Monte carlo simulation of transient CSD in a continuous crystallizer
No full textA Monte Carlo simulation scheme is proposed for transient crystal size distribution in a continuous crystallizer. The suggested scheme can taken into account dispersion effects of growth rate, shape factor and birth size on crystal size distribution. This method is simple and more versatile than solution of the number balance equation or the finite‐state Markov chain model. The proposed algorithm of the process has a very simple structure and can be easily implemented on a personal computer. The present contribution is extension of an earlier work of Sen Gupta and Dutta.</p
Body fat composition as a marker for risk assessment in hypertension
No full textIntroduction: High blood pressure (BP) is one of the most common chronic medical problems prompting visits to primary health-care providers. The incidence of lifestyle diseases over the years has shown an upward trend in developing countries too, which is a cause of grave concern for the health care professionals. Research suggests that undesirable body composition has a major bearing on health, fitness and lifestyle diseases such as hypertension, ischemic heart disease, and diabetes. Study: The aim of the study was to compare the body composition of hypertensive patients with normal subjects using state of the art impedance based noninvasive body composition analyzer. The study evaluated the body composition of hypertensive patients and compared the same with subjects with normal BP. The study was carried out at a tertiary care hospital in Pune. Body composition variables considered for the study were anthropometry, percent body fat, lean body mass, fat distribution, and visceral fat composition. Results: The analysis of body fat included obesity degree, visceral fat area (VFA), body fat mass, and percent body fat. The mean body fat mass was found to be 21.7Kg. The mean percent Body Fat was 28.9%, which was much higher than the normal. Various parameters depicting body fat were compared. All of them, namely body fat mass, percent body fat, obesity degree, and VFA were found to be significantly higher in hypertensives as compared to the other group. Conclusion: Besides other anthropometric parameters, assessment of VFA may be included as an essential measure to assess and even predict hypertension. Those with high VFA must be monitored closely for developing hypertension and other lifestyle diseases
Prevalence of visual impairment and severity of diabetic retinopathy in various ethnic groups in the UK
No full textDiabetic Retinopathy (DR) is a leading cause of visual impairment (VI) in the working population. Minor ethnic groups are at increased risk of diabetes. Diabetic Retinopathy In Various Ethnic groups in the United Kingdom (DRIVE UK) is a cross-sectional study to estimate the prevalence of DR, VI and associated risk factors for sight threatening diabetic retinopathy (STDR) in Afro-Caribbeans (AC) and South Asians (SA) compared to Caucasians. People with diabetes in two regions in the United Kingdom who were screened and/or treated for DR from September 2008 to September 2009 were included in this study. VI and severe visual impairment (SVI) were defined as Snellen visual acuity of ≤ 6/18 and ≤ 6/60 respectively. DR was graded according to National Screening Committee (NSC) for diabetes guidelines UK.
There were 57,144 people on the diabetic register, of which retinopathy data was available from 50,285 (88.1%) subjects (type 1 n=3,323, type 2 n=46,962). In type 1 and type 2 diabetes, any DR was detected in 53.1%, 39.5%, diabetic maculopathy in 13.1%, 8.4% and STDR in 9.91%, 4.0% of people respectively. STDR was significantly more prevalent in the SA (10.3%) and AC (11.5%) populations compared to Caucasians (5.5%). Overall VI was significantly higher in the ethnic minority population. A total of 7.5% (95% CI 7.3, 7.8) people with diabetes were not eligible for driving based on their visual acuity, 3.4% (95% CI 3.2, 3.5) were classified as VI and 0.4% (95% CI 0.33, 0.44) as SVI. Risk factors for STDR were found to include longer duration of diabetes and higher mean HbA1c.
