Continental Mapping Projects - FEMA Butler Co. MO
FEMA identified changes to the Black River in Missouri that required new flood modeling from Highway 60 north of Poplar Bluff to the Arkansas border. Continental Mapping performed a hydrographic survey of the 46 mile river section, surveying cross sections, bridges, and drainage structures. Using GPS and an echosounder, they surveyed river edges, extended levee sections, the river flowline, 11 road bridges, 3 railroad bridges, and 13 drainage structures to provide data for updated floodplain modeling within 5cm accuracy.
Marine data model jeff fennell
The Marine Data Model was first conceived in 2001 by ESRI, Duke University, NOAA, and Oregon State University to create a data model for coastal and ocean environments. It is used to model phenomena like marine mammal migrations, oil spills, and algae blooms. The model represents features like tracks, time series data, survey transects, and bathymetry using points, lines, polygons, and volumes.
2016 conservation track: automated river classification using gis delineated ...
The document describes an automated GIS tool called RESonate that is used to classify river systems into functional process zones (FPZs) based on hydrogeomorphic characteristics. The tool extracts over a dozen variables like elevation, slope, and width from geospatial datasets. It then uses these variables to generate sample points and calculate additional metrics. Statistical analysis is applied to cluster sample segments into distinct FPZ classes. The tool was tested on the Carson River where it identified 5 FPZ classes. The goal of the tool is to provide a consistent classification method that can enhance compatibility between river analyses and improve communication among scientists.

This study uses unsupervised seismic facies classification techniques on a 3D seismic volume from the Lower Strawn Formation in the Bend Arch-Fort Worth Basin of Texas to differentiate sand bodies and delineate architectural elements within the target formation. The authors extract attributes from the seismic data after conditioning and perform an impedance inversion. They classify the data using k-means clustering, self-organizing maps, and principal component analysis and find that while k-means highlights potential channel and bar features, self-organizing maps and principal component analysis better discriminate more subtle facies changes in specific areas. The results provide insight into the depositional history and 3D seismic expression of the turbidite/submarine fan complex within the Lower Straw

Improved Projections of 21st Century Trans-Arctic Shipping
This document summarizes research projecting increased opportunities for trans-Arctic shipping through the 21st century due to continued sea ice melt. The researchers used bias-corrected global climate models to simulate shipping routes for open water and polar class 6 vessels from East Asia to Europe and the USA. Their results showed the potential for trans-Arctic shipping doubles by mid-century, coinciding with the opening of the trans-polar sea route. They also found shipping seasons become more reliable and longer through the century, though with inter-annual variability remaining. Figures 1 and 2 in the document illustrate projected shipping routes and increasing season length over time.
Application of integrated geophysical technique for the mapping
The document summarizes the application of integrated geophysical techniques to map old foundation pilings at a site in Penang, Malaysia. Magnetic gradiometry and ground penetrating radar (GPR) were used successfully to detect the buried concrete pilings, while gravity, multi-channel analysis of surface waves and time domain electromagnetics could not be applied due to site conditions and limitations of the methods. The location of detected pilings from the geophysical surveys was later confirmed through field inspections. The mapping of the old foundation pilings will help accelerate development of a new project at the site.

The document summarizes a study that used LIDAR data from 2005 and 2009 to analyze changes in elevation of gravel bars and the migration of channels in a section of the North Fork of the Nooksack River in Washington. Bare earth layers were generated from the LIDAR data and analyzed in ArcGIS to detect changes. Results showed gravel bars gained up to 4 meters and lost up to 3 meters in elevation over the 4 year period, indicating significant river migration. While LIDAR only measures surface elevations, the analysis demonstrated it can effectively monitor short-term stream changes and the method has various applications for research and conservation efforts.

This document summarizes research applying time domain electromagnetic (TDEM) and magnetic gradiometer techniques to locate water leakage from buried iron pipes in Sungai Klah, Perak, Malaysia. The study aims to 1) locate leakage sites along distribution pipes and 2) demonstrate the potential of integrated geophysical methods to solve similar problems. Magnetic gradiometer and TDEM surveys were conducted over pipe locations. Magnetic gradiometer was able to map the iron pipes and identify leakage sites, while TDEM detected a relatively deep conductive anomaly possibly unrelated to leakage at the site. The research concludes these geophysical methods can successfully locate leakage positions and determine leakage sites to address water waste and loss of resources.

