Abstract
Red alder (Alnus rubra Bong.) is well recognized as an effective host plant for the symbiotic fixation of N. While this fixation process leads to the rapid accumulation of N within the ecosystem, it also enhances nutrient accumulation in biomass and soil organic matter and increases nitrification and cation leaching. We hypothesized that changes in soil properties resulting from these processes would decrease site productivity for second rotation red alder. Adjacent stands of 55 yr old alder and Douglas fir (Pseudotsuga menziesii [Mirb.] Franco) were studied at the Thompson Research Center on the Cedar River Watershed in western Washington, USA. The presence of red alder caused the following soil changes: decreased soil solution pH, increased CEC, increased exchangeable acidity accompanied by a decreased soil pH and base saturation. This decreased soil and soil solution pH resulted in increased Al concentration in the soil solution and on exchange sites as well as decreased P availability. To determine the effect of these changes on the productivity of the 2nd rotation alder forest, a species conversion experiment was initiated 5 yr ago. Results from this conversion study clearly indicated that the first rotation red alder forest has caused a relative decrease in the productivity of the second rotation red alder plantation. Compared to the growth of red alder on the former Douglas fir site, the second rotation red alder on the former red alder site exhibited 33% less height growth and 75% less aboveground biomass accumulation after 5 yr. Future research will focus on identifying those factors causing this lower productivity including P availability, soil acidity and Al toxicity, cation availability, and competition with other vegetation.

Abstract
PIP: Contraception should be integrated into maternity care programs and made accessible to postpartum women to prevent unwanted pregnancies. The advantages of integrating family planning and maternal care services include a cost-effective operation by employing current resources and staff and contraceptive distribution to women who otherwise may have no access to contraceptive methods. 2 key factors for such a program are timing and counseling. Educating women about contraception should begin during prenatal visits; pregnant women could be advised concerning appropriate methods and proper timing to begin contraceptive usage after birth. Furthermore, rural women would benefit by family planning services providing prenatal care and family planning counseling. Understanding cultural factors associated with resuming sexual activity after birth is also important in implementing successful contraceptive services. In some cultures, sexual activity is disfavored for a designated period of time after giving birth; thus, a delay in beginning contraceptive usage may not pose a problem until sexual relations are resumed. Counseling would provide information regarding available contraceptive methods as well as the effectiveness of breastfeeding as a natural means of postpartum contraception.

Abstract
Dental plaques of 36 smokers of cigarettes, shisha and ghoza with a mean age of 35.4 years As well as those of a control group of 23] non smokers of similar age were investigated to study their aerobic microflora, The specimen were taken from So dental plaque. Their bacterial population was estimated. Smoker! using cigarette had the lower score gingivitis 0-2] while those using shisha and ghoza had higher score 3-4] as compared with control group. showing Zero-1] score. The type of organisms en countered in smokers was not markedly different from that in not smokers but their numbers varied a lot. However, streptococci diphtheroids and micrococci took the upper hand in the latter while lactose and non lactose fermenting gram ve bacilli and Candida tropicalis were absent from such samples. Higher counts of fungi were noted in smokers in general and those of shisha i ghoza in particular. Association of high numbers of yeasts and bacteria was noted in 19/36 and 5/23 of smokers and non smokers respectively. Three types of yeasts were isolated C. albicans C. tropicalis saccharomyces cervicae. While filamentous fungi represented by aspergillus and penicillium spp. It was obviom from that when there was rise in number of fungi iii smokers number of bacteria was simulataneouly increased as well

Abstract
Asbestos cement pipes are in urgent demand for replacement because of the high frequency of failures. In response to this demand, The Japan Water Pipe Systems Research Center is developing diagnostic methods for asbestos cement pipes aiming at contributing to timely and effective replacement. Three methods have been studied: (1) Direct diagnosis (using 10 types of inspection method), (2) Indirect diagnosis based on statistical analysis (2 types of method), and (3) Diagnosis based on measured data. This wide selection of diagnoses is being narrowed down to the most beneficial and sensible approaches.

Abstract
Nutrification in chloraminated drinking water can have a number of adverse effects on water quality, including a loss of total chlorine and ammonia-N and an increase in the concentration of heterotrophic plate count bacteria and nitrite. To understand how nitrification develops, a study was conducted to examine the factors that influence the occurrence of ammonia-oxidizing bacteria (AOB) in a chloraminated distribution system. Samples were collected over an 18-month period from a raw-water source, a conventional treatment plant effluent, and two covered, finished-water reservoirs that previously experienced nitrification episodes. Sediment and biofilm samples were collected from the interior wall surfaces of two finished-water pipelines and one of the covered reservoirs. The AOB were enumerated by a most-probable-number technique, and isolates were isolated and identified. The resistance of naturally occurring AOB to chloramines and free chlorine was also examined. The results of the monitoring program indicated that the levels of AOB, identified as members of the genus Nitrosomonas, were seasonally dependent in both source and finished waters, with the highest levels observed in the warm summer months. The concentrations of AOB in the two reservoirs, both of which have floating covers made of synthetic rubber (Hypalon; E.I. du Pont de Nemours and Co., Inc., Wilmington, Del.), had most probable numbers that ranged from 300/ml and correlated significantly with temperature and levels of heterotrophic plate count bacteria. No AOB were detected in the chloraminated reservoirs when the water temperature was below 16 to 18°C. The study indicated that nitrifiers occur throughout the chloraminated distribution system. Higher concentrations of AOB were found in the reservoir and pipe sediment materials than in the pipe biofilm samples. The AOB were approximately 13 times more resistant to monochloramine than to free chlorine. After 33 min of exposure to 1.0 mg of monochloramine per liter (pH 8.2, 23°C), 99% of an AOB culture was inactivated. The amounts of this disinfectant that are currently used (1.5 mg/liter at a 3:1 ratio of chlorine to ammonia-N) may be inadequate to control the growth of these organisms in the distribution system.

