Calibrating a J2 plasticity material model using a 2D inverse finite element procedure
AbstractMaterial models are the key ingredients to accurately capture the global mechanical response of structural systems. The use of finite element analysis has proven to be effective in simulating nonlinear engineering applications. However, the choice of the appropriate material model plays a big role in the value of the numerical predictions. Such models are not expected to exactly reproduce global experimental response in all cases. Alternatively, the measured global response at specific domain or surface points can be used to guide the nonlinear analysis to successively extract a representative material model. By selecting an initial set of stress–strain data points, the load–displacement response at the monitoring points is computed in a forward incremental analysis without iterations. This analysis retains the stresses at the integration points. The corresponding strains are not accurate since the computed displacements are not anticipated to match the measured displacements at the monitoring points. Therefore, a corrective incremental displacement analysis is performed at the same load steps to adjust for displacements and strains everywhere by matching the measured displacements at the monitoring points. The stress–strain vectors at the most highly stressed integration point are found to establish an improved material model. This model is used within a multi-pass incremental nonlinear finite element analysis until the discrepancy between the measured and the predicted structural response at the monitoring points vanishes. The J2 flow theory of plasticity is used as a constitutive framework to build the tangent elastic–plastic matrices. The applicability of the proposed approach is demonstrated by solving 2D inverse continuum problems. The comparisons presented support the effectiveness of the proposed approach in accurately calibrating the J2 plasticity material model for such problems

The Relation Between Left Thumb Fingerprint Types with Blood Groups and Gender Among Students of Al-kindy College of Medicine, 2019
The skin of the palms and soles is marked by a carved ridge. The pattern of these ridges on the fingers is called dermatoglyphics[1]. In dermatoglyphics, the minute ridge patterns made an impression which has exactly the same arrangement and the pattern of any individual remain unchanged throughout life[2].The friction ridges of all parts of a finger made an impression known as the fingerprint. A friction ridge is a raised section of the epidermis on the digits or on the palmer and plantar skin, composed of one or more connected ridge units of friction ridge skin [3]. Dermatoglyphics is a polygenic trait with Mundelein or single gene inheritance model
Metabolic syndrome and its relationships with adiponectin, vitamin d and physical activity amongadults in an institute of higher learning in the United Arab Emirates
Metabolic syndrome (MetS) is a cluster of risk factors for cardiovascular disease and type 2 diabetes. It is associated with adipose tissue dysfunction resulting from
obesity, an escalating global phenomenon related to lifestyle. Meanwhile,hypovitaminosis D is gaining attention beyond the classical effects on the skeleton. Lifestyle, biochemical and genetic factors are hypothesized to contribute to the pathophysiology of MetS. The aim of this study was to examine the relationships of MetS and its components with adiponectin, vitamin D, VDR gene polymorphisms, and physical activity. The study was conducted from year 2012 until year 2015 in 2 phases
(P-1 and P-2). P-1 (cross-sectional): A total of 235 adults (64 males and 171 females) from the University of Sharjah community were recruited. Anthropometric measures,
biochemical tests (glucose, insulin, lipid profile, vitamin D and HMW adiponectin) and genetic analyses (for VDR gene polymorphisms: TaqI, FokI, and BsmI) were performed.
Demographic profile, habitual dietary intake and exercise perception (Exercise benefits/barriers Scale) were used accordingly. P-2 (interventional): A total of 52 female
participants wore pedometers for 9 weeks after an educational session and goal setting of 10,000 steps per day. All baseline parameters were reassessed post-intervention.The prevalence of MetS was 17.5%; higher in males (OR=10.97, 95%CI: 5.1-23.61, p<0.001) and adults above 40 years old (OR=9.59, 95%CI: 3.98-23.1, p < 0.001). HMW adiponectin was higher in females and in those without MetS; being directly correlated with HDL-cholesterol and inversely correlated with obesity measures and blood pressure. Vitamin D level was 22.49(19.6) nmol/L and only 9.8% had an optimal level.Vitamin D was significantly lower in females [26.6(13.58) nmol/L vs. 34.03(21.34) nmol/L, p < 0.001] and in those without MetS [29.6(18.75) nmol/L vs. 21.06(19.1)nmol/L, p < 0.001] than their counterparts. MetS occurrence was independent of vitamin D status (OR=1.78, 95%CI: 0.65-4.84, p=0.25). The three vitamin D receptor gene polymorphisms did not show any relationship with MetS. However, FokI polymorphisms and F allele in females were associated with higher systolic blood pressure. The participants reported exercise perception benefit/barrier ratio of 1.48. The participants walked 7056±1570 steps per day, recording a marginal increase toward the end of week 9. Small, though, significant reductions were noted in almost all anthropometric parameters and LDL-cholesterol (63.8±18.04 mg/dl vs. 59.17±18.61 mg/dl; p=0.01), while an increase of HMW adiponectin (4.08±0.55 μg/ml vs. 4.15±0.53
μg/ml; p = 0.03) was obtained. An inverse relationship between the number of steps and obesity measures, and positive relation with HMW adiponectin level were evident.
