Borehole geology and sub-surface petrochemistry of the Domes area, Olkaria geothermal field, Kenya, in relation to well OW-922.

Olkaria is a high temperature geothermal system located within the central sector of the Kenya Rift System, and associated with a region of Quaternary volcanism. Recharge into the system is exclusively by meteoric water, derived primarily from the high-altitude rift escarpments. Tectonic structures play without a doubt a pivotal role in enhancing fluid flow within the geothermal system. For this study, data and samples from four wells, OW-905A, OW-910, OW-917 and OW-922, have been used. Wells OW-905A, OW-910 and OW-917 were drilled within and along the proposed caldera structure. Well OW-922 is a step-out vertical well, drilled to the east of the proposed caldera structure. This study largely focuses on well OW-922, while, the other three wells have been included for comparison purposes. The study presents a comprehensive look at the borehole geology and hydrothermal mineralisation, sub-surface petrochemistry and microprobe analysis. Lithologies intersected by the study well include pyroclastics, tuff, rhyolite, basalt, trachydacite, basaltic trachyandesite, trachyandesite and trachyte. No intrusions are found in this well. Hydrothermal products in the study well occur both as replacement of primary components or glassy matrix and as open space filling in veins, fractures and vesicles. Evidence of a significant cooling process (up to over 110C) in the geothermal system around the study well is provided by the difference between measured formation temperature (127C) and inferred hydrothermal alteration temperature (epidote 240C). Cases of calcite overprinting epidote further points towards a cooling process. Five feed zones have been deduced from the well and all are categorised as small. Generally, the well has low permeability and could not sustain discharge after 49 days of heat-up. Observations from temperature distribution across the field indicates that the study well is located outside the Olkaria Domes heat source, and consequently, outside the main Olkaria volcanic zone. Whole-rock chemistry displays a range of compositions of the samples of the study well, from basalt to trachyte or rhyolite, with the prevalence of the rocks being the highly evolved derivatives. Major oxides and trace element systematics are dominated by crystal fractionation, even though other differentiation processes cannot be ruled out. Evidence of a common differentiation mechanism for the surface and sub-surface rocks seems likely on the basis of comparison between the two groups of samples. Microprobe analyses have been carried out on epidote and chlorite in order to assess the chemical composition and the compositional range of the two minerals. It is found that most of the epidote are aluminium-rich, whereas, the chlorites are iron-rich varieties. Limited number of epidote and chlorite has however, impeded possible correlation of the stratigraphy in the four wells based on major and minor element contents.

Implementation of Self Reporting Pharmacovigilance in Anti Tubercular Therapy Using Knowledge Based Approach

Tuberculosis (TB) hampered with poor patient compliance and intolerance at least partially due to adverse drug reactions (ADRs). A prospective observational and interventional healthcare teamwork study was carried out to implement a self-reporting pharmacovigilance system in TB patients through a knowledge based approach in the Pulmonology department of Kovai Medical Center and Hospital (KMCH) at Coimbatore. A patient information pamphlet which was endorsed by the pulmonology associates was the core tool for this study. A well practiced and skilled clinical pharmacist educated the patients and enabled them to report the ADRs due to anti tubercular drugs through the emergency number given in the pamphlet. Totally 110 patients enrolled in the study. 43 (39%) patients experienced 74 numbers of ADRs during the intensive phase therapy. Out of 110 patients, 101 were adhered to the intensive phase therapy. Of the 74 ADRs experienced to our study population, 24 ADRs were occurred in 18 patients which are needed to be self reported by the patient according to the study protocol. Among 24 ADRs which have to be self reported, 20 (83.33%) ADRs were reported through 17 calls by 16 patients. The self-reporting pharmacovigilance for anti-tubercular therapy in pulmonology department of KMCH, Coimbatore, were implemented and was certified by the pulmonology associates. Our study concludes that if a proper educational system is implemented, most of the patients were ready to report their ADR of any drug and thereby we can improve both patient adherence and reducing the severity of ADRs. It is suggested that the pharmacists should exhibit their vital role during TB therapy in TB centres, pulmonology departments and DOTS centres to guarantee a better patient care.

