Street's physical geometry and the cooling effect of waterbody of urban micro-climate in tropical region

The thesis addresses the contributions of urban geometry under tropical climate in the Melaka city, Malaysia and their benefits toward optimum cooling effect of water body modification. The aim is to examine quantitatively the potential of the cooling effect from combination of water bodies and street geometries with the development of comfortable microclimate conditions at street level in the city environment. Main methodologies phases which is field measurement were conducted and computer simulations were developed in order to achieve the aim and objectives of study. Environmental Visual Image Microclimate software (ENVI-met Ver. 4.0) was used to predict the impact of modification according to the proposed hypothetical urban geometries were simulated with various street aspect ratio (building’s height / street’s width) where the ratio is equal to 1, more than 1, and less than 1, and river width equal to 18, 36, and 54 meters. The proposed urban settings in Melaka city that resulted from the combination of the various streets and river width were modelled on four different orientations, North-South, East-West, Northeast-Southwest and Northwest-Southeast, while a total of 36 different urban geometries were evaluated. The model was successfully validated through the correlation of measured experiments and computer simulation which reliable enough to present the actual urban microclimate condition of Melaka river area. The outdoor thermal comfort was assessed based on the Physiological Equivalent Temperature (PET) as reference to evaluate modification benefits towards outdoor comfort level. It is revealed that the existing variation in temperature between the different urban locations in the Melaka river area was due to the influence of their street geometrical characteristics. Overall, the improvements of thermal comfort via the addition of water bodies is very minimal when compared to the improvements brought by aspect ratios. The highly humid climate in Malaysia and the low wind speed conditions is the reason for this occurrence. The conclusions point out besides the necessity of street geometry, water body cooling effects can be implemented as additional guide lines in urban design to keep the external microclimate conditions in comfort range.
Relating Phytoplankton Pnysiology to North Pacific Biogeo- chemistry

Dynamics of nutrient ratios Consistent with findings from previous laboratory experiments examining the effect of iron fertilization on phytoplankton (Hutchins and Bruland 1998; Franck et al. 2000), the ratio of Si to N drawdown increased at the return of iron limitation (after iron addition and its subsequent depletion) during the approximately two-week period of the SERIES field experiment (Boyd et al. 2004, 2005; Takeda et al. 2006). In the laboratory experiments, this increase in Si:N drawdown ratio resulted mostly from a decrease in the rate of N uptake. In contrast, during SERIES, the rate of N uptake actually increased (Boyd et al. 2005), and the rate of Si uptake increased by an even greater factor, so that the Si:N ratio increased. This suggested that a different mechanism could have caused the change in uptake ratio during Relating Phytoplankton Pnysiology to North Pacific Biogeochemistry

Chemical and Metabolic Pathway Semantic Similarity

Background: Similarity measures for the comparison of metabolic pathways can provide a better understanding of evolutionary relationships among species or strains and have an important biotechnological value for the pharmaceutical industry. Semantic similarity applied to enzymes has been used; here we show an approach using metabolites. While there is a number of methods to compare and align metabolic pathways based on metabolites, they are usually based only on their structural information neglecting their biological information. Results: In this work we present an alternative approach for measuring the semantic similarity between metabolic pathways by comparing their metabolites. This comparison is based on the Chemical Entities of Biological Interest ontology, and can be useful in toxicology and drug discovery for assessment of biological activity of chemical compounds. We implemented a software capable of measuring the similarity between metabolic pathways present in the Kyoto Encyclopedia of Genes and Genomes database and a preliminary analysis shows the effectiveness of the proposed approach. Conclusions: We have shown that semantic similarity can be applied to pathways whose chemical compounds are annotated in the Chemical Entities of Biological Interest ontology. This work resulted in the creation of a software, CMPSim, accessible as a web-tool at http://xldb.di. fc. ul.pt/biotools/cmpsim/. It can be used to obtain similarity measures between chemical compounds and metabolic pathways.
OPTICAL DISTURBANCES CAUSED BY TRANSONIC SEPARATED BOUNDARY LAYER BEHIND A 20-DEGREE RAMP: PHYSICS AND CONTROL.

