanoparticles creates a space‐charge separation region that facilitates the transfer and separation of photoinduced electrons and holes, resulting in improved photocatalytic H2 production. This work provides a promising strategy for designing and constructing 0D/2D heterojunctions for efficient solar‐driven energy conversion.


The case of Pape v Commissioner of Taxation is discussed to see how the case might apply one hypothetical instance by examining its potential impact should a challenge be made to Commonwealth spending on housing.

This Analysis of ECG signals is crucial for early detection of cardiac ailments. With the sensors becoming more and more predominant and available in all wearable forms for measuring multiple physiological parameters, the importance of algorithms to detect the abnormalities are also gaining importance. The physiological signals are measured through noninvasive means unless very critical and hence are very weak in nature. Bio-amplifiers are applied during signal acquisition. The signals are weak and hence susceptible for the electrical disturbances in the environment. Selection of Filtering techniques is very important and is decided by many factors. This paper is a survey which presents digital filtering techniques the researchers have applied in the last decade. The study reveals the different types FIR/IIR filters the researchers have worked and also the performance metrics adapted by the researchers electronic document is a "live" template and already.

The integrated information lies within regions over which the maximal peaks of the overlap function occur with the largest spread. The original proposal for generating and analyzing the overlap function is centralized and can only take place at the processing center. A distributed integration of the overlap function is proposed in [29] for the mobileagent-based computing such that at each stop of the itinerary, a partially integrated result can be generated from previously migrated sensor node outputs and the accuracy of the information derived from this result can be used to justify if the mobile agent needs to continue with its migration. The distributed method would generate the same output as the centralized method if the mobile agents finishes its itinerary.


Friday, July 13, 2012, marked the passing of Joseph Michael Foley, Past President of both the American Academy of Neurology (1964–1966) and the American Neurological Association (1975–1976), and a leading figure in the development of neurology in the last half of the 20th century. Born in Boston on March 9, 1916, to immigrant Irish parents, he was educated at the Boston Latin School, Holy Cross College, and Harvard Medical School (HMS), from which he graduated in 1941. Coming from a poor family (his father was a garbage collector), and educated in the midst of the Great Depression, his education was entirely paid by scholarships. The HMS scholarships stipulated that he do research in addition to his coursework, which led to his first publication ("The vascular supply of the hypothalamus in man"), and sparked his academic interests.


Transient characteristics of power system has developed significantly because of the increasing share of renewable energy generations (REGs). In order to cope with these inevitable impacts from large scale REGs. This paper presents a practical small resistance earthing protection computation for REGs relay protection configuration scheme under extreme fault conditions. First, relay setting calculation is analyzed to identify its key characteristics in renewable energy generation dominated power system. Second, we propose an improvement small resistance earthing protection computation strategy based on theoretical analysis above. Considering the difficulties in project implementation, the detailed calculation process is given with practical engineering example and operation data verify the proposed method.


among these elements. What, precisely, Seymour means by this distinction is rendered considerably less clear when he takes as an example of homogenization the Party's recent attempt to involve younger members in leadership roles through "three-in-one" combinations of young, middle-aged, and old. While individuals of different ages may usefully be conceived of as being integrated within a political system, it is not clear how the problem of age differences can be seen as soluble by "homogenization," as Seymour has defined that term. Moreover, the book's emphasis on "subintegration" dates it somewhat, since that policy appears to be much less central to the economic and political planning of Mao's successors than it was to that of Mao himself.


Spatiotemporal characterization of μJ-class ultrashort THz pulses generated from a laser plasma accelerator (LPA) is presented. Accelerated electrons [1], resulting from the interaction of a high-intensity laser pulse with a plasma, emit high-intensity THz pulses as coherent transition radiation [2]. Such high peak-power THz pulses, suitable for high-field (MV/cm) pump-probe experiments [3], also provide a non-invasive bunch-length diagnostic [4] and thus feedback for the accelerator. The characterization of the THz pulses includes energy measurement using a Golay cell, 2D sign-resolved electro-optic measurement and single-shot spatiotemporal electric-field distribution retrieval using a new technique, termed temporal electric-field cross-correlation (TEX). All three techniques corroborate THz pulses of ∼ 5 μJ, with peak fields of 100's of kV/cm and ∼ 0.4 ps rms duration. Single-shot measurement of the THz spatiotemporal waveform demonstrates a dependence of the THz spectrum on the electron bunch properties and dynamics in the LPA.

