Dynamics of rising bubble inside a viscosity-stratified medium

The rising bubble dynamics in an unconfined quiescent viscosity-stratified medium has been numerically investigated. This is frequently encountered in industrial as well as natural phenomena. In spite of the large number of studies carried out on bubbles and drops, very few studies have examined the influence of viscosity stratification on bubble rise dynamics. To the best of our knowledge, none of them have isolated the effects of viscosity-stratification alone, even though it is known to influence the dynamics extensively, which is the main objective of the present study. By conducting time-dependent simulations, we present a library of bubble shapes in the Galilei and the Eotvos numbers plane. Our results demonstrate some counter-intuitive phenomena for certain range of parameters due to the presence of viscosity stratification in the surrounding fluid. We found that in a linearly increasing viscosity medium, for certain values of parameters, bubble undergoes large deformation by forming an elongated s.
A Comparison of a New Prototype Tickle Talker™ w.ith the Tactaid 7

This study compared the speech perception enhance­ ment provided by two multichannel tactile aids: a new version of the Tickle Talker T'" and the Tactaid 7. The subjects' impression of benefit was also examined. In an AB pattern, six adults with hearing impairment used each device daily for approximately 18 weeks and attended 12 training sessions. When tactile information was provided, the group demon­ strated a significant enhancement for the perception of words (mean 17.2%) and phonemes (mean 12.9%) in monosyllabic word lists, words in sentences (mean 14.2%) and speechtracking (mean 7.7 wpm). The Tactaid 7 provided a significantly greater enhance­ ment for the perception of words (21 % versus 13.4%), phonemes (16.7% versus 9.1%) and some speech features in monosyllabic word lists. Subjective ratings were slightly higher for the Tactaid 7, and four subjects preferred this device. Either device may be suitable for those not able or willing to have a cochlear implant.
Osteochondral defect repair using a polyvinyl alcoholpolyacrylic alcoholpolyacrylic alcoholpolyacrylic acid ( PVAPAAc PVAPAAc PVAPAAc ) hydrogel

Poly(vinyl alcohol) (PVA) hydrogels can be candidates for articular cartilage repair due to their high water content. We synthesized a PVA-poly(acrylic acid) (PAAc) hydrogel formulation and determined its ability to function as a treatment option for condylar osteochondral (OC) defects in a New Zealand white rabbit (NZWR) model for 12 weeks and 24 weeks. In addition to hydrogel OC implants, tensile bar-shaped hydrogels were also implanted subcutaneously to evaluate changes in mechanical properties as a function of in vivo duration. There were no statistically significant differences (p > 0.05) in the water content measured in the OC hydrogel implant that was harvested after 12 weeks and 24 weeks, and non-implanted controls. There were no statistically significant differences (p > 0.05) in the break stress, strain at break or modulus of the tensile bars either between groups. Histological analysis of the OC defect, synovial capsule and fibrous tissue around the tensile bars determined hydrogel biocompatibility. Twelve-week hydrogels were found to be in situ flush with the articular cartilage; meniscal tissue demonstrated an intact surface. Twenty-four week hydrogels protruded from the defect site due to lack of integration with subchondral tissue, causing fibrillation to the meniscal surface. Condylar micro-CT scans ruled out osteolysis and bone cysts of the subchondral bone, and no PVA-PAAc hydrogel contents were found in the synovial fluid. The PVA-PAAc hydrogel was determined to be fully biocompatible, maintained its properties over time, and performed well at the 12 week time point. Physical fixation of the PVA-PAAc hydrogel to the subchondral bone is required to ensure long-term performance of hydrogel plugs for OC defect repair.
Eastward electric field enhancement and geomagnetic positive bay in the dayside low‐latitude ionosphere caused by magnetospheric substorms during sawtooth events

