Vanadium—20% titanium tubes, pressurized to stresses of 34 and 39 MPa, were irradiated in the Experimental Breeder Reactor (EBR-II) at 700°C to a displacement damage level of 22 dpa. Sections of the tubes were injected with 15 appm He prior to irradiation to determine the effect of helium on the microstructural and creep response of this alloy to irradiation. It was found that helium promoted cavity formation, primarily within existing precipitates, but total swelling remained low. Helium also significantly enhanced creep deformation. The results indicate that the increase in creep deformation in the presence of helium may be very sensitive to stress. *This research was sponsored by the Office of Fusion Energy, U.S. Department of Energy, under contract No. DE-AC05-840R21400 with Martin Marietta Energy Systems, Inc.

DISTWUTWR OF THIS MOMENT IS Introduction Vanadium alloys are of interest as candidate alloys for possible structural applications in fusion reactor devices. One of the advantages of this class of alloy is its potential for use at a higher service temperature than other candidate alloys such as ferritic or austenitic stainless steels. More recently, interest in vanadium alloys has increased because of their inherent low activation following neutron irradiation [1]. Vanadium alloys maintain promising properties following irradiation [2]. As candidate materials for fusion applications, though, one concern that requires investigation, in addition to displacement damage effects, is how the postirradiation properties are affected by the helium production and stress in a fusion environment. Unfortunately, a direct evaluation of simultaneous helium production and displacement damage during neutron irradiation is not possible at present. Therefore, one must resort to techniques which simulate the fusion environment as closely as possible. One such technique, used previously and also in the present study, is to implant helium into the specimens prior to neutron irradiation. In order to make as direct a comparison as possible to evaluate helium effects on the irradiation response of the vanadium alloys, helium was implanted into only a section of the vanadium tubes which were subsequently pressurized and neutron irradiated. In this way, comparisons could be made between stressed regions with and without helium in the same specimen and possible variations among specimens in temperature, neutron spectrum, or preparation would be avoided. The use of helium implantation prior to irradiation has often been used in the past. Examination of tensile properties of specimens preinjected with helium has shown that helium decreases the ductility for a number of vanadium alloys [2,3]. In addition, the preinjected helium promoted cavity formation although negligible total swelling was found [3,4]. In the present study, the helium was injected into pressurized tube samples so that the additional factor of irradiation under stress could be examined. In a similar study on helium injected pressurized tubes of type 316 stainless steel [5], it was found that the helium suppressed swelling. Experimental Procedure The alloy used in the present investigation was vanadium with 20 wt % Ti (V—20Ti), one of the several vanadium alloys being evaluated for potential fusion applications. A list of minor element concentrations in the alloy is given in Table 1. The tubing was manufactured by Superior Tube Company and swaged down to its final size at the Oak Ridge National Laboratory (ORNL). After swaging, the tube was given a final anneal at 900°C for 30 min at -5 x 10~ Pa. The specimens employed in this study were thin-walled tubes pressurized with helium. The tubing had an outer diameter of 4.57 mm and a wall thickness of 0.25 ram. They were approximately 51 mm in length and had welded end caps. Tubes V23 and V24 were pressurized to produce a hoop stress of 34 MPa (5000 psi) at the irradiation temperature, whereas tube V22 had a hoop stress of 39 MPa (5700 psi). The central section (~13 mm in length) of each specimen was preinjected with helium at 20°C at the Oak Ridge Isochronous Cyclotron (ORIC). The end sections of tha tubes contained no preinjected helium. An accelerator energy of 51.6 MeV was degraded with a beryllium wedge-shaped wheel in order to uniformly distribute the helium throughout the thickness of the tube walls. Helium preinjection levels of 15 appm were attained. The tube specimens were then irradiated in the EBR-II at a nominal temperature of 700°C to a dose of 3.9 x io neutrons/m (E > 0.1 MeV), corresponding to a total damage of 22 dpa and a direct helium production of 1 appm [6]. The diameters of the tube specimens were measured after filling with helium (prior to irradiation) and after neutron irradiation. These measurements were made at the Hanford Engineering Development Laboratory (HEDL). After the diameter measurements, the tubes were cut into ring sections corresponding to the regions with and without preinjected helium. Immersion density measurements were made on these ring sections prior to the preparation of TEM specimens. Specimens for TEM examination were cut from the ring sections and ground flat on 600-grit emery paper. The wafers were subsequently jet polished in a 12.5 vol % solution of cone. H2SO1+ in methanol at —25°C and examined in a 100 kV analytical electron microscope. Experimental Results Dimensional Measurements Tube diametar measurements are available for tubes V22 and V24 and the change in tube diameter is plotted in Fig. 1 for both of these specimens. The increase in tube diameter found for both specimens is a combination of plastic deformation and swelling. Except for the last data point in Fig. l(a), which seems to be an outlier, the tube expansion was fairly uniform across its length. A slight increase in the tube expansion may exist in the helium preinjected area. For the tube with the greater hoop stress [V22, Fig. Kb)], a large increase in tube expansion is found in the center section of the tube, corresponding to the region that contains 15 apptn preinjected helium. Thus, for sample V22, it is clear that the presence of helium leads to a larger tube expansion. Density Measurements After irradiation, the three tubes were cut into rings and density measurements were made on these rings from all three tubes. The results are plotted in Fig. 2. Also shown as a dashed line is the density for identical, but unirradiated, ring sections. The data indicate that a slight (1.2%) decrease in density occurs upon irradiation. No significant difference in density is seen between the regions with and without


Context: Women with idiopathic anterior uveitis do not appear to relapse while pregnant. Relapses are reported more frequently and intensely during premenstrual and menstrual stages. These observations suggest that uveitis may be related to fluctuations of sex steroid hormones. Aims: To assess the effect of female sex steroid hormones on the course of idiopathic anterior uveitis. Settings and Design: Comparative study done by retrospective chart review assessing the course of anterior uveitis for 60 patients (30 women each from eumenorrheic and postmenopausal stages) recently seen in uveitis clinic. Methods and material: Retrospective review over one year from the date of the most recent visit after Institutional Review Board approval was obtained. Main outcome measurements were based on severity and duration of the intraocular inflammation. Other outcome measurements included recurrence of flare-up and response to treatment regimens, including steroids and immunomodulatory agents. Statistical analysis: Differences between the number of patients in groups were tested for significance using a chi-square analysis. Results: A higher incidence of uveitis flare-up occurred during the eumenorrheic stage compared to postmenopausal stage of life. The course of uveitis was of markedly increased severity in the eumenorrheic stage. Conclusion: The incidence and intensity of uveitis flare-up is more pronounced during the active reproductive period of life. Differences in typical treatment may reflect the severity of the flare-ups or relate to concerns for side effect profiles amongst the groups. Differences in sexual hormone milieu are likely a major factor contributing to the differences in presentation of uveitis amongst eumenorrheic and postmenopausal women.


