Pinar Ergenoglu,Cagla Bali,Sule Akin,Nesrin Bozdogan Ozyilkan
Cukurova Medical Journal , 2013,
Abstract: Purpose:Renal transplantation significantly improves quality of life compared to hemodialysis in patients with end-stage renal failure. In end-stage renal failure anesthetic technique should be planned carefully, due to changes in volume distribution, drug metabolism, excretion. Results of total intravenous anesthesia, inhalation anesthesia, regional techniques are being investigated. Aim of this study was to present our experience in total intravenous anesthesia in 77 patients, who underwent live and cadaveric donor renal transplantation at Baskent University Faculty of Medicine Adana Teaching and Research Center. Material and Methods:Induction of anesthesia was performed with propofol(2mg/kg) and fentanyl(1μg/kg), and rocuronium bromide(0.4-0.5mg/kg) was given before intubation. Anesthesia was maintained with total intravenous anesthesia(propofol,50 mcg/kg/min; remifentanil,0.25 mcg/kg/min infusion). Intraoperative fluid, urine volumes were recorded. For preemptive multimodal analgesia, pre-incisional intravenous paracetamol(15mg/kg), intramuscular morphine(0.1mg/kg) were given. Postoperative analgesia was maintained with intravenous patient-controlled analgesia(meperidine 10 mg bolus, with a lockout time of 20 minutes). Postoperative pain was recorded using Visual Analogue Scale, level of sedation was assessed by Ramsey Sedation Scale. Results:Study included 64(83.1%) live donor transplantations and 13(16.9%) cadaveric donor transplantations. Mean total fluid administration was similar between live and cadaveric donor kidney transplantation patients however mean intraoperative urine output was significantly higher in live donor kidney transplantation patients(p<0.001). 57.1% of patients had no pain at 5. minutes postoperatively(Visual Analog Scale Score=0), at 15. minutes postoperatively mean visual analog scale score was 2.6 and the first analgesic requirements were recorded at 39.6 minutes. According to Ramsey Sedation Scale, majority of patients(54.5%) had response to commands at postoperative 5th minutes and 85.7% of patients were completely cooperative-oriented after 30 minutes. None of patients had deep sedation or respiratory depression. Conclusion:Total intravenous anesthesia can be considered as a safe method in patients with renal transplantation, may contribute to early postoperative recovery and transfer to the transplantation unit.

Anesthesia Management of an Emergent Caesarean Section Case with the History of Central Core Myopathy: Case Report
Cagla Bali,Pinar Ergenoglu,Sule Akin,Anis Aribogan
Cukurova Medical Journal , 2013,
Abstract: Central core myopatyhy is a rarely seen hereditary neuromuscular disorder that is involved in congenitally myopathies group. The disease is characterized by muscular weakness, skeleton system deformities, increased malign hyperthermia sensitivity and anesthesia management is critically important. In these patients, prolonged muscular weakness and malign hyperthermia that can complicate the perioperative management are the most critical risks. In this case report, anesthesia management of an electively planned caesarean section patient, taken into emergency surgery that is also previously known to have central core myopathy diagnosis will be shared.

Reduction of Undercuts in Fillet Welded Joints Using Taguchi Optimization Method  [PDF]
Joseph Achebo, Sule Salisu
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2015, DOI: 10.4236/jmmce.2015.33020
Abstract: This project work focuses on the reduction of weld undercuts using the Taguchi method. The phenomenon of weld undercuts constitutes a major problem for the welding industry. When undercuts occur, and particularly when such cuts are deep, it has a negative impact on the weld as it lowers the integrity and quality of the weldment. Therefore, efforts are made globally to reduce the depth of such weld undercuts to the barest minimum. Several optimization methods have been adopted; however, in this study, the Taguchi method is applied. “The smaller the better components” of the Taguchi method is applied. From the results obtained from applying this Taguchi method, the optimum process parameters obtained are A2-B1-C2, which are a voltage of 20 V, a current of 180 A, and a welding speed of 130 mm/s, required to form an undercut of 0.03 mm. Whereas the existing process parameters used by the company are A1-B3-C, which make an undercut to a depth of 0.09 mm. It is concluded that the use of Taguchi method has been able to reduce the depth of undercut as shown in this study. A step-by-step approach is presented in the study.

