Open Journal of Orthopedics (OJO) , 2014, DOI: 10.4236/ojo.2014.48033
Abstract: Introduction: Amputation is the removal of a body part through a bone, while disarticulation is a removal of a part through a joint. This common procedure has different causes depending on the geographical locations and cultural practices. These ranges from dead body part to malignancy. Our study focused on the profile of the amputees including the biodata, causes and the financial consequences of the procedure. Material and Methods: The case notes of all patients who had amputation from 1998-2012 (15 years) were collected and the biodata, intra-operative diagnosis, parts amputated and duration of hospital stay were retrospectively analysed. Results: One hundred and ninety six patients had various types of amputations for the duration of our study. 159 (81.12%) were males while 37 (18.88%) were females. 68 (34.69%) patients had below knee amputation. 54 (27.55%) had above knee amputation. 27 (13.78%) had above elbow amputation. 18 (9.18%) patients had below elbow amputation, while 30 (15.30%) patients had other forms of amputations. The highest number of amputees (72 patients) was within the age range of 21 - 30 yr and the least number (5 patients) was within the age range of 51 - 60 yr. The highest number of amputation (71 patients) was due to complications from by traditional bone setters intervention. Conclusion: In our study, we found that most cases were males with a mean age of 35 years and majority (34.69%) had below knee amputation, and that most cases suffered vascular occlusion leading to gangrene.

Open Journal of Statistics (OJS) , 2012, DOI: 10.4236/ojs.2012.21012
Abstract: Raintree (Samanea saman) is a multipurpose village tree species grown in abundance at southern and northern regions of Bangladesh. Village people need to know estimation procedure for timber inventory of this useful tree species. Data on diameter at breast height (diameter) and total height (height) of 205 standing sample trees were collected by Spiegel relascope for the purpose. The sample trees with diameter ranging 21 cm - 91 cm and height ranging 10 m - 20 m were considered for measurement. Volumes (m3) of individual trees were computed by Smalian formula. A total of 10 linear models of volume on diameter and volume (V) on diameter (D) and height (H) were examined with the sample trees. A few statistics of F, t, mean square error, multiple correlation coefficient and Furnivall Index was computed and tested for investigation of best fitted models. The two models of In(V) = 8.3023 + 2.1746 In(D) and In(V) = –9.1864 + 1.85502 In(D) + 0.8234 In(H) were found to be best fitted models. They have been recommended to estimate volume of large scale standing Raintree trees.

International Journal of Conservation Science , 2013,
Abstract: The present study was conducted to estimate the status of common leopard (Panthera pardus) in and around Machiara National Park (MNP) Azad Jammu and Kashmir between May 2007 and July 2008. Fifteen fixed transects were monitored on regular basis. Indirect signs of leopard such as pugmarks and scats were recorded along the transects in addition to people and livestock which were counted as an index of disturbance and mean encounter rate for leopard scats, footprints, livestock and people was calculated. Mean encounter rate for leopard pugmarks was 1.6, for scats 2.11, for livestock 25.03, and for people 22.48. Linear measurements of front and hind pugmarks and strides were classified which indicated that at least six to nine (06-09) individuals are present in the study area (13,532 ha). Questionnaire survey revealed that Leopards were sighted by the locals at 23 locations during the study period including; in the morning (35%), evening (29%), night (21%) and daytime (15%). Maximum sightings were recorded between 4765ft to 9634ft elevation presenting moist temperate zone with Pinus wallichiana as a dominant tree species. As a result of increasing biotic pressures, the leopard has become rare with growing threat of further degradation and fragmentation of its habitat. It may cause the species to depend more on the domestic livestock available in and around the area giving way to the problem of human-leopard conflict. The information generated from the study will be helpful for the conservation and management of this critically endangered species.

