Abstract:
The project titled "Image Steganography using Mid-Point Transformation Technique" aims to explore and implement a novel approach to concealing information within digital images while preserving their visual integrity. Steganography is an age-old technique for covert communication, and this project leverages the mid-point transformation method to embed data seamlessly into images. The mid-point transformation technique involves the subtle alteration of pixel values based on the midpoint of neighboring pixels. This process ensures that the changes made to the image are imperceptible to the human eye, allowing for effective data hiding without compromising the overall visual quality. The project will focus on the development of an algorithm to encode and decode hidden information within images using the mid-point transformation technique. Implementation will be carried out using a programming language suitable for image processing, and the project aims to provide a user-friendly interface for ease of use. Key objectives include understanding the theoretical foundations of steganography, implementing the mid-point transformation algorithm, evaluating the effectiveness of the technique in terms of data capacity and visual impact, and comparing the results with existing steganographic methods. Key Words: Image Steganography, Mid Point Transformation, Steganography Techniques, Digital Image Security, Data Hiding, Information Security.

Abstract:
The main motivation for this work lies in the construction of new and efficient methods to improve the efficiency index of ‘Mid-Point Derivative Based Closed Newton-Cotes Quadrature Rules’. Proposed methods use the derivative values at the mid-points in each strip of integrations such as Mid-Point Derivative Based Closed Trapezoidal, Simpson One Third, Simpson Three eight and Bool’s Rule. The degree of precision and order of accuracy of proposed methods are higher than all the existing methods. Furthermore, error terms of the proposed methods are calculated by using the concept of precision. An extensive comparison of the proposed formulas, classical and mid-point quadrature rules for the number of function evaluation, error terms, coefficient of error terms and results obtained from some different problems are given. The comparisons illustrate that the new proposed Closed Newton-Cotes Rules are much superior to Classical Rules and Zhao and Li’s ‘Mid-Point Derivative Based Closed Newton-Cotes Quadrature’ schemes.

Abstract:
Objectives: This study investigates coincidence of the most-prominent point and the mid-point on upper anterior teeth in relation to the use of straight-wire appliances. Materials and Methods: Alginate impressions of the upper jaw were obtained from forty Caucasian patients. Impressions were cast using hard dental stone. The teeth on each upper study model (canine to canine) were marked along the facial axis of the clinical crown (FACC line) then separated using a very thin diamond disc. Each tooth was mounted on a glass slide using sticky wax and cut into two halves down this FACC line. Images were acquired of the sections and a straight line connecting the gingival margin and the incisal edge was drawn on the flat cut surfaces (now the proximal crosssectional view). From this line, perpendicular lines were drawn at the mid-point and most prominent point to the labial curve. Coincidence rate was calculated or whether the most prominent point was gingival or incisal to the mid-point. Results: Approximately 80% of upper central incisors had coincident mid- and most-prominent points. Upper lateral incisors and canine teeth had approximately 50% coincidence. The vast majority of cases without coincidence showed the most-prominent point incisal to the mid-point for all tooth kinds with just 5% or less gingival. Conclusions: The high proportions of non-coincident examples found suggest that clinicians should be aware of individual variation and that this may possibly effect 3rd order alignment.

Abstract:
In order to ensure the safe and reliable operation of a high-speed railway, the precise positioning of the mid-point anchor in the catenary is very important. In view of the two problems in the calculation of the mid-point anchor position of the catenary in a long ramp section, the calculation accuracy is low, and the calculation of the central anchor clamp position is lacking. In this study, the predetermined location of the mid-point anchor is chosen based on the mid-point anchor location principle and the line condition, and the range of the allowable error of the mid-point anchor setting is determined according to the predetermined position of the mid-point anchor. Secondly, by considering the impact of the line ramp and using the measured span length, the tension difference of the clue in the direction of the line is calculated. Then, the theoretical location of the mid-point anchor clamp is determined using the downhill component and the tension difference. Finally, the theoretical position of the clamp is corrected according to the setting of the dropper to obtain the corrected position of the clamp. An FEM (finite element method) of the catenary is established in ANSYS software to calculate the height difference between the messenger cable and the contact wire at the point of the mid-point anchor setting, and then the length of the mid-point anchor rope is obtained. Through the calculation of actual case data, the maximum value of the relative error of the location of the mid-point anchor obtained by this proposed method is very small compared with the actual position, which verifies the effectiveness of this method.

