Full textAbstract:
This paper on the role of Fisheries resources in National development is aimed at highlighting the role of Fishery products in Nation building. Fishery products of finned Fish species like Cod, Flounder, Salmon, Catfish, Goldfish, Sea urchins, Shrimps, King crab, Halibut, Mollusk and Echinoderms that come from both capture Fisheries and Aquaculture provide employment, food security, improves welfare, nutrition and a healthy population. Also serve for International trade and foreign exchange in goods like Leather and polishing materials that come from the skin of Cartilagenous Fishes. Ice Fish, dried and canned Fishery products, Salmon roe (egg) and Fish oil used for the manufacture of Soap and Medicinal Oils like the Cod Liver Oil. Fish intake also reduces the condition atherosclerosis thereby combating cardiovascular diseases. However, the Fishery Subsector has some constraints such as by Catch, improper funding, poor input Facilities, Poverty in Fishing Communities, Water barriers, effect of climate change and lack of comprehensive Man power development and training programmes. It is therefore recommended that Government, Donor agencies and international trade unions make effort to increase the educational and capital base of small-scale Farmers; distinguish between Farmed and Wild products, provides Comprehensive Man power and training programmes for all Cadre, providing transportation systems for better appreciation and Productivity in the fishery sub-sector. Laws and by-laws should also be enacted to prevent indiscriminate fishing to avoid over exploitation and extinction of our Aquatic Species.

Full textAbstract:
Polycyclic aromatic hydrocarbons (PAHs) were measured in shrimp samples (Penaeus monodon) of Jones Creek southern Nigeria during the rainy and dry seasons and analysed for 16 priority PAHs. The ΣPAHs ranged from 0.073 to 0.800 mg/kg for shrimp samples collected for the 18 month duration of this study. Fluorene and anthracene were the most dominant PAH observed with concentrations of 0.084 ± 0.010 mg/kg and 0.059 ± 0.007 mg/kg respectively. Fluorene was also the most detected PAH comprising 21.91% of the 16 PAHs detected while benzo(g,h,i)perylene was the least with 0.02%. The source of contamination is closely related to human activities such as domestic and industrial discharges, refining activities and street runoff. High concentrations were recorded during the rainy season and during the first quarter of the year. The investigated samples were classified as minimally contaminated when compared with FDA levels of PAHs in shrimp samples. Distribution patterns showed that PAHs with 3 and 4 rings dominated confirming the pyrogenic source of the detected PAH. Diagnostic ratios such as phenanthrene/anthracene and benzo(a)anthracene/chrysene were achieved to evaluate the emission sources of PAHs. These ratios indicated a pyrolytic source of PAHs for sediments, as well as a pyrolytic or pyrogenic origin of the PAHs detected in the shrimp samples obtained within the study area.Key words: PAHs, sediment, shrimps, cancer risk, diagnostic ratio.

Full textAbstract:
Clove mistletoe (Dendrophthoe pentandra(L.) Miq.) is a semiparasitic plant that belongs to Loranthaceae family. Clove mistletoe was traditionally used for cancer treatment in Indonesia. In the present study, we examined cytotoxicity of clove mistletoe leaves extracts against brine shrimps and conducted their antiproliferative activity on K562 (human chronic myelogenous leukemia) and MCM-B2 (canine benign mixed mammary) cancer cell lines in vitro. The tested samples were water extract, ethanol extract, ethanol fraction, ethyl acetate fraction, and n-hexane fraction. Cytotoxicity was screened using Brine Shrimp Lethality Test (BSLT). Antiproliferative activity was conducted using Trypan Blue Dye Method and cells were counted using haemocytometer. The results showed that n-hexane fraction exhibited significant cytotoxicity with LC50value of 55.31 μg/mL. The n-hexane fraction was then considered for further examination. The n-hexane fraction of clove mistletoe could inhibit growth of K562 and MCM-B2 cancer cell lines in vitro. The inhibition activity of clove mistletoe n-hexane fraction at concentration of 125 μg/mL on K562 cancer cell lines was 38.69%, while on MCM-B2 it was 41.5%. Therefore, it was suggested that clove mistletoe had potential natural anticancer activity.

