THE STRATEGIC CHOICES IN ACHIEVING TOURISM'S COMPETITIVENESS AND PERFORMANCE AMONG HOTELS IN INDONESIA

The current debate between external strategy and a resource-based approach as a driver of competitiveness is rarely investigated in a developing region. This study investigates whether an external focus or a resource-based strategy is better for leveraging the hotel industry's competitiveness and performance in a developing area in Indonesia. The authors obtained saturated responses from 204 managers and analyzed them with PLS-SEM's two-stage and repeated indicator approach while interviewing some of them. This study developed a formative model in PLS-SEM as a better method for investigating an organization's performance than a reflective approach. Quantitative analysis revealed the resource-based view as a better basis for supporting hotels' competitiveness and performance; however, the interview revealed considerable concerns over arising externalities. This paper suggests that hotel managers improve their internal core competence instead of wasting resources and worrying about external issues.

Study on the Perspective of Mechanical Properties and Corrosion Behaviour of Stainless Steel, Plain and TMT Rebars

In the present research, the effects of various alloying elements and microstructural constituents on the mechanical properties and corrosion behaviour have been studied for four different rebars. The microstructures of stainless steel and plain rebar primarily reveal equiaxed ferrite grains and ferrite-pearlite microstructures, respectively, with no evidence of transition zone, whereas tempered martensite at the outer rim, followed by a narrow bainitic transition zone with an internal core of ferrite-pearlite, has been observed for the thermomechanically treated (TMT) rebars. The hardness profiles obtained from this study display maximum hardness at the periphery, which decreases gradually towards the centre, thereby providing the classical U-shaped hardness profile for TMT rebars. The tensile test results confirm that stainless steel rebar exhibits the highest combination of strength (≈755 MPa) and ductility (≈27%). It has been witnessed that in Tafel plots, the corrosion rate increases for all the experimental rebars in 1% HCl solution, which is well expected because the acid solutions generally possess a higher corrosive environment than seawater (3.5% NaCl) due to their acidic nature and lower pH values. However, all the experimental results obtained from Tafel and Nyquist plots correlate well for both 1% HCl and 3.5% NaCl solutions.

Preparation of Multicore Colloidosomes: Nanoparticle-Assembled Capsules with Adjustable Size, Internal Structure, and Functionalities for Oil Encapsulation

Colloidosomes, also known as Pickering emulsion capsules, have attracted attention for encapsulation of hydrophilic and hydrophobic actives. However, current preparation methods are limited to single core structures and require the use of modified/engineered nanoparticles for forming the shell. Here, we report a fast, simple, and versatile method for producing multi-oil core silica colloidosomes via salt-driven assembly of purely hydrophilic commercial nanoparticles dispersed within an Oil-In-Water-In-Oil (O/W/O) double emulsion template. The internal structure and overall diameter of the capsules can be adjusted by altering the primary and secondary emulsification conditions. With this approach, 7 to 35 µm diameter multicore colloidosomes containing 0.9 to 4.2 µm large oil cores were produced. The capsules can easily be functionalized depending on the type of nanoparticles used in the preparation process. Here, metal oxide nanoparticles, such as Fe3O4, TiO2 and ZnO, were successfully incorporated within the structure, conferring specific functional properties (i.e. magnetism, photocatalysis) to the final microcapsules. These capsules can also be ruptured using ultrasound, enabling easy access to the internal core environments. Therefore, we believe this work offers a promising approach for producing multicore colloidosomes with adjustable structure and functionalities for the encapsulation of hydrophobic actives.

A prelude to wearable technology for the measurement and restoration of core body temperature and heart rate in athletes suffering from hypothermia

An individual who is in good physical health tends to exhibit an internal core temperature of 37°C and a heart rate of 60–100 beats per minute. Increase in the temperature of the surrounding environment can serve as the basis for the onset of the condition of Hypothermia. Hypothermia acts as one of the most significant barriers being faced by winter athletes and starts initially with an increase in the heart and breathing rate. However, if the condition persists it can lead to reduction in the heart and breathing rate and ultimately results in cardiac failure. Although, jackets are commercially available, they tend to operate manually and furthermore, do not serve the primary purpose of counteracting the condition of hypothermia, particularly experienced by athletes taking part in winter sports. The objective of this study is to design a heating jacket that enables effective counteraction of the condition of Hypothermia. It enables precise measurement of the of core body temperature with the aid of a pyroelectric sensor. Along with this, a pulse rate sensor for detecting the accurate heart rate has been incorporated on the index finger. Five heating pads would get activated to attain optimal temperature, in case the core body temperature of <37°C is detected. If the condition of hypothermia advances to the moderate stage, two additional heating pads will get activated and provide extra warmth to attain normal heart rate along with core body temperature. Overall, this wearable technology serves as a definitive solution to counteract the condition of hypothermia only when the internal parameters exhibit that you actually have it. The results of the study exhibited that this prototype can be utilized for detecting and treating the condition of Hypothermia.

Severe Accidents in Sodium-Cooled Fast Reactors: CFD Sensitivity Studies on the Thermal Ablation of Core-Catcher

The present work aims at testing the CFD capabilities to simulate erosion of materials which interact with a corium mass. The main foreseen applications are the design of external/internal core catchers or in-vessel retentions devices used to mitigate severe accidents for Sodium-cooled Fast Reactors (SFR). 2D axisymmetric simulations of a corium jet impinging a sacrificial solid material show evidence of a pool-effect, previously observed in experiments, which contributes to limit the ablation process. Complementary sensitivities assess the influence of jet diameter, temperature and velocity.