Case Reports in Clinical Medicine (CRCM) , 2014, DOI: 10.4236/crcm.2014.31008
Abstract:


Congenital radial club hand (CRCH) is a terminal deficiency characterized by the radial deviation of the hand, marked shortening of the forearm, and generalized underdevelopment of the extremity with an incidence rate of 1 per 100,000 live births. Both sexes are nearly or equally affected. Challenges that the disease poses to the patient are multifaceted, ranging from medical, social, cosmetic and functional issues which also are the multidimensional treatment modalities. We report a case of a 2-month-old baby with the severe case of bilateral CRCH. The patient had the centralization of the left ulna with Kwire stabilization. About 160d of correction was achieved. He did well and was discharged after two weeks at the orthopedic clinic for follow-up. Congenital radial club hand though uncommon may be amenable to surgery. Centralization is still the treatment of choice in severe cases and early intervention will offer a better outcome.

Open Journal of Applied Sciences (OJAppS) , 2014, DOI: 10.4236/ojapps.2014.41003
Abstract: Novel polymeric pigments were synthesized in xylene by cross linked epoxy resin with 1,4 and 1,5-diaminoanthraquinones, by varying weight fractions from 5% to 20% of the diaminoanthraquinone derivatives. FTIR, UV and solubility tests were carried out. The pigments were then used to colour PLA, PMMA, PE and also in emulsion paints using polyvinyl alcohol as binder. Their light fastness, surface drying time and surface hardening time were assessed. It was found that λmax of the 1,4-diaminoanthraquinone shifted towards longer wavelength after the cross linkage, in contrast to the 1,5-diaminoanthraquinone which suffered a blue shift. However in all the cases, the λmax was not affected by the weight fractions of the anthraquinones, but the absorptivity coefficients was significantly increased as the weight fractions of the anthraquinones increased. The light fastness properties of the coloured plastics varied from 4 to 7, indicating a trend of increase with the weight fractions of the anthraquinones. Similar observations were seen with the emulsion paints produced. In all the cases, the 1,4-diaminoanthraqunione produced better result.

Asian Journal of Information Technology , 2012,
Abstract: Nowadays, a major challenge in communication is to send maximum possible information through minimum Band Width. Orthogonal Frequency Division Multiplexing (OFDM) has opened an era for both wired and wireless communication to enhance spectral efficiency to a maximum extent. Time variance of wireless channels destroys the orthogonality among subchannels in Orthogonal Frequency Division Multiplexing (OFDM) system and causes Inter Channel Interference (ICI), which result in an error floor. In this paper, we study Partial Response Coding(PRC) for reducing the effect of the Inter Channel Interference (ICI). Based on the general expression of the ICI power for OFDM with PRC, the optimum weight for PRC that minimize the ICI power has derived. Numerical and simulation result shows that use of more tap have the ability to reduce ICI.
Effects of Syllable Language Model on Distinctive Phonetic Features (DPFs) based Phoneme Recognition Performance
Mohammad Nurul Huda,Manoj Banik,Ghulam Muhammad,Mashud Kabir
Journal of Multimedia , 2010, DOI: 10.4304/jmm.5.6.543-550
Abstract: This paper presents a distinctive phonetic features (DPFs) based phoneme recognition method by incorporating syllable language models (LMs). The method comprises three stages. The first stage extracts three DPF vectors of 15 dimensions each from local features (LFs) of an input speech signal using three multilayer neural networks (MLNs). The second stage incorporates an Inhibition/Enhancement (In/En) network to obtain more categorical DPF movement and decorrelates the DPF vectors using the Gram-Schmidt orthogonalization procedure. Then, the third stage embeds acoustic models (AMs) and LMs of syllable-based subwords to output more precise phoneme strings. From the experiments, it is observed that the proposed method provides a higher phoneme correct rate as well as a tremendous improvement of phoneme accuracy. Moreover, it shows higher phoneme recognition performance at fewer mixture components in hidden Markov models (HMMs).