Background.Inadequate specialized cancer hospitals and high costs are contributing factors that delay cancer patients from accessing health care services in Tanzania. Consequently, majority of patients are first seen by Traditional Health Practitioners (THPs) before they access specialized services. This study presents ethnomedical information and preliminary evaluation of 25 plant species claimed by THPs in Mkuranga and Same districts of Tanzania on use for treatment of cancer. Literature search and laboratory investigation results are presented to support evaluation.Methods. This study was a single disease ethnomedical enquiry focusing on plants being used for cancer treatment.Face-to-face interviews and questionnaires were administered toeight (8) THPsin Mkuranga and Same districts on the claimed plants and their use for management of cancer. Plants were selected based on being frequently mentioned and emphasis given by THPs. Literature search and brine shrimp toxicity (BST) of methanol : dichloromethane (1:1) extracts was used as surrogates to evaluate strength of the claims.Results.This study reports 25 plant species used by the THPs in two districts of Tanzania. Eight plants (32%) have been reported in the literature to have activity against cancer cells. BST results revealed, 14 (56%) plants exhibited high toxicity against brine shrimps. The most active plants includedCroton pseudopulchellusPax (LC504.2μg/ml),Dalbergia melanoxylonGuill. & Perr. (LC506.8μg/ml),Loranthus micranthusLinn (LC504.0μg/ml),Ochna mossambicensisKlotzsch (LC503.3μg/ml), andSpirostachys africanaSond. (LC504.4μg/ml); their toxicity was comparable to that ofCatharanthus roseus(L) G. Don. (LC506.7μg/ml), an established source of anticancer compounds. Nine other plants had LC50values between (19.8 and 71.6)μg/ml, indicating also potential to yield anticancer.Conclusion.Literature search and BST results provide a strong support of the potential of the claimed plants to yield active anticancer compounds.

Full textAbstract:
Therapeutics against breast cancer is a major research field, due to inefficiency or partial efficiency of existing therapeutics. An urge to discover better therapeutics always persists. Our objective is to study salicin against breast cancer cells, in order to find its therapeutic properties. To study the effect of salicin on breast cancer cells, we performed MTT assay on MCF-7 (hormone positive) and MDA-MB-231 (triple negative) breast cancer cell lines, we did brine shrimp lethality test (BSLT) assay to see the lethal effects of salicin. By the help of bioinformatics we tried to locate the targets that delineate salicin activity. Salicin was docked with estrogen receptor (ER), progesterone receptor (PR) and Human epidermal growth factor receptor 2 (HER2) to study its binding efficiency and possible targets of salicin. Salicin remarkably reduces cell viability both in MCF-7 and MDA-MB-231, along with being lethal to brine shrimps. These results together opine that salicin can be an effective therapeutics against breast cancer cells. The mechanism of action of salicin is probably through ER, PR and HER2 receptors because it can efficiently bind these receptors with minimum energy required for binding. This explains that salicin can easily bind to these receptors. These results together opine that salicin can be an effective therapeutics against breast cancer cells. The mechanism of action of salicin is probably through ER, PR and HER2 receptors because it can efficiently bind these receptors with minimum binding energy. ER, PR and HER2 are major reasons behind the disease pathogenicity depending on the type of breast cancer. According to our results salicin may either induce apoptosis or reduce cellular mitosis both via P53 dependent and independent pathway, which makes salicin a good choice of both hormone positive and negative breast cancer cells.

Cancer affects one in three people worldwide. Surgery remains the primary curative option for localized cancers, but good prognoses require complete removal of primary tumors and timely recognition of metastases. To expand surgical capabilities and enhance patient outcomes, we developed a six-channel color/near-infrared image sensor inspired by the mantis shrimp visual system that enabled near-infrared fluorescence image guidance during surgery. The mantis shrimp’s unique eye, which maximizes the number of photons contributing to and the amount of information contained in each glimpse of its surroundings, is recapitulated in our single-chip imaging system that integrates arrays of vertically stacked silicon photodetectors and pixelated spectral filters. To provide information about tumor location unavailable from a single instrument, we tuned three color channels to permit an intuitive perspective of the surgical procedure and three near-infrared channels to permit multifunctional imaging of optical probes highlighting cancerous tissue. In nude athymic mice bearing human prostate tumors, our image sensor enabled simultaneous detection of two tumor-targeted fluorophores, distinguishing diseased from healthy tissue in an estimated 92% of cases. It also permitted extraction of near-infrared structured illumination enabling the mapping of the three-dimensional topography of tumors and surgical sites to within 1.2-mm error. In the operating room, during surgical resection in 18 patients with breast cancer, our image sensor further enabled sentinel lymph node mapping using clinically approved near-infrared fluorophores. The flexibility and performance afforded by this simple and compact architecture highlights the benefits of biologically inspired sensors in image-guided surgery.