This document provides an update on the PALEOMAP Project. It thanks sponsors who have supported the PaleoAtlas. It highlights accomplishments in 2013, including a new global plate model, finalizing over 100 paleogeographic time slices in the PaleoAtlas, and beginning work on an Earth System Archive to define over 50 paleoclimate and paleoenvironmental variables. Plans for 2014 include further developing the Earth System Archive with additional paleoclimate simulations, adding new data layers to the PaleoAtlas, and continuing work on a book documenting Earth's history.Introduction to some basics
This document presents a new approach to determining hydraulic flow units in reservoirs using mathematical modeling. It begins with definitions of reservoir characterization, rock typing, and hydraulic flow units. It then reviews previous literature on defining flow units both qualitatively and quantitatively. The proposed approach uses a modified version of the Amaefule method for determining flow zone indicators and reservoir quality indices. The scope of work involves mathematically formulating the new model based on Amaefule's assumptions but with different boundary conditions, performing core analysis experiments to validate the model, and upscaling the results using well log data.

Abstract
Construction is one of the area in which computer application software are highly required to perform different task at various stages of project construction. Computers have been used to enhance the effectiveness of construction management. Efficient utilization of computer application software is a key to enhancing the proper management of construction activities which will contribute to the successful implementation of construction project. Careful selection of computer application software is required by the construction companies for proper management of their resources. The difficulty about computerization especially with regard to the use of computer application software in resource management require the knowledge and expertise of those working in construction companies, and who are directly involved in the management of construction resources. The study was carried out to determine the obstacles confronting the proper utilization of computer application software in resource management. The result of the questionnaire survey used in this research work clearly indicated those constraints, which include, non-understanding about software potentials, lack of qualified personnel to use the software, unaware of most of the resource management software available in the market, communication gap between the vendors and users which contribute to non-understanding of the full scope of the software, greater-know-how required from staff, among numerous others. A total of 22 construction companies were selected for the study. An open ended questionnaire which consist of 22 questions with regard to the constraints affecting the proper utilization of computer application software in resource management was designed, validated, and distributed among Engineers, Project Managers, as well as executives who are directly involved in the activities of the construction site.

It provides dates for acquiring properties, completing site preparation, foundations, construction stages, and occupancy for each project, with the earliest occupancy date being August 2008 and the latest being October 2009.
10 lecture project scheduling 2
The document discusses project scheduling and network diagrams. It defines key terms like work breakdown structure and activities. It explains that a network schedule graphically shows the logical sequence of project events. A network diagram is developed by defining activities and determining which must precede or follow others. The diagram shows the efficient order that work will follow to complete the project. Milestones mark important points but do not consume time or resources like activities.
Rock Formation Q & A
The document provides information about rock formation and classification. It defines igneous, sedimentary and metamorphic rocks. Igneous rocks form from cooling magma, either below the surface (intrusive) or above (extrusive). Sedimentary rocks form through compaction and cementation of sediments. Metamorphic rocks form from changes to existing rocks through heat, pressure and fluids. Rocks are classified based on texture, composition and formation processes. The rock cycle illustrates how rocks continuously change between the three main types through various natural processes.
Materials and methods of construction
This document provides an overview of materials and methods of construction for a civil engineering course. It discusses 1) why buildings are needed for shelter and human activities, 2) stakeholders in building design like owners, architects, and contractors, 3) constraints on building system selection like codes, budgets, and site conditions, 4) how to choose building systems based on performance, cost, and sustainability, and 5) ensuring buildings perform as intended both during and after construction. It also provides a brief overview of civil engineering materials commonly used in Newfoundland and Labrador.
QCL 14 v3 Pareto diagram, Banasthali University, Sugandha Kapoor
The document discusses Pareto diagrams and the causes of potholes. It defines a Pareto diagram as a bar graph that arranges causes by frequency, with the most frequent on the left. For potholes, the top three causes accounting for 80% are:
1) Snow and rain water seeping into cracks and eroding the road base.
2) Cracking of asphalt surfaces allowing water infiltration and stripping of asphalt layers.
3) Poor or temporary repairs of potholes that fail to provide a permanent fix.
Study on solar irrigation system in bangladesh
This document summarizes a study on solar irrigation systems in Bangladesh. It discusses how agriculture is important to Bangladesh's economy but irrigation is challenging due to water scarcity. Currently, irrigation is powered by conventional electricity or diesel generators. The study proposes using solar power as a more cost-effective solution for irrigation. It describes different types of solar irrigation systems and notes that solar is most competitive for low-pressure irrigation needs. Present solar power generation in Bangladesh is around 15-20 MW but there is potential to increase irrigation powered by solar.
Fundamentals of engineering geology
This document provides an overview of engineering geology and rock mechanics. It discusses fundamentals such as lithology, rock structures, weathering, and rock mass classification systems. It also presents a case study on the 1928 failure of the St. Francis Dam in California, which was caused by unsuitable geological conditions including weakness along the San Francisquitto fault that were not properly considered in the dam's design and construction. The case study demonstrates the importance of engineering geological considerations for civil works.
5.plastering
Plastering involves covering rough or uneven surfaces with a plastic material to create a smooth finish. It provides protection from weathering, conceals imperfections, and allows for painting or other decorative finishes. There are different types of plaster depending on the binding material used, including cement, mud, lime, and lime cement. Cement plastering typically involves applying multiple thin coats over a period of days to allow drying in between. Proper curing and avoiding excess thickness helps prevent common defects like cracking during the plastering process.