Technology and Investment (TI) , 2010, DOI: 10.4236/ti.2010.14031
Abstract: Using a cross-section of Nasdaq-listed Israeli companies, we examine the impact of R & D spending on their market values and the ecosystem for start-ups in Israel. We find a very strong positive association between the two, learning that $1 million of spending in R & D associated with an increase of $5 million of market value. Among all countries outside the U.S., Israel is third after Canada and China in terms of the number of stocks registered on Nasdaq. Since 1981, sixty-one companies have registered, and their total R & D spending in 2009 reached $3.750 billion, which is approximately equal to the total R & D expenditure of Turkey. In the region, Middle Eastern and North African (MENA) countries cannot accomplish to register in Nasdaq. Israel’s great success comes from the strong dedication and cooperation between private and public sectors in research and venture capital. Israel spends 4.7% of its GDP for R & D, which is equal to the total expenditure of MENA.
Does Venture Capital Spur Patenting? Evidence from State-Level Cross-Sectional Data for the United States  [PDF]
Mustafa Seref Akin
Technology and Investment (TI) , 2011, DOI: 10.4236/ti.2011.24030
Abstract: We test the venture capital and patenting hypothesis state-level cross-section data for the United States, whereas previous research has been industry and firm based. We categorize R&D funds (federal research, industry research and academic research funds). We include the income level (gdp per capita) and size of the states (gdp, population, civilian labor force). We consider human capital factors as adding science and research holders of each state through different categories (doctoral sciences and engineering degree holders, graduate students of science and engineering, post doctorate students). Finally, we include the grants received by the Small Business Innovation Center. Even after controlling so many variables, our results suggest that venture funding has a strong positive impact on patenting in state-level cross-section data. A one billion dollar increase in venture capital is associated with an increase in 440 patents whereas a one billion dollar increase in corporate R&D is associated with an increase in 140 patents. Kortum and Lerener [1] find that a dollar of venture capital is seven times more powerful in stimulating pattern than a dollar of corporate R&D. Our research suggests that this difference is three times.

