An expert system entitled 'Wood Anatomy Information System (WAIS)' has been developed for assisting in wood research, wood images display and wood identification. The software is quite comprehensive with provision for all details related to FRI Xylarium and anatomical structure of Indian hardwoods. It is user friendly and has five modules viz. feature description; data input and image display; wood identification; query; and report generation. The database on wood microstructure is developed using standard list of anatomical characters given by International Association of Wood Anatomists (IAWA). The same is used in deciphering information of interest and comparing different data sets of various families, genera and species. The data thus generated shall help in establishing phylogenetic relationship, microstructure variation, homogeneity and heterogeneity within families, relationship between features and above all in wood identification. Since the woods are studied on three planes therefore Wood Images of all the three surfaces viz transverse, radial and tangential shall be stored in this package. The same will serve the purpose of wood structure atlas. The system carries out identification through binary search. The computer filters as per the selected features and gives option of best subsequent feature that can narrow down the search considerable. Thus in about four to five steps the identification of an unknown wood sample can be achieved. This identification module has the flexibility of skipping the features not known to the user. Through Querying module selected taxa can be related to selected features so as to reflect upon the structural affinity between various features, species, genus and families. The Report module generates identification key for the family, genera or species.- Studies on the Effect of Spacing on the Wood Quality in some Clones of Populus deltoides

Variation in specific gravity and wood parameters was studied in 10 year old trees of 18 clones of Populus deltoides with promising growth rate. The sample discs were taken out at different heights viz. breast height, 25%, 50% and 75% of merchantable tree height. To study radial variation, each annual ring was sampled. Significant interclonal differences were observed in anatomical parameters and specific gravity while trees, within clones showed no significant effect. The specific gravity was found to be positively correlated with age, fibre length and vessel frequency and negatively related with fibre diameter and lumen diameter. A negative correlation was also observed between specific gravity and ring width. Within a tree, height and position of annual ring from pith had significant effect on fibre length, lumen diameter, vessel frequency and specific gravity. The specific gravity reaches maximum at 50% of tree height and fibre length at 25% of tree height showing decreasing trend upwards. At breast height fibre length and specific gravity increases rapidly pith outwards upto 6th year followed by a slower rate of increase upto 8th year with a tendency to level off from 8th year. Breast height values of specific gravity and fibre length have been found to be highly correlated with whole tree values for these two parameters. For the prediction of whole tree values from breast height values, regression models and multiplication factors have been derived for fibre length and specific gravity.- Wood Anatomy of Indian Shrubs: Part I- Family Lamiaceae

Anatomical parameters of wood quality such as fibre characteristics, vessel frequency and diameter and proportion oftissues were examined in 8 year old trees of six Populus deltoides clones growing in plantations. Statistical analyses were conducted to determine clonal variations and effect of age on anatomical properties. The analysis indicated significant clonal variation in specific gravity, fibre length vessel length, fibre diameter, lumen diameter, vessel frequency and vessel diameter. The specific gravity, fibre lengt.h and vessel length also show an increase with age. The specific gravity has been found to be positively correlated with fibre length in all the clones but with vessel diameter only in 4 clones. A relative correlation was also observed between vessel area and specific gravity. Cell type percentage was not found to be significantly different among the clones but increase in fibre percentage is found to be related to the decrease in vessel percentage. The variation in wood quality parameters studied offers possibilities for selection of breeding stock with desirable wood quality.- Patterns of Rarity and Endemism in Flowering Plants - a New Approach in Conservation Planning

Indian Forester, Vol 122, No 9 (1996), Pagination: 804-807Abstract
India is well known for its great biodiversity. In order to protect it, over 470 protected areas have been created so far. Mainly on the basis of faunal wealth. Floral wealth had not given its due place specially at species level. The major reason for this being lack of adequate information on localities of important plant species, this leading to a gap on where to protect plant resources. In view of the above a methodology was evolved to find out potential sites on the basis of data related to rare endemic plant. A relationship was drawn between broad distribution and frequency of collection to assess possible rarity value of each significant taxa. This methodology provides objectivity to selection of potential sites for plant conservation.- Wood Microstructure Studies of the Order Oxalidales from Erstwhile India