This study provides information that could be used to help develop future service frameworks and guidelines for local health bodies responsible for delivery of end userservices. The study also supports the need to explore the role of inflammatory, genetic and epigenetic factors as markers for ethnic differences in DR and potential treatment avenues for diabetic retinopathy

Evolution of the pore pressure due to vibratory installation of sheet piles in sand
No full textVibratory installation of sheet piles is the most economic and suitable for the sandy soil because of its mechanism. However, the process induces excess pore pressure in saturated conditions leading to subsidence. This research focuses on the development of a tool-based solution to predict the excess pore pressure due to vibratory installation, which shall be verified by the postdiction of Kademuur Damrak measurements. This tool will help engineers quantify the impact of generated excess pore pressure on adjacent structures. The proposed work attempted to achieve its objective by answering the following main and sub research questions. How can the existing knowledge on generation and evolution of porewater pressure during vibratory installation be effectively integrated into a model/tool, which verified by the postdiction of Kademuur Damrak measurements, can practically estimate the porewater over-pressure during vibratory installations? • What are the parameters that influence the dissipation of the excess pore pressure? • How does the generation and dissipation of excess pore pressure vary in the liquefied zone from non-liquefied? • How can the vibration attenuation affect the generation of excess pore pressure in the sand? • What are the limitations and controlling parameters of this model or tool? The proposed work combines dynamic soil response and transient groundwater flow model to simulate the evolution of pore pressure due to vibratory loading. Based on the degree of modulus degradation due to the vibratory loading the soil, it is zoned into three. This is also termed as a multiscale computational framework. This allows for the formations liquefied and non-liquefied zone. The threshold acceleration of 0.1g - 0.3g must be available for the soil to liquefy [66]. The non- liquefied zone is fed by the groundwater flow from the liquefied zone. According to the Theis equation, head response due to constant pumping in an aquifer is influenced by the rate of discharge (V), storativity(S) and transmissivity(T), distance from the source. This inspired to model the driving of sheet pile with an analogous to the pumping of well. During the constant head loading due to the pumping, there is an increase in the head radially outward from the source. This resembles the phenomenon of pre-shearing in the field. The driving of the sheet pile was stimulated by the constant head loading. The application of time series analysis (PRIFICT method) [8] provides the first estimation of the pore pressure response from the first of three days of field piezometric data of Kademmur damrak. The semi-empirical model was formulated influenced by the head response of the slug test. The response of the time series analysis helped to calibrate the semi-empirical model. The relationship evolved between the physical and modelling parameters established that the hydraulic conductivity is the key parameter in both the generation and the dissipation of the excess pore pressure. The analysis of the field data establishes the conservative assumption of 1m for the width of the liquefaction zone. The analysis of accelerometer data from the Amsterdam noord zuid metro line tunnel helps to establish the dependency of liquefaction on acceleration amplitude. This bolstered the threshold acceleration for liquefaction to be 0.1 - 0.3g. The simple flow only Plaxis model helped to validate the proposed hypothesis. The hydraulic conductivity was established as the key parameter of the model. The integration of dynamic generation and transient groundwater flow model helped to analyse the evolution of excess pore pressure
The role of early nephrostomy in the management of patients with hyperkalaemia and renal failure due to ureteric obstruction
No full textObjective: To assess the outcomes of early percutaneous nephrostomy in obstructed hydronephrosis and hyperkalaemia from ureteric obstruction.
Methods: Patients were diagnosed with hyperkalaemia with serum potassium >5.0 mmol/L and hyperkalaemia was graded as mild (5.0–6.0 mmol/L), moderate (6.1–7.0 mmol/L) or severe (>7.1 mmol/L). Data on age, sex, clinical presentation, presence of concurrent disease, creatinine, potassium, haemoglobin concentration, time interval in doing the nephrostomy since their first presentation, any prenephrostomy medical correction of hyperkalaemia and complications were collected.
Results: A total of 61 patients (40 males and 21 females) with mean age of 69.7 years (ranged 35 to 94 years) underwent 69 procedures. Prior to the nephrostomy, the serum potassium was mildly elevated in 42 cases, moderately elevated in 17 cases and severely elevated in 10 cases. The overall mean level of potassium before intervention was 6.1 mmol/L (range: 5.1 mmol/L-9.3 mmol/L). Forty (58%) had nephrostomy without prior medical treatment of the hyperkalaemia. The mean serum potassium in these patients was 5.6 mmol/L (range: 5.1 mmol/L-7.5 mmol/L). Twentynine (42%) had medical treatment of the hyperkalaemia prior to nephrostomy. The mean potassium level in these patients was reduced from 6.7 mmol/L (range 5.4 mmol/L-9.3 mmol/L) before medical treatment to 5.8 mmol/L (4.0 mmol/L-7.4 mmol/L). Five patients (7%) had complications from percutaneous nephrostomy including temporary atrial fibrillation in 3 patients and transient pyrexia in 2 patients.
Conclusions: Percutaneous nephrostomy as the initial management for hyperkalaemia from ureteric obstruction is a safe procedure with acceptable complication rates