Introduction It is established that Interleukin-1 (IL-1) is expressed by native nucleus pulposus (NP) cells and that disregulated expression is associated with the pathogenesis of IVD degeneration1. IL-1 has been shown to regulate diverse cellular functions within the IVD including those related to catabolic and anabolic activities2. Here the regulatory potential of IL-1 on chemokines that we have previously identified within the human IVD is investigated to address the hypothesis that regulatory interrelationships exist between cytokines and chemokines in the IVD. Materials and Methods Primary human NP cells cultured in alginate beads were subjected to 48 hours treatment with IL-1. RNA extracted from these cultures was used in qRT-PCR gene expression analysis to determine the effects of treatment on the expression of selected target chemokine genes. Cell culture supernatants from these cultures were used to determine the effects of treatment on protein production of selected chemokines. Results Constitutive expression of CXCL8, CCL2, and CCL7 was observed in alginate bead cultured primary human NP cells. Following 48 hours IL-1 treatment expression of CXCL8 and CCL2 was upregulated (Fig. 1A). Constitutive expression of IL-1 and CCL3 was not observed in alginate cultured primary human NP cells however, expression was induced following 48 hours IL-1 treatment (Fig. 1B). Conclusion This study demonstrates the regulatory potential of IL-1 in relation to a number of chemokines some of which have not been shown previously and adds to the body of evidence implicating IL-1 as a key regulator of NP cell biology.

Supplementary exercises in Junior middle school Chinese book published by People's Education Publishing House can be divided into accumulating exercises,comprehension exercises and application exercises,with the largest proportion of application exercises.The evaluation,as content options,is flexible and opening,guided to supplementary reading,connected with life experiences,and integrated by listening,speaking,reading and writing,but also has the orientation of neglecting tool characteristics.From the organization and presentation of content,it follows the law for students to understand,respects students' special feelings,focuses on students' imagination,and emphasize comprehensive ability,but it has apparent lack of internal logic modules.


The so-called "elite theory", of which Robert Michels was one of the canonical authors, is a body of doctrine which aims to demonstrate the impossibility of a more democratic and egalitarian social order. It is thus an example of the "futility thesis" discussed by Albert Hirschman, which states that any attempt to change the world is useless. The article argues that, despite this, the "iron law of oligarchy" presented by Michels in 1911 may be appropriate for a reflection committed to the advancement of democracy. Instead of leading to the abandonment of the democratic ideal, it serves as a warning against bastardization of that ideal by the very institutions who claim to implement it, providing tools for a critical analysis of political representation.


Existing literature demonstrates that gratefulness is a critical determinant for individuals' well-being and their quality of interpersonal relationships. A sense of gratefulness provides a perspective in which individuals could have a positive evaluation in life, including the way they view challenges. Positive appreciation of life's challenges would allow individuals to increase their coping ability and would motivate them to do prosocial behavior. This study aims to determine the role of prosocial behavior and social support to individuals' sense of gratefulness. Participants in this study consisted of 250 participants aged between 13–55 years old. The instruments used in this research were Gratitude Questionnaire, Philosophies of Human Nature Altruism Scale, and Social Support Scale. Multiple regression analysis was used to analyze the data. The result revealed a strong contribution between prosocial behavior and social support toward gratitude. Gratitude and prosocial behavior contribute in enabling individuals to have a positive evaluation oflife.

There are different types of shrimp found in different habitat characters.


This paper presents a novel method for the study of lager fossil unit thermodynamic systems, which is referred to as the fluid grid method. This method analyses thermodynamic systems by means of the mature electrical network theory, and uses a fluid grid as an analogy of a thermodynamic system. It defines firstly the matrix representation of gird and proves that the Rank of simple graph conjunction matrix is a v-1 conjunction matrix and obtains the conjunction matrix of a directed graph of a thermodynamic system fluid grid by analyzing the fluid grid of a thermodynamic system. And then it derives the mass and energy balance equations by means of the directed graph of a thermodynamic system and further derives the characteristic matrix equation for the fluid grid method by integrating the mass and energy equations. Finally it proposes an implementation scheme of the fluid grid method based on the characteristic matrix equation. An experimental study on a real-time example verifies the validity of this proposed method.


One of the knotty problems in face recognition is that the accuracy drops a lot in the case of recognizing faces captured in varieties of poses. In this paper, a patch-wise normalization method for non-frontal face images is proposed which is practical, effective, and can work well in continuous poses. Firstly, the correlation between 3D face model and the input 2D face image is constructed by the five facial landmarks detected from the input image. And then, a grid of key-points which are manually labelled on the 3D model are mapped onto the probe face image. Finally, for a pair of patches located at the positions which have the same semantic meaning in face images, a warp is estimated by calculating the homography matrix. The reconstructed frontal face image is obtained by stitching all patches sequentially. Recognition experiments on the FERET database proves that the proposed method is effective.