Full textAbstract:
Rumex obtusifolius L. (Polygonaceae), commonly known as 'broad-leaf dock', is one of the most common Irish wayside weeds, and it also occurs in silage fields, on river banks, in ditches and on waste grounds. The ethnobotanical uses of this species include its use as an antidote to nettle, depurative, astringent, laxative, and tonic, and in the treatment of sores, blisters, burns, cancer and tumors. The bioactivities of n-hexane, dichloromethane (DCM) and methanol (MeOH) extracts of the leaves of R. obtusifolius were assessed using the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay, the newly developed micro-titer-based antimicrobial assay incorporating resazurin as an indicator of cell growth, and the brine shrimp lethality assay. The most potent free radical scavenging activity was displayed by the MeOH extract with a RC50 value of 7.80 x 10-2 mg/mL. Among the fractions obtained from solid-phase extraction (SPE) of the MeOH extract, the 50% aqueous methanolic SPE fraction exhibited the highest levels of free radical scavenging property (RC50 = 1.05 x 10-2 mg/mL). While the n-hexane extract did not show any antibacterial activity at test concentrations, the DCM extract was active only against Escherichia coli. However, the MeOH extract as well as the 50% and 80% SPE fractions of the MeOH extract showed significant antibacterial property against all bacterial strains tested. None of the extracts or fractions exhibited any significant toxicity towards brine shrimps.

Abstract Medicinal plants belonging to the genus Ardisia are traditionally used to cure various human diseases including inflammation and cancer. This study aimed to purify and characterize cytotoxic and anti-inflammatory compounds from Ardisia sieboldii leaves. Bioassay-guided chromatographic analyses yielded three compounds, 2-methyl-5-(8Z-heptadecenyl) resorcinol (1), 5-(8Z-heptadecenyl) resorcinol (2), and ardisiaquinone A (3), whereas liquid chromatography–electrospray ionisation–mass spectrometry chemical profiling revealed the presence of diverse resorcinol and alkylbenzoquinone derivatives in cytotoxic 70% methanol extracts. Chemical structures of 1–3 were confirmed by spectroscopic methods including 1H NMR (nuclear magnetic resonance), 13C NMR, and electrospray ionisation–mass spectrometry. Compounds 1 and 2 were purified from A. sieboldii for the first time, and all three compounds showed cytotoxicity against a panel of cancer cell lines and brine shrimps in a dose-response manner. Among them, compound 2 exhibited the highest cytotoxicity on cancer cells (IC50 values of 8.8–25.7 μM) as well as on brine shrimps (IC50 value of 5.1 μM). Compounds 1–3 exhibited anti-inflammatory effects through inhibiting protein denaturation (IC50 values of 5.8–9.6 μM), cyclooxygenase-2 activity (IC50 values of 34.5–60.1 μM), and nitrite formation in RAW 264.7 cells. Cytotoxic and anti-inflammatory activities of 1–3 demonstrated in this study deserve further investigation for considering their suitability as candidates or leads to develop anticancer and anti-inflammatory drugs.

