Paederia foetida L. is an important medicinal plant that has been used for the treatment of various gastrointestinal related ailments by different tribal commu- nities in India. This plant is also known for its use as a food. Due to overexploitation, P. foetida has been classified as a vulnerable plant in some states of India. The propagation of P. foetida by conventional methods is easy but very slow. Synthetic seed technology offers incredible potential for in vitro propagation of threatened and commercially valuable plants, and can also facilitate the storage and exchange of axenic plant material between laboratories. However, synthetic seed production for P. foetida has not yet been reported. Thus, to the best of our knowledge, the present study is the first attempt to produce synthetic seeds of P. foetida by calcium alginate encapsulation of in vitro regenerated axenic nodal segments. Sodium alginate (3%) and CaCl2 (100 mM) were found to be the optimal materials for the preparation of ideal synthetic seeds, both in terms of morphology and germination ability. The synthetic seeds showed the best germination (formation of both shoot as well as root; 83.3%) on ½ MS medium augmented with 0.5 mg/L indole-3-acetic acid. The plantlets obtained from these synthetic seeds could be successfully acclimatized under field conditions. We also studied the storage of these synthetic seeds at low tem- perature and their subsequent sprouting/germination. The seeds showed a germination rate of 63.3% even after 21 days of storage at 4 °C; thus, they could be useful for transfer and exchange of P. foetida germplasm.
Solvent Effects on the Electronic Spectra of Some Heterocyclic Azo Dyes
Behera, Pradipta Kumar,Xess, Anita,Sahu, Sachita Korean Chemical Society 2014 Bulletin of the Korean Chemical Society Vol.35 No.2
The influence of solvent polarity on the absorption spectra of some synthesized azo dye with heterocyclic moieties and ${\beta}$-naphthol (1-3) have been investigated using a UV-Visible spectrophotometer. The spectral characteristics of the azo dyes (1-3) in different solvents at room temperature were analyzed. The solvatochromic empirical variables like ${\pi}^*$, ${\alpha}$, and ${\beta}$ have been used to discuss the solvatochromic behaviour of the dyes and to evaluate their contributions to the solute-solvent interactions. A multi-parameter regression model for quantitative assessment of the solute/solvent interaction and the absorption has been used to explain the solvent effect on azo dyes (1-3).

<P>The charged-particle multiplicity distribution and the transverse-energy distribution measured in heavy-ion collisions at top RHIC and LHC energies are described using the two-component model approach based on a convolution of the Monte Carlo Glauber model with the Weibull model for particle production. The model successfully describes the multiplicity and transverse-energy distribution of minimum-bias collision data for a wide range of energies. The Weibull-Glauber model can be used to determine the centrality classes in heavy-ion collisions as an alternative to the conventional negative binomial distribution (NBD)-Glauber approach.</P>

<P>Selection of an appropriate coagulant for removal of chemical oxygen demand (COD) and turbidity from wastewater generated in a pharmaceutical industry was demonstrated. The standard jar test procedure was adopted to determine the optimum pH and coagulant dosage needed for enhanced COD and turbidity removal. Alum and bentonite (montmorillonite) were chosen as coagulant and coagulant aid, respectively. Based on the results obtained from experiments, COD removal (CODRE, %) and turbidity removal (T-RE, %) were optimized using response surface methodology. Under the optimum conditions, the model predicted a CODRE of 67% and T-RE of 90% and CODRE of 55% and T-RE of 70% using alum (coagulant dosage = 0.79 g/L, pH 5.91) and bentonite (coagulant dosage = 0.58 g/L, pH 5.61), respectively. Confirmatory experiments conducted on the optimized condition showed experimental findings within 5% of the projected values. Though alum resulted in higher CODRE and T-RE as compared to bentonite, bentonite can have the advantage of being environmentally benign when compared to the conventionally used coagulant, alum.</P>
Free vibration of Levy-type rectangular laminated plates using efficient zig-zag theory
Behera, Susanta,Kumari, Poonam Techno-Press 2018 Advances in computational design Vol.3 No.3
First time, an exact solution for free vibration of the Levy-type rectangular laminated plate is developed considering the most efficient Zig-Zag theory (ZIGT) and third order theory (TOT). The plate is subjected to hard simply supported boundary condition (Levy-type) along x axis. Using the equilibrium equations and the plate constitutive relations, a set of 12 m first order differential homogenous equations are obtained, containing displacements and stress resultant as primary variables. The natural frequencies of a single-layer isotropic, multi-layer composites and sandwich plates are tabulated for three values of length-to-thickness ratio (S) and five set of boundary conditions and further assessed by comparing with existing literature and recently developed 3D EKM (extended Kantorovich method) solution. It is found that for the symmetric composite plate, TOT produces better results than ZIGT. For antisymmetric and sandwich plates, ZIGT predicts the frequency for different boundary conditions within 3% error with respect to 3D elasticity solution while TOT gives 10% error. But, ZIGT gives better predictions than the TOT concerning the displacement and stress variables.

Background: The standard adjuvant therapy for transmural and/or node +ve rectal cancer is the combination of pelvic radiation with 5FU based chemotherapy, which significantly improves both local control and overall survival. The addition of concurrent chemotherapy to neoadjuvant radiotherapy increases pathological complete response and down staging occurs in about 60% and which may facilitate sphincter preserving surgery in distally located tumors Methods: A total of 50 patients of locally advanced carcinoma rectum were studied from July 2010 to December 2011. Patients with clinical T3 / T4 and N1/N2 cancer of distal rectum were subjected to receive concurrent chemoradiation followed by surgical resection. All the patients were given Tab. Capecitabine@825 mg/m2 twice concurrently with radiation of 45 Gy/25# @ 1.8 Gy for 5 weeks. Surgery was performed 4-6 weeks after completion of chemoradiation. Tumor downstaging and sphincter preservation were the primary endpoints. Acute normal tissue toxicities were taken into account as secondary point. Postoperatively patients with high risk pathological features were treated with adjuvant chemotherapy with FOLFOX regimen. Results: This regimen resulted in overall resectability rate of 75% and a sphincter preservation rate of 40%. The complete pathological response rate was 40%. Diversion colostomy was done in 25% patients who were declared inoperable. Non hematological toxicities viz: diarrhea grade III = 21% and skin reaction grade II =16%; grade III= 5%). Grade II neutropenia (5%) and grade I thrombocytopenia (2%) were the hematological toxicity observed. With a median follow up period of 9 months no loco-regional failure has been seen. Conclusions: Concurrent preoperative chemoradiation for locally advanced carcinoma rectum is associated with improved tumor resectability which results in improved sphincter preservation, local control and is relatively safe, effective and well tolerated.