In a previous paper [1], we documented the optical disturbance environment created by an attached turbulent boundary layer in high-Mach-number subsonic flow. In the earlier paper, an opticalaberration measurement instrument, the Malley probe, was described and used to collect a high-resolution time series of the optical aberrations for the boundary layer. In the present paper, results using the same instrument will be presented for a high-subsonic, turbulent boundary layer passing a downward 20 degree ramp. In this case, the flow becomes globally separated; the optical aberration environment upon separation starts at the level associated with the turbulent boundary layer but rapidly grows to a much higher level than for the upstream, attached boundary layer. Streamwise and spanwise measurements of Optical Path Difference (OPD) and local convective speeds of the opticallysignificant structures along the ramp were performed, along with velocity profiles. The objective of the work was to explore the use of passive devices to reduce the aberration environment created by the separating shear layer. A variety of

Relationship between Baseline White Blood Cell and C-Reactive Protein with Mortality in Patients with Spontaneous Intracerebral Hemorrhage

Background: Inflammation has been shown to play a role in animal models of intracerebral hemorrhage, but actually its role in predicting outcome in spontaneous intracerebral hemorrhage (sICH) is not clear because of the lack of evidence. This study was designed to determine the relationship between baseline white blood cell (WBC) count and clinical outcomes in patients with sICH and to see if WBC count was a significant predictor of outcomes independent of other in fl ammatory biomarkers such as C-reactive protein (CRP) a well de fi ned prognostic marker in ischemic stroke. Methods: We evaluated the relationship between baseline WBC count, other baseline variables and biomarkers, neuroradiological fi ndings, and clinical outcomes in 175 consecutive patients with a well-de fi ned diagnosis of sICH admitted into 24 hours in 3 primary referred centers and included in a prospective observational follow-up registry . Results: Higher baseline wbc counts were associated with hematoma volume at admission (p<0.0001) as well as a greater sich severity (p=0.0016) assessed by glasgow coma scale. a higher baseline wbc count was predictive of higher 30-day mortality, ranging from 10.42% among patients with the lowest wbc count quartile to 66.7 among patients with he highest wbc count quartile (p=<0.0001, χ 2 for trend). however, in a multivariable proportional hazards model, wbc count was unable to con fi rm its predictive prognostic value when adjusted for possible confounding variables and crp concentration quartiles [hazards ratios (hr) 1.23 95% con fi dence intervals (ci) 0.41-3.68, p=0.7079] while patients with the highest crp concentrations at admission showed a significantly higher risk of 30-day death (hr 2.83, 95%ci 1.14-7.05, p=0.0254) although, crp levels were only lightly associated with stroke severity (p=0.0747). Conclusions: In patients with sICH, the WBC count was associated with 30-day high mortality rates although, this association reversed when other confounding variables were taken in account suggesting only a role of surrogate biomarker of sICH severity. CRP concentrations appeared more effective in predicting prognosis although its predictive power is limited.

Assessment of Groundwater Quality for Drinking Purposes Using Water Quality Index (WQI) in Shiraz, Iran (2011 to 2015)

Drinking water quality monitoring is a prerequisite for macro planning of development programs in metropolitans, improvement in health, and water resources management. Since WQIs (Water Quality Index) are known as comprehensive tools for interpretation of water quality, this study benefitted from this tool to determine the drinking water quality trends in Shiraz, Iran in a five year period from 2011 to 2015 and figure out the factors affecting its changes in this city. For this aim, annual data of 9 water quality parameters including DO, Fecal Coliforms, pH, BOD5, NO3, PO4, temperature deviation, turbidity, and TS were collected for 45 drinking water wells located in 4 zones (Dokuhak, Derak, Sabzpushan, and Chamran) to calculate the WQI. Pairwise comparison of years in terms of WQI values was analyzed statically using post-HOC analysis in Univariable repeated measure test. The results showed that the highest and the lowest water quality level both for annual and long term evaluations belonged to Derak and Chamran zones, respectively. All the studied wells in the five years were classified in "good" quality group. According to statistically analyze the highest significant change in water quality (p-value < 0.001) was found between the two years 2013 and 2015. In terminal years of the study, the increased concentration of TS and NO3 caused a partial decrease in water quality in some sources. These significant differences can be considered as a warning for the soon future. Therefore, it makes sense to accelerate the development of sewer systems and manage uncontrolled population growth in this city to prevent further water pollution. Permanent monitoring of water quality using WQIs seems to be essential to figure out a perspective of water quality trends and proper decision-making for developments in urban areas.
Validation of 10-year SAO OMI ozone profile (PROFOZ) product using Aura MLS measurements

