Authors: Rinaldi Julia Chen , Hench James , Darnell M. Zachary , Kukurugya Matthew , Rittschof Daniel 
Published: November 2019

In their ranges on east and south coasts of the Americas as well as their established invasions in the Adriatic and Baltic, blue crabs, Callinectis sapidus, inhabit estuaries, sounds and coastal oceans and are commercially and ecologically important. How crabs move in response to physical variables is important to management. We monitored life stages at canal control structures, assessed gender ratios with recreational crabbing, learned from crabbers, and studied movements of tagged crabs in a canal connecting Lake Mattamuskeet to the Pamlico sound. Juveniles enter the lake through two of 4 canals connecting to the sounds. Females migrate out through one canal. The lake standing population is about 70% male. Movements of 240 crabs in August 2012 and 102 crabs in October 2014 were quantified using RFID tags with co-located meteorological and oceanographic devices. Non-spawning females and males are nomadic. Crabs released in the canal move in response to changes in water depth and go with the flow, toward the Pamlico Sound (summer 76% and fall 78%). What crabbers describe as a fall migration appears to be concentration of crabs in warmer deeper canals and then southern movement with flow generated by strong north winds. To be effective, management strategies like migratory corridors require understanding of crab movements.

Published: November 2019

Objective: The aim in this study was to investigate preoperative coagulation
values of patients undergoing oral surgery under local anesthesia.Material and Method: The study included 1598 patients who presented to
the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry at
Adıyaman University between 2017 and 2018 for various reasons and underwent
surgery under local anesthesia based on examination. The patients’ age and
gender as well as their coagulation values such as activated partial
thromboplastin time (APTT), prothrombin time (PT) and international normalized
ratio (INR) were recorded and analyzed statistically.Results: The age range of the patients included in the study ranged between 11 and
92, and their mean age was 30.51 ± 11.09. Of these patients, 63.06% (n = 1007)
were female, and 36.94% (n = 591) were male. The total number of female
patients admitted was more than that of the male patients in terms of the
distribution by gender. When the number of patients admitted were examined in
terms of age groups (0–20, 21–40, 41–60, &gt; 60), statistically significant
differences were found especially between the ages 0–20 and 21–40 in both
gender (p &lt;0.05). No significant differences were found in groups over the
age of 40 (p &gt; 0.05). Values outside the normal range were observed in all
of the coagulation values examined. Among these, APTT and PT (%) values that
were lower than the normal and INR and PT (s) values that were higher than the
normal were found to prevail. An examination of these abnormal values in terms
of gender revealed that the values other than PT (%) were found to be statistically
significantly higher in women, compared to men. In terms of age groups, these
abnormal values belonging to the four coagulation parameters were found to be
statistically significantly the highest among the people who were 21–40 years
old (p &lt; 0.001).Conclusion: Taking preoperative coagulation tests prior to locally applied
surgical procedures is especially important in patients for whom detailed
medical history cannot be obtained.

The eruption of Timor in 1638: 350 years of plagiarism, embellishments and misunderstandings
Authors: Blong Russell James 
Published: November 2019

In 1665 Athanasius Kircher included a short paragraph in his Mundus Subterraneus about a flamy spire and the collapse and disappearance of a high mountain following a ‘horrible earthquake’ on Timor in 1638. Although Timor has been known to have no volcanoes for at least the last one hundred years, Kircher’s story has been repeated for 350 years, generally without acknowledgement, and often with the addition of embellishments and/or errors. This report traces the various accounts and the ways in which the story has morphed, particularly in the early 19th century, when the emphasis in Kircher’s story changes from a ‘flamy spire’, a ‘horrible earthquake’, and the collapse of the volcano into a continuing Stromboli-like eruption with no mention of an earthquake. Strangely, the fiction that the flamy spire could be seen from a distance of 300 miles is maintained and other embellishments added up to the present day.

A infraestrutura das rodovias brasileiras, em termos nacionais, sempre foi um dos maiores gargalos ao crescimento do país. Em relação a outras nações com extensão territorial semelhante, o Brasil apresenta-se como sendo um dos países mais deficientes em infraestrutura e logística, como também ausente de investimentos mais vultosos direcionados ao setor. A partir da análise de dados fornecidos pelas concessionárias das rodovias, os quais confrontados com dados governamentais e relatórios emitidos pela CNT (Confederação Nacional dos Transportes) pôde-se dimensionar a problemática para traçar um estudo comparativo das medidas adotadas pelo governo do Brasil na tentativa de solucionar um dos maiores problemas para o crescimento econômico nacional, denominado: infraestrutura rodoviária, haja vista que a grande maioria dos meios de transporte utilizados para deslocamento e entrega de cargas fazem uso dessa modalidade. Assim, com essa comparação feita através de dados, tabelas e relatórios, as políticas adotadas pelo governo do Estado de São Paulo, que através da concessão apresentava a maior parte da sua malha rodoviária, veio a externar melhores condições no seu sistema viário e uma maior adequação desse, consequentemente sua infraestrutura apresentou maiores qualificações do que as adotadas pelo governo federal nas rodovias públicas.

