Abstract:
In today's complicated computing environment, managing data has become the primary concern
of all industries. Information security is the greatest challenge and it has become essential to secure the
enterprise system resources like the databases and the operating systems from the attacks of the unknown
outsiders. Our approach plays a major role in detecting and managing vulnerabilities in complex
computing systems. It allows enterprises to assess two primary tiers through a single interface as a
vulnerability scanner tool which provides a secure system which is also compatible with the security
compliance of the industry. It provides an overall view of the vulnerabilities in the database, by
automatically scanning them with minimum overhead. It gives a detailed view of the risks involved and
their corresponding ratings. Based on these priorities, an appropriate mitigation process can be
implemented to ensure a secured system. The results show that our approach could effectively optimize
the time and cost involved when compared to the existing systems

Regional climate models are becoming increasingly popular to provide high resolution
climate change information for impacts assessments to inform adaptation options.
Many countries and provinces requiring these assessments are as small as 200,000 km2
in size, significantly smaller than an ideal domain needed for successful applications of
one-way nested regional climate models. Therefore assessments on sub-regional scales
(e.g., river basins) are generally carried out using climate change simulations performed for
relatively larger regions. Here we show that the seasonal mean hydrological cycle and
the day-to-day precipitation variations of a sub-region within the model domain are
sensitive to the domain size, even though the large scale circulation features over the region
are largely insensitive. On seasonal timescales, the relatively smaller domains intensify the
hydrological cycle by increasing the net transport of moisture into the study region and
thereby enhancing the precipitation and local recycling of moisture. On daily timescales,
the simulations run over smaller domains produce higher number of moderate precipitation
days in the sub-region relative to the corresponding larger domain simulations. An
assessment of daily variations of water vapor and the vertical velocity within the sub-region
indicates that the smaller domains may favor more frequent moderate uplifting and
subsequent precipitation in the region. The results remained largely insensitive to the
horizontal resolution of the model, indicating the robustness of the domain size influence
on the regional model solutions. These domain size dependent precipitation characteristics
have the potential to add one more level of uncertainty to the downscaled projections.

Abstract:
The gel strength, compressibility and folding characteristic of suwari (set) and kamaboko (set and cooked) gels prepared from rohu (Labeo rohita), catla (Catla catla) and mrigal (Cirrhinus mrigala) surimi were examined to understand the occurrence of suwari and modori phenomena in surimi from major freshwater carps. Suwari setting of gels did not take place at lower temperatures. Suwari gels showed good gel strength at 50 °C for rohu and at 60 °C for catla and mrigal after 30 min setting time. Incubation for 60 min decreased the gel strength at 60 °C for rohu and catla. Setting at 25 °C followed by cooking at 90 °C increased the gel strength. Increased setting temperature, however, decreased the gel strength of cooked gels. Gel strength and compressibility data were supported by folding characteristics.

Abstract:
The characteristics and stability of natural actomyosin (NAM) from rohu (Labeo rohita), catla
(Catla catla) and mrigal (Cirrhinus mrigala) were investigated. The total extractable actomyosin (AM)
was higher (7.60mgml−1) in the case of rohu compared with that from catla and mrigal (5mgml−1).
Although the specific AM ATPase activity was similar (0.43–0.5 μmolPmin−1 mgP−1) among the three
species, the total ATPase activity was lower in mrigal (25 μmol g−1 meat) compared with the other species
(37 μmol g−1 meat). The inactivation rate constants (kd) of AM Ca ATPase activity showed differences in
the stabilities of actomyosin among these fish, the actomyosin from catla being least stable. The NAM
from these species was stable up to 20 ◦C at pH 7.0. Catla AM became unstable at 30 ◦C, while rohu and
mrigal AM could withstand up to 45 ◦C. The thermal denaturation with respect to solubility, turbidity,
ATPase activity, sulphhydryl group and surface hydrophobicity showed noticeable changes at around
these temperatures