Mineralogy of a_mudstone_at_yellowknife_bay_gale_crater_mars
The document summarizes the mineralogical analysis of two mudstone samples, John Klein and Cumberland, collected from Yellowknife Bay on Mars by the Curiosity rover. X-ray diffraction analysis found that the samples contain detrital basaltic minerals, calcium sulfates, iron oxides/hydroxides, iron sulfides, amorphous material, and trioctahedral smectites. The smectite in John Klein has a basal spacing of ~10 Å indicating little water interlayer hydration, while Cumberland smectite has a spacing of ~13.2 Å, suggesting partial chloritization or interlayer ions that facilitate water retention. The mudstone minerals are similar to nearby eolian deposits but
Xray diffraction results_from_msl_mineralogy_of_rocknest_at_gale_crater
The x-ray diffraction analysis of soil samples from Rocknest at Gale Crater on Mars revealed:
1) Crystalline components including plagioclase, olivine, augite, pigeonite, and minor amounts of other phases.
2) 27±14% of the soil was amorphous material, likely containing multiple iron-bearing and volatile phases including possibly hisingerite.
3) The crystalline components are similar to martian basalts and meteorites, while the amorphous component is similar to soils on Earth like those on Mauna Kea, Hawaii.
Karakterisasi Letusan Merapi menggunakan Data SAR (Synthetic Aperture Radar)
The document summarizes research using Synthetic Aperture Radar (SAR) data and other remote sensing data to characterize eruptions of Mount Merapi volcano in Indonesia over the last decade. SAR data from 1996-2006 was used to detect and analyze pyroclastic flow deposits from each eruption. ALOS/PALSAR SAR data observed the large 2010 eruption, detecting pyroclastic deposits 7 times larger than 2006. Interferometric SAR, thermal infrared data, and field measurements were used to analyze ground deformation, lava dome growth, and surface temperatures as precursors to the 2010 eruption. Inflation was detected in 2008 and 2010 via SAR interferometry.

