North Carolina State University: Implementing ERP Student Modules
Authors: Bradford Marianne 
Published: September 2011

ABSTRACT
The purpose of this case is to describe the benefits and challenges of an Enterprise Resource Planning (ERP) system at a higher education institution (HEI). The case also focuses on IT risk and systems security issues inherent in an ERP system. The case begins with the implementation of financials and HR modules at North Carolina State University, a land-grant institution with 33,000 students. This background sets the stage for the main focus of the case: the implementation of the ERP Student modules, which required a major overhaul of information systems, including admissions, student financials, and registration and records. Concluding the case is a recent dilemma facing NCSU—the potential merging of ERP systems with The University of North Carolina at Chapel Hill. Students have the opportunity to practice problem-solving skills with regards to this dilemma, as well as offer their opinions on the strengths and weaknesses of the Student implementations.
Recognition and Management of Complications During Moderate and Deep Sedation. Part 2: Cardiovascular Considerations
Authors: Becker Daniel E , Haas Daniel A 
Published: September 2011

Abstract
The risk for cardiovascular complications while providing any level of sedation or general anesthesia is greatest when caring for patients already medically compromised. It is reassuring that significant untoward events can generally be prevented by careful preoperative assessment, along with attentive intraoperative monitoring and support. Nevertheless, providers must be prepared to manage untoward events should they arise. This continuing education article will review cardiovascular complications and address their appropriate management.
Analysis of Oxygen Saturations Recorded During Dental Intravenous Sedations: A Retrospective Quality Assurance of 3500 Cases
Authors: Viljoen Andre , Byth Karen , Coombs Malcolm , Mahoney Greg , Stewart Douglas 
Published: September 2011

Abstract
The death of a patient under sedation in New South Wales, Australia, in 2002 has again raised the question of the safety of dental sedation. This study sought answers to 2 questions: Can safe oxygen saturation levels (≥94%) be consistently maintained by a single operator/sedationist? Does the additional use of propofol, in subanesthetic doses, increase the risk of exposure to hypoxemia? Three thousand five hundred cases generated between 1996 and 2006 were randomly examined and divided into 2 subcohorts: 1750 patients were sedated with midazolam and fentanyl, and 1750 patients received propofol, in subanesthetic increments, in addition to midazolam and fentanyl. Initial sedation was established using midazolam and fentanyl in both subcohorts. The second subcohort received propofol during times of noxious stimulation. Patient exposure to 2 or more oxygen desaturations below 94% was uncommon. The variables that were significantly associated with low saturations were age, gender, and weight. Neither the dose of midazolam nor the additional use of propofol was a significant risk factor. ASA classification (I or II) was not a determinant of risk. The data, within the limitations of the study, showed that a single operator/sedationist, supported by a well-trained team of nurses, can consistently maintain safe oxygen saturation levels. The additional use of propofol did not increase exposure to hypoxemia.
Nasal Foreign Body: An Unexpected Discovery
Authors: Yasny Jeffrey S , Stewart Stacy 
Published: September 2011

Abstract
Nasal foreign bodies may result from the abundant availability of tiny objects in our society and a curious child exploring his or her nasal cavities. An inserted object that is not witnessed or retrieved can remain relatively asymptomatic or cause local tissue damage and potentially yield more serious consequences. An unusual case of a young child who presented for dental rehabilitation under general anesthesia is described. Immediately prior to the nasotracheal intubation, an unanticipated foreign body was detected and safely removed before any injury occurred. This case report discusses the presentation and pathophysiology of nasal foreign bodies. Moreover, applicable suggestions are provided to aid in the prevention and management of the unexpected discovery of a nasal foreign body after the induction of general anesthesia.
Comparison of temporospatial and kinetic variables of walking in small and large dogs on a pressure-sensing walkway
Authors: Kim Jongmin , Kazmierczak Kris A. , Breur Gert J. 
Published: September 2011

