Assessment of Physico-Chemical Characteristics of Lakshmipuram Lake, Anakapalli Dist., Andhra Pradesh, India
No full textLakes are dynamic systems that respond to various physico-chemical characteristics. This paper deals with the physico-chemical analysis of lakshmipuram Lake of lakshmipuram village, Anakapalli Dist., Andhra Pradesh, India. This study was carried out for the period of one year (January – December 2024) to know the quality of water by examining levels of varying physio- chemical parameters such as temperature, pH, turbidity, conductance, alkalinity, DO, BOD, COD, salinity, TDS, TSS, TH, calcium, magnesium, chloride, nitrate-nitrogen, and phosphate. All the key water quality parameters are studied by following standard APHA analytical techniques. The results revealed that there was significant seasonal variation in some physico- chemical parameters and most of the parameters were in a normal range and they are present in the prescribed limits of WHO and National Lake Water Quality Criteria and Standards. It has been identified that the water is of better quality for fish farming and irrigation
Identification Notes of Johnius Fishes from Bay of Bengal Coast, Andhra Pradesh, India
No full textFishes are commercially valuable vertebrates, easily accessible protein sources for all human populations despite of their financial status. Andhra Pradesh has one of the longest coastal lines in the country, and largely partaking in the production of marine products and influencing the state as well as the country’s exporting capacity. Johnius of family Sciaenidae is one of the highly preferred consumable fish species. Our recent studies revealed five species of Johnius occurrence in coastal of waters of Andhra Pradesh and discussed here as identification notes. We observed high sales of small fish species of Johnius at local vendors in all landing centres and sized fishes exporting through the different agencies was also noted and more accurate studies suggested to know the statistical data of Johnius fish species because of commercial importance
Studies on Fecundity and Ova Diameter of the Near Threatened Indian Butter Catfish [Ompak bimaculatus (Bloch, 1794)] from Vamsadhara River, Andhra Pradesh, India
No full textOmpok bimaculatus (Bloch 1794) is a near threatened catfish of freshwaters, belongs to the family Siluridae of the order Siluriformes. Due to its rich lipo-protein content and soft bony structure it becomes delicious and nutritiously highly valuable food fish species. At present Ompok bimaculatus facing decline in the natural populations, due to several anthropogenic factors such as indiscriminate fishing during the breeding season, unscientific use of pesticide in agricultural fields, gradual siltation in the freshwater habitat, depletion of water velocity as a result of decrease in water volume etc. Because of such drastic reduction in its population and a very restricted distribution in the freshwater ecosystem, Present work aims to an experimental analysis of reproductive biology of Ompok bimaculatus. Standardized knowledge on factors like fecundity, ova diameter, maturity, sex-ratio, and spawning are essential pre-requisites in fishery management and conservation. For understanding the dynamics of the gonads and to assess reproductive performance of species information of the phase of gonad development is virtually importan
Analysis And Versatile Uses Of Indian Cow Urine A Review. ...
No full textIn Ayurveda, cow urine (Gomutra) occupies a unique place and has been recognized as water of life or “Amrita”. Urine collection is one of the most basic procedures in animal experiments such as hormone trials and nitrogen balance studies. Because of the complicated structure of the urinary anatomy, there has previously been no perfect apparatus and method to collect urine continuously and precisely from cows and heifers without having negative effects on their health and performance. This is also one of the reasons that bulls and steers are used as replacements in many experiments. Scientific results may not be applicable because of the huge differences in the aspects of physiological structure, nutrient requirements, and metabolic characteristics between cow
Food and Feedings of Mystus tengara (Hamilton, 1822) from Nagavali River, Andhra Pradesh, India
No full textSmall indigenous fish species perform vital role in indigenous people food habitat and their empowerment. Mystus tengara is a well-known and commonly available food fish species, and one of the candidate ornamental fish species in ornamental fish firms. A total of 145 specimens of Mystus tengara (Hamilton, 1822) species were collected from a small distributary of Nagavali River of Andhra Pradesh. 35 food items were observed in the gut of Mystus tengara. The present study has been performed on the food and feeding habits, Gastro Somatic Index, Relative Length of Gut, Fullness and feeding Intensity, and Gut Content Analysis of Mystus tengara. Present study results very close to the earlier studies and revealed that Mystus tengara is a carnivorous fish and zooplankton is the basic food group for this fish species and observed food and feeding indicating sustainable growth and development in different river environments
The Nested Structure of Cancer Symptoms
No full textSummary
Objective: Although many cancer patients experience multiple concurrent symptoms, most studies have either focused on the analysis of single symptoms, or have used methods such as factor analysis that make a priori assumptions about how the data is structured. This article addresses both limitations by first visually exploring the data to identify patterns in the co-occurrence of multiple symptoms, and then using those insights to select and develop quantitative measures to analyze and validate the results.
Methods: We used networks to visualize how 665 cancer patients reported 18 symptoms, and then quantitatively analyzed the observed patterns using degree of symptom overlap between patients, degree of symptom clustering using network modularity, clustering of symptoms based on agglomerative hierarchical clustering, and degree of nestedness of the symptoms based on the most frequently co-occurring symptoms for different sizes of symptom sets. These results were validated by assessing the statistical significance of the quantitative measures through comparison with random networks of the same size and distribution.
Results: The cancer symptoms tended to co-occur in a nested structure, where there was a small set of symptoms that co-occurred in many patients, and progressively larger sets of symptoms that co-occurred among a few patients.
Conclusions: These results suggest that cancer symptoms co-occur in a nested pattern as opposed to distinct clusters, thereby demonstrating the value of exploratory network analyses to reveal complex relationships between patients and symptoms. The research also extends methods for exploring symptom co-occurrence, including methods for quantifying the degree of symptom overlap and for examining nested co-occurrence in co-occur-rence data. Finally, the analysis also suggested implications for the design of systems that assist in symptom assessment and management. The main limitation of the study was that only one dataset was considered, and future studies should attempt to replicate the results in new data.</jats:p
