Nasopharyngeal Obstruction: A Rare Post Laser Assisted Tonsillectomy Complication  [PDF]
K. P. Morwani, Amol Patil, Gaurav Ahluwalia
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2016, DOI: 10.4236/ijohns.2016.52014
Abstract: Tonsillectomy once was a most common ENT procedure, being referred in past as the “bread and butter of otorhinolaryngologists” though not so commonly performed these days. The usual complications of this procedure have been haemorrhage-primary/reactionary/secondary, infection, tonsillar bed structures injury, and even death. With the advent of newer technologies like lasers, microdebriders, coblators, harmonic scalpel, radiofrequency, newer complications also arise. This case report focuses on one such complication of laser assisted tonsillectomy, not much spoken of in books.
Variation in Wood Properties and Growth in Some Clones of Populus deltoides Bartr. ex Marsh  [PDF]
P. K. Pande
American Journal of Plant Sciences (AJPS) , 2011, DOI: 10.4236/ajps.2011.25076
Abstract: The present paper deals with within ramet radial, intra- and inter-clonal variations in the wood element’s dimensions and specific gravity of 10 clones of Populus deltoides Bartr. ex Marsh. The growth parameters namely ramet height and DBH were also considered for the study. Study material was collected from the 10 clones of Populus deltoids raised by WIMCO Plantations Ltd. at Rudrapur (Udhamsingh Nagar), India. Three clones were parent viz. G48, S7C8 (female) and G3 (male). Other clones represent hybrids of F1 generation. Inter- and intra-clonal variations were significant for all the wood traits except vessel element length for intra-clonal variations. Within ramet variations due to radial location were significant for fiber length and specific gravity with increasing trend from pith to periphery. Interaction of clone*replication was also significant for all the wood traits. Variations were significant for the DBH for the clones. Fiber length and specific gravity was significantly higher in female while wall thickness and vessel element length was in male clones (P < 0.01). Female parents (G48 and S7C8) showed higher fiber length and specific gravity than of the male parent (G3) while vessel element diameter and wall thickness was higher in male parent (G3). Fiber length was higher in offspring than the parent clones which may be the reflection of hybrid vigor for the trait. The clones of F1 offspring followed the similar patterns for the other wood traits as in the parent clones. Hierarchical cluster analysis showed that W/A 39 (male) and W 39 (female) clones of F1 generation were highly divergent than of the other clones.

Abstract: In this article the possibilities of functioning of breast as an attractant to male and leading to a long lasting relation in many cases are discussed. The three mechanisms discussed are on the basis of visual stimuli, pheromone and other chemicals like sebum.
A Note on Kuratowski’s Theorem and Its Related Topics  [PDF]
K. P. Shum
Advances in Pure Mathematics (APM) , 2017, DOI: 10.4236/apm.2017.78025
Abstract:
In point set topology, it is well known that the Kuratowski 14-set problem is one of the most interesting results. In this note, we first give a brief survey of the Kuratowski’s theorem. In particular, we will study and investigate the structure of the boundary of a given subset in a topological space. Some new results and topics which are related to the theorem of Kuratowski are presented and discussed. Finally, we pose some open problems of Kuratowskitype.
The “Kiel Knots” Technique for Treatment of Congenital and Acquired Penile Deviation  [PDF]
Daniar K. Osmonov, K. P. Jünemann
Advances in Sexual Medicine (ASM) , 2013, DOI: 10.4236/asm.2013.31004
Abstract:

Objectives: We propose a surgical correction of the penile curvature applying a technique based on the 16-dot plication technique modified by burying the knots in a shallow trough of incised tunica. We entitle this modification the “Kiel Knots”. Material and methods: 20 patients with a penile deviation, average age 36.8 years (24 - 52) were operated. Follow-up time was 26 months. In 8 patients the deviation was congenital, in 12 patients it was an acquired deviation. The deviation was >30? in all patients. Surgical technique: A circumcising incision was made and the penis was degloved. Buck’s fascia was incised exposing the tunica albuginea opposite the curvature. 8 dots were marked bilaterally on the tunica albugineaand a5 mmincision along the marks was made without cutting into the Corpus cavernosum. Instead of plicating with one suture for 4 dots, our modification uses one suture for two dots with the knot buried in a shallow trough created by a scalpel. Results: The average operation time was 64 minutes. We observed a loss of penile length in 30% of the patients (0.5 - 1 cm). There were no problems with erectile function. In a follow-up of 2 years, 90% of the patients remained without recurrence of deviation. None of patients reported problems with the suture knots. Conclusion: Our technique achieves penile straightening with minimal loss of length and no erectile dysfunction.

