Physicochemical and Biochemical Reclamation of Soil through Secondary Succession  [PDF]
Kamala Haripal, Sunanda Sahoo
Open Journal of Soil Science (OJSS) , 2013, DOI: 10.4236/ojss.2013.35028
Abstract:

Conversion of forest to agricultural fields has become a common practice in India. Very often these fields have been abandoned due to lack of sustainable production. In course of time these fallow lands undergo natural secondary succession. Present study was carried out to find out the restoration of soil physicochemical and biochemical properties in a chronosequence of 2 yr, 4 yr, 6 yr, 11 yr, and 15 yr fallow lands. Soil enzyme activities play key roles in the biochemical functioning of soils, including soil organic matter formation and degradation, nutrient cycling, and reflect the change in soil management and land use. There was gradual improvement in the physical condition and nutrient status along with increase in soil amylase, cellulase, dehydrogenase, phophatase, and urease activity in the present study with the progress of fallow age which indicates the importance of natural secondary succession in soil restoration. However the PCA analysis indicated that natural vegetational succession could reclaim the soil quality and promote ecosystem restoration but it required a long time under the present local climatic condition.

Vegetational dynamics in some tropical abandoned rice fields in the western part of Orissa, India
K Haripal, S Sahoo
African Journal of Environmental Science and Technology , 2011,
Abstract: In many areas of tropics, agroecosystems are developed by clearing the natural forests. Conversion of natural forests to agricultural systems leads to loss of several soil ecological attributes responsible to maintain the soil fertility. Therefore in such converted agroecosystems the soil fertility often declines. In order to meet the deficiency of soil fertility, the farmers adopt the practice of nutrient input to such agricultural systems. However, poor farmers of tropics being unable to adopt such soil management strategy abandon the agricultural systems because of decline in production and leave the fields to remain fallow. The present study examined the vegetational succession and quantitative community characteristics in some abandoned agricultural ecosystems of western part of Orissa, India. The phytosociological attributes in different abandoned rice fields were studied by taking quadrates of suitable sizes (1 × 1, 5 × 5 and 10 × 10 m2 for herbaceous grass and nongrass, shrubs and tree species respectively). Quantitative community characteristics like frequency, abundance, density of different plant species, diversity and dominance index were examined. Importance Value Index (IVI) was calculated to understand the importance of individual species in a community. The distribution patterns of different species were analyzed by species sequence curve method. Our finding showed that there is decrease in the number of grass stands and increase in the nongrass stands with the increase in the year of fallow periods. The study also indicated an increasing trend of species richness, abundance and diversity with increasing year of abandonment indicating the growth of secondary succession in this region.
A Survey of Software Test Estimation Techniques  [PDF]
Kamala Ramasubramani Jayakumar, Alain Abran
Journal of Software Engineering and Applications (JSEA) , 2013, DOI: 10.4236/jsea.2013.610A006
Abstract:

Software testing has become a primary business for a number of IT services companies, and estimation, which remains a challenge in software development, is even more challenging in software testing. This paper presents an overview of software test estimation techniques surveyed, as well as some of the challenges that need to be overcome if the foundations of these software testing estimation techniques are to be improved.

Estimation Models for Software Functional Test Effort  [PDF]
Kamala Ramasubramani Jayakumar, Alain Abran
Journal of Software Engineering and Applications (JSEA) , 2017, DOI: 10.4236/jsea.2017.104020
Abstract: The International Software Benchmarking and Standards Group (ISBSG) data-base was used to build estimation models for estimating software functional test effort. The analysis of the data revealed three test productivity patterns representing economies or diseconomies of scale and these patterns served as a basis for investigating the characteristics of the corresponding projects. Three groups of projects related to the three different productivity patterns, characterized by domain, team size, elapsed time and rigor of verification and validation carried out during development, were found to be statistically significant. Within each project group, the variations in test effort can be explained, in addition to functional size, by 1) the processes executed during development, and 2) the processes adopted for testing. Portfolios of estimation models were built using combinations of the three independent variables. Performance of the estimation models built using the function point method innovated by the Common Software Measurement International Consortium (COSMIC) known as COSMIC Function Points, and the one advocated by the International Function Point Users Group (IFPUG) known as IFPUG Function Points, were compared to evaluate the impact of these respective sizing methods on test effort estimation.
Mudando o debate sobre o tráfico de mulheres

Abstract: in this text i present central perspectives and approaches in the international debate about the trafficking of persons, and highlight some of the main points of critique about the contemporary hegemonic framework that are articulated through action-research projects and grassroots anti-trafficking interventions. i argue that despite substantial shifts in global understandings about trafficking, which are heavily influenced by two distinctly different feminist discourses (radical feminism and transnational feminism), today much of what is pursued in the name of a war on trafficking has troubling consequences for poor communities around the world, and has gendered and racialized implications. us anti-trafficking policies are drawn upon here to illustrate some of these tendencies.

