Integrated Logistics Support (ILS) applied in the world-class shipbuilding industry has set significant trends in the processes and life cycles of the products and/or systems developed. COTECMAR as a Countrywide pioneer company in this sector, with specific strengths in naval prototypes, has been developing actions together with the National Navy to integrate concepts related to ILS, in its processes. Therefore, a detailed analysis of how these processes are facing the requirements of such support, has become necessary, starting from the initial basis of the possible advantages and opportunities for improvement that this could bring to the corporation and the sector. This is based on the theoretical and conceptual foundations in the ILS framework and how these are developed in the company under analysis.

Abstract Scheelite-bearing albitite is present in the form of rare, highly fractionated felsic dikes in the world-class Zhuxi tungsten deposit. Morphologically, the Zhuxi albitite forms individual dikes with thicknesses from 0.01 to 5.1 m in the orebodies. Additionally, the Zhuxi albitite is characterized by high sodium concentrations (Na2O = 6.08–8.04 wt %), low silicon (SiO2 = 56.81–62.56 wt %) and potassium concentrations (K2O = 1.44–2.62 wt %), and increasing P2O5 (0.1–0.7 wt %), Y (2.72–8.62 ppm), and rare earth element (8.28–28.89 ppm) concentrations from the tops to the bottoms of the dikes, which are controlled by the heterogeneous distribution of apatite grains in the albitite. The trace element geochemical characteristics and Sr-Nd isotope compositions of the albitite and the geochemistry of plagioclase, muscovite, apatite, and scheelite that formed in both the albitite and ore-related (altered) granites strongly suggest a genetic relationship between the two rocks. Given our new data and previous experimental data, as well as natural examples from around the world, we propose that the Zhuxi albitite is the product of a silicate-poor, H2O-rich melt that formed by melt–melt-liquid immiscibility processes in an extremely fractionated residual magma. A deep-seated (>3 kbar) granitic magma reservoir was directly related to the formation of these rare scheelite-bearing albitite dikes. Albitite dikes are the product of extreme fractionation of a granitic magma, and W is highly incompatible during magma evolution regardless of oxygen fugacity; therefore, intense tungsten mineralization development within albitite dikes should serve as an important criterion for judging the tungsten metallogenic potential.

New Framework

In the era of new media, people and societies across the globe are interconnected and extending the new framework to business, trade, and tourism. Different websites and social media are facilitating a plethora of content and information through photos, videos, 3D visualization to satisfy people’s queries, to promote and brand nations. Due to this, tourism is also witnessing a big change. Oman is not far away from this reality. This study aims to gauge into the present tourism status of Oman and its prospects. It will examine the pervasiveness of new media and its increasing significance in holding the desired position in the world-class tourism. Observation and survey methods are applied to reach out the result. Total 125 samples have been collected through an online createdlink from Salalah to understand the mass thinking about new media and its changing role in the tourism sector. The findings provide insight understanding about the current situation of tourism; despite all efforts of Tourism Ministry and increasing penetration of new media, more efforts and awareness are required in terms of the involvement of locals to make Oman international tourism destination.

The City

Since the early 1990s, Kuala Lumpur, the capital city of Malaysia, has been entangled in the modality of World Class City building. Following key insights by critical scholars like Henri Lefebvre and Doreen Massey, in this article the author shows how spatio-temporal processes have historically produced variegated and contested relational spaces in the city centre. In particular, through the case-study of the recent spatial cleansing of the homeless and soup kitchens in downtown Kuala Lumpur, the author argues for not only critically appreciating the durability and mutability of hegemonic relational spaces but also their potential for irruption because of the ethical dynamic of ‘thrown-togetherness’ that these spaces churn up.

This paper describes a new model developed for make-to-order (MTO) sectors namely SHEN Principles, which aims to fill a gap in the world-class manufacturing (WCM) literature that concentrates on the characteristics of the larger traditional make-to-stock (MTS) sector. Using evidence from the literature, especially the MTO literature and the more comprehensive WCM models, a new model was devised. This was then modified in the light of case study evidence collected from the six MTO companies ranging from small-to medium-sized MTO companies. The model presented in this paper known as “SHEN Principle”, will be the current version of the model after all the modifications have been incorporated.
