Opis:
Biomechanical analyses seek to improve understanding of the mechanisms of knee injury and to find ways to reduce knee injury incidence. Many clinical biomechanics researchers use a standard kinematic adopted from Newington Children’s Hospital. Biomechanical studies include the knee joint configurations, where joint architecture immutably constrains and guides movement outcomes. Investigators will default to reporting resultant joint deformation without considering the influence of joint architectural configurations on kinematic responses. The purpose of this study was to develop a new joint angular kinematic method that accounts for influence of dynamic joint architectural configuration on deformation values. Twenty subjects performed unloaded dynamic flexion/ extension and 45° cutting maneuver. The knee deformation angles obtained with the new method proposed were compared with the values that obtained using the standard method. One way repeated measurement ANOVA’s was used to compare knee deformation angles values from the standard method that uses a static trial and the new method that uses a dynamic trial. The proposed method distinguishes between dynamic joint architectural configuration and joint deformation. Loaded standard abduction/adduction (β) and rotation (γ) angles were 3.4 ±1.8° and 11.2 ±3.8°, respectively. Using the new method, the β and γ angles decrease to 1.5 ±1.4° (<0.05) and 7.1 ±1.8° (<0.05) during cutting. The new method accounted for dynamic joint architectural configuration produced loaded β and γ angles that had smaller magnitudes than the standard method, suggesting that previous studies may have overestimated β and γ angles. Injury management strategies could be influenced by a consideration for dynamic joint architectural configuration. Such a consideration could influence ligament repair strategies. Future studies should account for dynamic configuration when establishing the influence of joint deformation on graft design and appropriate isometry values during reconstruction.

Opis:
Aim: The objective of the paper is to construct an index of fiscal performance of Indian states using four non-parametric approaches ( Data Envelopment Analysis(DEA), Free Disposal Hull(FDH), Order-m and Order-alpha).The reason behind using non-parametric methods for the purpose of construction of index is that the traditional ratio approach is incapable of handling multiple input and output indicators.Research methods: The present study uses a two stage approach. In the first stage, four non-parametric methods have been used to evaluate the performance of Indian states for five consecutive years. The input and output indicators have been selected on the basis of a simple theoretical model. Further, in order to tackle the problem of estimation bias (due to sampling variations) bootstrapped DEA and bootstrapped Order-m methods have been applied. In the second stage ,impact of indebtedness on the performance of the states has been assessed using a censored regression framework.Findings: The major outcome of the study is the construction of a fiscal performance index based on multiple indicators. Moreover, the second stage results indicate that state performance is significantly influenced by their degree of indebtedness.Originality/Value of the article: The present study is perhaps the first attempt to assess the performance of sub-national units in terms of both convex and non-convex mathematical programming methods.Implications of the research : The approach (with suitable  modifications) can be effectively used to benchmark state performance which can serve as a basis for resource transfer from the central government to the states.
Cel: Artykuł ma na celu skonstruowanie indeksu kondycji fiskalnej indyjskich stanów w oparciu o metodę DEA. Uzasadnieniem wykorzystania metod nieparametrycznych w celu opracowania indeksu jest niezdolność tradycyjnego podejścia współczynnikowego do uwzględnienia wskaźników wielokrotnych nakładów i wyników. Metodyka badań: Badanie oparto na dwuetapowym podejściu. W pierwszym etapie wykorzystano metodę DEA do oceny kondycji indyjskich stanów w pięciu kolejnych latach. Wskaźniki nakładów i wyników użyte w DEA ostały wybrane na podstawie prostego modelu teoretycznego. Następnie, aby rozwiązać problem błędu szacunkowego (ze względu na wariacje doboru próby), zastosowano samoczynną DEA. W drugim etapie oceniono wpływ zadłużenia na kondycję stanów, wykorzystując cenzurowane modele regresji. Wnioski: The major outcome of the study is the construction of a fiscal performance index based on multiple indicators. Moreover, the second stage results indicate that state performance is significantly influenced by their degree of indebtedness. Wartość artykułu: Głównym wynikiem badań jest opracowanie indeksu kondycji fiskalnej opartym na wielokrotnych wskaźnikach. Co więcej, wyniki z drugiego etapu badań wskazują, że kondycja stanów znajduje się pod istotnym oddziaływaniem stopnia ich zadłużenia. Ograniczenia: Niniejsze badanie to prawdopodobnie pierwsza próba oceny kondycji jednostek subnarodowych pod względem zarówno wypukłych, jak i niewypukłych metod programowania matematycznego. Implikacje: Zaprezentowane podejście (z odpowiednimi modyfikacjami) może być z powodzeniem stosowane do benchmarkingu kondycji stanów, co może służyć jako podstawa transferu zasobów od rządu centralnego do stanów.

Opis:
Indian states exhibit considerable heterogeneity in terms of revenue mobilizing capacities and efforts, development spending and fiscal dependence on the central government. In this context, the paper compares the fiscal performance of major Indian states in terms of two non-parametric performance evaluation models for the period 2009–10 to 2014–15. The study thus uses the conventional two stage framework for efficiency evaluation as well as the two stage conditional performance model. The outcomes enable us to identify front-runners as well as laggards in the area of fiscal management. Further, the study showed that the gross capital formation experienced by the states significantly influences state performance in India. However, the impact of outstanding liabilities on efficiency performance was statistically insignificant

Opis:
A simple mathematical model for the temperature evolution in the cornea exposed to short-pulsed Ho: YAG laser under Laser Thermo Keratoplasty (LTK) treatment is developed by incorporating both the heat flux phase-lag and temperature gradient phase-lag in Fourier’s heat transfer model. An analytical solution to the mathematical model is obtained using the Laplace transformation technique. The computational results for the temperature profile and the temperature variation with time are presented through the graphs. The effect of some typical parameters: the heat flux phase-lag and the temperature gradient phase-lag on the temperature distribution and temperature variations are illustrated and discussed.

