This paper reports a new simple four-dimensional（4 D） hyperjerk chaotic system. The proposed system has only one stable equilibrium point. Hence, its strange attractor belongs to the category of hidden attractors. The proposed system exhibits various dynamical behaviors including chaotic, periodic, stable nature, and coexistence of various attractors. Numerous theoretical and numerical methods are used for the analyses of this system. The chaotic behavior of the new system is validated using circuit implementation. Further, the synchronization of the proposed systems is shown by designing an adaptive integrator backstepping controller. Numerical simulation validates the synchronization strategy.

Laser-induced breakdown spectroscopy （LIBS） technique has been applied to inves- tigate two different types of bacteria, Escherichia coli （B1） and Micrococcus luteus （B2） deposited on glass slides using Spectrolaser 7000. LIBS spectra were analyzed using spectrolaser software. LIBS spectrum of glass substrate was compared with bacteria spectra. Ca, Mg, Na, K, P, S, C1, Fe, A1, Mn, Cu, C, H and CN-band appeared in bacterial samples in air. Two carbon lines at 193.02 nm, 247.88 nm and one hydrogen line at 656.28 nm with intensity ratios of 1.9, 1.83 and 1.53 appeared in bacterial samples B1 and B2 respectively. Carbon and hydrogen are the important components of the bio-samples like bacteria and other cancer cells. Investigation on LIBS spectra of the samples in He and Ar atmospheres is also presented. Ni lines appeared only in B2 sample in Ar atmosphere. From the present experimental results we are able to show that LIBS technique has a potential in the identification and discrimination of different types of bacteria.

BACKGROUND: Fast track strategy in the management of patients undergoing intra-abdominal surgery of various types has emerged as a landmark approach to reduce surgical stress and accelerate recovery. This study was to evaluate the effect of fast track strategy on patients subjected to pancreaticoduo-denectomy (PD) from an individual unit during transit from low to a high volume center. METHODS: A total of 142 PD patients who had been subjected to fast track strategy between june 2008 and September 2012 were compared with 46 patients who had received convention-al surgery between january 2006 and May 2008. Comparative analysis was made of postoperative complications, postopera-tive recovery, length of hospital stay and patient readmission requirement. RESULTS: The patients subjected to fast track strategy had a faster recovery and a shorter hospital stay than those who were treated conventionally (7.8 vs 12.1 days). The intraoperative events like operative blood loss (417.9±83.8 vs 997.4 ±151.8 mL, P CONCLUSIONS: This preliminary analysis suggests that the fast track approach might be beneifcial to the well-being of the patients after PD, for it accelerates the immediate clinical recovery of patients and signiifcantly shortens their length of hospital stay.

AIM To determine the overall and comparative risk of procedure related perforation of balloon assisted enteroscopy(BAE) in Crohn's disease(CD). METHODS Systematic review(PROSPERO #CRD42015016381) of studies reporting on CD patients undergoing BAE. Seventy-three studies reporting on 1812 patients undergoing 2340 BAEs were included. Primary outcome of interest was the overall and comparative risk of procedure related perforation of diagnostic BAE in CD. Secondary outcomes of interest were risk of procedure related perforation of diagnostic double balloon enteroscopy(DBE), risk of procedure related perforation of therapeutic BAE, efficacy of stricture dilation, and clinical utility of endoscopically assessing small bowel disease *** Per procedure perforation rate of diagnostic BAE in CD was 0.15%(95%CI: 0.05-0.45), which was similar to diagnostic BAE for all indications(0.11%; IRR = 1.41, 95%CI: 0.28-4.50). Per procedure perforation rate of diagnostic DBE in CD was 0.12%(95%CI: 0.03-0.44), which was similar to diagnostic DBE for all indications(0.22%; IRR = 0.54, 95%CI: 0.06-0.24). Per procedure perforation rate of therapeutic BAE in CD was 1.74%(95%CI: 0.85-3.55). Eighty-six percentof therapeutic perforations were secondary to stricture dilation. Dilation was attempted in 207 patients and 30% required surgery during median follow-up of 18 months. When diagnostic BAE assessed small bowel disease activity, changes in medical therapy resulted in endoscopic improvement in 77% of patients. CONCLUSION Diagnostic BAE in CD has a similar rate of perforation as diagnostic BAE for all indications and can be safely performed in assessment of mucosal healing.

In this study, an ecofriendly and economically viable waste management approach have been attempted towards the biosynthesis of agriculturally important nanoparticles from jarosite waste. Aspergillus terreus strain j4 isolated from jarosite（waste from Debari Zinc Smelter,Udaipur, India）, showed good leaching efficiency along with nanoparticles（NPs） formation under ambient conditions. Fourier-transform infrared spectroscopy（FT-IR） and transmission electron microscopy（TEM） confirmed the formation of NPs. Energy dispersive X-ray spectroscopy（EDX analysis） showed strong signals for zinc, iron, calcium and magnesium,with these materials being leached out. TEM analysis and high resolution transmission electron microscopy（HRTEM） showed semi-quasi spherical particles having average size of 10‐50 nm. Thus, a novel biomethodology was developed using fungal cell-free extract for bioleaching and subsequently nanoconversion of the waste materials into nanostructured form. These biosynthesized nanoparticles were tested for their efficacy on seed emergence activity of wheat（Triticum aestivum） seeds and showed enhanced growth at concentration of 20 ppm. These nanomaterials are expected to enhance plant growth properties and being targeted as additives in soil fertility and crop productivity enhancement.
