The results of an investigation for the detection of abs to Mg, Ms and Mm in poultry farms in different regions in Greece are presented. For this purpose during the years of 1997-2000,1449 serum samples were examined, from which 1296 were originated from 72 chicken flocks (27 broiler; 19 layer, 22 breeder and 4 back-yard poultry), 75 from 4 turkey flocks, 58 from 3 flocks of partriges and 20 from 1 ostrich flock. The method used was the R.S.A. test (as a screening test) in combination with HI test. The incidence of Ms for broilers, layers and breeders was over 3 1% of the examined flocks, while the Mg in all the commercial chicken flocks was 17-25%. In back - yard poultry the incidence of Ms was 75% and to Mg 50%. In turkeys and partriges the incidence of Ms was 50% and 66% of the flocks respectively, while the positive flocks for Mg was 25-33%. The turkeys were negative for abs to Mm. The ostrich flock was also negative for abs to Mg and Ms. The results of our investigation indicate that the incidence of mycoplasmas in poultry, especially to Ms, is high in Greece. As a conclusion for the eradication of mycoplasmosis, it is necessary for the poultry industry and for the country, to follow the instruction included in 90/539/EEC directive and to take strickt hygienic measures in order to eliminate the microorganisms from the poultry flocks.

Chicken Patties

Commercial chicken patties contain high fat, which could affect consumers’ health. Jackfruit (Artocarpus heterophyllus) and breadfruit (Artocarpus altilis) may have the potential to be used as the fat replacer in the chicken patties.  This study aimed to evaluate the low-fat chicken patties produced by replacing the fat with jackfruit (JF) or breadfruit (BF) at 0% (control), 50% and 100%. The samples were analysed in terms of water holding capacity (WHC), cooking yield (CY), proximate analysis, colour, texture properties, and sensory parameters. Both BF and JF showed higher value (p<0.05) for WHC, moisture content and protein compared to the control. BF (100%) and JF (100%) were recorded of having significantly reduced fat (p<0.05) at 1.80% and 2.23%, respectively. BF showed higher L*(lightness) and b*(yellowness) values significantly (p<0.05) compared to the control. Not many significant differences (p>0.05) between the control and newly formulated chicken patties texture based on the hardness, cohesiveness, and chewiness recorded, proving that BF and JF did not affect the patties texture. Overall, the sensory evaluation of BF (100%) was preferred by the consumer in terms of appearance, texture, flavour, juiciness, and aroma. Thus, BF (100%) can be considered as the best fat replacer in this study.

The origin of mica polytypes has long been a challenging problem for crystal- lographers, mineralogists and petrologists. From the petrological point of view, interest in this field arose from the potential use of layer stacking data to furnish further informations about equilibrium and/or kinetic conditions prevailing during the crystallization of the widespread mica-bearing rocks. From the compilation of previous experimental works dealing with the occurrence domains of the various mica "polymorphs" (1Mr, 1M, 2M1, 2M2 and 3T) within water-pressure vs temperature fields, it became clear that most of these modifications should be considered as metastable for a fixed mica species. Furthermore, the natural occurrence of long-period (or complex) polytypes could not be accounted for by phase considerations. This highlighted the need of a more detailed kinetic approach of the problem and, in particular, of the role growth mechanisms of basal faces could play in this crystallographic phenomenon.

Potential Use

The properties of metal/semiconductor interfaces have received considerable attention over the past few years, and the Al/GaAs system is of special interest because of its potential use in high-speed logic integrated optics, and microwave applications. For such materials a detailed knowledge of the geometric and electronic structure of the interface is fundamental to an understanding of the electrical properties of the contact. It is well known that the properties of Schottky contacts are established within a few atomic layers of the deposited metal. Therefore surface contamination can play a significant role. A method for fabricating contamination-free interfaces is absolutely necessary for reproducible properties, and molecularbeam epitaxy (MBE) offers such advantages for in-situ metal deposition under UHV conditions

Multiple Regression Technique

Short-form versions of the Screening Test of Spanish Grammar (Toronto, 1973) and the Northwestern Syntax Screening Test (Lee, 1971) were devised for use with bilingual Latino children while preserving the original normative data. Application of a multiple regression technique to data collected on 60 lower social status Latino children (four years and six months to seven years and one month) from Spanish Harlem and Yonkers, New York, yielded a small but powerful set of predictor items from the Spanish and English tests. Clinicians may make rapid and accurate predictions of STSG or NSST total screening scores from administration of substantially shortened versions of the instruments. Case studies of Latino children from Chicago and Miami serve to cross-validate the procedure outside the New York metropolitan area.

Fifty children were administered a screening test for communication disorders under two conditions. Under one condition graduate clinicians administered the test in the traditional pencil and paper format. Under the second condition nonprofessionals administered a computer-managed version of the same test. It was found that the computer-managed screening test yielded satisfactory agreement for the language sections. The results of the articulation section of the screening test were ambiguous.