Machine-to-machine (M2M) communication represents a new paradigm for mobile cellular networks, where a massive number of low-cost devices request the transfer of small amounts of data without human intervention. One option to tackle this problem is obtained by combining random beamforming (RBF) with opportunistic scheduling. RBF can be used to induce larger channel fluctuations, and opportunistic scheduling can be used to select M2M devices when their overall channel quality is good. Traditional RBF does not fulfill M2M requirements, because overall channel quality needs to be tracked continuously. In order to tackle this limitation, a novel codebook-based RBF architecture that identifies in advance the time instants in which overall channel quality should be reported, within a coherence time window, is proposed. This opportunistic feedback mechanism reduces signaling overhead and enables energy saving at M2M devices. A simplified methodology is presented to evaluate the system mean data rate, using for this purpose closed form formulas derived from SNR distribution approximations. Results reveal that the performance loss that is experienced for introducing the proposed modifications to traditional RBF scheme is negligible. The concepts analyzed in this paper provide useful insights, and show that codebook-based RBF with simplified opportunistic scheduling algorithms is an excellent combination to provide wide-area M2M services with low-cost devices and limited signaling overhead.


A detailed N/H reaction mechanism has been developed and validated in comparison with experimental data for ammonia pyrolysis in shock waves (Davidson et al., Int. J. Chem. Kinet, 1990, 22:513). It has been shown that incorporation of the reactions with N2H3 and N2H4 into the mechanism significantly influences calculated rise-time and peak concentrations of the NH and NH2 radicals if the currently adopted rate constant of the reaction is employed. A sensitivity analysis reveals which reactions are critical for the quality of the modeling in particular experimental conditions. The choice of the rate constants for these reactions is discussed. It has been found that only significant decrease of the reaction (22) rate constant can improve the agreement between the modeling and experimental data. The best fit in the range 2200 - 2800 K is met with the rate constant k22 = 1.0E+11 T0.5 exp(-21600/RT).


While distinct terms, body and technology will always necessitate their interdependent consideration as a relationship. Likewise it becomes increasingly difficult to talk about bodies and technologies as separate entities 13 and therefore similarly to separate theories of technology from theories of our embodiment.

Body image (BI) is considered as central to many aspects of human functioning including emotions, thoughts, behaviors and relationships. This study aimed to investigate the prevalence and the main determinants of distortion and dissatisfaction among teenagers.

 This was a cross-sectional school-based study using a self-administered questionnaire, conducted among a randomized sample of 1300 school-adolescents in Southern Tunisia, 2018. BI perception was assessed by the Stunkard Figure Rating Scale.

 Among 1210 respondents (93%), BI distortion and dissatisfaction prevalence were 44.8% and 42.4%, respectively. Multivariate analysis showed that 16-18 years age group (Adjusted Odds Ratio (AOR)=1.28; p = 0.046), low family financial situation (AOR=1.88; p = 0.014), as well as high frequency of eating pasta (AOR=1.3;p=0.04) and fast-food consumption (AOR=1.7;p=0.042) were independently associated with under-estimated BI. Skipping breakfast (AOR=1.9; p = 0.017) and having one obese parent (AOR=1.9;p=0.01) were independently associated with higher frequency of over-estimated BI. For BI dissatisfaction, independent factors associated with desire to lose weight were female gender (AOR=1.53; p = 0.007), high family financial situation (AOR= 2.1,p=0.008) and having one parent obese (AOR=2.21,p<0.001). Frequent fast-food consumption (AOR=1.9, p = 0.038) and eating between meals (AOR=1.57,p=0.01) were associated with higher desire to gain weight.

 Our study highlighted a substantially high prevalence of BI distortion and dissatisfaction among adolescents. Their determinants included socio-demographic factors and lifestyle behaviors. Increased awareness among parents and public health planners may help adolescents improve accuracy of BI attitudes.

 BI distortion and dissatisfaction are pervasive problems that increased negative affect in adolescents. Promotion of healthy lifestyle including balanced diet and physical activity is warranted.


Results from the production and decay properties of element 115 nuclei observed using the reaction ${}^{243}\mathrm{Am}+{}^{48}\mathrm{Ca}$ at various beam energies between November 1, 2010, and February 26, 2012, at the Dubna Gas Filled Recoil Separator are presented. This long-running experiment with a total beam dose of $3.3\ifmmode\times\else\texttimes\fi{}{10}^{19}$ and carried out in the excitation energy range ${E}^{*}=31$--47 MeV of the ${}^{291}$115 compound nucleus resulted in observation of three isotopes of element 115 with masses 287, 288, and 289. The 28 detected decay chains of ${}^{288}$115 show that this isotope is produced with the maximum probability at ${E}^{*}=34.0$--38.3 MeV with a corresponding cross section of ${\ensuremath{\sigma}}_{3n}=8.{5}_{\ensuremath{-}3.7}^{+6.4}$ pb. The four events attributed to the isotope ${}^{289}$115 that decays via a short $\ensuremath{\alpha}\ensuremath{\rightarrow}\ensuremath{\alpha}\ensuremath{\rightarrow}\text{SF}$ chain could be detected only at the lowest excitation energy ${E}^{*}=31$--36 MeV, in accordance with what could be expected for the 2$n$-evaporation channel of the reaction. The decay characteristics of this nuclide were established earlier (2010) and more recently (2012) in the reaction ${}^{249}$Bk(${}^{48}$Ca,4$n$)${}^{293}$117 and following $\ensuremath{\alpha}$ decay to ${}^{289}$115. At the energy ${E}^{*}=44.8\ifmmode\pm\else\textpm\fi{}2.3$ MeV we observed only a single long chain of the isotope ${}^{287}$115. The decay properties of nuclei starting at ${}^{288}$115 and ${}^{287}$115 isotopes obtained in the present work reproduce in full the results of the first experiment of 2003 that reported the discovery of elements 115 and 113. The excitation functions of the production of the isotopes of element 115 and observation of the isotope ${}^{289}$115 in cross-bombardment reactions with the targets of ${}^{243}$Am and ${}^{249}$Bk provide additional evidence of the identification of the nuclei of elements 115 and 113. The experiments were carried out using the ${}^{48}$Ca beam of the U400 cyclotron of the Flerov Laboratory of Nuclear Reactions, JINR.