Abstract
Objective—To compare temporospatial variables (TSVs) and kinetic variables (KVs) for fore-limbs and hind limbs of small and large dogs of various breeds during walking and to determine associations among body weight (BW), TSVs, and KVs in these groups.
Animals—12 adult dogs with no evidence of lameness.
Procedures—Dogs (grouped according to BW as small [< 10 kg; n = 6] or large [> 25 kg; 6]) were walked in a straight line at their preferred velocity on a wooden platform with an embedded pressure-sensing walkway. Five valid trials were analyzed for each dog; mean TSVs and KVs were determined for each group. The TSVs and KVs for forelimbs and hind limbs were compared between groups, and correlations among BW, TSVs, and KVs were determined.
Results—Small dogs had significantly smaller TSVs and KVs than did large dogs. Temporal variables of small dogs and absolute vertical force variables of small and large dogs increased as BW increased. However, normalized peak vertical force and weight distribution values among the 4 limbs were similar between groups.
Conclusions and Clinical Relevance—Substantial similarities and differences were detected in gait characteristics between small and large dogs. Results indicated TSVs and KVs can be used for comparison of the walking gait between dogs or for comparison of variables between limbs in an individual dog. Use of the pressure-sensing walkway is a simple method for acquisition of TSVs and KVs for large and small dogs.
The k-Fibonacci matrix and the Pascal matrix
Authors: Falcon Sergio 
Published: September 2011

Abstract
We define the k-Fibonacci matrix as an extension of the classical Fibonacci matrix and relationed with the k-Fibonacci numbers. Then we give two factorizations of the Pascal matrix involving the k-Fibonacci matrix and two new matrices, L and R. As a consequence we find some combinatorial formulas involving the k-Fibonacci numbers.
On (p, 1)-total labelling of 1-planar graphs
Authors: Zhang Xin , Yu Yong , Liu Guizhen 
Published: September 2011

Abstract
A graph is 1-planar if it can be drawn on the plane so that each edge is crossed by at most one other edge. In this paper, it is proved that the (p, 1)-total labelling number of every 1-planar graph G is at most Δ(G) + 2p − 2 provided that Δ(G) ≥ 8p+4 or Δ(G) ≥ 6p+2 and g(G) ≥ 4. As a consequence, the well-known (p, 1)-total labelling conjecture has been confirmed for some 1-planar graphs.
Giant cell formation: the way to cell death or cell survival?
Authors: Horbay Rostyslav , Stoika Rostyslav 
Published: September 2011

Abstract
The study of giant cells in populations of different tumor cells and evaluation of their role in cancer development is an expanding field. The formation of giant cells has been shown to be followed by mitotic catastrophe, apoptosis, necrosis, and other types of cell elimination. Reports also demonstrate that giant cells can escape cell death and give rise to new cancer cells. However, it is not known if the programmed cell death is involved in this type of cell cycle disorders. Here we describe principal events that are observed during giant cell formation. We also consider the role of giant cells in cancer development, taking into account both published work and our own recent data in this field.
Metallic Foreign Body in a Patient With Knee Pain
Authors: Croy Theodore 
Published: September 2011

The patient was a 26-year-old man with a history of a nonhealing, complicated right clavicle fracture. He also complained of right medial knee pain that was thought to be insidious in onset and made worse during magnetic resonance imaging, which was done to evaluate the status of the right clavicle fracture. Subsequent to the patient reporting his right knee pain to his orthopaedic surgeon, magnetic resonance imaging of the right knee was ordered. Anterior-to-posterior and lateral radiographs were then ordered by the physical therapist, which identified a radioopaque foreign body along the medial knee within the subcutaneous tissues.

Resection of infantile brain tumors after neoadjuvant chemotherapy: the St. Jude experience
Authors: Van Poppel Mark , Klimo Paul , Dewire Mariko , Sanford Robert A. , Boop Frederick , Broniscer Alberto , Wright Karen , Gajjar Amar J. 
Published: September 2011

Object
Brain tumors in infants are often large, high grade, and vascular, making complete resection difficult and placing children at risk for neurological complications and excessive blood loss. Neoadjuvant chemotherapy may reduce tumor vascularity and volume, which can facilitate resection. The authors evaluated how an ongoing institutional prospective chemotherapy trial would affect patients who did not have a gross-total resection (GTR) immediately and who therefore required further surgical intervention to achieve definitive tumor resection.

Methods
Thirteen infants (4 girls and 9 boys) who were enrolled in an institutional protocol in which they were treated with multiagent chemotherapy (methotrexate, vincristine, cisplatin, and cyclophosphamide with vinblastine for high-risk patients) subsequently underwent second-look surgery. The primary outcome was extent of resection achieved in postchemotherapy surgery. Secondary outcomes included intraoperative blood loss, radiographic response to the chemotherapy, complications during chemotherapy, and survival.

