Variations in reaction and total soluble salts of a red-brown earth from South Australia have been assessed. Seasonal changes are discernible for reaction but are largely masked by spatial variations even over small areas. The amplitude of the seasonal changes is of the order of 0.15 of a pH unit, the soil returning to the same pH value during the succeeding season. Spatial variations have been found for organic carbon, nitrogen, clay, and exchangeable cations over small areas. Data have been presented to show that while the mean soil reaction does not vary widely, there is a variation in the variance of the reaction values about the mean with season. The change of the reaction status of the soil with time over a small area does not consist of a uniform increase and decrease of 911 the reaction values in the area but rather of a reorganization of all hydrogen ion contributing factors to give difference in dispersion about the mean value.

In an experiment with a completely randomized design of 4 treatments, 4 replications, one experimental unit consisting of 5 randomly divided chicken chickens. The four replications were consistent with four treatments from the study, each containing P0, P1, P2, and P3 were 0% (control), 5%, 10%, and 15%. Melinjo emping flour (Gnetum gnemon) is as an additional feed obtained from the market. The research variables were: pH, Water content, and Chicken Meat Meat Consumption. The results showed that the level of using melting chips (Gnetum gnemon) did not give effect to meat pH (P> 0,05) while in water content and shrinkage Chicken meat showed a very significant difference of influence (P <0.01). The mean pH value at treatment P0, P1, P2, and P3, was 5.9; 5.9; 6.0 and 5.9. The average value of water content in the treatment of P0, P1, P2, and P3 was 79.30; 84.90; 83.30, and 83.40. The mean value of shrinkage of chicken meat in treatment P0, P1, P2, and P3 was 2.7; 4.2; 4.7 and 4.7. It was concluded that the addition of emping melinjo starch (Gnetum gnemon) had an effect on water content and shrinkage of chicken meat. However, the use of emping melinjo flour (Gnetum gnemon) is not significant at the pH of chicken meat.

Measurements have been made of seasonal changes in soil salinity and soil water at Tintinara in the Coonalpyn Downs of South Australia. Five separate sites representing different soil profiles were selected for study. All soils contained saline water-tables and four of the five had varying depths of sand over finer-textured subsoils; the fifth soil was fine-textured throughout. The investigations were conducted over a 12-month period, salinity and water determinations being made every 8 weeks. Data on soil salinity are presented as: (1) Conductance of soil pastes, determined on replicates and statistically analysed. (2) Percentage of total soluble salts, derived from conductivities of 1:5 soil-water suspensions determined on composite sample. (3) Percentage of chlorides expressed as NaCl, determined on composite samples. All sets of data show that soluble salts moved upwards through the soil profile during spring and summer and down during the rainy season. Where the summer water-table was within 4 ft of the surface large amounts of saline material accumulated in the top inch of soil; in one case there was an increase of from 0.019 per cent. NaCl in winter to 3.2 per cent. in summer. Data are also presented showing that the salinity of the ground-waters increased to a maximum of 2-3.5 per cent. total salts in spring or summer. Seasonal soil water changes are recorded and discussed in relation to salinity changes. The climatic, soil, and ground-water factors influencing salt movements are discussed and the agronomic implications of seasonal salinity changes are stressed. Suggestions on the basis of the results obtained are made respecting the sampling of saline soils.

Organophosphates have been used to eradicate pests and prevent losses from harvest failures caused by pest attack. It is undeniable that the organophosphate persist in soil. This study aims to identify the organophosphate residue and soil properties include pH, soil texture, and permeability. The soil samples were taken from cropland in 10 villages, Wanasari sub-district, Brebes, Indonesia. Organophosphate residue determined by gas chromatography using Flame Photometric Detector. Soil texture was determined by soil texture triangle from NRCS USDA, and the permeability value was determined by falling head method. The mean value of chlorpyrifos, profenofos, diazinon were 0.0078; 0.0388; 0.2271 mg/l respectively. The soil texture varies from clay, silt clay, loam, silt loam, and silt clay loam with permeability value at 10-7 with the soil pH value between 6.4 – 8.1. The results showed that organophosphate residues found in the soil and its potential affect the soil fertility decline. We recommend to conduct routine soil quality analysis to prevent soil damage in the agricultural environment.

Aim: This study aims to compare the random blood sugar pH of the blood. Introduction: Hyperglycemia is a risk factor for the impairment of periodontal health while periodontal disease, in turn, is responsible for the adverse effects on glycemic control and the pathophysiology of diabetes-related complications. An increase in blood sugar levels has a direct effect on pH with respect to age. Hence this study deals with the association of random blood sugar levels and pH with age, gender, and dental complaints. Materials and Methods: 20 random blood samples were collected from the patients in Saveetha Dental College. The random blood sugar level was analyzed by the semi-quantitative method and the pH was analyzed by using a multi reagent strip. And the results were statistically analyzed using SPSS software and represented as pie charts and bar graphs. Results and Discussion: The overall mean value of RBS and blood pH was found to be 138.4 mg/dl and 7.06 respectively. The mean RBS value is higher in the 41-50 years age group of people than in other age categories and the mean pH value is same for all age categories. In the present study, samples with periodontic complaints have higher mean value of RBS values (193) than other dental complaints and the mean pH value is same for all dental complaints. Conclusion: Within the limits of the study, it can be observed that there is a significant association between the age group, gender, and dental complaints with RBS and pH of the patients. However, further studies must be conducted to have more accurate results and elicit the association between pH and RBS with age and gender.