Anti-microbial peptides (AMPs) have many functions, such as anti-bacteria, anti-inflammation, and anti-cancer. Considering the anti-bacterial function of AMPs, we initially synthesized a series of truncated AMP derivatives of shrimp anti-lipopolysaccharide factor (SALF), epinecidin-1, and pardaxin. We then determined the minimum inhibitory concentrations (MICs) of these derivatives against eight bacterial species. We also examined the synergistic effect between peptide and non-peptide antibiotics. We found that epinecidin-0217 and pardaxin-0127 exhibited a broad range of activity against Gram-positive and Gram-negative bacteria. Moreover, a combination of these AMPs with antibiotics resulted in a synergistic improvement in the anti-bacterial activity against methicillin-resistant Staphylococcus aureus. Considering the anti-inflammatory function of AMPs, we performed ELISA to show that SALF inhibits the production of inflammatory cytokines, tumor necrosis factor (TNF)-α, interleukin (IL)-1α, IL-6, and IL-1β, as well as the secretion of monocyte chemoattractant protein (MCP)-1 in cervical epithelial cells treated with lipopolysaccharide (LPS). We also conducted RT-PCR to demonstrate that SALF suppresses il-6, il-8, il-1α, and mcp-1 expressions. Moreover, we provided evidence that SALF may regulate vaginal epithelial cell immune responses via mitogen-activated protein kinase (MAPK) and nuclear factor (NF)-κB pathways. We then conducted ELISA to confirm that SALF downregulates the secretion of pro-inflammatory cytokines (TNF-α, IL-1α, IL-6, IL-8, and MCP-1) in cervical epithelial cells infected by Trichomonas vaginalis. We futher employed real-time PCR to show that SALF affects the expression of several pro-inflammatory genes. Conducting Western blot analysis, we demonstrated that SALF treatment inhibits T. vaginalis infection of cervical epithelial cells via p38 and NF-κB pathways. These pathways were observed by using appropriate inhibitors and by performing ELISA/Western blot analysis. Considering the anti-cancer function of AMPs, we investigated the cytotoxic activity of SALF on four cervical cancer cell lines. We performed fluorescence-activated cell sorting analysis to show that SALF induces cervical cancer cell death and G2/M phase arrest in vitro. Furthermore, we observed the localization of SALF to the cytosol and nuclei of human epithelial carcinoma (HeLa) cells at 24 h after treatment by confocal imaging. AO/EtBr and DNA fragmentation results indicated that SALF induces apoptosis in HeLa cells. Moreover, we used various caspase inhibitors in vitro and immunohistochemistry in vivo to show that caspase-3 and caspase-9 are involved in SALF-induced apoptosis. We also showed that SALF induces mitochondrial membrane depolarization associated with caspase-dependent pathway in HeLa cells. Our findings indicated that SALF exhibits promising anti-cancer activity by triggering apoptosis. SALF may be applied in single or combinatorial therapy against cervical cancer. We also reported that epinecidin-0217 and pardaxin-0127 inhibit the growth of HeLa and fibrosarcoma (HT-1080) cells.

In the field of Aquaculture with the help of digital advancements huge amount of data is constantly produced for which the data of the aquaculture has entered in the big data world. The requirement for data management and analytics model is increased as the development progresses. Therefore, all the data cannot be stored on single machine. There is need for solution that stores and analyzes huge amounts of data which is nothing but Big Data. In this chapter a framework is developed that provides a solution for shrimp disease by using historical data based on Hive and Hadoop. The data regarding shrimps is acquired from different sources like aquaculture websites, various reports of laboratory etc. The noise is removed after the collection of data from various sources. Data is to be uploaded on HDFS after normalization is done and is to be put in a file that supports Hive. Finally classified data will be located in particular place. Based on the features extracted from aquaculture data, HiveQL can be used to analyze shrimp diseases symptoms.

Full textAbstract:
Some seabirds or coastal birds such as flamingos or pelicans display elegant pink or reddish colours. These colours are due to pigments that birds cannot synthesize de novo. Thus, this coloration is mainly originated from carotenoids ingested trough carotenoid rich food sources like microalgae (Dunaliella) or small shrimps (Artemia), which are microorganisms inhabiting the salty environments where the mentioned birds live. New advances in this field of knowledge have revealed that extreme microorganisms belonging to the haloarchaea group (Archaea Domain) may contribute significantly to the characteristic pink- red colour of flamingos’ feathers for instance. Alive haloarchaea cells have been found on the surface of the feathers. Besides, the major carotenoid produced by haloarchaea (bacterioruberin) has also been identify within the feathers structure. This work summarizes the main contributions recently reported about this topic as well as general aspects regarding bacterioruberin as a powerful colour carotenoid. Discussions about potential role of these microorganisms in the life of seaside birds are also included.