Journal of Geographic Information System (JGIS) , 2017, DOI: 10.4236/jgis.2017.92007
Abstract: Past studies on the adoption of integrated pest management (IPM), analyzed the significance of non-spatial factors (social, economic, institutional and management factors etc.) in influencing farmers’ decision to adopt IPM while the present study analyzed spatial factors in addition to these non-spatial factors to address the questions-i. Do the spatial factors significantly influence the farmers to adopt IPM? If yes, then to what extent they do affect IPM adoption? The data were collected from 331 vegetable farmers of Narsingdi district, Bangladesh, by conducting a household survey. Farmers’ nineteen characteristics under five broad groups, namely social, economic, institutional, management and spatial factors were analyzed. The result of the binary logistic regression model revealed that two spatial factors namely the distance of farmers’ house from the nearest market and the distance from agriculture office, along with some specific social, economic, institutional and management factors, significantly influenced the farmers’ to use IPM. It is also observed from the model that the role of spatial factors was important in influencing IPM adoption. However, with regard to the level of importance, their contribution was less than those of economic and institutional factors but more than those of social and management factors. The influences of these factors in practicing IPM are discussed individually as well as group based. The findings show significance in domestic policy making.

Chemistry Central Journal , 2012, DOI: 10.1186/1752-153x-6-149
Abstract: Growth rate, biomass productivity and oil content of each algal species have been investigated under autotrophic condition. Biodiesel was produced from algal oil by acid catalyzed transesterification reaction and resulting fatty acid methyl esters (FAMEs) content was analyzed by GC/MS. Fatty acid profiling of the biodiesel, obtained from various microalgal oils showed high content of C-16:0, C-18:0, cis-Δ9C-18:1, cis-Δ11C-18:1 (except Scenedesmus quadricauda) and 10-hydroxyoctadecanoic (except Scenedesmus acuminatus). Absolute amount of C-14:0, C-16:0 and C-18:0 by a validated GC-MS/MS method were found to be 1.5-1.7, 15.0-42.5 and 4.2-18.4 mg/g, respectively, in biodiesel obtained from various microalgal oils. Biodiesel was also characterized in terms of cetane number, kinematic viscosity, density and higher heating value and compared with the standard values.Six microalgae of local origin were screened for biodiesel production. A method for absolute quantification of three important saturated fatty acid methyl esters (C-14, C-16 and C-18) by gas chromatography-tandem mass spectrometry (GC-MS/MS), using multiple reactions monitoring (MRM) mode, was employed for the identification and quantification of biodiesels obtained from various microalgal oils. The results suggested that locally found microalgae can be sustainably harvested for the production of biodiesel. This offers the tremendous economic opportunity for an energy-deficient nation.Fossil fuel is now widely recognized as unsustainable resource with depleting supplies and increasing cost. Moreover, accumulation of carbon dioxide due to fossil fuels in the environment is getting higher. Therefore, renewable fuels are necessary for environmental and economic sustainability [1-3].Biodiesel, as an alternative fuel, has attracted major interest worldwide in recent years. Conventional sources of biodiesel include plant oils and animal fats. The energy content, cetane number and viscosity of biodiesel are similar t

Abstract: Time domain analysis of electromagnetic wave propagation is required for design and characterization of many optical and microwave devices. The FDTD method is one of the most widely used time domain methods for analysing electromagnetic scattering and radiation problems. However, due to the use of the Finite Difference grid, this method suffers from higher numerical dispersion and inaccurate discretisation due to staircasing at slanted and curve edges. The Finite Element (FE)-based meshing technique can discretize the computational domain offering a better approximation even when using a small number of elements. Some of the FE-based approaches have considered either an implicit solution, higher order elements, the solution of a large matrix or matrix lumping, all of which require more time and memory to solve the same problem or reduce the accuracy. This paper presents a new FE-based method which uses a perforated mesh system to solve Maxwell's equations with linear elements. The perforated mesh reduces the requirement on memory and computational time to less than half of that compared to other FE-based methods. This paper also shows a very large improvement in the numerical dispersion over the FDTD method when the proposed method is used with an equilateral triangular mesh.
