How to increase the operational efficiency on dry vacuuming service in Spotless cleaning Hamilton?
This research is based on Spotless private limited company. The organisation has various services within it, but this research is concentrated on its cleaning service, to increase the operational efficiency of dry vacuuming by surveying thirty workers regarding organisation, and interviewing the supervisor. This involves both quantitative and qualitative research so is a mixed method. The results gave a new perspective to the research. Initially the research started with one problem and ended up dealing with three problems. The research findings are that there is a need
• to increase the power and decrease the weight of vacuum machines.
• to give regular follow up training for workers
• to increase the number of permanent workers
The recommendation to the company to increase operational efficiency on their dry vacuuming service are: first step, to give training to the employees. Second step, to buy new vacuum machines, which have good power and weigh less. Third step, the company should start recruiting new permanent workers. By doing all the steps the company can out-shine its competitors, and increase the operational efficiency in dry vacuuming services
INVESTIGATING RHEOLOGICAL TECHNIQUES TO MODEL AND PREDICT OPERATING CONDITIONS OF A SINGLE SCREW EXTRUDER WITH INTERNAL RESTRICTIONS
Understanding rheology of raw materials and the numerous transformations they undergo is an essential aspect of modeling and predicting extrusion conditions. Both off-line capillary rheometry and in-line extruder fed rheometry techniques have been used to model rheology of materials during extrusion. Investigations on use of an off-line capillary rheometer to model apparent viscosity of full fat soy flours revealed inability of the capillary rheometer to handle food/biological materials high in oil content (20%) at high temperature (80C) and low moisture content (15% wet basis). The lack shear degradation in the capillary rheometer also resulted in over-prediction of corn flour viscosities at high temperatures (80 to 120C), shear rates (1 to 100 s-1) and low moisture contents (35 to 40%). A novel two-opening die attached to a small scale extruder operating at 100 to 300 rpm was used to measure in-line viscosities of cornmeal at 32.5 to 37.5% moisture during extrusion. Comparison of off-line versus in-line cornmeal viscosities at similar conditions consistently indicated that for food/biological materials sensitive to shear degradation, in-line viscosities were lower. Pasting property measurement revealed differences in material transformation which could be used to explain differences between techniques. Mechanistic model for the small-scal

Clinical presentations, management options and outcome in carcinoma of vulva.
INTRODUCTION :
Carcinoma vulva is a relatively rare disease accounting for 4% of all
gynecological malignancies in United States1. It constitutes 0.3% of all cancers
affecting females and 1.3% of all gynecological malignancies in Chennai2. The
vulva is the anatomic area immediately external to the vagina. It includes the labia
and the perineum. The inguinofemoral nodes are the sites of regional spread.
Tumor involvement of pelvic lymph nodes is considered distant metastasis.
OBJECTIVE : Carcinoma of the vulva is a relatively rare disease accounting for 0.3% of all
cancers affecting females and 1.3% of all gynecological malignancies in Chennai. Aim of the
present study is to analyze the clinical presentations, treatment options, morbidity, failure pattern
and survival for invasive carcinoma of vulva treated in our institution during a period of eight
years and to compare our results with other published series.
MATERIALS AND METHODS : Retrospective analysis of case records of 35 patients who
underwent surgery for invasive carcinoma of the vulva from 2004 to 2011 in the Department of
Surgical Oncology, Government Royapettah Hospital, Chennai.
RESULTS : The mean and median age was 52.5 years and 55 years respectively (range 21-72).
Labia majora was the predominant site of disease (80%). Twenty eight patients underwent
Radical Vulvectomy with Nodal Dissection, 2 underwent Hemivulvectomy with Nodal
Dissection, 2 underwent Simple Vulvectomy, 2 underwent Wide Local Excision and 1
underwent Wide Local Excision with Nodal Dissection. Lymphadenectomy was not done in 4
patients. With a median follow up of 26 months (range 2-67 months), 8 patients (22.9%)
developed recurrence, of which one is systemic, 4 regional and 3 local. The estimated 5 year
Overall Survival (OS) and Disease Free Survival (DFS) for all cases in our series using Kaplan-
Meier analysis was 85.1% and 65.4% respectively. On univariate analysis using log rank test,
advanced stage, lymph node positivity and lymph node positivity with extracapsular spread
(ECS) significantly affected estimated 5 year overall survival.
CONCLUSION : Carcinoma vulva, a relatively rare disease should better be managed in
dedicated cancer centers where treatment can be tailored to individual patients with
multidisciplinary cooperation. The median age in our series was 55 years which is well below the
western world. Extracapsular nodal spread was observed as the strongest prognostic factor for
survival in our series like other international series. Since there has been a dearth of reports
about this disease from our country as well as other developing countries we urge the need for
more studies from various centers and probably well designed multicentric studies keeping in
mind the low prevalence of this disease

