This document discusses using space technology to analyze erosion histories on Earth and Mars by reconstructing ancient river channels. It proposes mapping channels identified in seismic data from the North Atlantic and Mars to model uplift rates over time. This could provide insights into mantle dynamics beneath the North Atlantic and test theories of early plate tectonics and water cycling on Mars. The methodology involves reconstructing drainage networks from terrain data, modeling river profiles, and inverting models to determine uplift histories that fit observed profiles. Analyzing erosion patterns in this way could improve understanding of geological processes on multiple planets.
Proterozoic Milankovitch cycles and the history of the solar systemSérgio Sacani
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.

Artificial Recharge to Alluvial Aquifer, Northeastern Nuba Mountains, Sudan.IJRES Journal
Many engineering geology and structural geology aspects have been used in this study, to point out the suitability of the site for artificial recharge to alluvial aquifer, such as; rocks and soil types, seepage rate, structures and lineaments. The area is under lied by basement rocks with considerable thickness (10 to 15 m) of alluvial deposit. Overall soil type is sandy soil and its seepage rate is 34.56 Liter per hour. The most existing lineaments are trending toward NW direction while rocks foliation dipping toward WWN direction. The site is satisfied to be artificial recharge.
Remote Sensing & GIS based drainage morphometryAkshay Wakode
Remote sensing and Geographical Information Systems (GIS) techniques are increasingly being used for morphometric analysis of drainage basins throughout the world. GIS facilitates the manipulation and analysis of spatial information obtained using remote sensing. Integrating GIS and RS provides an efficient mechanism not only to upgrade and monitor morphometric parameters but also to permit spatial analysis of other associated thematic database. As compared to the conventional morphometric studies, remote sensing provides extant ground reality inputs for assessing changes in drainage patterns, density soil characteristics and land-use/land form changes in real life. Morphometry by and large, affects the hydrological processes rather indirectly through their dependency on several other factors such as soil, geology, vegetation cover and climate (Schmidt et al. 2000). The interrelationship between morphometric parameters varies from basin to basin under diverse topography and climatic condition. Understanding these relationship would enable the identification of the dominant parameters acting on a particular basin. An extensive and detailed analysis accounting for the various morphometric parameters under linear, areal and relief aspects of measurements was performed. The test site is located along the foothills of the Western Ghats, near the city of Pune and comprises of three large scale basins. The three rivers viz. Ghod, Bhima and Mula-Mutha, which are amongst the largest in the state, broadly consist of 23 sub-basins of Ghod, 22 of Bhima and 11 of Mula-Mutha.
The central area of the Mediterranean Sea is characterized by the bathymetric conformation of its seabed and especially for having been subjected, like other waters in the world, to transformations dependent on the change in sea level that caused the submergence at different stages and during the glacial and post-glacial periods, the emergence.