We emphasize some implantable "smart", tissue engineering biomaterials and respectively, advanced devices, with important healing potential in spine and/or spinal cord injuries (SCI). There are two main types of such biomaterials: unresorbable and resorbable, separate in two distinct/ intricate cathegories: acellular and - more recent/ complex - construct scaffolds (polymeric/ gel-type, bioactive or/and self-assembling/ nano-processed). They serve as: continuity ("filling the gap")/holding (re)structures, intra-nevraxial neural (re)growth inhibitors' blockers, contains, guides or/and stimulators for neo-forming tissues, delivery vehicles for cells and growth/neuro-protective factors, host immune attack/ reject reactions preventors, cell behavior controllers - including decrease of glial scar formation - or adjunct in bone grafting. Ground-breaking: molding "biological ink" (of micro-inkjet cell aggregates) into 3-D shaped biodegradable polymer gels, to build organs from the ground up (including inside repair/ regeneration). Related reliable trials are on going: they might, in the following about three years, eventually, show consistent improvements of SCI therapy outcomes.

Underpinning the legal-philosophical theories of John Rawls, Edith Weiss, and Hans Jonas, a specific ethical-moral plan was built to guide human interference with nature and its intra and intergenerational responsibility. To this end, based on the major premise of ensuring the dignity of the human person and conducting life in its most varied forms, theories are presented integrating them into the context of environmental natural goods to answer the questions arising from the innovations of the current constitutional text that confers rights to future generations and consequently gives rise to the need for remodeling of classical legal institutes, such as that of liability, which in its classical form does not address the problem in its peculiarities. The questions were conducted through the exploratory research technique, focusing on bibliographic research, with the verification and deepening of the doctrines related to the subject of social fundamental human rights.


A case of a 10-year old boy with an anterior spinal epidural hematoma in the cervical spine is presented. Subsequent to the MR examination clinical and laboratory work-up revealed the child to have a severe form of Hemophilia-A. The intraspinal bleeding was the first manifestation of this disease in the boy; the site of bleeding too was unusual. Subsequent imaging studies after treatment with Factor VIII replacement are also depicted. The pivotal role of MRI in the diagnosis of the hematoma is stressed. In a young male child with these clinical and imaging features, one should investigate the possibility of hemophilia and congenital coagulation defects


Objective: To systematically describe communication between tele-ICU (Intensive Care Unit) nurses and bedside nurses in multiple ICUs, the strengths and weaknesses of communication in the tele-ICU and possible solutions for improving communication. Background: Nurses in tele-ICUs function in virtual teams whose configuration and membership is constantly and rapidly changing. This research examines communication and technological support for communication in the multiple virtual teams formed by tele-ICU nurses and ICU nurses. Methods: A case study research approach using mixed data collection methods. One tele-ICU that monitors 16 ICUs in 12 hospitals across the US participated in this study. Results: Tele-ICU nurses spend 26% of their time in communication-related activities. Fifteen percent of tele-ICU nurses surveyed reported getting incorrect information from ICU nurses and 40% reported that they are not informed in a timely manner about a change in patient status. Frequency of communication between tele-ICU and ICU nurses depends on several factors such as time of day and intensivist coverage in the ICU. Tele-ICU nurses develop and employ unique strategies for communicating with ICU nurses. Conclusion: Tele-ICU nurses use many approaches and techniques when communicating with multiple ICUs. Additional research needs to generalize these findings.

To The Editor, I wish to congratulate Akrami and their colleagues for their article1 in which they investigated clinicopathological features and prognosis of patients with metaplastic breast cancer (MBC) from their region and compare it to patients with triple negative invasive ductal carcinoma (TN‐IDC) and non‐triple negative‐IDC (NTN‐IDC) during a long term follow‐up. A total of 3240 cases were studied which included 3214 patients with IDC (2934 cases of NTN‐IDC and 280 cases with TN‐IDC) and 26 patients with MBC. Percentage of ER and PR positive individuals in the MBC group was 35% for ER and 25% for PR and percentage of HER2 positive patients were 31%. These results were unusual when compared to common literature. My own breast cancer data coming from Ankara, Turkey included 6038 invasive breast cancer patients recorded between 2006 and 2018. Among these cases 13 patients were diagnosed with MBC. In all 13 cases, both ER and PR were all negative. Only two patients with MBC showed HER‐2 positivity. The authors did not mention about detailed information about adjuvant systemic treatment (anthracyclines alone, taxanes alone, or antrhracyline + taxane) which might affect the outcome. Taken all together, my recommendation is to revise hormone receptor cases again and to address treatment schedules that were received by MBC compared to NTN‐IDC and TN‐IDC patiens.

Non-contact generation of ultrasound in materials is often accomplished using pulsed lasers. The rapid heating from the laser pulse produces a thermoelastic expansion in the material that produces the ultrasound. Here we introduce an alternative method, designated Continuous Laser Generation of Ultrasound (CLGU). With sufficient power, a continuous-wave laser can be scanned across the surface of the test material creating an ultrasonic wavefront that propagates through the material. Discontinuities in the wavefront indicate defects in the material. CLGU will have the ability to perform ultrasonic C-scans three orders of magnitude faster than pulsed laser generation.


In the manufacturing of continuously formed products such as metal plates and plastic sheets, on-line monitoring of thickness is important for quality control. Most cases require noncontact measurements. The most widely used optical technique is "optical triangulation" in which a lateral effect position-sensing detector is used. However, the technique has a limited measurement range to resolution ratio making it not suitable for some on-line applications. In this paper we propose a new approach to measure thickness in which the position of a scanning laser beam is timed. It eliminates the restriction of measurement range by the dimension of the detector as in traditional optical triangulation. Also, because small area silicon photodiodes are used, signal-to-noise ratio is largely enhanced thus improving the resolution. The probe we built demonstrates a 47 % measurement range-to-standoff distance ratio and a 2.8x104 measurement range-to-resolution ratio. Also, its performance is not influenced by large changes in object reflectivity.


The availability of arsenic in ground water and potable water accounts many toxic effects on human health because of its high toxicity level; it has become a global concern. Previously to decrease As (III) concentration in water various removal methods were explored. In the present study baker yeast Saccharomyces cerevisiae, used as a biosorbate to remediate the Arsenic (III) in the ground water, its capability was examined to sequester the metal ions from the arsenic contaminated water. Initially yeast was grown in YEPD medium and synthetic solution of As (III) was prepared in 3 different conc. 0.2 mg/l, 0.3 mg/l and 0.4 mg/l respectively. Systematic batch kinetic experiments were conducted with various process parameters such as agitation period, pH, and temperature; all the parameters were studied and found that Saccharomyces cerevisiae had very fine competence towards arsenic removal from the contaminated water under optimized condition of agitation period 120 hours, temperature 55oC and pH 6 were maintained. Removal of As (III) from supernatant was analyzed using the Atomic Absorption Spectrophotometer. It has been found that the percentage removal of Arsenic species (III) increases with decrease in YPD media and Saccharomyces cerevisiae removed 82.2%, 87.8% and 90.46% with respect to different concentration of synthetic solution of As (III) and it is highly effective method for the As (III) removal from the contaminated water.