Abstract:
Abstract Three-level inverters are among the best options for high voltage and high-power applications because of their high capacity, high rated voltage, low harmonic content of the output current, and minimal switching losses. However, the issue with mid-point voltage balancing is an inherent drawback of three-level inverters. The unbalanced mid-point voltage of a three-level inverter leads to low harmonics in the output voltage, causing voltage distortion and seriously reducing the power quality. The unbalanced mid-point voltage also puts more voltage strain on the DC bus side and power switching tubes. As a result, this paper analyzes the remedies for NPC-type three-level inverters’ fluctuating neutral potential and offers hardware and software solutions to regulate the potential neutral balance. It outlines the two primary mid-point potential control strategies depending on the SVPWM and SPWM strategies, provides a detailed study of the software approach, and briefly examines the DMWPWM strategy’s best solution. There are several potential applications for the mid-point potential balancing control method. It may significantly enhance the power quality of rectifiers and inverters and has considerable advantages for real-world uses like solar and wind energy production.

AbstractObjectiveTo determine cochlear duct mid-scalar length in normal cochleae and its role in selecting the correct peri-modiolar and mid-scalar implant length.MethodsThe study included 40 patients with chronic otitis media who underwent high-resolution computed tomography of the temporal bone. The length and height of the basal turn, mid-modiolar height of the cochlea, mid-scalar and lateral wall length of the cochlear duct, and the ‘X’ line (the largest distance from mid-point of the round window to the mid-scalar point of the cochlear canal) were measured.ResultsCochlear duct lateral wall length (28.88 mm) was higher than cochlear duct mid-scalar length (20.08 mm) (p < 0.001). The simple linear regression equation for estimating complete cochlear duct length was: cochlear duct length = 0.2 + 2.85 × X line.ConclusionUsing the mid-scalar point as the reference point (rather than the lateral wall) for measuring cochlear duct mid-scalar length, when deciding on the length of mid-scalar or peri-modiolar electrode, increases measurement accuracy. Mean cochlear duct mid-scalar length was compatible with peri-modiolar and mid-scalar implant lengths. The measurement method described herein may be useful for pre-operative peri-modiolar or mid-scalar implant selection.

Abstract:
There has been an increasing interest in survival analysis with interval-censored data, where the event of interest (such as infection with a disease) is not observed exactly but only known to happen between two examination times. However, because so much research has been focused on right-censored data, so many statistical tests and techniques are available for right-censoring methods, hence interval-censoring methods are not as abundant as those for right-censored data. In this study, right-censoring methods are used to fit a proportional hazards model to some interval-censored data. Transformation of the interval-censored observations was done using a method called mid-point imputation, a method which assumes that an event occurs at some midpoint of its recorded interval. Results obtained gave conservative regression estimates but a comparison with the conventional methods showed that the estimates were not significantly different. However, the censoring mechanism and interval lengths should be given serious consideration before deciding on using mid-point imputation on interval-censored data.

Abstract:
This thesis details the geomorphology and timing of the mid-Holocene fossil reef at Cleveland Point, Moreton Bay, Queensland. This research presents the first subsurface data from percussion cores through the reef. Results reveal that Cleveland Point reef initiated quickly after rising seas flooded their foundations 7300 years ago. The reef remained in a "catch-up" growth mode from 7300 to 5700 years ago before reef accretion ceased. Age data suggests that the termination of the reef occurred 5700 years ago and coincided with a hypothesized lowering of sea-level and a possible change in terrigenous sediment distribution in Moreton Bay.

Abstract:
Several fringing coral reefs in Moreton Bay, Southeast Queensland, some 300 km south of the Great Barrier Reef (GBR), are set in a relatively high latitude, estuarine environment that is considered marginal for coral growth. Previous work indicated that these marginal reefs, as with many fringing reefs of the inner GBR, ceased accreting in the mid-Holocene. This research presents for the first time data from the subsurface profile of the mid-Holocene fossil reef at Wellington Point comprising U/Th dates of in situ and framework corals, and trace element analysis from the age constrained carbonate fragments. Based on trace element proxies the palaeo-water quality during reef accretion was reconstructed. Results demonstrate that the reef initiated more than 7,000 yr BP during the post glacial transgression, and the initiation progressed to the west as sea level rose. In situ micro-atolls indicate that sea level was at least 1 m above present mean sea level by 6,680 years ago. The reef remained in "catch-up" mode, with a seaward sloping upper surface, until it stopped aggrading abruptly at ca 6,000 yr BP; no lateral progradation occurred. Changes in sediment composition encountered in the cores suggest that after the laterite substrate was covered by the reef, most of the sediment was produced by the carbonate factory with minimal terrigenous influence. Rare earth element, Y and Ba proxies indicate that water quality during reef accretion was similar to oceanic waters, considered suitable for coral growth. A slight decline in water quality on the basis of increased Ba in the later stages of growth may be related to increased riverine input and partial closing up of the bay due to either tidal delta progradation, climatic change and/or slight sea level fall. The age data suggest that termination of reef growth coincided with a slight lowering of sea level, activation of ENSO and consequent increase in seasonality, lowering of temperatures and the constrictions to oceanic flushing. At the cessation of reef accretion the environmental conditions in the western Moreton Bay were changing from open marine to estuarine. The living coral community appears to be similar to the fossil community, but without the branching Acropora spp. that were more common in the fossil reef. In this marginal setting coral growth periods do not always correspond to periods of reef accretion due to insufficient coral abundance. Due to several environmental constraints modern coral growth is insufficient for reef growth. Based on these findings Moreton Bay may be unsuitable as a long term coral refuge for most species currently living in the GBR.