Mapping Hydrothermal Mineral Deposits Using PCA and BR Methods in Baft 1:1000...INFOGAIN PUBLICATION
Evaluating the conventional methods for mapping hydrothermal altered deposits by using landsat-8 OLI images in the Baft one to one hundred thousand geological Sheet is the prime target of our study. We used the color composite, band ratio, principal component analysis. The color composite and band ratio methods showed very clearly the hydrothermal altered deposits of clay minerals, iron oxides and ferric oxides around the fumaroles. The principal component analysis also enabled us to represent undoubtedly the altered hydroxyl and iron oxide mineral deposits of this region concentrating around the fumaroles. Finally, the target detection method for reference spectral analysis by using EnvI 4.8 detected the representative hydrothermal altered minerals around study area. Therefore, all the methods showed high efficiency for mapping hydrothermal altered mineral deposits. Lumleyetal-intro4D-2015
This document introduces a special section on advances in time-lapse geophysics. It summarizes that time-lapse geophysics is an important method for monitoring complex subsurface processes over time, with applications in resource management, geohazards, environmental issues, and more. Recent innovations allow for improved 4D signal detection, more frequent/continuous monitoring, and extraction of more detailed subsurface information in near real-time. The special section aims to present state-of-the-art technical articles on time-lapse geophysics across applications, theories, data acquisition, and analysis to convey new developments and stimulate further research.
The petrochemistry of_jake_m_a_martian_mugearite
The rock "Jake_M" was the first rock analyzed by Curiosity on Mars. It has a distinct chemical composition compared to other known Martian rocks. Jake_M has a basaltic composition but is alkaline, with over 15% normative nepheline content. Its chemical makeup is similar to terrestrial mugearites, fractionated alkaline rocks found at ocean islands and rifts. This suggests Jake_M formed through extensive fractional crystallization of an alkaline magma at elevated pressure, possibly with water. The discovery of an alkaline rock expands the diversity of known Martian igneous compositions.
Ancient aqueous environments_at_endeavour_crater_mars
The document summarizes findings from the Mars Exploration Rover Opportunity regarding ancient aqueous environments at Endeavour Crater on Mars. CRISM orbital data identified a location with a spectral signature of Fe3+-rich smectite clay minerals. Opportunity investigated this area in detail called the Matijevic formation. It found fine-grained layered rocks containing spherical concretions and was cut by calcium sulfate veins. Composition data suggests the rocks formed from aqueous leaching that altered the rocks to aluminum-rich smectites. This provides evidence for water-rock interactions before and after the impact, under slightly acidic to neutral pH environments that could have been more favorable for prebiotic chemistry.

We analyse Hubble Space Telescope observations of six globular clusters in the Large Magel- lanic Cloud (LMC) from programme GO-14164 in Cycle 23. These are the deepest available observations of the LMC globular cluster population; their uniformity facilitates a precise comparison with globular clusters in the Milky Way. Measuring the magnitude of the main- sequence turn-off point relative to template Galactic globular clusters allows the relative ages of the clusters to be determined with a mean precision of 8.4 per cent, and down to 6 per cent for individual objects. We find that the mean age of our LMC cluster ensemble is identical to the mean age of the oldest metal-poor clusters in the Milky Way halo to 0.2 ± 0.4 Gyr. This provides the most sensitive test to date of the synchronicity of the earliest epoch of globular cluster formation in two independent galaxies. Horizontal branch magnitudes and subdwarf fitting to the main sequence allow us to determine distance estimates for each cluster and examine their geometric distribution in the LMC. Using two different methods, we find an average distance to the LMC of 18.52 ± 0.05.

History was made when NASA sent the Mars Science Laboratory, better known as the Curi-osity rover, to Mars. Arriving August 2012 at
Gale Crater, Curiosity began exploring the Martian
surface, analyzing soil and rock samples, and send-
ing images and data back to Earth. One aspect of
exploration is to gain a better understanding of the
geological makeup of Mars. While Curiosity has giv-
en scientists insight into the nature and composition
of Mars, physical Martian samples must be retrieved
and investigated to ascertain an accurate geological
history of the red planet. In 2020, another rover, yet
to be named, will be sent to Mars to continue explor-
ing the planet (NASA 2017a).
In what seems like science fiction, core samples
on Mars will be collected, packaged, and returned to
an established launching device that will transport
the samples to Earth (NASA 2017b). This process op-
erates like an interplanetary t-shirt cannon, loading
rock samples into a sample launcher that will fire the
Martian rocks back to Earth, and represents a com-
plex network of devices and satellites that make up
the Mars Sample Return (MSR) Program.
While still in its infancy, the MSR epitomizes the
need to attract young students to science. These stu-
dents will be the future investigators, and developing
consequential studies that they can partake in at the
onset of their science education is essential for ad-
vancing interest in projects such as the MSR. The ac-
tivity described in this article was developed with the
goal of increasing middle school students’ interest in
science using a multidisciplinary geology and chem-
istry project that revolves around the MSR program.

