This paper provides details and the results of an evaluation study carried out on the largest residential demand management program in Australia, the Sydney Water Corporation (SWC) ‘Every Drop Counts’ (EDC) residential retrofit program. The evaluation measured the water savings of program participants and compared them to a control group. Savings of 20.9 ± 2.5 kilolitres per household per annum (kL/hh/a) were found from statistical analysis of water meter readings of the sample of single residential households analysed. These individual savings effectively provide SWC with a potential total saving of 3,344 ± 400 megalitres per annum (ML/a) for the single residential houses retrofitted alone, i.e. 80% of the 200,000 households retrofitted to date. The evaluation identified that no ‘decay’ in average savings were found over the maximum four year period assessed. Other factors evaluated during the study included: analysis of individual water efficiency measures; comparison of savings with other evaluations; and savings related to occupancy ratio, geographical grouping, income category and defined socioeconomic categories.

Regional Water

The Sacramento California Region has long enjoyed ample water supplies and popular rivers providing esthetic, recreation and environmental resources. Ground and surface water supplies have been managed by twenty independent management agencies. In the 1980s and 1990s the region experienced dramatic population growth and increased water demand. Environmental organizations sought to preserve the environmental values of the Lower American River. Six years of negotiation resulted in the Water Forum Agreement, a memorandum of understanding signed by business and agricultural leaders, citizens groups, environmentalists, water managers, and local governments to fulfill two co-equal objectives: (i) to provide a reliable and safe water supply for the region's economic health and planned development to the year 2030; and (ii) to preserve the fishery, wildlife, recreational, and aesthetic values of the Lower American River. This paper describes three major parameters guiding the water future of the Sacramento Region, which may be a model for other regions of the world: (1) the seven policy elements of the Water Forum Agreement; (2) the Regional Water Authority (RWA) and the Sacramento Groundwater Authority help to implement the policies of the Water Forum Agreement; (3) RWA's regional water efficiency program provides “pick and choose” water efficiency measures to twenty water suppliers in three counties.

This study aims to determine the effect giving of ethylacetate fraction of leather  purple sweet potato (Ipomoea batatas (L.) Lam, on levels of malondialdehyde (MDA) serum in mice hyperglicemia were induced with streptozocin dose of 50 mg/kgBW. Mice were divided into 5 groups, each group consisting of 3 tails, group I is a negative control, group II is a positive control, group III,IV and V is given ethylacetate fraction a dose of 100 mg/kgBW, 300 mg/kgBW, and 600 mg/kgBW. Ethyl Acetate Fraction leather purple sweet potato given orally for 15 days after the animal is declared hyperglicemia and measurement of blood glucose levels on 5, 10, and 15 day after giving test preparation in animal experiments. On the 16 day throughout the mice were taken serum levels measured malondialdehid. The statistical analysis results showed that giving of ethyl acetate fraction of leather purple sweet potato at a dose of 100 mg/kgBW, 300 mg/kgBW, and 600 mg/kgBW can lower blood glucose levels in mice hyperglycemia significantly (p<0.05). Malondialdehid levels on average in each group is 1.35 nmol/ml, 3.00 nmol/ml, 2.72 nmol/ml, 2.20 nmol/ml and 2.61 nmol/ml, the results of statistical analysis showed a decrease in melondialdehid serum levels were significantly (p<0.05), where a dose of 300 mg/kgBW is an effective dose for lowering blood glucose levels followed by decreased levels of malondialdehid which give effect approaching negative control.

We compared the prevalence of ultrasound signs of adenomyosis in women with endometriosis who underwent surgery to those who were managed conservatively. This was a retrospective study of women evaluated at a tertiary endometriosis referral center who underwent 2D/3D transvaginal ultrasound. Adenomyosis diagnosis was based on the presence of at least three sonographic signs. The study group subsequently underwent laparoscopic surgery while the control group continued conservative management. Statistical analysis compared the two groups for demographics, symptoms, clinical data, and sonographic findings. The study and control groups included 244 and 158 women, respectively. The presence of any, 3+, or 5+ sonographic signs of adenomyosis was significantly more prevalent in the study group (OR = 1.93–2.7, p < 0.004, 95% CI; 1.24–4.09). After controlling for age, for all findings but linear striations, the OR for having a specific feature was higher in the study group. Women in the study group with ≥ 5 sonographic signs of adenomyosis had more than twice the risk of experiencing infertility (OR = 2.31, p = 0.012, 95% CI; 1.20–4.45). Sonographic signs of adenomyosis are more prevalent in women with symptomatic endometriosis who underwent surgery compared with those who continued conservative management. Women with 5+ findings have a significantly increased risk of infertility. Adenomyosis on ultrasound should be considered in the management decisions regarding these patients.