Abstract:
Water is a valuable and crucial resource, the protection of which poses environmental, social and economic challenges. Fundamental to the sustainable use of water is effective management. In the Canterbury region of New Zealand, nitrate contamination has become a resource management issue due to changes in land use and intensification, which have placed pressure on the region’s groundwater and surface water systems. The purpose of this study was to assess and track nitrate concentrations on the Central Canterbury Plains with specific emphasis on a local point source of nitrate, the Ashburton Meat Processors plant. To make this assessment review of historical data was followed by the collection of 131 groundwater and 25 surface water samples to analyse the geochemical properties of the water and the stable isotopic composition of nitrate in the water. It was hypothesised that nitrate concentrations at a regional scale have increased since regular records began and that the stable isotopic composition of different nitrate sources are not discernable. Nitrate concentrations across the Canterbury region were found to have increased, prompting concerns about water quality. Concentrations are elevated above natural background levels across much of the Canterbury Plains and extreme concentrations are associated with local point sources of nitrate. Nitrate concentrations down gradient of the Ashburton Meat Processing plant are shown to have declined approximately 5% per year for the past ten years, which is in contrast to the rest of the region, where average concentrations have nearly doubled in 20 years. The reduction of contamination from the point source is most likely the result of the implementation of better wastewater management practices in the early 21st century. The δ18O and δ15N values of nitrate were found to be relatively homogenous over the Canterbury Plains. Therefore, it is suggested by this study that the dual-isotope approach alone, is not a viable tool for nitrate source identification in the region. The uniform nitrate stable isotopic composition in Canterbury could be attributed to a single, principle source of nitrate, such as clover, that overprints other isotopic compositions of nitrate source, or may also be the result of soil processes and the farming techniques used in the region. This research presents important findings for the future of identifying and managing nitrate sources in the Canterbury region. Better management practices are required for the diffuse source(s) of nitrate contributing to the widespread contamination. Critical thinking and the willingness of stakeholders to engage in the identifying, documenting and solving problems is necessary to ensure the effective management and sustainability of this precious resource.

