Avoiding obstacles in Underwater Glider Path Planning

Underwater gliders are strongly influenced by ocean currents due to their low surge speed. Gliders may drift significantly from their expected trajectories, making path planning a real concern for this type of vehicle, as it may reduce the time taken to reach a given waypoint or save power. In such a dynamic environment it is not easy to find an optimal solution or any such requires large computational resources. In this paper, we present a path planning scheme for this kind of underwater vehicle combining a technique inspired by a variant of the A* algorithm with an optimization process revealing the physical vehicle motion pattern. This method models a glider affected by the ocean current speed and direction, and generates a path according to predefined objectives. The combination of these two techniques allows static or dynamic obstacle avoidance, frequently demanded in coastal environments, with land areas, strong currents, shipping routes, etc. The method can easily be configured and adapted to various optimization problems, including missions in different operational scenarios. This planner shows promising results in realistic simulations, including ocean currents that vary considerably in time, and provides a superior performance over other approaches that are compared in this paper.
Barriers to HIV testing in Guatemala: A Qualitative Study

Background: Early detection and treatment decreases HIV transmission rates and leads to risk reduction in those who are diagnosed. HIV-infected Guatemalans typically present with late-stage disease. Objective: We employed qualitative methods to explore barriers to HIV testing in Guatemala. Methods: In depth, qualitative interviews were conducted in an HIV testing and treatment facility in Guatemala City. These were analyzed using the methods of Grounded Theory. Results: Four major barriers impeded HIV testing in our subjects: psychological factors, stigma/discrimination, gender roles/machismo, and systemic barriers to care. Many of our patients’ fears were grounded in a reality of discrimination, while the systemic problems of the healthcare system reflected misunderstandings and fears on the part of healthcare workers. Discussion: Our findings are consonant with the international literature. Our narrative suggested potential interventions; presenting HIV testing as a way to “save one’s life” instead of an “automatic death sentence” might foster HIV testing and earlier diagnosis
On Generalized Minty and Stampacchia Vector Variational-Like Inequalities and Nonsmooth Vector Optimization Problem Involving Higher Order Strong Invexity

This paper deals with the relations between generalized Minty vector variational-like inequality problems, generalized Stampacchia vector variational-like inequality problems and a class of nonsmooth vector optimization problems by using the concept of an efficient minimizer of order m in terms of Clarke subdifferential. Furthermore, we consider weak formulations of considered generalized Minty and Stampacchia vector variational-like inequality problems and establish the relationship between the solution of these vector variationallike inequality problems and strict minimizer of order m of considered nonsmooth vector optimization problem. Moreover, we employ KKM-Fan theorem to establish some existence results for the solutions of the generalized Minty and Stampacchia vector variational-like inequality problems. The results of the paper extend and unify some earlier results of Bhatia (2008), Li & Yu (2017) and Upadhyay et al. (2017) to the nondifferentiable case as well as for a more general class of nonconvex functions.

Estimation of cracking , yield , and ultimate capacity of FRP-strengthened reinforced concrete and steel sections using wavelet transform

Damage detection is a topic of great importance for structural health monitoring. Many varieties of structural damage can be detected by examining changes in structural response in terms of stiffness. Wavelet transform is a powerful mathematical tool for the processing and time-frequency analysis of transient signals and has great potential to be used in structural damage detection. In FRP-strengthened reinforced concrete and steel sections, stiffness changes can be caused by cracking, yielding of steel components, crushing of concrete, or rupture of FRP panels. With the help of wavelet transform, it is possible to use the continuous measurements of the response to bend or torsional loading to estimate the capacity of the cross section corresponding to the stiffness changes. In this paper, bending of FRP-reinforced steel beams filled by concrete under bending and CFRP-reinforced concrete beams under pure torsion is evaluated. The results show that the location of the damage appears as perturbations in the diagram of discrete wavelet coefficients, which indicate the time of cracking, yielding of steel, crushing of concrete in the compression zone, and rupture of FRP. Therefore, a wavelet transform-based data processing procedure can be used to estimate the cracking and yielding capacities of the beams subjected to torsion, the yielding capacity of the steel and the ultimate capacity of the beams subjected to bending. The results demonstrate a high level of agreement between the estimates obtained from the discrete wavelet transform method and the examined experimental and numerical data.
Design and construction of an ultraviolet germicidal irradiation device for the inactivation of Staphylococcus aureus in kitchen utensils

