Open Journal of Endocrine and Metabolic Diseases (OJEMD) , 2017, DOI: 10.4236/ojemd.2017.78015
Abstract: Background: Diabetes Mellitus results in several serious complications and among them foot problem is one of the commonly ignored complications. This study is an attempt to find out the level of patient’s awareness and practice in Nepalese context. Objective: The aim of this study is to determine the knowledge and practice of foot care among patients with diabetes in Nepal. Methods: This is a six-month long cross-sectional study done in the General Practice Clinic of Tribhuvan University Teaching Hospital. Diabetic patients were given structure questionnaires on knowledge, foot care practices, and demographic information. Results: Illiteracy was found be significantly associated with poor knowledge and practice of foot care. Those who have no education are more likely to have poor knowledge and foot care practice. The odds of having poor knowledge is 6.414 (3.075, 13.379) in those who have no education/primary education compared to those who have education and the odds of poor foot care practice is 4.5180 (2.077, 8.411) in those who have no education/primary education compared to those who have education with significance of <0.001. Conclusion: This study has highlighted the need of appropriate education intervention for the patients with diabetes who have no education background to prevent from foot complications. Health education materials such as graphics, photos are needed to make them comprehensible for the illiterate patients.
Emergency department triage: an ethical analysis
Ramesh P Aacharya, Chris Gastmans, Yvonne Denier
BMC Emergency Medicine , 2011, DOI: 10.1186/1471-227x-11-16
Abstract: In emergency department triage, medical care might lead to adverse consequences like delay in providing care, compromise in privacy and confidentiality, poor physician-patient communication, failing to provide the necessary care altogether, or even having to decide whose life to save when not everyone can be saved. These consequences challenge the ethical quality of emergency care. This article provides an ethical analysis of "routine" emergency department triage. The four principles of biomedical ethics - viz. respect for autonomy, beneficence, nonmaleficence and justice provide the starting point and help us to identify the ethical challenges of emergency department triage. However, they do not offer a comprehensive ethical view. To address the ethical issues of emergency department triage from a more comprehensive ethical view, the care ethics perspective offers additional insights.We integrate the results from the analysis using four principles of biomedical ethics into care ethics perspective on triage and propose an integrated clinically and ethically based framework of emergency department triage planning, as seen from a comprehensive ethics perspective that incorporates both the principles-based and care-oriented approach.Emergency care is one of the most sensitive areas of health care. This sensitivity is commonly based on a combination of factors such as urgency and crowding [1]. Urgency of care results from a combination of physical and psychological distress, which appears in all emergency situations in which a sudden, unexpected, agonizing and at times life threatening condition leads a patient to the emergency department (ED).The Australasian College for Emergency Medicine (ACEM) defines ED overcrowding as the situation where ED function is impeded primarily because the number of patients waiting to be seen, undergoing assessment and treatment, or waiting to leave exceeds the physical and/or staffing capacity of the ED [2]. ED overcrowding is a common
Certain Algebraic Test for Analyzing Aperiodic Stability of Two-Dimensional Linear Discrete Systems  [PDF]
P. Ramesh
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.76061
Abstract: This paper addresses the new algebraic test to check the aperiodic stability of two dimensional linear time invariant discrete systems. Initially, the two dimensional characteristics equations are converted into equivalent one-dimensional equation. Further Fuller’s idea is applied on the equivalent one-dimensional characteristics equation. Then using the co-efficient of the characteristics equation, the routh table is formed to ascertain the aperiodic stability of the given two-dimensional linear discrete system. The illustrations were presented to show the applicability of the proposed technique.
Stability Analysis of Multi-Dimensional Linear Time Invariant Discrete Systems within the Unity Shifted Unit Circle  [PDF]
P. Ramesh
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.76060
Abstract: This technical brief proposes a new approach to multi-dimensional linear time invariant discrete systems within the unity shifted unit circle which is denoted in the form of characteristic equation.The characteristic equation of multi–dimensional linear system is modified into an equivalentone- dimensional characteristic equation. Further formation of stability in the left of the z-plane, the roots of the characteristic equationf(z) =0 should lie within the shifted unit circle. Using the coefficients of the unity shifted one dimensional equivalent characteristic equation by applying minimal shifting of coefficients either left or right and elimination of coefficient method to two triangular matrixes are formed. A single square matrix is formed by adding the two triangular matrices. This matrix is used for testing the sufficient condition by proposed Jury’s inner determinant concept. Further one more indispensable condition is suggested to show the applicability of the proposed scheme. The proposed method of construction of square matrix consumes less arithmetic operation like shifting and eliminating of coefficients when compare to the construction of square matrix by Jury’s and Hurwitz matrix method.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2015, DOI: 10.4236/jmmce.2015.35044
Abstract: Natural fibres will take a major role in the emerging “green” economy based on energy efficiency, the use of renewable materials in polymer products, industrial processes that reduce carbon emissions and recyclable materials that minimize waste. Natural fibres are a kind of renewable resources, which have been renewed by nature and human ingenuity for thousands of years. They are also carbon neutral; they absorb the equal amount of carbon dioxide they produce. These fibers are completely renewable, environmental friendly, high specific strength, non-abrasive, low cost, and bio-degradability. Due to these characteristics, natural fibers have recently become attractive to researchers and scientists as an alternative method for fibers reinforced composites. This review paper summarized the history of natural fibers and its applications. Also, this paper focused on different properties of natural fibers (such as hemp, jute, bamboo and sisal) and its applications which were used to substitute glass fiber.

