Several biological markers have been proposed to improve the efficacy of diagnosing tuberculous pleurisy. The study was undertaken to evaluate the accuracy of pleural fluid adenosine deaminase (ADA) activity and interferon-gamma (IFN-gamma) concentration in differentiating tuberculous pleural effusion (TPE) and nontuberculous pleural effusion (non-TPE). Ninety four patients (50 M and 44 F, mean age 60+/-18, range 18-95 years) with pleural effusion (PE) were studied. TPE was diagnosed in patients with: (i) positive pleural fluid or pleural biopsy culture or (ii) granulomas in the pleural biopsy specimen, after exclusion of other granulomatous diseases. Pleural fluid ADA activity was measured with the colorimetric method of Giusti, while IFN-gamma level was measured with ELISA. TPE was diagnosed in 28 patients. The non-TPE group consisted of 35 patients with malignant PE, 20 patients with parapneumonic effusion/pleural empyema, 5 with pleural transudate, and 6 with miscellaneous PE. T...

A two-year experiment (2004-2005) was conducted at Tal Amara Research Station in the Bekaa Valley of Lebanon to evaluate the influence of progressive application of K rates and application timing on yield, yield components and tuber quality of potato (Solanum tuberosum L. cv. Agria). Four levels of potassium (0 (K0), 75 (K75), 150 (K150), and 225 (K225) kg K2O ha-1) and two application timings (tuber initiation and tuber bulking stages) were used in a split-plot design. The progressive application of potassium fertilizer from 0 to 225 kg K2O ha-1 significantly affected the yield and yield components of potato. In both years, small grade tubers and aggregate tuber yield increased quadratically with increasing K application rates up to 150 kg K2O ha-1, reaching a plateau thereafter, showing luxury consumption of the nutrient at 225 kg K2O ha-1. In 2004 when averaged over K application rates, large and medium grade tubers and aggregated tuber yield were 120%, 22%, and 12% greater, resp...

Wet gravity separation technique has been regularly practiced to separate the polypropylene (PP) and polyethylene (PE) (light plastic films) from chlorinated plastic films (CP films) (heavy plastic films). The CP films including poly vinyl chloride (PVC) and poly vinylidene chloride (PVDC) would float in water even though its density is more than 1.0g/cm(3). This is because films are twisted in which air is sometimes entrapped inside the twisted CP films in real existing recycling plant. The present research improves the current process in separating the PP and PE from plastic packaging waste (PPW), by reducing entrapped air and by increasing the hydrophilicity of the CP films surface with ozonation. The present research also measures the hydrophilicity of the CP films. In ozonation process mixing of artificial films up to 10min reduces the contact angle from 78° to 62°, and also increases the hydrophilicity of CP films. The previous studies also performed show that the artificial P...

Background: It has been suggested that diseases that promote isosthenuria predispose to urinary tract infections because of a lack of the common bacteriostatic properties present in concentrated urine.Objectives: The purpose of this study was to assess the clinicopathologic risk factors for positive urine culture outcome in cats with chronic kidney disease (CKD), diabetes mellitus (DM), uncontrolled hyperthyroidism (HT), or lower urinary tract disease (LUTD).Methods: For this retrospective study, medical records of all cats in which a urinalysis and aerobic bacterial urine culture were performed between January 1995 and December 2002 were reviewed. Signalment, body weight, and clinicopathologic data were recorded. Based on the medical records, cats were diagnosed with CKD, DM, HT, or LUTD. Prevalence odds ratios and 95% confidence intervals were calculated using logistic regression. Multivariate models were created for each variable of interest while controlling for the confounding effect of disease group.Results: Six hundred fourteen cats met the criteria for inclusion in the study. Overall, positive urine cultures were identified in 16.9% of cats with CKD, 13.2% of cats with DM, 21.7% of cats with HT, and 4.9% of cats with clinical signs of LUTD. Decreasing urine specific gravity was not associated with positive urine culture when controlled for disease but pyuria, bacteriuria, and hematuria were all associated with positive urine culture outcome. Persians, females, increasing age, and decreasing body weight were all associated with positive urine culture outcome.Conclusions: Performing a urine culture sample based solely on the presence of isosthenuria does not seem warranted. Further studies are warranted to help identify host predisposing factors for urinary bacterial colonization in cats with these diseases.

The IDS (Incubation, Drying and Separation) method was tested on Schinus molle L. seeds collected from Ethiopia in an attempt to sort non-viable from viable seeds. Seeds were incubated for 24 h followed by one, three, four, five, six, nine and twelve hours of drying and then separated in water. All IDS treatments gave 80.5–93.5% germination in the sunken fraction compared with 61% for untreated seeds. The mean germination time of sunken seeds reduced from 11.2 (control) to 8.9–9.2 days (IDS-treated). Specific gravity separation in water of untreated seeds was also tested, and the germination capacity of sunken fraction was 83.5% with a mean germination time of 9.3 days. IDS method can, therefore, be used to enhance both percentage and rate of germination of a seed lot of Schinus molle, which is desirable to produce uniform and vigorous seedlings in the nursery or out in the field.