Ultraviolet UV-C radiation has been used as a germicidal method for more than 100 years due to its effectiveness in the control of microorganisms. In some regions of Colombia, there are health problems because of the use of untreated water, which can contaminate food and kitchen utensils, putting human health at risk. The main purpose of this study was to design and construct a low-cost ultraviolet germicidal irradiation (UVGI) device for the inactivation of the bacterial strain Staphylococcus aureus in kitchen utensils. The UVGI device is a chamber built in acrylic, consisting of an 8-watt ultraviolet lamp with a peak emission wavelength of 253.7 nm. The simulation of the ultraviolet lamp control was carried out through Proteus 8, and the control system was implemented using the Arduino UNO R3 ATmega328P. It was found that the optimal radiation doses were 34.44, 311.8 and 603.6 J/cm2 to effectively inactivate the studied bacterium for more than 18 h. The constructed UVGI device is a viable solution to a public health problem that exists in some rural areas of Colombia.

ACID : TRANSLOCATION , METABOLISM AND EFFECTS ON PEEL QUALITY OF ' MARSH ' GRAPEFRUIT ( Citrus paradisi MACF . )

of Dissertation Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy GIBBERELLIC ACID: TRANSLOCATION, METABOLISM AND EFFECTS ON PEEL QUALITY OF 'MARSH' GRAPEFRUIT ( Citrus paradisi MACF.) By Louise Ferguson August 1984 Chairman: Dr. F. S. Davies Major Department: Horticultural Science Gibberellic acid maintains 'Marsh' grapefruit ( Citrus paradisi Macf.) peel quality by delaying senescent peel color development and loss of peel firmness. Combined with 2,4-dichlorophenoxyacetic acid (2,4-D), which prevents preharvest fruit drop, the two extend the grapefruit harvest season. It was not known if decreased irrigation affects this treatment. It also was not known if postharvest application of this treatment would produce the same effects. In addition, GA„ uptake, translocation and metabolism had not been examined. This dissertation was undertaken to answer these questions. 'Marsh' grapefruit on rough lemon ( Citrus jambhiri Lush.) rootstock received irrigated and unirrigated treatments . Half of each irrigation treatment received a GA„ and 2,4-D spray at colorbreak. Preharvest sprays of GA„ and 2,4-D extended the grapefruit harvest season by increasing fruit removal and rind puncture force, delaying development of senescent color, and decreasing late-season and
The Effect of Housing Subsidies on Housing Costs in Finland - A Methodology study

This thesis is a literature and methodology survey discussing and analyzing Finnish studies on the effect of housing subsidies on rent. The purpose of this thesis is to achieve a basic understanding of housing subsidies’ effect on rents, i.e. the incidence of housing subsidies and the methods with which the subject has been researched. The main studies discussed are by Lyytikäinen and Eerola (2019), Viren (2013) and Kangasharju (2010). I will also discuss some highly cited foreign studies for reference. Housing subsidies are the second largest income transfer in Finland, so it is very important to study the incidence of the subsidies. The purpose of the housing subsidies is to help low-income households with their housing costs by reducing their effective rents. If the subsidies raise rent level compared to a situation without the subsidies, then government resources are not correctly allocated. Currently there are relatively few studies on the subject. This is due to the complexity of subsidy programs and that they differ greatly between countries. The conclusion presented in this paper is that there is no clear consensus on housing subsidies’ effect on rents and that recent studies have yielded different results. More studies should thus be performed to gain better understanding of the allocation of government resources.

Isolation and characterization of p-Coumaric acid from Diospyros melanoxylon medicinal plant endemic to Western Ghats, India

Diospyros melanoxylon has been traditionally for the treatment of fistula, relieving arthritis, and skin care. The bark extracts of the plant have been investigated in terms of phytochemical and pharmacological potential, while the leaf extract has been untapped. The present study aimed to evaluate the methanol extract of D. melanoxylon (DMM) in terms of the antibacterial (P 20). The activity-guided repeated fractionation of the methanol extract using silica gel column chromatography yielded a single compound, which exhibited remarkable antioxidant activity. The physicochemical and spectroscopic analyses (UV, IR, 1 H NMR, 13 C NMR, and MS) indicated that the bioactive isolated compound was p-coumaric acid, the effect of which was on par with the standard antioxidant, antibacterial, and anti-inflammatory drugs. Conversely, the effects of the extract on these pharmacological attributes enhanced, confirming that the better activity observed in the study was mainly due to the synergistic effects exerted by various compounds in the extract. In-silico studies have also confirmed the potential of the compound in these effective antibacterial properties. Therefore, the D. melanoxylon extract is a strong therapeutic agent with pharmacological potential.