Abstract:
Le segment 16°N de la dorsale Est-Pacifique (EPR) interagit avec le point chaud des Mathématiciens (PCM). A partir de l’analyse géochimique de 120 échantillons de verres basaltiques prélevés par submersible Nautile (campagne à la mer PARISUB 2010) coulée par coulée, ce travail présente une étude à très petite échelle de l’hétérogénéité chimique du manteau sous quelques kilomètres de dorsale (15°37’N et 15°47’N). Les résultats obtenus témoignent d’une variabilité géochimique jamais observée à si petite échelle sous une dorsale. Le degré d’hétérogénéité du manteau dans cette zone est comparable à celui de l’ensemble de l’EPR. Cette diversité est le produit du mélange entre trois sources mantelliques principales, caractérisant l’influence et l’hétérogénéité du point chaud. La densité de l’échantillonnage offre une résolution spatiale en adéquation avec les données bathymétriques, ce qui a permis de coupler les deux approches et faire une reconstruction spatio-temporelle de l’évolution géochimique et morphologique du système EPR/PCM.Celle-ci commence il y a environ 600 ka par le gonflement du segment et un changement général dans la composition du manteau ambiant, suivi de deux sauts d’axe successifs en direction de la chaîne il y a 250 et 150 ka. Lors de cette phase de rapprochement de nouvelles signatures géochimiques émergent ponctuellement dans les MORB. Parmi elles,une signature relique de manteau appauvri régional, une autre d’hétérogénéité enrichie locale, et enfin celle de deux types d’hétérogénéités contenues dans la source du PCM.Cette dernière, n’apparaît dans les MORB qu’au cours des 100 dernières années autour de 15°44’N, et constitue une signature géochimique inédite pour des MORB. Ce nouveau composant a la particularité d’avoir du Pb très peu radiogénique ("Unradiogenic Lead Component", ULC) associé à des signatures isotopiques en Sr, Nd et Hf enrichies.Les compositions en éléments majeurs, traces et isotopes (Sr, Nd, Hf, Pb et He) suggèrent l’implication de matériel métagabbroique, ancien (&gt;2Ga) à affinité continentale.La présence de sulfures dans la source permettrait d’expliquer le Pb peu radiogénique.Le recyclage dans le manteau supérieur de pyroxénites à sulfures, provenant de la partie profonde d’anciens arcs continentaux permettrait d’expliquer l’origine de ULC. Les basaltes ULC seraient donc les témoins volcaniques de la fusion de ce réservoir discret qui contribue à résoudre le paradoxe du Pb<br>120 Mid-Ocean-Ridge basaltic (MORB) glasses were collected on discrete lava flow (~200m sampling interval) during submersible dives along the East-Pacific-Rise (EPR), between 15°37’N and 14°47’N, precisely where the ridge intersects the Mathematicianshotspot track. The data display a geochemical variability that has never been observedalong a ridge at such a small spatial scale. The range of isotopic compositions along this 15 km segment is commensurable to that of the entire EPR. It can be accounted for by a mixture of three main components, representative of the hotspot heterogeneity.The dense sampling, along and across the ridge segment, matches the resolution of themicro-bathymetric data, which made the spatio-temporal reconstruction of the geochemical and morphological evolution of the EPR/Mathematician hotspot system possible.The latest starts 600 kya with the segment inflation and a global change in the ambient mantle composition, followed by two successive jumps of the ridge axis (250 and 150 kya) towards the seamounts chain. During this phase as the two systems are getting closer,new geochemical signatures emerge in MORB. Among them, relics of regional depleted mantle, small enriched local heterogeneities, and two types of heterogeneities belonging to the hotspot source. The last one become apparent only during the last 100 yearsaround 15°44’N, and constitutes a novel geochemical signature for MORB. This new component’s most noticeable property is its very unradiogenic Pb ("Unradiogenic Lead Component", ULC) associated with mostly enriched Sr, Nd and Hf isotopic signatures. Putted together, major, trace elements and isotopes (Sr, Nd, Hf, Pb and He) suggest anancient (&gt;2Ga) lower continental metagabbroic origin for this material, while the involvement of sulfides is considered in order to explain the unradiogenic lead compositions. Overall, the preferred model for the formation of ULC is the recycling within the uppermantle of sulfide bearing pyroxenites coming from continental arc roots. ULC-influenced basalts represent magmatic witnesses of the melting of this cryptic reservoir that can contribute to solve the Pb paradox

Full text
Abstract:
Numerous well-preserved, exhumed paleochannels in the Morrison, Cedar Mountain and Dakota Sandstone formations are exposed east of Castle Dale, Utah. These channels consist primarily of point bar complexes and scattered, low sinuosity channels. To determine the vertical and lateral relationships of these channels within the Cedar Mountain and Dakota Sandstone formations, a 1:24,000 scale geologic map covering ~140 km2 was created showing the fluvial sandstones. In the study area the Cedar Mountain Formation consists, from bottom to top, of 2.5-10 m of Buckhorn Conglomerate Member equivalent units, ~80 m of the Ruby Ranch Member, and ~30 m of the Mussentuchit Member. The Dakota Sandstone consists of conglomeratic to sandy, meandering channel fills within the Mussentuchit Member. The Ruby Ranch-Mussentuchit member contact is diagnosed as the top of a laterally extensive, ~10 meter thick, maroon paleosol with calcrete horizons and root traces. When deeply weathered the contact is discernable as a shift from maroon mudstone to a pale green-white, silty mudstone. Like the balance of the Mussentuchit Member overbank deposits, the white-green mudstone is rich in smectitic clays. In the southern one-third of the mapped area, Ruby Ranch Member sandstones are thin, discontinuous channel segments surrounded by floodplain deposits. In the middle to northern area, point bar complexes dominate, some of which are laterally amalgamated. Flow direction data from four meander complexes and a low sinuosity channel indicate an average northeast flow. Dakota Sandstone channels all of which are within the Mussentuchit Member also flowed to the northeast but point bar complexes are both more numerous and more laterally continuous than in the Ruby Ranch Member, indicating deposition in an area with less accommodation space than during Ruby Ranch Member time. The data indicate the Dakota Sandstone consists exclusively of fluvial sandstones encased within the Mussentuchit Member of the Cedar Mountain Formation. Therefore, these units are coeval and simply different facies of the same depositional system. Consequently the Mussentuchit Member is considered a member facies of the Dakota Formation.

