In the present work, radon gas concentrations in different surface soil samples in Baghdad governorate were measured using RAD-7 detector. The results have been shown that, the Radon gas concentrations ranged between (41.67±1.78Bq/m3), to (185.67±4.22Bq/m3), a map showing the distribution of the concentration of radon in selected areas was defined to identify areas with high pollution level. The reason for the high concentration of radon is that these surface soil samples are taken from agricultural areas. It is also known that fertilizers contain uranium levels as well as areas bombed in wars in the country. It is worth noting that all radon concentrations in Baghdad governorate are below the recommended minimum of 200-300Bq/m3) (Inte

This was followed by CaP1P2 treatment, with 43.7% weight loss and 4.48 kg·cm⁻² firmness after 24 days of cold storage, and 45.87% weight loss w

This research demonstrates an efficient method for the synthesis and storage of molecularly imprinted polymers (MIP) using bulk polymerization of Pregabalin (PGB), which is carried out at room temperature. This method has the advantages of high sensitivity, low cost, increased stability, and longer lifetime of the polymers. The research used specific ratios between template, monomer, and cross-linking agents to ensure suitable adsorption capacity. Benzoyl peroxide (BPO) was used as an initiator for the functional monomer styrene and ethylene glycol dimethacrylate (EGDMA) cross-linking to create the MIP of Pregabalin (PGB-MIP). The molecularly imprinted polymer was studied using ultraviolet-visible spectroscopy (UV-VIS) a

This study experimentally investigated Free-Fall Gravity Drainage (FFGD) under combination-drive conditions in a two-dimensional Hele-Shaw model representing a water-drive reservoir. An initially high gravity potential from the oil column enabled early oil drainage before aquifer support became dominant. Three water-drive strengths were tested, demonstrating that a stronger aquifer (1.15 psig) accelerated oil recovery to approximately 75% of the original oil in place (OOIP) within 60 minutes, resulting in a final recovery of 79.5%. However, this was accompanied by rapid water breakthrough after 2.5 minutes and high-water cuts exceeding 90%. In contrast, a weaker aquifer (0.725 psig) stabilized the oil–water contact

In this study presents a numerical investigation of natural convection heat transfer in an annular enclosure partially filled with metal foam. The inner cylinder is maintained at a constant temperature, while the outer cylinder is subjected to a uniform heat flux; both vertical sidewalls are thermally insulated. The fluid flow is modeled using the Navier–Stokes equations under the Boussinesq approximation, and the porous medium is described by the Brinkman–Forchheimer Darcy model, assuming local thermal equilibrium. Simulations are conducted using ANSYS FLUENT to examine the effects of pore density (10 PPI and 40 PPI), inclination angle (0°, 30°, 60°, 90°) and Rayleigh number (10⁴ ≤ Ra ≤ 10⁶) on thermal p

This study evaluates the performance of Self-Compacting Engineered Cementitious Composites (SCC-ECC) under standard 28-day water curing, aiming to develop a mixture with optimal flowability, high mechanical strength, and enhanced durability. Twenty-seven SCC-ECC mortar mixtures (without coarse aggregate) were prepared and tested according to EFNARC (2002) guidelines for self-compacting mortars. Fresh results (slump flow 240–260 mm, V-funnel 6–12 s, L-box >0.80) confirmed adequate flowability. In addition, direct tensile tests on dog-bone specimens demonstrated strain-hardening with multiple fine cracks and strain capacity exceeding 2%, verifying the ECC behavior. The mixtures were prepared with varying fly ash con

In this paper two main stages for image classification has been presented. Training stage consists of collecting images of interest, and apply BOVW on these images (features extraction and description using SIFT, and vocabulary generation), while testing stage classifies a new unlabeled image using nearest neighbor classification method for features descriptor. Supervised bag of visual words gives good result that are present clearly in the experimental part where unlabeled images are classified although small number of images are used in the training process.

Background: Dental caries is generally given the highest priority in national oral health services for adult populations.

The relationship between cinema and architecture has witnessed an increasing presence in contemporary studies, as both converge at a common point: shaping human experience within a specific temporal and spatial space. Cinema uses the principles of rhythm, sound, and memory to shape visual and auditory narratives, while architecture seeks to embody these principles in tangible spaces that organize human movement and influence sensory and emotional perception. This relationship demonstrates that cinematic expression tools can enrich architectural experience. However, the challenge lies in the limited theoretical frameworks that explain how to translate these principles into design strategies, particularly in cultural archi

The process of drilling wells has become more complex today due to greater depths and advanced drilling techniques. Therefore, obtaining ideal specifications for drilling fluids has become of great importance to overcome drilling problems and reduce costs. Therefore, studies have begun to investigate the effect of nanomaterials on drilling fluids. This study is an investigation into the effect of nano-iron oxide on drilling fluid specifications.

