Abstract: the spatial and temporal retention of metals has been studied in water and sediments of the gavi?o river, anagé and tremedal reservoirs, located in the semi-arid region, bahia - brazil, in order to identify trends in the fluxes of metals from the sediments to the water column. the determination of metals was made by icp oes and et aas. the application of statistical methods showed that this aquatic system presents suitable conditions to move cd2+ and pb2+ from the water column to the sediment.
Battle against Aging and Folds: Benefit and Risks of the Semi-Permanent Fillers Polylactic Acid and Calcium Hydroxylapatite  [PDF]
Elisabeth Hanf, Ursula Gresser
Advances in Aging Research (AAR) , 2014, DOI: 10.4236/aar.2014.32021
Abstract:

Background: Semi-permanent fillers are among the most favorable fillers on the market. Through their unique mode of action and its associated lasting aesthetic effect, they take an exceptional position. Objective: To compare the two semi-permanent fillers Poly-L-Lactic Acid (PLLA) and calcium hydroxylapatite (CaHA) in reference to the aesthetic result, patient satisfaction and side effects. Methods: Studies on side effects, patient satisfaction and aesthetic results after augmentation with semi-permanent fillers were analyzed. Results: Semi-permanent fillers seem excellently suited for the augmentation of very deep wrinkles particularly in the lower half of the face. In general, high patient satisfaction can be determined with both fillers. Here, the effect from the polylactic acid can be verified for up to two years while no effect could be verified already after one year in a majority of the patients augmented with CaHA. Short-term side effects such as bleedings or erythema in the region of the augmented area have been observed in both fillers during augmentation. The incidence of nodules and granulomas seems significantly higher in augmentations with PLLA compared to CaHA. Rare side effects such as an embolization of a blood vessel caused by the implant have been described for both fillers in case reports. Conclusion: Semi-permanent fillers are superbly suited for wrinkle augmentation. Which filler is the preferred one in what case depends strongly on the individual needs of the patient and the therapist’s experience.

An Assessment of Pension Insurance on the Socio-Economic Life of the Retired Population in Buea-Cameroon  [PDF]

Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.44028
Abstract: This work aimed at evaluating the impact of pension insurance on the socio-economic life of the retired population in Buea-Cameroon. The objectives of the study were to appraise the policies and procedures used to obtain old age pension and old age allowance, and to assess the impact of old age pension and old age allowance on the socio-economic life of the retired population in Cameroon, precisely the Buea municipality. To achieve these objectives, the researcher came out with methods of data collection which included questionnaires that were administered to respondents in Buea and interviews. The said data were analysed with the help of simple regression and it was discovered from the analyses that an increase in old age pension and old age allowance will better off the socio-economic life of the retired population. Moreover, this relationship also portrays that, a fall in old age pension and old age allowance will worsen off the socio-economic life of the retired population. From these findings, the researcher recommends that, the National Social Security Fund should be able to hold seminars and give advices to the retired population on how they could better manage their retirement income, which will enable them to meet up their standard of living and satisfy their basic necessities such as their health, children’s education, feeding and many others.
The History, the Memory and the Educational Institution: A Necessary Relationship  [PDF]

Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.79140
Abstract: This paper discusses the relationship between history, memory and the institution of the school. It builds on what the process of searching for, analyzing and interpreting sources according to a theoretical framework reveals about the way the institution of the elementary school came into being in the province of Paraná (1854-1889). Such reflections resulted from dealing with official documents, reports and letters of the public teaching (Presidents of the Province, General Inspectors of Public teaching and teachers who worked in schools) preserved in the Public Archives of Paraná. For in depth analysis we used Le Goff, Saviani, Magalhaes, Farge, Bloch, Thompson and Ciavatta. The reflections proceed from the position that teachers demonstrated originated by the schools. It is concluded that although the data presented by the people in charge at the end of the provincial period showed the failure of the school education, in fact, the work of the teachers has contributed to the process of the institution of the elementary school in the Province.
How Can Manual Rotation Reduce Vacuum, Forceps and Caesarean Deliveries?—A Review of the Evidence  [PDF]
Cathrine Os, Elisabeth Severinsson
Open Journal of Nursing (OJN) , 2017, DOI: 10.4236/ojn.2017.71007
Abstract: The aim of this review was to investigate whether manual rotation can be used to reduce vacuum, forceps and caesarean deliveries in women with occiput posterior or occiput transverse positions from 7 cm dilation in labour. A search strategy was developed and relevant papers published between 1946 and January 2015 were identified from electronic databases. Key search terms used were manual and digital rotation, labour presentation, obstetric labour complications, occiput posterior and version foetal. The search revealed 330 papers. A short list of 33 publications of possible relevance was compiled and assessed using the following criteria: primary studies on the effectiveness of manual rotation performed in women with singleton occiput posterior or occiput transverse presentations published in English or the Scandinavian languages. The quality of the included studies was evaluated by means of the critical appraisal tools for quantitative studies. Seven studies were included in the thematic analysis. The results varied but the main finding was that in order to decrease vacuum, forceps and caesarean deliveries by means of manual rotation, it is essential that the procedure is successful. The success rate of manual rotation is dependent on the experience of the healthcare professionals who perform the rotation procedure rather than the technique employed. Predictors of successful manual rotation were used after engagement of the foetal head, at full dilatation and prophylactic use before failure to progress in labour. In conclusion, although the results vary, there is a consensus in all the studies that manual rotation is worth considering and that it can contribute to decreasing vacuum, forceps and caesarean deliveries. The implications for practice are that successful manual rotation can reduce caesarean delivery and increase spontaneous vaginal delivery, but experience is necessary to perform successful rotations. Because there are no risk factors associated with manual or digital rotation when performed after engagement of the head and at full dilatation, they are worth considering. The central role of the midwife in each individual labour makes her important for ensuring that manual rotation can be considered at the right time in labour.

Abstract: (germinability after desiccation, storage and cryopreservation of seeds from endemic encholirium mart. ex schult. & schult. f. and dyckia schult. & schult. f. species (bromeliaceae)). seed storage procedures require previous determination of optimal temperature and light conditions for germination, as well as of tolerance to desiccation and low temperatures. the aim of this paper was to study the effects of desiccation, storage at low temperatures and cryopreservation on the germinability of seeds of six encholirium and two dyckia species, which were selected according to vulnerability criteria. initial germinability of newly harvested seeds varied from 35 to 95%. seeds presented photoblastic behaviour since light was necessary to induce or increase germination. except for e. heloisae and e. scrutor, desiccation did not affect significantly the germinability of tested seeds. storage for one year at 4 and -20 oc did not affect the germinability of desiccated seeds, except for e. pedicellatum. germinability after freezing in liquid nitrogen was higher than or similar to control seeds for all species. however, freezing tolerance of e. pedicellatum seeds was only achieved after desiccation to 2.5% moisture content. as regards tolerance to desiccation and to storage at low temperatures, the seeds studied here can be classified as orthodox and conserved ex situ.

Abstract: the present study aims to quantify basic parameters for the transport and retention of metal ions in contention barrier systems. a synthetic leachate with ph 1 and known concentrations of ions chromium, cadmium and copper was used. sorption and molecular diffusion experiments were carried out in compacted soil, soil mixture with 10% sodium bentonite and compacted soil overlaid with geomembrane. it was implemented in the program mphmtp (multi phase heat and mass transfer program) where the equations describe ion behavior under adjusted parameters obtained from sorption and diffusion tests. the geomembrane’s presence minimizes ion migration through a diffusive process, and eliminates the need for the soil sorption capacity. but the soil with the bentonite option proved to be the most predominant specific alternative due to its cadmium sorption capacity.
