Published: July 2015

INTRODUCTION We observed that a number of patients presenting to our clinic with diverticular fistulation were taking nicorandil for angna. Recognised side effects of nicorandil include gastrointestinal and genital ulceration. The aim of our study was to determine whether nicorandil is an aetiological agent in diverticular fistulation. PATIENTS AND METHODS We conducted a case-control study of patients with diverticular disease related enteric fistulae. Two patient groups were identified: a study group of patients with diverticular fistulae, and a control group with uncomplicated diverticular disease. The proportion of patients who had ever used nicorandil was compared between the two groups. RESULTS A total of 153 case notes were analysed, 69 patients with fistulae and 84 control patients with uncomplicated diverticular disease. Female to male ratio in both groups was 2:1. The mean age was 71 years in the fistula group and 69 years in the control diverticular disease group (P = ns). Of those with colonic fistulae, 16% were taking nicorandil compared with 2% of the control group (odds ratio 7.8; 95% confidence interval 1.5–39.1; P = 0.008). There was no significant difference in rates of ischaemic heart disease between fistula and control groups. CONCLUSIONS Nicorandil is associated with fistula formation in diverticular disease.

INTRODUCTION Intractable haemorrhage after endoscopic surgery, including transurethral resection of the prostate (TURP) and photoselective vaporisation of the prostate (PVP), is uncommon but a significant and life-threatening problem. The knowledge and technical experience to deal with this complication may not be wide-spread among urologists and trainees. We describe our series of TURPs and PVPs and the incidence of postoperative bleeding requiring intervention. PATIENTS AND METHODS We retrospectively reviewed 437 TURPs and 590 PVPs over 3 years in our institution. We describe the conservative, endoscopic and open prostatic packing techniques used for patients who experienced postoperative bleeding. RESULTS Of 437 TURPs, 19 required endoscopic intervention for postoperative bleeding. Of 590 PVPs, two patients were successfully managed endoscopically for delayed haemorrhage at 7 and 13 days post-surgery, respectively. In one TURP and one PVP patient, endoscopic management was insufficient to control postoperative haemorrhage and open exploration and packing of the prostatic cavity was performed. CONCLUSIONS Significant bleeding after endoscopic prostatic surgery is still a potentially life-threatening complication. Prophylactic measures have been employed to reduce peri-operative bleeding but persistent bleeding post-endoscopic prostatic surgery should be treated promptly to prevent the risk of rapid deterioration. We demonstrated that the technique of open prostate packing may be life-saving.

Published: July 2015

INTRODUCTION Differentiating supination external rotation (SER) type II and IV ankle injuries is challenging in the absence of a medial malleolar fracture or talar shift on radiographs. The accurate differentiation between a stable SER-II from an unstable SER-IV injury would allow implementation of the appropriate management plan from diagnosis. The aim of this study was to ascertain the practice of orthopaedic surgeons in dealing with these injuries. MATERIALS AND METHODS A postal survey was undertaken on 216 orthopaedic consultants from three regions. RESULTS In the presence of medial-sided clinical signs (tenderness, swelling, ecchymosis), 22% of consultants would perform surgical fixation. 53% would choose non-operative treatment and the majority would monitor these fractures through serial radiographs. The remaining 25% of consultants would perform an examination under anaesthesia (EUA; 15%), request stress radiographs (9%) or an MRI scan (1%). Without medial-sided signs, 85% would advocate non-operative treatment and, of these, 74% would perform weekly radiographs. Interestingly, 6% would perform immediate surgical fixation. Stress radiographs (6%) and EUAs (2%) were advocated in the remaining group of consultants. Foot and ankle surgeons utilised stress radiographs more frequently and were more likely to proceed to surgical fixation should talar shift be demonstrated. CONCLUSIONS Clinical practice is varied amongst the orthopaedic community. This may lead to unnecessary surgery in SER-II injuries and delay in diagnosis and operative management of SER-IV injuries. We have highlighted the various investigative modalities available that may be used in conjunction with clinical signs to make a more accurate diagnosis.