Abstract: Most Eritrean farmers do not adopt soil conservation measures and till even sloppy fields 2 - 4 times for planting sorghum (Sorghum bicolor L.) with a view to facilitate rainwater intake. Field experiments were conducted at Hamelmalo to optimize tillage and irrigation requirements of sorghum in loamy sand. Tillage treatments were conventional tillage (4 times) on existing slopes (CTf), conventional tillage on managed plots (terraced) with residue (CTm + R) and without residue (CTm - R), reduced tillage (single tillage 4 days after heavy rainfall) on managed plots with residue (RTm + R) and without residue (RTm - R) and no tillage (direct planting) on managed plots with residue (NTm + R) and without residue (NTm - R) randomized in four replications. Tillage in CTm and CTf was same. Experiment was repeated in year II along with a new experiment in split plot design with same tillage treatments in main plots and 4 irrigation treatments in subplots in 3 replications. Irrigation treatments were rainfed (I0), 70 mm irrigation at 50% depletion of soil moisture in CTm - R from 1 m profile after end of monsoon (I1), 70 mm irrigation 7 days after irrigation in I1 (I2), and 70 mm irrigation 7 days after irrigation in I2 (I3). Bulk density increased and infiltration rates decreased by harvesting due to tillage but changes were lower in residue plots of NT and RT than CT. Optimum soil moisture for emergence of sorghum was within 0.145 ± 0.002 m3 m-3 at which soil strength was well below critical level for root growth. Soil strength in tilled layer due to intermittent wetting and drying following planting exceeded 2000 k

Abstract: Kidney stone consists of various compounds. Mineral oxalate monohydrate and di-hydrate are the main constituent of kidney stones. However, the formation of calcium oxalate kidney stones is still not clearly understood. In this field of studies, several new hypotheses are created, which includes nucleation, reduction of nucleation, crystal growth and or aggregation of formation of different crystals such as oxalate monohydrate and oxalate di-hydrate. The effect of some urinary species such as ammonium oxalate, calcium, citrate, proteins and trace elements were reported by the author. The kidney stone constituents along with trace minerals are grown in silica gel medium (SMS) which provides the necessary growth simulation (in-vivo). In the artificial urinary stone growth process, growth parameters within the different chemical environments were carried out and reported for several urinary crystals such as CaHP, SrHP, SrMHP, BaHP, BaMHP and MgHP. In the present investigation, BaSrCrMHP (Barium Strontium Chromium Magnesium Hydrogen Phosphate) crystals are grown in different growth faces to attain the total nucleation reduction. Extension of this investigation, many characterization studies have been carried out and compared with reported results.

International Journal of Engineering Innovations and Research , 2013,
Abstract: Cloud computing investigate the problem of data security in cloud data storage, which is essentially a distributed storage system. Distributed storage integrity auditing mechanism, utilizes the homomorphic token and distributed erasure-coded data. The proposed design allows users to audit the cloud storage with very lightweight communication and computation cost. The auditing result not only ensures strong cloud storage correctness guarantee, but also simultaneously achieves fast data error localization, i.e., the identi cation of misbehaving server and recover the corrupted data. Considering the cloud data are dynamic in nature, the proposed design further supports secure and efficient dynamic operations on outsourced data, including block modi cation, deletion, and append. Analysis shows the pro-posed scheme is highly efficient and resilient against Byzan-tine failure, malicious data modi cation attack, and even server colluding attacks. With the advent of data storage and new technology trends that result in new failure modes for storage, interesting challenges arise in ensuring data integrity and security. In this paper, we discuss the cause of integrity violations and implementation issues to perform efficient integrity assurance. The main aim of this paper is to prevent the file from integrity violations and recovering the corrupted file with low cost overhead.