Glutathione peroxidase in ovarian cancer patients in Indonesia

Background. Glutathione peroxidase (GPx) is one of the antioxidant enzymes that maintain the balance of reactive oxygen species. GPx has a notable role in the progression of cancer, including ovarian cancer. Synthesis of this enzyme may be down-regulated in cases of ovarian cancer. As far as we are aware, this has not been studied in an Indonesian population. Objective. To identify the difference in serum GPx levels between ovarian cancer patients and healthy controls. Methods. This was an observational analytical study with a case–control design. The study was conducted in the Department of Obstetrics and Gynaecology at the Haji Adam Malik Hospital in Medan, Indonesia. Serum GPx levels were measured in 20 ovarian cancer patients and 20 control subjects. Results. The types of ovarian cancer identified by histopathology in this study included serous adenocarcinoma (n=10; 50%) and various non-serous adenocarcinomas (50%). The mean (SD) serum GPx level was significantly lower in the cancer group (295.235 (244.479) mU/mL) than in the control group (743.546 (131.949) mU/mL) (p<0.0008). The median serum GPx level was lower among patients with serous ovarian cancer (209.915 mU/mL) than among those with non-serous ovarian cancer (338.885 mU/mL), although the difference was not statistically significant (p>0.226). Conclusion. Serum GPx levels were found to be significantly lower in patients with ovarian cancer than in healthy controls. Further studies are needed to determine an appropriate cut-off level for serum GPx in ovarian cancer in this population.
EFFECTIVE REMOVAL OF CHROMIUM BY STEEL SLAG

In the present study the adsorption studies were carried out for hexavalent chromium using alkali activated induction furnace slag. The induction furnace slag rich in iron content is not used in the steel production and is a land filling. Hexavalent chromium a major source in the effluents of tannery industry is set to cause major pollution to the soil, mankind and the environment. The alkali activation was carried out using 0.01N Sodium Hydroxide and 0.05N of K2Cr2O7. Continuous column studies were carried out at various bed height of steel slag from 5-50 cm. In this we have observed that decrease in concentration of chromium (VI) and cluster ion formation. Induction furnace steel slag was characterized using XRF and the adsorption studies were characterized using UV-visible spectroscopy , UVDRS, FT-IR, FESEM, ICP-MS and EDX analysis. The cost effective technology will be helpful in reducing the hexavalent chromium toxicity in the environment.
Proposal / Letter of Intent / Addendum ... ] to the ISOLDE and Neutron Time-of-Flight Committee / / Proposals for ISOLDE low-energy experiments Study of Interaction of 8 He with 209 Bi sub-barrier energy May 29 wednesday

Excitation functions for evaporation residues in the reaction 209 Bi( 8 He, xn) 217-xn At are proposed for measurement at the ISOLDE facility. A coincidence between neutron and alpha particles allows to get on break-upfusion and direct breakup phenomena of 8 He. Study of Interaction of 8 He with 209 Bi sub-barrier energy 1. Motivation It has been found long ago that the fusion of stable nuclei at energies close to the Coulomb barrier strongly depends on the coupling with other reaction channels, in particular with direct reactions [1, 2]. In the case of some light neutron-rich nuclei an extended distribution of nuclear matter is observed and the presence of valence neutrons can lead to the formation of a neutron halo or skin, characterized by small separation energy of the constituent nucleons, 6, 8 He are such examples. The reactions with halo nuclei have aroused much interest and continue to be a challenge both to experiment and theory. In particular, much effort has been devoted to studying near-barrier fusion of light weakly bound nuclei. What concerns the interaction of the neutron-rich nuclei 6,8 He with stable targets, one can expect increased fusion crosssection due to the reduction of the reaction Coulomb barrier because of the larger radius. On the other hand, the weak binding of the halo neutrons leads to a higher breakup probability of the nuclei which, in turn, reduces the fusion cross-section. If breakup occurs, consequent capture of the residual nucleus (the core) by the target nucleus or transfer of nucleons without any further interaction between the nuclei can take place. The exchange of one or several nucleons between the target and projectile, inelastic scattering, etc. are also probable. However, if the couplings between fusion and transfer reactions with positive Q-values are taken into account, it is expected that the fusion involving 6 He will be enhanced [3,4] similarly to the cases observed for stable beams [1, 2, 5]. In any case, the variety of processes makes it difficult to analyze the
IDENTIFICATION OF GENETIC IMPROVEMENT USING GENETIC MARKERS IN SOME LOCAL RABBIT STRAINS: 1. EFFECT OF GENETIC VARIATION

