Rancangan Kontrol Gerakan Sample Changer Berbasis Usb Pada Perangkat Radioimmunoassay-ria Ip8

A DESIGN OF USB BASED SAMPLE CHANGER MOVEMENT CONTROLLER ON THE IP8 RADIOIMMUNOASSAY-RIA EQUIPMENT. A sample changer movement controller system for the IP8 RIA equipment has been designed. The Radioimmunoassay equipment is commonly used to determine hormone or vitamin concentrations using nuclear techniques. The Ip8 RIA equipment is designed for automatic measurements on multiple samples using one well-type NaI(Tl) detector through sample changer control. The control is performed using mechanical system and software-controlled electronic system. When the motor is turned on and the sample tube is above the detector tube, the mechanical system rotates 14,4 degrees to slide a sample tube, then moves down 7 cm to insert the sample tube into the detector tube, then removes it from the detector tube by moving up 7 cm, then repeat this sequence until the motor is turned off. The electronic system is designed to turn the motor off using limit switches when the sample is inside the detector, to allow counting to proceed, and to turn the motor on after counting is completed, to allow the mechanical system to replace the sample tube inside the detector with the next sample tube. The design of the sample movement controller is discussed in detail in this paper. The result of the design process are schematics and production-ready PCB layout. It is concluded that this design can be applied to improve the performance of the IP8 RIA equipment. Rancangan kontrol gerakan sample changer BERBASIS USB pada perangkat Radioimmunoassay-RIA IP8. Telah dilakukan rancangan sistem pengatur gerakan sample changer pada perangkat RIA IP8. Perangkat radioimmunoassay biasa digunakan untuk mengetahui kadar hormon atau vitamin menggunakan teknik nuklir. Perangkat RIA IP8 dirancang untuk mengukur sampel yang banyak secara automatis melalui pengaturan sampel changer dengan satu detektor NaI(Tl) tipe sumur. Pengaturan ini dilakukan dengan sistem mekanik dan sistem elektronik yang dikontrol melalui perangkat lunak. Cara kerja sistem mekanik adalah, jika posisi tabung sampel berada di atas dan motor dihidupkan, maka gerakannya memutar horisontal 14,4 derajat untuk menggeser tabung kemudian turun 7 cm untuk memasukkan tabung sampel ke dalam detektor, kemudian naik lagi 7 cm untuk mengeluarkan tabung sampel kemudian berulang memutar kembali sampai motor dimatikan. Pada sistem elektronik dirancang guna menghentikan motor melalui limit switch jika posisi sampel berada di bawah (di dalam detektor) untuk kemudian dicacah dan motor akan dihidupkan kembali secara software jika pencacahan telah selesai, sehingga sampel akan naik dan bergeser mengganti sampel berikutnya untuk dicacah. Rancangan kontrol gerakan sampel tersebut dibahas secara detail pada makalah ini. Hasil rancangan modul ini berupa gambar skematik dan gambar PCB yang siap dicetak. Disimpulkan bahwa hasil rancangan ini dapat diterapkan untuk memperbaiki kinerja perangkat RIA IP8

Single channel magnetic induction spectroscopy technique for fetal acidosis detection

Current fetal acidosis diagnosis needs an invasive measurement which required a doctor to puncture fetal scalp to acquire blood pH. This method introduced risk to the fetal which fetal scalp may bruise and infected. This paper discusses a noninvasive method employing a single channel magnetic induction spectroscopy technique as an alternative method to diagnose acidosis in fetal without puncturing the fetal scalp. The studies are based on numerical simulation models to investigate the most feasible sensor coil that is sensitive and effective to be implemented in hardware setup as the shape of coil influences directly the sensing performance of the magnetic induction spectroscopy system. The study has found that the circular coil is more sensitive than linear coil. The system tested with different pH samples to mimic the blood pH value. The result is very promising with good correlation approaching 1 has been achieved. Therefore, magnetic induction spectroscopy technique has good opportunity to be applied as an alternative method to detect acidosis in the fetal with circular coil is performed as the best sensing coils for MIS hardware

A cross-sectional study on the co-occurrence of infectious diseases, malnutrition and cardio-metabolic risk factors