THE SEISMIC RESPONSE OF STRUCTURAL OUTRIGGER SYSTEMS IN TALL BUILDING

One of the advanced structural systems that have been applied in tall buildings to improve the building strength during quake loads is the outrigger system. For that, this research is interested to study different structural system as a vierendeel system and wall beam system when applied them as outrigger which is connected between the internal core walls and the external columns in one or two stories. The outrigger position changed through the tallness of 40 story building and the building response is examined in this research under El-Centro time history earthquake load. All the models are analyzed in Midas-Gen program and the research conclusions were concluded to help researchers to provide more in the field of civil engineering. The inferred parameters as storey drift, story drift ratio and base storey overturning moment are plotted in graphs between the storey number and the outrigger position for each outrigger system. The results showed that, the one storey wall beam structural system is better than two stories vierendeel structural system when these systems applied as outrigger system. The best position for one storey outrigger is about 0.45 of the total building height and for the two stories outrigger, the .20 and .45 of the total building height are the best positions. Overall, the outrigger system is an effective structural system to make the tall buildings withstand through the earthquake loads.

Native flagellar MS ring is formed by 34 subunits with 23-fold and 11-fold subsymmetries

The bacterial flagellar MS ring is a transmembrane complex acting as the core of the flagellar motor and template for flagellar assembly. The C ring attached to the MS ring is involved in torque generation and rotation switch, and a large symmetry mismatch between these two rings has been a long puzzle, especially with respect to their role in motor function. Here, using cryoEM structural analysis of the flagellar basal body and the MS ring formed by full-length FliF from Salmonella enterica, we show that the native MS ring is formed by 34 FliF subunits with no symmetry variation. Symmetry analysis of the C ring shows a variation with a peak at 34-fold, suggesting flexibility in C ring assembly. Finally, our data also indicate that FliF subunits assume two different conformations, contributing differentially to the inner and middle parts of the M ring and thus resulting in 23- and 11-fold subsymmetries in the inner and middle M ring, respectively. The internal core of the M ring, formed by 23 subunits, forms a hole of the right size to accommodate the protein export gate.

3D Printing of Ceramic Shell Molds for Precision Casting of Turbine Blades

Traditionally, the technology used in the production of gas turbine blade castings characterized by a large number of technological conversions, high labor costs with a large amount of manual labor and the need to produce various types of complex and expensive equipment at different stages of production. This work aims to reduce the time and money spent on the manufacturing of ceramic shell shapes — a form suitable for the standard methods of precision casting by traditional heat-resistant nickel alloys. The proposed approached involves obtaining a shell shape with an internal core as a single, non-assembled product, without lengthy and time-consuming design and manufacturing processes involved in forming equipment for the production of castings based on smelted models. The proposed method is based on the use of 3D printing with refractory ceramic pastes. Using both uncooled and cooled blades as examples, models of casting molds were designed, technological processes were developed, and ceramic shell molds were manufactured. Experimental casting into a manufactured ceramic shell mold for an uncooled blade with a bandage shelf was performed and showed satisfactory results.

LINEAR SEARCH ALGORITHM TO BE SOLVED BY PARAMETER LOOP

There are common occasions for finding out required optional data or element from the given algebra of sets and any kind of systems when we are solving practical and informatics tasks. In order to solve these types of tasks or issues, students or researchers have to know about the methodologies for basic understanding which are called tasks for searching. This process is very important as for finding out basic understanding and methodologies, having detailed knowledge of algorithms and searching methods, although there are modern specific technologies and automatic programming systems. When searching methods are programmedfor informatics tasks, necessary abilities such as seeking essential or import of program language operators and making analysis indifference among characterful solving should be owned by students or specialists. Therefore,I set my purpose of thesis of organizing linear searching algorithms by the parameter loop of the programming language C during the discovering process of identifying differences, patterns, and internal core of linear searching methodologies.

From Body Mantle To Internal Core - A Parallel Framework To Organ Systems

A framework describing a body perspective that can be used under Western Medicine (WM) and Chinese Medicine (CM) in parallel would facilitate a concerted look at the body in both perspectives. The major body systems may be viewed as operating systems, while closely interactive organ clusters forming whole body subsystems sub serve life functions. The whole body is viewed in layers: with the Mantle as border zone, the under-layer Interface as interactional zone, the Core with organ systems, and the Deep biostratum of resources. The mantle acts as a barrier and interface, while the under-layer of fascial, circulatory and neurohumoral elements inter-relate with deeper provisions, supporting and stabilizing activities. The operating systems and life vigor subsystems function up to a surface border-zone to interact effectively and adaptively with the surrounding environment. While current academics consider the dynamic brain tightly integrated with the body as a self-organized system, a clinical framework is lacking. This paper provides a more or less seamless framework between social, physical, biochemical and cellular perspectives, which have formerly been dichotomizing with big gaps. With such a framework, WM workers can expand onto using some parts of the CM perspectives, not losing scientific emphasis of cellular studies, while recognizing that whole body processes in many clinical occasions can explain problems and be handled more effectively. This has implications in diagnosis and understanding pathophysiology. Accordingly, a spectrum of practice modes in medicine presented helps to understand clinical approaches, from lesion to complexity treatment.
