African Woman Sexuality: Assessment after Hysterectomy for Uterine Benign Disorders Based on Two Scales; PISQ 12/DFSI  [PDF]
Koffi Abdoul, E. Kacou Aka, M. Fanny, A. Cauphy, N. Olou, J. M. Konan, A. Horo
Open Journal of Obstetrics and Gynecology (OJOG) , 2018, DOI: 10.4236/ojog.2018.813146
Abstract: Background: Several authors are studying sexual activity of hysterectomies women. However, the review of literature reveals few data in sub-Saharan Africa on the psychological and sexual impact of this treatment option. Objective: To assess sexual activity and sexual satisfaction of women after hysterectomy for benign disorders. Methods: Single center analytical study based on patient opinion. It was conducted in a five-year period: from January 2012 to December 2016 at the Yopougon teaching Hospital. Results: Hysterectomy accounted for 15.9% of gynecological surgical activities. Hysterectomy for benign pathology accounted for 3.3% of hysterectomies. The average age was 47.6 years old. The indications were dominated by uterine fibroid (88.68%). Hysterectomy was performed by the abdominal route in 86.79% of cases. Sexual activity was resumed in the second trimester post-operative in 69.81%. After hysterectomy, dyspareunia was reduced (p < 0.05), orgasm was more intense (p < 0.05) with a greater sexual satisfaction (p < 0.05). Conclusion: This study shows that there is no significant difference for women’s sexuality before and after hysterectomy.

Open Journal of Obstetrics and Gynecology (OJOG) , 2017, DOI: 10.4236/ojog.2017.711112
Abstract: Objectives: To describe our management strategy of ovulation disorders. Patients and methods: From a retrospective collection of data from the records, we identified over a period of one year (January 2016-December 2016), 47 patients followed in gynecology department of University and Hospital Centers of Yopougon and Treichville in Abidjan (Cote dIvoire) for ovulation disorders. The diagnosis of dysovulation was made following a hormonal check up and a follicular monitoring ultrasound. These patients underwent a specific treatment according to the type of dysovulation they presented. Results: The average age was 31.9 years with a significant proportion of nulliparous (66%). Body mass index was high in 44.7% of patients, of whom 19.1% were obese and 25.6% overweight. The hormonal balance was disrupted in 48.9% of cases. Polycystic ovary syndrome (WHO type IIb dysovulation) was the most common pathology (36%). The proposed treatments were dominated by clomiphene citrate (31.9%) and gonadotrophins (25.5%). 14.9% of pregnancies were obtained. Conclusion: This study allows us to offer better management of ovulation disorders, but this necessarily entails a careful exploration and an appropriate treatment.
Implementation of a Higher Quality dc Power Converter  [PDF]
N. N. Barsoum
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2010, DOI: 10.4236/jemaa.2010.22012
Abstract: Many single and three-phase converters are well developed, and covered up in most of electric markets. It is used in many applications in power systems and machine drives. However, an exact definite output signal from the dc side still not recognized. The waveforms of output voltage and current demonstrate an imperfect dc signal and constitute losses, harmonic distortion, low power factor, and observed some ripples. An approximately perfect rectifier bridge is the aim of this research. Perhaps it gives the ability to identify the parameters of the converter to obtain, as much as possible, a perfect dc signal with less ripple, high power factor and high efficiency. Design is implemented by simulation on Power Simulator PSIM, and practically, a series regulator LM723 is applied to provide regulating output voltage. Comparisons of both simulation and hardware results are made to observe differences and similarities.

N. Pankratova, N. Nedashkovskaya
Intelligent Control and Automation (ICA) , 2013, DOI: 10.4236/ica.2013.41011

The paper provides mathematical analysis of sensitivity of different combination rules in the DS/AHP method when an alternative is added to the set of decision alternatives while solving foresight problems. Different cases of rank reversals are defined and two sets of conditions for these cases using the method DS/AHP are considered. Rank reversals are illustrated when the DS/AHP method is used to solve practical problem of critical technologies of energy conservation and power efficiency evaluation in Ukraine. It is shown that the DS/AHP method is not sensitive to exclusion (or addition) of an irrelevant decision alternative from (or to) the set of decision alternatives.

The Study of the Secrets of the Genetic Code  [PDF]
N. N Kozlov
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.67007
Abstract: The disclosure of many secrets of the genetic code was facilitated by the fact that it was carried out on the basis of mathematical analysis of experimental data: the diversity of genes, their structures and genetic codes. New properties of the genetic code are presented and its most important integral characteristics are established. Two groups of such characteristics were distinguished. The first group refers to the integral characteristics for the areas of DNA, where genes are broken down in pairs and all 5 cases of overlap, allowed by the structure of DNA, were investigated. The second group of characteristics refers to the most extended areas of DNA in which there is no genetic overlap. The interrelation of the established integral characteristics in these groups is shown. As a result, a number of previously unknown effects were discovered. It was possible to establish two functions in which all the over-understood codons in mitochondrial genetic codes (human and other organizations) participate, as well as a significant difference in the integral characteristics of such codes compared to the standard code. Other properties of the structure of the genetic code following from the obtained results are also established. The obtained results allowed us to set and solve one of the new breakthrough problems—the calculation of the genetic code. The full version of the solution to this problem was published in this journal in August 2017.