Planar-type solid oxide fuel cells (SOFCs) developed at Versa Power Systems (VPS) demonstrate high performance, low degradation rates and are well-positioned to meet commercial targets. These cells also perform well when operating reversibly in electrolysis mode for hydrogen production, and remarkable current densities in excess of 6 A/cm2 have been achieved at 800°C with a cell voltage of < 1.67 V. In the present study the effect of operating conditions on degradation rate were investigated, including temperature, current density and steam utilization. The evolution of V - J performance and electrochemical impedance spectroscopy after long-term testing at constant current density is presented and degradation effects analyzed.


A common practice among servers in restaurants is to give their dining parties an unexpected gift in the form of candy when delivering the check. Two experiments were conducted to evaluate the impact of this gesture on the tip percentages received by servers. Experiment 1 found that customers who received a small piece of chocolate along with the check tipped more than did customers who received no candy. Experiment 2 found that tips varied with the amount of the candy given to the customers as well as with the manner in which it was offered. It is argued that reciprocity is a stronger explanation for these findings than either impression management or the good mood effect.


Bio-diesel is produced by mixing vegetable or animal oil with a small quantity of methanol in a process known as esterification. Bio-diesel is a promising nontoxic and biodegradable renewable alternative fuel compared to petroleum diesel in the light of the limited nature of fossil fuel and the environmental concerns. The biodiesel is reported to be sulfur-free, nontoxic, biodegradable oxygenated and renewable. and the characteristics of biodiesel are very close to diesel fuel and some are better than diesel such as higher cetane number, no aromatics, almost no sulfur, and more than 10% oxygen by weight, which reduce the emission of carbon monoxide (CO), hydrocarbon(HC), particulate sulfur oxides(Sox) and volatile organic compounds(VOCs).although there are some advantages of using biodiesel instead of petroleum based diesel that biodiesel blends up to a maximum 5% should not cause engine and fuel system problem. so it can be seen that the properties of biodiesel can affect the engine performance and emissions. So in this paper we discussed anticipating emission and suggestions for reducing exhaust emissions with CNSL as a fuel in CI engine.


The Covid-19 pandemic devastated thousands of lives, causing a health and socioeconomic crisis, with direct effects on increasing poverty and hunger. However, these aspects are rarely associated with semi-hydroponic fruit production and its role in food security. Therefore, the objective of this investigation was to identify a successful case of food production in family farming in a small municipality called Diamante do Sul, located in the state of Paraná, Brazil, which has one of the worst Municipal Human Development Indexes of the state. This article was based on a case study. The data were collected from non-participant observation and a semi-structured interview, applied to a farmer selected by convenience. We verified that the technological innovation of semi-hydroponics represents an excellent alternative for the production of strawberry fruit, in quantity and quality. This production system, implemented through the access to rural credit, besides the fast return on investment, acts in the generation of income for the family and the strengthening of their productive autonomy. Thus, the production of strawberries in times of pandemic famine has an influence on food security and the movement of the local economy, since production occurs throughout the year.


The asymmetric unit of the polymeric title compound, [Ni(C8H4O4)(C10H14N4)(H2O)]n, contains one Ni2+ cation, one coordinating water molecule, one 3,3′,5,5′-tetramethyl-4,4′-bipyrazole ligand and half each of two benzene-1,4-dicarboxylate anions, the other halves being generated by inversion symmetry. The Ni2+ cation exhibits an octahedral N2O4 coordination sphere defined by the O atoms of the water molecule and two different anions and the N atoms of two symmetry-related N-heterocycles. The N-heterocycles and both anions bridge adjacent Ni2+ cations into a three-dimensional network structure, with one of the anions in a bis-bidentate and the other in a bis-monodentate bridging mode. N—H⋯O and O—H⋯O hydrogen bonds between the N-heterocycles and water molecules as donor groups and the carboxylate O atoms as acceptor groups consolidate the crystal packing.


Extracts of mouse spleen and mouse peritoneal macrophages digested human serum albumin (HSA) at pH 3.0 in vitro; the products of digestion gave three different precipitating components as shown by immunoelectrophoresis. The extent to which 125I-HSA was degraded could also be followed by assaying the radioactivity on a paper strip after zone electrophoresis of the HSA digests. The presence of ferritin did not affect the digestion of HSA. Ferritin was not cleaved by the spleen or cell extract at pH 3.0, 4.5 or 8.0, even after incubation at 37dC for 24 hours. These results are discussed in relation to the fate of the antigens in vivo.


Abstract : After a discussion of the two major elements of the equipment dealt with in this report, two different methods to control the signal frequency by utilizing the information contained in the output signal of the bridge are described. Although this is not a limitation, the methods are explained using one particular type bridge, the Hewlett-Packard Model 803A VHF Impedance Bridge. The same principles can be employed for many other test circuits.


Radiotherapy is a method of externally cancer therapy using a Linear Accelerator (LINAC) tool. LINAC can produce photon and electron beam energy which will be used to treat cancer according to the position of the cancer in the patient's body. When using an electron beam to treat cancer on the surface of the skin, it is found that there is a lack of a radiation dose. The use of bolus with Silicone Rubber (SR) material is a solution to provide an increase in radiation doses in the surface area of the skin. In this study SR boluses were made using the sol-gel method with dimensions of 17 cm x 17 cm x 1 cm. The SR Bolus was illuminated with an applicator field area of 10 cm x 10 cm and energy variations of 5 MeV and 7 MeV. The surface dose produced at the moment without using a bolus for 5 MeV and 7 MeV energy is 1.60 Gy and 1.61 Gy. When using bolus, the surface dose of 5 MeV and 7 MeV energy is 2.12 Gy and 2.06 Gy. From the results of this study it can be concluded that the use of SR bolus can increase a higher surface dose without using bolus.

The estimation of the orientation of an object, and a human head in particular, can be defined by the Euler angles: the yaw, pitch and roll. The robust and drift-free estimation of those angles is usually achieved with the data from several sensors such as accelerometers, gyroscopes and magnetometers, processed with sensor fusion algorithms. However, wearable devices such as hearing instruments are rarely equipped with all those sensors, and might usually only have a single accelerometer embedded per device. While it is possible to retrieve a correct estimation of the roll and pitch using only a single accelerometer, estimating the yaw is a more challenging task as accelerations around the gravity vector cannot be detected by an accelerometer. In the context of binaural communication devices and spatial hearing, the yaw of the head is a key information that helps achieving dynamic binaural synthesis. This work proposes an algorithm that aims at estimating the yaw of a human head by using only two 3-axis accelerometers that are placed at each side of the head. The algorithm is evaluated with acceleration measurements of human subjects achieving a realistic task. The results suggest that the strategy used is promising as a good performance can be achieved for a majority of the measures as long as an individualized set of parameters can be selected. The results also suggest that the performance of the current implementation is sensitive to sensor displacement after calibration or a wrong estimation during initialization.