Abstract
The authors investigated indoor thermal environment, airtightness, indoor air quality, and energy consumption in thirteen new houses of wood-frame construction in a local city in Japan in the winter of 1985. All houses had thermally-insulated walls, ceilings, and floors, except for one house which had a concrete floor without insulation under the floor. Eight houses had concrete floors on the first level of the structure. Seven houses out of eight had hot-water pipes embedded in the concrete for floor heating and thermal insulation under the floor on the grade. Three houses out of seven also had fan coil units in the bedrooms on the second floor. The six other houses without floor heating had oil or gas local space heaters. The authors found differences in temperature profiles between the houses with floor heating and those with space heaters. The effective leakage area per floor area obtained by the fan pressurization method was distributed from 3.8 to 16 cm2/m2. The concentration measurements of CO2 and NO2 in the living rooms showed that the two houses with unvented oil space heaters were more polluted than the other houses. The total annual amount of energy consumption was distributed from 46 to 100 GJ.

Abstract
A review of patients with Legionnaires' disease hospitalized in our Clinic from the first cases recorded in 1978 up to now has been given. The diagnosis was confirmed by indirect immunofluorescent method in 23 patients with pneumonia, using antigen and method of the Center for Disease Control Biological Products Division, Atlanta, Georgia, USA (Dr Wilkinson). Most of the patients (16) were sporadic cases and twice as less cases were from two epidemics (7). Two patients among sporadic cases developed a very severe form of the disease during the immunosuppressive therapy after kidney transplantation. Clinical, epidemiological and laboratory data of 10 patients hospitalized and treated during the last three years (1986-1988) were analyzed in details. Two thirds of these patients were above 40 years of age and the youngest one was 29 years old. Except the advanced age no other firm disposable factor was found in patients belonging to sporadic cases. In cases from epidemics the source of infection was probably water from water-pipes i.e. hotel devices (bathrooms, douches, drinking water, air-conditioning units, water used in kitchen for cooking etc). All patients recovered after a longer symptomatic and antibiotic treatment. Erythromycin and rifampicin were applied the most frequently. In some patients treatment with chloramphenicol was effective.

Abstract
Inner Ear Decompression Sickness (IEDCS)--manifested by tinnitus, vertigo, nausea, vomiting, and hearing loss--is usually associated with deep air or mixed gas dives, and accompanied by other CNS symptoms of decompression sickness (DCS). Early recompression treatment is required in order to avoid permanent inner ear damage. We present an unusual case of a scuba diver suffering from IEDCS as the only manifestation of DCS following a short shallow scuba dive, successfully treated by U.S. Navy treatment table 6 and tranquilizers. This case suggests that diving medical personnel should be more aware of the possible occurrence of IEDCS among the wide population of sport scuba divers.

Abstract
The study was performed on 50 adult male cigarette and hubble smokers. The aim was to study and compare the cigarette and hubble bubble smoke on some chemical and biological functions of the smoke component. Plasma epinephrine, glucose, lactate/pyruvate ratio, growth hormone, free fatty acids, and cortisol were significantly higher in smokers than non smokers especially cigarette smokers. Plasma insulin concentration showed a significantly delayed response to the increased blood glucose. Plasma proteins, urea, pyruvate, creatinine and vitamin B12 were significantly reduced inn smokers than non smokers especially cigarette smokers. Both blood erythrocytes and leucocytes were increased significantly in smokers. Blood gases showed significantly low PaO2, significant blood level of Co fraction, while PaCO2 was unaffected. Urinary catecholamines were significantly higher in smokers especially in cigarette smokers

Abstract
It is necessary for waterworks department to strengthen its financial foundation in order to supply the clean water stably. The hydraulic power generation utilizing waterworks facilities contributes greatly to the saving energy as well as the saving expenditures. But we have to consider carefully the problem in introducing the generation equipment into existing waterworks system and have to take some countermeasures against the problem. The problem is mainly the water quality pollution, water hammering and accidents with generation equipment. Further we have to consider the usage of generated energy for increasing the profit of this power generation project.