Full textAbstract:
The cultivation of planktonic crustaceans as live feed is of paramount importance for the aquaculture and aquarium industries. The use of live cladocerans as feed for freshwater fish is limited to the aquarium industry, whereas Artemia and copepods are used to feed edible marine fish larvae with small mouth gape. Live feed production is expensive and time consuming; therefore, it is only used for fish that cannot be fed an inert diet directly, and only until they are ready for weaning to an inert diet. High-quality planktonic crustacean cultures are furthermore used to conduct environmental risk assessments for hazardous chemicals. Cladocerans are widely used for ecotoxicology testing, but Artemia and copepods are emerging as new model species. The present chapter reviews the culturing procedures of these important planktonic crustaceans: Artemia, cladocerans, and copepods. It discusses their use as live feed and as test organisms for environmental risk assessments. The culturing procedures are categorized into three complexity levels: Extensive, semi-extensive, and intensive. In general, the pros for Artemia and cladocerans are that they are easier to culture than copepods. Copepods are often more difficult in term of culture requirements and feeding. Nevertheless, copepods have the advantage of being in either freshwater or saline water, whereas cladocerans are limited to freshwater and Artemia to seawater. Artemia cysts and copepod eggs have a well-defined protocol for storage and distribution to aquaculture end users. Cladocerans, however, have the potential for the ephippia stage, although this is not well developed. For toxicological testing, three species are used: Artemia franciscana, Daphnia magna, and Acartia tonsa, with Artemia and A. tonsa in seawater testing, D. magna in freshwater testing. The chapter concludes with a comparative analysis of these organisms from use and culturing capability and demonstrates that there are strong similarities and challenges across these taxa.

Full textAbstract:
Decapod Crustacea (shrimps, lobsters, and crabs) employ a range of different reproductive mechanisms that affect paternity, but does it include cryptic female choice (CFC)? This chapter focuses on events surrounding the fertilization of an egg by a sperm and the opportunities where cryptic fertilization bias might occur. It presents a new model of decapod fertilization, defined in terms of space and time to fertilization. Females have several ways to store sperm and influence fertilization outcomes, which should be affected by (1) their growth pattern (indeterminate or determinate), (2) the link between molting and mating (soft-shell or hard-shell mating), (3) fertilization latency, and (4) how sperm are protected (no protection or storage is separate from the oviduct, or storage in a seminal receptacle is linked to the oviduct). Paternity data available for 26 decapods show that in 85% of species, females carry broods with multiple paternity and 15% have broods with single paternity. Therefore many (if not most) females mate with several males and so they certainly could make a choice. However, whether this pattern is due to CFC or merely reflects mating history is a matter of debate. At present, there are no unequivocal data that demonstrate CFC: outcomes caused by male mate guarding and sperm competition cannot be distinguished from female choice. The challenge is to understand what females might be choosing and how to detect that choice. Detecting CFC in field data is difficult, if not impossible, because both single and multiple paternities could be favored.

IntechOpen, 2021. http://dx.doi.org/10.5772/intechopen.95591.
Full textAbstract:
In this chapter, a little of the history of Carmen City, Mexico is addressed; this island is immersed in a Protected Natural Area and in the “Campeche Sound” an oil extraction site. Fishing natural resources were for many years the pillar of the development of the area; the most commercially important species are still shrimp, oysters and scales. Nowadays, although the volumes of capture have decreased considerably, different species of high commercial value are still extracted. The considerable development of the oil industry has brought with its economic development and a better quality of life for its inhabitants; however, the ravages of pollution, rapid population growth, and deforestation have been the unwanted factor. This chapter addresses the effects of heavy metals on human health through a risk analysis, based on the criteria of the US Environmental Protection Agency (USEPA) that was carried out for different commercial species based on carcinogenic factors and not carcinogenic; the results show that the risk from consumption of these species is “potentially dangerous” for human health, especially in those species that, due to their eating habits (mollusks, bivalves, clams) tend to bio-accumulate heavy metals, such as cadmium, which it has been considered by the International Agency for Research on Cancer (IARC) as a risk factor; for this reason, the importance of periodically evaluating and monitoring oyster extraction banks, clams and, in general, all fishery products. Mexican legislation and various international legislations dictate the maximum permissible and tolerable levels of heavy metals in fishery products; the organisms considered in this study exceeded the permissible limits in copper and nickel, which represents a risk for human consumption.

