Effects of Cu2+ and Cd2+ Stress on Growth and POD Activity of Tomato Seedling

The growth situation and peroxidase （POD） of seedlings of two tomato cultivars were investigated under the stress of different concentrations of Cu^2＋ and Cd^2＋ . The toxicity differences of Cu^2＋ and Cd^2＋ to tomato seedlings and the corresponding differences between two tomato cultivars were observed through the stress trial with the ahove two heavy metal ions, The resubs showed that low concentration of Cu^2＋ and Cd^2＋ could promote the growth and could enhance the POD activity of tomato seedlings, while high concentratiun Cu^2＋ and Cd^2＋ could inhibit seedling growth and POD activity of tomato seedlings. Cd^2＋ functioned more obviously than that of Cu^2＋ , two tomato cultivars also presented difference in response to heavy metal stress.

Methane production and small intestinal bacterial overgrowth in children living in a slum

AIM:To analyze small intestinal bacterial overgrowth in school-aged children and the relationship between hydrogen and methane production in breath tests.METHODS:This transversal study included 85 children residing in a slum and 43 children from a private school,all aged between 6 and 10 years,in Osasco,Brazil.For characterization of the groups,data regarding the socioeconomic status and basic housing sanitary conditions were collected.Anthropometric data was obtained in children from both groups.All children completed the hydrogen(H 2) and methane(CH 4) breath test in order to assess small intestinal bacterial overgrowth(SIBO).SIBO was diagnosed when there was an increase in H 2 ≥ 20 ppm or CH 4 ≥ 10 ppm with regard to the fasting value until 60 min after lactulose ingestion.RESULTS:Children from the slum group had worse living conditions and lower nutritional indices than children from the private school.SIBO was found in 30.9%(26/84) of the children from the slum group and in 2.4%(1/41) from the private school group(P = 0.0007).Greater hydrogen production in the small intestine was observed in children from the slum group when compared to children from the private school(P = 0.007).A higher concentration of hydrogen in the small intestine(P < 0.001) and in the colon(P < 0.001) was observed among the children from the slum group with SIBO when compared to children from the slum group without SIBO.Methane production was observed in 63.1%(53/84) of the children from the slum group and in 19.5%(8/41) of the children from the private school group(P < 0.0001).Methane production was observed in 38/58(65.5%) of the children without SIBO and in 15/26(57.7%) of the children with SIBO from the slum.Colonic production of hydrogen was lower in methaneproducing children(P = 0.017).CONCLUSION:Children who live in inadequate environmental conditions are at risk of bacterial overgrowth and methane production.Hydrogen is a substrate for methane production in the colon.

Have guidelines addressing physical activity been established in nonalcoholic fatty liver disease?

The purpose of this review was to highlight, in relation to the currently accepted pathophysiology of non-alcoholic fatty liver disease (NAFLD), the known exercise habits of patients with NAFLD and to detail the benefits of lifestyle modification with exercise (and/or physical activity) on parameters of metabolic syndrome. More rigorous, controlled studies of longer duration and defined histopathological end-points comparing exercise alone and other treatment are needed before better, evidence-based physical activity modification guidelines can be established, since several questions remain unanswered.

Biomass and microbial activity in a biofilter during backwashing

Biomass and microbial activity in backwashing processes of a biofilter for tertiary treatment were investigated. The microbial groups revealed new distribution along the biofilter depth after low flow rate backwashing for a short time. Then the start-up process was accelerated by backwashing. The biomass profile and microbial activity profile both varying with depth before and after backwashing, can be mathematically described by quadratic equations. Using the profiles, the difference of oxygen demand can be calculated to determine the airflow rate during backwashing. Combined with the difference between biofilters and rapid gravity filters, analysis of biomass and microbial activity can determine more accurately the required airflow rate during backwashing.

Teaching Religious Education in Schools and Adolescents＇ Social and Emotional Development. An Action Research on the Role of Religious Education and School Community in Adolescents＇ Lives

The presentation of the findings of this article is based on an action research focused on the supportive role of the school in adolescents＇ lives, whereby Religious Education＇s contribution to the social and emotional development of adolescents （11-15） is combined with the evaluation of the potential offered by a constructivist approach to the learning process. The research commenced in 2012 and is now in its third ＂year. The project is based on an intervention at a high school in an impoverished suburb of Athens and researches educational practices through interpretative-ethnographic methods. The researcher has attempted to answer the question of whether the design of the learning environments is effective not only in the learning process, but also on inter-communication and ＂connectedness＂ between the members of the learning community. The findings so far indicate a correlation between adolescents＇ emotional and social wellbeing and the school＇s approach to knowledge and learning methods, specifically in Religious Education classes. It is fair to say, however, that there exist ethnic, social and family components that are negatively related to a sense of＂connectedness＂ within the school although at the same time Religious Education as a subject is, however, found to be positively related to learning community atmosphere.

