We investigate the properties of the excess charge(electron, hole) introduced into a two-strand biomolecule. We consider the possibility that the stable soliton excitation can be formed due to interaction of excess charge with the phonon subsystem. The influence of overlap of the molecular orbitals between adjacent structure elements of the macromolecular chain on the soliton properties is discussed. special attention is paid to the influence of the overlapping of the molecular orbitals between structure elements placed on the different chains. Using the literature values of the basic energy parameters of the two-chain biomolecular structures, possible types of soliton solutions are discussed.

The development of cultural tourism in Ubud has contributed to the rise of its image as a culinary destination. surprisingly, the ascent of this new image was mainly reinforced by women＇s role in practicing local culinary entrepreneurship. Even it is acknowledged that culture is a dynamic entity, Balinese women get very rare exposure in the culinary world as it is commonly known mastered by men. On the other hand, culinary tourism has now taken a major part in many tourist destinations. As an emerging trend, culinary tourism faces the fears the world is surrendering to： McDonaldization and cultural homogenization. With this emerging trend, Ubud＇s cooking culture and tastes own a major potential in promoting the destination. However, as a part of culture local culinary in Ubud is rarely being studied or visible to the academic literatures. Becoming fertile terrain for researches that explore the discipline of cultural tourism, very little research also has been carried out into gender dimension in culinary tourism in Ubud. This paper is a first attempt to unpack women＇s role in promoting Ubud＇s image as an emerging culinary destination. Using qualitative method, the paper explores women who have not only succeeded in lifting local culinary as traveller＇s preferences but also in opening up job opportunities in rural areas. The data presented in this article were collected through observation and in-depth interviews of four leading Ubud women who have run successful local culinary outlets or restaurants offering local dishes. The four women surveyed are the owner of Kedewatan Chicken Rice （Nasi Ayam Kedewatan） Ibu Mangku, the owner of the infamous suckling pig in Ubud Ibu Oka, the owner of Bebek Bengil Agung Raka suenl, and the owner of Paon Bali cooking class Ibu Puspawati. Combining literature reviews and data obtained through observation and in-depth interviews, this paper aims to provide an overview of the potential of culinary tourism to contribute to the gender e

The three-dimensional Klein-Gordon equation is solved for the case of equal vector and scalar second Poschl-Teller potential by proper approximation of the centrifugal term within the framework of the asymptotic iteration method. Energy eigenvalues and the corresponding wave function are obtained analytically. Eigenvalues are computed numerically for some values of n and It is found that the results are in good agreement with the findings of other methods for short-range potential.

Manufacturing industries are facing challenges in the implementation of agile manufacturing in their products and processes. Agility is widely accepted as a new competitive concept in the manufacturing sector in fulfilling varying customer demand. Thus, evaluation of agile manufacturing in industries has become a necessity. The success of an organisation depends on its ability to manage finding the critical success factors and give them special and continued attention in order to bring about high performance. This paper proposes a set of critical success factors （CsFs） for evaluating agile manufacturing considered appropriate for the manufacturing sector. The analytical hierarchy process （AHP） method is applied for prioritizing the success factors, by summarizing the opinions of experts. It is believed that the proposed CsFs enable and assist manufacturing industries to achieve a higher performance in agile manufacturing so as to increase competitiveness.