Genetic variations were detected in four rabbit genotypes; APRI line, New-Zealand White (NZW), Baladi Black (BB) and Gabali (GAB) breeds. Blood samples were taken from ten doe rabbits from APRI, NZW and BB in addition to seven does from GAB. Isozymes (esterase and peroxidase) and SDS-protein markers were used to detect the genetic variations within the four genotypes. RAPD-PCR analysis using six random arbitrary primers were employed to assess the genetic variations and phylogenetic relationships among the four genotypes. Results showed that there are a variation in both of protein and isozymes activity levels. Esterase profiles showed higher percentage of polymorphism (67.21%) than peroxidase (34.78%) and SDS-protein profiles (39.11%) within the studied genotypes. Overall mean of the genetic similarity within the studied genotypes based on all biochemical markers were 0.81 (APRI), 0.91 (NZW), 0.89 (BB) and 0.86 (GAB), which indicated high homogeneity within each genotype. The polymorphism percentage based on overall RAPD primers was 35.44% among the four genotypes, which suggest a kind of genetic diversity among the rabbit genotypes. From the dendrogram tree, both BB and GAB appeared to be closely related, while the APRI was the most different. The obtained results could have a great impact in rabbit breeding programs, such as selection or crossing programs.
Mycosporine-like Amino Acids and Antioxidative Enzymes Activity in Acytonema SP. under Cumulative Stress of UV Radiation and Salinity

207 DOI: http://dx.doi. org/10.37398/JSR.2020. 640130 Abstract: We have studied the cumulative effects of ultraviolet radiation (UVR), photosynthetically active radiation (PAR), and varying concentrations of NaCl (50, 150 and 200 mM) on the induction of mycosporine-like amino acids (MAAs) and antioxidative enzymes namely, ascorbate peroxidase (APX), catalase (CAT) and superoxide dismutase (SOD) in a cyanobacterium Scytonema sp. isolated from agricultural field of Maunath Bhanjan, India. Spectroscopic analysis and high performance liquid chromatography (HPLC) revealed the presence of a single MAA (λmax=332 nm) at a retention time of 3.22 min. Based on the UV-VIS absorption spectrum, HPLC and mass spectrometry analyses, the MAA was identified as shinorine (λmax334, m/z: 333). Maximum induction of shinorine was observed in PAR+UV-A+UV-B treated samples having 200 mM of NaCl after 60 h of treatment. Production of antioxidative enzymes increased after PAR, PAR+UV-A and PAR+UV-A+UV-B treatments and highest level of production occurred in the cultures having 200 mM concentration of NaCl. These findings suggest that Scytonema sp. could serve as a suitable strain for bioremediation of saline environments and production of value added compound such as MAAs.
Error by omitted variables in regret-based choice models: formal and empirical comparison with utility-based models using orthogonal design data

Random regret minimization models have mostly relied on the assumption of identically and independently distributed error terms. Professionally designed stated choice experiments use various design and implementation principles to ensure that any errors meet this assumption. Based on the behavioral theory that individuals arrive at a decision by first processing the attribute values of a choice alternative according to an integration rule to derive the stochastic utility associated with the choice alternatives and then apply the deterministic utility maximizing rule, this assumption can be reasonable met for utility maximizing models. The question is whether this assumption is equally defendable for random regret minimization models in light of the difference in model specification, rooted in fundamental behavioral differences between the underlying decision theories. This study focuses on the effect of omitted variables which is one of main sources of error. Based on a formal analysis and empirical comparison, we argue and show that omitted variables cause correlation between unobserved regrets. Consequently, the independence assumption is difficult to defend because the omitted variables simultaneously affect the comparison of choice alternatives. To capture this effect, we propose an error components structure for regret-based choice models. Empirical results obtained for classic random regret-minimization models for two different data sets support our theoretical arguments. If these results can be generalized to other data sets, it is advisable to adopt an error components structure when estimating these classic random regret-minimization models unless one has reason to believe the effect of the omitted variables is small and therefore can be ignored.