Results
Three infants underwent biopsy, 9 underwent subtotal resection, and 1 patient did not undergo surgery prior to chemotherapy. On subsequent second-look surgery, 11 of 13 patients had a GTR, 1 had a near-total resection, and 1 had a subtotal resection. In each case, a marked reduction in tumor vascularity was observed intraoperatively. The average blood loss was 19% of estimated blood volume, and 6 (46%) of 13 patients required a blood transfusion. Radiographically, chemotherapy induced a reduction in tumor volume in 9 (69%) of 13 patients. Emergency surgery was required in 2 patients during chemotherapy, 1 for intratumoral hemorrhage and 1 for worsening peritumoral edema. The average follow-up period for this cohort was 16.5 months, and at last follow-up, 4 patients (31%) had died, 1 patient had progressive metastatic spinal disease, and the rest had either no evidence of disease or stable disease.

Conclusions
A GTR of pediatric brain tumors is one of the most important predictors of outcome. The application of the authors' neoadjuvant induction chemotherapy protocol in a variety of tumor types resulted in devascularization of all tumors and volume regression in the majority, and subsequently facilitated resection, with acceptable intraoperative blood loss. Intracranial complications may occur during chemotherapy, ranging from incidental and asymptomatic to life threatening, necessitating close monitoring of these children.

Published: September 2011

Object
Cerebral proliferative angiopathy (CPA) has been morphologically distinguished from classically appearing brain arteriovenous malformations (AVMs) by exhibition of functional brain parenchyma that is intermingled with abnormal vascular channels. The presence of oligemia in this intralesional brain tissue may suggest ischemia, which is not detected in classic brain AVMs. The authors hypothesized that patients with CPA would exhibit a greater impairment of cerebrovascular reserve in neuronal tissue surrounding the true nidus compared with those with brain AVMs.

Methods
Four patients with CPA, 10 patients with brain AVMs and seizures, and 12 young healthy individuals were studied. The 4 patients with CPA underwent blood oxygen level–dependent MR imaging examinations while applying normoxic step changes in end-tidal CO2 to obtain quantitative cerebrovascular reactivity measurements.

Results
Patients with a CPA lesion exhibited severely impaired perilesional cerebrovascular reserve in comparison with patients with brain AVMs and seizures (0.10 ± 0.03 vs 0.16 ± 0.03, respectively; p < 0.05), and young healthy individuals (0.10 ± 0.03 vs 0.21 ± 0.06, respectively; p < 0.01)

Conclusions
This study demonstrated severely impaired cerebrovascular reserve in the perilesional brain tissue surrounding the abnormal vessels of patients with CPA. This finding may provide an additional means to distinguish CPA from classic brain AVMs.
Preparation and Preliminary Study on Irradiated and Thermally Treated Polypropylene (PP) - Styrene Butadiene Rubber (SBR) Composite

Published: September 2011

The tensile strength (TS) and elastic modulus (ES) of non-irradiated (thermally treated) and irradiated Polypropylene (PP) - styrene butadiene rubber (SBR) composites were studied. The content of SBR (mass %) on PP and radiation dose play an important role on tensile strength and modulus of elasticity of PP-SBR composites. Tensile strength (TS) decreased markedly on increasing the SBR content on PP and even on exposing to radiation. The elastic modulus (EM) of PP-SBR composite has a tendency to increase with radiation dose and aging time but decreases with SBR loading. The water uptakes increase with SBR loading which accelerate with aging.Keywords: Polypropylene; Styrene butadiene rubber; Tensile strength; Elastic modulus.© 2011 JSR Publications.

Published: September 2011

The experiment was conducted with forty four pre-pubertal stages female lambs of 12.5±2.5 kg average live weight and 7.5±0.5 months of average age. Animals were equally and randomly allocated into two feeding groups, intensive and semi-intensive feeding systems with 22 animals in each group. Under intensive system, animals were fed concentrate mixture (15.0% crude protein (CP); 11 MJ metabolizable energy (ME)/kg dry matter (DM)) at the rate of 1.5% of live weight with ad libitum green grass from May to November and supplied urea molasses straw (UMS) in place of green grass from December to April. There were no significant differences (p > 0.05) in service per conception, litter size, lambing interval, gestation length, service period, birth weight and weaning weight between intensive and semi-intensive feeding system. Reproductive traits and productive traits were not affected by feeding system. Conception rate was higher (98.0%) in semi-intensive system than intensive system (83.0%). On the other hand lamb survivability was higher in intensive system than in semi-intensive system. The semi-intensive feeding system is found to be better to rear sheep for commercial purpose compared to intensive feeding system.

