Published: June 2020

ABSTRAKMineralisasi uranium (U) di Sektor Lembah Hitam pada batuan metalanau dan metapelit sekistosan berasosiasi dengan mineral pirit, pirhotit, magnetit, molibdenit, turmalin, dan kuarsa. Kehadiran mineral U ditandai dengan nilai radiometri batuan yang mencapai 15.000 c/s. Estimasi cepat kadar U adalah menggunakan perhitungan gamma ray hasil logging gross-count gamma lubang bor LH-01. Penelitian ini bertujuan untuk mendapatkan validitas dan reliabilitas data estimasi kadar U. Hasil estimasi kadar U logging disebandingkan dengan analisis geokimia untuk mendapatkan faktor koreksi (Fk). Analisis geokimia menggunakan metode X-Ray Fluorescence (XRF) pada sampel batuan terpilih di interval kedalaman yang mewakili batuan dan mineralisasi di lubang tersebut. Estimasi kadar U di kedalaman 8,80–9,81 m berdasarkan gross-count gamma ray menunjukkan nilai kadar 456 ppm eU, sementara analisis XRF menunjukkan rerata kadar 177 ppm U. Nilai faktor koreksi (Fk) yang didapatkan dari estimasi kadar di kedalaman 8,80–9,81 m adalah 0,388. Nilai tersebut menunjukkan validitas dan reliabilitas data estimasi yang digunakan rendah. Kesebandingan estimasi kadar U dipengaruhi oleh beberapa faktor, antara lain: sistem logging gross-count gamma ray, ketidaksetimbangan uranium, ukuran sampel, dan unsur radioaktif lainnya. Untuk meningkatkan validitas dan reliabilitas data estimasi, maka diperlukan penambahan sampel analisis XRF dengan mempertimbangkan lingkar dan interval kedalaman lubang bor. ABSTRACTUranium (U) mineralisation in Lembah Hitam Sector in metasilt and schistossic metapellite rocks was assosiated with pyrite, pyrhotite, magnetite, molibdenite, tourmaline, and quartz minerals. The existence of U mineral was marked from its radiometric value reaching 15,000 c/s. The faster way to estimate U grade is using gamma-ray values calculation from gross-count gamma logging at borehole LH-01. The research is aimed to obtain the validity and reliablility of U grade estimating data. The logging estimation result then compared with geochemical analysis to obtain the correction factor (Fk). Geochemical analysis is using X-Ray Fluorescence (XRF) method on selected rock samples represent rock and mineralisastion depth interval inside the borehole. The result of uranium grade estimation using gross-count gamma ray calculation in depth 8.80–9.81 m is 456 eU while based on XRF analysis, the result is 177 ppm U. The correction factor (Fk), obtained from grade estimation at 8.80–9.81 m depth is 0.388. The value indicates that the validity and reliability estimation data is low. Ratio of U grade estimation depends on some factors, like gross-count gamma ray logging system; uranium disequilibrium, sampels size; and other radioactive elements. In order to increase the validity and reliability estimation data, XRF analysis samples should be added by considering the borhole diameter and depth interval.

Published: June 2020

316L stainless steel is widely used as an orthopedic implant due to its high corrosion resistance and biocompatibility, but the weakness of these materials is low hardness and high wear. The surface must be modified to improve the material. For the purpose, a titanium nitride (TiN) thin film was deposited on the surface of SS 316L using DC sputtering technique. The sputtering process was carried out for various of a gas mixture of argon (Ar) and nitrogen (N2) such as 90 Ar: 10N2, 80 Ar: 20 N2, 70 Ar: N2, and 60 Ar: 40 N2, while the other parameters kept constant. The objective of the gas mixture variation is to find out the optimum condition of ratio Ar: N2 gas mixture with the highest hardness and lowest wear resistance. From experiment done it’s found that the highest hardness in order of 232.02 VHN, while before being coated the hardness is 133.61 VHN, or there is an increasing hardness by factor 1.73, while the wear resistance reduces from 11.6 × 10-8 mm2/kg to 1.17 × 10-8 mm2/kg or there is reducing in wear resistance by factor 9.9. The optimum conditions were achieved at Ar: N2 ratio = 70:30. From XRD analysis, it can be concluded that the crystal structure of TiN thin film is cubic with the peaks (111), (200), (202), (311) and (222). From cross-section microstructure analysis using Scanning Microscope Electron (SEM), it’s found the thickness of the thin film is 744 nm.
The influence of the locomotor stump’s form on the ocular prosthetics result with different methods of eye removal