Full textAbstract:
Infectious diseases are global and local. They impact health and disease in every country, but protean factors— cultural, geographical, and political— determine their particular local distribution. Every single patient is globally colonized by microorganisms, but singular behaviours, genetics and co- morbidities significantly determine what organisms cause disease in any individual. The practice of infectious diseases medicine necessarily demands an understanding of the person and the world in which they live. This chapter will emphasize the importance of context in assessing patients for infectious diseases. In terms of global mortality, communicable diseases remain the leading causes of mortality. Despite the evocative epithet of ‘infectious diseases’, these are not all caused by creatures that creep and crawl. Cosmopolitan diseases (i.e. universally distributed infections such as influenza or bacterial pneumonia) represent a huge burden wherever medicine is practised. However, it is important to note that in high- resource settings, infection imported by travel and migration is increasing. In particular, the international traffic of emerging infections, such as Zika virus, and anti-microbial resistance (AMR) are already major healthcare problems. As the world shrinks and the climate changes, the distribution of infectious diseases will continue to change. The threat of AMR no longer looms— it is a present and real danger. In the time it will take for disciples of this text to reach the end of their specialty training, AMR will account annually for more deaths than cancer. The delivery of almost all interventional, surgical, and immunomodulatory therapies depends on our ability to provide effective anti- microbial prophylaxis and rescue. The ability of organisms to adapt rapidly to novel iatrogenic selection pressures means that the treatment of human immunodeficiency virus (HIV), tuberculosis (TB), malaria, and manifold other pathogens will be compromised, not simply anti- bacterial agents. The future of modern medicine depends on the global healthcare community sharing both concern and responsibility. This chapter will include cases pertaining to the management of AMR.

Cement is a practical material for constructing the geological disposal system of radioactive wastes. However, such materials alter groundwater up to 13 in pH around the repository, changing the permeability of natural barrier. So far, the authors have examined the relation of permeability change with dissolution process by flowing a high pH solution (NaOH, 0.1 mM) into a bed packed with amorphous silica particles. Here, the particle diameters were adjusted to a size fraction of 74 to 149 μm by sieving. Its specific surface area was estimated as 350 m2/g by the BET method using nitrogen gas. The experimental results showed that the permeability did not immediately change although the soluble silicic acid continuously flowed out of the packed bed. This study proposes a new mathematical model considering the diffusion and dissolution processes in the inner pore of the particle. This model assumed that each packed particle (74 to 149μm in diameter) consists of the sphere-shaped aggregation of smaller particles (20 nm in diameter). OH− ions diffuse into the pore between such small particles, and simultaneously consumed by the reaction with small particles. The radius of the each packed particle (sphere-shaped aggregation of small particles) was defined by the length from the center of the aggregation to the region where the small particles still remains. Since the outer small particles more easily dissolve than inner small particles because of diffusion process of OH− ions, each packed particle gradually shrinks. The fundamental equations consist of a simple diffusion equation of spherical coordinates of OH− ions considering the reaction term, which is linked by the equation to describe the size change of small particles with time. Here, this model also considered a change (time and space) of the diffusion oefficient caused by the change of the porosity between small particles. Besides, the change of over-all permeability of the packed bed was evaluated by Kozeny-Carman equation and the calculated radii of packed particles. The dissolution rate constant already reported was used. The calculated result was able to well describe the experimental result, though there was no fitting parameter in the comparison with the experiment results. While the flow paths of underground cannot be simply simulated by a packed bed, this approach suggested that the dynamic behavior of permeability in a natural barrier depends also on non-uniformity of dissolution processes in inner pores (secondary pores) of minerals.

