Cross Comparisons of CFD Prediction for Wind Environment at Pedestrian Level around Buildings Part 1 Comparison of Results for Flow-field around a High-rise Building Located in Surrounding City Blocks

CFD is being increasingly applied to the prediction of the wind environment around high-rise buildings. However, the prediction accuracy and many factors that might affect simulation results are not yet thoroughly understood. In order to clarify ambiguities and to provide a guideline for CFD prediction of the wind environment, a working group was organized by the Architectural Institute of Japan. This group has carried out various comparative studies as follows. ・First stage: Flowfields around two types of single high-rise buildings. ・Second stage: Flowfield around a high-rise building located in a city. ・Last stage: Flowfields around two types of Building Complexes in actual urban areas. This paper describes the cross comparison results of the second stage. A high-rise building(25 ×25×100m) is surrounded by low-rise city blocks(40×40×10m). Wind tunnel experiments in a boundary layer using split-film probe were carried out by the present authors to obtain data for assessing the accuracy of CFD results. In the CFD simulations, the influence on prediction accuracy of calculation conditions such as boundary condition for ground surface, size of side and upper calculation region, grid system, range of surrounding city blocks, and turbulence models were investigated, and are discussed in detail.

Effect of Acupressure on Physical and Psychological Health Status of Elderly with Knee Joint Osteoarthritis

Background: Acupressure is a type of complementary and alternative medicine that is currently recommended in osteoarthritis management. Acupressure can improve the mobility, self-care practices and quality of life of the elderly with knee osteoarthritis, reduce the elderly patient's dependence on conventional therapy and reduce the burden on society. Aim: Determine the effect of acupressure on physical and psychological health status of elderly with knee joint osteoarthritis. Design: Quasi-experimental research design was used in this study. Setting: The outpatient clinic of Rheumatology in Mansoura University Hospital. Subjects: This study was carried out on 104 elderly diagnosed with knee osteoarthritis and divided into two groups (study and control), fifty-two (52) subjects for each. Tools: Five tools were used in this study; structured interview schedule, western ontario and McMaster universities osteoarthritis scale, hospital anxiety and depression scale, older adult's knowledge related knee osteoarthritis and acupressure structured interview schedule, and acupressure training observational checklist. Results: The majority of the two groups were young old with the mean of age 64.46±4.10 and 65.85±4.54 years for the study and control groups respectively. The total mean score of physical health status (WOMAC score) and psychological health status (Anxiety and Depression) was improved significantly in the study group at post 1 and 2 of evaluation (p=0.000).

BGA RE-BALLING FROM PB-FREE TO SN-PB METALLURGY

As a result of a global movement away from using Lead (Pb) in electronic assemblies, component manufacturers are almost exclusively providing lead-free parts to satisfy the high volume consumer markets. Unfortunately, relatively little is known about the performance of lead-free solders in harsh vibration and shock environments. These concerns are amplified because the consumer industry is currently evaluating another generation of lead-free solder alloys in an effort to improve reliability. Tin whiskers not withstanding, nearly all the current lead-free electronic piece-part termination finishes are compatible with tin-lead assembly solder with the exception of ball grid arrays. Reprocessing lead-free BGAs with tin-lead ball metallurgy is one means of mitigating the risk of lead-free solder material failure modes such as tin whiskers, high cycle fatigue, printed circuit board pad cratering, and intermetallic fracture. In addition, because qualification of a metallurgy change in a high reliability application can take years, BGA reballing allows original equipment manufacturers to maintain the certification and qualification status on existing configurations while managing the on-going lead-free alloy changes occurring on BGAs. In the present work, an assessment of the mechanical integrity of four different commercially available BGAs was evaluated after reballing using visual inspection, cross-section evaluation, scanning acoustic microscopy, moiré interferometry, ball shear, ball pull and assembly level thermal cycling.
OVULATION SYNCHRONISATION FOR IMPROVING FERTILITY IN POSTPARTUM DAIRY COWS

