Corporate social disclosures in the knowledge-based sector in an emerging economy

The purpose of this paper is to examine corporate social responsibility (CSR) reporting by the BSE TECk Sector in the developing economy of India. Using content analysis, this study analyses the disclosures of corporate social responsibility elements by the BSE TECk Sector in the annual reports. CSR disclosures are analysed in context of sources, nature and the item of information.The findings of the study advice that all the companies in the BSE TECk index disclose social issues in their annual reports. Human resources related issues have found greater attention in annual report of the sample companies and less attention has been provided to ethical issues. The study highlights that it is important for the corporate sector to disclose CSR related matters as part of their overall corporate and business performance reporting model. The paper also provides some practical implications about reporting of socially responsible activities for knowledge based companies

Explorando la eficacia del biocontrol de Trichoderma spp. contra Fusarium sacchari, el agente causal de la marchitez de la caña de azúcar

Wilt caused by Fusarium sacchari, is one of the major diseases of sugarcane (Saccharum spp.) causing considerable economic loss. Trichoderma spp. are important biocontrol agents which have been exploited effectively for the management of several plant diseases including wilt in various crops. The present study was undertaken to evaluate the antagonistic potential of Trichoderma spp. against sugarcane wilt pathogen. A total of 103 Trichoderma isolates comprising of 43 isolates established from sugarcane rhizosphere soils as well as 60 endophytic isolates established from root, leaf and stalk tissue of sugarcane were assessed for their antagonistic activity against F. sacchari by dual culture technique. We observed considerable variability in the inhibitory activity of the 103 isolates against the pathogen with inhibition ranging from 1.4% to 27.2% (SER42). In general, the endophytic Trichoderma isolates were more effective in inhibiting F. sacchari as compared to rhizospheric isolates in dual culture studies. Twelve most promising endophytic isolates were selected and assessed further for production of soluble inhibitory metabolites against F. sacchari by poison food technique. Variability was observed among the Trichoderma isolates in inhibition of F. sacchari growth with inhibition ranging between 1.4% (SER 43) to 44.2% (SER10). Overall, based on the in vitro assays, Trichoderma isolate SER 10, isolated from root tissue of sugarcane, was found most promising showing 44.2% inhibition of F. sacchari growth in poison food and 26.3% inhibition in dual culture studies. This is the first study reporting biocontrol potential of endophytic Trichoderma spp. against F. sacchari, a causative agent of wilt in sugarcane.La marchitez causada por Fusarium sacchari, es una de las principales enfermedades de la caña de azúcar (Saccharum spp.) que causa considerables pérdidas económicas. Trichoderma spp. es un importante agente de biocontrol que se ha explotado eficazmente para el manejo de varias enfermedades de las plantas, incluida la marchitez en varios cultivos. El presente estudio se realizó para evaluar el potencial antagonista de Trichoderma spp. contra el patógeno de la marchitez de la caña de azúcar. Un total de 103 aislamientos de Trichoderma que comprenden 43 aislamientos establecidos a partir de suelos de la rizosfera de la caña de azúcar, así como 60 aislamientos endofíticos establecidos a partir del tejido de las raíces, hojas y tallos de la caña de azúcar, fueron evaluados por su actividad antagonista contra F. sacchari mediante la técnica de cultivo dual. Se observó una considerable variabilidad en la actividad inhibidora de los 103 aislamientos contra el organismo patógeno con una inhibición que osciló entre 1.4% y el 27.2% (SER42). En general, los aislados endofíticos de Trichoderma fueron más efectivos en la inhibición de F. sacchari en comparación con los aislados rizosféricos en estudios de cultivo dual y se seleccionaron 12 aislados endofíticos prometedores que se evaluaron más a fondo para la producción de metabolitos inhibidores solubles contra F. sacchari mediante la técnica de medios de cultivo envenenados. Se observó variabilidad entre los aislados de Trichoderma en la inhibición del crecimiento de F. sacchari con valores que oscilaban entre el 1.4% (SER 43) y el 44.2% (SER10). En general, según los ensayos in vitro, Trichoderma SER 10, aislado del tejido de la raíz de la caña de azúcar, resultó ser el más prometedor que mostró una inhibición del 44.2% del crecimiento de F. sacchari en el método de medio de cultivo envenenado y un 26.3% de inhibición en los estudios de cultivo dual. Este es el primer estudio informa sobre el potencial de control biológico de Trichoderma spp. contra F. sacchari, agente causal de la marchitez en la caña de azúcar

