Estimating duster compactness in Yaghouti grapes

Cluster compactness of Yaghouti grapes was defined and measured as the percentage of the total volume occupied by the solid volume. The total volume is the solid volume plus the space between the berries. This measure of compactness was used to judge the suitability of other means of estimating compactness. It is concluded that the ratio of the solid volume to the total length of the rachis plus that of its primary laterals is the most suitable estimator of compactness. Beurteilung der Beerendichte bei der Rebsorte Jagbouti Die Beerendichte der Jaghouti-Trauben wurde als der prozentuale Anteil des Festvolumens am Gesamtvolumen der Traube definiert und gemessen. Das Gesamtvolumen ist das Festvolumen (Beeren mit Traubengerust) und der Zwischenraum zwischen den Weinbeeren. Dieses Mas der Beerendichte wurde dazu verwendet, um die Brauchbarkeit anderer Methoden zur Schatzung der Beerendichte zu beurteilen. Es wurde festgestellt, das sich der Quotient aus Festvolumen und Gesamtlange der Traubenachse und der Seitenaste 1. Ordnung fur die Schatzung der Beerendichte am besten eignet.
Evidence of Petroleum Resources on Nigerian Economic Development

The Study was an Examination of the impact of Petroleum on Nigerian Economy. The sector has been the main source of foreign reserve and development capital for the country. Yet little or nothing is been done to support the sector. The study was based on secondary data. Data was sourced from the Central Bank of Nigeria Statistical Bulletin and National Bureau of Statistics. The data used was a ten years record of GDP and Oil Revenue i.e., 2000-2009. Findings show that petroleum has significant and positive impact on Nigeria economy. The researchers therefore recommend that the sector should be supported so that the country can derive the full benefits of the sector .

A seismic refraction study of the crustal structure associated with the Adamawa Plateau and Garoua Rift, Cameroon, West Africa

Summary Recordings of quarry blasts along a 300 km profile across the Adamawa Plateau at the eastern end of the Cameroon Volcanic Line permitted the determination of the crustal structure of the region. To the north of the Plateau in the area of the Garoua Rift, an eastern arm of Benue Trough the crust is about 23 km thick and is underlain by upper mantle with a P-wave velocity of 7.8 kms-1. The southern part of the Plateau by comparison is associated with a more normal crustal thickness of about 33 km and underlain by upper mantle with a velocity of 8.0 kms-1. Between these two areas the seismological experiment was not able to delineate how the crust changes. However, if the topography and gravity field reflect crustal thickness then there is a rapid change in crustal thickness at the northern edge of the Adamawa Plateau. The study thus provides the first seismic evidence for major crustal thinning beneath the Garoua arm of the West African Rift System as well as providing evidence for an alternative model for the formation of the Cameroon Volcanic Line.
Day-ahead Pricing Model for Smart Cloud using Time Dependent Pricing

Smart clouds allow every consumer and cloud service provider a two-way communication, thus enabling cloud service provider to generate a time dependent pricing model using a feedback loop. This model charges a consumer more in peak periods and less during off peak periods, which encourages consumers to reschedule their workload to less traffic (off-peak) periods. This helps service providers to practice a versatile pricing technique to increase their profits by covering off-peak demand and minimizing the provider"s cost optimization problem. It also minimizes the execution time in setting these prices by Compromised Cost-Time Based (CCTB) scheduling. Shifting workload is a probabilistic function which tells consumers to shift their workload. This paper presents a model to calculate day-ahead prices. The proposed model dynamically adjusts the rewards or discounts based on consumer behavior in the past, and helps providers to maximize their revenue by shifting the consumers" workload.
Radar remote sensing technologies: The usage in agriculture

