Focusing on some issues which divided into few micro subs such as communicative situation, communicative event and communicative act in Seba Baduy ceremony, Lebak Banten Region. The Applied method for the project is qualitative method of communication Ethnographic. The subject of the research is  Baduy and Jaro Luar community which follows Seba Baduy ceremony, there are 3 informants obtained by purposive technique in the researched ceremony. The data gathering requirement held through in-depth interview, non-participant observation, field notes, literature study, documentations and daring searching.  The technique of testing the validity of data by increasing the persistence of observation, triangulation and discussion among friends. For the analytical data used are descriptive, analytical, and interpretation. Research result shows that communicative situation found in the Seba Baduy ceremony which held on two spots Pendopo of Lebak Region and Pendopo of Banten Province on Safar month. Communicative event in the Seba Baduy ceremony as the gratitude and do what the ancestors of Baduy community have passed through generations. While communicative acts in Seba Baduy is act which shows verbal and non-verbal acts as respect expression for the Government and appreciate the nature.

Compliance with new regulations in old plants remains a recurring challenge because of negative outcome of incidents. This challenge stems from uncertainties in the facilities’ integrity, owing to inadequacy of existing integrity-validating technologies. Process facilities deteriorate through cyclic operations, while encroachments from expanding population characteristically raise the risk-levels, leading to need for higher grade materials to meet operational expansions. Retroactive compliance becomes a nightmare with every new regulation without a robust cost-to-benefit assurance. This paper discusses two-phased qualitative and quantitative risk modelling approach through systematic field-data-gathering, hazards identification and analysis by a twelve-man risk management engineers. The methodology successfully computed a “health-check" of the facility’s compliance to new regulations, 17 high-risk-hazards were extracted from 42 potential hazards and successfully established varied individual risk levels ranging from 4.07E-06 to 1.64E-04/year. Also, risks ranged from 1.00E-04 to 5.00E-05/year of tolerable risks to the environment, society, and business were recorded across the facility while, 22 risk-mitigation actions were recommended.

Risk Based Inspection (RBI) results in calculating a risk value for each piece of plant fixed-equipment. Usually RBI implementation results in fixed-equipment inspection program modification. Inspection is specified for equipment items that exceed Owner acceptable risk criteria while it is waived for equipment that is below acceptable risk levels. In RBI analysis, equipment risk value consists of a Likelihood-of-Failure (LOF) and a Consequence-of-Failure (COF) element. Furthermore LOF value is the sum of different equipment damage mechanisms (internal corrosion, external corrosion and cracking mechanisms). This paper describes on Olefins plant gains from applying RBI as a reliability-engineering tool instead of an inspection optimization tool. Based on RBI calculated risk values, fixed-equipment relative risk ranking is established to: • set priorities and focus our attention on the critical areas; • justify capital investment for Lifetime Extension projects; • proactively address Loss of Primary Containment and Process safety issues.

Background: Considering the reported positive effects of risk management practices and monitoring them by conducting risk assessments and achieving safety improvements, this study was conducted to assess the risks in the educational laboratories of Qom University of Medical Sciences. Methods: This cross-sectional study was conducted in 13 medical and paramedical educational laboratories. To assess safety conditions in the laboratories, a comprehensive safety checklist was developed, and in order to assess the risks of laboratories, a method called FMEA was used. Two trained occupational health and safety experts evaluated the laboratories understudy, identified the hazards, completed the relevant checklists, and subsequently ranked them based on severity, occurrence, and detection. Finally, a comparison was made based on the calculated Risk Priority Number (RPN) for each hazard. Results: In general, the fire hazards and electrical hazards of 54% of the laboratories have been accompanied by normal risk (RPN< 70), and nearly 8% of the laboratories had critical fire and electrical risks, including chemistry and immunology laboratories. In the case of equipment hazards, nearly 60% of the laboratories had critical or semi-critical risk levels. It is indicated that health exposure hazards were the most important hazards compared to the other ones. So that 61.5% of the laboratories had critical risk, and 15.3 % of them categorized as semi-critical risk. The highest RPN allocated to the biochemistry and chemistry laboratories (RPN>250). Conclusion: The results of this study showed that in general, three types of hazards, including health hazards, equipment, and material storage, should be given priority.

Quantitative risk analysis was carried out on a proposed natural gas pipeline based on preliminary data using the methods and models implemented in the PIRAMID™ software program. The high-risk areas were identified and the main causes of risk were analyzed. Measures to lower the calculated risk levels were developed, which will be taken into consideration in the design and construction of the pipeline.

Si3n4 Ceramics

Whisker and fiber reinforcement has been established as an effective toughening concept for monolithic structural ceramics to overcome limited fracture toughness and brittleness. SiC whiskers in particular combine both high strength and elastic moduli with good thermal stability and are compatible with most oxide and nonoxide matrices. As the major toughening mechanisms - crack branching, deflection and bridging - in SiC whiskenreinforced Al2O3 and Si3N41 are critically dependent on interface properties, a detailed TEM investigation was conducted on whisker/matrix interfaces in these all-ceramic- composites.In this study we present HREM images obtained at 400 kV from β-SiC/α-Al2O3 and β-SiC/β-Si3N4 interfaces, as well as preliminary analytical data. The Al2O3- base composite was hotpressed at 1830 °C/60 MPa in vacuum and the Si3N4-base material at 1725 °C/30 MPa in argon atmosphere, respectively, adding a total of 6 vt.% (Y2O3 + Al2O3) to the latter to promote densification.

In recent years, in the Russian Federation there has been an increase in the levels of radiofrequency electromagnetic fields in residential areas, including due to an increase in the number of base stations (BS). The purpose of sanitary and epidemiological surveillance at the stages of placement and commissioning of base stations (BS) is to prevent their adverse effects on public health. The increase in the number of base stations, together with the advent of new electronic equipment and antennas, provide opportunities for improving the processes of their accounting at the stage of placement and monitoring of the levels of radiofrequency electromagnetic fields at the operation stage. This automation tool can be a geo-information portal for providing sanitary and epidemiological surveillance of cellular base stations. The prototype of the geo-information portal allows both calculating the size of sanitary protection zones (SPZ) and building restriction zones (RZ) from the BS in online mode, displaying the results of calculations in graphical form and issuing sanitary and epidemiological conclusions for the placement and operation of base stations. The geo-information portal has the ability to synchronize with the data of the radio frequency center. Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing will be able to receive up-to-date analytical data. There will be completely automated processes of collecting, processing and storing information on BS.