N. ?. Orudzheva
American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.312213
Abstract: The results of the long-term investigations in dynamics for study of the conditions of taxonomic groups of microorganisms of irrigated gleyey-yellow soils of the subtropical zone under vegetable crops in rotation with the continuous growing of these cultures have been presented. The results of the researches study demonstrated an important vibration of the microorganisms quantity under growing cultures happens. The most quantity of microorganisms, consuming organic nitrogen is observed in irrigative gleyey-yellow soils of the humid subtropical zone. Intensity of mineralization of organic matters was lower in irrigative gleyey-yellow soils. A quantity of microorganisms was lower, but a coefficient of mineralization was higher under continuous cultures as compared the analogous soils under crop rotation. These data show that a type of the soil influence on the rhizosphere microflora insignificantly, while plant shows a significant effect on its quantity and compositions.
Wavelet-Based Density Estimation in Presence of Additive Noise under Various Dependence Structures  [PDF]
N. Hosseinioun
Advances in Pure Mathematics (APM) , 2016, DOI: 10.4236/apm.2016.61002
Abstract: We study the following model: \"\". The aim is to estimate the distribution of X when only \"\"?are observed. In the classical model, the distribution of \"\"?is assumed to be known, and this is often considered as an important drawback of this simple model. Indeed, in most practical applications, the distribution of the errors cannot be perfectly known. In this paper, the author will construct wavelet estimators and analyze their asymptotic mean integrated squared error for additive noise models under certain dependent conditions, the strong mixing case, the β-mixing case and the ρ-mixing case. Under mild conditions on the family of wavelets, the estimator is shown to be \"\"-consistent and fast rates of convergence have been established.

N. Taub
Open Journal of Depression (OJD) , 2019, DOI: 10.4236/ojd.2019.81001
Abstract: Background: Scopolamine and naltrexone are FDA approved medications that have been utilized off label for the indication of major depressive disorder (MDD). We examined the efficacy of the 2 medications in combination for major depression. Methods: 14 adults (7 female and 7 males) with current major depressive disorder were randomized by coin flip to 0.15 mg BID of scopolamine and 1 mg BID naltrexone or placebo for a total of 4 weeks. Modified MDRS questionnaires were utilized to monitor progress in depression symptomatology. The placebo patients were crossed over to the active medications subsequent to the 4 week trial period. Results: 2 subjects dropped out of the trial as a result of side effects. A total of 12 subjects completed the trial. The average reduction in Modified MDRS scores over the 4 weeks for the active medications was 12.5. The average reduction noted in control patients was 3.5. This difference was statistically significant with P = 0.03, less than 0.05 for a greater than 95% confidence interval utilizing Student’s T test analysis. Of the 4 patients that crossed over to the active medications three additional patients noted a partial or complete response to the medications with an average reduction and Modified MDRS scores of 8. No washout periods were utilized before the trial or for the crossover period. Conclusion: The combination of scopolamine and naltrexone demonstrated significant benefit for MDD.

Journal of Biophysical Chemistry (JBPC) , 2014, DOI: 10.4236/jbpc.2014.54017
Abstract: We investigated the balance of free radicals in different tissues (liver, heart, brain and muscle) of rats in course of in vivo and in vitro processing by Macrovipera lebetina obtusa (MLO) and Montivipera raddei (MR) snake venoms. Chemiluminescence (ChL) levels were examined in tissue assays after incubation (at 37 °C for a period of 10 min) with venom for in vitro experiments and in tissue assays isolated of 10 min after venom injection for in vivo experiments. The TBA-test was also performed to confirm the free radical expression. The activities of antioxidant enzymes (such as superoxide dismutase and glutathione peroxidase) in isolated tissues were detected by spectro-photometry. During the in vitro processing chemiluminescence levels of tissue homogenates significantly decreased, while in course of in vivo intoxication the level of ChL was elevated in brain and liver; lipid peroxidation also increased in brain tissue, but there was no significant balance change in other tissues; the activity of superoxide dismutase mainly correlated with changes of free radical balance during intoxication. On the contrary, the activity of glutathione peroxidase showed the reverse tendencies to change. We suggest that free radicals and their oxidative stresses may play a role in the early stage of intoxication causing the so-named “spreading-effect”, which is very characteristic for the venom of vipers.
