Background: Development of science and technology led to people having birth defects (congenital), trauma or because of there sected tumor can be made of a prosthesis. Purpose: To learn the technique of making obturator with magnet attachment. Review: Assembly of magnet in obturator can improve the stability and retention of the prosthesis. Conclusion: The techniques of making obturator with magnetic attachment begins with making the double impression. The part defect is waxed on a master cast, and the contoured wax lid was fabricated on the master cast to close the hollow obturator. The lid along with the magnetic assembly was attached to the obturator with auto polymerizing resin. Obturator is inserted in the patient and created a master cast for the fabrication of denture. Wax of master cast of denture is assembled magnet for attachment to the obturator, then flasking, wax boil-out of master cast, acrylic processing, deflasking, finishing, and polishing.

Corporate Criminal Liability

The development of science and technology and globalization were already unstoppable today, not only have a beneficial impact, but also often have a negative impact for example by the "globalization of crime" and the development of quality (modus of operation) and the quantity of criminal acts. Offenses rife nowadays with regard to the corporate existence of the corporation is a criminal offense that could result in serious and widespread impact, damage the joints of the nation and threatens the stability of the State. Therefore, the law should take back its role in order to create justice and welfare and in handling needed ways remarkable that one of them is to make the corporation as a subject of criminal law that is considered to be committing a crime and can be criminally).

The corrosion and electrochemical properties of sputter-deposited nanocrystalline binary W-Mo alloys were studied after immersion for 2429 h in different concentrations of NaOH solutions open to air at 25°C using corrosion tests and open circuit potential measurements. Molybdenum acts synergistically with tungsten in enhancing the corrosion resistance of the sputter-deposited binary W-Mo alloys so as to show higher corrosion resistance than those of alloy-constituting elements (i.e. tungsten and molybdenum) after immersion for 24 h in NaOH solutions. Open circuit potentials of all the examined sputter-deposited W-Mo alloys are shifted to the more positive (noble) direction with increasing molybdenum content in the alloys. The stability of the spontaneously passivated films formed on the binary W-Mo alloys is decreased with increasing concentrations of NaOH solutions. In spite of these facts, the corrosion rates of all the examined W-Mo alloys are almost independent of concentrations of NaOH solutions after immersion for 24 h at 25°C.Key words: nanocrystalline W-Mo alloys; sputter deposition; corrosion resistance; open circuit potential; NaOH solutions DOI: 10.3126/njst.v11i0.4137Nepal Journal of Science and Technology 11 (2010) 147-152

This article explores contemporary debates about the competence of juries to assess scientific and technical evidence. Most existing approaches measure jury competence against an unproblematized yardstick of `the correct scientific understanding'. We will develop an alternative, more sociologically and epistemologically nuanced view of the jury comprehension of science which significantly reframes these issues for both proponents and opponents of the jury. In particular, by using examples surrounding the recent US litigation involving birth defects allegedly caused by use of the drug Bendectin, we will challenge the common claim that inconsistencies in jury findings provide support for restricting the role of the jury in matters involving science and technology based on alleged jury `incompetence'. We conclude by noting that jury competence is a politically charged ascription.

The stability to storage at −20°C of 29 enzymes of rat tissues was measured for periods of up to 100 days. The enzymes could be divided into four groups: (1) those that increased in activity with storage; (2) those that showed transient rises subsequently declining to the original activity or below; (3) those that showed no significant change; (4) those that declined in activity. Details of methods used and of results obtained have been deposited as Supplementary Publication SUP 50038 (19 pages) at the British Library (Lending Division) (formerly the National Lending Library for Science and Technology), Boston Spa, Yorks.

Background:  Magnetic attachment can be used as  a retentive devices in overdenture technique in prostheses. The magnets are attached with remaining root structure transfer the occlusal load to the bone through the periodontal ligament of retained roots and then prevent resorption of the  alveolar ridge. Alvelar ridge plays an important role for the retention and stability of the denture as they will support the denture base. Magnetic assembly consist of magnet and coping with a keeper on the remaining tooth structure  since magnetic attachment can provide support, stability and retention. Purpose: The purpose of this case report was to report magnetic attachment retained complete overdenture design and fabrication as a preserve to alveolar bone height to achieve retention and stability of the denture.  Case: A 69 years old female patient, a baker and private English teacher with partial edentulous ridge came to Dental Hospital of Airlangga University asked for dentures. Clinical examination shown a complete edentulous in the upper jaw and partial edentulous in the lower jaw. The remaining teeth were 33, 34, 35, 43 and 44. 33 and 35 are chronic gangrene radix, 35 shown a slightly mobility. 34 non vital, 44 and 45 are vital with moderate resorption. Case management : All the left teeth in the lower jaw were consulted for endodontic treatment. Magnetic attachment retained complete overdenture was choosen for the lower jaw and complete denture for the upper jaw. The remaining teeth in the lower jaw kept the alveolar ridge from resorption and the magnet provided extra retention for the complete overdenture. Discussion: Overdentures supported by magnet attachment achieved greater satisfaction, gives better retention  and stability for the denture. On the other side, the natural abutment teeth in overdentures  preserved  better proprioception and psychologically beneficial as the patient had not undergone extraction. As a conclusion, overdenture supported by magnetic attachment can be used to increase support, retention and stability especially in the lower jaw and also  prevent further alveolar ridge resorption. Conclusion: Overdenture supported by magnetic attachment can be used to increase retention and the residual root also prevent further alveolar ridge resorption.

Conti: One of the main conclusions of the Wolf-Rayet symposium in Buenos Aires was that Wolf-Rayet stars are evolutionary products of massive objects. Some questions:–Do hot helium-rich stars, that are not Wolf-Rayet stars, exist?–What about the stability of helium rich stars of large mass? We know a helium rich star of ∼40 MO. Has the stability something to do with the wind?–Ring nebulae and bubbles : this seems to be a much more common phenomenon than we thought of some years age.–What is the origin of the subtypes? This is important to find a possible matching of scenarios to subtypes.

Luminescent Spectrum

Work has recently begun in the Physics Department of the Manchester College of Science and Technology on an attempt to simulate lunar luminescence in the laboratory. This programme is running parallel with that of our colleagues in the Manchester University Astronomy Department, who are making observations of the luminescent spectrum of the Moon itself. Our instruments are as yet only partly completed, but we will describe briefly what they are to consist of, in the hope that we may benefit from the comments of others in the same field, and arrange to co-ordinate our work with theirs.
