Introduction.Coccygodynia is a multidisciplinary disease which is diffi cult to treat. It seriously limits the ability to work and signifi cantly affects the quality of life of patients. The study of somatic dysfunctions in patients with coccygodynia and the analysis of the results of osteopathic treatment of such patients makes it possible to justify the necessity of osteopathic correction of coccygodynia.Goal of the study— to determine the structure of the leading somatic dysfunctions in patients with coccygodynia and to study the effectiveness of osteopathic treatment of this pathology.Materials and methods.The study involved 44 patients from 25 to 65 years old, randomly divided into two groups. The main group of 24 people (20 women and 4 men) received osteopathic treatment, in accordance with the identifi ed leading somatic dysfunctions. Patients of the control group (16 women and 4 men) were treated locally with soft manual techniques (the treatment area was limited by the pelvic region). In order to assess the results of the treatment, we examined the intensity of the pain syndrome and the psycho-emotional state of patients. The severity of the pain syndrome was assessed in accordance with the visual analogue scale (VAS). The psycho-emotional state (with physical and mental components) was assessed with the help of the SF-36 quality of life questionnaire.Results.Somatic dysfunctions typical for patients with coccygodynia have been identifi ed. Osteopathic treatment has proven to be more effective in comparison with local manual therapy of coccygodynia both in early periods and in 3 months after the end of the treatment course.Conclusion.Osteopathic treatment of post-traumatic coccygodynia is effective, and can be recommended for treatment of such patients.

Fixed Bed Reactors

The Paris Metropolitan area, which contains over eight million inhabitants, has a daily output of about 3 M cu.meters of wastewater, the purification of which is achieved by SIAAP (Paris Metropolitan Area Sewage Service) in both Achères and Valenton plants. The carbon pollution is eliminated from over 2 M cu.m/day at Achères. In order to improve the quality of output water, its tertiary nitrification in fixed-bed reactors has been contemplated. The BIOFOR (Degremont) and BIOCARBONE (OTV) processes could be tested in semi-industrial pilot reactors at the CRITER research center of SIAAP. At a reference temperature of 13°C, the removed load is approximately 0.5 kg N NH4/m3.day. From a practical point of view, it may be asserted that in such operating conditions as should be at the Achères plant, one cubic meter of filter can handle the tertiary nitification of one cubic meter of purified water per hour at an effluent temperature of 13°C.

Detection Limits

In Germany the application of procedures such as flocculation and filtration in the preparation of drinking water results in the annual production of an estimated 500,000 t of sediments and sludges. Some of these residues have a potential for being reused, for example in agriculture, forestry, brickworks or waste water treatment. To assess the microbiological quality of residues from waterworks methods for the detection of enterobacteria, Escherichia coli, Salmonella, Pseudomonas aeruginosa, Legionella, poliovirus, Ascaris suis eggs and Cryptosporidium have been evaluated regarding their detection limits and were applied to various residues from German waterworks. Results show that sediments and sludges may contain pathogenic bacteria, viruses and protista. When residues from waterworks are intended to be reused in agriculture or forestry the microbiological quality should therefore be considered.

Community service activities with IbM scheme have been done in home industry of soybean milk processing in Sraten and Kartasura Village, Sukoharjo District. The aim of activities are all partners able process soybean juice into health drink product in ready to drink packaging, adn next can be as new economic commodity to the community. In addition, partners are expected to have a clear administrative and governance system in finance, production and, marketing as an effort to empower communities in Sukoharjo District. Considering the benefits of this soy essence is so great then product diversification is needed so that the product is more acceptable to the market. This program is done through several stages namely 1) Making soybeans into ready-to-drink; 2) Transfer of packing technology; 3) Product marketing and management aspects of soybean processing into beverages in ready-to-drink packaging as well as; and 4) Feasibility analysis of beverage production business made from soybean. Through IbM, training and development of soya bean processing technology is made into an economic commodity product in the form of beverages in ready-to-drink packaging, which can provide new economic alternatives in the community. After this program, the community service activity was conducted with the training and mentoring approach to the two partners, it was able to increase the quantity and quality of soybean beverage production where the yield of production increased almost twice from the original.

to the degree to which it meets the customer’s needs andexpectations. Dissatisfaction with the quality of building projectshas been widely reported in recent times. There are indicationsthat there may be some relationship between the procurementmethod used and customer satisfaction with the delivered product.In particular, traditional competitive bid contracting may havean adverse impact on quality in some circumstances. To shedsome light on reported industry attitudes, a survey of constructionprofessionals in the Sydney metropolitan area was undertaken.The respondents demonstrate mixed views on the effectivenessof the competitive tender system on quality project outcomes. Tosome extent contractors’ attitudes may be determined by theirpreferred current mode of operation. However, some supportis expressed for the contention that quality of outcome can bereduced by an overly cost driven contractor selection process. Inparticular, when economic pressures cause bidders to reduce thetime allocated for the tender process, an inaccurate and unreliablebid may win. This makes it very diffi cult for the reliable contractorto remain profi table. A move to value-based rather than cost-basedprocurement may assist industry performance and customersatisfaction.

Design Phase

Sewage treatment remains a delicate subject and requires technical improvements to increase the efficiency of the systems responsible for the treatment. Numerical simulations are also a very useful tool, especially if they are used during the design phase. Thus, the paper aims to present the results obtained by CFD numerical simulations in the case of an important element within an existing wastewater treatment plant, namely the waste water treatment well, thus obtaining constructive solutions of a better functionally to the designed version. Through these, the work demonstrates the necessity of analyzes with CFD methods during design of the main elements of hydrotechnical constructions, but also the necessity of adjusting the numerical models with results obtained from experiments, measurements. The results show that the modifications described in the paper would bring significant improvements in waste disposal.

The scarcity of water and increasing water pollution are the pressing challenge human being facing. Recovering water and valuable heavy metals is highly desired for treating heavy metal containing wastewater. We proposed a novel hydrate-based process to treat Ni2+ containing wastewater. The water recovery, Ni2+ enrichment factor, desalination efficiency were studied using this cyclopentane hydrate-based method. A water recovery of 43% can be obtained with a desalination efficiency of round 88% and an enrichment factor of 1.6. The desalination efficiency and the quality of the as-made water via the hydrate-based process can be further improved to above 99% via three-stage hydrate reaction. The proposed hydrate-based water treatment process may find wide applications in waste water treatment and heavy metal recycling.