Substorms cause significant disturbances in the magnetosphere and ionosphere. Although many substorm‐induced phenomena have been relatively well understood, a serious controversy arises as to how the magnetospheric and ionospheric convection responds to the expansion onset. In this paper, we present the observations of the low‐latitude ionospheric electric field and geomagnetic field at substorm onsets during sawtooth events when the interplanetary magnetic field (IMF) remains steady southward, so the ionospheric disturbances are attributed solely to the substorm effects. In the substorm events we have analyzed, the dayside equatorial ionospheric electric field shows an eastward enhancement at the onset, and the geomagnetic field northward component at middle and low latitudes shows an increase (positive bay) on both the dayside and nightside. We suggest that the magnetospheric convection is enhanced at substorm onset and that the enhanced magnetospheric convection electric field penetrates to the low‐latitude ionosphere. The penetration electric field driven by substorm onset causes the eastward ionospheric electric field enhancement and geomagnetic positive bay on the dayside, and the substorm current wedge causes the geomagnetic positive bay on the nightside. Our findings are significantly different from the results of most previous studies and provide new insight into the substorm dynamic process.
Molecular marker (AFLP)-based Manihot and cassava numerical taxonomy and genetic structure analysis in progress : implications for their dynamic conservation and genetic mapping

Resume We are using multilocus molecular markers, with samples representing the geographic and ecological range of distribution of Manibotspp. , along with classical botany and ecology, to characterize: 1) the genetic structure of cassava in relation to its wild relatives and 2) the domestication process of cassava. Not only a numerical taxonomy of the genus is expected but also the definition of strategies for the conservation and the utilization of these genetic resources. Amplification fragment length polymorphism (AFLPTM) is used on: 1) 276 plants representing a large part of the diversity of the wild species of the genus, and some presumed natural inter-specific hybrids, and 2) 82 plants of cassava representing a) the cultivars in the world collections, and b) the varieties present in one Amazonian field with ethnobotanical record. The two first axis of variation (PCo of the matrix of similarity in pair-wise comparisons) extract, from the total, cassava along with several species that are closely related to it, including hybrids between M. glazovii and cassava. Although domestication appears to have involved primarily M. esculenta spp. flabellifolia and peruviana, it seems that some other species have also contributed. The question of the possible role of inter-specific hybridization in the domestication process of cassava is then raised again, particularly since the importance of inter-specific hybridization and also the high ratio of intrdinter-specific variation in the genus are confirmed. The genetic diversity of cassava itself is high, but a diversity nearly equal, although slightly divergent, is found in a single Amazonian field at the level of AFLP. It is shown that a traditional varietycan include several related genotypes and the hypothesis of a dynamic management of the diversity of cassava according to the Amzonian tradition is confirmed. The results validate the methodology adopted but it should be desirable to apply it to a sampling even better representative of the genus. They also validate the choice of a strategy of dynamic conservation for the wild species. The important genetic recombination suggested to be at the origin of the diversity of cassava gives a favorable perspective for various strategies of genetic mapping and gene tagging, for this crop usually multiplied vegetatively.

Evaluation of germination, shoot growth and rhizofungal flora of Zea mays and Sorghum bicolor in soil contaminated with varying levels of Bonny light crude oil

A B S T R A C T Bonny light crude oil was used at eight different levels ( 0.5%, 1.0%, 2.0%, 2.5%, 5.0%, 10.0%, 15.0% or 20.0% v/w) for the controlled pollution of soil samples to determine its effects on the germination, shoot growth and rhizofungal flora of two vascular plants (maize and sorghum) grown in potted sandy loam soil samples in Nsukka, Nigeria. At low to moderate levels (2% - 2.5%), crude oil suppressed germination of seeds of both crops. At 2.5% level germination time was lengthened by 24h in both maize and sorghum. Complete cessation of germination occurred in sorghum at 5% crude oil level, and in maize at 10% level. Phytochemical analysis showed seeds of both plants lacking saponin and maize seeds having higher percentage of flavonoids and alkaloids, and lower percentage of tannins and phytate. Crude oil significantly (p< 0.05) retarded the shoot growth of the crops in a dose-dependent manner. In maize, at the 7 th week, the mean maximum shoot lengths of the control plant (0% crude oil) and test plants grown in soils with 1%, 2% and 2.5% crude oil levels varied from 60.6cm to 50.7cm, 32.1cm and 11.3cm respectively. For sorghum at the same period, the shoot lengths of the control and test plants varied from 45.5cm to 19cm, 15cm and 7cm respectively. The ability of maize to germinate in crude oil level that was lethal to sorghum makes it better adapted for growth in oil-polluted soils and consequently a better candidate for the phytoremediation of such soils than sorghum. The growth response of rhizosphere and bulk soil fungi was also crude oil - dose dependent.
Effects of seed priming methods on germination and seedling development of winter maize ( Zea mays L.)

