Comparing SSD Forensics with HDD Forensics

The technological industry is growing at an unprecedented rate; to adequately evaluate this shift in the fast-paced industry, one would first need to deliberate on the differences between the Hard Disk Drive (HDD) and Solid-State Drive (SSD). HDD is a hard disk drive that was conventionally used to store data, whereas SSD is a more modern and compact substitute; SSDs comprises of flash memory technology, which is the modern-day method of storing data. Though the inception of data storage began with HDD, they proved to be less accessible and stored less data as compared to the present-day SSDs, which can easily store up to 1 Terabyte in a minuscule chip-size frame. Hence, SSDs are more convenient and user-friendly, where, in contrast, HDDs often require some degree of technical knowledge. However, since SSDs are still a relatively new phenomenon, it has proved to create myriads of problems in the digital forensics department. Since, SSDs are still a more modern concept, the tools that digital forensics employ to investigate evidence obtained from HDDs are not proving to be as efficient; this is primarily due to the fact that data in flash memory drives can only be written if the data unit or data block is erased, ergo, an erase operation occurs every time before something is written into the flash memory. Therefore, the aim of this research is to critically analyze the results obtained by running forensic tools on an HDD and SSD; the results would pertain to the image generated from the HDD and SSD

ECHO OF LODHRADI KASHAYA IN LIPID PROFILE OF TYPE 2 DIABETES MELLITUS PATIENTS

Objective: Lipid profile is matter to concern in fast changing lifestyle, and especially in diabetic mellitus (DM) patients. In arena of DM, obesity and high lipid contour is a causative problem and lead to generate the related problems too. Hence, tracking of lipid profile in DM patients is necessary as part of treatment approach. Hence, the present study was conducted to track the effect of Lodhradi Kashaya spray dried (LKSD) powder on lipid profile in Type 2 DM patients.Methods: Total 31 patients were taken following the guideline mention in Central Council for Research in Ayurveda and Siddha protocol for DM research. They were divided into two groups, Groups A and B and given LKSD (4 and 2 g TDS (three times a day), respectively, dissolved in water) for 3 months. They are investigated for their blood serum creatinine and lipid profile (cholesterol, low-density lipoprotein [LDL], high-density lipoprotein [HDL], very LDL [VLDL], and triglyceride). The patients response has also been noted regarding palatability acceptance and ease of administration.  Result: LKSD was found significantly effective in total cholesterol (p=0.001 and 0.073), triglyceride (p=0.002 and 0.003), HDL (pË‚0.001 and 0.026), LDL (p=0.563 and pË‚0.001), and VLDL (p=0.024 and 0.003). Patients had reported that formulation is easy to take in spite of its astringency in taste.Conclusion: Lodhradi Kashaya has capability to control and take care of disturbance in lipid profile in DM patients and thus enhance their living confidence.Â

Voltage profile improvement of weak grid with solar PV integration

The objective of this paper is to improve the voltage profile of the grid in pertinence to grid due to power injection from distributed solar photovoltaic (PV) arrays. Weak grids are modeled as worldwide adaptation of net metering, transactive energy systems, and the possibility of further deterioration of power quality with higher grid penetration. In this paper, a solar PV integrated weak distribution grid modelled as the PV arrays being frequently connected in rural areas, due to various reasons like cheap real estate and lack of accessibility. In this paper, three case studies of PV generation are simulated, i.e., scheduled solar PV generation less than load requirement, PV generation equal to load requirement, and PV generation more than load requirement, by considering the daily solar irradiation and load demand profiles of a residential area under study

The study of risk factors and prognostic indicators in patients with bacteremia due to ESBL producing organisms

Background: There is a growing incidence of extended-spectrum beta-lactamases (ESBL) infections worldwide. ESBL bacteremias have been associated with poor outcomes, higher costs and increased durations of hospital stay. The objective of the study was to identify the risk factors in these patients along with antibiotic susceptibility patterns to help identify the patients with poorer prognosis and in guiding treatment decisions more effectively.Methods: An observational case-control study conducted in a tertiary care hospital in south India over a duration of 18 months. Cases were defined as an adult in-patient who had infection with blood cultures showing growth of ESBL-producing bacteria. A total of 70 patients were included in the study group and subjected to evaluation to determine the risk factors, prognostic indicators and the antibiotic susceptibility.Results: The major risk factors for ESBL-bacteremia identified were prior admission, prior antibiotic usage, prior Foleys catheter and the presence of a vascular catheter. Pneumonia as the source of bacteremia and requirement of mechanical ventilation were identified as indicators of poor prognosis. Carbapenems, cefoperazone-sulbactam and piperacillin-tazobactam showed excellent sensitivity against ESBL-bacteremia.Conclusions: The findings of this study emphasizes the importance of recognizing ESBL-bacteremias in patients with risk factors, so that patients who are at risk to have a worse prognosis can be promptly started on a susceptible antibiotic

A clinical study of surgical management of distal femur fracture using locking compression plate