Background Now more than ever before, air pollution and cognitive decline are global concerns. Credible links are now emerging between exposure to specific pollutants and cognitive decline. However, the role of specific pollutants on different cognitive domains in adults are inconclusive as the pathways to cognitive decline remain poorly understood. Objective To systematically review and meta-analyse the evidence for the association between long-term air pollution exposure and cognitive function in adults. Data sources Web of Science, PubMed, Embase searched up to February 2021 with no language restrictions. Individual studies were identified from similar review articles. Eligibility criteria Studies investigating the long-term (>3 years) associations between airborne pollutants and cognitive function in older adults (>50 years old). Results From 1996 records, 26 satisfied the inclusion criteria. The total sample size included over 2.4 million (53.8% female) subjects with ages ranging from 45 to 100 years (estimated mean age 70 years). Only 18/26 publications included both male and female subjects. Pollutants reported included particulate matter ≤2.5 µm (PM2.5); particulate matter ≤10 µm (PM10); nitrogen dioxide (NO2); nitrogen oxide species (NOx) and ozone (O3). Papers showed great variance in their study characteristics, air pollution modelling methodology and assessment of cognitive domain. Long-term exposure to increased levels of PM2.5 and NO2 were most strongly associated with increased risk of dementia. Decline in cognitive function, executive function, memory and language were most strongly associated with greater exposure to PM2.5, PM10 and NO2 to varying degrees. Conclusion An increasing number of studies are supporting the hypothesis that greater exposure to air pollutants is associated with decline in cognitive functions.


A brief account is given of the physical limitations which influence the power output of stationary and rotating anode x-ray tubes used in crystallographic work. Brief mention is made of various tubes which incorporate rotating vacuum seals in the anode assembly. An account is then given of the "Peristron" dagger, a continuously water-cooled rotating anode x-ray tube which completely dispenses with the need of rotating vacuum seals. Incorporated in the tube is a novel type of cathode assembly which permits of rapid adjustment to the focus from outside the vacuum envelope.

OBJECTIVES
The purpose of this study was to determine the risk factors for caesarean sections in the second stage of labour after a previous caesarean section among women who underwent trial of labour (TOL).

MATERIAL AND METHODS
From a total of 639 women who experienced one caesarean section, 456 women were qualified for TOL. From this group, 105 women were subjected to a caesarean section in the first stage of labour and another 351 women reached the second stage of labour. From the latter group, 309 women delivered naturally and 42 were subjected to a caesarean section.

RESULTS
Risk factors for the necessity of performing a caesarean section in the second stage of labour after a previous caesarean section was the weight gain during pregnancy (OR = 1.07), the height of fundus uteri (OR = 1.25) before delivery, and the estimated foetal weight (OR = 1.01), a past delivery of a child with a birth weight exceeding 4.000 g (OR = 2.14), the presence of pre-gestational diabetes (OR = 15.4) and gestational diabetes (OR = 2.22), necessity of applying a delivery induction (OR = 2.52), stimulation of uterine activity during delivery (OR = 2.43) and application of epidural analgesia (OR = 4.04). A factor reducing the risk of a caesarean section in the second stage was a vaginal delivery in a woman's history (OR = 0.21).

CONCLUSIONS
Women should be encouraged to deliver naturally after a previous caesarean section, especially when their history includes a vaginal delivery and if there is no need for labour induction.


This paper reports the results of an experimental program on the effectiveness of ductile fibre reinforced cementitious composites (DFRCC) in retarding the corrosion of steel, corrosion induced damage and post-corrosion structural behaviour of reinforced concrete (RC) columns. Two series RC columns are included in this program. The first series consists of ordinary RC columns that are subjected to an accelerated corrosion regime. The second series consists of two columns that are similar to first two series in every aspect, except that the ordinary concrete in the column is replaced with a ductile DFRCC material. Two types of DFRCC materials are considered: a hybrid-fibre DFRCC containing 1.5 vol.% PVA fibers and 1 vol.% steel fibers and a mono-fibre DFRCC containing 2.5 vol.% PVA fibers. Specimens of the second series are also subjected to a regime of accelerated corrosion. Corrosion damage, including the possible development of spalling and/or delamination, is monitored in each specimen using a specially-fabricated mechanical expansion collar. Based on the collective findings from theoretically-estimated steel losses, visual recordings of corrosion damage, and measurements of the tendency of cover delaminate, it was concluded that the steel reinforced DFRCC columns had a remarkably higher resistance against reinforcement corrosion compared to the ordinary RC columns. The corrosion damaged DFRCC columns also exhibited about 23–64% higher failure load than that of corrosion damaged RC columns and no sign of spalling of cover of columns in the structural test.


We presented an efficient algorithm, fast adaptive flat-histogram ensemble (FAFE), to estimate the density of states (DOS) and to enhance sampling in large systems. FAFE calculates the means of an arbitrary extensive variable U in generalized ensembles to form points on the curve {beta}{sub s}(U) {equivalent_to}{partial_derivative}S(U)/frac/{partial_derivative}U, the derivative of the logarithmic DOS. Unlike the popular Wang-Landau-like (WLL) methods, FAFE satisfies the detailed-balance condition through out the simulation and automatically generates non-uniform ({beta}{sub i}, U{sub i}) data points to follow the real change rate of {beta}{sub s}(U) in different U regions and in different systems. Combined with a U-compression transformation, FAFE reduces the required simulation steps from O(N{sup 3/2}) in WLL to O(N{sup 1/2}), where N is the system size. We demonstrate the efficiency of FAFE in Lennard-Jones liquids with several N values. More importantly, we show its abilities in finding and identifying different macroscopic states including meta-stable states in phase co-existing regions.

Offi cial inspections and certifi cation systems are fundamentally important and widely used. The confi dence of consumers in the quality and safety of their food supply depends in part on their perception of the eff ectiveness of food control measures. A substantial part of the worldwide trade in food depends upon the use of inspection and certifi cation systems. It is desirable that the design and application of these systems refl ect appropriate principles. The aim of this study was to provide a preliminary assessment of the imported food control system in Macedonia and assess its eff ectiveness by exploring the trends in food safety hazards through analyses of the border control of food safety of non-animal origin, in the period of 2005/06 and 2009/10. According the results, the most often prohibited import products were fl our, salt, juices and mushrooms. Foodstuff s imported from Serbia, China and Kosovo were identifi ed as food with potentially high risk. The paper, also, compares Macedonian with European food import control system and certain weaknesses in the food control procedures were identifi ed. The paper gives recommendations for strengthening border control of food of non-animal origin with special concerns of the requirements for an imported food inspection programme based on risk that should be developed using a risk analysis approach.


The height at which overlying strata fail is an important parameter for the prevention and control of mine water damage. High overlying strata failures during mining of a thick coal seam make testing in mines challenging. Considering the mining conditions for the thick coal seam in Ordos City, Inner Mongolia, China, this work applies ground detection using transient electromagnetics. The response characteristics of transient electromagnetic signals during strata failure were investigated using numerical simulation, and the results of that investigation will provide guidance for on-site exploration. In addition, based on the conditions of the ground and mining face, test wires were distributed within the mining work face area to obtain electromagnetic detection data using large wireframes on the ground to further construct an electrical profile of the coal mining and non-mining areas and explain the characteristics of strata failure. This method succeeded in the practical application and is provided as guidance for strata failure detection for thick coal seam mining.