Published: July 2015

Introduction The usefulness of thoracic damage control (DC) for trauma requiring a thoracotomy is not established. The aim of this study was to clarify the usefulness of thoracic packing as DC surgery. Methods This was a retrospective case series study of 12 patients with thoracic trauma suffering uncontrollable intrathoracic haemorrhage and shock who underwent intrathoracic packing. Our thoracic DC technique consisted of ligation and packing over the bleeding point or filling gauze in the bleeding spaces as well as packing for the thoracotomy wound. The success rates of intrathoracic haemostasis, changes in the circulation and the volume of discharge from the thoracic tubes were evaluated. Results Packing was undertaken for the thoracic wall in five patients, for the lung in four patients, for the vertebrae in two patients and for the descending thoracic aorta in one patient. Haemostasis was achieved successfully in seven cases. Of these, the volume of discharge from the thoracic tube exceeded 400ml/hr within three hours after packing in three patients, decreased to less than 200ml/hr within seven hours in six patients and decreased to 100ml/hr within eight hours in six patients. Systolic pressure could be maintained over 70mmHg by seven hours after packing. Conclusions Intrathoracic packing is useful for some patients, particularly in the space around the vertebrae, at the lung apex, and between the diaphragm and the thoracic wall. After packing, it is advisable to wait for three hours to see whether vital signs can be maintained and then to wait further to see if the discharge from the thoracic tube decreases to less than 200ml/hr within five hours.

Published: July 2015

Introduction Controversy exists regarding the timing of surgery in children with displaced supracondylar fractures of the humerus. Methods We reviewed retrospectively the postoperative outcomes and complications in these children managed in a district general hospital. Results There were 81 children with displaced supracondylar fractures (64 Gartland type III and 17 type IIA). Of these, 46 children were treated within 6 hours of presentation and 35 were treated later. The rate of open reduction was higher in children treated early (23%) than in late cases (11%). There was no significant difference in the postoperative outcomes and complications between the groups. Conclusions In children with a supracondylar fracture, the timing of surgical treatment (before or after six hours from presentation to hospital) had no effect on postoperative complications and outcomes.

Published: July 2015

Abstract
The study carries out a gender based economic analysis of yam production among resource poor farm households in Kwara State with implication for poverty reduction in the state. One hundred and eighty randomly selected representative farm households were used for the study. Descriptive statistics, budgetary analysis and multiple regression model were the analytical tools. The results of the descriptive statistics show that 85% of the heads of the farm households were male with 66% of the male heads having no western education against 59% for the female-headed households. Labour cost was the major cost of production accounting for 64% and 66% of the total cost of production for the male and female-headed households, respectively. Yam production enterprise was profitable in the study area with net farm income of N136,950 and N128,800 for male and female-headed households, respectively. The return on capital employed was 48% and 45% for male and female-headed households, respectively. This shows that for every naira invested in yam production enterprise in the study area, average returns of 48kobo and 45kobo were obtained for the male and female-headed households, respectively. Farm size, family labour and yam seeds were the significant variables explaining the variation in yam output in the study area. Farm size and labour were under-utilised while yam seeds were over-utilised. The study recommends increased farm size and labour use per hectare and reduction in yam seeds per hectare for efficient resource use and increased net farm income for better living standard for the farm households.
Growing Apart: The Evolution of Income vs. Wealth Inequality
Authors: Cragg Michael , Ghayad Rand 
Published: July 2015

Abstract
The gap between the richest Americans and the rest of the nation has changed dramatically over the past three decades – becoming one of the most challenging political and economic trends for the nation. For decades prior to that, the distribution of wealth and income had been relatively stable, so much that a central problem posed in the economics literature was to explain this stability. But beginning in the early 1980s, inequality began to grow rapidly and has recently been attracting substantial attention from policymakers and researchers reflecting a widespread concern that reflecting a widespread concern that growing labor incomes of senior executives, finance professionals, and successful entrepreneurs is entailing large economic costs to society. The dominant paradigm in the media and Washington is that inequality is purely a matter of divergence in earned (labor) income inequality which can be ameliorated by making earned income taxes more progressive and shifting spending to help the poorer. However, this is not the story: wealth inequality, as it turns out, is much worse. This warrants emphasis for a variety of reasons: (1) a growing body of research that suggests that in the head-on comparison it is wealth inequality, rather than income inequality or poverty that has a negative, statistically significant effect on economic growth.

Bagchi and Svejnar (2013).
(2) Historically societies have failed when wealth has become overly concentrated; and (3) the wedge between earned and unearned income tax rates reduces progressivity as capital income rises. We offer a number of solutions which should generate debate amongst economists as they test conventional wisdom.
Intertheoricity: Plasticity, Elasticity and Hybridity of Theories. Part II: Semiotics of Transferogenesis
Authors: Guillaume Astrid 
Published: July 2015

