INVOLVEMENT AND COMMUNICATION ON FACE BOOK: EXPLORING INTERACTION PATTERNS OF PERSONALITY AND ADULT ATTACHMENT STYLES

The study is intended to explore individuals’ involvementand interaction on Facebook as an outcome of personality dimensions,and attachment styles. Participants (N=383) Facebook users included 60.3% females with an age range of 18-27 years (means = 22.47±2.91). Results suggested that extraversion (β=.12, p<.05) and neuroticism (β=.15, p<.05) predicted Facebook usage (intensity), and effects of neuroticism is moderated by secure attachment style (β interaction= - .23, p<.01). Social interaction on Facebook was predicted by extraversion (β=.14, p<.05) and the effects was moderated by secure attachment style (β interaction= -.16, p<.05). It is concluded that computer mediated communication on social networking sites is a complex phenomenon and shall be studied as a consequence of interaction between personal and environmental factors

Paper Session I-C - Mapping & Area Estimation of Mangrove & Riverine Forests in Sind Using Remote Sesing Techniques

This paper presents a study on mapping and area estimation of the Mangrove and Riverine forests in Sind, using Remote Sensing techniques. Landsat 5 False Colour Composite and Black & White Prints have been used for manual interpretation. A Mangrove forest map and a Riverine forest map have been prepared on 1:250,000 and 1:1,000,000 scales respectively. From these maps, area estimates have been carried out Mangrove forests have been estimated to be on about 0.52 million acres whereas Riverine forests have been estimated to be on about 0.66 million acres. Results indicate that Remote Sensing techniques can be effectively used for mapping and area estimation of Mangrove and Riverine

(6-Hydroxy-2-{[2-(N-methyl­carbamo­thiol­yl)hydrazin-1-yl­idene-κ2 N 1,S]meth­yl}­phenolato-κO 1)(triphenyl­phosphane-κP)nickel(II) chloride

The deprotonated Schiff base ligand in the title salt, [Ni(C9H10N3O2S)(C18H15P)]Cl, functions as an N,O,S-chelating anion to the phosphine-coordinated nickel(II) atom, which exists in a distorted square-planar geometry. The hy­droxy group forms an intra­molecular O—H⋯O hydrogen bond. The two amino groups of the cation are hydrogen-bond donors to the chloride anion; the hydrogen bonds generate a chain structure running along the b axis

An Overview of Electrical Tree Growth in Solid Insulating Material with Emphasis of Influencing Factors, Mathematical Models and Tree Suppression

Nowadays, the most widely used insulating materials in high voltage equipment such as cables are polymeric insulations due to the numerous merits they possess with regards to electrical performance compared to paper insulations. However, electrical treeing, one of the dielectric pre-breakdown phenomena, has been considered as a major contribution to the failure of insulating polymeric materials. Thus, this paper provides an overview on the factors affecting the initiation and propagation of electrical tree.  Discussions on parameters that affect the growth of electrical treeing such as applied voltage, electric field enhancement, partial discharge, frequency of applied voltage and temperature are given. Some discussions on the various models are also highlighted. The tree related models being discussed herein include Weibull, Lognormal, Johnson SB, Dielectric Breakdown Model, Discharge-Avalanche Model, and Field-Driven Tree Growth. In addition, discussions on the use of nano-sized fillers in polymeric insulating material to inhibit electric treeing are highlighted

1-(2,3,4-Trihydroxy­benzyl­idene)-4-ethyl­thio­semicarbazide

In the title mol­ecule, C10H13N3O3S, the thio­semicarbazide =N—NH—C(=S)—NH– fragment is twisted with respect to the aromatic ring [dihedral angle = 20.5 (1)°]. A weak N—H⋯S hydrogen bond [3.480 (1) Å] links two mol­ecules about a center of inversion to generate a ring. The hydr­oxy groups are engaged in inter­molecular hydrogen bonding; the O—H⋯O and O—H⋯S hydrogen bonds generate a layer motif

1-(2,3,4-Trihydroxy­benzyl­idene)thio­semicarbazide

In the title mol­ecule, C8H9N3O3S, the thio­semicarbazide =N—NH—C(=S)—NH— fragment is twist a different degree of twist in the three independent mol­ecules [dihedral angles = 7.6 (1), 11.6 (1) and 20.7 (1)°]. Intra­molecular O—H⋯N and O—H⋯O hydrogen bonds occur. In the crystal, the hydr­oxy and amino groups are hydrogen-bond donors and the O—H⋯O, O—H⋯S and N—H⋯O hydrogen bonds generate a layer motif