Summary Introduction: Although varicose vein recurrence is common and 10–30 % of all varicose vein surgery is done for recurrence of some sort, there are very few studies that can guide us to the best re-treatment option. With the introduction of minimal invasive endovenous treatments there is a variety of possible options besides traditional open surgical techniques. Method: The Scandinavian Venous Forum held a symposium at the GSP meeting in Lü-beck 2012 and this review article is based on data from the presentations at that symposium. Further data has been added regarding new knowledge that was not available a year ago, from PubMed search and article references. Results: The most common reasons for recurrence are discussed and also the discrepancy between neovascularization (NV) and recurrence due to technical failures. It is likely that NV is the most commonly duplex detected type of recurrence following open groin surgery, less common early after endovascular techniques. However, technical or tactical failures are the most common reasons for redo surgery because of symptomatic recurrence. NV seldom leads to symptomatic recurrences and thus a need for re- treatment. There is a risk that the stumps left following endovenous treatments will become a source for symptomatic recurrence after 5–10 years and indications of that have been reported in the few available 5 year RCT-reports following laser treatments. Treatment of recurrence due to stumps in the groin can be done safely within a reasonable operating time through a medial approach and the stump itself can generally not be treated with any of the endovenous alternative methods. Foam treatment can be used for most other recurrent veins but the durability is unknown. Endovascular thermal ablation can only be used for reopened or remaining saphenous veins and accessory saphenous veins while tributaries have to be treated by stab excisions or foam. Conclusion: Long term reports of results of redo surgery are limited but suggest reasonably good results from open surgical intervention and are non-existent for the endovenous techniques. So far groin recurrence seems best treated surgically by an indirect approach, preferably medial. More studies are needed to find the best treatment regime for varicose vein recurrence in general and hybrid procedures might be the way forward by combinations of different techniques.

The invention discloses a gray forecasting model-based recommending method and a gray forecasting model-based recommending system, and relates to the field of recommending systems. The method comprises the following steps of: establishing an inter-project similarity matrix; selecting a predetermined number of projects having high similarity with unrated projects of a target user from the rated projects of the target user according to the similarity matrix; ordering the scores of the selected projects according to the order of the similarity, from high to low, of the unrated projects to obtain a forecasting sequence; establishing a gray forecasting model according to the forecasting sequence; and forecasting the scores, forecast by the target user, of the unrated projects according to the gray forecasting model, and recommending the corresponding unrated project to the target user according to the forecasting score. By using the recommending method and the recommending system, very high recommending precision can still be ensured when user rating data is extremely sparse and high correlation exists among the data, and the recommending method and the recommending system have a very wide application prospect.


DNN-based video frame prediction can be a powerful tool to improve performance of motion-compensated prediction in video coding. In this paper, we propose a method applying multiple convolution kernels with different sizes to PredNet, which is one of the DNN-based video prediction schemes, to enhance the prediction accuracy by incorporating context adaptivity in its convolutional LSTM layers. We analyze the prediction performance of the proposal, and the results show that applying multiple-size kernels is effective than applying a single-size kernel in terms of prediction error reduction.


Effort during this quarter was devoted to three areas: 1) analyzing the data from earlier runs with �zinc chromite� catalyst and three different slurry liquids: decahydronaphthalene (Decalin®, DHN), tetrahydronaphthalene (tetralin, THN) and tetrahydroquinoline (THQ); 2) analyzing newly-obtained data from earlier thermal stability tests on DHN and THN, and 3) carrying out a thermal stability test on THQ. Both the activity and selectivity of �zinc chromite� catalyst depended on the slurry liquid that was used. The catalyst activity for methanol synthesis was in the order: THQ > DHN > THN. Despite the basic nature of THQ, it exhibited the highest dimethyl ether (DME) production rates of the three liquids. Gas chromatography/mass spectroscopy (GC/MS) analyses of samples of THN and DHN were taken at the end of standard thermal stability tests at 375°C. With both liquids, the only measurable compositional change was a minor amount of isomerization. Analysis of a sample of THN after a thermal stability test at 425°C showed a small reduction in molecular weight, and a significant amount of opening of the naphthenic ring. Preliminary data from the tehrmal stability test of THQ showed that this molecule is more stable than DHN, but less stable than THN.

A driving method, a driver device, and a display device. The driver device comprises: a capturing module (100) used for capturing a frequently touched area of a touch panel and a touch driver module (200) used for scanning and driving the touch panel, where the frequency at which the frequently touched area captured by the capturing module (100) is scanned is greater than the frequency at which other areas are scanned. In the driver device, because the frequency at which the frequently touched area is scanned is greater than the frequency at which the other areas are scanned, given a certain amount of total touch time, the number of times that the frequently touched area is scanned is increased, thus increasing detection sensitivity for the frequently touched area. Other than the frequently touched area, the remaining touch areas have either a low probability of being touched or are not touched at all, though the number of times that said areas being scanned is reduced, user experience is not greatly affected.

The variational approach to the problem of seeking axially symmetric solitons with B=12 is presented. The numerically obtained local minima of the skyrmion mass functional and baryon charge distributions are pointing to the possible existence of shape isomers in $C^{12}$ spectra in the the framework of the original Skyrme model. Theoretical analysis reveals the exclusiveness of each individual state manifested in the structure of the solitons from the given topological sector B=12.


'Patterned' hair loss of the so‐called male type (androgenic alopecia) has long been regarded as a marker of pathological virilization when it occurs in women—an indicator of specific ovarian or adrenal disease. We have believed for many years that patterning is relatively common in normal women, although it is generally masked by the hair styles adopted to convey an appearance of dense hair. Since it is medically important to confirm the physiological nature of female patterning, we carried out a population survey of 564 normal women. The hair density of each subject was carefully examined from above and the hair style flattened or wetted to show the vertex pattern, using the standard grading methods of Hamilton and Ludwig. Thirteen per cent of premenopausal and 37% of post‐menopausal women had detectable Hamilton grades of 2–7 which were not obvious from frontal viewing. We conclude that in the absence of other signs of virilization, patterned alopecia in women is a poor indicator of significant androgen metabolism diseases.


Free polarization decay and photon echo were detected as heterodyne signals in the weak component of radiation, polarized at right angle to the principal part of exciting radiation. Coherent responses were generated in 13CH3F gas by Stark switching of molecular levels in a gas excited by CW CO2 laser radiation at 9P (32) line. The specific features of this technique in comparison with the conventional Stark switching method of coherent transients generation is considered.


