Many steel parts are electro-plated with chromium to protect them against corrosion and to improve their wear-resistance. Good adhesion of the chrome plate to the steel surface, which is essential for long term durability of the part, is extremely dependent on surface preparation prior to plating. Recently, McDonnell Douglas developed a new pre-treatment method for chrome plating in which the steel is anodically etched in a sulfuric acid and hydrofluoric acid solution. On carbon steel surfaces, this anodic pre-treatment produces a dark, loosely adhering material that is commonly called the “smut” layer. On stainless steels and nickel alloys, the surface is only darkened by the anodic pre-treatment and little residue is produced. Anodic pre-treatment prior to hard chrome plating results in much better adherence to both carbon and alloy steels.We have characterized the anodic pre-treated steel surface and the resulting “smut” layer using various techniques including electron spectroscopy for chemical analysis (ESCA) on bulk samples and transmission electron microscopy (TEM) and electron energy-loss spectroscopy (EELS) on stripped films.

Long Term Follow Up

Studies have investigated the applications of Continuous Positive Airway Pressure (CPAP) therapy in the treatment of hypernasality due to velopharyngeal dysfunction (VPD; Cahill et al., 2004; Kuehn, 1991; Kuehn, Moon, & Folkins, 1993; Kuehn et al., 2002). The purpose of this study was to examine the effectiveness of CPAP therapy to reduce hypernasality in a female subject, post-traumatic brain injury (TBI) and pharyngeal flap, who presented with signs of VPD including persistent hypernasality. Improvements in mean velopharyngeal orifice size, subjective perception of hypernasality, and overall intelligibility were observed from the baseline to 8-week post-treatment assessment intervals. Additional long-term assessments completed at 2, 3, and 4 months post-treatment indicated decreases in immediate post-treatment improvements. Results from the present study suggest that CPAP is a safe, non-invasive, and relatively conservative treatment method for reduction of hypernasality in selected patients with TBI. More stringent long-term follow up may indicate the need for repeated CPAP treatment to maintain results.

Background: Sticker sarcoma, also called venereal sarcoma or venereal lymphosarcomatosis, is a tumor of the external genital organs in females and males. In male animals the penis and foreskin (prepuce) are affected, in the female, it happens in vagina (vagina) and labia (vulva). The diagnosis of sticker sarcoma is based on the chronic discharge, the typical locations and the characteristic appearance of the tumor. Methods: We have relied on the treatment method on the complete surgical removal of all cancer cells that we can access. Results: After surgery, we notice recurrent tumors about six months after surgical treatment, indicating the need for other treatments in addition to surgery. Conclusion: Although spontaneous regressions of sticker sarcoma are documented (with permanent immunity), chemotherapy is the treatment of choice today. Irradiation should also be effective. If the tumor is only removed surgically, there is a high rate of recurrence, and this is what happened with the case that we treated, as the tumor reappeared after less than six months.

ABSTRACTChildren with Special Needs are children who have special behaviors that require guidance and special education from his parents and teachers. Like children in general, children with special needs also have the development and growth of the physical, mental, psychological and sexual. Based on the research conducted by researchers together with some teachers in individuals investigated, if the children with special needs get therapy sustained every day about sexual behavior and patterns of life, then they tend to have a positive sexual behavior, but if the therapy is not done, then they tend to a negative behavior. This study used the name Parents Therapy, in which the children with special needs who have negative sex in schools (respondents one child), as is often held his cock, embraced by aggressive children of the opposite sex therapy is given not only to their children but also their parents through counseling services. This treatment method is given for 30 days, but there are three days of therapy which is not performed as comparison changes in deviant behavior in children. The results of this therapy are very positive and significant, in which the child has calmness in his mental condition and the negative sexual behavior decreased (changed in his behavior).Keywords: Children with Special Needs, sexual behavior, Parents Therapy and counseling servicesABSTRAKAnak Berkebutuhan Khusus adalah anak yang memiliki perilaku khusus yang memerlukan bimbingan dan pendidikan khusus dari orangtua maupun guru. Seperti layaknya anak pada umumnya, Anak Berkebutuhan Khusus juga memiliki perkembangan dan pertumbuhan dari sisi fisik, mental, kejiwaan maupun seks. Dari penelitian yang dilakukan oleh peneliti bersama dengan beberapa guru pada individu yang diteliti, apabila anak berkebutuhan khusus mendapatkan terapi yang berkesinambungan setiap harinya tentang perilaku seks dan pola hidup, maka anak memiliki perilaku seks yang positif, namun apabila terapi tidak dilakukan, maka anak memiliki perilaku yang negatif. Penelitian ini menggunakan nama Parents Therapy, di mana, anak berkebutuhan khusus yang mengalami perilaku seks negatif di sekolah (responden satu anak), seperti sering memegang kemaluannya, memeluk dengan agresif anak-anak yang berlawanan jenis diberikan terapi bukan hanya pada anaknya namun juga orangtuanya melalui layanan konseling. Metode terapi ini diberikan selama 30 hari, namun ada tiga hari terapi tidak dilakukan sebagai pembanding perubahan perilaku menyimpang pada anak. Hasil terapi ini sangat positif dan signifikan, di mana anak tersebut memiliki ketenangan dalam kondisi jiwanya dan perilaku seks negatifnya mengalami penurunan (ada perubahan perilaku).Kata kunci: Anak Berkebutuhan Khusus, perilaku seks, Parents Therapy, dan layanan konseling

Distillery Spent Wash

The paper deals with the waste disposal problem of the alcohol industry caused by the widespread use of alcohol as biofuels. In the technology for the production of alcohol from cereal crops, a distillery spent wash (DSW) is formed (per 1 dm3 of alcohol – 10–20 dm3 DSW), which refers to highly concentrated wastewater, the COD value reaches 40 g O2/dm3. Since the existing physical and chemical methods of its processing are not cost-effective, the researchers develop the processing technologies for its utilization, for example, an anaerobic digestion. Apart from the purification of highly concentrated wastewater, the advantage of this method is the production of biogas and highquality fertilizer. The problems of biotechnology for biogas production from the distillery spent wash are its high acidity–pH 3.7–5.0 (the optimum pH value for the methanogenesis process is 6.8–7.4) and low nitrogen content, the lack of which inhibits the development of the association of microorganisms. In order to solve these problems, additional raw materials of various origins (chemical compounds, spent anaerobic sludge, waste from livestock farms, etc.) are used. The purpose of this work is to determine the appropriate ratio of the fermentable mixture components: cosubstrate, distillery spent wash and wastewater of the plant for co-fermentation to produce an energy carrier (biogas) and effective wastewater treatment of the distillery. In order to ensure the optimal pH for methanogenesis, poultry manure has been used as a co-substrate. The co-fermentation process of DSW with manure has been carried out at dry matter ratios of 1:1, 1:3, 1:5, 1:7 respectively. It is found that when the concentration of manure in the mixture is insufficient (DSW/manure – 1:1, 1:3), the pH value decreases during fermentation which negatively affects methane formation; when the concentration of manure in the mixture is increased (DSW/manure – 1:5, 1:7), the process is characterized by a high yield of biogas and methane content. The maximum output of biogas with a methane concentration of 70 ± 2% is observed at the ratio of components on a dry matter “wastewater: DSW: manure” – 0,2:1:7 respectively. The COD reduction reaches a 70% when using co-fermentation with the combination of components “wastewater: DSW: manure” (0,3:1:5) respectively.