Plant phenological response to microclimatic variations in an alpine zone of Garhwal Himalaya

The impact of microclimatic variations on the developmental stages of common alpine plant species at four primary phenology sites at Dayara meadow of Garhwal Himalayas (Uttarakhand) was studied. The study revealed that the variations in the topographical features and environmental conditions directly influenced the phenology of the alpine plant species. Site I and IV showed great variation in the timing of phenological phases whereas, site III and IV showed approximately similar phenological timings. Anemone obtusiloba and Anaphalis contorta showed early flowering whereas Aconitum heterophyllum, Bupleurum longicaule and Parnassia nubicola flowered in late August and early September. P. nubicola had a shorter flowering period whereas Tanacetum longifolium.and A. nepalensis had the longest flowering period. Taraxacum officinale and Geum elatum flowered twice in the season

Delayed formation of pulmonary artery stump thrombus: a case report and review of the literature

Pulmonary artery stump thrombosis is a recognized complication after pneumonectomy. However, to our knowledge, there is only one case report of delayed development of this complication. We report the case of a 68 year-old man who presented with chest pain nearly ten years after undergoing a right pneumonectomy for lung cancer. Workup identified a pulmonary artery stump thrombosis. Due to the acute onset of his symptoms, the patient was anticoagulated, and his chest pain resolved. While the literature suggests that anticoagulation is not generally required for stump thromboses, we highlight features of this case that may indicate an increased risk of clinically important sequelae. Taking previous reports into account, we argue that a specific subset of patients with stump thrombosis may benefit from systemic anticoagulation

Comparative study of hexane extract for volatile and non volatile components of leaves and rhizomes of Acorus calamus linn. using high performance thin layer chromatography (HPTLC)

The present communication attempts to evaluate the comparative study of leaves and rhizomes of Acorus calamus Linn. (Family; Araceae) using High Performance Thin Layer Chromatography (HPTLC). Since the plant contains various volatile and non-volatile components so paper advocates the quantitative study using hexane extract. Acorus calamus Linn. is a well known medicinal plant in traditional medical systems  having various ethno-pharmacological uses. As the official source of the plant is roots and rhizomes, but here study had been done comparatively with leaves. Previously leaves of Acorus calamus were not regarded as useful part of plant, but recently there is growing interest in leaves of the said plant. The leaves are considered to possess various activities such as an insect repellent, when cut up and kept with grain storage; anti-hyperlipidemic; anti-diabetic; antipsychotic; anti-inflammatory and analgesic. As there is no detailed work reported in leaf constituents of the plant, therefore the study revealed specific quantitative HPTLC data for the plant for future standardization work. HPTLC analysis of both leaves and rhizomes showed the presence of Asarone, β- sitosterol, lupeol and Ursolic acid when matched with marker compounds

Secure E-mailing System Using Pair Based Scheme and AES with Session Password

In early days Textual passwords are used for security of session but these passwords are vulnerable to the various attacks like Dictionary attack, Shoulder surfing, eves dropping, etc. Further graphical passwords and bio-metric passwords are invented. These two techniques are good performer but they have their own disadvantages. Such as requires extra time for login and more cost respectively. Thus we proposed a session password scheme in which the passwords are used only once for each and when session is terminated the password is no longer in use. The proposed of session password scheme uses Pair Based Authentication scheme for generating session password. In every Data communication system security to data is primary aim. Data security can be provided by many ways. This Paper gives a design of effective security for data communication in network by AES algorithm for encryption and decryption

Solution of the Burger\u27s Equation for Longitudinal Dispersion Phenomena Occurring in Miscible Phase Flow Through Porous Media

An approximate solution of longitudinal dispersion phenomena occurring in two phase miscible fluid flow through porous media has been obtained by using the group theoretic approach. The longitudinal dispersion coefficient is assumed to be directly proportional to the concentration of the fluid for a distance x and at any time t > 0. The graphical representation for the concentration of the fluid for a distance x and at time t > 0 has been obtained using Mat lab coding