Interaction between mineral particles during ascharite flotation process and direct force measurement using AFM

Interaction between mineral particles during ascharite flotation was investigated by flotation, zeta potential, Derjaguin-Landau-Verwey-Overbeek (DLVO) theory, atomic force microscope (AFM) and SEM-EDS tests. Flotation results showed that the ascharite recovery decreased significantly in the presence of serpentine. In order to improve the ascharite recovery, negative charged quartz was used to limit the detrimental effect of serpentine on ascharite flotation in this research. The effect of quartz on improving ascharite recovery was attributed to the particle surface interactions. The DLVO theory was applied to study the particles interaction in the aqueous solution. The fitting curves showed that serpentine could attach to the surface of quartz easily, and quartz would be well dispersed with ascharite. Therefore, quartz can improve the ascharite flotation performance effectively by interaction between particles. Zeta potential tests showed the opposite charges on the surfaces of mineral particles, which was the basic reason leading to particles interaction. The force measurement results of AFM indicated that the attraction force existed between serpentine and ascharite, as well as serpentine and quartz, but the force between quartz and ascharite was repulsive. The DLVO theory was in a good agreement with the results of AFM. Eventually, particles coating were observed by SEM-EDS, which supported the results of DLVO theory and AFM measurements. During the flotation process, addition of quartz would lead to attachment of serpentine to the quartz surface, so the adverse effect of serpentine on decreasing floatability of ascharite was weakened.
Cutaneous Vasculitis Associated to Cystic Fibrosis

Cutaneous vasculitis is a rare complication of cystic fibrosis. The exact incidence is unknown because there are only isolated cases reported. It usually affects patients with severe lung disease and it is believed to be associated with a worse prognosis. While the skin is the most frequently affected site, vasculitis may involve other organs. We present a patient diagnosed with cystic fibrosis since childhood, with a history of liver transplantation and controlled lung disease. At the age of 18 years, the patient consulted with recurrent episodes of cutaneous vasculitis. Three years later, associated with an increase in skin rash, he evolved with severe respiratory failure and cardiopulmonary transplant requirement.
Undergraduates’ use behavior of learning management systems: a Sri Lankan perspective

This research aims to explore the perceptions of students in using Learning Management System (LMS) in order to enhance the learning process of students, especially those undergraduates in government universities in Sri Lanka. Almost all government universities in Sri Lanka have implemented LMS for students to make their learning process interactive and engaging. These higher educational institutions have made considerable amount of investments in terms of finance and other resources, but the benefits enjoyed by these institutions and student are far below expectations unless the usage of such systems are made compulsory. Therefore, although many studies have been conducted overseas, it is of high recognition that a study is very much needed to understand the reason(s) for low usage by students in Sri Lankan free education context. Quantitative study based on self-administered questionnaire survey was conducted. Out of the 15 government universities in Sri Lanka, 03 were selected. Results from 344 valid responses reveals that Attitude, Experience and Anxiety significantly influence the students’ use behaviour of LMS in Sri Lankan universities, while Efficacy and Collaboration do not have any impact. The research identifies what factors would influence these students’ use behaviour of LMS in state universities. Variables Students’ Attitude towards LMS, Efficacy, Experience, Anxiety and Collaboration with Lecturers and Students are considered to be the predictor variables and their influence and impact on Use Behaviour of LMS (predicted variable) is studied. Keywords: Undergraduates’ Perspectives, Learning Management Systems, Use Behaviour, Sri Lankan Universities.
Exact power spectra of Brownian motion with solid friction

We study a Langevin equation describing the Brownian motion of an object subjected to a viscous drag, an external constant force and a solid friction force of the Coulomb type. In a previous work (Touchette et al 2010 J. Phys. A: Math. Theor. 43 445002), we have presented the exact solution of the velocity propagator of this equation based on a spectral decomposition of the corresponding Fokker–Planck equation. Here, we present an alternative, exact solution based on the Laplace transform of this equation, which has the advantage of being expressed in closed form. From this solution, we also obtain closed-form expressions for the Laplace transform of the velocity autocorrelation function and for the power spectrum, i.e. the Fourier transform of the autocorrelation function. The behavior of the power spectrum as a function of the dry friction force and external forcing shows a clear crossover between stick and slip regimes known to occur in the presence of solid friction.
Evolution of gaseous precursors and meteorological parameters during new particle formation events in the Central European boundary layer

