Prevalence and Predisposing Factors of Diabetic Foot Ulcer Among Adult Patients With Diabetes Mellitus Presenting to Aldarga Diabetic Center, Wadmedani, Sudan 2020 - A Longitudinal Cross Section Study

Objectives: To assess the prevalence of diabetic foot ulcer (DFU) in Wad Medani, Gezira state, Sudan, and the duration of diabetes associated with it.Methods: The study was comprehensively based on primary data obtained via a longitudinal cross-section random sample of 400 patients with diabetic mellitus presenting with Aldarga. The data collection tool was a structured questionnaire. Core questions were on main dimensions: Sociodemographic variables and duration, type of diabetes. Data were analyzed with SPSS program version 20, using descriptive and inferential statistics, namely, frequency tables and graphs, Fisher Chi-square, exact test of association, and logistic regression.Results: The static profile of the participants indicated that genetic background is an important factor in contracting diabetic mellitus. The calculated prevalence rate was 16.6% (17.1% for males and 16.1% for females) with overall probability limits. The analyses of associations indicated that the number of variables in all three dimensions have significant association with the development of DFU. The logistic regression pinpointed two factors with significant odds to develop DFU, namely, the duration of diabetic last fasting blood glucose value and that the duration of the illness is notable. Conclusion: The result suggests extensive awareness programs to control the negative effect of prolonged duration of diabetic’s are necessary especially crucial aspect of monitoring the blood sugar level under strict medical supervision.

Numerical modeling of seismically-induced slope displacements: a comparison between 2D and 3D finite difference models and Newmark-Displacements

<p>The majority of numerical landslide models are designed in 2D. In particular, models based on finite difference methods (FDM) are time-consuming and – as a result – in most cases also cost-intensive. 3D models, therefore, increase the processing time significantly. Another contributing factor to long processing times in the context of modeling of seismically-induced displacements is the fact that mesh grid increments must be small due to the necessity of correct wave propagation through the material. The larger the frequency range of the applied seismic signal should be, the smaller has to be the mesh grid increment. 3D models are, however, considered as more realistic.</p><p>In this work, we present a comprehensive study on numerical 2D and 3D models of the Diezma Landslide, Southern Spain. The Landslide is represented in its shape as it appeared at the time of the main rupture on 18<sup>th</sup> of March in four model layouts: (1) a simplified model in 3D that outlines the landslide body with planar triangular tiles, (2) a longitudinal cross section through this simplified 3D model representing the simplified 2D model, (3) a smooth model in 3D that envelops the landslide body according to the main topographic features, and (4) a longitudinal cross section through this smooth 3D model representing the smooth 2D model.</p><p>On both the simplified and the smooth 2D models, a series of 11 seismic scenarios was applied as SV-waves assuming a source sufficiently far for vertical incidence at the model bottoms in order to produce horizontal shear inside the landslide body with respect to the underlying bedrock. All 11 signals are characterized by different frequency contents, Arias Intensities from 0.1 to 1 m/s, moment magnitudes from 5.0 to 7.0 and peak ground accelerations from 0.8 to 1.2 m/s², and therefore correspond to scenarios that represent the local seismicity in Southern Spain.<br>Because of time-related limitations, only four of these signals were respectively applied to the simplified and smooth 3D model. Newmark-Displacements were calculated using all 11 signals with the classic Newmark-Method that approximates the landslide body in 2D by a rigid block on an inclined plane, and with Newmark’s Empirical Law as spatial information covering the landslide area across the slope in regular intervals.</p><p>We present a systematic comparison of all models and obtained displacements, showing that the Newmark-Methods deliver very similar results to the maximum displacements obtained by FDM. Moreover, we discuss on a particular example that – although seeming more accurate in the layout – smooth models lead not necessarily to realistic results.</p>

Improvement of upsetting process of four-beam workpieces based on computerized and physical modeling

The method of upsetting of large ingots has been investigated in this work. The proposed method consists in upsetting of profiled workpieces with concave faces. An angle of the concave faces was 150°. A relative depth of the concave faces has been varied in range 15%…25% from workpiece's diameter. Strains effective and mean stresses in the longitudinal cross-section of the workpiece with concave faces after upsetting have been determined by FEM. A value of compressive stresses has been determined based on a parameter of the stress state. FEM allowed to find what a rational depth of the concave faces should be, which has to be 15 % from workpiece's diameter. Maximum closing of the internal defect take place for this depth of the concave faces. Results of the FEM have been tested by experimental investigations. It has been established that upsetting of the four-beam workpieces improved a quality of the massive parts.

Sonographic parameters of the pancreas and gall bladder in healthy men from Podillya region of Ukraine of different somatotypes

In this work, we undertook a study of the sonographic parameters of the pancreas and gall bladder in healthy men with different somatotypes. The study-subjects were from the Podillya region of Ukraine. Herein, the majority of gallbladder dimensions (length, thickness, cross-sectional area and volume) in men type-classified as endo-mesomorphic, were significantly higher when compared with men in general and with those of the meso- and ecto-mesomorphic somatotype. Furthermore, the dimensions of the pancreas (width of head and tail length) in mesomorphic males were significantly higher than that of endo-mesomorphic males. The rest of the studied parameters (length, longitudinal cross section area of the gall bladder, the thickness of the head, body and head length, the width of the body and tail of the pancreas) in men of the different somatotypes have no significant differences.

Microstructures of Graphite/Copper Composites Prepared by Mechanical Milling and Hot Extrusion

To obtain graphite/copper composites with excellent microstructures, preparation process including mechanical milling, compact compressing, vacuum hot pressed sintering and hot extrusion had been put forward. Effect of milling time and hot extrusion on microstructures of composites had been analyzed and investigated by optical microscope. The results show that after mechanical milling, refined and uniform distributed graphite phase could optimize microstructures of composites. While increasing extrusion ratio, graphite particles and graphite fibers in longitudinal cross-section of composites could be refined effectively. Under of the same conditions, grain size of copper in graphite/copper composites is larger when raising extrusion temperature.

Teat anatomy affects requirements for udder preparation in Mediterranean buffaloes

The present study was conducted to assess the interrelation between teat anatomy and machine milking in dairy buffaloes raised in Switzerland. A 3-min pre-stimulation induced milk ejection before cluster attachment in most cases and caused an optimal milk removal during machine milking. In an additional experiment, longitudinal cross-section ultrasound was obtained before and after a 3-min pre-stimulation. Teat wall thickness, teat diameter, cisternal diameter and teat canal length were evaluated. It was observed that 3-min pre-stimulation dramatically reduced teat canal length whereas all the other anatomical parameters remained unchanged. The vacuum needed to open the teat canal was also measured before and after a 3-min pre-stimulation by using a special teat cup with only the mouthpiece of the liner remaining on the top of the teat cup (no liner, no pulsation). Without pre-stimulation but after wetting the teat canal by stripping one squirt of milk out of the teat, no milk could be withdrawn with a vacuum up to 39 kPa. However, after pre-stimulation, milk flow occurred in all buffaloes at a vacuum between 16 and 38 kPa. In the last experiment, the teat tissue was examined in slaughtered buffaloes and compared with teat tissue of cows. No difference was noted in histological sections and teat canal length was similar in cows and buffaloes. Proximal to the teat canal, the teat did not pass into an open cistern but the lumen was collapsed. In conclusion, buffaloes need to be well pre-stimulated because the tissue above the teat canal provides additional teat closure before milk ejection. Therefore, milk can only be obtained after pre-stimulation.