Classical planning approaches of storage allocation decisions are often conducted iteratively with significant manual effort. Warehouse layouts are generated on the basis of planners' experiences with the target to reduce the operators' travel distances and thereby to increase productivity. By combining optimization and simulation in a software-based planning tool, a multitude of mathematically optimized storage allocation scenarios can be generated and analyzed to improve traditional planning approaches. This paper describes a practical case of a German automotive manufacturer's warehouse allocation problem that is approached using an evolutionary meta-heuristic. The best solutions of the optimization are loaded into a large scale, automatically generated simulation model and evaluated using the company's real-life data.


Introduction: Pedicle fixation has become a common surgical practice now-a-days. Proper understanding of the anatomy of the vertebral pedicles is a prerequisite for the spinal surgeons. Knowledge of pedicle morphometry would reduce the risk of post operative complications. Aaccurate placement of well-fitted pedicle screw and non-interference with the adjoining neural structures is the key of successful surgery. Methods: Various parameters viz. length, breath, height, transverse angle and sagittal angle of the pedicle along with interpeduncular distance were measured in computerized tomography scan in all the 64 study subjects. Observations & Results: Male subjects showed higher length, breath, height, transverse angle, sagittal angle and interpeduncular distance for all vertebral segments than their female counterpart. Steady raise in the measurements have been observed in length, breath and height of both the sexes from D9 to D12 vertebrae. Same parameters showed a gradual raise following a dip from D12 to L1 vertebrae. Wider transverse angles have been noted at D9 level. Transverse angles at D10 were narrowest, with progressive widening caudally. Sagittal angles became marginally more caudal wards from D10. No obvious left right asymmetry has been recorded. Interpeduncular distance in both the sexes showed gradual raise from D9 to D12 vertebrae. With a dip at L1 from D12, a steady increase of the interpeduncular distance has been recorded in successive lumbar vertebrae. Conclusion: Outcome of the present study showed notable transition at thoraco-lumber junction. Detailed morphometric data generated from this study would be of immense help as a guide for pedicular surgery.


Two winter wheat (Triticum aestivum L.) cultivars, Fredrick and Norstar, which differ in their winterhardiness potential, were compared with regard to the effects of nitrogen (N), phosphorus (P) and potassium (K) application, during acclimation, on the expression of four traits associated with winterhardiness — freezing, ice-encasement, and low temperature flooding tolerances and crown moisture content. Modified Hoagland's nutrient solutions containing five levels of each nutrient were applied to the seedlings during a 5-wk acclimation period at 2 °C, and subsequently the crowns were tested for their ability to survive varying intensities of the stress treatments. Increasing the level of applied N from 0, caused a reduction in the level of all stress tolerances. Increased P did not significantly alter the expression of freezing tolerance, but tended to increase tolerance of the anaerobic stresses, icing and low temperature flooding, to an optimum. Increased K had minimal effects on stress tolerance at the...


Afghanistan has been the hotbed of the international conflict since the Soviet invasion in December 1979. The decade long foreign troop presence mainly initiated the conflict within the different communities in Afghanistan. the withdrawal of the Soviets in no way marked the end of the Afghan conflict. With the Soviet withdrawal gave rise to a power vacuum and then the Taliban. The withdrawal of the Soviets intensified the intra-state conflict in Afghanistan and also the involvement of the external actors. The involvement of the external actors further intensified the intra-state conflict and the same continued till 1996. Afghanistan witnessed a kind of a stability for a brief period with the rise of the Taliban. The Soviet invasion and the civil war had already given rise to multiple militias and they continuously engaged the Taliban government/forces, and Afghanistan never saw the peace. The Taliban government too was not elected, so the challenges were bound to rise. The conflict continued till 2001. After the 9/11 terrorist attacks on the US, the conflict in Afghanistan took a new turn. US intervened in Afghanistan to dislodge the Taliban government and started the war on terror. Again, number of international actors fiercely got involved in Afghanistan. The United Nations, the NATO, Pakistan, Iran, India, Turkey, etc. all are now involved in the race for dominating Afghanistan, which further intensified the conflict in Afghanistan.