A Study on Serum Fibrinogen as an Independent Predictor of Major Adverse Cardiac Events (MACE) in known Diabetic Coronary Artery Disease Patients
INTRODUCTION:
Diabetes Mellitus is one of the leading cause of
morbidity and mortality worldwide. Its Prevalence is
gearing up at a faster pace all over the world especially in developing countries like India. It is the most important risk factor in the pathogenesis of Acute Coronary syndrome. Coronary artery disease is one of the most common Macro vascular complications of Diabetes, especially Type 2 diabetes. It is the leading cause of mortality and morbidity in diabetes.
In addition, diabetic patients are likely to have Poor
treatment outcome compared with non-Diabetic controls. Its occurrence is increasing in younger age group,causing
premature coronary artery disease and premature death
inflicting economic burden to the family and to the society.
Recently studies are focussing on serum Fibrinogen
and its role in the pathogenesis of Coronary artery disease in Diabetes. Fibrinogen being an acute phase reactant is also a pro-coagulant. It plays a major role in coagulation of blood. It has a significant role in Athero-thrombosis. Hence its role in adverse cardiac events in Diabetics and its prognostic value is currently the study of interest.
AIMS & OBJECTIVES:
1. To determine the concentration of Fibrinogen in
diabet ic CAD and its causal relationship to adverse
cardiac events.
2. To ascertain serum fibrinogen‟spredictive value of
major adverse cardiac events in Diabetic CAD.
3. To ascertain the prognostic value of serum fibrinogen
in Diabetic patients presenting with subs equent major
adverse cardiac events.
4. To evaluate the relation between serum Fibrinogen
and other factors that cause adverse cardiac events.

correlates with increase in serum fibrinogen titres
Multilinear transference of Fourier and Schur multipliers acting on non-commutative -spaces
Let be a locally compact unimodular group, and let be some
function of variables on . To such a , one can associate a
multilinear Fourier multiplier, which acts on some -fold product of the
non-commutative -spaces of the group von Neumann algebra. One may also
define an associated Schur multiplier, which acts on an -fold product of
Schatten classes . We generalize well-known transference results
from the linear case to the multilinear case. In particular, we show that the
so-called `multiplicatively bounded -norm' of a multilinear
Schur multiplier is bounded above by the corresponding multiplicatively bounded
norm of the Fourier multiplier, with equality whenever the group is amenable.
Further, we prove that the bilinear Hilbert transform is not bounded as a
vector valued map , whenever and are
such that . A similar result holds for
certain Calder\'on-Zygmund type operators. This is in contrast to the
non-vector valued Euclidean case.Comment: v3 incorporates reviewer comments and suggestions. To appear in the

MAGNETIC POLE REPULSIVE DAMPER (MPRD): A PROMISING SOLUTION FOR SEISMIC PROTECTION OF STRUCTURES
Owing to its high energy dissipation characteristics, the passive damper is an effective means of mitigating natural hazards for structures. In this study, a novel magnetic pole repulsive damper (MPRD), designed for reducing structural responses during natural hazards such as earthquakes, was developed and its performance was validated. The MPRD is an effective solution for seismic protection that works on the principle of magnetic repulsion and has a higher energy dissipation capacity than conventional dampers. The MPRD was fabricated using mild steel, neodymium magnets, and a set of helical springs. Two scaled reinforced concrete frames were tested using a 50 kN loading actuator. One frame was equipped with the MPRD, while the other served as a conventional frame for comparison. The frame with the MPRD showed reduced displacements. Compared with the conventional frame, that with the MPRD exhibited an increase in load of 40 % and an increase in energy dissipation of 6,44 %. Further, an increase in lateral stiffness, a 19,23 % increase in stiffness degradation, and changes in crack patterns were observed in the frame with MPRD compared to the conventional frame. The study\u27s success in validating the MPRD performance in reducing structural responses in moderate to high seismicity regions makes it a promising solution for building seismic protection.