This paper revisits the atmospheric new particle formation (NPF) process in the polluted Central European troposphere, focusing on the diurnal evolution of the meteorological and gas phase parameters involved. Atmospheric aerosol observations include Neutral cluster and Air Ion Spectrometer (NAIS) measurements at the research station Melpitz, East Germany between 2008 and 2011. Particle formation events were classified by a new automated method based on the convolution integral of particle number concentration in the diameter range 2–20 nm. To study the relationship with gaseous precursors, a proximity measure was calculated for the sulfuric acid concentration on the basis of a one month intensive measurement campaign in May 2008. A major result was that the number concentration of fresh produced neutral particles correlated significantly with the amount of sulfur dioxide available as a main precursor of sulfuric acid. The condensation sink, a factor potentially inhibiting NPF events, played a subordinate role only. The same held for experimentally determined ammonia concentrations, which also represent a recognised precursor of aerosol particle nucleation. The analysis of meteorological parameters confirmed the absolute need for solar radiation to induce NPF events, and demonstrated the presence of significant turbulence during those events. Due to its tight correlation with solar radiation, however, an independent effect of turbulence for NPF could not be established with certainty. On the basis of observed diurnal cycles of aerosol, gas phase, and meteorological parameters near the ground, we conclude that particle formation is likely to be induced aloft, rather than near the ground.
Numerical Study on Flat Plate and Leading Edge Film Cooling

This study describes a 3-D computation for film cooling effectiveness investigation using Fluent commercial code, version 6.2. Two configurations are examined: (1) Flat plate, and (2) Semi-cylindrical leading edge with a flat after-body. Three different RANS turbulence models and DES based on Spalart-Allmaras model are utilized to see the difference in accuracy between DES and RANS approaches. Similar to the previous RANS simulation, lateral spreading of film cooling is under-estimated in the RANS simulation, while in the DES, lateral spreading of film cooling is enhanced and shows adequate agreement with the previous experiments. The effects of velocity magnitude and orientation of plenum flow on film cooling effectiveness are also studied in the flat plate configuration. The plenum flow is eventually found to have a strong impact on the flow structure in the cooling pipe, and the distorted velocity profile in the pipe consequently lowers film cooling effectiveness, in particularly at high blowing ratio.Copyright © 2009 by ASME
Computation of Transverse Injection Into Supersonic Crossflow with Various Injector Orifice Geometries

Computational results are presented for the performance and flow behavior of various injector geometries employed in transverse injection into a non -reacting Mach 1.2 flow. 3 -D Reynolds -Averaged Navier Stokes (RANS) results are obtained for the various injector geometries using the Wind code w ith the Mente r’s Shear Stress Transport turbulence model in both single and multi -specie s modes. Computed results for the injector mixing, penetration, and induced wall forces are presented. In the case of rectangular injectors, those longer in the direct ion of the freestream flow are predicted to generate the most mixing and penetration of the injector flow into the primary stream. These injectors are also predicted to provide the largest discharge coefficients and induced wall forces. Minor performance differences are indicated among diamond, circle, and square orifices. Grid sensitivity study results are presented which indicate consistent qualitative trends in the injector performance comparisons with increasing grid fineness.
Studies on genetic variability and interrelationship among the different traits in Microsperma lentil (Lens culinaris Medik.)

The genetic parameters, character association and path coefficient analysis between yield and yield contributing characters of 25 lentil genotypes were studied during 2007 - 2008 at Kisan (PG) College, Simbhaoil. The genotypes exhibited a wide range of variability for all the traits studied. High heritability accompained by moderate to high GCV and genetic gain were observed for number of pods plant-1, number of branches plant-1, 100 seed weight, seed yield plant-1 and harvest index. Correlation studies indicated that number of pods plant-1, biological yield and harvest index were positively and significantly correlated with seed yield at both phenotypic and genotypic levels. Path coefficient analysis showed that harvest index, biological yield and number of pods plant-1 showed maximum and positive direct effect on seed yield. Key words: Correlation, path coefficient analysis, genetic variability, lentil.
Root Growth, Nutrient Uptake and Yield of Medicinal Rice Njavara under Different Establishment Techniques and Nutrient Sources