Abstract:
O biodiesel tem sido amplamente utilizado como uma fonte de energia renovável, que contribui para a diminuição de demanda por diesel mineral. Portanto, existem várias propriedades que devem ser monitoradas, a fim de produzir e distribuir biodiesel com a qualidade exigida. Neste trabalho, as propriedades físicas do biodiesel, tais como massa específica, índice de refração e ponto de entupimento de filtro a frio foram medidas e associadas a espectrometria no infravermelho próximo (NIR) e espectrometria no infravermelho médio (Mid-IR) utilizando ferramentas quimiométricas. Os métodos de regressão por mínimos quadrados parciais (PLS), regressão de mínimos quadrados parciais por intervalos (iPLS), e regressão por máquinas de vetor de suporte (SVM) com seleção de variáveis por Algoritmo Genético (GA) foram utilizadas para modelar as propriedades mencionadas. As amostras de biodiesel foram sintetizadas a partir de diferentes fontes, tais como canola, girassol, milho e soja. Amostras adicionais de biodiesel foram adquiridas de um fornecedor da região sul do Brasil. Em primeiro lugar, o pré-processamento de correção de linha de base foi usado para normalizar os dados espectrais de NIR, seguidos de outros tipos de pré-processamentos que foram aplicados, tais como centralização dos dados na média, 1 derivada e variação de padrão normal. O melhor resultado para a previsão do ponto de entupimento de filtro a frio foi utilizando os espectros de Mid-IR e o método de regressão GA-SVM, com alto coeficiente de determinação da previsão, R2Pred=0,96 e baixo valor da Raiz Quadrada do Erro Médio Quadrático da previsão, RMSEP (C)= 0,6.

Therefore, there are several properties that must be monitored in order to produce and distribute biodiesel with the required quality. In this work, the biodiesel physical properties such as specific mass, refractive index and cold filter plugging point were measured and associated with near infrared spectroscopy (NIR) and mid-Infrared spectroscopy (mid-IR) spectra using chemometric tools. The Partial Least Squares Regression (PLS), Interval Partial Least Squares Regression (iPLS), and Support Vector Machines Regression (SVM) with variable selection by Genetic Algorithm (GA) methods were used to model the aforementioned properties. The biodiesel samples were synthesized from different sources such as canola, sunflower, corn, and soybean. Additional biodiesel samples were purchased from a Brazil South Region supplier. Firstly, the preprocessing baseline correction was used to normalize the NIR spectral data, following others preprocessing types were applied in such as the mean center, the first derivative and standard normal variate. The best result for predicting the cold filter plugging point was using Mid-IR spectra and GA-SVM regression method, with high coefficient determination of prediction, R2Pred = 0.94 and low value of the Root Mean Square Error of Prediction, RMSEP (C) = 0.7. For the specific mass prediction model, the best result was obtained using the Mid-IR spectrums and PLS regression, with the R2Pred = 0.98 and RMSEP (g/cm3) = 0.0002. As for a prediction model for the refractive index, the best result was obtained using the Mid-IR spectrums and PLS regression, with the R2Pred = 0.98 and RMSEP = 0.0001. For these datasets, the PLS and SVM models demonstrated theirs robustness, presenting themselves as useful tools for the biodiesel properties prediction studied

Abstract:
The flow near a stagnation-point is a fundamental topic in fluid dynamics and it has been studied by several researches during the past decades because of its relevant applications. In this Thesis we investigate the influence of the electromagnetic field on the stagnation-point flow of a Newtonian or a micropolar fluid. To this end we consider three types of such a motion: plane orthogonal, plane oblique and three-dimensional. We take into consideration a fluid which moves towards a flat surface. We descrive several situations which are relevant from a physical point of view when an external uniform or not uniform electromagnetic field is impressed. Actually, we have prove that if the external magnetic field is uniform and the induced magnetic field is neglected, then the stagnation-point flow exists if, and only, if the external magnetic field has some suitable directions. Further, we compute the induced magnetic field in the other cases. We prove also that if the external magnetic field is not uniform and it is parallel to the velocity at infinity then the three-dimensional stagnation-point flow is possible if and only if it is axisymmetric. In all the cases here considered, the MHD PDEs which govern the motion are reduced to a system of nonlinear ODEs. These boundary values problems are then integrated numerically and some graphics and tables are furnished in order to show the behaviour of the solution near the obstacle.

Abstract:
The year 2024 is characterized by an explosive political context, shattering the electoral unity of today's two main political families, the Marcos and the Duterte. War has broken out between the two clans, as the Marcos Jr. administration faces key mid-term elections in May 2025. Although macro-economic results are considered satisfactory, the population is still not seeing the benefits, and is even tending to become poorer. On the other hand, important structural reforms, such as the modernization of public transport and the divorce law, have been delayed by electoral deadlines. One of the points of profound divergence between the Marcos and Duterte administrations is the Philippines' diplomatic and military positioning vis-à-vis the United States and China. On this point, the year 2024 is marked by numerous tensions between China and the Philippines in the South China Sea, and by a deepening of ties between the Philippines, the United States and their allies.