In the field of domestic refrigeration, it is important to look for methods that can be used to simulate, and, thus, improve the thermal behavior of the fresh food compartment. In this sense, this study proposes some methods to model the thermal behavior of this compartment when the shelves' positions are changed. Temperature measurements at specific locations in this compartment were obtained. Several shelf position combinations were performed to use three 2D interpolation methods in order to simulate the temperature mean and the temperature variance. The methods used were: Lagrange's interpolation, cubic spline interpolation and bilinear interpolation. Two validation points were chosen to verify the proposed methods. By comparing the experimental results with the computer simulations, it was possible to conclude that the method of Lagrange's interpolation provided values that were not close to the real measured values. On the other hand, it was observed that the method of bilinear interpolation offered the best results, estimating values which were very close to the actual experimental measurements. These interpolation methods were used to build color thermal graphs that can be used to find some of the most appropriate shelf position combinations in this type of refrigerator. By inspection of these thermal graphs, it can be seen that the lowest average temperature was obtained when one shelf was located at 24.5 cm while the second shelf was located at 29.5 cm measured from the top of the compartment. In the same way, it can be seen that the minimum temperature variance was obtained when only one shelf was inside the compartment and this shelf was located at 29.5 cm.


The precipitation characteristics of sulfate ion and chloride ion in different mortars with slag and fly ash were investigated by testing amount of corresponding ions precipitating in different positions of mortars under simulation natural diffusion condition.Results indicate that the precipitation amount of sulfate ion and chloride ion in mortar are influenced remarkably by addition of fly ash and slag.Combination of fly ash and slag can decrease greatly the amount of ion precipitating in surface layer zone of mortar.The variation of precipitation amount of sulfate ion in mortar with increasing immersing ages differs from that of chloride ion precipitating in mortar.The increasing rate of amount of chloride ion precipitating in surface layer zone of mortar is larger than that of sulfate ion.This achievement will provide some important scientific basis for improving the resistance of cement-based materials to salt attack.


NN inelasticities are determined from a helicity partial-wave decomposition of a peripheral model for NN..-->..NN..pi... The helicity partial-wave formalism is presented for the reaction NN..-->..NN..pi.. and the relation between partial-wave helicity amplitudes and NN partial-wave reaction cross sections is derived. Partial-wave cross sections are projected out of the pion- and rho-exchange diagrams with NN and N..delta.. intermediate states. Below 1000 MeV one obtains significant contributions to the total cross section from many isospin one partial waves while isospin zero inelasticities are non-negligible only for J = 1. Large /sup 1/D/sub 2/ and /sup 3/F/sub 3/ inelasticities originate in these first-order Born-approximation terms for NN..-->..NN..pi.. which have no resonance behavior in the NN system. The effects of omitting rho exchange and form factors from the model are studied and determined to be small for L> or approx. =3. Comparisons are made with other calculations of NN inelasticities and show qualitative agreement.


Background SARS CoV2 pandemic has generated interest in research of virus spread sources, apart from human contagion. In particular different studies are performed to understand surfaces involvement;during the epidemic event, different types of studies on surfaces have been performed. However, there is little information regarding the presence of the virus in food;wastewater contamination and poor hygiene practices could be the sources of viral contamination in handled food products. The aim of this work was to analyze different types of food for Sars CoV 2 presence. Methods 390 samples of molluscs, 353 vegetables, 10 meat, 72 water, 169 berries, 16 seafood products and ready-to-eat dishes were analysed (2020-2021). Samples were selected from those provided for routine analysis during the pandemic period. The preparation was done based on ISO 15216-2 indications, followed by extraction with Nuclisense®Minimag® system;real-time PCR was applied to detect the Sars CoV2 virus Open Reading Frame 1ab, with two different master mixes. Results All samples tested were negative for ORF1ab detection. Many hypothesis can be made about negative Results: it could be possible that contamination levels in water, or on surfaces in contact with food, are too low to generate a detection signal;again, handling practices may be sufficient to avoid the transmission of the virus to food. Otherwise, the selected genetic target and the Real-time PCR performed, could have been not so efficient in detecting virus as expected. Conclusions In this preliminary work, food does not seem to be a substrate for Sars CoV2 contamination;other food categories or transformation/production processes could be investigated to confirm the obtained results. Also, different targets and amplification systems would have to be evaluated to verify the rule of foodstuffs as Sars CoV2 vehicles. Key messages Primary production and manual processed food don't seem to be at risk for SARS CoV2 contamination. Food has not been identified as a source of Sars CoV2 spreading.


Nowadays, the thin film deposition process is essential in the semiconductor fabrication process and used extensively in many applications. Progress in each of these areas depends upon the ability to selectively and controllably deposit thin films. This paper proposes a design framework and implementation of the simulation of thin film deposition processes. This presented work focuses on the deposition processes in twodimensional geometries and the simulation is considered in the context of neutral flow Direct Simulation Monte Carlo (DSMC) simulations for semiconductor fabrication. Parallel computing is employed to improve the performance optimization of the system. This paper describes the simulation method and algorithms that are used to implement the simulation on a parallel system and presents the results of thin film deposition simulation.