Background: Fractures of distal femur are common due to increased road traffic accidents and fall from height because of increased construction activities. These fractures are quite disabling hence, these fractures necessitate early stabilization of fractures. Internal fixation with LCP has shown to give one of the best results in terms of recovery, fracture union, and clinical outcome. The aim of the study the clinical outcome of treatment of distal femur fractures using locking compression plates.Methods: A total of n=20 cases of distal femur fractures treated with LCP from December 2013 to June 2015 at NMCH and RC, Raichur. They were admitted and examined according to protocol clinically and radiologically. All patients were followed up for a minimum of 6 months and outcome assessed with Neer’s score.Results: All fractures healed with an average duration of 16 weeks which is comparable with other studies. We had two cases of varus collapse one was due to early weight bearing in one case and other case is due to gross communition. One case had an implant failure (plate breakage) due to early weight bearing. Cases needing hardware revision is comparable to other studies at 10%. Average Neer's knee score was 76.Conclusions: we have found higher Neer’s scores in this study. The LCP also prevents compression of periosteal vessels. It may not completely solve the age-old problems associated with any fracture like non-union and malunion, but is a valuable technique in the management of these fractures. But however, in type C fractures the outcome is poorer

A study of proximal humerus fractures treated by PHILOS plating in a tertiary care hospital

Background: Proximal humeral fractures are commonly presented in the orthopedic practice. The usual method of treatment was conservative in the past. However, the results and functional outcomes were not good. With the development of PHILOS locking plates, the functional outcomes are known to be improved. We in the present study tried to evaluate the functional outcomes of proximal humerus fractures treated with PHILOS plates.Methods: This prospective study was conducted in all Adult patients with closed two-part and three-part fractures of the proximal humerus, those who have reported within a week of the injury were included in the study. A total of n=30 patients were included in the study based on the inclusion and exclusion criteria. A standard surgical approach with PHILOS plate was used and patients were followed up for 19 to 24 months.Results: n=30 patients out of which n=16 (53.33%) were males and n=14 (46.67%) were females. The most common age group involved in the fractures was 31-35 years n=9 (30%) of the patients. Most of the patients n=21 (70%) were having Neer's two-part fractures and three-part fractures were found in n=6 (20%) and four part in n=3 (10%). The overall results in the study were 66.67% of patients had excellent results and 16.67% had good results and 10% had poor results.Conclusions: PHILOS locking plates is a better treatment option for fractures of proximal humerus especially in cases of poor bone quality and comminuted fractures

Comparative analysis of biliary cholesterol levels in iron deficient and non-iron deficient patients operated for gall stone disease

BACKGROUND AND OBJECTIVE: Gall Stone disease is a common clinical entity affecting adult population of both sexes. The old saying, that gall stone sufferer is a fat, fertile, female of fifty is only partly true, as the disease has been observed in women after their first delivery and also in underweight and thin people. Several etiological factors have been studied in the formation of gall stones. There has been recent interest in establishing the role of several nutritional trace elements in the pathogenesis of gall stone disease. Iron Deficiency is a new and particularly interesting parameter which has been studied lately, but with a few studies showing conflicting results. Establishing the role of Serum Iron in the etiology of Gall stones is of special importance in our population group because of the huge prevalence of nutritional deficiencies. It also provides scope for early detection, treatment and risk modification if its role as an etiologic/risk factor is clearly defined. AIM: The study is aimed at establishing the role of iron deficiency in the super saturation of bile with respect to cholesterol, which leads to gall stone formation. METHODS: A study was done between December 2014 to September 2015 at the department of General Surgery.50 patients suffering from Cholelithiasis, confirmed by USG, were divided into two groups based on serum iron values. Group A, consists of patients with normal serum iron (non-anaemic) and group B, of patients with less than normal serum iron (anaemic). Serum Iron, Biliary Cholesterol and Serum Cholesterol of all the patients was obtained. The Biliary cholesterol levels and Serum cholesterol levels of both the groups was analysed by using a student t-test. RESULTS: Out of the 50 Patients, 40 (80%) were female and 10 (20%) were males. The female to male ratio was 4:1. The Biliary Cholesterol values for Group A and B respectively were 754.5 ± 398.3 and 1184.7 ± 405.2 mg/dl. The Biliary Cholesterol levels were significantly higher in the Iron Deficient group (Group B) than compared to the Non-Iron Deficient Group. This result was extremely statistically significant with a p value of <0.0004. Similarly, an independent t-test comparing Serum Cholesterol levels in Non-Iron Deficient (184.8 ± 35 mg/dl) and Iron Deficient subjects (171 ± 49.3 mg/dl) did not find a statistically significant difference. (p=0.2544). CONCLUSION: These results suggest that Iron Deficiency has an association with Biliary Cholesterol Levels

Computational Fluid Dynamic Analysis of Vortex Generators on MAV.

ABSTRACT Micro Vortex generators are very small components deployed on the wings to control airflow over the upper surface of the wing to affect the boundary layer over it. These are employed onto a Micro aerial vehicle (MAV) of fixed wing type with an S5010 which is a low Reynolds number airfoil. This airfoil provides good aerodynamic results as compared to many low Reynolds number airfoils. Micro vortex generators are used to enhance the performance through controlling airflow at different speeds and angle of attack. The comparison of a half part of the MAV wing which is designed in CATIA, with and without the vortex generators on its leading edge at 10% of its chord length is done to show how the vortex generators improve the performance and control authority at different speeds and angle of attacks. These are shown with the velocity and pressure distribution around the wing by considering laminar flow in the simulation
