Design of a system for fastening the pipelines’ elements to be brazed of an automated gas metering unit

The article discusses an automated measuring installation, and also analyzes the subject area. Some types of soldering are considered (capillary, diffusion, contact-reaction and others). The choice of induction brazing for the soldering of pipeline elements of an automated gas metering installation has been substantiated. The work presents the installation of induction heating, considering the required technological parameters. Based on this installation, the basic diagram of the Fitting and the schematic diagram of the connecting sleeve were corrected, which will allow the development of a mobile induction installation as well as collapsible inductors. Potential induction equipment and the developed designs can be used to connect pipelines in the oil and gas industry.

Oral lichenoid contact reaction to amalgam occurring as a leukoplakia-like lesion: a case report

<p class="abstract">This article reports a case of oral lichenoid contact reaction (OLCR) in which a bilateral lesion involving the buccal mucosa was observed. Its relevance lies on that the lesions could be misdiagnosed as an oral leukoplakia, since they showed a typical feature of a homogeneous white plaque; however, fortunately, this misjudgement was spared because one of the lesions, on the right-buccal side, was in direct contact with an amalgam filling. Hence, the suspicion of mucosal contact reaction was made and the patient successfully treated by amalgam replacement. Comments on diagnosing of OLCR is also included is this report.</p>

Multisemiotic interaction: the CEO and stakeholders in Malaysian CEO Statements

Purpose The purpose of this paper is to explore how Malaysian CEO Statements employ language and image to convey interaction between the CEO and stakeholders. Design/methodology/approach The paper examines an archive of 32 Malaysian CEO Statements. The archive is analyzed with Systemic Functional Multimodal Discourse Analysis (SF-MDA), where several interpersonal systems can establish how language and image features articulate interaction. The analysis identifies who the stakeholders are, and how these stakeholders and the CEO interact. Findings There are four stakeholders, who are the community, customer, employee and environment, and these stakeholders are sub-categorized by type or activity. The stakeholders and the CEO share multisemiotic interaction through contact, reaction and equality. These three strategies mimic a face-to-face conversation (contact) and the CEO is depicted to reveal some positive emotions (reaction) to social equals (equality). These strategies reflect synthetic personalization, through which the CEO and stakeholders seem to interact because the CEO speaks directly to stakeholders in friendly conversation about CSR. CEO Statements are part of the quest for social legitimacy and designate corporations as agents of positive social change. Their ideology can be stated as a general principle: corporation A recognizes problem B and proposes solution C, which has positive result D for stakeholder E. Originality/value Previous research has not emphasized interaction in CEO Statements. The paper also utilized SF-MDA, which may enhance the discursive competence or a systematic way to decipher language and image for people who practice or teach corporate communication.

Is genetic involve in the outcomes of contact reactions between parent and offspring and between siblings of the coral Pocillopora damicornis?

Various allogeneic responses have been characterized in stony corals. The responses were thought to be genetically control. However, very little is known about the genetic mechanism of allorecognition in corals. Therefore, the contact reaction between parent-offspring and between siblings of the coral Pocillopora damicornis has been studied. Three types of contact reactions were observed: between young colonies, between adult and young colonies, and between adult colonies. Siblings, which were primary polyps or young colonies derived from the same broodparent, invariably fused. All but one pair of parent-offspring grafts exhibited fusion. However, some pairs of young colonies derived from the same two broodparents showed a different contact response than did the broodparents when their branch tips were paired. When the same pairs of the young colonies were repeated to contact at different age, most pairs yielded the same results. Together with the findings that young colonies were able to recognize their partner less than 1 month after the initial contact, we suggest that contact reaction in coral and time needed for the stable reaction are most probably under genetic control.
