The object of development is the central heating point of a multi-section residential complex.
The purpose of the work is to design a central heating system with calculations for the provision of hot water supply and heating system for a multi-section residential building, which is a very important part for the design of the residential complex.
Calculations of loads from consumers for hot water supply and heating in winter, transition and summer periods are given. Calculations of heat carrier losses in cold, transitional and warm periods of the year are performed. Hydraulic calculation of heating network pipelines with selection of diameters and calculation of pressure losses is made. Calculations of plate heat exchangers for the hot water supply system unit and the heating system unit were performed.
The heating point, located in the basement of the 2nd residential section, is designed for the distribution of thermal energy between the heating and hot water supply systems of the 2nd, 3rd, 4th sections. Heating system - two-pipe, water. Heat supply source - ST-1 TM-1 thermal networks CHP - 5.Connection node - TC 101A \ 21. According to the results of calculations, pumps with wet rotorswere selected.

Prediction of seroconversion in relation to HBsAG quantification in chronic HBV patients.
INTRODUCTION :
There are approximately 400 million hepatitis B virus (HBV)
carriers in the world. Till 1981, hepatitis B patients relied on serology
assays (1). “E” antigen (HBeAg) was a marker of infectivity. Initially
assays to quantify HBV DNA polymerase activity was done and later only
HBV DNA level estimation could be done. Method used was hybridization
techniques. Spontaneous e antigen seroconversion is seen in the course of
chronic HBV infection.
Course of B positive individuals had 2 stages as defined initially.
First stage has e antigen, and HBV DNA detectable. Second stage does not
have HBeAg, immeasurable DNA, and passive liver disease. Second stage
patients are “healthy” carriers who are non replicative.
AIM :
1. To predict the HBeAg seroconversion in relation with HBsAg quantification in patients with chronic HBV infection with antiviral treatment.
2. Clinical profile of Chronic HBV infection.
3. Clinical response of Chronic HBV infection patients with antiviral
drug in a Tertiary centre.
MATERIALS AND METHODS :
It is a prospective study conducted between October 2010 and April
2012 where consecutive patients with the diagnosis of Chronic HBV
infection undergoing medical treatment with antiviral Telbivudine from
our hospital were included. During this period patients started on treatment
for compensated CHB infection are included in this study.
A written consent was obtained from all the patients. Institute ethical
committee has approved the study. All patients with compensated CHB
patients were included in the study. All patients underwent a detailed
clinical evaluation at entry, with the following data:
Age, gender, duration of illness, details of treatment prior to
registration. Baseline demographic details such as age, gender, literacy,
socio economic status, alcohol intake, smoking, religion and occupation
were collected. Patient had baseline investigations such as Complete blood
count, Liver function test, Prothrombin time, International normalized
ratio, renal function test, HBsAg, Anti-HCV, ultra sonogram and
endoscopy.
CONCLUSION :
In conclusion, results of our study indicate that HBsAg
quantification is a good predictor of HBeAg seroconversion .Values for
the HBsAg quantification from this study need to be validated by
randomised prospective studies . Other parameters like age , vertical
transmission and baseline ALT levels were not significant.
Applying HBsAg quantification though may not be cost effective it
appears to be a good predictor for e antigen seroconversion but further
randomised studies are needed to evaluate the accurate prediction of e
antigen seroconversion in our population
Heat Transfer Vest
The purpose of this report is to document the progression of the authors senior project. . The of that project was the research of Liquid Cooled Garment (LCG) technology, the generation of a novel LCG prototype and the testing of that prototype relative to a commercial benchmark. As such, this report is a complete narrative of the of these tasks, their execution and the underlying assumptions and commentary. The motivation for this report is to satisfy the capstone requirements of the MET program at CWU by documenting the Senior Project and its subordinate tasks. First, the student designed a LCG system based on the knowledge gained from his coursework and independent research. Two water-circulating vests were constructed from copper tubing, and a third military-surplus device was purchased from Ebay. All three were tested using a sample set of college aged males performing routine exercises. Afterward, the test subjects were served with a likert-scale survey and short-answer questions, so that the qualitative properties of the vests could be recorded. It was determined that the benchmark vest had a superior heat transfer effect, but the optimization of the copper vests produced an end product that was more comfortable than the initial prototype and had a greater perceived effectiveness than the benchmark
The Effect of Ice Formations on Propeller Performance
Measurements of propeller efficiency loss due to ice formation are supplemented by an analysis to establish the magnitude of efficiency losses to be anticipated during flight in icing conditions. The measurements were made during flight in natural icing conditions; whereas the analysis consisted of an investIgation of changes in blade-section aerodynamic characteristics caused by ice formation and the resulting propeller efficiency changes. Agreement in the order of magnitude of eff 1- ciency losses to be expected is obtained between measured and analytical results. The results indicate that, in general, efficiency losses can be expected to be less than 10 percent; whereas maximum losses, which will be encountered only rarely, may be as high as 15 or 20 percent. Reported. losses larger than 15 or 20 percent, based on reductions in airplane performance, probably are due to ice accretions on other parts of the airplane. Blade-element theory is used in the analytical treatment, and calculations are made to show the degree to which the aerodynamic characteristics of a blade section. must be altered to produce various propeller efficiency losses. The effects of ice accretions on airfoil-section characteristics at subcritical speeds and their influence on drag-divergence Mach number are examined, and. the attendant maximum efficiency losses are computed. The effect of kinetic heating on the radial extent of ice formation is considered, and its influence on required length of blade heating shoes is discussed. It is demonstrated how the efficiency loss resulting from an icing encounter is influenced by the decisions of the pilot in adjusting the engine and propeller controls