Abstract:
Owing to the recent technological advances in mid-infrared (3-20 μm; MIR) laser technology, especially cascade laser spectroscopy (CSL) has evolved into a state-of-the-art tool for the selective and sensitive quantification of trace analytes in liquid, solid, and gaseous state in a wide variety of sensing scenarios. High output power, narrow linewidths, single-mode operation, low power consumption, broad tunability and compact dimensions are just some of the most outstanding features of cascade lasers. Since their introduction in the mid 1990ies, quantum cascade lasers (QCL) and interband cascade lasers (ICL) have rapidly matured into the probably most important contemporary MIR laser light sources. In this presentation, we will discuss state-of-the-art sensing platforms that benefit from cascade lasers combined with miniaturized photonic platforms providing direct access to molecule- specific information. Indeed, point-of-care diagnostics in clinical settings are becoming more prevalent taking advantage of the fact that MIR detection schemes do not require reagents or labeled constituents, and therefore facilitate localized on-site analysis close to real-time. With increasing progress towards highly miniaturized MIR optical components, evidently devices useful in medical/clinical applications may directly capitalize on advantageous features of integrated MIR photonics. Quo vadis? For sure, in- vivo applications enabling direct sensing and/or condition monitoring within living organisms are considered the ‘holy grail’. We will highlight the utility of MIR catheter technology for analyzing cartilage damage in-vivo during arthroscopic surgery, and discuss potential and challenges when translating this technology into clinical practice.

Abstract:
A Maximum Power Point Tracking or Tracker (MPPT) is a high efficiency system that extracts the maximum power output from a solar cell or an array of photovoltaic (PV) cells. Normally the solar power systems efficiency is less. To improve its efficiency, solar power systems are usually equipped with the function of MPPT. The work presented in this paper concerns the designing and implementation of a photovoltaic system (PV) provided with an MPPT control. More particularly, the utilization of a buck converter for controlling photovoltaic power using Maximum Power Point Tracking (MPPT) mechanism was presented. First the photovoltaic module is analyzed using SIMULINK software. In this project the buck converter was used along with a MPPT control. The MPPT is responsible for extracting the maximum possible power from the photovoltaic and feed it to the load via the buck converter which steps down the voltage to the required magnitude. The algorithm utilized for MPPT was the three-point weighting that incorporates mid-point tracking. The system was designed and simulated in MATLAB. Both the buck converter and the solar cell are modelled using Sim- Power Systems blocks. Especially, the waveforms of MPPT and Photo voltaic have been presented.

Full text
Abstract:
Northwestern pond turtles have gained much attention in the past few decades due to dramatic population declines. We compiled data on the pond turtle?s historic occurrence within northern Golden Gate National Recreation Area (GOGA) and Point Reyes National Seashore (PORE), including recent incidental observations by U.S. Geological Survey (USGS) staff. To build on that past data and better understand current pond turtle distribution, abundance, non-native co-inhabitants, demographics, nesting behavior, and nest site characteristics, we conducted distribution surveys here from 2015?2019. We found northwestern pond turtles using visual encounter and trapping surveys at 11 sites, mostly confirming past USGS observations at those sites. However, we detected pond turtles in only 38% of sites previously identified by USGS as having pond turtles. In our surveys, pond turtles were most abundant at two Martinelli ponds along the southeastern slopes of Tomales Bay. At this location, we have an estimated population size of 94 adults (carapace length range from 68 to 300) from mark-recapture trapping surveys. This site is also the largest nesting population in the park, with annual nest abundance of 13.75 nests per year and a mean clutch size of 4.9 eggs per nest. The demographic data from the Martinelli Ponds indicates a population skewed towards larger individuals, which is consistent with other locations elsewhere in California. This population data served to identify the Martinelli Ponds population as the donor site for a GOGA pond turtle headstart project. Nesting activity in 2017?2019 occurred from late May with activity peaking in mid-June and tapering off in mid-July. Visual surveys proved to be the most effective means of finding nesting females and nests; camera traps, VHF telemetry, and PIT antenna array costed time and money while not providing the desired information. Future inventory efforts should focus on resurveying lightly surveyed sites where we were not able to find northwestern pond turtles, periodic monitoring of abundance and demographic structure of main PORE population (Martinelli Ponds), and surveillance monitoring for invasive bullfrogs and turtles. Increasing public awareness of the status of northwestern pond turtles is another key action that will play a major role in their conservation.