Abstract
Theories are processes modelled by thought. When they evolve in time, they are transformed and become new theories. They may cross from one academic discipline to another, then open up to new areas of human knowledge, mixing together the humanities, art, science and even spirituality. The way they are modelled reveals their plasticity and their elasticity is tested in their potential for transfer from one field to another, while the different contacts they make and mergers they undergo generate a certain hybridity. Plasticity, elasticity and hybridity are the triad which makes the transfer of theories possible.
The Monastic Hermitage in the End of 19th Century French Literature: a New Identity Space
Authors: Cedergren Mickaëlle 
Published: July 2015

Abstract
Through a comparative reading of three novels of the late nineteenth century, namely Le Disciple, A rebours and Un homme libre, the monastic hermitage has emerged as a common place in which the protagonists of the novels, in search for a spiritual space, let themselves be shaped and transformed by the materiality of places. Through the consideration of the specific features of these closed and sacred sanctuaries, as well as the identity and the dream of the end of the 19th century man, a new literature searching for an ideal will appear openly.
Application of Deep Eutectic Solvent (DES) as a Reaction Media for the Esterification of Acrylic Acid with n-Butanol
Authors: Sert Emine 
Published: July 2015

Abstract
Within the framework of green chemistry, catalysts should be met different criteria such as biodegradability, recyclability, flammability, non-toxicity and low price. Acidic deep eutectic solvent (DES) have been synthesized for this purpose, by mixing para-toluene sulfonic acid and choline chloride. The catalytic activity of DES was studied in the esterification of acrylic acid with n-butanol. The usage of DES as catalyst is simple, safe and cheap. The effects of temperature, catalyst loading, n-butanol/acrylic acid molar ratio on the conversion of acrylic acid were performed. The batch reactor experiments were carried out at temperatures of 338, 348, 358 and 368 K, molar ratio of butanol to acrylic acid of 1, 2,3 and catalyst loading of 10, 15, 20 and 90 g/L. 90.2% of acrylic acid conversion was achieved at a temperature of 358 K and catalyst loading of 20 g/L. Reusability of DES was investigated. Reusability and catalytic activity makes DES efficient as catalyst.

Published: July 2015

Abstract
This paper presents studies concerning the applicability of two clay materials for the construction of a sustainable landfill liner. The studies consisted in determination of basic characteristics of the materials, eg particle size distribution, bulk density, particle density, total porosity, pore size, mineralogy, specific surface area, nanoparticle size, and Atterberg limits, as well as measurements of their geotechnical and hydraulic parameters, such as in situ saturated hydraulic conductivity, modules of primary and secondary compression, cohesion, and angle of internal friction. Furthermore, the effects of compaction performed by the Proctor method at various water contents on swelling and shrinkage characteristics and saturated hydraulic conductivity were investigated in order to determine the compliance with the national requirements for selection of material for landfill liner construction. The determined characteristics and geotechnical parameters of the tested clay materials allowed qualifying them as suitable for municipal landfill construction. The shrinkage potential of the tested clays observed was rated as moderate to very high. The cyclic drying and rewetting of the clay materials performed resulted in a significant increase in saturated hydraulic conductivity. Thus, the clay sealing layers, as part of a multilayer liner, should be very carefully operated, preventing the drying out of the clay sealing and assuring the possibility of its constant saturation.

Published: July 2015

AbstractIn childhood and adolescence, some patients with cerebral palsy (CP) have long-term limited mobility, which can lead to secondary osteoporosis, Prevention and treatment strategies have been evaluated for the management of low bone mineral density (BMD) and fragility fractures. Currently, however, there are no established guidelines for the stratification and individualization of therapeutic interventions. Recently, an increasing number of studies have reported on the use of bisphosphonates to increase BMD in various pediatric conditions, and bisphosphonates have been suggested as a method to treat osteoporosis and prevent fractures.We performed the current meta-analysis to assess the effects of bisphosphonates on increasing BMD in children who have CP with secondary osteoporosis.A search of PubMed, Cochrane, and Embase from inception to April 2014 was performed with the following keywords: (bone disease, metabolic OR osteoporosis OR osteopenia) AND (child OR pediatric OR adolescent) AND (cerebral palsy) AND (bisphosphonate). Four studies were ultimately included in the meta-analysis: one randomized, double-blinded, placebo-controlled study and three case-controlled studies.The Z-score of lumbar spine was significantly improved after bisphosphonates treatment compared with pre-treatment values (standardized mean difference [SMD], 0.799; 95% confidence interval [CI], 0.499–1.100; p<0.001). The Z-score of femur was also improved significantly compared with that of the baseline value (SMD, 0.748; 95% CI, 0.382–1.114; p<0.001).Bisphosphonates have a significant effect on improving BMD in children with CP. Further standardization of treatment protocols including treatment dosage and duration needs to be established, and long-term follow up studies are needed.