A series of thermally stable organic polymers [poly(2,5-diethynylpyridine] (5), [poly(1,4- diethynyl benzene)] (6), [poly(2,5-dialkyl-p-phenyleneethynylene)] (7), and [poly(p,p-diethynylbiphenyl)] (8), were synthesized by the reaction between diterminal aryleneethynylene, [HCCArCCH] {Ar = C5H5N (1); Ar = C6H6 (2); Ar = C6H4(CH3)2 (3); Ar = C6H4-C6H4 (4)} and CuCl in pyridine by Hay’s oxidative coupling method. Then the organometallic polymers [Ph (PnBu3)2Pt-C≡C-(Ar-C≡C-C≡C)n-Pt((PnBu3)2Ph] {Ar = C5H5N (9); Ar = C6H6 (10); Ar = C6H4(CH3)2 (11); Ar = C6H4-C6H4 (12)} were synthesized by the reaction of organic polymers 5, 6, 7 and 8 with metal precursor (PnBu3)2 PtPhCl in diethylisopropileamine with good yield. These metal-linked polymers were characterized by IR, 1H-NMR, 13C-NMR and 31P-NMR spectra. Finally the molecular weight of the organometallic polymers (9, 10, 11 and 12) was determined by gel permeation chromatography (GPC). It is clearly observed from GPC that the polymers were synthesized with different degree of polymerization. Keywords: Organometallic polymers; Hay’s Oxidative coupling; GPC. © 2011 JSR Publications.

Bangladesh is one of the tea producing countries of the world. It has 163 tea estates. Rangapani is a low yielding tea estate relative to other neighboring tea estates of Chittagong district in Bangladesh. A total 54 soil samples were collected from six different hills and three topographic positions having different depths of Rnagapanni Tea-Estate. Physico-Chemical properties of soils such as active acidity, reserve acidity, cation exchange capacity and clay content of the collected soil samples were determined. The measured parameters of the soil samples were plotted and analyzed with reference to site and topography. The parameters have been found to vary with sampling sites, depths and topography. Active acidity and reserve acidity were very low, with some exceptions compared to the optimum range for tea cultivation. Sand, silt, clay and cation exchange capacity (CEC) were found in reasonable range Keywords: Soil; Active acidity; Reserve acidity; Cation exchange capacity; Clay content. © 2011 JSR Publications.

Published: September 2011

A numerical study is conducted to investigate the transport mechanism of mixed convection in an inclined lid-driven triangular enclosure subject to cooling at the inclined right surface and simultaneous heating at the base surface filled with nanofluids. Fluid mechanics and conjugate heat transfer, described in terms of continuity, linear momentum and energy equations, are predicted by using the Galerkin finite element method. Numerical results are obtained for a wide range of parameters such as the Richardson number, tilt angle, and copper-water nanofluids is used with Prandtl number, Pr = 6.2. The streamlines, isotherm plots and the variation of the average Nusselt number at the hot surface as well as average fluid temperature in the enclosure is presented and discussed. It is found that the tilt angle strongly affects the fluid flow and heat transfer in the enclosure at the three convective regimes.Keywords: Copper-water nanofluid; Penalty finite element method; Lid-driven triangular enclosure; Tilt angle; Mixed convection.© 2011 JSR Publications.

The total domination number of G is the minimum cardinality of a total dominating set of G. A total dominating set D is said to be a complete cototal dominating set if the induced subgraph has no isolated vertices. The complete cototal domination number of G is the minimum cardinality of a complete cototal dominating set of G.

L'hypothèse de demande induite : un bilan économique
Authors: Rochaix Lise , Jacobzone Stéphane 
Published: September 2011

The Induced Demand Hypothesis: an Economic Assessment by Lise Rochaix and Stéphane Jacobzone
In health economics the induced demand hypothesis is bringing about a transformation in the way health-care demand is perceived. It posits that health-care demand does not simply reflect choice in terms of patient utility but can also be determined by a doctor's implicit motivation. This extremely polemical hypothesis has formed the basis for numerous empirical studies. In this paper we demonstrate that the controversy arises partly from the exact formulation of the hypothesis. A detailed analysis of available work on the extent of induced demand leads to a qualified judgement. On the empirical level, the academic debate seems to be partly closed, although it has not been definitively resolved given the limitations of the tools. Nevertheless, this economic assessment underlines the weight of the incentives to which doctors are exposed in the practice of their profession. This is not without an effect on discussion of payment systems for providers and may shed light on certain economic policy choices.