Primary retroperitoneal tumors are a heterogeneous group of neoplasms with a prevalence of 0.02 to 1%. The results of diagnostic visualization of such tumors are usually ambiguous due to their diversity and similar radiological semiotics of malignant and benign tumor types. The paper describes a rare case of the diagnosis and management of a patient with one of retroperitoneal tumor, i. e. a giant intramuscular hemangioma.
A 23-year old male patient was referred with complaints of episodic pains in the right inguinal area for 78 years. The multiaxial computed tomography showed a mass of 145 125 125 mm located in the trunk and pelvis, and spreading to the right thigh. The tumor structure was markedly heterogeneous and contained calcinates, adipose tissue, soft tissue and vascular components. The mass showed a heterogeneous contrast accumulation, with predominant delayed-phase enhancement. The tumor was surgically resected, with the histological investigation characteristic of intramuscular hemangioma.
Rare retroperitoneal tumors are always challenging in the interpretation of the results of diagnostic visualization. Since their various types have similar radiological semiotics, the differential diagnosis is often impossible. Therefore, the main diagnostic issue should be the exact localization of the neoplasm, identification of the feeding vessels, and the assessment of the adjacent tissue abnormalities.

Millions of users rely on star ratings to decide which app is the best. However, it is not clear if there is a correlation between star ratings and how usable the apps are. In other words, there is a need to study if a better star rating means a better level of usability. The current study conducted an experimental study with 30 participants who were given three different apps with different star ratings (low-medium and high). Three sessions were recorded for every participant. In every session, an array of three tasks was performed. During each session of the usability experiment, quantitative data about the time taken to complete each task, task success, and the number of errors was collected to evaluate the factors: efficiency and effectiveness. After each session, the participant evaluated the app by answering a System Usability Scale (SUS) survey to evaluate the satisfaction factor. The results showed no correlation between user star rating and the usability of the tested apps. Additionally, the results showed no correlation between user star rating and any of the tested factors taken separately.

On this point zakat productive program can be developed more broadly and with more scheme, so that more recipients of zakat can join this program and got more welfare and a good living.