Bamboo has been widely used as building material throughout the world. There are about 1200-1500 species of bamboos. The bamboo culm sheath shapes provide valuable data in identification of bamboo species. Automated recognition of bamboo has not yet been well established mainly due to lack of research in this area, non-availability and difficulty in obtaining the database. Using digital image processing and pattern recognition techniques, a supervised classification procedure of three different bamboo species has been developed. In the proposed work, an automated bamboo species recognition system based on shape features of bamboo culm sheath has been developed by calculating the Legendre moment. A confusion matrix is created to quantify the class wise and the classifier accuracy. The system can eliminate the need for laborious human recognition method requiring a plant taxonomist. The results obtained shows considerable recognition accuracy proving that the techniques used is suitable to be implemented for commercial purposes.Keywords

Confiscated wooden artifacts in the form of sculpture, boxes, beds belonging to 14 -19 centuries were studied for their wood type. Based on very small wood chips taken out from the artifacts, the wood identification was carried out. The artifacts were found to be made up of Juniperus species, Madhuca longifolia (Mahua), Tectona grandis (Teak), Pterocarpus marsupium (Bijasal), Ficus species and Acacia species. All these woods except for Ficus are well known woods famous for their durability and strength. The choice of species of these woods for furniture and sculpture is indicative of good knowledge of wood properties during those times.Keywords

Chaetomium species which are normally found in soil and organic compost are noted for the presence of secondary metabolite with biological activities. Secondary metabolites from culture filtrate of Chaetomium globosum Kunze were extracted by solvent extraction method using ethyl acetate and separated by thin layer chromatography in five major bands of different Rf values. These compounds were further purified and fractioned with column chromatography. Compound '1' eluted with hexane (fraction 1-18) as color less liquid (Rf 0.84), and other five compounds (2,3,4,5,6) with different ratio of hexane, benzene and acetone as solvent in different fractions as: 34-63 (Rf. 0.46), 71-75 (Rf 0.31), 78 (Rf 0.58), 76-77 (Rf 0.58) and 85-89 (Rf 0.47) were eluted and purified. GS-MS and NMR studies revealed that compounds 2-6 were identical to spectral data of metabolites, chaetomin, BHT, mollicelin G, isomer of mollicelin G and cochiliodinol respectively. One more elution with benzene: acetone (95 : 5 v/v) gave a pale yellow crystalline compound of Rf 0.37 identified as chaetoglobosin. Bioassay studies with two compounds i.e., chaetoglobosin and chaetomin revealed significant growth inhibitory activity against various plant pathogens such as Bipolaris sorokiniana, Macrophomina phaseolina, Rhizoctonia solani and Pythium ultimum under in vitro conditions.Keywords

The worth of a civilization can be judged from the position that it gives to women. Women's role in our society as a caregiver cannot be ignored. Twenty-four hours a day, seven days a week, whether their children are sick, their husbands are out of work or their parents are old and frail and need attending, they will cope. Mental health problems are increasing part of health problems now-a-days around the world. Mental health problems are common at all stages of life. People are not aware of concept of mental health. Even the educated person and medical personnel are not well aware of mental hygiene and positive mental health. The present paper reviews common mental health problems of women in India and their protective factors.Keywords

