目前,冷冻外科仅以直觉和经验为基础而进行,故其临床应用受到限制。它在治疗表浅恶性肿瘤和良性血管瘤上虽属有效,但其主要困难在于难以确定冷冻区的范围。为了提高冷冻外科的实用价值,此实验旨在:(1)确定是否可以应用一个特制的测温器来确定肿瘤的范围;(2)提供一个生物物理的数学公式来预测冷冻的深度;(3)探讨是否可用本实验中所使用的测温器,为冷冻外科的治疗提供一个更确切的诊断依据;(4)应用这种测温装置作为冷冻外科对恶性肿瘤的临床诊断与治疗的辅助装置。

Background: The prevalence of diabetes in Pakistan is 11.45%. The reported prevalence of diabetic foot ulceration in Pakistan is between 4% and 10%, with the amputation rate of 8% - 21%. Peripheral neuropathy and vasculopathy are main underlying cause of diabetic foot ulcers. Methodology: It was a cross-sectional non-interventional cohort study where all newly diagnosed treatment naïve type 2 diabetic patients were enrolled. Peripheral neuropathy and vasculopathy were detected by Michigan neuropathy screening instrument (MNSI) and ankle brachial index (ABI) respectively. Risk factors for peripheral neuropathy and vasculopathy were determined by univariate and multivariate logistic regression analysis. Statistical significance was considered with P value of Result: Fifty seven patients (37.7%) had early neuropathy with MNSI score of 3.3 ± 0.4. Thirty seven patients (20.6%) had vasculopathy with ABI score of 0.76 ± 0.11. Age (Odd ratio 1.07 (1.02 - 1.11), p 0.003), duration of symptoms (Odd ratio 1.11 95% CI: 1.05 - 1.17, p ≤ 0.001), high HbA1C % (Odd ratio 1.94 95% CI: 1.54 - 2.45, P ≤ 0.001), albumin creatinine ratio (Odd ratio 1.01, 95% CI: 1.00 - 1.01, P ≤ 0.001 ) and cholesterol level (Odd ratio 1.01 95% CI: 1.01 - 1.02, p = 0.001) were found as risk factors for early neuropathy and vasculopathy. Conclusion: Peripheral neuropathy and vasculopathy are frequently reported complications among newly diagnosed treatment naïve patients of type 2 DM. Age, duration of symptoms prior to diagnosis, metabolic parameters like raised HbA1C, hyperlipidemia and spot random albumin creatinine ratio are found to be risk factors for both peripheral neuropathy and vasculopathy.

A solid polymer electrolyte (SPE) films consist-ing of polyethylene oxide (PEO), 50% epoxi-dized natural rubber (ENR50) and liCF3SO3 with various compositions of PEO-ENR50 and vari-ous weight percentage of liCF3SO3 were pre-pared by solution casting technique. The poly-mer electrolyte films were characterized using DSC, XRD and AC impedance spectroscopy. The SPE with the PEO-ENR50 composition of 70-30 shows the highest conductivity of 4.2 × 10-5 Scm-1 at the 15 wt.% of liCF3SO3 compared with the other composition of PEO/ENR50. This composition was then chosen to investigate the effect of liCF3SO3 on the thermal property, structure and conductivity of the electrolyte. The highest room temperature conductivity of 1.4 × 10-4 Scm-1 was achieved at 20 wt.% of liCF3SO3. The conductivity result is supported by the DSC and XRD analysis which showed the semi- crystalline nature of PEO turning to amor-phous state due to the increase in liCF3SO3 content.

Validity of CA-Markov in land use and cover change simulation was investigated at the langat Basin, Selangor, Malaysia. CA-Markov validation was performed using validation metrics, allocation disagreement, quantity disagreement, and figure of merit in a three-dimensional space. The figure of merit, quantity error, and allocation error for total landscape simulation using the 1990-1997 calibration data were 5.62%, 3.53%, and 6.13%, respectively. CA-Markov showed a poor performance for land use and cover change simulation due to uncertainties in the source data, the model, and future land use and cover change processes in the study area.

The flash technique of thermal diffusivity measurement applied to composite materials is dependent upon the success at deriving and solving the associated heat diffusion equation for the particular boundary problems of the experiment. Orthogonal expansion technique and the Green’s function approach are easier and straight forward for deriving and solving such equations, but the solutions converge very slowly for small times and hence cannot be used for numerical calculations. The laplace transformation technique on the other hand has advantage of allowing for the making of small time approximation in order to obtain solutions that are very rapidly convergent. The principle difficulty of this technique is in the inversion of the resulting transform from s to t domain. Inversion by contour integration requires a lot of mastery in integral calculus and the simplest method is therefore to look up for the transform in the standard laplace conversion table. At first look not all subsidiary equations can be converted using the laplace transform conversion table;in this work however, we present the mathematical analysis by means of which analytical solutions to heat diffusion problem in composite media;hitherto only transformed via contour integration, is obtained directly from the laplace transform conversion tables.

High energy requirement of vapor compression cooling systems in addition to harmful refrigerants further necessitates the increasing need for more reliable, flexible, environmentally friendly, and cost-efficient cooling systems options. Adsorption cooling technology could be a better option in terms of huge energy saving potential, Carbon emission reduction, flexibility, and waste heat utilization. There are, however, some setbacks that hindered adsorption cooling technology from real mass production and commercialization. This work seeks to study, evaluate and compare the energy requirement and coefficient of performance of solar-powered adsorption cooling system (as an application of renewable energy) in relation to vapor compression system. Adsorbate/adsorbent equilibrium test (using a test rig) was used to predict the performance of thermal driven adsorption cooling system using methanol/activated carbon (as adsorbate/adsorbent pair) in relation to similar data obtained from laboratory vapor compression refrigeration test rig (same mass of refrigerant). For the adsorption cooling system and vapor compression system, the energy requirements were found to be 1913.57 kJ and 8932.02 kJ while the coefficient of performance (COP)s were found to be 0.39 and 1.2 respectively. Presumably, the adsorption cooling system has an energy requirement that could be powered by direct solar thermal heating using a flat plate collector, however, the COP is relatively lower indicating lower cooling capacity, and hence takes a longer period of time to overcome the same cooling load as vapor compression system. It is recommended among other things that research should focus on developing better adsorbate/adsorbent pairs for an increased adsorption/desorption time.

Borotellurite glasses show potential application in nonlinear devices and are of interesting materials to he studied due to their low melting points, high refractive index, high dielectric constant and good infrared transmission. In this work, a systematic series of horotellurite glasses （B2O3）1-x （TeO2）x with x=0.6 - 0.80 were synthesized by rapid quenching. longitudinal and shear ultrasonic velocities were measured in each horotellurite glass samples at room temperature and at 5 MHz frequency. Ultrasonic measurements were carried out by using the MBS8000 Ultrasonic Data Acquisition System. Densities of the glass samples were measured using displacement method while acetone was used as immersion liquid. Elastic constants were calculated as well as Poisson＇s ratio, Dehye temperature, softening temperatures and microhardness for all glass samples. Makishima-Mackenzie theory and bond compression model were applied to compare between the experimental elastic moduli data and the calculated theoretically.