Recycled glass derived from cathode ray tubes (CRT) glass with a specific gravity of approximately 3.0 g/cm3 can be potentially suitable to be used as fine aggregate for preparing cement mortars for X-ray radiation-shielding applications. In this work, the effects of using crushed glass derived from crushed CRT funnel glass (both acid washed and unwashed) and crushed ordinary beverage container glass at different replacement levels (0%, 25%, 50%, 75% and 100% by volume) of sand on the mechanical properties (strength and density) and radiation-shielding performance of the cement–sand mortars were studied. The results show that all the prepared mortars had compressive strength values greater than 30 MPa which are suitable for most building applications based on ASTM C 270. The density and shielding performance of the mortar prepared with ordinary crushed (lead-free) glass was similar to the control mortar. However, a significant enhancement of radiation-shielding was achieved when the CRT glasses were used due to the presence of lead in the glass. In addition, the radiation shielding contribution of CRT glasses was more pronounced when the mortar was subject to a higher level of X-ray energy.► It is feasible to use recycled CRT glass in mortar as shield against X-ray radiation. ► Shielding properties of CRT mortar is strongly depended on CRT content. ► Linear attenuation coefficient was reduced by 142% upon 100% CRT glass in mortar. ► Effect of mortar thickness and irradiation energies on shielding was investigated.

Purpose of the study: The main purpose of this study is to find out the effect of change in soil viscosity, soil temperature and specific gravity on growth of plants sown in the soil prepared from laboratory chemical waste collected from an educational institute and with the plants sown in normal soil.
Methodology: Three-three pots with different soil combinations mixed with solid and liquid chemical waste have been used for growing A. barbadensis Mill, Saussurea obvallata and Lilium plants. Observations were made every fifteen days for three months by checking plant height, the number of leaves, the color of leaves and soil temperature for understanding and comparison of plant growth with respect to variation in temperature. Later on density and viscosity of soils have also been checked with the help of specific gravity bottle and viscometer.
Main Findings: Plants' growth differs with variation in soil viscosity, soil temperature, and soil density. All plants cannot grow potentially at the same temperature, viscosity, and density. A. barbadensis Mill A4 has shown better growth with least viscosity and highest particle density of soil. Saussurea obvallata BK1 has shown better growth with least viscosity and least particle density of soil. Lilium L1 has shown better growth with all the moderate values of soil.
Applications of this study: This study helped to understand that all the plants have their own requirements of nutrients, nutrition and physical factors for their growth. This also helped to understand that although the soil has taken initially is the same, viscosity and density of the soil changes due the plants grown in it.
Novelty/Originality of this study: The use of chemical wastes is taken into consideration instead of fertilizers to reduce pollution.

The waste materials utilization in concrete production is very much helpful in reaching the goal of sustainable construction. Therefore, this study intends to use coconut shells and fly ash by replacing coarse aggregate and cement, respectively, in concrete. The paper reports on the performance of M30 grade of concrete mixes containing different ratios of coconut shell having 20 mm maximum size as coarse aggregate. Ordinary Portland Cement 33 grade and coarse sand were used to produce standard concrete cubes. Compressive strength tests were carried out on concrete specimens of various ages. Test results indicate that except for the M30 mix, there is no significant effect on compressive strength of concrete up to 20 percent replacement of normal 20 mm coarse aggregates with coconut shells. But beyond that, strength started decreasing gradually with an increase in the proportion of CS aggregates in concrete.

The machinery and operations when improperly designed may generate rice kernel cracking and breakage and consequently a low marketing price. The objective of this work was to determine the influence of the rice processing operations on physical and mechanical properties of different rice varieties. Three varieties of rice, rough, brown and milled, were used in this work. The bulk densities of all varieties increased with processing up to 51% and there were differences among the varieties; the rice grain specific gravity was influenced neither by the processing nor by the varieties. The processing influenced the porosity of the bulk rice grains; the external static and dynamic friction coefficients were reduced. The higher friction coefficient values were observed on wood surface and the lowest on steel surface; the compression force needed to promote the rice kernel collapse was affected significantly by the processing.

This article was prepared with W.A Oddy. Essentially it just introduces a programme of research that Andrew Oddy undertook in the late 1970s and early 1980s on Gold coins of Central and South Asia. He carried out extensive specific gravity tests (a measure of density) on the coins which made it possible to understand the gradual debasement of those coins. An analysis of that work was published by Andrew with Joe Cribb in Ex Moneta, 1998. However the results themselves only existed on file cards. The link takes you to a complete spreadsheet of the data.