The tufa rocks used in sacral buildings in the Etruscan site of Marzabotto (Bologna, Italy) were characterised from a petrochemical point of view and compared with lithologies outcropping in the surrounding area in order to recognise the ancient quarries. These tufa, called "travertini" in the Italian literature, are very porous and are rich of macrophyte moulds revealing an origin by freshwater carbonate deposition (FordPedley, 1996) Facies and thin section analyses show that these rocks were formed in cascade and paludal settings. Hypothesising that the possible quarry areas of travertine rocks were not far from the site and using the geological maps of the surrounding of the Etruscan site it was possible to identify few possible supply zones: 1) San Cristoforo di Labante (Castel D'Aiano, Bologna), 2) Rio Sponga (Marzabotto, Bologna) and 3) Rio Bucamante (Serramazzoni, Modena). Petrochemical characterisation were complemented with a statistical elaboration using the SPSS 14.0 (Copyright © 2006 SPSS Inc.) method and have highlighted that the San Cristoforo di Labante deposit could be the most suitable quarry area of the travertine used in Marzabotto. The geomorphology of the area suggests that blocks were lowered from the San Cristoforo di Labante deposit through a "lizza" way (using rollers along a prepared slope) and then shipped along the Reno River to the Etruscan site of Marzabotto.


Helminth parasites of white-tailed jackrabbits, Lepus townsendi , were surveyed from southern Wyoming and northwestern Colorado. A total of eight helminth species were identified, including two species of adull cestodes, Mosgovoyia pectinata and M. varahilis. three species of larval cestodes, Multiceps serialis. Taenia pisifonnis, and Taenis sp., and three species of nematodes, Dermatoxys veliger, Passalurus ambiguus, and a filariid. MicipseUa hrevicauda . In addition, eggs ofan unidentified species o^Neniatodiriis were found in pooled fecal samples. The cysticercus larva ofTaenia sp . is a species new to science and will be reported elsewhere. Mosgovoyia varahilis anc MicipseUa hrevicauda are new records for the white-tailed jackrabbit. The helminth parasites of the white-tailed jackrabbit are not well known throughout most of its range. Only in North Dakota has any attempt at a survey been made (Voth and James 1965). Additional reports such as those of Honess and Winter (1956) and Thomas and Honess (1962) indicate that helminths occur occasionally in this host but give no information on number of hosts examined or percent of infection. Materials and Methods The hosts for this study were collected from three locations, i.e., near Meeker, Colorado; 20 miles north of Baggs, Wyoming; and 30 miles north of Medicine Bow, Wyoming. All were collected using firearms. Standard parasitological techniques were used for the recovery of helminths. Selected examples of all adult helminths were deposited in the United States National Museum Helminthological Collection (USNM#).

Summary In this report, recommendations for the pharmacological treatment of anxiety and obsessive-compulsive disorders are presented, based on available randomized, placebo-or comparator-controlled clinical studies. Selective serotonin reuptake inhibitors (SSRIs) are the first-line treatment for panic disorder. Tri2-cyclk antidepressants (TCAs) are equally effective, but they are less well tolerated than the SSRIs. In treatment-resistant cases, benzodiazepines like alprazolam may be used when the patient does not have a history of dependency and tolerance. Due to possible serious side effects and interactions with other drugs and food components, the irreversible monamine oxidase inhibitor (MAOI) phenelzine should be used only when first-line drugs have failed. In generalised anxiety disorder, venlafaxine and SSRIs can be recommended, while buspirone and imipramine may be alternatives. for social phobia, SSRIs are recommended for the first line, and MAOIs, moclobemide and benzodiazepines as second line. Obsessive-compulsive disorder is best treated with SSRIs or clomipramine.


We develop a theory for long-distance quantum key distribution based on concatenated entanglement swapping using parametric down-conversion sources and show the numerical results of our model. The model incorporates practical resources including multipair sources, inefficient detectors with dark counts, and lossy channels. We calculate the maximum secret key-generation rate for up to three entanglement swapping stations by optimizing resource parameters. Our numerical simulation shows that the range of quantum key distribution can, in principle, be markedly increased but at the expense of an atrociously unfeasible secret key-generation rate; however, the upper bound of our key rates closely approaches the Takeoka–Guha–Wilde upper bound. Our analysis demonstrates the need for new technology, such as quantum memory, to synchronize photons; our methods should serve as a valuable component for accurately modeling quantum-memory-based long-distance quantum key distribution.


At the preliminary stage of the research, the qualitative analysis of educational editions (textbooks) for visually impaired (blind) junior pupils has been completed. The qualitative analysis of textbooks for secondary and senior pupils receiving school education has given us the opportunity (in this article) to complete the general comparative analysis of educational editions (textbooks) for visually impaired persons receiving general secondary education, who study under the programs of special or mass comprehensive school. The qualitative analysis of educational editions has been completed on the basis of the inquiry among the pedagogues of special comprehensive schools (specialist teachers for the blind and subject teachers) (75% of interviewed) and pedagogues of mass comprehensive schools, that ensure education for visually impaired schoolchildren under the inclusive form of study (25% of interviewed). The geography of the performed inquiry covered most of Ukraine. The modern educational editions (textbooks) for visually impaired persons receiving education, prepared and published within the time period from 2017 to 2021 have been directly analyzed. The analysis covers the textbooks for primary school, printed in the Braille alphabet (for blind pupils) and the enlarged largeprint font (for visually impaired schoolchildren). For secondary and senior classes – only the tetbooks printed in the Braille alphabet. Cross-section data of the inquiry among the pedagogues was followed by own analysis of all editions, mentioned by pedagogues during the inquiry, that being over 100 textbooks for various classes almost in all educational subjects (mathematics, informatics, Ukrainian language and reading, English language, I explore the world – primary school), (Ukrainian language, Ukrainian literature, English language, history of Ukraine, universal history, algebra, geometry, informatics, chemistry, physics, geography, biology – secondary and senior school). The special attention is paid to the main trends, which include preparation, adaptation and edition of educational literature (textbooks) for visually impaired persons receiving general secondary education in Ukraine. The obtained results of the research may change the situation with edition of textbooks for the said category of schoolchildren for the better. Key words: Textbook, the Braille alphabet, enlarged font, persons receiving education, visual impairment, blind schoolchildren, visually impaired pupils.


PURPOSE: A light intensity modulator is described, which can radiate a light wave to a substrate. CONSTITUTION: The photo-intensity modulator comprises a substrate of predetermined material, an optical wave guide formed in the substrate with a curve shape of a circular arc, and an electrode formed to be arranged on a top of the light wave guide. A refractive index is varied according to intensity of an electric field, and the light wave passing through a predetermined spot of the light wave guide is radiated to the substrate by the varied refractive index. Thereby, radiation loss characteristics of a light wave guide having a curve shape of a circular arc is used to attain great modulation depth with the only small variation of a refractive index.

In this paper a microcontroller description in Very High Speed Integrated Circuit Hardware Description Language (VHDL) is presented. An interconnected component-based structure is defined to include most members of a commercial microcontroller family. Every component and the proposed structure were simulated and its results were the awaited ones. Provided that the elements that constitute the microcontroller have the characteristics of a complex system (CPU, Memory and I/O's ports), the physical implementation of a complete model would lead us to obtain a system on a chip (SOC). The whole description also defines an IP module usable in programmable logic designs.

