Are Per Capita Real GDP Series in African Countries Non-stationary or Non-linear? What does Empirical Evidence Reveal?
This paper extends the applied time series literature in economic development, by testing whether the per capita real GDP time series in 27 African countries are non-stationary or non-linear and globally stationary over the relatively long period from 1960 to 2007. Using the non- linear unit root tests developed recently by Kapetanios, Shin and Snell (2003) the results show that in one-third of the countries, the series are stationary with non-linear mean reversion. Policy implications are indicated.Mean reversion, non-linear unit root tests, GDP per capita
Bony impressions on caput and neck of human femora in Indian Population.
Idiopathic osteoarthritis of the hip has been currently attributed by researchers to the repetitive microtrauma caused to the femoral neck by its impingement against the acetabular rim. This impingement occurs as a result of abnormal morphological traits like Allen’s fossa, Poirier’s Facet, and Posterior Cervical Imprint that appear on the proximal end of femur especially on the neck. Hence, this study was undertaken to investigate the incidence of these traits in the Indian population and to find a correlation between the occurrence of the trait and the side and sex of the bone. The study was conducted on 152 adult dried femora in the Department of Anatomy, Maulana Azad Medical College, New Delhi, India. The positive findings were photographed. The significance of the correlation was found out using Chi-square test. Allen’s Fossa was found to occur in 71.1% of the total bones assessed Poirier’s Facet in 31.6% and Posterior Cervical Imprint in 19.7%. Out of these, a significant side association was found for the Poirier’s Facet with a predominance of the left side. All the traits were found to be more in males with a significant sex variation for Poirier’s Facet. Each trait demonstrated a significant side and gender dimorphism
A rare constellation of multiple upper limb anomalies
We describe an unusual combination of unilateral upper limb variations, including
an axillary arch, absence of a “typical” musculocutaneous nerve, direct
lateral cord innervation of the muscles usually supplied by the musculocutaneous
nerve, variant superficial brachial artery, a high anomalous origin of the
common interosseous artery and a superficial ulnar artery noted during routine
cadaver dissection. The embryological basis, recent molecular insights concerning
such a constellation of anomalies and its clinical relevance are discussed

Long Term Factors of Internet Diffusion in Sub-Saharan Africa: A Panel Co- Integration Analysis
Identifying factors that influence the diffusion of the Internet is paramount for researchers as well as policy makers in articulating strategies to improve the availability and subsequent use of the Internet. Most existing empirical studies have focused on this problem by analyzing diffusion data for countries for one fixed year and identified variables affecting the Internet diffusion. These variables, generally, come from the economic, technological, policy, culture, and human capital realms. These results have provided a good “snapshot” of what factors are important towards the diffusion of the Internet and the results tend to vary for studies conducted in different time frames. This paper also addresses, the phenomenon of cross-country dependence – the economic, political, and technological environment of one country affecting other countries- into account in their analyses. This paper, for the first time in the literature, empirically identifies long-term determinants of the Internet diffusion in sub-Saharan African (SSA) countries by considering data for the period 1997-2013. It employs a recently-developed technique named “panel co-integration analysis” to model the diffusion of the internet among the SSA countries. The analysis reveals that in SSA countries, the number of telephones, the level of per capita real gross product and the extent of ruralization (conversely, the degree of urbanization) are the key long-term drivers of the diffusion of the Internet. Finally, the paper concludes with a discussion of policy implications
An anomalous variation in the innervation pattern of the peroneus longus muscle by deep peroneal nerve: a case report
The muscles of the leg are partitioned into three compartments (anterior, lateral and posterior) which have separate innervations. The peroneus longus muscle is included in the lateral compartment and is innervated by the superficial peroneal nerve. We report an unusual finding in the innervation pattern of the peroneus longus muscle on the right side of a 65 year old female cadaver, in which the branches from the deep peroneal nerve were found to innervate the peroneus longus muscle. This finding is of academic interest and clinical significance to surgeons operating on the proximal fibula for nerve decompression, high tibial osteotomy andnerve transfer operations.Key words: Deep peroneal, common peroneal,nerve, peroneus longus, variations
Nutrients, Nutraceuticals and Bioactive Properties of Multi-Whole Grain Mix for Drink and Porridge
Whole grains are reported to be rich in nutrients, nutraceuticals and have number of health beneficial effects. A convenient multi-whole grain mix for the preparation of a drink or porridge was formulated by using cereals, millets, pulses and nuts. Particle size was mostly of 180-250 microns (52%). Amylograph characteristics like GT, PV, HPV, CPV were 82°C, 285BU, 310BU, and 605BU, respectively were ideal for drink. The mix was found to be rich in carbohydrate, protein, fibre and calorie. The 100g of the mix had nutraceuticals like carotenoids (290µg), γ-tocopherol (4.6mg), α-tocopherol (1.5mg), and polyphenols-soluble, bound and total (94,132 and 226mg GA Eq.). Bioactive properties like vitamin E activity, free radical scavenging activity, total antioxidant activity and starch digestibility were 2.6i.u., 153mg catechin.Eq./100g, 17mg Tocopherol equivalent and 61.8%. Mix was sensorily acceptable in the form of drink and porridge and can be used as an ideal nutritious food for all age group