Abstract. We validate the Ozone Monitoring Instrument (OMI) ozone profile (PROFOZ v0.9.3) product including ozone profiles between 0.22 and 261 hPa and stratospheric ozone columns (SOCs) down to 100, 215, and 261 hPa from October 2004 through December 2014 retrieved by the Smithsonian Astrophysical Observatory (SAO) algorithm against the latest Microwave Limb Sound (MLS) v4.2x data. We also evaluate the effects of OMI row anomaly (RA) on the retrieval by dividing the data set into before and after the occurrence of serious RA, i.e., pre-RA (2004–2008) and post-RA (2009–2014). During the pre-RA period, OMI ozone profiles agree very well with MLS data. After applying OMI averaging kernels to MLS data, the global mean biases (MBs) are within 3 % between 0.22 and 100 hPa, negative biases are within 3–9 % for lower layers, and the standard deviations (SDs) are 3.5–5 % from 1 to 40 hPa, 6–10 % for upper layers, and 5–20 % for lower layers. OMI shows biases dependent on latitude and solar zenith angle (SZA), but MBs and SDs are mostly within 10 % except for low and high altitudes of high latitudes and SZAs. Compared to the retrievals during the pre-RA period, OMI retrievals during the post-RA period degrade slightly between 5 and 261 hPa with MBs and SDs typically larger by 2–5 %, and degrade much more for pressure less than ∼ 5 hPa, with larger MBs by up to 8 % and SDs by up to 15 %, where the MBs are larger by 10–15 % south of 40 ∘ N due to the blockage effect of RA and smaller by 15–20 % north of 40 ∘ N due to the solar contamination effect of RA. The much worse comparisons at high altitudes indicate the UV1 channel of pixels that are not flagged as RA is still affected by the RA. During the pre-RA period, OMI SOCs show very good agreement with MLS data with global mean MBs within 0.6 % and SDs of 1.9 % for SOCs down to 215 and 261 hPa and of 2.30 % for SOC down to 100 hPa. Despite clearly worse ozone profile comparisons during the post-RA period, OMI SOCs only slightly degrade, with SDs larger by 0.4–0.6 % mostly due to looser spatial coincidence criteria as a result of missing data from RA and MBs larger by 0.4–0.7 %. Our retrieval comparisons indicate significant bias trends, especially during the post-RA period. The spatiotemporal variation of our retrieval performance suggests the need to improve OMI's radiometric calibration to maintain the long-term stability and spatial consistency of the PROFOZ product.
Combination of simvastatin and hydroxyapatite fiber induces bone augmentation

This study evaluated the capability of hydroxyapatite fiber (HAF) as a carrier and the bone formation by blending simvastatin. The mixture of HAF and simvastatin (0.15, 0.45, 0.75 mg) was placed in 1 ml of tris-buffer and the release of simvastatin from HAF was calculated per 24 hours for 10 days. Bilateral 5 mm-diameter and 3 mm-hight Teflon chambers were fixed on calvaria of adult Japanese white rabbits and filled with 40 mg HAF which containing simvastatin (0, 0.15, 0.45, 0.75 mg). The animals were sacrificed at 4 and 8 weeks and calculated radiologically by Micro-CT. After dyeing by toluidine blue the samples were analyzed histologically. In all of the study groups approximately 25% of simvastatin was released until 10 days. The new bone volume ratio measured by Micro-CT of 4 and 8 weeks group was (22.4%, 21.3%, 41.6%, 26.3%) and (20.2%, 11.7%, 42.1%, 31.2%) in different doses respectively. The 0.45 mg group showed significantly higher new bone volume ratio than 0 mg group and 0.15 mg group. The histological measurement and observations also supported these results. In conclusion, the HAF could be used as a carrier for simvastatin. Combinations of HAF and simvastatin have the potentiality to stimulate new bone formation and approximately 0.45 mg simvastatin in 40 mg HAF is the optimal dose in rabbit chamber model.
Study of Spectral Efficiency for LTE Network

The efficiency with which spectrum is used in wireless communication systems is becoming increasingly important as a result of rapidly growing demands for bandwidth-intensive mobile broadband services and the finite nature of usable spectrum. Faced with ever-increasing cost pressures, it is significant for mobile network operator to make the most of spectrum investments. Therefore, this paper serves audience to better understand spectral efficiency, the factors that influence the efficient use of spectrum, the ways of measuring it and finally, what can be done to improve this wireless network performance metric.
Factors underlying cognitive giftedness: Mental versus perceptual attention

