Published: August 2019

The comparison between experimental and theoretical heat transfer inside heated vertical channels that dissipate heat from the internal surface with and without internal rings is studied. The experimental setup consists of a circular pipe which is heated electrically by providing constant heat flux on the wall. The theoretical and experimental analysis is conducted in several pipes of same diameter but different lengths. The length of the pipe varies from 450 mm to 850 mm. The length to diameter ratios are taken as L/D = 10, 12.22, 15.56, and 18.89. The value of imposed heat flux varies from 250 to 3340 W/m2. The internal ring thickness varies from 4 mm to 8 mm. separation distance between the internal rings varies from 75mm to 300 mm. The theoretical results are compared with experimental data to ascertain numerical accuracy of the method. The effects of L/D ratio, thickness of internal rings and separation distance on the heat transfer performance are studied. The experimental result is compared with theoretical, theoretical results are found by using ANSYS. In this study theoretical result for wall temperature along the height of tube, fluid temperature at exit of tube are compared with experimental data.

The lifestyle of people who tend to be unhealthy causes a lot of free radicals in the body which can cause various diseases, especially degenerative diseases. To protect the body from attacks by free radicals, the body needs antioxidants such as β-carotene. One of the vegetables containing β-carotene is “wortel” Daucus carota, that is very large in agriculture. The spread of beta carotene from carrots with chemical solvents has been done a lot, but without chemical solvents it has never been done. Based on the color, the content of β-carotene contained in carrots determines the content of beta carotene. The juice obtained by calcium salt was then centrifuged for 3000 rpm 15 minutes. The pellets are separated from the solution, evaporated to dryness, measured at a wavelength of 450-460. Pellets as beta-carotene calcium salts were analyzed by U-HPLC. The next pellet is measured at 460 wavelengths. The levels are determined by high performance liquid chromatography using C18 column and the mobile phase of chloroform-methanol (95:5) with a flow rate of 1 ml / minute at a wavelength of 460 nm. The content of β-carotene in the examination is up to 92,5%. The retention time obtained is 1,903 minutes. The results showed that this method can be used for the withdrawal and determination of β-carotene levels without organic chemical solvents.Pola hidup masyarakat yang cenderung tidak sehat menyebabkan banyak radikal bebas di dalam tubuh yang dapat mengakibatkan berbagai penyakit terutama penyakit degeneratif.

Energy trans-ducting gold nano-particles, with well-being physical, chemical and optical properties for utilization in different types of cancer therapy can be prepared through chemical seed growth reduction method. Gold nano particle is a umbrella term have a variety of size and shape. More regular gold nano-particles can be obtained by reduction of HAuCl4, selection of chemicals and parameters of growth medium are set in accordance with the required category of nano-particles. Nano-particles have longest dimension of 100 nm. Therapeutic treatments like photo-imaging, gene delivery, drug delivery, cell labeling and photo thermal therapy can be done by gold nano particles. They reduce the side effects of conventional therapy due to high target specificity and absorb and scatter specific wavelength of laser. Hyperthermia in cancerous cells is generated without damaging surrounding healthy tissues, cause the cell death by necrosis and apoptosis. The overall morphology of gold nano particles can be characterized by SEM and TEM.
Detection and Characterization of Human Teeth Caries Using 2D Correlation Raman Spectroscopy
Authors: El-Sharkawy Y H 
Published: August 2019

Background: Carious lesions are formed by a complex process of chemical interaction between dental enamel and its environment. They can cause cavities and pain, and are expensive to fix. It is hard to characterize in vivo as a result of environment factors and remineralization by ions in the oral cavity. Objectives: The development of a technique that gives early diagnosis which is non-invasive, is of crucial importance for publichealth. Raman spectroscopy is a technique that can fulfil these requirements. The main goal of this work was to use Raman spectroscopy to differentiate between normal and carious human teethinvivo. The samples used in this study were collected by traditional human teeth. Method: An in vivo Raman spectroscopy system andspecialized fiber optic probe has been designed to obtain spectra from tissue. Theseprobes are filtered to reduce the background signal from the fiber optics and the collection fiberutilizes beam steering to optimize the collection effectiv. Results: In order to detect any demineralization and carious versus sound pit and fissure enamel, the spectral data sets are analyzed by the proposed scheme to demonstrate the utility of generalized 2D correlation spectra. Potential applications of this 2D correlation approach are then explored. The Raman spectra in the normal tissue showed thepresence of vibrational bands in 437.87 cm-1, 581.89 cm-1, 953.89 cm-1 and 1054.73 cm-1 with smaller intensity than in the carious spectra. Image construction from the peak intensity produced chemical maps of apatite concentration.Conclusion: Such two-dimensional correlation spectra emphasize spectral features not readily observable in conventional one-dimensional spectra.No correlation is observed in mode-to-mode intensity fluctuations indicating that the changes inmode intensities are completely independent. Theoreticalcalculations provide convincing evidence that the fluctuationsare not the result of diffusion, orientation or local electromagnetic field gradients but rather are the result of subtle variations ofthe excited-state lifetime, energy and geometry of the molecule and producing a signature response for carious detection.

Background: For preclinical evaluations of radiopharmaceuticals, most studies are carried out on mice. Values of electron specific absorbed fractions (SAF) have had vital role in the assessment of absorbed dose. In past studies, electron specific absorbed fractions were given for limited source target pairs using older reports of human organ compositions.Objective: Electron specific absorbed fraction values for monoenergetic electrons of energies 15, 50, 100, 500, 1000 and 4000 keV were evaluated for the Digimouse voxel phantom incorporated in Monte Carlo code FLUKA. The organ sources considered in this study were lungs, skeleton, heart, bladder, testis, stomach, spleen, pancreas, liver, kidney, adrenal, eye and brain. The considered target organs were lungs, skeleton, heart, bladder, testis, stomach, spleen, pancreas, liver, kidney, adrenal and brain. Eye and brain were considered as target organs only for eye and brain as source organs. From the latest report (International Commission on Radiological Protection ICRP) publication number 110, organ compositions and densities were adopted.Results: The electron specific absorbed fraction values for self-irradiation decreases with increasing electron energy. The electron specific absorbed fraction values for cross-irradiation are also found to be dependent on the electron energy and the geometries of source and target. Organ masses and electron specific absorbed fraction values are presented in tabular form. Conclusion: The results of this study will be useful in evaluating the absorbed dose to various organs of mice similar in size to the present study.

Parametric optimization of the transformation process is a task of improving multiple objectives. In general, no single set of input parameters can provide the best hardness of the metal and the best finish of the surface at the same time. While when using the genetic algorithm proved that it is possible to obtain more than one goal of the function at the same time. In the current research the use of Multi-objective particle swarm optimization (MOPSO) to determine the best hardness of the metal and less roughness of the surface operator at the same time. A mathematical model was also developed to predict the hardness of the metal and surface roughness using Taguchi technology depending on the input variables (cutting speed, cutting depth and feeding rate). Experiments were conducted on a CNC machine in turning carbon steel AISI 1025 using carbide cutting tool. It was found that the most influential factor on the surface roughness is the feeding rate, while the most important effect on the hardness is the cutting speed.