The Melbourne Declaration (2008) set the national priorities for education with a focus on the vital role schools play in social emotional development, thus preparing students for life and citizenship. More than a decade on, there is little evidence to demonstrate how Australian schools are fostering the social emotional development of students. The purpose of this study was to interpret leaders' understandings of student social emotional development and to explore the roles and responsibilities leaders and school staff take. A small scale pilot study was designed and three in-depth interviews of leaders across a K – 12 non-government metropolitan school were conducted. It was found that the leaders prioritised student social emotional development due to a strong belief in the foundational nature of this development to engagement and learning. Leaders and staff across the school work to create a culture of support to foster student social emotional development in order to optimise the conditions for learning. This key finding highlights the need to foster this aspect of student development in a school setting where learning is the primary goal.


In cognitive radio networks with multi-secondary user( SU),resource allocation problem usually simultaneously considers energy efficiency,network coding,and cooperative transmission. For multi-SU resource allocation problem,this paper used Nash bargaining strategy to construct a game,which used the sum of the NBS functions with paring strategy as the optimal objective and the context conditions as the constraints. It improved the system throughput and fairness via the win-win cooperation between the paring secondary users. Then based on this,it proposed an energy efficient sub-optimal resource allocation strategy. Simulation results show that the proposed method has a good tradeoff performance between fairness and energy efficiency,which outperforms the familiar distance-pairing schemes; meanwhile,its computation complexity is lower than the optimal method with ergodic search.

The morphology of the glands was histologically observed,the percentage of integrinα6 β1,CD90. 1 and c-Kit positive cells was examined by Flow Cytometry( FCM). Results: The glands volume was the smallest in LG and the biggest in HG. FCM analysis demonstrated that the percentage of integrinα 6 β1 positive cells in the HG,LG and NG were( 26. 2 ± 2. 4) %,( 16. 9 ± 2. 6) % and( 10. 6 ± 0. 7) %, CD90. 1 positive cells were( 33. 0 ± 5. 4) %,( 25. 0 ± 4. 1) % and( 18. 1 ± 3. 4) %( P 0. 05),c-Kit positive cells were( 13. 4 ± 3. 4) %,( 13. 8 ± 3. 0) % and( 8. 5 ± 3. 1) %,respectively. The percentage of c-Kit positive cells had no statistic difference between HG and LG( P 0. 05),in HG and LG were higher than in NG( P 0. 05). Conclusion: The heat-condition may be more effective to induce the proliferation of integrinα 6 β1 and CD90. 1 positive cells than duct ligation,and similar to duct ligation in proliferation stimulation c-Kit positive cells.


In this paper a novel procedure for the identification of the dynamic parameters of rigid robot manipulators is presented. The method is developed according to the Frisch scheme, an estimation procedure based on a priori assumptions on the data that are different with respect to the usual ones, e.g. to the common Least Square (LS) method. The peculiarities of this scheme give rise to a new way to perform identification on a robot manipulator and offer a better insight of its results with respect to classical methods. A complete and systematic identification procedure is presented involving and improving known techniques of both model reduction and planning of optimal exciting trajectory. Simulation results performed on a 2-DOF robotic manipulator are presented and discussed, confirming the effectiveness of the proposed method.

When an aqueous solution of the 6α-formamidopenicillin BRL 36650 (1) was set aside for 36 h, an essentially quantitative C(5)–C(6) cleavage resulted, yielding the α,α-bis(acylamino) acid (6) and N-formylpenicillamine (10). The unsubstituted phenyl compound (2) behaved analogously, but the 4-aminophenyl derivative (3) showed five-fold greater aqueous stability. Over a wider range of pH, the penicillin (1) was converted into the penillic acid (21) and/or the penicilloic acid (22) at 1 < pH < 7 and into the piperazine ring-opened diacid (23) at pH 10.Both the 6β-aminopenicillin ester (15) and the urethane (24) yielded penicilloates (25) and (26) on base-catalysed methanolysis. However, while (15) was recovered in good yield after prolonged treatment with triethylamine, (24) underwent C(5)–C(6) cleavage, forming the dihydrothiazole (27). These results are interpreted in terms of initial oxazolone formation via the 6β-amido substituent, followed by C(5)–C(6) bond breaking.


Nonlinear analysis in a rotating Rayleigh-Benard system of electrically conducting fluid is studied numerically in the presence of externally applied horizontal magnetic field with rigid-rigid boundary conditions [1, 2]. This DNS approach is carried near the onset of convection to study the flow behaviour in the limiting case of Prandtl number [2]. The flow topology is verified with respect to the Euler number. The fluid flow is visualized in terms of streamlines, limiting streamlines, isotherms and heatlines. The dependence of the Nusselt number on the Rayleigh number, Ekman number, Elsasser number is examined.

Cold-welding and fretting are especially relevant regarding opening and closing of engineering mechanisms, either placed in vacuum or embarked on spacecrafts, because they condition the life of the mechanism and its proper functioning. Fretting may cause wear of materials and coatings which could lead to cold welding. To avoid this risk, the question has to be answered, whether to select smaller radius (risking higher wear leading to big contact area) or select a bigger radius (higher contact area at the beginning). This paper presents the results of a study comparing these both solutions under fretting contact using a steelsteel-contact which is known to cold weld. Different contact situations (geometry/contact pressure) were compared under "realistic" contact situations. Finally, a short introduction to the new "Cold-Weld-data base" will be given: it offers a collection of all cold welding data obtained so far and can be accessed via WEB. On spacecrafts, a variety of engineering mechanisms exhibit ball-to-flat surface contacts which are periodically closed for several (thousands of) times. Impact or fretting may degrade the mechanism's surface layers whether they are natural oxides, chemical conversion films or even metallic coatings. This can dramatically increase the tendency of these contacting surfaces to "cold-weld". Impact may lead to plastic deformation of the substrate, as contacts are often modelled only as static. This may lead to breaking of surface layers. Fretting wear may be caused by vibrations occurring during launch or during movement of e.g. antennas in space. Wear due to fretting was found to be much higher than due to impact and adhesion forces may increase by factor of ten compared to impact conditions ! In order to set-up experience in these effects, two special devices - called "impact facility" and "fretting facility" – were developed at AIT (formerly ARC Austrian Research Centers) and were used to investigate several combinations of bulk materials and coatings for their tendency to "cold-welding". The test philosophy is based on repeated closing and opening of a pin-to-disc contact. During a fretting test, the contact is closed softly and while being closed, fretting is applied to the contact. The adhesion force, i.e. the force required to reopen the contact, is measured at each opening. Several studies have been performed in the past years, investigating the "materials influence", i.e. different material combinations were tested, showing e.g. that stainless austenitic steels show higher adhesion than e.g. chromium steels, or that use of dissimilar materials show reduced adhesion. Several coatings were, investigated for their ability to prohibit cold welding. In most cases the coatings were broken under fretting, thereby setting free the metallic substrate. At this point, both metallic substrate come into contact, and adhesion between both contact partners start. Finally, the adhesion forces may exceed the available separation forces and the mechanism might be blocked by cold welding.