This paper presents the active remote sensing technology, based on the use of electromagnetic waves from the microwave frequency range. According to sensor distance from the surface soil layer, two existing radar technologies were analyzed: Synthetic Aperture Radar (SAR) and Ground Penetrating Radar technology (GPR). Considering the fact that the SAR antenna is designed for satellite platforms, the application of this technology in agriculture includes the procedures of classification of arable land and crops, in unfavorable situations. From the point of the usage of GPR technology, where the antenna is close to, or in contact with the surface layer, the application is based on the analysis of both geometric and general characteristics of underground soil layers to a depth of 10m. Using a comparative analysis of both technologies, a common area of application in the form of complex, composite technologies is defined.
The Role of Parental Cognitive Aging in the Intergenerational Mobility of Cognitive Abilities

This paper studies intergenerational transmission of cognitive abilities from parents to children, highlighting the role of parental cognitive ageing measured during adulthood, net of their cognitive abilities measured in adolescence. We investigate the life-cycle of parental cognitive abilities on offspring’s cognitive abilities within the British National Child Development Study (NCDS). We find that children benefit not only from the stock of cognitive abilities their mothers and fathers hold as adolescents, but also from cognitive evolution their parents achieve as adults. Furthermore, we find that favourable parental cognitive ageing is particularly important for low ability offspring, pointing to a potential role of cognition in delivering more effective mitigation and nurturing. When analysing three subsequent generations, we find that the transmission of late parental cognition is strong in the offspring with high education origins, in particular for the those in the upper tail of the cognitive abilities distribution. We quantify the economic impact of the cognitive ageing transmission, and find that one standard deviation increase in late parental cognition can be approximated to an average of 1.7% increase in offspring earnings.
Using Learning Analytic Tools to Enhance Quality of Hands-on-Activities in Online Technology Courses

In the last few years, there has been a proliferation of online Information Technology (IT) and management related programs in many Thai universities. Big data analytic has turned into a new science in refining businesses strategies, but there is a lack of strategy when it comes to analyzing the data captured in various Learning Management Systems (LMSs) used for hosting the course contents. This case study provides an insight into how to use of Moodle “Reports” as a Learning Analytic (LA) tool for analyzing the use of Hands-on-Activities (HOAs), lab activities and assignments provided in technology related courses. This small study is also used to propose a new framework for using LA to improve quality assurance (QA) in such programs.
BACTERIAL BIOAEROSOLS IN THE OPERATING ROOMS: A CASE STUDY IN TEHRAN SHARIATI HOSPITAL

Introduction : Maintenance of adequate hospital indoor air quality (HIAQ) in operating rooms (ORs) is critical to the Surgical Site Infection (SSI) in hospitalized patients. This study assessed the concentration of bacterial bioaerosols in various ORs in a hospital. Materials and methods: The concentration of bacterial bioaerosols was measured in the 8 ORs and 2 nurse stations. Active sampling method was used to monitor bacterial bioaerosols. Results: The mean concentrations of the total bacteria were 211-386 and 208-443 CFU/ m3 in the first and second floor, respectively. Gram-positive bacteria (e.g., Micrococcus spp., Staphylococcus spp. and streptococcus spp.) were frequently observed in the assessed ORs and nurse stations. Conclusions : Bacterial bioaerosol monitoring is a useful tool for evaluation of the bio-contamination of ORs in order to improve indoor air quality of them.
Instantaneous optimal investment decisions with costly and costless reversibility

En general, las diferentes teorias que se han planteado para explicar la inversion se basan en problemas de optimizacion dinamica cuyas soluciones cuentan con diferentes metodos. En dichos modelos, los valores optimos de las variables de control y de estado, etiquetadas como inversion y capital respectivamente, dependen de los precios futuros del producto y de los factores de la produccion y del nivel de capital al final del periodo. En este articulo sugerimos un nuevo metodo para obtener los niveles optimos de inversion sin requerir informacion sobre los precios futuros o las condiciones de transversalidad. Asi, en lugar de maximizar el valor presente de los flujos de caja por unidad de capital, como un indice de desempeno, la empresa maximiza el valor actual del flujo de caja por unidad de capital.
Number filter for matter waves

