Luminescent Ag<SUB>7</SUB> and Ag<SUB>8</SUB> clusters by interfacial synthesis

Interfacial etching of silver nanoparticles and separation of the products by polyacrylamide gel electrophoresis afforded Ag8 and Ag7 clusters with red and blue-green fluorescence emission, respectively (see picture). The strongly temperature-dependent emission of the clusters suggests potential applications, whilst their facile phase transfer to organic media facilitates further studies

Knowledge, attitude, and practice of epilepsy in rural Sri Lanka

AbstractKnowledge, attitude, and practice in relation to epilepsy in developing countries appears to be different from that in developed countries. This study was conducted to evaluate knowledge, attitudes, expectations, sociocultural aspects, patient characteristics, disease characteristics, pattern of drug therapy, and outcome of patients with epilepsy in rural Sri Lanka. Data were collected from 207 patients attending an epilepsy clinic. In general the study shows a positive trend in knowledge, expectations and attitude toward epilepsy. Social morbidity is reported from 53.6% indicating that public attitude towards epilepsy needs to be changed. Alternative modes of treatment have been tried by 45.9%, reflecting the cultural beliefs in the society. 75% are on monotherapy and carbamazepine is the most commonly used drug. Seizure control is excellent (no seizures during the preceding 6 months) in 33.8%. Side effects of antiepileptic drugs are reported by 76.3%. Various kinds of medical morbidity have been experienced by 32.9% of patients

Inferring mixed-layer depth variability from Argo observations in the western Indian Ocean

The seasonal and spatial variability of mixed layer depth (MLD) was examined in the Western Indian Ocean (WIO) (30E – 80E and 10S – 30N) for three consecutive years starting from June 2002 – May 2005 using Argo temperature and salinity (T/S) profiles. These were compared with MLD estimates from World Ocean Atlas 2001 (WOA01) T/S data. Temporal and spatial variability of MLD estimated from Argo T/S profiles were found to correspond well with the MLD obtained from WOA01 T/S data. However, slight deviations in the form of months of occurrence of minima and maxima MLDs were observed. MLD from WOA01 climatology is underestimated compared to MLD from Argo for almost the entire three years of study. It is also observed that MLD variability features as brought out by both the data sets followed the dynamics that govern the mixed layer variability in this region

Effect of Training in Lip Reading on Speech Reception of Children with Hearing Impairment in Inclusive Education Classroom in Nigeria: Implication for Regular Teachers.

The study investigated the effect of training in lip reading on speech reception of children with hearing impairment in inclusive classroom in Nigeria and its implication for regular teachers. Quasi-experimental design of pretest-post-test design with two experimental groups receiving equal treatment on lip reading training (LRT) was used for the study. The population of the study was thirty six (36) children with hearing impairment in primary five in primary school for the deaf in Enugu Nigeria. The instrument for data collection was researchers’ made test called Lip-Reading Test (LRT) drawn from everyday sentences of IOWA- Keaster forms A and B. Mean and standard deviation was used to analyse the data and ANCOVA to test the hypotheses. The findings revealed that the use of amplification (hearing aid) facilitated the reception of speech by children with hearing impairment (CWHI). The study then recommended that training in lip reading should be given to children with hearing impairment (CWHI) and teachers to be equipped to participate and interact effectively in the inclusive education classroom CWHI. Keywords: Inclusion, impairment, images, perception, receptio

Physiological approaches to improving harvest index and productivity in sunflower

