Page Numbers : Sch. Bull.; 2016, 2(8): 470-475
DOI : 10.21276/sb.2016.2.8.1
Abstract: In this paper, we propose a non-monotone trust region method for solving equality constrained optimization problem. Unlike the traditional trust region methods, our algorithm uses a new non-monotone strategy. Theoretical analysis indicates that the new method preserves the global convergence under some mild conditions.

Thomas Mione, Segundo Leiva González, Leon Yacher
Page Numbers : Sch. Bull.; 2016, 2(8): 476-484
DOI : 10.21276/sb.2016.2.8.2
Abstract: Discoveries of new-to-science species have rendered outdated the last published list of Jaltomata species of Peru.We recognize eight Jaltomata species in Department Lima: J. andersonii, J. aspera, J. bicolor, J. contorta, J. dentata, J. hunzikeri, J. propinqua, J. umbellata, and J. sinuosa. The latter has not been collected in Department Lima but was included in the key because it is likely to grow in Department Lima. Fruits of at least five of these species (J. aspera, J. bicolor, J. dentata, J. propinqua, J. umbellata) are eaten by people. Two species,J. aspera and J. umbellata, have copious red/orange floral nectar. In lomascommunitiesJ. aspera, J. hunzikeri and J. umbellataflower July–October.However, in the AndesJ. aspera, J. bicolor, J. dentata andJ. propinquaflower mostly from December–April. There are no recent collections of J. contorta and J. hunzikeri and these species may be extinct.

“Kadugolla Community in Karntaka – At the Crossroads”
Page Numbers : Sch. Bull.; 2016, 2(8): 485-487
DOI : 10.21276/sb.2016.2.8.3
Abstract: The Kadugolla community is very backward and even the economic position of men of this community is hopeless and pitiable. In such a scenario one can understand the plight of the women folk. But things have started to change in the recent times and the Kadugolla women have been able to lift themselves up from the perennial state of discrimination and inequality.

Treatment of Lower Lip Mucocele with Scalpel Excision and Laser Technique: A Case Report
Pranav S Patil, M. L. Bhongade
Page Numbers : Sch. Bull.; 2016, 2(8): 488-491
DOI : 10.21276/sb.2016.2.8.4
Abstract: Mucocele is a term used to describe the swelling caused by pooling of saliva at the site of injured minor salivary gland. Various treatment modalities have been present for the management of mucocele, These include excision by a scalpel, laser ablation (CO2, Er, Cr:YSGG), electrosurgery, cryosurgery, medication (gamma-linolenic acid [GLA]), micromarsupialization. This case report present definitive management of lip mucocele.

Roya Vaziri Doghezlou, Alireza Fakharzade Jahromi
Page Numbers : Sch. Bull.; 2016, 2(8): 492-496
DOI : 10.21276/sb.2016.2.8.5
Abstract: Scoliosis deformity is characterized as a lateral deviation of the spine in three-dimensions accompanied by axial rotation of the vertebrae. In this paper by surveying on the mathematical model of spine movement, we simulate the growth of scoliosis disease of a patient by using finite element method for vertebrae T1-T6 of spine. For this purpose by using Newmark method, we first deal the numerical solution of the given mathematical model. We will also explain the growth process of this disease by using geometric drawing in Matlab environment. Moreover, numerical simulations based on the mentioned process are presented.

Implementation of optimizing slice interpolation in medical image using finite difference method
Nasim Khoonkari, Alireza Fakharzadeh Jahromi
Page Numbers : Sch. Bull.; 2016, 2(8): 497-500
DOI : 10.21276/sb.2016.2.8.6
Abstract: Slice interpolation in medical images is one of the important concepts in medical image processing in which many attempts have been made to improve it. In general, it is divided into two groups that are intensity-based interpolation and object-based interpolation. This article is an overview of object-based interpolation, based on image registration. Due to the various types of image registration and curvature registration as the latest one, interpolation is done on the basis of this type of registration. According to this, there would be an optimization problem which is solved by the use of Euler-Lagrange. In this regard, an optimization problem converted into a partial differential equation that is solved by using finite difference method. Then, by applying the solution an optimal displacement vector for moving the image is obtained.

DOI : 10.21276/sb.2016.2.8.8
Abstract: In this paper, an interior point algorithm for linear optimization problem based on a kernel function which has trigonometric function in its barrier term is proposed. By means of some simple analysis tools, we show that our algorithm in large neighborhood of the central path has the best known iteration complexity bound.

Embracing the Human Resource Department Role in Modern Organizations
Beauttah Mwangi Waweru
Page Numbers : Sch. Bull.; 2016, 2(8): 511-514
DOI : 10.21276/sb.2016.2.8.9
Abstract: The roles of the human resource department are cross cutting and hence affect every sphere of an organization. In order for the department to develop, maintain, ensure compliance and contribute to the development of corporate HR policies; it has to be supported. This should be on areas of developing, refining and fine-tuning effective methods in selection of employees and ensuring that the organization has the right people with the desired level of competencies on board. It also has to be embraced and supported by the top management. This should be done at both strategic as well as at operational levels in both corporate and human resource planning where in conjunction with line managers action plans can be developed to help meet present and future needs of an organization.

Cell phone and the mental health of the students- a short review
Prathibha Prasad, Mohamed said Hamed, Radhika Tharoor
Page Numbers : Sch. Bull.; 2016, 2(8): 515-516
DOI : 10.21276/sb.2016.2.8.10
Abstract: The state of mind and mental health makes a huge difference to our overall well-being. Mobile phone usage is alarmingly increasing especially in the younger generation. The younger generation especially is glued to their cell phones and is supposedly a form of addiction according to some studies. There is an integration of machine- man and a growing concern about health as individuals are exposed to electromagnetic field (EMF) emitted by cell-phones. The radio-frequency radiation emitted by cell-phones as placed near to ear has effect on functional changes in the brain and affects cognition and mental well-being. The real concern is about the effect of these radiations on mental health and cognition of students.