In current Bose-Einstein condensate experiments, the shot-to-shot variation of the atom number fluctuates up to 10%. In here, we present a procedure to suppress such fluctuations by using a nonlinear $p\ensuremath{-}\ensuremath{\pi}\ensuremath{-}\overline{p}$ matter wave interferometer for a Bose-Einstein condensate with two internal states and a high beam-splitter asymmetry $(p\ensuremath{\ne}0.5)$. We analyze the situation for an inhomogeneous trap within the Gross-Pitaevskii mean-field theory, as well as a quantum mechanical Josephson model, which addresses complementary aspects of the problem and agrees well otherwise.
Phenological trends among Australian alpine species: using herbarium records to identify climate-change indicators.

In the present paper, we explore the limitations and strengthsofusingherbariumspecimenstodetectchangesin floweringphenology,toselectpotentialindicatorspecies,andto pinpoint locations for potential monitoring schemes of native plants in Australia's subalpine and alpine zone.

By the use of gridded temperature data within the study region, we identifiedanincreaseinmeanannualtemperatureof0.74 � Cbetween1950and2007.Wethenmatchedthespatiallocationsof the herbarium specimens to these temperature data and, by using linear regression models, identified five species whose flowering response may be sensitive to temperature.

Flexible metamaterials at visible frequencies and applications

We discuss our recent results regarding the realization and characterization of metamaterials on flexible substrates at visible wavelengths (Metaflex). We outline the fabrication procedure and show the electromagnetic response for different plasmonic structures. We also report on the verification of Fano resonances on Metaflex, which yields to ultra-narrow spectral features in flexible plasmonic surfaces, and on the realization of a flexible metamaterial with response independent on polarization and angle of incidence.
A Recursive Formula for the Reliability of a r-Uniform Complete Hypergraph and Its Applications

The reliability polynomial R(S,p) of a finite graph or hypergraph S=(V,E) gives the probability that the operational edges or hyperedges of S induce a connected spanning subgraph or subhypergraph, respectively, assuming that all (hyper)edges of S fail independently with an identical probability q=1-p. In this paper, we investigate the probability that the hyperedges of a hypergraph with randomly failing hyperedges induce a connected spanning subhypergraph. The computation of the reliability for (hyper)graphs is an NP-hard problem. We provide recurrence relations for the reliability of r-uniform complete hypergraphs with hyperedge failure. Consequently, we determine and calculate the number of connected spanning subhypergraphs with given size in the r-uniform complete hypergraphs.
A Comparison between Low and High-dose of Hydroxyethylstarch Solution in Resuscitation for Shock induced by Ischemia/Reperfusion in Rabbits

The purpose of the study was to compare the effects of high and low dose of 6% hydroxyethyl starch solution (HES) on resuscitation for shock induced by intestinal ischemia/reperfusion (I/R) injury in rabbits. Thirty-two anesthetized rabbits were randomized into four groups of eight animals each, which was either treated with no fluid resuscitation as control, lactated Ringer’s solution (LRS, 20ml/kg/h), LRS+HES (LRS 18ml/kg/h + HES 2ml/kg/h, low dose of HES) or only treated with HES (high dose of HES, 20ml/kg/h). These rabbits underwent the intestinal I/R injury developed by occluding superior mesenteric artery (SMA) with a noncrushing vascular clamp for 60min and then loosing the clamp for 240min. The fluid resuscitation began at the same time of reperfusion. Hemodynamic parameters including MAP, HR, aortic velocity (Qaorta, as CO) and SMA blood flow (Osma) were measured. Tissue oxygenation was assessed indirectly by measuring the tonometric parameters of gut, including difference between intestinal intramucosal PtCO2 and arterial PaCO2 (PCO2-gap), intestinal intramucosal pH (pHi), arterial lactate acid concentration and oxygen delivery (DO2). Mortality of the rabbits was calculated at the end. The results showed that hemodynamic parameters were significantly higher in group LRS+HES and HES than in group LRS and control (P<0.05). Low dose of HES was better than high dose of HES in restoring hemodynamic parameters (P<0.05). Low dose of HES could greatly decrease lactate and PCO2-gap, significantly improve pHi than other three groups (P<0.05), but high dose of HES did not do so, rather, which induced oral and nasal bleeding, even death of some animals. Low dose and high dose of HES significantly improved DO2 while LRS did not (P<0.05). Therefore low dose of HSE together with LRS was more effective than only high dose of HES or LRS in the resuscitation for shock induced by intestinal I/R injury in rabbits, because hemodynamic parameters increased suitably and tissue oxygenation was greatly improved.