Published: June 2020

Aim. To determine the optimal shape of the locomotor stump and the configuration of the corresponding ocular prosthesis, ensuring their maximum motility in patients with anophthalmia with different methods of eye removal.
Materials and methods. The study group consisted of 132 patients aged 1880 years after enucleation or evisceration. Examination methods included medical history; examination of eyelids, measurement of length and width of the palpebral fissure, as well as of the depth of conjunctival fornices on both sides; assessment of the volume, shape, surface topography, position and excursions of the locomotor stump, of the protrusion of the ocular prosthesis compared to the contralateral eye; photo registration of the studied parameters.
Results. During the study, there were 3 types of locomotor stump identified: moderate with retraction in the upper third; voluminous flattened; voluminous hemispherical. The locomotor stump after enucleation was voluminous flattened or moderate with retraction in the upper third. The best motility of the locomotor stump was noted nasally and downward. The motility of the ocular prosthesis was 47.4% compared to the contralateral eye. The locomotor stump after evisceration with keratectomy was voluminous hemispherical or voluminous flattened. Its motility in all four directions was about the same. The motility of the ocular prosthesis in comparison to the contralateral eye was 55.9%. The locomotor stump after evisceration without keratectomy was voluminous hemispherical, uniform, smooth. The motility of the locomotor stump was maximal in comparison to other groups and relatively equal in all four directions. The motility of the ocular prosthesis in comparison to the contralateral eye was 68.2%.
Conclusion. The optimal shape of the locomotor stump, providing the greatest motility of the ocular prosthesis is voluminous hemispherical. The same protrusion of the eyeball and that of the cosmetic prosthesis relatively to the frontal plane after enucleation is achieved by increasing the thickness of the prosthesis itself, which reduces its motility. Evisceration with implantation of the orbital prosthesis involves the use of a thin-walled ocular prosthesis, the back surface of which ideally repeats the locomotor stump surface and does not prevent its maximum motility. When removing a squinting eyeball with preserved corneal diameter, a smaller implant should be used to prevent excessive opening of the palpebral fissure, or to prefer evisceration with keratectomy.

During mumps outbreak in Perm, the clinical picture was characterized by a unilateral inflammation of the parotid salivary glands followed by bilateral damage and involvement of other glandular organs (pancreas, ovaries). The cause of mumps ictus in the studied territory was the infection, brought to an organized team of the hockey club MP against the background of reduced with age concentration of the level of protective antibodies to mumps.
Type 2 Diabetes in China – Considering Both Insurance Products and Individual Health Factors
Authors: Ying Celia Zhang 
Published: June 2020

For the past 30 years, the increase in the prevalence of type 2 diabetes mellitus (T2DM) in China has reached epidemic proportions. As a result, risk assessment guidelines need to be updated by taking into consideration of improvements in medical treatment and lifestyle intervention. This especially applies to living insurance benefit policies (such as critical illness and total permanent disability) and to medical products (hospitalization reimbursement and certain DM-related treatment benefits).
This will require taking into account the current epidemic figures of T2DM in China in pricing, targeting the correct insured group for the DM products and getting the correct risk profile by applying a dynamic underwriting protocol (such as using the rewards for medical intervention, and for primary prevention efforts to screen individuals who are at high-risk of diabetes).
This article analyzes both studies and surveys that been conducted in China showing the progress of this epidemic.
Magnitude-Dependent Transient Increase of Seismogenic Depth

Published: June 2020

AbstractThe thickness of the seismogenic zone in the Earth’s crust plays an important role in seismotectonics, affecting fault-system architecture and relative fault activity, earthquake size and distribution within a fault system, as well as long-term accumulation of tectonic deformation. Within the last two decades, several studies have revealed that aftershocks of large continental earthquakes may occur below the background depth of the seismogenic zone, that is, below the seismic–aseismic transition zone. This observation may be explained with a strain- and strain-rate-induced shift in rheological behavior that follows large mainshocks, transiently changing the deformation style below the seismogenic zone from incipient ductile to seismically brittle failure. As large earthquakes transiently deepen the seismic–aseismic transition zone, it is plausible to assume that larger mainshocks may cause stronger deepening than smaller mainshocks. Corresponding observations, however, have not yet been reported. Here, we use well-located seismic catalogs from Alaska, California, Japan, and Turkey to analyze if mainshock size positively correlates with the amount of transient deepening of the seismic–aseismic transition zone. We compare the depths of background seismicity with aftershock depths of 16 continental strike-slip earthquakes (6≤M≤7.8) and find that large mainshocks do cause stronger transient deepening than moderate-size mainshocks. We further suggest that this deepening effect also applies to the mainshocks themselves, with larger mainshock coseismic ruptures being capable of extending deeper into the normally aseismic zone. This understanding may help address fundamental questions of earthquake-source physics such as the assumed scale invariance of earthquake stress drop and whether fault-slip scales with rupture length or rupture width.

AbstractWe estimated the origin time of the 1854 Ansei–Tokai tsunami from the tsunami waveforms recorded at three tide gauge stations (Astoria, San Francisco, and San Diego) on the west coast of North America. The tsunami signal is apparent in the San Francisco and San Diego records, and the arrival time was 0–1 p.m. Greenwich Mean Time (GMT) on 23 December 1854, whereas the tsunami signal of Astoria is ambiguous, and the arrival time could not be determined from the waveform. The simulated waveforms on the basis of nonlinear dispersive wave theory by assuming an origin time of 0 a.m. GMT on 23 December arrived earlier than the observations. Cross-correlation functions between the observed and simulated waveforms recorded at San Francisco and San Diego showed a time gap between them of approximately 30 min. Based on these results, we concluded that the origin time of the 1854 Ansei–Tokai tsunami was approximately 00:30 a.m. GMT or 09:46 local time on 23 December. Our result is roughly consistent with reports by a Russian frigate anchored in Shimoda Bay, ranging the earthquake between 09:00 and 09:45 and the tsunami between 09:30 and 10:00. The earthquake was also reported in historical Japanese documents ranging from 8 and 10 o’clock in local time.