Full text
Abstract:
Stratigraphic and lithogeochemical data were collected from selected drill core from the Nugget Pond gold deposit in the Betts Cove area, Newfoundland. The stratigraphy consists of a lower unit of basaltic rocks that are massive to pillowed (Mount Misery Formation). This is overlain by sedimentary rocks of the Scrape Point Formation that consist of lower unit of turbiditic siltstone and hematitic cherts/iron formations (the Nugget Pond member); the unit locally has a volcaniclastic rich-unit at its base and grades upwards into finer grained volcaniclastic/turbiditic rocks. This is capped by basaltic rocks of the Scrape Point Formation that contain pillowed and massive mafic flows that are distinctively plagioclase porphyritic to glomeroporphyritic. The mafic rocks of the Mount Misery Formation have island arc tholeiitic affinities, whereas Scrape Point Formation mafic rocks have normal mid-ocean ridge (N-MORB) to backarc basin basalt (BABB) affinities. One sample of the latter formation has a calc-alkalic affinity. All of these geochemical features are consistent with results and conclusions from previous workers in the area. Clastic sedimentary rocks and Fe-rich sedimentary rocks of the Scrape Point Formation have features consistent with derivation from local, juvenile sources (i.e., intra-basinal mafic rocks). The Scrape Point Formation sedimentary rocks with the highest Fe/Al ratios, inferred to have greatest amount of hydrothermally derived Fe, have positive Ce anomalies on Post-Archean Australian Shale (PAAS)-normalized trace element plots. These features are consistent with having formed via hydrothermal venting into an anoxic/ sub-oxic water column. Further work is needed to test whether these redox features are a localized feature (i.e., restricted basin) or a widespread feature of the late Cambrian-early Ordovician Iapetus Ocean, as well as to delineate the role that these Fe-rich sedimentary rocks have played in the localization of gold mineralization within the Nugget Pond deposit.

Full text
Abstract:
New evidence suggests that over four months after the closure of early childhood development (ECD) programmes on 18 March 2020, the ECD sector was likely to be operating at less than a quarter of its pre-lockdown levels. Of the 38 percent of respondents from the new NIDS-CRAM survey reporting that children aged 0-6 in their households had attended ECD programmes before the lockdown in March, only 12 percent indicated that children had returned to these programmes by mid-July, well after programmes were allowed to reopen. Using these findings, we estimate that just 13 percent of children aged 0-6 were attending ECD programmes by mid-July to mid-August compared to 47 percent in 2018. The last time that ECD attendance rates were as low as this was in the early 2000s. At this point it is not yet clear what proportion of these declines are only temporary, or whether there will be a lasting impact on ECD enrolment in the country. This dramatic contraction in the ECD sector relates to prohibitive costs to reopening ‘safely’ imposed by the regulatory environment, coupled with shocks to the demand side for ECD programmes (both in terms of reduced household incomes and parent fears of children contracting COVID-19). When viewed from a broader socio-economic lens, the threat of ECD programme closures across the nation will have impacts beyond ECD operators to the lives of millions of children, millions of households and millions of adults who rely on these ECD services. A swift intervention by government is necessary to save this important sector and limit the ripple effect of programme closures on multiple layers of society.

Full text
Abstract:
The National Park Service (NPS) Inventory and Monitoring (I&amp;M) Program conducts long-term ecological monitoring of high-priority indicator resources, deemed “vital signs.” This protocol documents the justification and procedure for monitoring breeding landbirds, a vital sign, in one of the 32 ecoregional I&amp;M networks, the National Capital Region Network (NCRN). “Landbird” refers to the many avian species that spend the majority of their lives in a terrestrial environment, including tree-dwelling birds, perching birds or songbirds, raptors, and ground-feeding birds. Landbird monitoring in the National Capital Region is conducted in both forest and grassland habitats throughout all 11 park units in the network. The mission of the National Park Service is to preserve “unimpaired the natural and cultural resources” of the over 85 million acres of park land throughout the U.S. This management objective underlies the impetus behind implementing long-term monitoring within each I&amp;M network. The NPS established five common programmatic goals for all 32 networks within the I&amp;M program as they plan, design, and implement integrated natural resource monitoring (Fancy et al. 2009). These goals are to: 1) determine the status and trends of selected indicators of park ecosystem conditions to make better-informed decisions and to work more effectively with other agencies and individuals for the benefit of park resources; 2) provide early warning of abnormal conditions of selected resources to help develop effective mitigation measures and reduce costs of management; 3) provide data to better understand the dynamic nature and condition of park ecosystems and to provide reference points for comparisons with other, altered environments; 4) provide data to meet certain legal and Congressional mandates related to natural resource protection and visitor enjoyment; and 5) provide a means of measuring progress towards performance goals. Landbird monitoring in the NCRN employs point count surveys to quantify the avian populations within each park. Point counts are a commonly used survey method that allows for both visual and auditory detections of individual birds and allows multiple surveys to be conducted in the same morning. For the NCRN Landbird Monitoring Protocol, point count surveys are conducted annually within forest and grassland habitats from mid-May through July. The NCRN Landbird Monitoring Protocol consists of a Narrative (this document) and Standard Operating Procedures (SOPs) outlining in-depth instructions for: (1) field season preparation, (2) field methods/sampling, (3) data analyses, and (4) database management.