Effectiveness of the Group-Based Positive Parenting Program with Japanese Families Raising a Child with Developmental Disabilities: A Longitudinal Study

This study aims to investigate the effectiveness of a group-based family intervention program known as the Positive Parenting Program (Triple P) with families raising a child with developmental disabilities in Japan. Reductions in children’s behavioral problems, changes in dysfunctional parenting practices, and promoting effects on family empowerment were examined. Participants (N=54) were recruited from mothers visiting two hospitals and two parental groups in the Tokyo metropolitan area. They were assessed in terms of child behavior (Strengths and Difficulties Questionnaire), parenting style (Parenting Scale), parenting adjustment (Depression Anxiety Stress Scale and Parenting Experience Survey), and family empowerment (Family Empowerment Scale). All outcomes were measured repeatedly from pre-intervention to six months after intervention. The Strengths and Difficulties Questionnaire scores for three sub scales emotional symptoms conduct problems, and difficult behavior indicated a significant intervention effect in the children. Moreover, the Parenting Scale scores for all subscales, the Depression Anxiety Stress Scale scores for all subscales, and the Parenting Experience Survey scores for the subscales except for the fulfilling subscale, the perception of agreement with partner regarding child discipline subscale, and the perception of support received from partner subscale, indicated a significant intervention effect in the caregivers. In addition, the Family Empowerment Scale scores for all subscales indicated a significant intervention effect in the family. These results provided promising evidence for the group intervention based Triple Pas an effective intervention program for Japanese families raising preschool and school-aged children with developmental disabilities.

E-mail: onarantes@gmail.com. Resumo DOI: 10.5433/1679-0367.2012v33n2p161 Bacillus thuringiensis is a Gram-positive spore-forming bacterium that produces a parasporal crystal toxic for many insects. The aim of this study was the development of a low-cost medium for the culture of B. thuringiensis subsp. israelensis HD 537 to be used in a local insect control program in Brazil. In this study, the evaluated parameters were bacterial growth and toxicity of the cultures against Aedes aegypti larvae. The first strategy analised was the effect of salts, glucose, and yeast hydrolizate concentrations in a modified Arcas medium. The maximum toxicity in the bioassays (LC50 2.31 mg.l-1) were obtained by using a medium showing the highest tested concentrations of nitrogen sources and salts (8.00 e 0.47 g.l-1, respectively). In the second strategy was used a medium based in a ground Bombyx mori pupae. The maximum toxicity (LC 50 3.64 mg.l -1) was obtained with Bm 100 medium, with 100 g.l-1 of ground B. mori pupae. Beyond of the significant media differences in LC50 values, Bm100 medium was 120 times less expensive than the best Arcas modified medium. Thus, these results confirm the viability of ground B. mori pupae for B. thuringiensis subsp. israelensis growth and crystal production.
Interactive comment on “Evaluating the hydrological consistency of satellite based water cycle components” by O. López et al

Comment 1. The study focuses on four "relatively simple" catchments. But what’s so simple about these catchments? The runoff fraction is definitely not negligible (see Figure 2). The snowfall fraction in some of them is quite high (e.g., precipitation in the Aral Sea and Colorado catchments is composed of about 15% snowfall). The Niger catchment and maybe others have extensive wetlands which store and evaporate large amounts of water. Some of the catchments (e.g., the Colorado one) are also littered with reservoirs. All these factors contribute considerably to the total water storage and thus should be explicitly accounted for in such a study (as recognized by the authors
