Rotary Brown Stock Pulp Washers through Mathematical Models: A Review

Increasing the accuracy of a model generally increases cost and decreases flexibility. The goal in creating a model is usually to obtain a Sufficiently accurate and flexible model at a low cost. Pulp and Paper making process involves many complex unit operations and process. The process of pulping and paper making is intensive with respect to row materials, energy, water and chemicals. If the plants are heat operated carefully it can also become pollution intensive. The key operation influencing the economy of the plant as well as controlling the pollution load is the washing process. Almost all the mills in the country use rotary vacuum washers for separating the black liquor from the pulp and for ensuring clean pulp to be available for downstream processing. The parameters which influence the operation of a brown stock washer are many and the phenomenon involved in the washing operation are complex. The present paper makes an attempt to look at the various parameters influencing the washing and look at various mathematical models used to predict the washer performance.

In vitro propagation oflemon balm (Melissa officinalis L.) through nodal bud culture of adult plant

A simple and efficient two step procedure for in vitro high frequency plant regeneration was developed for clonal propagation oflemon balm (Melissa officinalis) using nodal explants. Nitsch and Murashige and Skoog's medium supplemented with a-naphthalene acetic acid (1.0 mgl-1) supported axillary shoot growth and induction of roots in cultured explants. Nitsch medium showed better morphogenetic response than Murashige and Skoog's medium. Murashige and Skoog's medium fortified .with 2 mgP of either 6,benzyl aminopurine or 6-methyl aminopurine induced rapid proliferation of shoots. Rooting of the differentiated shoots was readily achieved with auxins fortified to Nitsch medium. The plantlets exhibited 80-90% success in establishment under glasshouse conditions. &nbsp

Management of Radiation Induced, Bilateral Primary THA Loosening with an Aseptic Paprosky Type IIB Acetabular Defect and a Contralateral Septic Type IIIB Acetabular Defect: A Case Report and Review of Literature

INTRODUCTION: Primary THA in an irradiated hip poses risk for early loosening and inadequate ingrowth. Adverse effects such as decreased vascularity and increased infection risk pose a threat. CASE PRESENTATION: Our patient was a case of post-irradiation (for cervical cancer) bilateral THA loosening causing aseptic acetabular loosening on one side and catastrophic septic loosening with a Paprosky type IIIB acetabular defect with pelvic discontinuity on the contralateral side. DISCUSSION: There have been various studies documenting deleterious effects of irradiation on osseoin-tegration and provide a challenge for long-term implant stability in THA patients. CONCLUSION: A meticulous treatment protocol with contemporary implant technology and staged bilateral stepwise management can lead to satisfactory clinical outcomes.This case report highlights on such specific nuances and principles

The Anachronistic Character of the Cuban Adjustment Act of 1966

The purpose of this study is to provide evidence that the Cuban Adjustment Act of 1966, the U.S. immigration policy that gives Cuban immigrants a unique advantage to permanently settle in the United States, is no longer working as intended. The policy was originally created to aid Cubans fleeing Fidel Castro’s communist regime and the nationalization of private industries, amongst other decrees. I provide this evidence through a set of six longitudinal analyses demonstrating the changing demographic and socioeconomic characteristics of Cuban immigrants between 1959 and 2014. Using data from U.S. Decennial Census and the American Community Survey, I show how the average age, percentage of males, educational attainment, percentage of white-collar workers, average personal income, and the percentage of self-identified whites have changed within the Cuban immigrant population during this time period. More specifically, my study finds that the likely profile of a Cuban émigré has evolved from a political refugee (a wealthy, college educated, white-collar worker) into what appears to be an economic émigré (middle class, no college education, blue-collar worker) between 1959 and 2014. My results substantiate the existing claim that Cuban immigrants have evolved from political to economic émigrés with quantitative evidence, thereby offering policymakers a compelling argument to revisit the outdated policy since it is no longer chiefly supporting political exiles. My findings offer an opportunity for further discussion to craft a new immigration policy with Cuba following the restoration of diplomatic relations in December of 2014.Bachelor of Art

A comparative study to determine the clinical efficacy of Ramipril versus combination of Ramipril and Telmisartan in reducing microalbuminuria associated with grade 2 hypertension

Inhibition of the renin-angiotensin system causes a reduction in urinary protein excretion. It is uncertain whether Angiotensin receptor blockers (ARBs) are equally effective antiproteinuric agents as Angiotensin converting Enzyme (ACE) inhibitors, or whether the combination of ACE inhibitors with ARBs is preferable to ACE inhibitor alone? Microalbuminuria is a prognostic marker for cardiovascular and renal risk. The objective of the study was to compare the clinical efficacy of Ramipril alone versus combination of Ramipril and Telmisartan by assessing the fall in B.P. and the improvement in the degree of microalbuminuria in stage II hypertensive patients. 60 patients of stage II hypertension without having any other cause of microalbuminuria were selected as subjects for the present study and were randomly distributed in to 2 groups- Group A included 30 patients who were given Ramipril 5 mg/ day and Group B included the same number of patients who were given a combination of Ramipril 5 mg/day and Telmisartan 40 mg/day. Baseline parameters included were measurement of Systolic, diastolic blood pressure and mean arterial pressure; microalbuminuria, blood urea, serum creatinine and serum potassium estimations. The drugs under trial were given for 20 weeks. Microalbuminuria was determined at 0 and 20 weeks. The mean percentage fall in microalbuminuria and mean arterial pressure were statistically highly significant (p<0.0001) with combination of Ramipril and Telmisartan (Group B) in comparison to Ramipril (Group A) alone. A highly significant (p‹ 0.0001) mean percentage increase in potassium level was observed in group B at the end of 20 weeks. The side effects were less observed in the combination group. Thus to conclude the combination of Ramipril and Telmisartan provides superior blood pressure (BP) lowering and target organ protection than Ramipril alone, hence the combination of Ramipril and Telmisartan is a better choice to treat and to prevent the progression of the disease.Keywords: Hypertension; Microalbuminuria; Ramipril; Telmisarta