The aim of the study was to evaluate the different ovulation synchronisation protocols for improving fertility in postpartum dairy cows. The work was conducted in 28 lactating crossbred cows at University Livestock Farm, Mannuthy starting on day 40 postpartum (day 0) in three experimental and one control group comprising seven cows each.The cows in Group I (Ovsynch group) were administered GnRH on day 0 followed by PGF2á on day 7 and a second dose of GnRH on day 9. Cows in Group II (Doublesynch group) were administered PGF2á on day 0, GnRH on day 2, a second PGF2á on day 9 and a second GnRH on day 11. Cows in Group III (CIDR group) were inserted with CIDR followed by administration of GnRH on day 0. The CIDR insert was removed and PGF2á administered on day 7 and a second dose of GnRH on day 9. Timed artificial insemination (TAI) was performed 18 h after the second GnRH injection in all experimental groups. Cows in Group IV (Control group) that showed natural postpartum oestrus after day 0 were inseminated at detected oestrus. Pregnancy diagnosis was conducted 45 days post AI by transrectal palpation. The first service conception rate in animals of groups I to IV were 42.86, 28.57, 42.86, 28.57 per cent and the overall conception rates were 71.43, 71.43, 85.71, 57.14 per cent, respectively. The results demonstrated that the CIDR progesterone insert protocol with highest overall conception OVULATION SYNCHRONISATION FOR IMPROVING FERTILITY IN POSTPARTUM DAIRY COWS* P. S.

Bibin Becha6 Department of Animal Reproduction, Gynaecology and Obstetrics, College of Veterinary and Animal Sciences, Mannuthy-680 651, Thrissur, Kerala rate was superior to Ovsynch and Doublesynch protocols. However, Ovsynch and Doublesynch protocol had better overall conception rates than control. Hence it is recommended that ovulation synchronisation protocols viz., Ovsynch, Doublesynch and CIDR can be effectively employed for improving the fertility in post partum dairy cows.
Pestalotiopsis kunmingensis sp . nov . , an endophyte from Podocarpus macrophyllus

A study on the fungal diversity of Pestalotiopsis species occurring on Podocarpaceae yielded an unknown species, which is described here as Pestalotiopsis kunmingensis. This species that occurs as an endophyte, was isolated from Podocarpus macrophyllus. It shares similar morphological characters to other Pestalotiopsis species, but possesses long apical appendages that are knobbed (spathulate) at the tip, a single branched basal appendage and versicolorous median cells.
EFFECT OF LOCAL METAKAOLIN ON PROPERTIES OF CONCRETE AND ITS SULPHURIC ACID RESISTANCE

Recently, there is an energy crisis in Egypt. The Portland cement industry is a highly energy intensive process requiring about 112 k.w of energy-per ton of finished product. Therefore, the efforts should be made to find alternatives for Cement. Supplementary cementing materials (SCM) play an important role in the production of high strength and high performance concrete. In recent years worldwide, metakaolin (MK) has been studied because of its high pozzolanic properties. MK is obtained by the calcination of kaolinite. The raw material input in the manufacture of MK is kaolin. Although Egypt have a large reserve of kaolin however, MK is not widely produced and used due to the lack of adequate experiments. Therefore in these study local kaolins was thermally treated at specified conditions at 750˚C for three hours to produce what so-called MK material.This study investigates the influence of using two types of local metakaolin as supplementary cementing material on properties, strength and durability of concrete and compared with the performance of ordinary (control) and silica fume. The experimental study was carried out in two stages. The first stage consists of 14 concrete mixes from the two obtained types of metakaolin, MKA and MKB and in addition to silica fume (SF) with various percentage (8%, 12%, 15% and 20%) as partial replacement by cement weight to study fresh properties of concrete in terms of unit weight, compacting factor and slump (Superplasticizer Dosage), as well as the hardened properties in terms of compressive strength, water absorption and Porosity. The second stage in this research, investigated the effect of two metakaolins and comparing with silica fume as well as type of cement on concrete resistance to 3% sulphuric acid attack by measuring the percentage of mass loss and percentage reduction in compressive strength after 30, 60 and 90 days of acids immersion.Results show that similar to silica fume, Egyptian metakaolin can be considered as an effective pozzolanic mineral admixture where, metakaolin replacement of cement is effective in improving the fresh and mechanical properties of concrete. The optimum dosage of metakaolin, as a partial cement replacement is 15 to 20% for the used fineness in this study at W/Cm ratio 0.4. It achieves an increase in compressive strength by 25% as compared to control ones, as well as it has the lowest water absorption. A beneficial effect was found by incorporating combination of two admixtures 20% silica fume with 15% metakaolin on concrete sulphuric acid resistance.
EmoTV 1 : Annotation of Real-life Emotions for the Specification of Multimodal Affective Interfaces

