This study involves the preparation of cement grout samples by varying proportions superplasticizer (SP) and water-cement (w/c) ratio (0.25-0.45) which were tested for computing flow value 1-day, 7-day, 28-day compressive strength. With 75 data points a neural network model was developed to predict strength based on w/c ratio, percentage, value, strengths 1-day 7-day as input variables. Due better performance Artificial Neural Networks (ANN) over other applied models, this predicts confident...

Background: Hypertension is one of the most common medical disorders associated with pregnancy. It second leading cause maternal mortality during pregnancy and affects in every ten cases. Maternal fetal complications hypertension can be highly destructive lead for example stroke, seizures, placental abruption, death, death etc. In current study, we tend to provide a comprehensive but short review literature relevant induced hypertension. Importantly, its prevalence distribution Pakistan...

To decrease the chances of misdiagnosis placenta accreta spectrum, a scoring method must be developed based on MRI features and clinical presentation patients. Objective: determine diagnostic accuracy PAS-system to diagnose considering per operative findings after cesarean section as gold standard Study design: It was cross sectional validation study Methods: The executed from Dec 2022 Jun 2023 at Department Radiology, Holy Family Hospital, Rawalpindi. Pregnant females 2nd or 3rd trimester,...

The depth of the induced stresses a rigid foundation known as significant depth, is related to width foundation. conventional bearing capacity equations can lead inaccuracies if top layer thickness less than In this study, series 3D numerical simulation analysis on various sizes are performed. Two different soil profiles with same underlain by, a) harder layers (Soil Profile A) and, b) weaker B), were used in study. settlement profile showed that occurred greater B. decreased significantly...

The sustainable development of materials is one the key targets in modern era engineering. These are developed by different waste products, following concept circular economy. This study focuses on investigating properties concrete using carbon black as a partial replacement natural fine aggregate at percentages. Experiments were designed according to British Standard (BS1881-Part-119) and American (ASTM C-78) including beams perform filler material develop concrete. In this study,...

Abstract We investigated the effects of continuous salt accumulation in root zone wheat. Leaf water potential and transpiration rate were measured plants grown an experimental pot system. Plants a controlled-environment glasshouse sand-filled pots, which groundwater table was maintained at desired depth. Saline recharged from base, providing constant content unsaturated zone. At 52 days after sowing, set depth 47 cm soil surface. Groundwater initial replaced with saline electrical...

Seismic numerical modeling technique provide most suitable way for the simulation of wave propagation through subsurface rocks and play an essential role in seismic interpretation, inversion evaluating designing a survey. In order to delineate more precisely, different approaches are proposed which solutions Biot's poroelastic equation given by using reflectivity, finite element difference algorithms. current study, forward method is quantify variation properties during its media exhibiting...

This research dealt with the impact of quality water source on mechanical properties construction materials. The materials include compressive, tensile, and flexural strength. Water samples were collected from different resources, these then synthetically investigated to identify compare their parameters. After a detailed chemical analysis three sources—wastewater, surface or canal water, ground water—construction concrete material prepared. developed same water–cement ratio, i.e., 0.60 for...

ABSTRACT In exploration geophysics, the efforts to extract subsurface information from wave characteristics exceedingly depend on construction of suitable rock physics model. Analysis different models reveals that strength and magnitude attenuation dispersion propagating wave‐induced fluid flow at multiple scales. current work, a comprehensive analysis velocity is carried out broad frequency range. Our methodology based Biot's poroelastic relations, by which variations in associated with due...

Sustainable engineering practices always provide an opportunity for engineers to produce long-term solutions. In the fields of construction and irrigation, soil bed formation symmetry is very important, especially in case its behavior with reference water runoff, whether natural or artificial. this study, different formations were tested help advanced hydrology apparatus under severe rainfall conditions. A major focus was observe retention volume discharge combinations slope level change....

Water remains one of the most important mediums for survival Living organisms. However, because human activities, it has lost its nature and becomes extremely polluted. Among various pollutants, synthetic dyes have huge contribution contamination natural water bodies their vast application in food, cosmetics, pharmaceutical, textile etc. The presence such hazardous contaminants causes cancer, kidney failure, dysfunction brain, infertility Consequently, removal is indispensable prior to...

Degradation due to hydro-salinity in the Indus basin semi-arid irrigated areas of Pakistanhas deteriorated vast productive agricultural land. The present approach was an effort throughvarious GIS and RS techniques using IRS-1B LISS II data along with field data/maps soil-waterquality indicators provide information about cause, extent magnitude problem adrainage project area. Strong relationship has been found between prone anddrainage network. Shortage irrigation water most limiting factor...

The paper deals with the application, calibration and validation of conceptual rainfall-runoff model for local catchment conditions. Watershed Model is applied to Kanshi River basin in north Pakistan.Model applied, calibrated verified using thirteen years data from 1971 1983. Conceptual mathematical models are a useful tool streamflow simulation. such has attracted attention hydrologists since unique optimal parameters difficult obtain. discussed through simple whose determined trial error technique.