tation is shared regarding the forthcoming research

The Curiosity rover analyzed samples of Martian fines from the Rocknest site using its Sample Analysis at Mars (SAM) instrument suite. SAM detected water, sulfur dioxide, carbon dioxide, and oxygen as the major gases released when heating the fines. The water content and release temperature suggest the water is bound in amorphous materials. Much of the carbon dioxide was likely released from the decomposition of fine-grained iron or magnesium carbonates. Elevated levels of deuterium indicate recent interaction with the atmosphere. Several simple organic compounds were detected but are not definitively of Martian origin.

Diffuse reflectance spectroscopy to estimate soil attributes of Brazilian wet...Agriculture Journal IJOEAR
Abstract— The study of soils and characterization of its attributes are continually evolving, however, for the condition of wetlands, such information is still scarce and poorly distributed. Thus, the objective of this work was to characterize spectrally the soils of a wetland area. On the study area were collected georeferenced soil samples and sent for chemical and physical analysis routine and then subjected to spectral evaluation. Were identified seven soil classes with hydromorphic characteristics in their spectral curves? The information contained in these curves then led the development of equations for soil attributes. Sand was the physical attribute of a better correlation with laboratory data and Cationic Exchange Capacity (CEC), the chemical attributes that showed better results.The pristine nature of SMSS 1605−1443 revealed by ESPRESSO
SMSS J160540.18−144323.1 is the carbon-enhanced metal-poor (CEMP) star with the lowest iron abundance ever measured, [Fe/H] =
−6.2, which was first reported with the SkyMapper telescope. The carbon abundance is A(C) ≈ 6.1 in the low-C band, as the majority of the stars
in this metallicity range. Yet, constraining the isotopic ratio of key species, such as carbon, sheds light on the properties and origin of these elusive
stars.
Aims. We performed high-resolution observations of SMSS 1605−1443 with the ESPRESSO spectrograph to look for variations in the radial
velocity (vrad) with time. These data have been combined with older MIKE and UVES archival observations to enlarge the temporal baseline. The
12C/
13C isotopic ratio is also studied to explore the possibility of mass transfer from a binary companion.
Methods. A cross-correlation function against a natural template was applied to detect vrad variability and a spectral synthesis technique was used
to derive 12C/
13C in the stellar atmosphere.
Results. We confirm previous indications of binarity in SMSS 1605−1443 and measured a lower limit 12C/
13C > 60 at more than a 3σ confidence
level, proving that this system is chemically unmixed and that no mass transfer from the unseen companion has happened so far. Thus, we confirm
the CEMP-no nature of SMSS 1605−1443 and show that the pristine chemical composition of the cloud from which it formed is currently imprinted
in its stellar atmosphere free of contamination.
Proterozoic Milankovitch cycles and the history of the solar system
The geologic record of Milankovitch climate cycles provides a rich
conceptual and temporal framework for evaluating Earth system
evolution, bestowing a sharp lens through which to view our
planet’s history. However, the utility of these cycles for constraining
the early Earth system is hindered by seemingly insurmountable
uncertainties in our knowledge of solar system behavior
(including Earth–Moon history), and poor temporal control for validation
of cycle periods (e.g., from radioisotopic dates). Here we
address these problems using a Bayesian inversion approach to
quantitatively link astronomical theory with geologic observation,
allowing a reconstruction of Proterozoic astronomical cycles, fundamental
frequencies of the solar system, the precession constant,
and the underlying geologic timescale, directly from stratigraphic
data. Application of the approach to 1.4-billion-year-old rhythmites
indicates a precession constant of 85.79 ± 2.72 arcsec/year (2σ),
an Earth–Moon distance of 340,900 ± 2,600 km (2σ), and length of
day of 18.68 ± 0.25 hours (2σ), with dominant climatic precession
cycles of ∼14 ky and eccentricity cycles of ∼131 ky. The results
confirm reduced tidal dissipation in the Proterozoic. A complementary
analysis of Eocene rhythmites (∼55 Ma) illustrates how the
approach offers a means to map out ancient solar system behavior
and Earth–Moon history using the geologic archive. The method
also provides robust quantitative uncertainties on the eccentricity
and climatic precession periods, and derived astronomical timescales.
As a consequence, the temporal resolution of ancient Earth
system processes is enhanced, and our knowledge of early solar
system dynamics is greatly improved.
A statistical analysis_of_the_accuracy_of_the_digitized_magnitudes_of_photome...
We present a statistical analysis of the accuracy of the digitized magnitudes of photometric plates on
the time scale of decades. In our examination of archival Johnson B photometry from the Harvard
DASCH archive, we nd a median RMS scatter of lightcurves of order 0.15mag over the range B
9 17 for all calibrations. Slight underlying systematics (trends or
ux discontinuities) are on a level
of . 0:2mag per century (1889{1990) for the majority of constant stars. These historic data can
be unambiguously used for processes that happen on scales of magnitudes, and need to be carefully
examined in cases approaching the noise
oor. The characterization of these limits in photometric
stability may guide future studies in their use of plate archives. We explain these limitations for the
example case of KIC8462852, which has been claimed to dim by 0:16mag per century, and show that
this trend cannot be considered as signi cant.