Successful establishment of plants largely depends on successful germination. This study examined the effects of different methods of seed priming on germination percentage, germination index, time of 50 per cent emergence, mean germination time, root and shoot length, dry weight of seedling and vigour index of maize. The experiment was conducted in the laboratory of Department of Agronomy, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during 2013-14 using Completely Randomized Design with three replications. All growth and developmental parameters of maize seed were positively responded with seed priming in comparison to unprimed treatment. Bio-priming of maize seed for 24 hours showed the highest positive effect on all the parameters and recorded significantly highest values of germination percentage (93.11), germination index (29.84), root length (22.73 cm), shootlength(19.67), seedling dry weight (1.56 g) as well as seedling vigour index (3947.49). The level of T 50 (1.51 days) and MGT (2.14 days) were the lowest due to bio-priming for 24 hours in comparison to other priming treatments.
GROWTH POTENTIAL OF TWO SPECIES OF BASIL IN SANDY SOIL OF KARACHI

Studies were carried out to examine the growth potential of the two species of Basil viz., Ocimum basilicum L. , and Ocimum sanctum L. , in sandy soil of Karachi. Basil seeds were imported from U.S.A and various stages of their life cycle were investigated in open field. It is shown that both species not only successfully completed their life cycle (germination, vegetative /reproductive growth and seed production) but produced higher amount of viable seeds. It is suggested that these important herbs may be cultivated successfully in Karachi region.

Effects of tillage systems in durum wheat under rainfed Mediterranean conditions

A 2-year conservation agriculture experiment was conducted in Southern Italy on durum wheat continuous cropping. Aim of the research was to assess the durum wheat productivity and grain quality in reduced soil tillage systems, according to conservation agriculture principles. The interactions among experimental treatments and climate revealed a close relationship among grain yield, grain quality and wheat growth conditions. Specifically, conventional tillage (CT, plowing and 2 disc harrowing) showed in the 2-year period higher grain production than reduced tillage treatments, minimum (MT, 1 disc harrowing) and No tillage (NT), especially for good crop water availability (3.29 t ha–1 of grain yield in CT, 2.67 in MT and 2.54 in NT). The amount of rainfall (above the average in both years) and its distribution in the growing seasons (more regular in the first year) strongly influenced wheat-grain quality indices (11.97% of protein content in the first year and 9.82% in the second one). Also, the wheat quali.

This study was carried out to elucidate the effects of oral administration ofGlycyrrhiza glabra root extract on serum lipid profile, liver enzymes, kidney function test, and glucose concentration in albino mice when compared with ten male mice used as control. 40 male mice were treated for one month and equally allocated into four groups: the first group (G1) was used as the control group. The second (G2), third (G3) and fourth groups (G4) were treated with 1 ml of 0.2, 0.7 and 1 mg mL-1day-1, respectively. There was statistically high significance difference between treated and untreated groups for all biochemical parameters, showing a remarkable effect on serum lipid profile, enzymes and kidney function test. G. glabra root extract at low dose act as anti-lipidaemic agent, has hepatoprotective activity for liver cell, prevents renal failure and is an anti-hyperglycemic agent. Key words: Glycyrrhiza glabra, liver enzymes, serum lipid profile, kidney function test, glucose concentration.
Risk reality vs risk perception