Today the United States is plagued by societal issues, economic insecurity, and increasing health problems. Societal issues include lack of community inclusion, pollution, and access to healthy foods. The high unemployment coupled with the rising cost of crude oil derivatives, and the growing general gap between cost of living and minimum wage levels contribute to a crippled consumer-driven US economy. Health concerns include increasing levels of obesity, cardiovascular disease, cancer, and diabetes. These epidemics lead to staggering economic burdens costing Americans hundreds of billions of dollars each year. It is well-known that many of the health issues impacting Americans can be directly linked to the production, availability, and quality of the food. Factors contributing to the availability of food include reduction of United States farmland, an increase in food imported from overseas, and the cost of goods to the consumer. The quality of food is influenced by the method of growth as well as imposed preservation techniques to support food transportation and distribution. At the same time, it has become increasingly common to implement biotechnology in genetically modified crops for direct human food or indirectly as a livestock feed for animals consumed by humans. Crops are also routinely dosed with pesticides and hormones in an attempt to increase productivity and revenue, with little consideration or understanding of the long term health effects. Research shows that community gardens positively impact local employment, community involvement and inclusivity, and the diets of not only those involved in food production, but all members of their households. The purpose of this work is to determine the feasibility of an energy efficient large-scale aquaponic food production and distribution facility which could directly mitigate growing socioeconomic concerns in the US through applied best practices in sustainability. Aquaponics is a symbiotic relationship between aquaculture and hydroponics, where fish and plants grow harmoniously. The energy efficient facility would be located in an urban area, and employ solar panels, natural lighting, rain water reclamation, and a floor plan optimized for maximum food yield and energy efficiency. Examples of potential crops include multiple species of berries, corn, leafy vegetables, tomatoes, peppers, squash, and carrots. Potential livestock include responsibly farmed tilapia, shrimp, crayfish, and oysters. The large scale aquaponic facility shows a lengthy period for financial return on investment whether traditional style construction of the building or a green construction style is used. However many forms of federal government aid and outside assistance exist for green construction to help drive down the risk in the higher initial investment which in the long run could end up being more profitable than going with a traditionally constructed building. Outside of financial return there are many proven, positive impacts that a large-scale aquaponic facility would have. Among these are greater social involvement and inclusivity, job creation, increased availability of fresh food, and strengthening of America’s agriculture infrastructure leading to increased American independence.

Full textAbstract:
Drilling fluid is the mixture of base fluid and special chemicals. The system is designed to meet operational requirements. These complex fluids can carry drilled cuttings to surface, provide enough force or pressure to the formation and have adequate holding capacity in pump-off period to prevent particle precipitation. These necessities are controlled by fluid rheology. The art of flow or flow science, i.e. rheology, examines the deformation and flow behavior of the fluid. Ideal viscous flow through ideal elastic deformation is analyzed in this branch. Increase in energy demand and depletion of shallow hydrocarbon reserves has driven the industry to explore deeper reservoirs. Thanks to the technical developments in the drilling industry, operations can go further, especially in offshore wells. Non-aqueous conventional drilling fluid systems (NAS), synthetic based mud (SBM) or oil based mud (OBM), are favorable due to lubricity effect, high inhibitive characteristic and temperature-rheological stability in deep formations. Despite the advantages of NAS over the water based systems (WBM), their flow characteristics vary with pressure due to compressibility. Mezger stated that “For most liquids, the viscosity values are increasing with increasing pressure since the amount of free volume within the internal structure is decreasing due to compression, therefore the molecules are more and more limited in their mobility. This increases the internal frictional forces and the flow resistance”1. By considering the primary well control requirements, drilling fluid equivalent pressure in both static and dynamic conditions can overbalance the fluid pressure in the rock pores and cannot exceed the inelastic strength of the medium in conventional, over-balanced operations. Mud playing pressure window shrinks as the depth is increased and is even not tolerable in ultra-deep offshore wells. Incompetent fluid formulation and hydraulic design led to detrimental and vital problems. In literature, limited research on high pressure fluid deformation behavior and rheological experimental data are found to understand the flow behavior and rheological changes in down hole conditions2. Generally rheological measurements are taken at the surface conditions and extrapolated to the down hole conditions that cause the perversity in real high pressure deformation behavior. This study is conducted to examine the high pressure effect on NAS rheology and to compare the experimental results to the conventional WBM. High Pressure, High Temperature (HPHT) Anton Paar MCR-302 compact rheometer (1,000 bar–14,500 psi, 300°C capacity) is preferred rather than using HPHT viscometers due to exact frictionless air bearings in the laboratory experiments. Controlled shear rate (CSR) and rate sweep test methodologies are used in the rheological tests. Tests are performed from ambient surface conditions to 12,000 psi pressure at constant temperature. To get a better understanding of flow properties and to have a more accurate hydraulic design, rheological characterization is simulated under in-situ conditions. Test results are analyzed to understand the compressibility and pressure effects on rheological parameters in constitutive equation (yield stress, apparent viscosity, and flow behavior index) and deformation behavior.
