Development Of Multi-Component Degradable Plastics Through The Combination Of The Sago Starch And Polyethylene/Poly (E-Caprolactone) Blends [TP1180.B55 L732 2007 f rb].

In this research, sago starch (SS),poly(ε-caprolactone) (PCL) were incorporated into low density polyethylene (LDPE). Poly(ethylene-co-acrylic) acid (EAA) was added into the blend to study the effect on thermo-oxidative ageing (TOA).

Dalam kajian ini, kanji sago, poli(ε-caprolacton) (PCL) telah dicampuradunkan dengan polietilena berketumpatan rendah (LDPE)

Effect of Ceramic Dust as Partial Replacement of Cement on Lightweight Foamed Concrete

Disposal of waste into the landfill causes a severe impact on the environment. One of the waste products is ceramic waste. Ceramic waste has some excellent properties in its durability, hardness, and highly resistant to biological, chemical, and physical degradation forces. These excellent properties of the ceramic waste may make it suitable to be used in concrete. This study investigates the effect on the compressive strength of lightweight foamed concrete with different percentage of ceramic dust replacement level towards the cement and three different levels of water-cement ratio. 0%, 5%, 15%, and 25% of replacement level with 0.52, 0.56, and 0.60 water-cement ratios respectively for each replacement level was used as the parameter to investigate the fresh properties, and strength performance of lightweight foamed concrete. The stability and consistency of every mix are studied as well. From this study, it was observed that the incorporation of ceramic waste dust partially replaced the cement did not affect on the fresh properties of the foamed concrete. However, the compressive strength of foamed concrete affected by ceramic waste dust partially replaced the cement

The Roles of Information Technology in Organizational Capability Building: An IT Capability Perspective

The objective of this study is to examine why and under what situations certain information technology resources can generate positive organizational outcomes. To achieve this, we adopt the organizational capability perspective. Based on this perspective, IT can be viewed as a functional capability that forms high- level dynamic capability in the copresence of other functional capabilities and resources. A process-oriented view is used to examine how this capability-formation process happens inside organizations. For the high-level dynamic capability, we focus on organizational agility by considering the contemporary business environment. We propose a conceptual framework regarding the roles of IT capabilities in organizational agility building. In our framework, IT capabilities can create organizational agility through two paths: (1) capability building through process improvement or innovation and (2) capability creation through innovative adoption of new IT capabilities. As part of the framework development, we suggest a method to define organizational IT capabilities in multiple levels of analysis, which allows us to evaluate IT capabilities at the information systems strategy level as well as the functional technology level. The proposed conceptual framework serves as a theoretical foundation of further empirical studies

IT-Enabled Dynamic Capability Creation: A Perspective on Exploitative vs. Explorative IT Utilization

By focusing on today’s highly competitive and rapidly changing business environment, this study theorizes how organizations can create their dynamic capability from the utilization of information technology (IT) resources. The organizational exploitation and exploration perspective is adopted as the central theoretical basis of this study. A reflection on the exploitation and exploration of organizational IT management provides the possibility for theorizing multiple paths for IT-enabled dynamic capability creation. Under our theoretical development, the multiple paths involve different types of IT utilization capabilities that, in conjunction with organizational IT resources and other non-IT factors, lead to organizational dynamic capability. This study provides a theoretical basis for the role of IT in creating organizational dynamic capability. Specifically, it reveals the multiple types of interrelations between organizational IT resources and their utilization capabilities. This study serves as a basis for further empirical studies

Unraveling the nuclear and chloroplast genomes of an agar producing red macroalga, Gracilaria changii (Rhodophyta, Gracilariales)

Agar and agarose have wide applications in food and pharmaceutical industries. Knowledge on the genome of red seaweeds that produce them is still lacking. To fill the gap in genome analyses of these red algae, we have sequenced the nuclear and organellar genomes of an agarophyte, Gracilaria changii. The partial nuclear genome sequence of G. changii has a total length of 35.8 Mb with 10,912 predicted protein coding sequences. Only 39.4% predicted proteins were found to have significant matches to protein sequences in SwissProt. The chloroplast genome of G. changii is 183,855 bp with a total of 201 open reading frames (ORFs), 29 tRNAs and 3 rRNAs predicted. Five genes: ssrA, leuC and leuD CP76_p173 (orf139) and pbsA were absent in the chloroplast genome of G. changii. The genome information is valuable in accelerating functional studies of individual genes and resolving evolutionary relationship of red seaweeds

The Impact of Risk Preference on Auction Mechanism: An Experimental Approach

Auction is an important exchange mechanism from both the practical as well as theoretical perspective. The advent of the Internet has opened up new research arena for the theory of auctions. In this paper, we investigate the bidding behavior of subjects under three mechanisms, namely, the first-price, second-price, and third-price sealed-bid auctions, taking into consideration the risk profile of the subjects. In particular, we address the question of whether third-price auctions generate the highest expected revenue for the seller when bidders are risk seeking (Monderer and Tennenholtz (2000)
