A study of comparitive analysis of the outcome of Hardinge’s and Moore’s approach of hemi arthroplasty of hip

Background: The posterior (Moore) approach is generally considered to be easy to perform and has less tissue dissection, which leads to shorter operation times and less blood loss. The lateral (Hardinge) approach can provide generous exposure of the acetabulum, which facilitates cup positioning results may decrease rates of hip dislocation.Methods: In this study a prospective comparative study of outcome of Hardinge’s vs. Moore’s approach in hemi arthroplasty of hip done on 60 consecutive consenting cases who presented with a primary diagnosis of neck of femur fractures. The Selection of patients was randomized by selecting every alternate case of neck of femur fractures by Moore’s approach or Hardinge’s approach. Study recruited 30 cases in each group after the preoperative parameters like age, sex, side, mechanism of injury and the type of fracture.Results: 30 cases underwent hemi - arthroplasty of hip by Hardinge’s approach vs. Moore’s technique and we found that there was difference in duration of hospital stay, the duration of healing and the rate of complications were much higher in the Moore’s technique. In our study there was no mortality. Conclusions: Based on the findings of our study we recommend that between Hardinge’s and Moore’s approach, Hardinge’s approach is recommended as better than Moore’s approach due to number of complications is lower in Hardinge’s

Spectrophotometric Determination of Iron(II) and Cobalt(II) by Direct, Derivative, and Simultaneous Methods Using 2-Hydroxy-1-Naphthaldehyde-p-Hydroxybenzoichydrazone

Optimized and validated spectrophotometric methods have been proposed for the determination of iron and cobalt individually and simultaneously. 2-hydroxy-1-naphthaldehyde-p-hydroxybenzoichydrazone (HNAHBH) reacts with iron(II) and cobalt(II) to form reddish-brown and yellow-coloured [Fe(II)-HNAHBH] and [Co(II)-HNAHBH] complexes, respectively. The maximum absorbance of these complexes was found at 405 nm and 425 nm, respectively. For [Fe(II)-HNAHBH], Beer's law is obeyed over the concentration range of 0.055–1.373 μg mL−1 with a detection limit of 0.095 μg mL−1 and molar absorptivity ɛ, 5.6 × 104 L mol−1 cm−1. [Co(II)-HNAHBH] complex obeys Beer's law in 0.118–3.534 μg mL−1 range with a detection limit of 0.04 μg mL−1 and molar absorptivity, ɛ of 2.3 × 104 L mol−1 cm−1. Highly sensitive and selective first-, second- and third-order derivative methods are described for the determination of iron and cobalt. A simultaneous second-order derivative spectrophotometric method is proposed for the determination of these metals. All the proposed methods are successfully employed in the analysis of various biological, water, and alloy samples for the determination of iron and cobalt content

The effects of rotational flow, viscosity, thickness, and shape on transonic flutter dip phenomena

The transonic flutter dip phenomena on thin airfoils, which are employed for propfan blades, is investigated using an integrated Euler/Navier-Stokes code and a two degrees of freedom typical section structural model. As a part of the code validation, the flutter characteristics of the NACA 64A010 airfoil are also investigated. In addition, the effects of artificial dissipation models, rotational flow, initial conditions, mean angle of attack, viscosity, airfoil thickness and shape on flutter are investigated. The results obtained with a Euler code for the NACA 64A010 airfoil are in reasonable agreement with published results obtained by using transonic small disturbance and Euler codes. The two artificial dissipation models, one based on the local pressure gradient scaled by a common factor and the other based on the local pressure gradient scaled by a spectral radius, predicted the same flutter speeds except in the recovery region for the case studied. The effects of rotational flow, initial conditions, mean angle of attack, and viscosity for the Reynold's number studied seem to be negligible or small on the minima of the flutter dip

The Mundane Female Space: Re-evaluating the Dynamics of Women in the Transnational Kitchen

The kitchen space has often been read as the ultimate arena for women’s manifold repression, discomfiture, and gendered labour. This article aims to evaluate the nature of the kitchen space through the analysis of movies, which give a significant amount of visibility to the kitchen space. The arguments investigated in this article are laid out in two ways: one, to re-assess the stereotypical notions about the mundane space as prevalent in the literature, and two, to problematise the space and understand it from multiple perspectives and dimensions. We consider these two arguments while conducting a textual analysis and thematic network analysis of two movies, Julie and Julia (2009) and The Lunchbox (2013) for such an assessment, because of the many facets of the kitchen space that are underlined in their narratives. We evaluate the twin concepts of emancipation and emasculation visible in kitchen or food work through Abarca’s “culinary epistemology”. The difference between how the three women protagonists “do gender” is another important point that we put into perspective. Zimmerman and West identified “doing gender” as performing work based on the social script. Care work primarily work in the kitchen can therefore be categorised as gendered since it is bound by societal norms. Both the movies deal at large with female protagonists (identified by me as “Gastronome Women”), their interactions with the kitchen space, and the gendered work that does not always tantamount to drudgery that they perform in their respective social positions. The movies also analyse the role of men as willing participants and agencies that help women achieve, instead of throttling their desires. This study also aims to understand the nature of the relationship that women share with the kitchen space and the difference of gendered performance in each of these women. The kitchen space has multiple connotations: this article aims to ameliorate them without dictating a singular, unilinear view
