Granulation Mechanism

Roller mechanism and conveyor are important components in sulfur granulation system. This paper presents the method to design roller mechanism to apply two goals: create a continuous pressure for a regular granulation on steel conveyor. There are also granulation mechanism and maintain temperature not to stuck and solidify of sulfur in the supplying pile. Moreover, this paper shows the solution to design steel conveyor and filtering system including with temperature sensor which ensure the decreasing of temperature over the length of steel bell. This will help the granulation of sulfur with the right size and shape.

Introduction: The aim of the study was to establish normal reference values obtained by fetal speckle tracking analysis of the fetal heart between 17-24 weeks of gestation among Thai fetuses and compare the nomograms with previous studies. Methods: The 4-chamber view of the fetal heart in 79 normal fetuses was analyzed by speckle tracking analysis to determine the best-fit regression model. The 95% reference intervals and Z-score equations of fetal cardiac parameters were computed. Results: The end-diastolic length, width, area, and circumference of the 4-chamber view (4CV) as well as the ventricular end-diastolic length, 24-segment widths, and area were all increased as a function of gestational age (GA) and 5 fetal biometric parameters. In contrast, the global sphericity index (SI), 24-segment SI, and right ventricle/left ventricle width and area ratios did not change with GA or fetal biometric measurements. There were few differences in Z-score reference ranges of fetal cardiac measurements between the current study and previous studies conducted in different patient populations. Conclusion: Our study provided z-score and corresponding centile calculators, 5th and 95th centile reference tables, and corresponding graphs for evaluating the size and shape of the 4CV and the right and left ventricles using 6 independent variables between 17 and 24 weeks of gestation. These results provide normal reference ranges for future studies of fetuses with pathologies that may alter the size and shape of the 4-chamber view and ventricles.

Lack of communication can be seen in many aspects, such as public health, and recycling. We found that in public health people suffer from lack of facilities and it may lead to death, but building new hospitals is not the right solution, but improved communication is. To solve both problems with a simple solution, the Internet of Things (IoT) had to be involved. So, we proposed a solution, which is a WHD (wearable health device) that measures temperature and heart rate for the patient and compares them to a database, it consists of Arduino Nano wired to both LM35 temperature sensor and pulse sensor. The readings are displayed on an OLED screen, as well as on a mobile application called ThingView. If the readings are abnormal, an action would be taken either to contact a relative or the ambulance, depending on its severity. It would decrease the trips to hospitals. We have tested for the device's efficiency and sensor calibration, and the results were promising. The competence of the pulse sensor is very high as its relative error is ±0.07. The temperature sensor (LM35) has very low relative error which is ±0.00356. The final cost was computed to be $26.5.

SummaryThis case report describes derangement of the numbered carpal bones resulting in a valgal growth deformity in the right carpus of a seven-month-old dog. Radiographic assessment of the right carpus revealed abnormalities in the size and shape of the numbered carpal bones and carpal valgus. Surgical correction of the growth deformity was planned by partial carpal arthrodesis; however medial collateral laxity associated with the carpal valgus necessitated a pancarpal arthrodesis to achieve correct limb alignment.

Background: Morphological and geometric differences between male and female feet can be the decisive factor of whether well-fitting, functional, and comfortable footwear is available for both men and women. Methods: Optical scans, plaster wrap casts, and a set of manual measurements from the right feet of 51 female participants, aged 20 to 59 years (32 ± 10.2 years), and 39 male participants, aged 22 to 71 years (47.1 ± 12.1 years), were taken to determine which parameters were the most significant in characterizing pedal geometry and which had the largest difference between male and female feet. Results: Analysis showed that the heel-to-ball length (ball length) of the male participants’ feet (181.5 mm) was significantly longer, on average, than that of the female participants’ feet (165.0 mm). The width of the male paticipants’ feet at the ball, instep, and heel regions, as well as the ball circumference, normalized by the ball length, were all significantly larger on average, than the female test participants’ feet. However, toe region, instep, and medial and lateral malleoli heights were larger, on average, for the female participants than for the male. The results show that female feet differ in size and shape from male feet and are not algebraically scaled, smaller versions of male feet, as is often assumed. Conclusions: The study shows that the average male participants’ feet are longer than that of the female participants’ feet, while the female feet are relatively narrower but higher than those of the male participants.