Pd-Ce alloys exhibit various anomalies in physical properties due to mixed valences of Ce, and the anomalies are thought to be strongly related with the crystal structures. Since Pd and Ce are both heavy elements, relative magnitudes of (fcc-fpd) are so small compared with <f> that superlattice reflections, even if any, sometimes cannot be detected in conventional x-ray powder patterns, where fee and fpd are atomic scattering factors of Ce and Pd, and <f> the mean value in the crystal. However, superlattices in Pd-Ce alloys can be analyzed by electron microscopy, thanks to the high detectability of electron diffraction. In this work, we investigated modulated superstructures in alloys with 12.5 and 15.0 at.%Ce.Ingots of Pd-Ce alloys were prepared in an arc furnace under atmosphere of ultra high purity argon. The disc specimens cut out from the ingots were heat-treated in vacuum and electrothinned to electron transparency by a jet method.

The relative partition coefficients of krypton and xenon, and the regional blood flow in 27 superficial malignant tumour nodules in 22 patients with diagnosed tumours were measured using the 85mKr- and 133Xe-clearance method. In order to minimize the effect of biological variables on the measurements the radionuclides were injected simultaneously into the tumour. The distribution of the radiotracers was assumed to be in equilibrium at the beginning of the experiment. The blood perfusion was calculated by fitting a two-exponential function to the measuring points. The mean value of the perfusion rate calculated from the xenon results was 13 ± 10 ml/(100 g-min) [range 3 to 38 ml/(100 g-min)] and from the krypton results 19 ± 11 ml/(100 g-min) [range 5 to 45 ml/(100 g-min)]. These values were obtained, if the partition coefficients are equal to one. The equations obtained by using compartmental analysis were used for the calculation of the relative partition coefficient of krypton and xenon. The partition coefficient of krypton was found to be slightly smaller than that of xenon, which may be due to its smaller molecular weight.

SummaryIn the present paper described is a simple test for detecting soluble fibrin monomer complexes (SFMC) in blood. The test consists in mixing 1% protamine sulphate with diluted oxalated plasma or serum and reading the optical density at 6190 Å. In experiments with dog plasma, enriched with soluble fibrin complexes, it was shown that OD read in PS test is proportional to the amount of fibrin recovered from the precipitate. It was found that SFMC level in plasma increases in rabbits infused intravenously with thrombin and decreases after injection of plasmin with streptokinase. In both cases PS precipitable protein in serum is elevated indicating enhanced fibrinolysis. In healthy human subjects the mean value of OD readings in plasma and sera were found to be 0.30 and 0.11, while in patients with coronary thrombosis they are 0.64 and 0.05 respectively. The origin of SFMC in circulation under physiological and pathological conditions is discussed.

SummaryThe plasma tissue factor (TF) concentration was correlated to factor VII concentration (FVIIag) and factor VII activity (FVIIc) in 498 healthy volunteers ranging in age from 17 to 64 years. Immunoassays using monoclonal antibodies (mAbs) were developed for the determination of TF and FVIIag in plasma. The mAbs and the test systems were characterized. The mean value of the TF concentration was 172 ± 135 pg/ml. TF showed no age- and gender-related differences. For the total population, FVIIc, determined by a clotting test, was 110 ± 15% and the factor VIlag was 0.77 ± 0.19 μg/ml. FVII activity was significantly increased with age, whereas the concentration demonstrated no correlation to age in this population. FVII concentration is highly correlated with the activity as measured by clotting assay using rabbit thromboplastin. The ratio between FVIIc and FVIIag was not age-dependent, but demonstrated a significant difference between men and women. Between TF and FVII we could not detect a correlation.

SummaryThe plasminogen content was determined by a casein method in plasma and serum from 20 normal volunteers. The mean plasminogen content was found to be 10.1 ACU (the arbitrary caseinolytic unit defined in such a way that using a 3% casein solution and a digestion time of 20 min. at 37°C, 10 ACU gave an extinction of 0.300). No difference between serum and plasma regarding the plasminogen content was found.Plasminogen was determined in drained and drained plus washed clots prepared from 2 ml plasma. The highest values found in the drained clots were 0.9 ACU/clot and 0.2 ACU/clot in the drained plus washed clots.Plasminogen was also determined in drained and drained plus washed clots prepared from plasma with added purified plasminogen. The plasminogen was recovered in the washing fluid. According to these tests, then, purified added plasminogen is washed out of the clots.The plasminogen content of 20 thrombi obtained post mortem was also determined. The mean value was found to be 0.7 ACU/cm thrombus. Judging from our results, the “intrinsic clot lysis theory” is not the main mechanism of clot dissolution.
