Palm wine has long been the traditional wine of choice for most people during festive periods and social activities. This research work was done to determine the effect of ingested fresh palm wine on pupil diameter and amplitude of accommodation in young adults. Fifty (50) young adults aged between 18-35 years with a mean age of 23.46(±2.54) and weight ranging from 45-80kg with mean weight of 61.18(±8.00) volunteered for this work. The volunteers had normal body mass index (BMI) of between 18.5 and 25kg/m2. Pupil diameter in millimeters (mm) and Amplitude of Accommodation (AA) in diopters (D) were measured before and after 30 minutes, 60 minutes and 90 minutes intake of 330ml of fresh palm wine containing 5.1% alcohol at the time it was consumed. Physicochemical analysis of the palm wine showed the presence of Solids, Sugar, Ascorbic acid (Vitamin C) while microbiological analysis showed the presence of yeasts. Its pH at the time was 6.20. Statistical analysis with SPSS version 21 showed that the mean pupil diameter before intake of fresh palm wine was 3.80(±0.72) and mean value 30 minutes, 60 minutes and 90 minutes after intake of fresh palm wine were 3.30(±0.61), 3.48(±0.75) and 4.20(±0.64) respectively. The mean Amplitude of accommodation before intake of fresh palm wine was 12.16(±3.66) and mean value 30 minutes, 60 minutes and 90 minutes after intake of fresh palm wine were 13.86(±3.31), 10.19(±2.47) and 9.16(±2.12) respectively. The result obtained was statistically significant using one way ANOVA at 95% confidence interval and 0.05 level of significance; P(0.00) ˂0.05. The mean difference was significant at the 0.05 level. This study showed that fresh palm wine interfered with visual functions as increased pupil size and changes in AA were observed. Key words: Fresh palm wine, pupil diameter, amplitude of accommodation.

This study is aimed to determine the microbiological and chemical quality of Feta cheeses which are consumed in Van city center. In this study, a total of 50 Feta cheese samples were used as material. At the result of microbiological analysis of Feta cheeses, the mean number of total aerobic mesophilic bacteria, lactic acid bacteria, coliform, Escherichia coli, micrococcus/staphylococcus, coagulase positive Staphylococcus aureus, Clostridium perfringens, Enterobacteriaceae, yeast and mold were found as 5.49 log cfu/g, 5.20 log cfu/g, 0.78 log cfu/g, 0.10 log cfu/g, 0.58 log cfu/g, 0.53 log cfu/g, 0.08 log cfu/g, 0.96 log cfu/g, 5.18 log cfu/g, respectively. At the result of chemical analysis, the mean value of pH, titratable acidity, dry matter, fat, fat in dry matter, salt and salt in dry matter were found as 4.38, 1.41% LA, 41.21%, 18.12%, 44.18%, 8.36% and 20.42%, respectively. All of the samples were found conforming to the standards in terms of titratable acidity. On the other hand, 8%, 52% and 100% of samples were found unsuitable in terms of coagulase positive S. aureus, pH and salt in dry matter, respectively. As a result, it was concluded that Feta cheeses examined are inadequate in terms of microbiological and chemical quality and they could pose a risk to producers and consumers. The implementation of the HACCP system based on GMP at all stages of the food chain will play an active role for food safety, public health and the protection of consumer rights.