Full text
Abstract:
Managers are challenged with the impact of problematic plants, including exotic, invasive, and pest plant species. Information on the cover, distribution, and location of these plants is essential for developing risk-based approaches to managing these species. Based on surveys conducted in 2006, 2011, 2015, and 2019, Heartland Network staff and contractors identified a cumulative total of 45 potentially problematic plant taxa in Lincoln Boyhood National Memorial. Of the 34 species found in 2019, we characterized 4 as very low frequency, 14 as low frequency, 9 as medium frequency, and 7 as high frequency. A single species exceeded a 10-acre threshold based on a mid-point estimate. Because of the number of problematic plant taxa, as well as the extent and cover of problematic plants in the park and the small park size, control efforts should focus on treating high priority species across the entire park. High priority species may include plant species capable of rapid spread, species at low population levels, and species which can effectively be controlled.

Full text
Abstract:
This research is aimed at finding a new type of notch that would produce propagation data similar to that produced by the PC DWTT. High-toughness materials and materials that had previously been studied were used assuming that if the new notch worked on these materials it would be satisfactory for lower toughness materials. Several notch modifications were tried and most were no better than the standard pressed notch used in the API specimen. A search for a new type of notch for the standard drop-weight-tear-test (DWTT) specimen has been completed. This new notch specimen is to replace the precracked DWTT specimen which has been shown to predict full-scale behavior but has received-little support from pipe manufacturers. The new notch is a chevron notch causing fracture initiation to occur at a machined point located at mid-wall thicknessand about 0.2 inch below the specimen edge (i.e., at the same depth as the pressed-in notch of the standard DWTT). No precracking or other severe prestraining, which may create strain aging problems, is required to produce the specimen. A good correlation was obtained between the chevron-notched DWTT and the Charpy V-notch specimens for conventionally rolled steels; this correlation effectively ties the chevron notched data to past fracture research data and to published correlations thatdescribe fracture in terms of Charpy upper-shelf energy. A procedure is included for preparing and conducting the Chevron notched DWTT.

Full text
Abstract:
The corpus luteum (CL) is a transient endocrine gland that has a vital role in the regulation of the estrous cycle, fertility and the maintenance of pregnancy. In the absence of appropriate support, such as occurs during maternal recognition of pregnancy, the CL will regress. Prostaglandin F2a (PGF) was first suggested as the physiological luteolysin in ruminants several decades ago. Yet, the cellular mechanisms by which PGF causes luteal regression remain poorly defined. In recent years it became evident that the process of luteal regression requires a close cooperation between steroidogenic, endothelial and immune cells, all resident cells of this gland. Changes in the population of these cells within the CL closely consort with the functional changes occurring during various stages of CL life span. The proposal aimed to gain a better understanding of the intra-ovarian regulation of luteolysis and focuses especially on the possible reasons causing the early CL (before day 5) to be refractory to the luteolytic actions of PGF. The specific aims of this proposal were to: determine if the refractoriness of the early CL to PGF is due to its inability to synthesize or respond to endothelin–1 (ET-1), determine the cellular localization of ET, PGF and tumor necrosis factor a (TNF a) receptors in early and mid luteal phases, determine the functional relationships among ET-1 and cytokines, and characterize the effects of PGF and ET-1 on prostaglandin production by luteal cell types. We found that in contrast to the mature CL, administration of PGF2a before day 5 of the bovine cycle failed to elevate ET-1, ETA receptors or to induce luteolysis. In fact, PGF₂ₐ prevented the upregulation of the ET-1 gene by ET-1 or TNFa in cultured luteal cells from day 4 CL. In addition, we reported that ECE-1 expression was elevated during the transitionof the CL from early to mid luteal phase and was accompanied by a significant rise in ET-1 peptide. This coincides with the time point at which the CL gains its responsiveness to PGF2a, suggesting that ability to synthesize ET-1 may be a prerequisite for luteolysis. We have shown that while ET-1 mRNA was exclusively localized to endothelial cells both in young and mature CL, ECE-1 was present in the endothelial cells and steroidogenic cells alike. We also found that the gene for TNF receptor I is only moderately affected by the cytokines tested, but that the gene for TNF receptor II is upregulated by ET-1 and PGF₂ₐ. However, these cytokines both increase expression of MCP-1, although TNFa is even more effective in this regard. In addition, we found that proteins involved in the transport and metabolism of PGF (PGT, PGDH, COX-2) change as the estrous cycle progresses, and could contribute to the refractoriness of young CL. The data obtained in this work illustrate ET-1 synthesis throughout the bovine cycle and provide a better understanding of the mechanisms regulating luteal regression and unravel reasons causing the CL to be refractory to PGF2a.