The development of future multimodal affective interfaces such as believable Embodied Conversational Agents requires to model relations between natural emotions and multimodal behaviors in various real-life contexts. Research should thus explore multimodal corpora and real-life databases (e.g. news, natural conversations). In order to collect reliable emotion annotations, one also needs to understand how people perceive emotional expressions in audio channels (vocal cues, content, and grammatical issues), and in visual channels (facial expressions, body movements, gaze, and spatial behavior). We designed EmoTV1, a corpus of video clips recorded from French TV channels containing interviews. In order to study the influence of the modalities on the perception of emotions, two annotators used the Anvil tool to annotate this corpus for three conditions: 1) audio without video, 2) video without audio, 3) video with audio. The annotators segmented the emotions perceived. Their classification resulted in a set of 14 labels: anger, despair, disgust, doubt, exaltation, fear, irritation, joy, neutral, pain, sadness, serenity, surprise and worry. The annotators also used two classical appraisal dimensions: intensity and valence (negative/positive emotion). Our work, described in this paper, lists the advantages and drawbacks of the corpus, describes how to gather a relevant corpus of video clips and define a scheme for annotating emotions. It also describes the possible annotation disagreements and the improvements that we intend to make after the analyses of this first annotation phase.
Shine a light ( on the bright ) : The effect of awards on confidence to speak up in gender-typed knowledge work

Collaborative knowledge work may suffer if high-ability individuals do not feel confident to speak up and advance their ideas (e.g., due to self-stereotyping). We test whether recognition through awards increases high-ability group members’ confidence to speak up when working on male-typed knowledge tasks. In a lab context where private feedback was ineffective, we study performancebased recognition with different degrees of publicness: private recognition, semi-public award, ceremony. We thus focus on managerial policies that are widely used in practice but have received limited scholarly attention. First, we show that self-stereotyping affects women’s contribution of ideas in mathematics. Second, awards significantly increase recipients' and hence high-ability subjects’ confidence to speak up. Third, the awards’ visibility does not matter much, except when interacted with gender. In our experiment the gender gap in confidence to speak up disappears among high-ability participants when awards are celebrated in a ceremony with face-to-face recognition. Losers remain unaffected.
Cyber-Physical Specification Mismatches 1 : 3 Cyber-Physical Models ( Simulink ) Instrument ( Hynger ) Execute / Simulate ( Simulink ) Infer Candidate Invariants ( Daikon

Embedded systems use increasingly complex software and are evolving into cyber-physical systems (CPS) with sophisticated interaction and coupling between physical and computational processes. Many CPS operate in safety-critical environments and have stringent certi cation, reliability, and correctness requirements. These systems undergo changes throughout their lifetimes, where either the software or physical hardware is updated in subsequent design iterations. One source of failure in safety-critical CPS is when there are unstated assumptions in either the physical or cyber parts of the system, and new components do not match those assumptions. In this work, we present an automated method towards identifying unstated assumptions in CPS. Dynamic speci cations in the form of candidate invariants of both the software and physical components are identi ed using dynamic analysis (executing and/or simulating the system implementation or model thereof). A prototype tool called Hynger (for HYbrid iNvariant GEneratoR) was developed that instruments Simulink/State ow (SLSF) model diagrams to generate traces in the input format compatible with the Daikon invariant inference tool, which has been extensively applied to software systems. Hynger, in conjunction with Daikon, is able to detect candidate invariants of several CPS case studies. We use the running example of a DC-to-DC power converter, and demonstrate that Hynger can detect a speci cation mismatch where a tolerance assumed by the software is violated due to a plant change. Another case study of a powertrain fuel control system is also introduced to illustrate the power of Hynger and Daikon in automatically identifying cyber-physical speci cation mismatches.
Mitochondrial DNA The Journal of DNA Mapping , Sequencing , and Analysis