Authors: Khan Muhammad Naeem , Bibi Niaz , Irum  , Idrees Muhammad 
Published: November 2019

Abstract
A simple, fast and interference free spectrofluorimetric method was developed for the quantification of ciprofloxacin in its pure form, pharmaceutical preparations and in human plasma. The method is based on the enhancement of the weak fluorescence signal of drugs by the addition of sodium dodecyl sulphate (SDS) surfactant micelles in citrate buffer at pH 5.5. Different experimental parameters like buffers, surfactant type and concentration were investigated. The fluorescence intensity of ciprofloxacin was measured at 446 nm (emission) and at 328 nm (excitation). A linear relationship between concentration of ciprofloxacin and fluorescence intensity was found in the range of 0.04 μg/mL–6.0 μg/mL with a correlation coefficient of 0.9946. The limit of detection (LOD) and limit of quantification (LOQ) were calculated and found to be 3.87 × 10−5 and 1.29 × 10−4 μg/mL respectively. The effect of common excipients and co-administered drugs were also investigated and the method was found free of interferences. The method was successfully applied for the determination of ciprofloxacin in pharmaceutical preparations and human plasma with percentage recoveries of 97.08 % to 99.32 % and 95.00 % to 101.25 % respectively.

Abstract
The current requirement for science and research concerns the absolute sustainable development of a chemistry that is inherently safer, smarter and more environmentally friendly. The oxidation reaction is a very fundamental transformation reaction in organic synthesis and likely plays a significant role in the production of various value-added chemicals from biomass and others precursors. In the focus of making kinetic experiments greener several modified methodologies and safe chemicals have been employed. Surfactants are such suitable alternate that go with the requirments. Surfactant aggregates i. e. micelles are nano-sized supra molecules, able to act as catalysts. They can be used to catalyze the organic functional group transformation reactions mediated with transition metals and promoted with various aromatic bases. This allowed water to be used as a solvent, where the reactions became more sustainable. The recyclability of used surfactants, enhancement of reaction kinetics and speed of reaction with no consumption of energy has added more value to this type of catalytic oxidation. This article aims to contribute to the discussion of the mechanistic aspects of various types of surfactant-catalyzed oxidation of organic functional groups.

Abstract
Magnetic carbon nanocomposite (MCNC) was prepared from peanut shells and then characterized by FTIR, SEM, TGA/DTA and BET surface area. The removal of cetyltrimethyl ammonium bromide (CTAB) surfactant from aqueous solution was carried out by MCNC and membrane. The effect of contact time, initial concentration of CTAB and the temperature on the adsorption of CTAB was also investigated. Initially, the adsorption of CTAB on MCNC was rapid up to 20 min and then gradually slowed down. Different kinetic models i. e. 2nd pseudo order kinetics, power function and intraparticle diffusion were applied to determine different kinetic parameters. Intraparticle diffusion model showed that the adsorption of CTAB is a diffusion controlled process. Thermodynamic parameters i. e. ΔH° (–33.74 kJ/mol), ΔS° (0.98 J/mol K) and ΔG° (–62.91 kJ/mol, −64.37 kJ/mol and −66.33 kJ/mol) were calculated and the process was found to be exothermic and spontaneous in nature. The prepared adsorbent (MCNC) was used for controlling fouling of ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) membranes caused by CTAB. Improved permeate fluxes and percent retention of CTAB were observed for MCNC crossbreed membrane. About 100 % retention with no effect on permeate flux was observed with RO membrane when MCNC pretreatment was applied.

Published: November 2019

Purpose: In Canada, approximately 45% of hospitalized patients are moderately or severely malnourished upon admission. The protected mealtime policy was designed to address malnutrition in institutions. This pilot study aimed to provide preliminary results examining the effect of this policy on patient energy and protein intake. Methods: A 1-group, pre–post observation design was conducted in a Canadian hospital. Pre- and post-observations included the frequency and type of interruptions, type of interrupter, and patient energy and protein intake at each meal. Results: The average number and length of interruptions decreased, and the average length of mealtime assistance provided to patients (n = 12) increased in the post-observation period. Energy and protein consumption showed a slight increase during the post-observation period. Conclusion: A protected mealtime policy may be an effective policy to address malnutrition among hospitalized Canadian adults. Further studies are warranted in Canada to determine the effects and feasibility of this policy implementation.

The use of Chebyshev's polynomials of the first type to the strength of materials is based on probabilistic logic for the objective states of a metal. This is the case when "pure" science helps practical issues of objective reality. Due to this, it was noted that the metal undergoes a stable and unstable state during loading. The use of Chebyshev's polynomials of the first type has showed that the most stable state of the metal is shown by the Т9curve, at which the ratio б/бт = 0,5. This ratio is most favorable for pressure vessels, in contrast to the recommended American standard ASME, in which б/бт = 0,666 (this ratio reduces the reliability). Assessment of the state of the metal taking into account the frequency characteristics is more promising. This assessment confirms the frequency ratio б/бт ≈ 0,5 and allows taking into account inelastic phenomena in the metal, taking into account the loss coefficient, as well as to assess the possibility of resonance. The application of the control valve using the patent RU 2416751C1 allows achieving the optimal frequency of gas oscillations in the pipe and reducing the probability of resonance.

Published: November 2019

The creation of a sealed support, providing reliable isolation of layers from each other, is one of the most important tasks in the construction of oil and gas wells. The article presents the most common in recent years in our country and abroad special technological and technical measures used to improve the quality of isolation of oil and gas reservoirs at the stage of cementing and waiting on cement with different gradients of reservoir pressures. Attention is drawn to technical and technological solutions for preventing admission of formation fluids in the annular space of the well during cementing and waiting on cement. The solution to this problem is based on creating the design pressure at the wellhead in the annulus at a rate proportional to the rate of reduction of the hydrostatic pressure column of cement slurry (drilling mud) due to the structure hardening cement slurry.