Markov and quantum information processing models are compared with respect to their capability of explaining two different puzzling findings from empirical research on human inference and decision making. Both findings involve a task that requires making an inference about one of two possible uncertain states, followed by decision about two possible courses of action. Two conditions are compared: under one condition, the decisions are obtained after discovering or measuring the uncertain state; under another condition, choices are obtained before resolving the uncertainty so that the state remains unknown or unmeasured. Systematic departures from the Markov model are observed, and these deviations are explained as interference effects using the quantum model. Quantum computing and information theory (Neilsen & Chuang, 2000) provides exciting new possibilities for computer science. But what importance does this new theory have for cognitive science? This is a question that is beginning to be asked by an increasing number researchers from a variety of fields including language (Gabora & Aerts, 2002), decision making (Bordley, 1998; Haven, 2006; LaMura, 2006; Mogiliansky, Zamir, & Zwirn, 2004) game theory (Eisert, Wilkens, & Lewenstein, 1999; Piotrowski, & Sladkowski, 2003) and neural nets (Gupta & Zia, 2001; Pribram, 1993). Recently, we (Busemeyer, Matthews, & Wang, 2006) used quantum information processing theory to explain a puzzling decision making phenomenon discovered by Tversky and Shafir (1992). Here we show that this same quantum explanation can also explain another (seemingly unrelated) finding from decision making discovered by Townsend, Silva, Spencer-Smith, and Wenger (2000). Both findings point to a fundamental interaction or entanglement between inference and decision. The Disjunction Effect Our first attempt to model interactions between inference and decision was based on an intriguing phenomena discovered by Tversky & Shafir (1992, see also Shafir and Tversky , 1992). An experiment was conducted in which participants were asked to play a gamble of the form 'equal chance to win $200 or lose $100.' The unique aspect of this experiment was that the participants were also told that they would have an opportunity to play the gamble twice. The first play was obligatory, but they could decide whether or not to play the second time. Three conditions were investigated: in the known win condition, they were told that they won the first play; in the known lose condition, they were told that they lost the first play; and in the unknown condition, they were not told the outcome of the first play. This manipulation is designed to test the 'sure thing' principle that lies at the foundation of utility theory (Savage, 1954): If you prefer to gamble the second play knowing that you won the first play and you prefer to gamble the second play knowing that you lost the first play, then you should prefer to gamble the second play even when you do not know the outcome of the first play. Shafir and Tversky (1992) found that players frequently violated the sure thing principle – most players chose to gamble the second play knowing that they won the first play (69%), and they also chose to gamble the second play knowing that they lost the first play (59%); but they switched and chose not to gamble when they did not know the outcome of the first play (36%). Next we will consider two alternative models for this phenomenon. The first is based on Markov probability theory, and the second is based on quantum probability theory. We formulate the models in a parallel manner in order to clearly see the common and distinctive assumptions of the two models. A Markov Information Processing Model To construct a Markov model for this phenomenon, we postulate that there are two states of beliefs about the outcome of the first play: win or lose. Additionally, there are two states of action for you to take: gamble or not. We assume that a person can simultaneously consider beliefs and actions which then produces four basis states denoted {|WG〉, |WN〉, |LG〉, |LN〉}. For example, |WN〉 represents the case where you simultaneously believe that you won the first play but you do not intend to gamble on the second round. The state of the cognitive system (that is, the part needed for modeling this task) is represented by a 4 × 1 column vector ψ = [ψWG, ψWN, ψLG, ψLN]. According to Markov theory, this state vector is a probability distribution across the basis states. For example, ψWN represents the probability of the Markov system being observed in state |WN〉. The elements of the state vector must sum to unity to guarantee that it forms a proper probability distribution. The state of the cognitive system is changed by thoughts generated by interacting with the environment. In terms of the Markov model, a thought is represented by a transition operator, denoted T, which changes the state from one vector ψ to another φ = T⋅ψ . For this application, the transition operator is represented by a 4 × 4 matrix T with elements that satisfy 0 = Tij = 1, and ∑iTij = 1. These constraints guarantee that the new state φ remains to be a probability distribution. The initial state vector represents the state of the cognitive system at the beginning of each trial. This initial state is changed by information given to the player. If the player is informed that he/she won the first gamble, then an operator T is applied to transform the initial state into one that has ψLG = ψLN = 0 producing ψW = [αW,βW,0,0], where βW= 1 αW. If the player is informed that he/she lost the first gamble, then another operator is applied that transforms the initial state into one that has ψLG = ψLN = 0 to produce ψL = [0,0,αL,βL], where βL = 1 αL. In the unknown case, the state remains mixed: ψU = p⋅ψW + q⋅ψL, where p and q = (1−p) are the mixture probabilities. To select an action, the player must evaluate the probabilities and payoffs of the gamble. Thus the state ψ is processed by a transition operator Tt for some period of time t, which transforms the previous state into a final state φ = Tt · ψ, which produces a column vector φ = [φWG, φWN, φLG, φLN]. For example, φWG is the final probability of gambling the second play given that the player is known to win the first play. The final response probabilities are obtained by projecting the final state vector onto the subspace consistent with an observed response. Define M as a 4 × 4 measurement matrix with the first row equal to [1 0 0 0] and the second row equal to [0 0 1 0], and the last two rows equal to zeros. The product φ = M⋅φ produces a 4 × 1 vector that represents the projection of the state onto the bases that lead one to choose to gamble on the second play. Finally, define L = [1 1 1 1] as a row vector of ones, then L⋅φ = φWG + φLG gives the total probability of gambling on the second play. The Markov strategy Tt can be constructed from an intensity matrix K as follows: Tt = exp(t·K). (This uses a matrix exponential function, which is available in MatLab or Mathematica). The processing time parameter, t, is a free parameter in the model, but it can be manipulated by deadline pressure. The intensities must satisfy k ij ≥ 0 for i ≠ j and ∑ik ij = 0 to guarantee that exp(t·K) is a transition matrix. We use an intensity matrix that has the following general form: the off diagonal elements k21 ≠ k12 and k43 ≠ k34 allow probability flow across two actions within each belief state; the interactions between beliefs and actions are modeled by allowing flow between actions that match beliefs, k41 ≠ k14. The diagonal values are set equal to k11 = −(k21 + k41), k22 = −k12, k33 = −k43, and k44 = −(k14 + k34). The remaining elements within K are assumed to be zero. To see how the model works, first consider a special case in which the initial state is uniform (ψ = [1 1 1 1]/4) and the interactions between beliefs and actions is turned off (k14 = k14 = 0). In this case, the preferences for the two actions evolve independently and separately for each belief state. For example, setting k12 = k34 = .10, k21 = k43 = .01, and k41 = k14 = 0 produces a bias to choose to gamble. The probability of choosing to gamble grows systematically from .50 to .91 across time, and the probability of choosing not to gamble decreases from .50 to .09 across time. Failure of the Markov Model It is simple to prove that the Markov model cannot, in general, explain the disjunction effect. If the first play is known to be a win, then we obtain L⋅φW = L⋅MφW = L⋅M⋅TtψW; and if the first play is known to be a loss, then we obtain L⋅φL = L⋅MφL = L⋅M ⋅TtψL. During the unknown condition, we obtain L⋅φU = L⋅MφU = L⋅M⋅TtψU = L⋅M⋅Tt(p⋅ψW + q⋅ψL) = p⋅L⋅M⋅TtψW + q⋅L⋅M⋅Tt ψL = (p⋅L⋅φW + q⋅L⋅φL). The last line states that the probability of gambling in the unknown case must be the average of the probabilities of gambling in the two known cases. However, Tversky and Shafir (1992) reported a gambling rate equal to 36% for the unknown state, which fell far below the range defined by the two known states: 69% when the other player was known to win and 59% when the other player was known to lose. This finding contradicts the Markov processing model. A Quantum Information Processing Model To construct a quantum model for this phenomenon, we again postulate that there are two states of beliefs about the first play: win or lose. Additionally, there are two states of action for you to take, again gamble or not. Again we assume that a person can simultaneously consider beliefs and actions which then produces four basis states denoted {|WG〉, |WN〉, |LG〉 , |LN〉}. As before, |WN〉 represents the case where you simultaneously believe that you won on the first play but you intend not to gamble on the second round. The state of the cognitive system is once again represented by a 4 × 1 column vector: ψ = [ψWG, ψWN, ψLG, ψLN]. According to quantum theory, the state vector is a probability amplitud