Sono-Photo Fenton Treatment of Liquid Waste Containing Ethylenediaminetetraacetic Acid (EDTA)  [PDF]
S. Chitra, K. Paramasivan, P. K. Sinha
International Journal of Nonferrous Metallurgy (IJNM) , 2013, DOI: 10.4236/ijnm.2013.22012
Abstract:

Ethylenediaminetetraacetic acid (EDTA) is a chelating agent that has been used for decontamination purposes in nuclear industry. The presence of EDTA in decontamination wastes can cause complexation of the cations resulting into interferences in their removal by various treatment processes such as chemical precipitation, ion exchange etc. Further, it might also impart elevated leachability of cationic contaminants from the conditioned wastes immobilized in cement or other matrices and can negatively influence the quality of the final form of waste. In the present study, kinetics of degradation of EDTA (20,000 mg/l) by employing either Photo-Fenton process using UV (15 W λmax = 253.7 nm) or Sono-Fenton process using ultrasound at 130 KHz or simultaneous Sono-Photo Fenton process has been investigated. EDTA is effectively degraded by the synergistic effect of both Photo Fenton and Sono Fenton process. All the above mentioned processes were found to follow a first order kinetics reaction. From the observed pH changes during the oxidation processes, it can be concluded that there is a loss of chelating ability of EDTA. Formation of amides was con- firmed during the degradation processes.

Pressure Transient Analysis of an Intersecting Rollover Faulted Crest Boundary in Niger Delta Oil Field  [PDF]
K. K. Ihekoronye, I. P. Nwosu
Open Journal of Yangtze Oil and Gas (OJOGas) , 2019, DOI: 10.4236/ojogas.2019.42010
Abstract: Pressure transient analysis has been extensively applied to detect anomalies in a reservoir system. These anomalies may be presented in the form of an intersection of the crestal and the antithetic fault associated with a growth fault. Interpretation of this fault can only be achieved through the use of pressure transient analysis. The objective of the research work is to analyze and test the faulted crest, depth of the anticline structure and examine the near well bore conditions in order to evaluate whether the well productivity is governed by wellbore effects (skin effects + well bore effect) or the reservoir at large. A case study of a well in the Niger delta is considered with a series of build up test carried out in two intervals of both upper and lower gauge readings. In this study, a computer aided design which uses a pressure derivative approach is used in this work to match the pressure derivative of an intersecting fault (angle) model to the field data, and the model assumes the characteristics of the reservoir. Based on the result of the interpreted data, simulation is done by using a non linear regression method (least square). The simulated data interpreted are achieved through the regression coefficient which provides a quantitative measure of the agreement between field data and the model. In conclusion, the best cases are taken from all the results and a nodal analysis is performed to diagnose the inflow performance of the well through the transient analysis in order to optimize the recovery of the oilfield.
Enrichment of Cobalt Values by Dry Magnetic Separation from Low-Grade Manganese Ores of Bonai-Keonjhar Belt, Orissa  [PDF]
P. P. Mishra, B. K. Mohapatra, P. P. Singh
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2009, DOI: 10.4236/jmmce.2009.84028
Abstract: Resource potential of cobalt in India is practically negligible. Cobalt in marine manganese nodule though known since long, its report from terrestrial manganese ore is least observed. This paper reports the occurrence of cobalt in low-grade manganese ores of Bonai-Keonjhar belt, Orissa, eastern India and describes methods for its possible enrichment. Cobalt is associated with manganese minerals like lithiophorite (~CoO: 1.2%) and cryptomelane (~CoO: 0.2%). A feed of low-grade siliceous manganese ore containing 26% Mn and 32% SiO2 and 0.08% Co was subjected to physical beneficiation. By processing the low-grade siliceous ore on a dry belt magnetic separator, a product with 47% Mn at 60% recovery could be obtained. It was observed that along with manganese the cobalt value gets enriched (~Co: 0.38%) more than four times in comparison to the feed. Some other traces like Ni, Cu, Zn, Ga, Li etc. also get enriched in the magnetic product. Thus, through simple dry magnetic separation a low-valued material cannot only be converted to usable product but two valuable metals can also be recovered from it.

P.P. Mishra, B.K. Mohapatra, K. Mahanta
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2009, DOI: 10.4236/jmmce.2009.81005
Abstract: The low-grade siliceous manganese ores from Bonai-Keonjhar belt, Orissa, India was mineralogically characterized and investigated for their possible upgradation. Different physical beneficiation techniques like gravity, magnetic separation etc. were employed and results reported. The results reveal that a feed having 26% Mn could be upgraded to more than 45% Mn by using a dry belt type magnetic separator with 69% recovery at 1.00 tesla magnetic intensity at finer sizes.
Finding the Efficient Frontier for a Mixed Integer Portfolio Choice Problem Using a Multiobjective Algorithm  [PDF]
K. P. ANAGNOSTOPOULOS, G. MAMANIS
iBusiness (IB) , 2009, DOI: 10.4236/ib.2009.12013
Abstract: We propose a computational procedure to find the efficient frontier for the standard Markowitz mean-variance model with discrete variables. The integer constraints limit on the one hand the portfolio to contain a predetermined number of assets and, on the other hand, the proportion of the portfolio held in a given asset. We adapt the multiobjective algorithm NSGA for solving the problem. The algorithm ranks the solutions of each generation in layers based on Pareto non-domination. We have applied the procedure in sixty assets of ATHEX. We have also compared the algorithm with a single genetic algorithm. The computational results indicate that the procedure is promising for this class of problems.