An Innovative Process to Improve Turbidity and Organics Removal by BAC Filters

The turbidity criterion for the product water of a WTP according to the State Project ‘863’ on the safeguard technology of drinking water in the southern areas of China is 0.1 NTU. The turbidity removal in the activated carbon filter was analyzed in a pilot-scale test and an innovative technology to improve the turbidity removal in a biologically activated carbon (BAC) filter was put forward in order to meet the criterion. Experimental results showed that the enhanced filtration by adding polymerized aluminium chloride (PAC) into the BAC filter was quite effective in turbidity control. The effluent turbidity was kept at a stable level (mean) of 0.033 NTU with a high removal of about 80% for influent turbidity of 0.110-0.240 NTU with an addition of PAC at 0.05 mg L -1, meeting the requirement for filtrate turbidity equal to or less than 0.1NTUC totally. In addition, the larger the PAC dosage was, the lower the effluent turbidity was. However, further improvement of turbidity removal was not obvious for PAC dosages beyond 0.10 mg L -1, and an optimal PAC dosage in the range of 0.]05-0.10 mg L -1 was proposed.

Somatic embryogenesis and peroxidase activity of desiccation tol-erant mature somatic embryos of loblolly pine

White, translucent, glossy mucilaginous callus was initiated from the mature zygotic embryos explants on callus induction medium with 2,4-D, BA, and kinetin in the 3-9th week of culture. This type of callus induction occurred at a lower fre-quency with either a-naphthaleneacetic acid (NAA) or IBA (both 8 mg/L). White, translucent, glossy mucilaginous callus was embryogenic and mainly developed from the cotyledons of the mature zygotic embryo. Somatic embryos were formed on dif-ferentiation medium. Desiccation tolerance can be induced by culturing somatic embryos of loblolly pine (Pinus taeda L.) on medium supplemented with 50 mm abscisic acid (ABA) and/or 8.5% polyethylene glycol (PEG6000). Scanning electron micros-copy of desiccated somatic embryos showed that the size and external morphology of the desiccation tolerant somatic embryos recovered to the pre-desiccation state within 24-36 h, whereas the sensitive somatic embryos did not recover and remained shriveled, after the desiccated somatic embryos had been rehydrated. Peroxidase activity of desiccated somatic embryos in-creased sharply after 3 days of desiccation treatment, and desiccation tolerant somatic embryos had higher peroxidase activity compared to sensitive somatic embryos. Higher peroxidase activity of desiccation tolerant somatic embryos was possibly ad-vantage of catalyzing the reduction of H2O2 which was produced by drought stress, and protecting somatic embryos from oxida-tive damage.

Risk factors for accidental falls in the elderly and intervention strategy

As the population ages, older people's health and quality of life are becoming a matter of public concern increasingly. Through review of the literatures and analysis of the reasons for falls in older people, we worked out some measures to cope with such a situation, provided the self-care knowledge of falls prevention for older people and improved the quality life of older persons. The recovery process is long, if the old people fall down, which brings a lot of inconvenience to individuals and families, and it can also cause a lot of complications. If wary of fall risk factors, the quality of life of older persons can be improved. According to the different conditions of the elderly, we should take effective measures to create suitable living environment for senior citizens, and propagandize the knowledge of the old people's health care, which has the great significance in preventing the elderly's fall, and improving their living quality.

Living （on） Archaeological Sites in Turkey： Engagement of Local Communities into Decision Making Process

Archeological sites have been considered as ＂dead＂ sites consisted from building remain buried into ground in modern heritage management doctrines for a long period. Thus their conservation policies are mainly shaped according to this Western perspective. After the spread of international doctrines in conservation of cultural heritage to other parts of the world, it was realized that some archaeological sites were more than group building remains. They were pilgrim sites for the local communities continuously for centuries onwards. Even in some cases, they have traditional management systems to take care for the site. This has raised the awareness about the gaps in modern heritage conservation approaches. International organizations have mentioned about the involvement of local groups in heritage management systems considering their traditional and cultural association with the cultural site. This has provided shifting of conservation approaches from conventional approaches towards living heritage approach in such delicate cultural heritage sites. The purpose of this paper is to discuss the historic generation of policies towards local communities living on archaeological sites in Turkey comparing the policies between living （on） archaeological sites and living archaeological sites approach.

