Relationship of Project Scope, Top Management Support, Skilled and Competent Project Team and Project Manager’s Leadership Qualities with Information Technology Projects
The aim of this research is to find out the relationship of Project Scope, Top Management Support, Skilled and Competent Project Team and Project Manager’s Leadership Qualities with Information Technologies Projects. It is widely reported from IT industry that many IT projects fail, this research is going to find out the elements which might be responsible for the failure. The research is based on empirical survey, based on questionnaire. The result shows that there are no relationships between Top Management Support with Information Technologies Projects. All of the other variables have significant relationships with IT Projects. The research results can be used by IT sector organizations and by management in order to decrease the chances of IT projects failure. Keywords: Project Scope (PS), Top Management Support (TMS), Skilled & Competent Project Team (SCPT), Project Manager’s Leadership Qualities (PMLQ) and Information Technologies Projects (ITP)

Survival benefit of surgery in recurrent glioblastoma multiforme
There is an ongoing debate regarding role of surgery for recurrent glioblastoma multiforme (GBM). Older literature hinted at only modest survival benefits with surgery and a high rate of morbidity. However, more recent literature suggests better survival that may be attributed to better surgical techniques and better options in adjuvant treatment. Herein the authors review recent literature with regards to the possible role of surgery in recurrent GBM and also look into the key factors impacting second surgery
Asymptomatic Ileal Schwannoma presenting as a Mesenteric Tumour : Case report and review of literature
A schwannoma is a benign tumour which arises from the schwann cells of the central or peripheral nervous system. Common sites include the head and limbs; it is rare that this tumour arises from the gastrointestinal tract’s neural plexus. It is even rarer to find the ileum as the site of origin. We report a patient who presented with a central abdominal mass which was preoperatively diagnosed as a mesenteric tumour. However, immunohistochemistry of the surgically-removed specimen proved it to be a benign ileal schwannoma
Synthesis, characterization and pharmacological evaluation of mixed ligand-metal complexes containing omeprazole and 8-hydroxyquinoline
Purpose: To synthesize a series of mixed ligand-metal complexes and to evaluate their alkaline phosphatase inhibitory capacities, antioxidant potential and antimicrobial activities.Method: Mixed ligand-metal complexes of Zn (II), Ni (II), Co (II), Cu (II), omeprazole and 8- hydroxyquinoline were synthesized. The ligand-metal complexes were characterized by various physicochemical techniques, including elemental analysis, magnetic susceptibility, scanning electron microscope (SEM), mass spectrometry (EI-MS), ultraviolet-visible (UV-Vis) spectrophotometry, Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (1H-NMR) and conductance studies. The new compounds were also investigated for their alkaline phosphatase (ALPs) inhibition, 2,2’-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging and antimicrobial activities.Results: Spectroscopic studies revealed the chemical composition of synthesized compounds as well as the bidentate bonding behavior of the coordinating ligands with metal ions. Conductance measurement suggested that the metal complexes were non-electrolytes. Ni(II) complex exhibited antioxidant activity (30.48 ± 0.32 μM) higher than those of BHT (standard) and other complexes. Stronger inhibition of ALPs by Ni (II) mixed ligand complex compared to the other complexes was evident. The synthesized compounds showed moderate to very good antimicrobial activity against bacterial strains, i.e., Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Actinomyces viscosus, Staphylococcus aureus, Bacillus subtilis; as well as against the fungal strains, Candida albicans, Aspergillus flavus and Aspergillus niger.Conclusion: All the mixed ligand complexes demonstrate higher antioxidant, ALPs-inhibitory and antimicrobial activities than their corresponding ligands. This indicates their therapeutic potential as future drug candidates for the concerned diseases.Keywords: Omeprazole, 8-Hydroxyquinoline, Mixed-ligand complexes, Alkaline phosphatase, Bidentate bonding behavior
Table Structure Extraction with Bi-directional Gated Recurrent Unit Networks
Tables present summarized and structured information to the reader, which
makes table structure extraction an important part of document understanding
applications. However, table structure identification is a hard problem not
only because of the large variation in the table layouts and styles, but also
owing to the variations in the page layouts and the noise contamination levels.
A lot of research has been done to identify table structure, most of which is
based on applying heuristics with the aid of optical character recognition
(OCR) to hand pick layout features of the tables. These methods fail to
generalize well because of the variations in the table layouts and the errors
generated by OCR. In this paper, we have proposed a robust deep learning based
approach to extract rows and columns from a detected table in document images
with a high precision. In the proposed solution, the table images are first
pre-processed and then fed to a bi-directional Recurrent Neural Network with
Gated Recurrent Units (GRU) followed by a fully-connected layer with soft max
activation. The network scans the images from top-to-bottom as well as
left-to-right and classifies each input as either a row-separator or a
column-separator. We have benchmarked our system on publicly available UNLV as
well as ICDAR 2013 datasets on which it outperformed the state-of-the-art table
structure extraction systems by a significant margin.Comment: Proceedings of the 15th International Conference on Document Analysis

Microwave-assisted solvent free efficient synthesis of 1,3,4-oxadiazole-2(3H)-thiones and their potent in vitro urease inhibition activity
An efficient solvent free microwave assisted synthesis of 5-substituted-1,3,4-oxadiazole-2(3H)-thiones (2a-2r) from hydrazides and carbon disulfide has been accomplished in good to excellent yield. The urease inhibition activity of the resulting compounds was investigated. Preliminary bioassay indicated that the compound 2j bearing 2-bromo substituent is the most active inhibitor exhibiting IC50 12.60 ± 0.92 μM
Cost Comparison between Laparoscopic and Open Appendectomies in Children
Objectives: Laparoscopic appendectomy (LA) for children has become very popular and is routinely performed in most health care centres around the world. The cost of surgical procedures is always a concern for patients and health care providers. This study compares, the total cost of open appendectomy (OA) with LA in children who required an appendectomy for acute appendicitis. Suitable and safe cost-effective techniques were also explored to reduce the cost of these procedures. Methods: The medical records of all the children (ranging between 0 and 12 years) at Sultan Qaboos University Hospital in Oman, who required OA or LA from June 2009 to July 2011, were reviewed. Results: LA were performed in 75 patients while OA were done in 34. Patients from the OA and LA groups were age- and gender-matched. The average operative time was 76 minutes for LA and 49 minutes for OA (P <0.001) while the average hospital stay was 3.14 days for LA and 2.15 days for OA (P = 0.08). The average cost of the two procedures was Omani riyals (OMR) 534 for LA and OMR 343 for OA (P = 0.00). The complication rate following procedures was lower in the case of LA, however this was not statistically significant (LA = 8% versus OA = 11.7 %, P = 0.32). Conclusion: LA are costlier procedures than OA, however they are as safe as OA, and do not increase morbidity or the duration of hospital stay
Role of extent of resection on quality of life in patients with newly diagnosed GBM
Glioblastomas known for their adverse outcomes are most reportedly managed by surgical resection. Studies on the impact of (Extent of Resection) EOR against Quality of Life (QOL) are very limited. We have collected data from recent studies in this review to extract a general consensus among the neurosurgeons regarding the EOR. Key parameters like functional independence, neurocognitive improvements and global health status have been explored in the context of QOL. The currently available data suggests that an increased EOR may help improve QOL in GBM patients. With the help of recent advancements it may be possible to attain a better extent of resection while operating on GBMs