Materials and methods: The present study is the first to apply DNA barcoding on identifying 37 freshwater fish species from the rich Balkan ichthyofauna. Results: The results are highly successful since in most cases barcodes cluster according to species, in agreement with morphological taxonomic studies. This is also evident based on mean conspecific and congeneric Kimura two-parameter distance values. The 5.6-fold difference between these values is lower than previous barcoding studies, possibly due to the restricted samplings and the recent taxonomy reevaluation for several species. A number of species were identified, where future work is needed: For the species Scardinius erythrophthalmus, Perca fluviatilis, and Rutilus rutilus, the divergence values found among conspecific populations could warrant their placement into different species; for Barbus and Rhodeus populations, the reported interspecific distances found were lower than expected; and for Cobitis species, the application of barcoding seems problematic, due to their complicated reproduction. Conclusion: The extension of this work to other Greek or even Balkan freshwater systems should clarify the situation.
Design Guidelines for Spherical Aerostatic Bearings

This work presents a detailed analytical and experimental analysis of spherical aerostatic bearings with multiple inlets and outlets. Presented are equations for load capacity, stiffness, flow rate, and pressure distribution for the bearings. It uses the Navier-Stokes equations in spherical coordinates while considering the air as a compressible fluid to obtain simple formulas for direct use by the designers. Experiments have been conducted by varying several parameters to validate the theoretical formulas developed for these precision machine elements. Introduction Spherical aerostatic bearings are useful in applications involving three rotational degrees of freedom such as satellite motion simulators or a robotic hand joint [1-5]. The main advantage of using these bearings is low stiction (starting friction), low rotational friction and high stiffness. The analytical theory developed for the design of spherical aerostatic bearings is complex and cumbersome to use for design engineers. Existing literature covers equations for design guidelines of aerostatic bearings such as circular, rectangular, cylindrical journal and thrust pad bearings, but little information is available for spherical aerostatic bearings [1-2]. The prediction of the pressure at the inlet of the socket is one of the most crucial and difficult steps in the analytical analysis of any aerostatic bearing [2]. In this work, the equation for the pressure at the inlet of the socket was derived and solved by considering air as a compressible fluid for spherical aerostatic bearing. The equations developed can be used for all types of spherical air bearings including fitted type (socket and ball are of same diameter), clearance type (socket and ball are of different diameter), single inlet and multiple inlets. Theory The bearing which was used for the experiments has the geometry as shown in Figure 1. This bearing is a multiple inlets spherical thrust pad bearing. The flow from the inlet is split into two, resulting in an upward (region 1) and downward flow (region 2). If the bearing shown in Figure 1 is displaced downwards, thereby reducing the thickness of the fluid film at the bottom of the bearing, the flow in region 1 is a diverging flow because the sectional area is increasing towards the exit of the flow (outlet at the upper edge of the bearing). The flow in region 2, on the other hand, is converging towards the outlet (bottom of the bearing). The equations were derived for the load capacity, stiffness and flow rate for this type of bearings using the references [1-4]. Figure 1: Spherical aerostatic thrust pad bearing. The total flow rate is [2],
Does it take two to tango ? IMF and World Bank cooperation : theory and empirical evidence

In this paper we present a theoretical model which, focusing on the quality of information transmission between the IMF and the WB, analyzes the sources of the expected loss in the overall performance of the two institutions relative to the rst best outcome characterized by centralized decision and perfect information. In particular, given the Bank-Fund strong complementarities, we show that strategic communication is indeed the primary source of loss for the two institutions. A testable implication of the model is to relate Bank-Funds performance to their willingness (or ability) to communicate. We nd evidence that a Bank-Fund simultaneous loan is associated to an increase in economic growth and, consistently with the theory, such e¤ect is diminished by factors preventing full communication, such as the degree of Bank-Fund competition and the salience of asymmetric information.