Effect of a biological activated carbon filter on particle counts

Due to the importance of biological safety in drinking water quality and the disadvantages which exist in traditional methods of detecting typical microorganisms such as Cryptosporidium and Giardia, it is necessary to develop an alternative. Particle counts is a qualitative measurement of the amount of dissolved solids in water. The removal rate of particle counts was previously used as an indicator of the effectiveness of a biological activated carbon (BAC) filter in removing Cryptosporidium and Giardia. The particle counts in a BAC filter effluent over one operational period and the effects of BAC filter construction and operational parameters were investigated with a 10 m3/h pilot plant. The results indicated that the maximum particle count in backwash remnant water was as high as 1296 count/ml and it needed about 1.5 h to reduce from the maximum to less than 50 count/ml. During the standard filtration period, particle counts stay constant at less than 50 count/ml for 5 d except when influ- enced by sand filter backwash remnant water. The removal rates of particle counts in the BAC filter are related to characteristics of the carbon. For example, a columned carbon and a sand bed removed 33.3% and 8.5% of particles, respectively, while the particle counts in effluent from a cracked BAC filter was higher than that of the influent. There is no significant difference among particle removal rates with different filtration rates. High post-ozone dosage (>2 mg/L) plays an important role in particle count removal; when the dosage was 3 mg/L, the removal rates by carbon layers and sand beds decreased by 17.5% and increased by 9.5%, respectively, compared with a 2 mg/L dosage.

Surface Tension Profiles under Various Microwave Radiation Modes

Surface tension of fluids is crucial for multiphase systems and is often controlled during industrial processes by introducing surfactants. In this study, effect of various microwave radiation modes on surface tension of water was investigated as an alternative physical method to manipulate the surface tension without using chemicals. It is found that surface tension decreased quickly while temperature increased during microwave. Once the radiation was turned off, the temperature returned rapidly as expected. However, surface tension did not recover so much. The minimum surface tension after microwave radiation depended on the power. Moreover, a second radiation can have additional reduction on surface tension.

Systematic Analysis of Carbon Dioxide Activation of Waste Tire by Factorial Design

In this study, waste tire was used as raw material for the production of activated carbons through pyrolysis. ＇Fire char was first produced by carbomzation at 550℃ under nitrogen. A two tactortal design was used to optimize the production of activated carbon from tire char. The effects of several factors controlling the activation process, such as temperature （.830-930℃）, time （2-6h） and percentage ot carbon dioxide （70%-100%） were investigated. The production was described mathematically as a function of these three factors. First order modeling equations were developed for surface area, yield and mesopore volume. It was concluded that the yield, BET surface area and mesopore volume of activated carbon were most sensitive to activation temperature and time while percentage of carbon dioxide in the activation gas was a less significant factor.

Production of Lipase Using Cassava Peel and Sunflower Oil in Solid-State Fermentation： Preliminary Study

Full use of residues from industrial processes is a fundamental necessity of contemporary society, since it avoids impacts to the environment by using residues as inputs for other products of high economic and social importance. In this study, lipase production of the crude enzymatic extracts obtained by Aspergillus niger using cassava peel as substrate and sunflower oil as an inductor was investigated. The optimized cultivation temperature and concentration of inductor were determined using the response surface methodology. The two variables studied exercised influence in the production of lipase in the 95% level of confidence. The response surface obtained indicated that the conditions that maximize lipase activity production were 30.5 ~C and initial concentration of sunflower oil was 2.5% （w/w）. Through this analysis, it is evident that extremes in temperature and concentration of inductor tend to decrease lipase production, since low temperatures decrease metabolism and high temperatures may inactivate the lipase. Optimum lipase yield was 59.8 U/g of dry peel which was fermented for 60 h. Lipase production presents a peak of 61.3 U/g, at 72 h of fermentation. However, this value is statistically equal （p 〉 0.05） of the value of lipase activity obtained for 60 h and 84 h of fermentation.