Hydrocarbon potential of the Borno Basin through Electrofacies and depositional environment analysis was carried out from well log and seismic reflection data to reassess the potential of the Basin thereby justifying the huge financial commitment of the Government. The reflection configuration pattern from the seismic reflection lines is characterized by variation from parallel, continuous and strong amplitude to sub parallel, chaotic discontinuous and low amplitude which indicate a variation from a low energy basinal setting of uniform rate of continental deposition to high energy environment of monolithologic deposits. Furthermore, the derivable log signatures shows a variation from serrated mud/sand to serrated blocky to serrated funnel and bell shapes with depth. This imply a stable massive mud/sand rich basinwide environment to an upward regressive sequence of bar deposit followed by a deltaic estuarine clastic sediment to gradual upward transgressive decrease in grain size to a fluvial point bar deposit. These environments identified from the research are known to be hydrocarbon province.
Neotectonics concerns the study of horizontal and vertical crustal movements that have occurred in the geologically recent past and which may be ongoing today. Though most crustal movements arise directly or indirectly from global plate motions (i.e., tectonic deformation), neotectonic studies make no presumption about the mechanisms driving deformation. Consequently, ‘movements’ is a vague catch-all term that encompasses a myriad of competing deformation processes, such as the gradual pervasive creep of tectonic plates, discrete (seismic) displacements on individual faults and folds, and distributed tilting and warping through isostatic readjustment or volcanic upheaval. The phrase ‘geologically recent past’ is also appropriately vague. Early attempts to define the discipline by arbitrary time windows (e.g., Late Cenozoic, Neogene, or Quaternary) have given ground to a more flexible notion that envisages neotectonism starting at different times in different regions. The onset of the neotectonic period, or the ‘current tectonic regime’, depends on when the contemporary stress field of a region was first imposed. For instance, the current tectonic regime began in the Middle Quaternary (∼700 000 years ago) in the Apennines of central Italy, and even more recently (<500 000 years ago) in California; in contrast, in eastern North America, the present-day stress regime has been in existence for at least the past 15 million years.
Typically then, neotectonic movements have been in operation in most regions for the past few million years or so. Over such prolonged intervals, neotectonic actions are revealed by the stratigraphic build-up of sediments in inland and marine basins, the burial or exhumation histories of rocks, and the geomorphological development of landscapes. Geological studies of palaeobotany and palaeoclimate, numerical models of landscape evolution, and techniques such as fission-track analysis and cosmogenic dating are among the disparate tools unravelling this long-term tectonic activity. Over periods of many tens of to several hundreds of thousands of years, the actions of individual tectonic structures (faults and folds) can be determined, unmasked by their deformation of geomorphic markers, such as marine and fluvial terraces, and tracked with reference to the Late Pleistocene glacial–eustatic time-frame. The apparently smooth deformation rates discerned over intermediate time-scales are revealed to be episodic and irregular when faults and folds are examined over Holocene (10 000 years) time-scales. Over millennial time-scales, secular variations in the activity of tectonic structures can be gleaned from a diverse set of palaeoseismological approaches, from interpreting the stratigraphy of beds that have been affected by faulting, to detecting disturbances in the growth record of trees or coral atolls.
Delineation of Hydrocarbon Bearing Reservoirs from Surface Seismic and Well L...IOSR Journals
Hydrocarbon reservoir has been delineated and their boundaries mapped using direct indicators from 3-D seismic and well log data from an oil field in Nembe creek, Niger Delta region. Well log signatures were employed to identify hydrocarbon bearing sands. Well to seismic correlation revealed that these reservoirs tied with direct hydrocarbon indicators on the seismic section. The results of the interpreted well logs revealed that the hydrocarbon interval in the area occurs between 6450ft to 6533ft for well A, 6449ft to 6537ft for well B and 6629ft to 6704ft for well C; which were delineated using the resistivity, water saturation and gamma ray logs. Cross plot analysis was carried out to validate the sensitivity of the rock attributes to reservoir saturation condition. Analysis of the extracted seismic attribute slices revealed HD5000 as hydrocarbon bearing reservoir.
Remote Sensing Technique as Exploration Tool for Ground water in Parts of the...theijes
The study area lies within latitudes 8°00' – 9°00'N and longitudes 11°30' – 12°30'E. Analysis of remote sensing imageries of part of the Upper Benue Trough of Nigeria was carried out on a scale of 1:100,000. The aim of this study includes the structural interpretation of the remote sensing data and the identification of the lineament and drainage patterns associated with the area to infer the influence of such structures on the economic potential of the basin. Results of the structural analysis revealed numerous lineaments. Trend analysis of the lineaments plotted on a rose diagram using the strikes and lengths of the entire lineaments revealed structural trends predominating in the NE-SW direction. The absence of visible lineaments in parts of the area may not indicate absence of geological structures. Some of these lineaments were found on some drainages showing that the drainages in those areas are structurally and tectonically controlled. The areas where the lineaments cross each other are indicative of groundwater availability and there correspond to regions of mean topographic height of about 900m

Modern water at low latitudes on Mars: Potential evidence from dune surfacesSérgio Sacani
Landforms on the Martian surface are critical to understanding the nature of surface processes in the recent
past. However, modern hydroclimatic conditions on Mars remain enigmatic, as explanations for the formation
of observed landforms are ambiguous. We report crusts, cracks, aggregates, and bright polygonal ridges on the
surfaces of hydrated salt-rich dunes of southern Utopia Planitia (~25°N) from in situ exploration by the Zhurong
rover. These surface features were inferred to form after 1.4 to 0.4 million years ago. Wind and CO2 frost processes can be ruled out as potential mechanisms. Instead, involvement of saline water from thawed frost/snow is
the most likely cause. This discovery sheds light on more humid conditions of the modern Martian climate and
provides critical clues to future exploration missions searching for signs of extant life, particularly at low latitudes with comparatively warmer, more amenable surface temperatures.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