Cocoa Fermentation

Automatic cocoa fermentation design is expected to facilitate the work of cocoa farmers during the process of reversing and stirring cocoa fermentation based on the right temperature. Fermentation process is of course done in a box or sack so that chocolate quickly produces heat and is cemented. However, in certain  conditions,  especially  when  in  sacks  there  are  often  obstacles  in  the stirring process. Often the fermented chocolate experiences weathering or moldyness  due  to  the  uneven  reversal  that  causes chocolate  to  clot,  causing weathering or moldiness and produce an unpleasant odor and unattractive color on the cocoa beans. To overcome this problem a tool that automatically can turn or stir the cocoa beans evenly. This device is controlled by Arduino Uno R3 with a sensor that is an LM35 temperature sensor and has an LCD output and DC motor. This tool uses Relay to adjust the delay when driving a DC motor. The working principle of this tool, when the LM35 temperature sensor receives heat conditions on the cocoa beans, the LCD will display the condition of the temperature while the relay will instruct the DC motor to move the Cocoa Fermentation rail rotating left or right. The purpose of making this tool is to create a tool that can help alleviate the work of cocoa farmers in cocoa bean stirring activities at the time of cocoa bean fermentation controlled by Arduino.

Abstract: Mandibular size and shape are important information especially in terms to figure out the right diagnosis and the type of treatment a patient should have. Human mandible is a key factor for occlusion adjustment, meanwhile maxilla is following the mandible’s position. Several studies show that the stability of mandibular shape and size determines the success of one’s treatment. Each ethnic group has a particular skeletal pattern as well as shape and size of mandible. This study was aimed to obtain the average size and shape of mandibles among local Papuans. This was a descriptive observational study with a cross-sectional design. Samples were obtained by using purposive sampling method. There were 35 local Papuans aged 18-25 years as subjects. Data were obtained by molding the subject’s mandible, therefore, each subject produced a study model. The study model was measured in sagittal (length) and transversal (width) views based on Raberin method. The results showed that the average lengths of local Papuans’ mandibular size in sagittal view (L31, L61, and L71 in a row) were 6.143; 26.463; and 43.743 mm meanwhile the average widths of local Papuans’ mandibular size (L33, L66, and L77 in a row) were 30.857; 50.971; and 60.971 mm. The mandibular shape of most local Papuans was mid shape (45.8%) meanwhile the least shape of them was pointed (5.7%)Keywords: dental arch size, dental arch shape, mandibular, local Papuan Abstrak: Ukuran dan bentuk lengkung gigi rahang bawah sangat diperlukan dalam menentukan diagnosis dan rencana perawatan yang tepat dalam bidang ortodontik karena rahang bawah merupakan faktor stabilitas oklusi, sedangkan rahang atas menyesuaikan pada rahang bawah. Beberapa peneliti menyatakan bahwa kestabilan bentuk dan ukuran lengkung gigi rahang bawah merupakan faktor stabilitas dari hasil perawatan.

In the vascular cambium of Platanus Z and S domains appear in the course of formation of the first annual ring. Their arrangement is connected with the division of the stem into nodes and internodes. In each node a domain of Z and of S type occurs. The longitudinal boundaries between them run along the middle leaf trace and on its opposite side, and the transverse boundaries lie in the nodes. Z-type domains are found on the right below the base of the nearest upper leaf, and S-type domains on the left. As the young cambium forms further rings, the size and shape of the domains changes.

Phlebotomus (Paraphlebotomus) sergenti Parrot, 1917, the proven vector of Leishmania tropica Wright, 1903, the causative agent of anthroponotic cutaneous leishmaniasis, is widely distributed in Morocco. Previous works using molecular markers (ITS2 rDNA and Cyt b mtDNA) have hy-pothesized the existence of multiple closely related populations of sandfly species (cryptic species) that would exhibit distinct vectorial capacities. In this work, descriptive characteristics of wings (size and shape of the right and left wings) were measured in samples collected from fourteen sta-tions in central Morocco. These analyses support the existence of distinct P. sergenti populations, enlightening significant phenotypic variations of P. sergenti’s wings, regarding their size and shape, depending on geographic origin. In addition, geomorphometric analyses of wing’s length, centroid size, alpha, and beta distances allowed clear discrimination of P. sergenti sub-populations. These data pinpoint the adaptative ability of P. sergenti to local environmental conditions. Additional studies are now required to further shed light on the genetic structure of P. sergenti populations in Morocco.