Research Questions

In this article, we describe a practical implementation of a serious game to facilitate knowledge acquisition about renewable energy technologies among youngsters, using the game Serena Supergreen and the Broken Blade. We present the quest design and an evaluation study on the research questions: (a) Did youngsters who played the game have more knowledge about renewable energy technologies compared to those who did not play the game? (b) How did students perceive the game? (c) What did the students recall from the game 11 months after playing it? The study was conducted at a German secondary school ( n = 82). Youngsters who played the game had more knowledge on renewable energy technologies compared to the control group ( n = 31). In a second round of data collection, 11 months after playing, a majority of students still remembered the game quests. Our results indicate that serious games are a promising approach for introducing basic knowledge about renewable energy technologies.

Forty-three full-term infants have been studied with respect to hemolysis of erythrocytes in solutions of hydrogen peroxide and concentrations of bilirubin in the serum. Mean values for concentration of bilirubin in the serum and percentage of hemolysis followed similar patterns in the first few days of life. However, statistical analysis of the data in individual cases showed no significant correlation between the degree of hemolysis in solutions of hydrogen peroxide and the concentrations of bilirubin in the serum. Administration of vitamin E prevented an increase in hemolysis of erythrocytes in solutions of hydrogen peroxide but failed to produce any significant change in concentrations of bilirubin as compared with the control group. The evidence suggests that the relative deficiency of vitamin E which exists in most newborn infants does not play a part in the causation or maintenance of physiologic hyperbilirubinemia. The clinical significance of increased hemolysis of the erythrocytes of the newborn infant in solutions of hydrogen peroxide remains a mystery. Possible approaches to the clarification of this problem are suggested.

The objective: study of hormonal status in pregnant women with benign cervical pathology (CP) in anamnesis. Patients and methods. Clinical and statistical analysis of the hormonal status of 100 women with a history of benign CP pathology has been performed. According to the revealed symptoms of CP during colposcopic examination, women were divided into two groups: 100 pregnant women, in whom colposcopic and cytologically signs of CP pathology were not detected, were included in the control group; and 100 women who had a pathology of CP, entered the main group. Results. The study examined hormonal relationships in the system mother–placenta–fetus, namely the level of hormones such as estriol, progesterone, human chorionic gonadotropin, placental lactogen. Hormonal changes in pregnant women and contribute to reducing the immunoreactivity unwanted stimulation of existing benign hyperplastic background processes in the cervix. Conclusion. Determining functional state placenta is an important factor in the timely diagnosis of disorders in the functioning of the system mother–placenta–fetus. Key words: hormonal status, placenta, uterine cervix, fetoplacental complex.

Background: Previous studies support the efficacy and effectiveness of face-to-face group-based fatigue management education for people with multiple sclerosis (MS). Nevertheless, many people are unable to access these programs due to environmental barriers. Objectives: To test the efficacy and effectiveness of a group-based, teleconference-delivered fatigue management program for people with MS. Methods: A randomly allocated two-group time series design with a wait-list control group was used. In total 190 participants were allocated (94 intervention, 96 wait-list control). Primary outcomes (fatigue impact, fatigue severity, health-related quality of life (HRQOL)) were measured before, immediately after, at 6 weeks, 3 months, and 6 months post. Secondary outcome (self-efficacy) was measured at the same points. Effectiveness (intent-to-treat) and efficacy (per protocol) analyses were conducted. Results: The program was more effective and efficacious than control for reducing fatigue impact but not fatigue severity. Before and after comparisons with the pooled sample demonstrated efficacy and effectiveness for fatigue impact, fatigue severity, and 6 of 8 HRQOL dimensions. Changes were maintained for 6 months with small to moderate effect sizes. Conclusion: The results offer strong support for the viability of teleconference-delivered fatigue management education for enabling people with MS to manage this disabling symptom.