The method of this research is survey method. The location of the research was conducted on Kelompok Tani that was targeted by the UPSUS of Increasing Production of Paddy, Corn and Soybeans in 2017. Research Objects are Farmers who become group leaders and group members who are members of farmer groups who receive assistance UPSUS program to Increasing Production Rice, Corn and Soybean. The results showed that the direct effect of leadership variables on member satisfaction has a significance value greater than 0.05 (0.210), which means no significant effect. The results showed that the direct effect of leadership variables on member satisfaction has a significance value greater than 0.05 (0.210), which means no significant effect. While the standardized value of beta coefficient on t test shows that the magnitude of direct influence of leadership on member satisfaction is equal to 0.115 or rounded to 11%. That is, the high level of member satisfaction can only be influenced by the leadership of 11% while the rest (89%) influenced by other factors outside the model.
Perturbation Theory on Top of Optimized Effective Potential Method
P. Sule
Physics , 1999,
Abstract: We present a perturbative approach within the scope of Kohn-Sham density functional theory (DFT). The method is based on the exact exchange-only optimized effective potential method, and correlation is included via perturbation expansion using Rayleigh-Schrodinger (RS) perturbation theory (PT). The correlation potential is constructed from Moller-Plesset formulation of RS calculations. This naturally leads to a new iterative scheme when finite order perturbation theory is employed. The new iterative procedure can be taken as a self-consistent parameter-free DFT PT, and, as such, provides correlation energy which is explicitly functional of the self-consistent orbitals, eigenvalues and also of the exchange-correlation potential.
Generalization of Boole-Shannon expansion, consistency of Boolean equations and elimination by orthonormal expansion
Virendra Sule
Computer Science , 2013,
Abstract: The well known Boole-Shannon expansion of Boolean functions in several variables (with co-efficients in a Boolean algebra $B$) is also known in more general form in terms of expansion in a set $\Phi$ of orthonormal functions. However, unlike the one variable step of this expansion an analogous elimination theorem and consistency is not well known. This article proves such an elimination theorem for a special class of Boolean functions denoted $B(\Phi)$. When the orthonormal set $\Phi$ is of polynomial size in number $n$ of variables, the consistency of a Boolean equation $f=0$ can be determined in polynomial number of $B$-operations. A characterization of $B(\Phi)$ is also shown and an elimination based procedure for computing consistency of Boolean equations is proposed.
An algorithm for Boolean satisfiability based on generalized orthonormal expansion
Virendra Sule
Computer Science , 2014,
Abstract: This paper proposes an algorithm for deciding consistency of systems of Boolean equations in several variables with co-efficients in the two element Boolean algebra $B_{0}=\{0,1\}$ and find all satisfying assignments. The algorithm is based on the application of a well known generalized Boole-Shannon orthonormal (ON) expansion of Boolean functions. A necessary and sufficient consistency condition for a special class of functions was developed in \cite{sule} using such an expansion. Paper \cite{sule} develops a condition for consistency of the equation $f(X)=0$ for the special classes of Boolean functions 1) $f$ in $B(\Phi(X))$ for an ON set $\Phi$ of Boolean functions in $X$ over a general Boolean algebra $B$ and 2) $f$ in $B(X_{2})(\Phi(X_{1}))$. The present paper addresses the problem of obtaining the consistency conditions for arbitrary Boolean functions in $B_{0}(X)$. Next, the consistency for a single equation is shown equivalent to another system of Boolean equations which involves the ON functions and characterizes all solutions. This result is then extended for Boolean systems in several variables over the algebra $B_{0}=\{0,1\}$ which does not convert the system into a single equation. This condition leads to the algorithm for computing all solutions of the Boolean system without using analogous resolution and determine satisfiability. For special systems defined by CNF formulas this algorithm results into an extension of the DPLL algorithm in which the \emph{splitting rule} is generalized to several variables in terms of ON terms in the sense that splitting of CNF set in a single variable $x$ is equivalent to ON terms $x,x'$.
Anti-Hypertensive Prescription and Cost Patterns in an Outpatient Department of a Teaching Hospital in Lagos State Nigeria  [PDF]
Akin Osibogun, Tochi Joy Okwor
Open Journal of Preventive Medicine (OJPM) , 2014, DOI: 10.4236/ojpm.2014.44021
Abstract:

Introduction: Hypertension is a public health problem with a high prevalence in Nigeria. The cost of prescription medications is thought to be a barrier for many patients to access the healthcare they need. This study was aimed at identifying associated co-morbid conditions, the prescribing patterns and cost of prescription for the treatment of hypertension in an outpatient clinic at Lagos University Teaching Hospital. Materials and Methods: A cross sectional study was carried out. A total of 147 prescriptions were obtained from the case notes of patients treated at the LUTH outpatient department between February 2012 and August 2012. For each prescription, the number of drugs, the class and combinations of antihypertensives were recorded. The monthly cost of a 30-day anti-hypertensive supply based on the recommended daily dose was calculated. Results: The mean age of the patients was 54(+/-14) years and of the 147 prescriptions, 77(52.4%) was for females and 70(47.6%) was for males. The mean systolic blood pressure was 141.6 mmHg (+/-20.5SD) and mean diastolic blood pressure was 86.5 mmHg (+/-13.3SD). Of the 147 prescriptions, 112(76.2%) were for patients with co-morbidities. The frequency of prescription of the various classes of anti hypertensives are; diuretics 117(79.6%), angiotensin receptor blockers 78(53.1%), angiotensin converting enzyme inhibitors 65(44.2%), calcium channel blockers 65 (44.2%) beta blockers 54(36.7%) and centrally acting agents 12(8.2%). Average cost per month was =N=6611.47 (US$44). There was a statistically significant association between co morbid conditions and high cost of prescriptions with 73.7% of those with diabetes and 63.2% of those with renal disease having cost of prescriptions within the high cost group (p < 0.05). Conclusion: The cost per month is high and it is recommended that hypertension should be addressed as part of an integrated care program. Ingenious ways of health care financing also have to be promoted.
