Summary A preliminary study of the bacteriological comparisons of hot processed and normally processed hams was made in cured unsmoked and cured smoked hams. Higher bacterial counts were found in the hot processed hams. Staphylococci were isolated from both hot processed and normally processed hams. Coagulase-positive staphylococci were isolated from one hot processed ham.

Nodular cast irons are an excellent alternative in manufacturing process of axels due to their characteristics and good mechanical properties. However, the necessity of joining the axels to the gears and other components, made in carbon steel, is a great challenge. Traditional fusion welding methods applied to dissimilar ferrous materials are not deeply studied. In this context, it is well known that different materials have distinct melting points which can cause difficulty in welding, besides of defects formation from solidification. Therefore, modern joining processes such as Friction Hydro Pillar Processing (FHPP) are a great alternative. In this technology, a consumable rod is rotated against to a base material, generating the heat due to the friction, promoting materials in the plastic state and then producing the weld. Hence, this work presents a preliminary study of FHPP between the FE55006 nodular cast iron and SAE 8620 steel and evaluates the rod geometry influence on microstructure and surface stresses of the welded joints. Two rod geometries were used and two welds were further produced. The results indicated that an increase in the rod contact area promoted a lower surface stress as well as a better welded joint.

Abstract When talking about dental assistance we actually refer to the prevention, detection and treatment of diseases of the oral and maxillo-facial region which, in most cases, have as a starting point or interest the dento-maxillary system. In this material, we tried to present a comparative study on the typology and complexity of different stages of dental treatments that can be performed in urban areas, compared to various stages of dental treatments that are performed and / or could be made in rural dental offices from in Romania.

Abstract An end point color standard based on reflectance, which can be described by the Munsell system of color notation, was developed for the modified resazurin test used to estimate bacterial counts in maple sap. In order to secure a reflected color, a sterile, nonfat milk solution was added to the clear sap-dye test solution to render it opaque. Results of tests made in accordance with this method are presented in graphic form.

Dental malocclusion is present in all societies but its prevalence varies. There is a need to identify the occlusal problems, their incidence and the need for treatment so that appropriate manpower arrangements may be made. In this initial survey, patients attending the orthodontic clinic at the Riyadh Armed Forces Hospital were examined for occlusal relationship, crowding, and facial type. There are indications amongst Saudi Arabian patients of a tendency for bimaxillary proclination and a greater proportion of Class III malocclusion, than in Western communities. The need for a comprehensive survey is identified.

SummaryThe microflora of ten batches of La Serena cheese, made from raw milk of Merino ewes and using vegetable rennet as coagulant, was monitored throughout a 60 d ripening period. After 15 d, lactic acid bacteria predominated in the interior of the cheese, whilst lactic acid bacteria and lactic acid-utilizing species of yeasts and moulds predominated on the cheese surface. Coagulase-positive staphylococci were not detected in the interior or on the surface of any of the cheeses after 45 d and faecal coliforms were not found after 60 d. Higher death rates of staphylococci and coliforms were recorded for cheese made in spring than for the cheese made in winter.

The current Section VIII Division 2 of ASME code does not permit method A of paragraph 5.5.2.3 to be used for the exemption from fatigue analysis when the design allowable stress is taken in the time dependent temperature range. Method B of paragraph 5.5.2.4 also cannot be used because it requires the use of the fatigue curve which is limited to 371 ° C and below the needed temperature. Code Case 2605 is a rule for fatigue evaluation of 2.25Cr-1Mo-0.25V steels at temperatures greater than 371 ° C and less than 454 ° C. An inelastic analysis including the effect of creep shall be performed for all pressure parts according to Code Case 2605. Especially, a full inelastic analysis shall be performed using the actual time-dependent thermal and mechanical loading histograms for the lateral nozzle based on preliminary study. It takes much time to perform this inelastic analysis for all full histograms and obtain the fatigue evaluation results when large number of cycles of full pressure is specified in user’s design specification. This paper provides sample analysis results for nozzles and clarifies issue of implementation of Code Case 2605. Then, the proposal of simplification and modification of Code Case 2605 from these results are proposed.

The biofilms of the wooden tables used for the acidification of the curd were investigated for PDO Provola dei Nebrodi cheese, a traditional stretched cheese made in eastern Sicily (southern Italy) from raw cows’ milk. To this purpose the wooden tables of four dairy facilities were analysed for their microbiota by scanning electron microscopy (SEM) analysis and a combined culture-independent and -dependent microbiological approach. SEM inspection showed an almost continuous biofilm formation. MiSeq Illumina analysis identified 8 phyla, 16 classes, 25 orders, 47 families and 50 genera. Corynebacterium, Bifidobacterium and lactic acid bacteria (LAB) were detected in all samples. In particular, the LAB genera detected on all wooden tables were Lactobacillus, Streptococcus and Lactococcus. LAB dominated the surfaces of all wooden tables with levels higher than 7.0 Log CFU/cm2. In particular, the LAB found at the highest levels were mesophilic cocci. Coagulase positive staphylococci, Salmonella spp., Listeria monocytogenes and Shiga-toxigenic Escherichia coli were never detected. Twenty-seven dominating LAB strains were identified within the genera Enterococcus, Lactobacillus, Lacticaseibacillus, Lactiplantibacillus, Levilactobacillus, Lactococcus, Leuconostoc, Pediococcus and Streptococcus. This work showed that the wooden table used during the production of PDO Provola dei Nebrodi cheese is a safe system and a microbiologically active tool.

Setting up an eye tracking experiment involves multitier processes that cover important issues such as developing the data collection guidelines, establishing data analysis protocols, and giving meaning to data. Although eye tracking handbooks have established imperative discussion on how the data should be analysed and written, there is still a dearth in the literature on data collection guidelines caused by the variety of features in different kinds of eye trackers. In this study, the researchers review the use of a wearable eye tracking apparatus with authentic materials and interview protocols. Exemplified through a preliminary study conducted on Year Six students in a primary school that investigates the internal processes of reading ESL texts, the significance and implications of using a wearable eye-tracking apparatus with a single point calibration are reported to improve the data collection guidelines. Relatedly, considerations for research procedures and instrument designs are also made in this paper.

This work provides a preliminary study of finite element model updating in bladed disk-shaft assemblies. The use of finite element method has been widely found and accepted in engineering analysis. However, the limitations of numerical modeling, in this case finite element model, cannot be avoided. The approach of numerical modeling is limited by the assumptions made in the development such as insufficient information on material, geometry etc. Hence, model updating is required to improve the modeling results. Since model updating involves experimental results, the measurement limitations also affect the accuracy of updated model. In this paper, a model updating technique is applied to study mistuned bladed disks. Important parameters for model updating are discussed and the updating process is carried out on an industrial radial blisk. By using the model updating technique, the model of mistuned bladed disk can be enhanced.