Here we explore new tools to improve risk communication within built infrastructure procurement by considering quantitative engineering risk and perceived risk associated with groups of stakeholders. In particular, the perceived risk is assumed to be dependent on motivational values that individuals identify with. The motivational values are evaluated using 40 questions Swartz Portrait Value Questionnaires. Ten hazards are considered in a survey to identify two dimensions, fear and unknown for a specific group of stakeholders. From the outcomes, it was identified that using a hybrid approach to establish the motivational values and risk perceptions for the stakeholder group risk communication could be improved. Furthermore, the outcomes could be used to target information to stakeholders or intervene to ensure that infrastructure performs according to expectation. As a result, it could become possible to revise what are currently inconsistent acceptable risk levels that have been embedded in regulatory documentation.
Transglycosylation to Hesperidin by Cyclodextrin Glucanotransferase from an Alkalophilic Bacillus Species in Alkaline pH and Properties of Hesperidin Glycosides

Cyclodextrin glucanotransferase [1,4-α-d-glucan 4-α-d-(1,4-glucano)-transferase, cyclizing; CGTase, EC 2.4. 1.19] from an alkalophilic Bacillus species produced hesperidin monoglucoside and a series of its oligoglucosides by the transglycosylation reaction with hesperidin as an acceptor and soluble starch as a donor. The formation of the glycosides was more effective at alkaline pHs than at neutral or acidic pHs, because of higher solubility of the acceptor.The structure of the purified monoglucoside was identified as 4G-α-d-glucopyranosyl hesperidin by FAB-MS, α-, β-glucosidase and glucoamylase treatments, and methylation analysis.The solubility of both hesperidin mono and diglucoside in water was about 300 times higher than that of hesperidin, and they were found to have a stabilizing effect on the yellow pigment crocin, from fruits of Gardenia jasminoides, against ultraviolet radiation.

Relationship Between Community Structure and Southern Green Stink Bug (Heteroptera: Pentatomidae) Damage in Macadamia Nuts

Abstract The effect of host weed phenology, abundance, and diversity and natural enemies on the population dynamics of the southern green stink bug, Nezara viridula (L.), in Hawaiian macadamia orchards was investigated. We found that the highest kernel damage occurred immediately following abrupt reductions in the flowering and fruiting stages of host weeds. Areas with the greatest diversity of host weeds showed higher damage, presumably because of higher N. viridula population levels. Predation rates on sentinel egg masses were highest over the two seasons in areas where the bigheaded ant, Pheidole megacephala (F.), comprised a large portion of the ant fauna. In one of the orchards, P. megacephala and the longlegged ant, Anoplolepis longipes (Jerdon), occurred in a spatial mosaic where the boundaries shifted back and forth over time. Sentinel egg masses placed in these two adjacent areas showed predation rates were highest in the areas dominated by P. megacephala, and intermediate in the interface zone and lowest where only A. longipes were found. The importance of weed phenology and natural enemy induced mortality is discussed.

Snoring and Risk of Obstructive Sleep Apnoea in Malaysian Pregnant Women

Chronic hypoxia induced by periods of hypo-oxygenation in obstructive sleep apnoea (OSA) can be associated with reduced foetal growth in pregnancy. Obesity, hormonal and physiological changes during pregnancy plus variations in the craniofacial anatomy could increase the incidence of snoring and possibly OSA. In spite of the high incidence of obesity noted in Malaysia, especially in females, there have been no studies so far conducted to study the prevalence of OSA during pregnancy in this population. Thus, we sought to determine the prevalence of snoring and those who are at high risk for OSA among pregnant women in Malaysia.

Investigation on the efficacy of essential oil extract from leaves of Lippia multiflora on the quality of fresh cow milk during storage

The aim of this study was to evaluate the effect of essential oil from fresh leaves of Lippia multiflora on the conservation of fresh cow milk during storage. The results of microbiological analyses revealed that coliforms and fungi were the most microorganisms identified from fresh cow milk in southern Benin. Chemical analysis by GC/MS of the components of the essential oil extracted from leaves of Lippia multiflora led to the identification of 19 components, characterized by Sabinene (14.4%), 1.8-cineol (50.6%) and α-terpinol (13.8%) as major components. Results obtained during the evaluation of the quality of stored cow milk by adding EO, indicated a significant decrease in the quantum of bacteria and fungi during storage, when compared to the control. However, the best antimicrobial potential were detected with essential oil concentration of 6. 66μL. mL-1. The essential oil of Lippia multiflora, with high antimicrobial property, offers a novel approach to the management of milk and derivate products during storage.
