Effect of Manganese Content on the Fabrication of Porous Anodic Alumina

The influence of manganese content on the formation of well-ordered porous anodic alumina was studied. Porous anodic alumina has been produced on aluminium substrate of different manganese content by single-step anodizing at 50 V in 0.3 M oxalic acid at 15°C for 60 minutes. The well-ordered pore and cell structure was revealed by subjecting the porous anodic alumina to oxide dissolution treatment in a mixture of chromic acid and phosphoric acid. It was found that the manganese content above 1 wt% impaired the regularity of the cell and pore structure significantly, which can be attributed to the presence of secondary phases in the starting material with manganese content above 1 wt%. The pore diameter and interpore distance decreased with the addition of manganese into the substrates. The time variation of current density and the thickness of porous anodic alumina also decreased as a function of the manganese content in the substrates

Healthy lifestyle interventions in general practice: Part 15: Lifestyle and lower back pain

Lower back pain (LBP) is one of the most common medical problems in the adult population. LBP can be defined as pain, muscle tension or stiffness that is localised below the costal margin (inferior rib cage) and above the inferior gluteal folds and that can present either with or without leg pain (sciatica), and it can be classified as “specific” or “non-specific”. LBP has a high lifetime prevalence and is associated with a substantial direct and indirect cost to the individual and society. In this review, the focus is on the identification of lifestyle risk factors and interventions that are associated with mainly non-specific chronic LBP. In addition to pharmacotherapy, the best treatment approach is exercise therapy (including physical reconditioning), psychosocial and behavioural intervention and therapeutic education. Other lifestyle changes include nutritional intervention and smoking cessation

Healthy lifestyle interventions in general practice: Part16: Lifestyle and fibromyalgia

Fibromyalgia is a chronic disorder, characterised by chronic widespread musculoskeletal pain, and the presence of multiple tender points as well as a host of associated symptomatology. Optimal management of patients with fibromyalgia requires a multidisciplinary approach, with a combination of pharmacological and non-pharmacological interventions that are tailored to the patient's pain, dysfunction and associated features, including depression, sleep disorder and fatigue. Non-pharmacological lifestyle-based interventions to treat this disorder include exercise therapy, dietary modification, and psychosocial interventions. This review outlines these three forms of lifestyle intervention in patients with fibromyalgia

Healthy lifestyle interventions in general practice. Part 2: Lifestyle and cardiovascular disease

This article forms the second part of the series on the role of lifestyle modification in general practice with specific reference to chronic cardiovascular disease. Whilst the major risk factors which constitute an unhealthy lifestyle were discussed in part 1 of this series, the focus of part 2 will give specific practical guidelines which the general practitioner may incorporate into their practice when counselling patients with chronic cardiovascular disease

Adiabaticity Conditions for Volatility Smile in Black-Scholes Pricing Model

Our derivation of the distribution function for future returns is based on the risk neutral approach which gives a functional dependence for the European call (put) option price, C(K), given the strike price, K, and the distribution function of the returns. We derive this distribution function using for C(K) a Black-Scholes (BS) expression with volatility in the form of a volatility smile. We show that this approach based on a volatility smile leads to relative minima for the distribution function ("bad" probabilities) never observed in real data and, in the worst cases, negative probabilities. We show that these undesirable effects can be eliminated by requiring "adiabatic" conditions on the volatility smile

Healthy lifestyle interventions in general practice Part 4: Lifestyle and diabetes mellitus

Diabetes mellitus, in particular Type 2 diabetes, can be classified as a chronic disease of lifestyle. A lifestyle intervention programme is therefore an essential component of the primary and secondary prevention (management) of diabetes mellitus. The main indication for referral to a lifestyle intervention programme is any patient with either pre-diabetes or established diabetes mellitus. Following a comprehensive initial assessment, patients are recommended to attend either a group-based programme (medically supervised or medically directed, depending on the severity of the disease and the presence of any co-morbidities) or a home-based intervention programme. The main elements of the intervention programme are nutritional intervention, exercise training (minimum of 150 minutes at moderate intensity per week), psychosocial support and education. Regular monitoring should be conducted during training sessions, and a follow-up assessment is indicated after 2–3 months to assess progress and to re-set goals. Longer-term (5–6 months) intervention programmes are associated with better long-term outcomes