1. Resting membrane potential (Vmp), input resistance (Rn), rheobase (Irh), and after hyperpolarization duration (AHPdur) and amplitude (AHPamp) were measured in 38 phrenic motoneurons of anesthetized, paralyzed, and artificially ventilated cats during hypocapnic apnea. The mean +/- SD and range of values for these variables were as follows: Vmp, -68 +/- 5mV (range: -60 to -82); Rn, 1.3 +/- 0.6 M omega (0.6-2.4); Irh, 9.7 +/- 5 nA (2-20); AHPdur, 68 +/- 19 ms (37-134); AHPamp, 3.3 +/- 1.8 mV (1.0-8.5). In 31 motoneurons, the membrane potential level at which firing occurred (Vthr) during intracellular current injection was measured. The mean value of Vthr was -58 +/- 3 mV (range: -52 to -64). 2. A histogram of Rn revealed a bimodal distribution. Also a plot of Irh against Rn showed a grouping of the motoneurons into two subpopulations: 1) low-Rn and high-Irh cells, called type L neurons, and 2) high-Rn, low-Irh cells, called type H neurons. The overall negative linear correlation between Irh and Rn (r = -0.85; P less than 0.0001) resulted from this grouping rather than from a strictly linear relation between these two variables. 3. Electrical properties were compared for type L (n = 20) and type H (n = 18) phrenic motoneurons. The following mean values were found for each group, respectively: Rn, 0.8 and 1.8 M omega; Irh, 13.7 and 5.3 nA; AHPdur, 58 and 79 ms; AHPamp, 2.4 and 4.4 mV. All differences were significant (t test, P less than 0.001). Mean Vthr was the same for the two groups. 4. Comparison of these data with those available for lumbosacral motoneurons revealed that almost all investigated electrical properties of type L and type H phrenic motoneurons are similar to the analogous properties of type F (fast twitch) and type S (slow twitch) lumbosacral motoneurons, respectively. The apparent exception is the lower mean value of Irh for type L phrenic motoneurons compared with type F lumbosacral motoneurons. 5. For 13 cells, membrane potential was continuously monitored while spontaneous respiratory activity was restored by increasing CO2. It was found that at approximately the same end-tidal CO2 (about 7%) and a similar end-expiratory mean membrane potential level (approximately -70 mV), mean amplitude of peak inspiratory synaptic depolarization was higher in type H motoneurons (8.8 mV, n = 5) than in type L (2.9 mV, n = 8; P less than 0.001).(ABSTRACT TRUNCATED AT 400 WORDS)

A noninvasive method was developed for measuring the digital arterial pressure and the compliance by using a fingertip pneumoplethysmograph and a pneumatic cuff. The compliance (C) of the digital artery was obtained from the peak amplitude of the volume pulse wave (deltaVp-a) under the effect of the cuff pressure (Po-a) by the equation: C = deltavp-a/(Ps - P-o-a) during the dicrotic phase defined in this study. The normal mean value was 11.37 +/- 0.59 X 10(-5) cm3/mmHg. On lowering of the cuff pressure, the moment when the deltaVp value becomes positive is regarded as the systolic pressure (Ps). At the end of the dicrotic phase, the mean amplitude (deltaVss') of the pulse wave during one pulse cycle (SS') and the ratios (deltaVss'/deltaVsd), where deltaVsd is the mean amplitude of the wave during the systolic period (SD), of successive waves after a particular wave fail to increase at the same rate when the cuff pressure decreased below the diastolic pressure. The cuff pressure corresponding to this particular wave is regarded as the diastolic pressure (Pd). The mean value of the mean digital pressure of normotensive subjects was 80.6 +/- 1.2 mmHg.

The conformable derivative and its properties have been recently introduced. In this research work, we propose and prove some new results on the conformable calculus. By using the definitions and results on conformable derivatives of higher order, we generalize the theorems of the mean value which follow the same argument as in the classical calculus. The value of conformable Taylor remainder is obtained through the generalized conformable theorem of the mean value. Finally, we introduce the conformable version of two interesting results of classical multivariable calculus via the conformable formula of finite increments.

The aim of this research work was to reveal specific peculiarities of young swimmers training, taking into account their pubescence in terms of the long-term training concept. During the research it was defined that methodological support of spots training for a long-term period should contain not only prognostic model of prospective results achievement. It also should analyze individual peculiarities of pubertal period. During the research we used the official results of competitions protocols, the results of general and special physical readiness tests, resume of the leading swimming coaches. For statistical data handling we used quantitative variables, presented in a form ± of a standard error of the mean value (М ± m). The results were considered as statistically significant in terms of р < 0,05. Correlation analysis is realized using Pearson correlation coefficient. The held research helped to define typical characteristics of pubertal period in teen-agers swimmers, timely correct the training process. It was stated that athletes adaptation to the training and competitive loads in pubertal period was characterized by different degree of sports results increase and correlated with the intensity of hormonal changes. The boys with distinct features of pubertal period were the leaders at short distances, but showed coordinating abilities decrease. The athletes, whose somatic-gender changes didn’t have extreme indices or had prolonged duration, showed stable sports results increase mainly at long distances.

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.