Field experiments with medicinal rice Njavara were conducted at Cropping Systems Research Centre, Karamana, Thiruvananthapuram, Kerala during summer of 2007 and 2008. The experimental design was split plot with three replications. The treatments consisted of four establishment techniques viz., System of Rice Intensification SRI (M1), Integrated Crop Establishment Method (ICM) (M2), Package of practices (PoP) (M3) of Kerala Agricultural University and Conventional Management Practices (CMP) (M4) in main plot. Three nutrient sources viz., (1) organic, 2) integrated use of organic and inorganic, 3) chemical fertilizers only) were used under different establishment techniques. Root dry matter production was determined at weekly intervals and plant nutrients uptake was determined by calculating from the product of dry matter, straw dry weight, grain yield and percentage of nutrients. Results revealed that at early stages (4-6 WAT/WAS) (Weeks after transplanting/Weeks after sowing), root dry matter production hill-1 was in the order of SRI > ICM > CMP > PoP which changed to SRI > ICM > PoP > CMP from 7th week onwards. Maximum root dry matter (at 9th WAS/WAT) was recorded in SRI (0.51/0.50 g.hill-1 in 2007/2008). The total nutrients uptake (N, P, K, Fe, Mn and Zn) in conventional management practices was significantly higher than other establishment techniques. Among the nutrient sources, higher total (N, P, K, Fe, Mn and Zn) uptake by crop was recorded under integrated nutrient source than organic and inorganic sources.
The development of dairying in Europe: potential evidence from food residues on ceramics

Providing evidence of dairying is crucial to the understanding of the development and intensification of Neolithic farming practices in Europe, beyond the early stages of domestication. Until recently, research in this field had been limited to traditional archaeological methods, such as the study of pottery styles, faunal remains and specialised material artefacts. Although suggestive, these methods are unable to provide direct evidence of dairying. Advances in biomolecular methods now allow the identification of remnants of dairy products on ceramic vessels and the application of these methods to Neolithic ceramic assemblages across Europe is underway. There is no doubt that these new methods offer much scope for investigating hypotheses such as the ‘secondary products revolution’, but there are limitations. The cost of analyses prohibits indiscriminate sampling and differential survival is likely to prevent direct comparison of samples from different sites. Only by incorporating these techniques within the wider frameworks of archaeological research may theories be properly tested. Approaches to achieve this goal are discussed.
Apoptosis in vascular diseases — clinical implications, review of the literature

Since the time of the first apoptotic death descriptions a lot of new information concerning the importance of this process has been discovered. There are still more and more data about clinical implications of this knowledge in physiological conditions and pathological states. The technical progress concerning molecular biology allows to detect very early stages of this process — on the other hand, the knowledge concerning stimuli factors and regulatory mechanisms of PCD still increases. Special interest is focused on neoplasmatic and vascular diseases and also on research concerning apoptotic pathways and their modulatory mechanisms. In the paper, the review of the literature describing the role of apoptosis in the vascular diseases was presented.
Effect of Alkali Treatment of Wheat Straw on Adsorption of Cu(II) under Acidic Condition

The convenient and feasible pretreatment method of alkali treatment is very common in the degradation process of wheat straw. However, its utilization in the pretreatment of wheat straw as alternative adsorbents for aqueous heavy metals remediation is rarely reported. The present study investigated the removal efficiency of Cu(II) ions using wheat straw with alkali pretreatment. The condition of alkali treatment on wheat straw was optimized with the adsorption capacity of Cu(II) as indicator using single-factor experiments. The influences of wheat straw dosages, pH values, contact time, and temperatures on adsorption performance for both untreated wheat straw (UWS) and alkali-treated wheat straw (AWS) were investigated. Results showed that the relatively large removal rate of Cu(II) could be obtained, and chemical behavior occurred during the adsorption process. Characteristic analysis found that the major function of alkali treatment to wheat straw was to introduce the hydroxy group, which resulted in the increase of -C-O- group. Although the adsorption capacity is not as high as the one of ligands supported adsorbents, the method is easy to operate and has a wide range of application; at the same time, it could realize both purposes of treating heavy metal pollution and solid wastes.
