OBJECTIVES： To trace the critical practicing, clinical and epidemiological risk factors in bacterial load and points of intervention in spread of community-acquired methicillin resistant Staphylococcus aureus （CA-MRSA） in healthy community. STUDY DESIGN： 2872 individuals with no prominent clinical features were enrolled and administered a pre-tested questionnaire prepared on the basis of outcome of a prior pilot study in same region. Swab samples from skin, throat and nasal nares were tested for MRSA and molecular identification was done to track the strains moving from hospital to community. METHODS： Swab samples from skin, throat and nasal nares were tested for MRSA culture followed by molecular characterization of isolates and antimicrobial resistance pattern. Bacterial load was estimated to better understand the burden in different categories. Statistical analysis was done using SPSS 16.0 version. RESULTS： History of prior infection （OR 3.9, 95% CI 1.363 - 5.793）, habit of self remedy （OR 3.2, 95% CI 0.991 1.473） and incomplete treatment （OR 0.26, 95% CI 0.08 - 0.80）（P 〈 0.05 for each） were the predominant factors that contributed to spread of CA-MRSA. Increased drug resistance in CA-MRSA was observed for 4 different clones： SCCmec^＋ IVa/PVL^＋, SCCmec^＋ IVa/PVL^- and SCCmec^＋ IVc/PVL^＋, SCCmec^＋ IVc/PVL . Bacterial load was found significantly high in below poverty line dwellers and drug abusers （P 〈 0.05）. CONCLUSION： We identified habit of self remedy, drug abusing and incomplete treatment as practicing risk factors where interventions can be made to manage the dissemination of CA-MRSA in rural population.

Community and hospital acquired methicillin resistant Staphylococcus aureus efficiently retain the Van A determinant

Dissemination of vancomycin resistance from hospital to community strains is a serious threat to public health. Our study aimed to provide evidence for transmission of Van A type resistance from the hospital to the community. Wild-type community and hospital associated methicillin resistant Staphylococcus aureus strains were studied in vitro and in a model that mimicked a natural environment to ascertain their ability to acquire and maintain the vancomycin resistance determinant （Van A gene） from vancomycin resistant Enterococcus faecalis. Fitness was assessed and the cost of Van A acquisition and retention was estimated. In vitro mating experiments were carried out using a filter mating technique and a model of a natural water body environment. Transfer of resistance was carried out in two different conditions： restricted and favorable. Transconjugants were confirmed by E test and PCR using specific primer sets. Growth kinetics and fitness measurements were done by spectrometric analysis. Using the in vitro filter mating technique, high transfer frequencies that ranged from 0.7 × 10^-3（0.0006） to 3.1 ×10^-4（0.00011） were recorded, with the highest transfer frequencies for CA MRSA （thermosensitively homogenous）（0.7 × 10^- 3）, and 1.2 × 10^-4 to 2.4 × 10^-4 in the model. HA MRSA （homogenous） showed a greater capacity （3.6 ×10^-4） to receive the Van A gene, while CA MRSA showed a reduced ability to maintain the gene after serial subcultures. CA and HA thermosensitively heterogeneous MRSA transconjugants exhibited higher growth rates. The present study provides evidence for the enhanced ability of CA and HA MRSA clones to acquire and maintain Van A type resistance.

Numerical analysis of surface subsidence in asymmetric parallel highway tunnels

Journal of Rock Mechanics and Geotechnical Engineering 2017年第1期9卷 170-179页

Tunnelling related hazards are very common in the Himalayan terrain and a number of such instances have been reported. Several twin tunnels are being planned for transportation purposes which will require good understanding for prediction of tunnel deformation and surface settlement during the engineering life of the structure. The deformational behaviour, design of sequential excavation and support of any jointed rock mass are challenging during underground construction. We have raised several commonly assumed issues while performing stability analysis of underground opening at shallow depth. For this purpose, Kainchi-mod Nerchowck twin tunnels(Himachal Pradesh, India) are taken for in-depth analysis of the stability of two asymmetric tunnels to address the influence of topography, twin tunnel dimension and geometry. The host rock encountered during excavation is composed mainly of moderately to highly jointed grey sandstone, maroon sandstone and siltstones. In contrast to equidimensional tunnels where the maximum subsidence is observed vertically above the centreline of the tunnel, the result from the present study shows shifting of the maximum subsidence away from the tunnel centreline. The maximum subsidence of 0.99 mm is observed at 4.54 m left to the escape tunnel centreline whereas the maximum subsidence of 3.14 mm is observed at 8.89 m right to the main tunnel centreline. This shifting clearly indicates the influence of undulating topography and inequidimensional noncircular tunnel.

Control of rock joint parameters on deformation of tunnel opening

Journal of Rock Mechanics and Geotechnical Engineering 2016年第4期8卷 489-498页

In this paper, stress behavior of shallow tunnels under simultaneous non-uniform surface traction and symmetric gravity loading was studied using a direct boundary element method（BEM）. The existing fullplane elastostatic fundamental solutions to displacement and stress fields were used and implemented in a developed algorithm. The cross-section of the tunnel was considered in circular, square, and horseshoe shapes and the lateral coefficient of the domain was assumed as unit quantity. Double-node procedure of the BEM was applied at the corners to improve the model including sudden traction changes. The results showed that the method used was a powerful tool for modeling underground openings under various external as well as internal loads. Eccentric loads significantly influenced the stress pattern of the surrounding tunnel. The achievements can be practically used in completing and modifying regulations for stability investigation of shallow tunnels.

A Coal Mine Dump Stability Analysis—A Case Study

引用

Geomaterials 2011年第1期1卷 1-13页

作者： as.utos. kainthola Dhananjai Verma S. S. Gupte T. N. Singh 不详

The present paper mainly deals with a case study of failed dump slope in western coalfield limited, Nagpur, India. A huge mass of debris flow had happened during the routine the activity of mining. The failed dump had a height of 75 m with 43? slope angle which had slipped forward by 18m. Representative loose dump material samples were collected from the site and tested to determine the physico-mechanical properties of dump material. The dump material consisted of loose fragments and lumps of friable sandstone, shale, clay and carbonaceous shale. To evaluate the condition of failure, a well known, shear strength reduction tech-nique has been applied to achieve the desired factor of safety using two dimensional finite element code. Fi-nally, a economical, sustainable and stable dump angle and height has been suggested for smooth and safe disposal of the dump.

Distinct Element Modelling of Mahabaleshwar Road Cut Hill Slope

Geomaterials 2012年第4期2卷 105-113页

Reliable estimates of slope stability are essential for safe design and planning of road cut hill slopes which accommo-date a number of tourist destinations around the world. The failure of cut slopes along these hills puts human life in grave danger and it is also disastrous for the economy. In the present study, a section of 100 m high jointed basalt hill slope has been analyzed numerically in a distinct element code, which is apt for simulating the behavior for jointed rock. The analysis was carried out for both the dry and saturated conditions. The distinct element analysis of the hill slope demonstrates it to be marginally stable under dry condition, while for the saturated condition, the hill slope fails along well defined joint planes.