In sub-Saharan Africa, infectious diseases and malnutrition constitute the main health problems in children, while adolescents and adults are increasingly facing cardio-metabolic conditions. Among adolescents as the largest population group in this region, we investigated the co-occurrence of infectious diseases, malnutrition and cardio-metabolic risk factors (CRFs), and evaluated demographic, socio-economic and medical risk factors for these entities. In a cross-sectional study among 188 adolescents in rural Ghana, malarial infection, common infectious diseases and Body Mass Index were assessed. We measured ferritin, C-reactive protein, retinol, fasting glucose and blood pressure. Socio-demographic data were documented. We analyzed the proportions (95% confidence interval, CI) and the co-occurrence of infectious diseases (malaria, other common diseases), malnutrition (underweight, stunting, iron deficiency, vitamin A deficiency [VAD]), and CRFs (overweight, obesity, impaired fasting glucose, hypertension). In logistic regression, odds ratios (OR) and 95% CIs were calculated for the associations with socio- demographic factors. In this Ghanaian population (age range, 14.4–15.5 years; males, 50%), the proportions were for infectious diseases 45% (95% CI: 38–52%), for malnutrition 50% (43–57%) and for CRFs 16% (11–21%). Infectious diseases and malnutrition frequently co-existed (28%; 21–34%). Specifically, VAD increased the odds of non-malarial infectious diseases 3-fold (95% CI: 1.03, 10.19). Overlap of CRFs with infectious diseases (6%; 2–9%) or with malnutrition (7%; 3–11%) was also present. Male gender and low socio-economic status increased the odds of infectious diseases and malnutrition, respectively. Malarial infection, chronic malnutrition and VAD remain the predominant health problems among these Ghanaian adolescents. Investigating the relationships with evolving CRFs is warranted

Charged Higgs boson contribution to νˉe−e\bar{\nu}_e-e scattering from low to ultrahigh energy in Higgs triplet model

We study the $\bar{\nu}_e-e$ scattering from low to ultrahigh energy in the framework of Higgs Triplet Model (HTM). We add the contribution of charged Higgs boson exchange to the total cross section of the scattering. We obtain the upper bound $h_{ee}/M_{H^\pm}\lesssim2.8\times10^{-3}GeV^{-1}$ in this process from low energy experiment. We show that by using the upper bound obtained, the charged Higgs contribution can give enhancements to the total cross section with respect to the SM prediction up to 5.16% at $E\leq10^{14}$ eV and maximum at $s\approx M_{H^\pm}^2$ and would help to determine the feasibility experiments to discriminate between SM and HTM at current available facilities.Comment: 6 pages, 6 figure

Nuclear Transparency to Intermediate-Energy Protons

Nuclear transparency in the (e,e'p) reaction for 135 < Tp < 800 MeV is investigated using the distorted wave approximation. Calculations using density-dependent effective interactions are compared with phenomenological optical potentials. Nuclear transparency is well correlated with proton absorption and neutron total cross sections. For Tp < 300 MeV there is considerable sensitivity to the choice of optical model, with the empirical effective interaction providing the best agreement with transparency data. For Tp > 300 MeV there is much less difference between optical models, but the calculations substantially underpredict transparency data and the discrepancy increases with A. The differences between Glauber and optical model calculations are related to their respective definitions of the semi-inclusive cross section. By using a more inclusive summation over final states the Glauber model emphasizes nucleon-nucleon inelasticity, whereas with a more restrictive summation the optical model emphasizes nucleon-nucleus inelasticity; experimental definitions of the semi-inclusive cross section lie between these extremes.Comment: uuencoded gz-compressed tar file containing revtex and bbl files and 5 postscript figures, totalling 31 pages.

Localization and prediction of malignant potential in recurrent pheochromocytoma/paraganglioma (PCC/PGL) using 18F-FDG PET/CT

Background: To our knowledge, data are lacking on the role of 18F-FDG PET/CT in the localization and prediction of neuroendocrine tumors, in particular the pheochromocytoma/paraganglioma (PCC/PGL) group. Purpose: To evaluate the role of 18F-FDG PET/CT in localizing and predicting the malignant potential of PCC/PGL. Material and Methods: Twenty-three consecutive patients with a history of PCC/PGL, presenting with symptoms related to catecholamine excess, underwent 18F-FDG PET/CT. Final confirmation of the diagnosis was made using the composite references. PET/CT findings were analyzed on a per-lesion basis and a per-patient basis. Tumor SUVmax was analyzed to predict the dichotomization of patient endpoints for the local disease and metastatic groups. Results: We investigated 23 patients (10 men, 13 women) with a mean age of 46.43±3.70 years. Serum catecholamine levels were elevated in 82.60% of these patients. There were 136 sites (mean SUVmax: 16.39±3.47) of validated disease recurrence. The overall sensitivities for diagnostic CT, FDG PET, and FDG PET/CT were 86.02%, 87.50%, and 98.59%, respectively. Based on the composite references, 39.10% of patients had local disease. There were significant differences in the SUVmax distribution between the local disease and metastatic groups; a significant correlation was noted when a SUVmax cut-off was set at 9.2 (P<0.05). Conclusion: In recurrent PCC/PGL, diagnostic 18F-FDG PET/CT is a superior tool in the localization of recurrent tumors. Tumor SUVmax is a potentially useful predictor of malignant tumor potential