Factors associated with variation in harvest index and approaches to improve harvest index (HI) and productivity in sunflower are discussed in this article. In recent years, higher productivity in sunflower has been achieved mainly through increased crop growth rates. Besides, an improvement in harvest index also has contributed for improved productivity to a certain extent. In our study we observed that medium duration types (100 to 110 days) had high HI compared with early or long-duration varieties and we also attempted to understand the ways and means to improve HI in sunflower types with varied duration. Genotypes which had low partitioning of dry matter to stem plus thalamus had high HI. Genotypes which accumulated high biomass during post flowering stages of development also showed high HI and seed yield. In a few genotypes remobilization of photosynthates from vegetative plant parts to the seed resulted in high HI and seed yield. Among the sink characters, the number of seed per head, test weight and seed density (weight/volume) also contributed to achieving high HI values. Identification and selection of genotypes based on these criteria will increase the production further. Since large amount of biomass is still locked up in the vegetative plant parts, any practice to manipulate the mobilization of photosynthates from vegetative parts to head also improves HI and thus seed yield. In our experiment, we observed that foliar application of boron nutrient and application of growth regulators to the head improved the translocation of photosynthates to the head and thus increased the HI and seed yield

Performance Evaluation of Water-Injection Cyclone Treating a Synthetic Mixture

The effect of change in operating variables i.e., vortex finder diameter,spigot diameter nd water injection rate on different performance numbers is studied in water-injection cyclone treating a synthetic mixture of atomized Ferro-silicon and ground silica sand. Suitable empirical models relating the operating variables and fines (below 25 microns) recovery, ferro-silicon and silica recoveries in the overflow productand the separation efficiency at 25 microns size are developed. At comparable levels of ope-rating throughput, the performance numbers obtained in a 100mm water-injection cyclone and a 100mm normal hydro- cyclone are discussed. An overall fines recovery of 85.6% was obtained in the overflow product of water-injection cyclone whereas in a normal hydrocyclone the combined fines recovery in the overflow product was 46.2%. Similarly the ferro-silicon recovery at fines below 25 microns in the overflow product from water-injection cyclone was 55.5% while that of hydro-cyclone was only 9.8%. Also, silica recovery at fines below 25 microns in the overflow product of a water-injection cyclone was 98.6% in comparison to 82.1% in a normal hydrocyclone. Separation efficiency values obtained between coarse and fine products at 25 microns in the overflow product of water-injection cyclone and hydro-cyclone were 83.5% and 45.8% respectively which indicates sharper classification in water-injection cyclone

CRAM ON LIVE LOADS ON BY USING LAMINATED COMPOUND WARPED PLATES

As compared to standard concrete the advantages of SCC comprising more electricity like non SCC, can be better because of better compaction, comparable tensile strength like non SCC, modulus of elasticity can be barely reduced because of better paste, barely better creep because of paste, shrinkage as normal concrete, better bond electricity, fireplace resistance similar as non SCC, durability better for better floor concrete. Incorporation of fibers in addition enhances its residences especially associated with put up the crack behaviour of SCC. The fibers used in the searching at are 12 mm lengthy chopped glass fiber and carbon fiber. The amount fraction of fiber taken is zero%, 0.1%, zero.15%, zero.2%. The assignment made out of levels. The first level consisted of the development of SCC aggregate design of M30 grade and inside the second degree, specific fibers like Glass and carbon Fibers are introduced to the SCC mixes and their glowing and hardened houses have been determined and in assessment. This shape of concrete is referred to as self-compacting concrete (ssc). In the prevailing take a look at, fiber reinforcements are introduced to observe the bodily, chemical and mechanical houses of the self-compacting concrete (scc) Fibers are delivered to concrete to boom the flexural power of concrete and to arrest the cracking sample advanced inside the concrete

Fast Evaluation of Ensemble Transients of Large IP Networks

We extend a numerical approximate solution method (the Z-iteration) to time-dependent open networks of M(t)/M(t)/1/$\infty$ and M(t)/M(t)/1/K queues, and apply the method to obtain transient performance metrics of large IP networks. The method generates a set of coupled differential equations, one for each queue in the network. The equations are numerically unstable under certain conditions (e.g., large bandwidths and buffers), and we present techniques to overcome this problem. The resulting numerical procedure is accurate and very fast. For example, a 20-second evolution for a 1000-node network with high-speed links ($\approx 10^4$packets/sec) and large buffers ($\approx 10^4$packets) was obtained in 18 minutes on an Ultra Sparc, whereas simulation would take days