Abstract:

Pinus patula is one of the major exotic species grown in Malawi mainly for saw-timber production. It is native to Mexico. Little has been reported about the mechanical properties of the wood. The objective of this study was to investigate the mechanical properties of Pinus patula in more detail, in order to provide a basis for utilizing this resource. The mechanical properties of small clear wood specimens of Pinus patula were evaluated using 40 cm logs from 1, 3, 5, 7 and 9 m above the ground. Small clear wood specimens were selected and subjected to a bending test in accordance with Japan Industrial Standards (JIS) air-dry conditions. The growth rate did not affect the mechanical properties measured. There were significant correlations at 1% level between air-dry density and Modulus Of Elasticity (MOE) (R = 0.85) and between air-dry density and Modulus Of Rupture (MOR) (R = 0.83). There was also a significant correlation between MOE and MOR at 1% level (R = 0.90). At about 12% moisture content, the tested five Pinus patula families have average MOR and MOE of 105.17 MPa and 10.93 GPa, respectively.

Phenolic Compounds, Phytate, Citric Acid and the In-vitro Iron Accessibility of Cowpeas, Mung Beans and Four Varieties of Kidney Beans

Abstract: Iron deficiency anaemia is highly prevalent in Tanzania affecting predominantly children and women of childbearing age. One of the major causes is the low iron bioavailability from vegetarian diets mainly due to the presence of various antinutritional factors that interfere with non-heme iron absorption. Cereals and legumes constitute the main ingredients of diets in the country providing proteins, carbohydrates, minerals and vitamins. Certain varieties of these grains contain large amounts of polyphenolics and phytate that are known to inhibit iron absorption. Varieties of legumes; cowpeas (Vigna unguiculata) and mung beans (Vigna radiata L.) and kidney beans (Phaseolus vulgaris L.) were analyzed for the polyphenolics and phytates. The total and in vitro accessible iron, and the citric acid were also quantified and their nutritional consequences discussed. Phenolic compounds varied widely in the analysed legumes ranging from 3.37 to 9.14 mg catechin equivalent/g and they associated negatively with in vitro accessible iron (r = - 0.367; p = 0.054). The catechol and resorcinol phenolics ranged from 1.58 to 3.51 and 1.41 to 5.37 mg catechin equivalent/g respectively and were relatively higher than galloyls that range from 0.10 to 1.52 mg tannic acid equivalent/g). Phytate ranged from 8.46 to 13.18 mg/g, total iron from 3.58 to 7.55 mg/100g and in vitro accessible iron from 0.45 to 1.04 mg/100g. Citric acid ranged from 70.8 to 205.2 mg/100g and was associated positively with in vitro accessible iron (r = 0.845; p = 0.006). Proper processing of legumes to reduce antinutritional factors to relatively lower levels is important in order to render the iron and other nutrients readily available for absorption.

Abstract: Pythium aphanidermatum is one of the common causal pathogen of damping-off disease of beans (Phaseolus vulgaris L.) grown in Manipur. A total of 110 indigenous Trichoderma isolates obtained from North east India were screened for their biocontrol activity which can inhibit the mycelial growth of P. aphanidermatum, the causal organism of damping-off in beans. Out of the total isolates, 32% of them showed strong antagonistic activity against P. aphanidermatum under in vitro condition and subsequently 20 best isolates were selected based on their mycelial inhibition capacity against P. aphanidermatum for further analysis. Different biocontrol mechanisms such as protease, chitinase, β-1,3-glucanase activity, cellulase and production of volatile and non-volatile compounds were also assayed. Based on their relative biocontrol potency, only three indigenous Trichoderma isolates (T73, T80 and T105) were selected for pot culture experiment against damping-off diseases in common beans. In greenhouse experiment, Trichoderma isolates T-105 significantly reduced the pre- and post-emergence damping-off disease incidence under artificial infection with P. aphanidermatum and showed highest disease control percentage.