The document discusses five different rock typing methods commonly used for carbonate reservoirs: Hydraulic Flow Unit (HFU), Global Hydraulic Element (GHE), Pore Geometry Structure (PGS), Jennings-Lucia, and Winland R35. It analyzes these methods by applying them to core data from the Minahaki Formation and comparing the resulting rock types using Leverett J-Functions. The HFU, GHE, and PGS methods group rock types based on integration of geological and petrophysical parameters, while the others focus more on petrophysical properties. The analysis finds that the most consistent method for this reservoir is one that integrates both geological description and engineering hydraulic features.
Chaki2015 (3)
This document presents a novel preprocessing scheme to improve prediction of sand fraction from seismic attributes using neural networks. The scheme consists of three steps: 1) preprocessing the high-resolution well log sand fraction data using techniques like Fourier transform, wavelet decomposition, and empirical mode decomposition to better match the low-resolution seismic attributes, 2) training an artificial neural network on the preprocessed data, and 3) postprocessing the network predictions with 3D spatial filtering. The proposed preprocessing scheme is found to produce significantly better predictions of sand fraction compared to using the original well log data, helping with reservoir characterization from seismic data.
Soil diversity and_hydration_as_observed_by_chemcam_at_gale_crater_mars
The ChemCam instrument on the Curiosity rover identified two main soil types on Mars - a fine-grained mafic soil and a coarse-grained felsic soil locally derived. The mafic soil is similar to widespread martian soils and dust, and possesses a ubiquitous hydrogen signature from hydrated amorphous phases. This hydration may account for a significant fraction of hydrogen detected globally on Mars. ChemCam analyses did not reveal water vapor exchange between the soil and atmosphere. The observations provide constraints on the nature and hydration of amorphous phases in the soil.
Phosphine gas in the cloud decks of Venus
The document reports the discovery of phosphine (PH3) gas in Venus's atmosphere based on millimeter-wave spectral detections from the JCMT and ALMA telescopes. Detections of absorption at the predicted wavelength of the PH3 1-0 rotational transition were observed to be consistent with Venus' velocity. The inferred PH3 abundance is approximately 20 parts per billion. However, the presence of PH3 in Venus' atmosphere is currently unexplained as there are no known abiotic production mechanisms for PH3 under Venus' atmospheric conditions. The PH3 could potentially originate from unknown photochemistry or geochemistry, or from the presence of life by analogy to biological PH3 production on Earth. Further observations are needed to confirm the detection

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

- 12. 12 Comparative Petrographic Analysis of Volcanic Rocks in 5 Different Areas Using R 3/10/2016 Conclusion Based on the results of the PCA and CA showed different results, we think the Dendogram is better, because the dendogram (figure 5) shows the 3 classification based on mineral composition that show a significant difference, namely cluster 1 Quaternary volcanic rock, cluster 2 sedimentary rocks, and cluster 3 tertiary volcanic rocks. we perceive that multivariable statistics can support visual petrographic analysis by reading the data structure, selecting stronger variables and extracting clusters.