Opis:
The north-east sector of the Himalaya is one of the most active tectonic belts, with complex geological and tectonic features. The b-value and spatial correlation dimension (Dc) of earthquake distribution in the north-east Himalaya and its adjacent regions (20–32°N and 88–98°E) are estimated in the present study. Based on seismicity and faulting pattern, the region is divided into five active regions, namely the (i) South-Tibet, (ii) Eastern-Syntaxis, (iii) Himalayan-Frontal Arc, (iv) Arakan-Yoma belt and (v) Shillong-Plateau. A homogeneous catalogue of 1,416 earthquakes (mb ≥ 4.5) has been prepared from a revised catalogue of the ISC (International Seismological Centre). The b-value has been appraised by the maximum likelihood estimation method, while Dc values have been calculated by the correlation integral meth-od; b-values of 1.08 ± 0.09, 1.13 ± 0.05, 0.92 ± 0.05, 1.00 ± 0.03 and 0.98 ± 0.08 have been computed for the South-Tibet, Eastern-Syntaxis, Himalayan-Frontal Arc, Arakan-Yoma belt and Shillong-Plateau region, respectively. The Dc values computed for the respective regions are 1.36 ± 0.02, 1.74 ± 0.04, 1.57 ± 0.01, 1.8 ± 0.01, and 1.83 ± 0.02. These values are > 1.5, except for the South-Tibet (1.36 ± 0.02). The b-values around the global average value (1.0) reflect the stress level and seismic activity of the regions, while high Dc values refer to the heterogeneity of the seismogenic sources.

A survey on the cyanobacterial biodiversity of 7 mangrove environments viz. Vallikunnu, Kadalundi, Kallayi, Mangalavanam, Kumbalam, Kumarakom and Mekkara mangroves of Kerala was undertaken during 2014-2016. In total, 31 species of cyanobacteria coming under 10 genera and 4 families were recorded in all mangrove environments. Maximum species (13 species) of cyanobacteria were recorded from Kadalundi, whereas the minimum was recorded from Mangalavanam (2 species). The genus Oscillatoria was observed with maximum distribution (13 species), followed by Nostoc (5 species) and Lyngbya (3 species). The genus Aphanocapsa, Microcoleus and Scytonema (2 species each) and Chroococcus, Aphanothece, Merismopedia, and Phormidium (1 species each) shows equal distribution. As many as three species, namely Oscillatoria salina, Oscillatoria ornata and Oscillatoria vizagapatensis were common in all mangrove environments except Mangalavanam and Mekkara.

Opis:
The frequent incremental release of software in agile development impacts the overall reliability of the product. In this paper, we propose a generic software reliability model for the agile process, taking permanent and transient faults into consideration. The proposed model is implemented using the NHPP (non-homogenous Poisson process) and the Musa model. The comparison of the two implementations yields an effective, empirical and reliable model for agile software development.

Opis:
Objective: The purpose of this study was to examine the influence of gender and existing, recurrent low back pain (rLBP) on lower extremity and trunk mechanics, as well as neuromuscular control, during a lift task. Design: A multivariate design was used to examine the effects of gender and group on biomechanical and neuromuscular control variables in randomized symmetric and asymmetric lifting. Methods: 68 Males and females with rLBP and healthy performed symmetric and asymmetric weighted box lifting trials to a 1 meter height table. Results: Lifting style was different between gender and between the rLBP versus healthy groups during a 1m box lifting. A significant two-way interaction effect between gender and group was observed for multifidus muscle activity and knee rotation in asymmetric lifting. Several gender and group main effects were observed in pelvis obliquity, trunk flexion and side flexion, knee abduction angles in symmetric lifting; and in pelvis obliquity and rotation, trunk flexion and side flexion, hip abduction, knee abduction angles, external oblique and internal oblique muscles activity in asymmetric lifting. Conclusions: Females and individuals with rLBP appear to use different lifting styles that emphasize movement at the pelvis accompanied by poor kinematic control features at the hip, trunk and knee. Clinicians should be mindful of these changes when developing prevention and rehabilitation programs aimed at improving trunk control in preparation for lifting tasks during domestic and occupational activities.

Opis:
The aim of present work is the development of a quasi-steady state model for the time course concentration profile describing the oxygen diffusion and consumption in a multilayered corneal tissue and investigation of the effect of various model parameters on the oxygen concentration for open and closed eyes. A simple mathematical model for the oxygen transport in multilayered corneal tissue was developed using Fick’s law of diffusion, Michaelis-Menten kinetics of metabolism. A Crank-Nicolson finite difference scheme of the equation describing the oxygen diffusion and consumption was written, in which spatial diffusive terms of the equation were approximated by central differences while the temporal terms were approximated by average of forward and backward time differences. A system of linear equations obtained from the Crank-Nicholson finite differences schemes was solved by the Thomas Algorithm in which successive improve approximate results are obtained.
