Effect of Silver Oxide Film Thickness on Some Optical Parameter

Films of silver oxide of different thickness have been prepared by the chemical spray paralysis. Transmission and absorption spectra have recorded in order to study the effect of increasing thickness on some optical parameter such as reflectance, refractive index , and dielectric constant in its two parts . This study reveals that all these paramters affect by increasing the thickness

Boundary value problems for hybrid differential equations

This note is motived from some papers treating  the hybrid differential equations. An existence theorem for this equation is proved. Some fundamental differential inequalities for hybrid differential equatins  are also established which are utilized to prove the existence of extremal solutions. Necessary tools are considered and the comparison principle is proved which will be useful for further study of qualitative behavior of solutions

The objective of this study was to analyze the principal's academic supervision and teacher's work motivation toward the performance state elementary school teachers in Undaan District, Kudus Regency. This research is correlational research with a quantitative approach. The independent variables determined were the principal's academic supervision and teacher's work motivation, while the dependent variable observed was teacher performance. The study was conducted in 33 state elementary schools in Undaan district, Kudus Regency with a sample of 181 respondents. Data collection techniques in this study used interviews, questionnaires, and documentation. Data analysis was performed statistically using descriptive statistical analysis, prerequisite analysis, and final analysis for hypothesis testing. The results of the study found that (1) the principal's academic supervision has a significant effect of 10.10% toward the performance state elementary school teachers in Undaan District, Kudus Regency; (2) the teacher's work motivation has a significant effect of 37.40% toward the performance state elementary school teachers in Undaan District, Kudus Regency; and (3) the principal's academic supervision and teacher's work motivation has a significant effect of 38.40% toward the performance state elementary school teachers in Undaan District, Kudus Regency

Analisis Strategi Pengembangan Bisnis Jasa Konstruksi (Studi Kasus: PT Tri Manunggal Karya)

Increasing competition of construction business in Indonesia forces PT Tri Manunggal Karya (PT TMK) to innovate to survive in the construction industry. One way is by having a competitive strategy for its business development. As a holding company, a proper strategy is highly required by PT TMK to open up market opportunities for the company and its subsidiaries and to avoid the risk of business failure and financial losses. This study aims to analyze internal and external factors and analyze the priority strategies for PT TMK development. The analytical methods used were Internal Factor Evaluation (IFE) Analysis, External Factor Evaluation (IFE) Analysis, Strength, Weakness, Opportunity, and Threats (SWOT) Analysis, Analytical Hierarchy Process (AHP) Analysis. The result shows that the external condition of PT TMK is in a high position in responding to opportunities and threats. Its internal figures are in a strong stand in utilizing strengths and overcoming its weaknesses. Opportunity in the company's industry can be concluded because infrastructure development and competent human resources are still limited in the Eastern parts of Indonesia. The threats are post-pandemic conditions and fast-growing construction technology. The result of the Analytical Hierarchy Process (AHP) shows the strategy of acquiring new business units is considered as the main priorities, followed by expansion out of Java Island

Does the Adoption of EMR Systems Inflate Medicare Reimbursements?

The adoption of EMR systems has been argued to lead to physicians “upcoding” their patients to inflate insurance reimbursements. In this paper, we examine if the adoption of the Clinical Physician Order Entry (CPOE) system is associated with an increase in the complexity of the patients\u27 case mix that hospitals report (termed upcoding ). We make use of a staggered roll-out of the Recovery Audit Program to combat upcoding as a natural experiment to assess the impact of the adoption of the CPOE systems on the case mix that a hospital reports. We find that on average the adoption of CPOE systems is associated with an increase in the reported case mix of hospitals, and that the Audit program has had an effect on reducing the case mix that hospitals report to Medicare for reimbursement. Implications for preventing inflated reimbursements due to upcoding are discussed

Gamma-D crystallin gene (CRYGD) mutation causes autosomal dominant congenital cerulean cataracts

Congenital cataracts are a major cause of bilateral visual impairment in childhood. We mapped the gene responsible for autosomal congenital cerulean cataracts to chromosome 2q33-35 in a four generation family of Moroccan descent. The maximum lod score (7.19 at recombination fraction theta=0) was obtained for marker D2S2208 near the g-crystallin gene (CRYG) cluster. Sequencing of the coding regions of the CRYGA, B, C, and D genes showed the presence of a heterozygous C>A transversion in exon 2 of CRYGD that is associated with cataracts in this family. This mutation resulted in a proline to threonine substitution at amino acid 23 of the protein in the first of the four Greek key motifs that characterise this protein. We show that although the x ray crystallography modelling does not indicate any change of the backbone conformation, the mutation affects a region of the Greek key motif that is important for determining the topology of this protein fold. Our data suggest strongly that the proline to threonine substitution may alter the protein folding or decrease the thermodynamic stability or solubility of the protein. Furthermore, this is the first report of a mutation in this gene resulting in autosomal dominant congenital cerulean cataracts

Is there an association between vitamin D and risk of stroke?: a North Indian study

Background: Vitamin D deficiency is present in India in epidemic proportions despite plenty of sunshine. Reduced plasma 25(OH) D concentrations as a diagnostic marker of vitamin D deficiency have been in past decade associated with several well-established risk factors for ischaemic stroke, such as arterial hypertension, thrombosis, atherosclerosis. The aims and objectives of this study was to compare the serum 25(OH) D levels between the first ever acute stroke patients and healthy controls.Methods: A cross-sectional, case control study was conducted in a tertiary care hospital in New Delhi situated in north India. Serum 25‑hydroxyvitamin D (25(OH) D) levels in 85 patients of ischemic stroke, presenting within 7 days of onset of stroke was measured and was compared with 70 age and gender matched controls.Results: The mean age was 61.02±11.58 years and 58.63±11.28 years in cases and controls respectively. Females constituted 37.6% of the total number of cases and 43.4% of the controls. The age and gender-distribution were comparable between the cases and controls. The median value (IQR) of serum 25(OH) vitamin D level was 7.94 ng/mL (4.59-14.00) in the cases and it was 8.82 ng/mL (5.59-14.70) in the controls. The difference between the serum 25(OH) vitamin D levels of the two groups was not found to be statistically significant.Conclusions: There is a high prevalence of biochemical hypo-vitaminosis D in apparently healthy Indians of all age and sex groups despite adequate sunshine. There is no association between low vitamin D levels and stroke