A gentleman was walking past a playground and noticed a young boy playing cricket with bat. A colleague of his was bowling. The boy missed the first the second and third, but went on saying 'I am going to hit the next ball'. He noticed the gentlemen and shouted 'See, how I missed three balls, I am going to be the best wicket-keeper in the world'. Well, this is optimism. Likewise this optimism play an important role in every young adult's life for creating a good career, the most important decision one takes in a young adult age is the selection of career. It is one of the most crucial decisions one has to be taken in life. Many educated people in India are unemployed today and it is largely due to unrealistic professional aspirations of the job seeker who continue to seek traditional careers where job opportunities are limited. One has to realize that career is an integrated life long plan of earning a living. Choosing of a career requires meticulous thought, care and planning. While doing so, one has to keep in mind his goals and have a clear idea about the expectations from that career. Education demands a special kind of awareness: one has to have an understanding of what is needed today and what will meet the needs of tomorrow. Education also seek to preserve, transmit and advance knowledge. It is an important instrument for change and progress. The quality of education at the higher level is more important than mere acquisition of a degree. The quality of education of a student depends on his own perception, the teaching standards to which he is exposed, the educational facilities and environment accessible in the institution of his studies and last but not least the student's own temperament and approach to studies. Every young adult have different qualities, different aspects to see their career and different dreams which specify their life but there are some defects in our education system which has been restricted to raised them.


Frequency fast-response functions of the generation units are very important control functions during certain power grid under-frequency or over-frequency abnormal conditions. The proposed frequency fast-response method is based on the changing the condensate flow using the existing turbine cycle condensate storage tanks. As an example, fast decreasing of the condensate flow to the deaerator feedwater storage tank will lead to the decrease of the steam extraction flow to the low pressure feedwater heaters and result in the increase the power output of the unit to support the frequency fast response function under grid abnormal conditions. A theoretical analysis method for evaluation of the fast frequency response under above situation is put forward. Based on the design parameter of the full load condition heat balance diagram, the fast frequency response characteristic of the unit can be calculated. An example of the proposed frequency fast response scheme is provided for a 350MW generation unit. It is shown that under the condition of grid under-frequency abnormal operation condition the condensate flow to the deaerator can be decreased about 40%-55%, and a 2.7%-3.7% of the unit output can be expected under full load condition. It is also shown that for the condensate flow maximum change conditions, the calculated operation duration is more than 5 minutes, which provides a reasonable period for change the coal combustion and operation of the boiler systems to adapt to the grid power change request from the power frequency deviation. The theoretical analysis results also give some operation limitation for future site application.


The objective of this work was to evaluate the strength of four candidate cylindrical shear joints for composite tubes. The basic design for the joint entails an axial length of one inch with an external 15° tapered cone. The purpose of the joint is to transfer axial load from a cylinder through a steel shear attachment with a matching internal coni cal seat. The design candidates consisted of a bonded wedge cone, pinned wedge cone, and a bonded and pinned wedge cone attached to a two-inch diameter composite tube and a wedge cone integrally wound into the tube. The actual joint strengths achieved were higher than expected for some designs and were found to be dependent on the amount of hydrostatic or radial compression applied to the joint. The bonded wedge ring and the inte gral wedge ring both achieved over 96 MPa (14 ksi) of shear strength without failure. Due to the unexpectedly high shear strengths of the joints most of the failures were located in other parts of the test specimen. The bonded wedge cone was probably close to its maxi mum load carrying capacity while the integral wedge design showed potential for even higher shear strengths. The bonded and pinned joint reached a peak shear strength of 78.9 MPa (11.5 ksi) and the pinned only configuration achieved 70.6 MPa (10.3 ksi). When loaded without any hydrostatic compression the joint strengths were less than 34.3 MPa (5 ksi); however, the failure mode was hoop compression buckling of the tube itself as op posed to a joint shear failure.