Authors: Dommange Xavier , Tanguy Philippe A. , Jolicoeur Mario 
Published: July 2015

AbstractBackground. Mechanical stress was investigated as a mean to harvest microalgal lipids without affecting algal cells’ viability. Monoraphidium minutum was cultivated in laboratory-scale photobioreactors and suspension cultures were submitted to mechanical stress to compare a cyclone, a centrifuge and a homogenizer. Lipid content within the extracellular medium was analyzed prior to and after treatment, and the amount of released lipids was quantified. Algal cell viability was also evaluated before and after treatment.Results. After mechanical-stress treatments, 7.0 to 12.7% of the intracellular lipids of Monoraphidium minutum were released and found in the extracellular medium, while recovered algal cells presented low levels of disruption after treatments.Conclusions. To the best of our knowledge, this is the first proof-of-concept demonstration on the use of mechanical stress for lipid extraction from viable microalgae. Certain level of centrifugation proved to make algae release around 10% of their lipids to the extracellular medium. This mostly exploratory work calls for deeper investigation, paving the way for a biofuel production based on continuous lipid recovery and microalgae reuses.
Effects of centrifugal stress on cell disruption and glycerol leakage from Dunaliella salina
Authors: Xu Y. , Milledge J.J. , Abubakar A. , Swamy R.A.R. , Bailey D. , Harvey P.J. 
Published: July 2015

AbstractDunaliella salina accumulates large amounts of intracellular glycerol in response to the increases in salt concentration, thus is a potential source for producing fuel grade glycerol as an alternative to biodiesel-derived crude glycerol. D. salina lacks a cell wall; therefore the mode of harvesting Dunaliella cells is critical to avoid cell disruption caused by extreme engineering conditions. This study explored cell disruption and glycerol leakage of D. salina under various centrifugal stresses during cell harvesting. Results show a centrifugal g-force lower than 5000 g caused little cell disruption, while a g-force higher than 9000 g led to ~40% loss of the intact cells and glycerol yields from the recovered algal pellets. Theoretical calculations of the centrifugal stresses that could rupture Dunaliella cells were in agreement with the experimental results, indicating optimisation of centrifugation conditions is important for recovering intact cells of D. salina enriched in glycerol.

Published: July 2015

Abstract
Research on selective extraction of copper from solution after bioleaching grounded printed circuit boards (PCBs) using LIX 860N-IC were conducted. The effect of LIX 860N-IC concentration, phase ratio and influence of initial pH value of aqueous phase on the extraction of copper and iron was examined. It was found that the extraction rate of copper increases with the LIX 860N-IC concentration. Best results of Cu extraction (98 %) were achieved with extractant concentration of 5 % and pH 1.9. Higher pH value of aqueous phase (pH=2.4) is conducive to the simultaneous effect of Fe co-extraction.
Die opening-induced microstructure growth in extrusion foaming of thermoplastic sheets
Authors: Gandhi Abhishek , Bhatnagar Naresh 
Published: July 2015

Abstract
In this study, the influence of die opening gap on foam attributes during a microcellular extrusion foaming process was investigated. Lower die openings developed higher pressure drops on the foams, as a result of which greater thermodynamic instability was stimulated and, consequently, higher cell density foams along with enhanced expansion ratios were achieved. Further investigations were performed to study the synergistic influence of altering die opening with critical process parameters, namely, screw rotational speed and die temperature, on the foam expansion ratio and morphological transformations. Higher screw rotational speed induced shear nucleation phenomenon, which further enhanced the foaming process significantly. Also, an optimum die temperature was observed, which developed maximum expansion ratio at the lowest die opening gap. This study intends to enhance the understanding of extrusion foam processing among academia as well as among industries.
The Hard Problem Of Content: Solved (Long Ago)
Authors: Miłkowski Marcin 
Published: July 2015

Abstract
In this paper, I argue that even if the Hard Problem of Content, as identified by Hutto and Myin, is important, it was already solved in naturalized semantics, and satisfactory solutions to the problem do not rely merely on the notion of information as covariance. I point out that Hutto and Myin have double standards for linguistic and mental representation, which leads to a peculiar inconsistency. Were they to apply the same standards to basic and linguistic minds, they would either have to embrace representationalism or turn to semantic nihilism, which is, as I argue, an unstable and unattractive position. Hence, I conclude, their book does not offer an alternative to representationalism. At the same time, it reminds us that representational talk in cognitive science cannot be taken for granted and that information is different from mental representation. Although this claim is not new, Hutto and Myin defend it forcefully and elegantly.