Extensive survey to detect and identify phytoplasmas associated with Chilean grapevines was performed from 2003 to 2005 sampling symptomatic or asymptomatic grapevine plants. Nested PCR amplification allow the detection of phytoplasmas in 28 out of 90 samples. RFLP analyses identified phytoplasmas as belonging to ribosomal subgroups 16SrI-B, 16SrI-C, 16SrVII-A and 16SrXII-A. Cloning and sequencing of selected strains allow to detect genetic variability in 16SrXII-A strains.


Therefore, the study aims to investigate the interrelationship between spatial configurations of El-Tahrir Complex Plaza and users' behavior. In other words, this study investigates the impact of plazas' spatial configuration on user's activities within the plaza, aiming to identify physical and syntactical aspects that affect users' behavior, and led to space underutilization, and dispersal of users within the plazas. Space Syntax techniques were used along with various observational methods, including gate counts, and movement traces to identify the spatial and social properties of the plaza by measuring the accessibility and visibility values. By superimposing observation maps onto syntactical maps, the results showed that integration correlates strongly with pedestrian movement, and that visual integration correlates moderately with static activities, indicating that syntactic measures are a good predictor of human behavior. Thus, Space Syntax can become a vital tool for urban designers aiming to enhance utilization of urban plazas. Accordingly, a number of design alternatives were tested and compared and an alternative was chosen for its likeliness of improving space utilization.

ABSTRACT This research aims to address the gap in the literature about instructor's role in increasing students' affective engagement (with their peers and instructor) in an online class. Since marketing students will eventually fulfill roles that engage consumers with the firm's communication mediums, it is important to understand the impact of student engagement and peer-to-peer communication in marketing classes in building this skill. Additionally, because of the pandemic, majority of higher education was migrated to online and virtual formats, investigating techniques that can improve the quality of online teaching is more important than ever. The impact of instructor competence in designing and facilitating online classes has been studied before; yet we establish that instructor online competence has an indirect positive effect on students' impression of the quality of their online learning experience. Further, this relationship is mediated by how students are engaged in class through communication with peers and instructors. This research clarifies the effect of instructor affective engagement skills as a contributor to marketing student perceptions of quality and offers several recommendations that act as guidelines for instructors delivering online courses.


We report the operation of a β‐BaB2O4 singly resonant optical parametric oscillator broadly tunable in the ultraviolet, visible, and infrared regions of the spectrum. This optical parametric oscillator was pumped at 266 nm and was continously tunable throughout 0.33–1.37 μm. A novel cavity design was implemented which has applicability to other parametric oscillators. The oscillation threshold of this device was measured and compared to the calculated result.


Take fresh pork as raw material,make sausage with traditional Chinese-style method and detect the changes of different physicochemical indexes of finished sausage at regular intervals.The results show that:with the time extends,the moisture content,pH value,red value reduce gradually and fat content increases gradually.In addition,the acid value,POV value and TBA value caused by oxidation hydrolysis of fat increase gradually.The variation trends of test indexes indicate that natural air drying and storage do not help to the quality advance of sausage and the improvement measures should be adopted.


In recent decades the probation service has been encouraged to work closely with a range of public and voluntary sector agencies. This article examines probation's changing relationships with the police and prison services drawing on sixty interviews with current and former probation workers. Analysing probation-prison and probation-police relationships pre- and post-1998 and drawing on Davidson's (1976) typology of inter-organisational relationships, the article argues that, despite both structural and cultural transformations, there remain cultural continuities in each organisation that create tensions, the significance (both positive and negative) of which should not be under-estimated.

Changes in the Bamileke agricultural sector (West Cameroon) have been very important since the mid 80s, marked by a fall in the prices of coffee, by then the main production of the Bamileke region, and next by the economic crises in Cameroon. In this thesis, the concept of dispositive (Foucault, Moisdon, Maugeri, RIDT-INRA) is the main tool for the analysis of this agricultural sector. A dispositive is a heterogeneous whole that is made up of human, material, non human and immaterial components which are linked to one another and interact with one another and with external factors of the dispositive and these processes leading to observable changes. This research in the Bamileke country enables us to distinguish and study four types of dispositive : that of traders, NGOs, the state and the UCCAO (Central Union of Agricultural Cooperatives of West Cameroon). Those four do not cooperate amongst themselves and are often structured into chains from the regional level to the level of the farmers and are also dependent on actors at national and international levels. As such, dispositives organized by agricultural input traders each include an international agrochemical firm, a cameroonian importer, wholesalers, retailers and small local hawkers or retailers. The intermediation dispositives, be it NGOs or by the state (through the services of the Ministry of Agriculture and national projects/programmes), go from international donors to common initiative groups (CIG) and their members. UCCAO used to collect/collects for export through its divisional cooperatives and local warehouses. These dispositives are highly influenced by foreign donors (those of the state and those of NGOs), they are also selection and constraint dispositives and offer funding, equipment and other types of support. These concern only a limited number of farmers through their peasant organizations and the search for international funding is a principal determinant of the strategies of the actors involved. The set ups promoted by input traders are tools for market expansion and diffusion of technical advice to their customer farmers. They reach out to a large number of farmers and have the particularity that they are very close to individual farmers. However, the logic of profit and competition often influences the advice that is given.

Fabrication of the printed memristors and their memristive behavior have been presented for different metal-insulator-metal (MIM) structures. The printing techniques studied for the current work includes electrohydrodynamic printing (EHDP) and roll-to-plate. The materials used for the electrode deposition are silver (Ag) and indium titanium oxide (ITO) while zirconium oxide (ZrO2) and graphene oxide (GO) have been used for the sandwich layer between two electrodes on a polyimide (PI) substrate. Electrically stable bipolar resistive switching behavior of all the MIM structures with significant Off/On ratio has been observed. The analysis regarding device dimensions and its current voltage (IV) behavior with respect to the employed printed electronic techniques confirms their feasibility for the cost-effective memristive device fabrication.


The phenotypes clinical features and prognoses of 35 cases all wereanalysed. The results showed that all can be divided into five groups: CALL, T-ALL, N--ALL, C/ T-ALL and hybrid acute leukaemia (HAL). The C-ALL and N-ALL had better prognosis and lower WBC count then T-ALL, and HAL,. The C-ALL included two type: B1 or B1+; T-ALL included three in trathymic stages, N-ALL can be divided into three different origh of cells. The authors Suggested it is more suitable to divide ALL into T-ALL (three stages) and Non-T-ALL (six groups).

I will discuss our process of creating and updating our best practices and demonstrate the Metadata Portal we built to display them.


In this paper we investigate the impact of collateral posting on derivative prices. We build a complete discounting framework from vanilla swap pricing to single currency exotic option pricing. We show how to extract initial discount and forecast curves from the market of OIS and IR Vanilla swaps. We extend our considerations to the case of collateralisation in a currency other than the transaction denomination currency.
