Molecular characterization, cloning and sequencing of coat protein gene of a Pakistani potato leaf roll virus isolate and its phylogenetic analysis
Total RNA was extracted from potato leaf roll virus (PLRV) positive potato plants and complementary DNA were synthesized. Reverse transcriptase polymerase chain reaction (RT-PCR) based detection conditions were optimized by using coat protein (CP) gene specific primers. A 346 bp amplicon of PLRV- coat protein (CP) gene was amplified. Amplified CP-gene of PLRV was cloned in TA cloning vector, PCR ® 2.1. The clone was confirmed subsequently through restriction digestion analysis. PCR amplification used cDNA clone as a template and nucleotide sequencing. Expected nucleotide sequence of amplified PLRV-CP gene show homology of 94 to 97% when compared to the sequences already reported in GenBank database. This explored novel PLRV-CP gene was submitted at NCBI GenBank for characterization of PLRV Pakistani isolate (Accession No. JN039286). Phylogenetic analysis was also carried out and tree was made by using MEGA 4.0.Key words: Potato, potato leaf roll virus (PLRV), coat protein (CP) gene, reverse transcriptase polymerase chain reaction (RT-PCR), PLRV-CP Pakistani isolate

A summary of bibliometric analysis on the publication trends in technology roadmapping
Technology roadmapping is “a technique to capture diverse information in technology evolution and new product development” (Petrick & Echols, 2004, p.89). It is part of technology planning that deal with increasing competitive environment (Garcia & Bray, 1997). Technology roadmapping is crucial for creating alignment between technology and
organizational goals (Phaal, Farrukh, & Probert, 2005). One of the applications is to support strategic planning in relations to technology, product, and market (Phaal, Farrukh, & Probert, 2004). It can also be applied for service planning, capability planning, longrange planning, knowledge asset planning, program planning, process planning, and integration planning (Phaal, Farrukh, & Probert, 2001). The initial works on technology roadmapping was appeared for the first time in the late 70’s (Phaal, Farrukh, & Probert,
2005). With over two decades of literatures, the ground works of technology roadmapping have been well established. As a result, this study will summarize the publication trends in technology roadmapping based on the bibliometric analysis of references
Understanding the effects of technological advancement (Internet of Things) on value co-creation and firm performance
This paper focuses on the effects of technological advancement in the relationships between value creation and firm performance. Specifically, this paper will explain how the concept of internet of things (IoT) can influence value co-creation and co-destruction towards firm performance from the perspective of resource-based view
(RBV) and service-dominant (S-D) logic. This paper is motivated to discuss on the mentioned relationships due to four reasons. Firstly, although value co-creation has always been associated with positive implications on consumers (Terblanche, 2014); there are also some possible negative implications related to them (Grönroos, 2012). The same observation could also be happened to firm performance. For instance,
increasing consumer participation will reduce firm controls on the outcome of the process. This situation would be ended up co-destructing the value through the very same consumer-firm interactions that are used in value co-creation
(Terblanche, 2014). Therefore, the possibility of value co-destruction should not be overlooked (Plé & Cáceres, 2010) as it may as well affect the firm performance (Alexander, 2012). Despite of that, the numbers of studies focusing on both value
co-creation and co-destruction in a single topic is still relatively low. Since the concept of value co-destruction is still in blur (Plé & Cáceres, 2010), the interrelationships between value co-creation and co-destruction need to be further explored

Publication trends in technology roadmapping
This study aims to identify the trends in technology roadmapping based on the bibliometric analysis of more than two decades of references. The analysis focused on the types of publications (e.g., journal and conference), contexts of publications (e.g., international and national), and key themes (e.g., NPD and R&D) extracted into six groups of five-year interval time-periods each.The analysis on 699 references has revealed the interest on technology roadmapping was only started to increase since 1996-2000 time-periods with 38 publications, and have reached the highest peak with 305 publications in 2006-2010 time-periods.In details, both journal and conference were almost equal in numbers of publications, in which Technological Forecasting and Social Change was found to be the top journal, while IEEE is the top organizer with PICMET as the leading conference. Despite of most of the articles were written with generic titles, 12 of them have been identified written on international context (e.g., Asia Pacific and Europe), 78 on national context (e.g., China and Japan), and 14 on organizational
context (e.g., Siemens and Motorola).In addition, the analysis has also found 17 key themes of studies led by ICT, innovation, and energy. Although the analysis was based on a single source of database with some limitations, future studies should pay more attention on the importance of technology roadmapping on the international context, emphasis on developing countries on the national context, focus on SME on the organizational context, and explore the applications of technology roadmapping on the non-technological themes
Value co-creation, co-destruction, and firm performance: A proposed mediation of the internet of things
Value co-creation is a study on consumer-firm interactions, where consumers can be
actively involved with firms in designing, developing, marketing, distributing, and (or)
selling of products to personalize their service experiences. In contrast, value codestruction
exists due to imbalance involvement between consumers and firm in cocreating of value as a result of misuse of resources.Previous studies have suggested while value co-creation will increase firm performance, value co-destruction will do just the opposite of that. In the meantime, the internet of things (IoT) has becoming important topic to study how value co-creation and co-destruction can be created. Therefore, it was expected the effects of value co-creation and co-destruction on firm performance can be better understood with IoT.However, study that has looked into the mediating effects of
IoT in the relationships between value co-creation and co-destruction on firm performance in a single topic is still hard to find.In line with the research gap, this paper will be investigating the aforementioned issue by building a conceptual framework with research propositions.This paper is proposing that IoT will positively improve the effect of value co-creation on firm performance, while at the same time reducing the negative
effect of value co-destruction.This paper is expected to enhance our knowledge on the relationships between value co-creation and co-destruction, improve our understanding on the effects of IoT on firm performance, and promotes resource-based view (RBV) to complement Service-Dominant (S-D) logic at explaining superior firm performance
Graphene's Application to Boiler's Fabrication and Design
Problem Statement: Boilers have enormous applications and usefulness in power generation. It is to be reckoned as an all time employee in power generation sector and it is a device to create steam by applying heat energy to the water. It can also be used as steam generators. The pressure vessel of a boiler usually made of steel (or alloy steel), or historically of wrought iron is extremely exposed to the corrosion and embrittlement. This causes additional problems like boiler breakdown which can cost thousands of dollars in equipment repairs, as well as hundreds of thousands of dollars for additional property damage and business income losses. Despite numerous methods to minimize this problem the world hasn’t come up with a concrete solution. Still today boiler accidents cause heavy economic and personal losses. Can we ever come up with a solution to almost nullify this problem with all the advancements in Material Sciences in recent years?Proposed Solution: We aim at coating the inner side of boiler with deposition of membrane of oxide of recently discovered super-material graphene. Researchers found that a multilayer of graphene dioxide when stacked up together act as perfect molecular sieves when immersed in water, blocking all molecules or ions with a hydrated size larger than 4.5 Å. Caustic Embritllement causing prime agent NaOH clearly is not contained within limits described in its molecular form. Also we found that except for water vapors it does not allow any other gas to bypass it hence we ideate that prime corrosion causing agents like dissolved O2 and C02 will not interact with boiler material and hence will significantly remove boiler corrosion.Conclusion: Incorporating this hypotheses we tend to believe that prime boiler enemies will exert their least presence on boiler's functioning and its life. Its working life will be enhanced by several times. We believe that use of the latest advancement witha rather primitive subject of boilers will create a wave within boiler industries and help them to enhance boilers working and increase its life. Also it will eliminate the causticity of boiler water