Wood microstructure with systematic, ecological and evolutionary aspects of six species of Croton L. (Euphorbiaceae) from India is described. Wood is diffuse porous, radial multiples of 4 or more common with some short radial multiples and solitary vessels. Perforation plate simple, intervessel pits rounded and alternate. Fibre libriform, non-septate and thin to thick walled. Parenchyma apotracheal, diffuse to diffuse in aggregate and reticulate or narrow banded. Rays heterocellular, containing non-chambered prismatic or rhomboidal crystals and druses. Disjunctive ray parenchyma walls and perforated ray cell observed. C. scabiosus and C. malabaricus show distinctness in some ray and vessel characteristics. Species show adaption to highly mesic condition except C. scabiosus. Few remnants of wood anatomy are evident of both primitive and advance characters in this genus. Systematic wood anatomical survey shows its close relation to subgenus Croton and distance relation to subgenus Moacroton and sister groups of genus Croton, such as, Cubacroton, Brasiliocroton, Acidocroton and Astrea.Keywords

The massive amount of data collected by various fields is a challenging aspect for analysis using the available storage technologies. Relational databases are a traditional approach of data storage more suitable for structured data formats and are constrained by ACID properties. As the modern world data in the form of word documents, pdf files, audio and video formats is unstructured, where tables and schema definition is not a major concern. Relational databases such as Mysql may not be suitable to serve such Bigdata. An alternate approach is to use the emerging Nosql databases. This paper presents a comparative analysis of Nosql types such as Hbase, Mongodb, Simple DB and Big Table with relational database like Mysql and specifies their limitations when applied to real world problems. It also proposes solution to overcome these limitations using an integrated data store which serve to be beneficial over the mentioned Nosql and Mysql stores in terms of efficiently implementing simple and complex queries yielding better performance.Keywords

The present paper provides comprehensive wood anatomical survey of seven Indian species belonging to two genera Briedelia and Cleistanthus of the tribe Briedelieae (Euphorbiaceae s.l.). Wood microstructure of Cleistanthus found heterogeneous in certain extent within tribe. Systematic relationships between Briedelia and Cleistanthus were evaluated. The systematic wood anatomical study did not favour the recent morphological and molecular phylogenetic circumscription of classification of the tribe. Cleistanthus showed adaptation to xeric environment and Briedelia showed adaptation to mesic environment. Briedelia contain most of advance wood anatomical features while Cleistanthus had a combination of both advance and primitive wood anatomical features.Keywords

Digitalized and informative era invites new avenues to explore and invent. Invention so far is undermined as original creator is not equally rewarded and awarded IPR turned as rolling coin for all originators and gained revolutionary acceptance in all areas and industries: pharmaceutical to steel, printing to software, energy to mining, electrical to hospitality, music, art, literature and films to arm industry. Copyright, Patent, Trademark, License are the buzzwords but unexplored by academicians and learning resources. Today, teacher as a mentor/facilitator are more engrossed in creating original study material, interesting and attractive to bring more participants in the classes. IPR is the shield encompassing a wide variety of rights pertaining and protecting the ownership of creative work. Exploratory research was conducted to analyze the major perceived challenges of IPR, impact of demographic profile on IPR, usage of social networking sites as teaching and learning process.Keywords

Over the past many years, Human Resource Management has changed. It has moved from an operational discipline towards a more strategic discipline. The popularity of the term Strategic Human Resource Management (SHRM) exemplifies this. The data-driven approach that characterizes HR analytics is in line with this development. By using HR analytics organizations do not rely on gut feeling anymore. Analytics enables HR professionals to make data-driven decisions. Furthermore, analytics helps to test the effectiveness of HR policies and different interventions. The use of data analytics in the field of human resource development is becoming increasingly common. This rise in popularity is accompanied by skepticism about the ability of human resource professionals to effectively utilize data analytics to reap organizational benefits
The HR world is abuzz with talk of big data and the transformative potential of HR analytics. With the changing processes HR analytics is a ‘must have’ capability that will ensure HR's future as a strategic management function while transforming organisational performance for the better. It argues that unless the HR profession wises up to both the potential and drawbacks of this emerging field and engages operationally and strategically to develop better methods and approaches, it is unlikely that existing practices of HR analytics will deliver transformational change. Indeed, it is possible that current trends will seal the exclusion of HR from strategic, board‐level influence while doing little to benefit organisations and actively damaging the interests of employees