Published: June 2020

Background: Chronic renal failure (CRF) presents with an array of cutaneous manifestations. Newer changes are being described since the advent of hemodialysis, which prolongs the life expectancy, giving time for these changes to manifest. Aim: The aim of this study was to evaluate the prevalence of dermatologic problems among patients with chronic renal failure (CRF) undergoing hemodialysis. Methods: ninty three .. patients with CRF on hemodialysis were examined for cutaneous changes. Results: all the patients complained of some skin problem. The most prevalent finding was xerosis (54.8%), followed by pallor (21.5%), pruritus (19.35%) and cutaneous pigmentation (18.3%). Other cutaneous manifestations included Kyrle's disease (5.4%); fungal (5.4%), bacterial (6.5%) and viral (3.2%) infections; purpura (9.7%). The nail changes included half and half nail (21%), koilonychia (39.78%), onychomycosis (1.08%), onychorrhexis (6.45%), splinter hemorrhages (1.08%), and Beau's lines (2%). Hair changes included sparse hair (18.28%), and brittle and lusterless hair (11.83%). Oral changes included macroglossia with teeth markings (23.65%), . Some rare manifestations of CRF like uremic frost, gynecomastia and pseudo-Kaposi's sarcoma were not observed. Conclusions: CRF is associated with a complex array of cutaneous manifestations caused either by the disease or by treatment. The commonest are xerosis and pruritus and the early recognition of cutaneous signs can relieve suffering and decrease morbidity.

Published: June 2020

Background: A number of protective and cautionary protocols have been adopted to control the rapid spread of COVID-19 in Sudan. People’s commitment to these protocols is affected by their knowledge, attitudes, and practices (KAP).
Objective: To measure the Sudanese population’s KAP in relation to COVID-19 during the pandemic.
Method: A web sample was enrolled with success via the authors’ relations with citizens and standard media in Khartoum, Sudan. A self-administered online KAP questionnaire was completed by the respondents.
Results: Among the study sample (n=2336),66.4% between 18 and 29 years old, 60.7% were ladies, 75.9% had a high school education, and 76.1% were Khartoum citizens. The general correct rate of the knowledge questionnaire was 84.7%. The majority of the participants (94.8%) were ready to commit to the decision of staying at home. A large proportion of the participants (92%) frequently washed their hands or using antiseptic.
Conclusion: Health teaching programs geared to enhancing COVID-19 knowledge are useful for Sudan citizens fostering positive attitudes and disseminating knowledge relating to helpful practices. Due to the limited sample representativeness, we must be cautious when generalizing these findings.

Aborto séptico en el ICSS.
Authors: Velasco L. Germán 
Published: June 2020

Un grupo de 29 pacientes de los servicios obstétricos del ICSS con abortos sépticos complicados, todos provocados, se manejan de acuerdo a criterios definidos. Diez casos con patología anexial, doce de peritonitis y siete septicemias cuya permanencia promedio fue de 13, 20 y 36 respectivamente, con un total de 575 días cuyo costo se estima en dos millones de pesos. Sóol hubo una defunción. Se sugieren modificaciones a la clasificación del I.M.I. Se recomienda la intervención quirúrgica del foco séptico primario, recalcando la utilidad de la colpotomía; cada paciente requirió dos cirugías. Se verifica la bondad de la penicilina y se insiste en la combinación de antibióticos que se rotan cada 4 a 5 días, si es necesario. Las maniobras abortivas haitualmente practicadas por auxiliares de enfermería y comadronas, en casa de las pacientes, con un costo muy bajo utilizando sonda, a veces con alambre, dieron cuatro perforaciones uterinas y dos de sigmoide; el motivo conciente fue el económico, la soltería, la planificación familiar y el temor a perder el empleo. Se encontraron abortos clandestinos, temor a perder el empleo y salarios por debajo del mínimo legal.

En 27 mujeres normales, solicitaron la inserción de un dispositivo intrauterino anticonceptivo (DIU) a la Consulta Externa del HUV, se obtuvo aceptación voluntaria para estudiar las actividades uterina y antidiurética e inducir una diuresis acuosa durante la menstruación y en las 2 a 3 horas previas a la inserción del DIU. La diuresis acuosa, abtenida adm nistrando sobrecargas de agua por vía oral e intravenosa (20 ml/Kg. de peso corporal), produjo una inhibición simultánea de la alta contractilidad del útero menstrual y de la actividad antidiuréca. Este efecto se comunica por primera vez a la literatura médica.Estos resultados, así como los de otros estudios preliminares que discutimos en éste artículo, refuerzan claramente la hipótesis que plantea la participación de la vasopresina u hormona antid urética (ADH), en la regulación de la elevada contractilidad uterina característica de la menstruación.