This study examined different inflammatory markers within gingival crevicular fluid, including matrix metalloproteinases 8 (MMP8), tissue inhibitors of metalloproteinases 1 (TIMP1), receptor activator of nuclear factor κB (RANK), its ligand (RANKL), and osteoprotegerin (OPG), to be used in comparing symptomatic apical periodontitis (SAP) and asymptomatic apical periodontitis (AAP) versus healthy teeth. Subjects with SAP, AAP, and a control group were recruited and GCF samples were collected by Periopaper strips. Clinical and radiographical measures were used f

One way to synthesis texture in a fast and easy way is image quilting proposed by Efros and Freeman in
2001. This research brings the adaptive search power of genetic algorithm and combines it with the
concept of image quilting to propose new texture synthesis algorithm. The proposed GA is ran on many
different images from standard texture sets. Visual comparison of our proposed GA with image quilting
algorithm is considered. The texture results generated by the proposed GA are roughly comparable in
quality to those generated from Efros and Freeman algorithm.

Storage of rainwater within the root depth zone is one of the modern ways to increase plant production. Subsurface water retention technology was applied to assess improving values of crop yield and crop water use efficiency, applying a membrane made of low-density polyethylene trough installed below the crop root zone. The goal of this paper is to assess that the retention of rainwater above the membrane can improve the crop yield and crop water use efficiency values for winter wheat. The experiment was conducted in open field, within Joeybeh Township, located in east of the Ramadi City, in Anbar Province, in winter growing season 2018-2019. Two plots T1 (with membrane trough) and T2 (without membrane) were used for the

Because of the quick growth of electrical instruments used in noxious gas detection, the importance of gas sensors has increased. X-ray diffraction (XRD) can be used to examine the crystal phase structure of sensing materials, which affects the properties of gas sensing. This contributes to the study of the effect of electrochemical synthesis of titanium dioxide (TiO₂) materials with various crystal phase shapes, such as rutile TiO₂ (R-TiO₂NTs) and anatase TiO₂ (A-TiO₂NTs). In this work, we have studied the effect of voltage on preparing TiO₂ nanotube arrays via the anodization technique for gas sensor applications. The results acquired from XRD, energy dispersion spectro

The present study deals with the experimental investigation of buried concrete pipes. Concrete pipes are buried in loose and dense conditions of gravelly sand soil and subjected to different surface loadings to study the effects of the backfill compaction on the pipe. The experimental investigation was accomplished using full-scale precast unreinforced concrete pipes with 300 mm internal diameter tested in a laboratory soil box test facility set up for this study. Two loading platforms are used namely, uniform loading platform and patch loading platform. The wheel load was simulated through patch loading platform which have dimensions of 254 mm *508 mm, which is used by AASHTO to model the wheel load of a HS20 truck. The pipe-soil system

The effects of temperature on an exotic aquatic snail Pomacea canaliculata  (Lamarck, 1819) collected from the Shatt Al-Arab intertidal zone were investigated. A series of laboratory experiments were conducted during the summer period of 2017. Individuals of new born snails hatched in the laboratory from adult snails were collected from Shatt Al-Arab intertidal zone, and subjected to five fixed temperatures: 15, 25, 35, 40 and 45 Cº, after short term thermal acclimation. The heartbeats (HB) were counted at each temperature level. The results showed significant  direct increase of HB from 15 Cº (19.8 HB/min) up to 25 Cº (76 HB/min) (P<0.05)  as well as from 25 Cº to 35 Cº (93 HB/min). At 40 Cº the snail HB

Prior to the start of production, several factors must be considered, including the price, effectiveness, and environmental friendliness of batteries. Ionic liquids and deep eutectic solvents have shown significant success when employed as electrolytes with Titanium-graphite cells, especially when combined with additives that enhance their conductivity by reducing the high viscosity of these liquids. Evaluating the discharge voltage of the AlCl3-chloroacetamide IL with DCM as an additive revealed a voltage of 1.16V and an internal resistance of 11 Ohm. These electrochemical cells exhibited an intriguing response. Otherwise, when utilizing CaCl2.2H2O:

Titanium dioxide (TiO2) nanotubes have gained particular interest as a material for gas sensors because of their vertical arrays, prepared by the anodization procedure. The presence of several oxygen vacancies in these nanotubes facilitates gas diffusion and provides additional active sites. This study examined the impact of voltages on the process of depositing iron nanoparticles onto arrays of TiO2 nanotubes (TNTs) for use as a gas sensor. The TNTs are manufactured using a straightforward and economical electrochemical anodization technique, specifically for gas sensor applications. By varying the deposition voltage (2-6 volts), ordered Fe-TNTs were efficiently manufactured using a simple two-step electrochemical process. It utili

     Titanium dioxide nanotube arrays (TiO2 NTAs) were successfully decorated with nanoclusters of cobalt by an electrochemical deposition method. This Co-TiO2 NTAs nanostructure exhibited high compatibility with aluminum chloride\ chloroacetamide (an ionic liquid) and calcium chloride dihydrate\ acetamide (a deep eutectic solvent), leading to significant improvements in the electrochemical properties of the system. Significantly, this led to a discernible augmentation in both potential and current values, concomitant with a decrease in internal resistance. The presence of cobalt facilitated a faster transfer of electric charge, enhancing the overall efficiency of the system. Moreover, the incorporation of cobalt exhibited a ben