Children identified as cognitively gifted, in comparison with age-matched mainstream samples, are advantaged in numerous areas, including mathematics, speed and efficiency in cognitive processing, and resistance to interfering stimuli. Although working memory (WM) has been implicated as a factor mediating these advantages, evidence suggests that gifted children may not be advantaged in all aspects of WM function. We hypothesized that this difference is related to the contrast between mental (related to prefrontal dopamine circuits) and perceptual attention (likely related to prefrontal acetylcholine circuits). Specifically, it was expected that cognitively gifted children would excel in WM tasks taxing mental but not perceptual attention. Ninety-one children from grades 4 and 8, in the gifted and mainstream academic streams, received WM tasks requiring primarily perceptual attention (SOPT) and mental attention (n-back), as well as measures of mental-attentional capacity, shifting, and inhibition. Gifted children outperformed their mainstream peers on all tasks, except SOPT (even when mental demand was matched). Results demonstrate a necessary distinction between mental and perceptual attention in the measurement of WM.
Seepage Characteristics Study on Power-Law Fluid in Fractal Porous Media

We present fractal models for the flow rate, velocity, effective viscosity, apparent viscosity, and effective permeability for power-law fluid based on the fractal properties of porous media. The proposed expressions realize the quantitative description to the relation between the properties of the power-law fluid and the parameters of the microstructure of the porous media. The model predictions are compared with related data and good agreement between them is found. The analytical expressions will contribute to the revealing of physical principles for the power-law fluid flow in porous media.
Metallicity effects on classical Cepheids: Velocity curve morphology of outer disc Cepheids

We present new radial velocity data for eleven classical Cepheids situated in the outer parts of the Galactic disc. The resultant velocity curves for these metal-deficient Cepheids are decomposed in Fourier parameters, and compared to solar-metallicity Cepheid data, in order to study the effect of metallicity on the pulsation properties. Up to $P\simeq$ 8 days, the $\phi_{21}$ phase shift is found to follow very closely the corresponding sequence for solar-metallicity Cepheids, indicating the absence of metallicity effects on $\phi_{21}$ for low periods. However, metal-deficient Cepheids show a slightly larger A 1 amplitude and R 21 amplitude ratio for $P 12$ days, there is some evidence that the $\phi_{21}$ phase shift is significantly larger for metal-deficient Cepheids than at solar metallicity. A posteriori, this effect is also detected in photometric data for outer disc and LMC Cepheids in the 12-20 day period range. In good qualitative agreement with the predictions of theoretical pulsation models, we therefore see some indication of a metallicity dependence of the $P_2/P_0$ resonance properties. The largest effects on velocity curve shape are expected in the crucial 8-12 day period range -around the $P_{2}/P_{0}$ resonance for fundamental-mode Cepheids -that is not covered by our data. Possible targets for future measurements are suggested to fill this gap, and to improve the quantitative determination of metallicity effects on the structural properties of Cepheid velocity curves.
MOIM: a novel design of cryptographic hash function

A hash function usually has two main components: a compression function or permutation function and mode of operation. In this paper, we propose a new concrete novel design of a permutation based hash functions called MOIM. MOIM is based on concatenating two parallel fast wide pipe constructions as a mode of operation designed by Nandi and Paul, and presented at Indocrypt 2010 where the size of the internal state is significantly larger than the size of the output. And the permutations functions used in MOIM are inspired from the SHA-3 finalist Grostl hash function which is originally inspired from Rijndael design (AES). As a consequence there is a very strong confusion and diffusion in MOIM. Also, we show that MOIM resists all the generic attacks and Joux attack in two defense security levels.

Relation modules for finite W-algebras and tensor products of highest weight evaluation modules for Yangians of type A

We construct explicitly a large family of Gelfand-Tsetlin modules for an arbitrary finite W-algebra of type A and establish their irreducibility. A basis of these modules is formed by the Gelfand-Tsetlin tableaux whose entries satisfy certain admissible sets of relations. Characterization and an effective method of constructing such admissible relations are given. In the case of the Yangian of gl_n we prove the sufficient condition for the irreducibility of the tensor product of two highest weight relation modules and establish irreducibility of any number of highest weight relation modules with generic highest weights. This extends the results of Molev to infinite dimensional highest modules.