While the number of steps in normal body mass index (BMI) participants was marginally higher (7488.49±1098) than those with higher BMI (6739.18±1793), however, significant improvement was recorded in more measures of body composition variables in participants with higher BMI than those with normal BMI. Similarly, significant improvement in biochemical profiles were observed in participants with high BMI on the level of triglycerides (71.62±29.22 to 62.50±29.16 mg/dl, p=0.003) and insulin levels (21.7±8.33 to 18.64±8.25 μU/l, p=0.046) and increase in HMW adiponectin (3.77±0.46 to 3.80±0.44 μg/ml, p=0.034). In conclusion, the prevalence of MetS was 17.5%, being more common in males. HMW adiponectin could play a role in
the development of MetS while vitamin D and VDR gene polymorphisms could affect the components of MetS. The participants were “low active”, though perceived more
benefits of exercise than barriers. Minimum nominal increase in physical activity can modulate obesity measure, HMW adiponectin and lipid profile with a possible
subsequent decrease of cardiovascular risks, particularly in overweight/obese individuals
Multi-Wall Carbon Nanotubes with NiO and pt as Counter Electrodes for DSSC applications
NiO-MWCNT was synthesized using the hydrothermal method and used as a low-cost, platinum-free counter electrode for Dye-sensitized solar cells DSSCs. The DSSC based on NiO-MWCNT as a counter electrode achieves a high-power conversion efficiency of 8.53% under a simulated solar illumination of 100 mW cm-2 (AM 1.5). This efficiency is comparable to 7.9% for a DSSC equipped with a Pt counter electrode. Good charge conduction characteristics of the NiO-MWCNT electrode decreases charge loss and boosts the effectiveness of converting light into electrical current. The NiO-MWCNT electrode also increases light absorption and increases the efficiency of converting light energy into electrical energy by enhancing light dispersion within the solar cell. Other advantages of NiO-MWCNT electrodes are low cost and great sustainability. Comparing it to platinum, rare and expensive material, the use of NiO-MWCNT reduces the cost of the solar cell and contributes to environmental sustainability. In addition, the NiO-MWCNT electrode has a high chemical stability, making it more resistant to corrosion and damage in dye solar cell environments. This enhances the lifespan of the cell and ensures its long-term sustainability
Adverse Effects of Expansive Soils on Road Infrastructure and Evaluation of Chemical Remediation Techniques
University of Technology Sydney. Faculty of Engineering and Information Technology.Using waste materials and creating novel methods to minimise the adverse effects of expansive soils reduces the cost of building foundations and also reduces their impact on the environment and landfill. Continuous swelling and shrinking cause cracks to form in structures built on expansive soils such as road pavements and embankments. This study describes how a combination of lime and sugarcane bagasse ash, a waste product of the sugar industry, is used to stabilise expansive soils. Since the amount of research addressing the effect of bagasse ash on soil stabilisation was limited, a comprehensive attempt has been made on expansive soils using bagasse ash to improve their engineering properties and reduce the need for traditional additives such as lime. There are large gaps with regards to the optimum amount of bagasse ash that can be used for lime treated soil, the most effective ratio between bagasse and the amount of lime, and the properties of soil treated with bagasse ash, and with or without lime. An array of tests to quantify the shear strength of treated soils, the durability of treated soils using different drying and wetting cycles, and the soil water characteristic curves of treated soils were carried out.
Two types of expansive soils were used in this experimental program; this first type came from a road construction site in Queensland (Soil Q) and is classified as a high plasticity clay; the second type was created in the laboratory by mixing 80% kaolin and 20% bentonite (Soil C). It was also defined as high plasticity clay. These samples were prepared by integrating soil with a mixture of hydrated lime (L) from 0 to 6.25% and up to 25% of bagasse ash. These combinations of lime to bagasse ash were prepared with different ratios (e.g. 1:1, 1:2, 1:3 and 1:4). A combination of lime and bagasse ash was added to the soil samples as a stabiliser at ratios of 6%, 10% 18% and 25%, based on the dry weight of soil. To determine how hydrated lime and bagasse ash affects the engineering properties of treated soils, tests such as particle size distribution, specific gravity, Atterberg limits, compaction, linear shrinkage, the free swell ratio, unconfined compressive strength (UCS), durability, the California bearing ratio (CBR), free swell, swell pressure, consolidation, and direct shear and suction tests were carried out.
The results indicate that the dry density of natural and artificial soils decreases as the amount of additives increase, and the linear shrinkage, free swell ratio, free swelling and swell pressure of soils treated with a combination of lime and bagasse ash decreased more than soils treated only with lime or bagasse ash. The UCS and CBR of soil increased as the amount of additives and curing time increased, and when bagasse ash was added to soil treated with lime under various cycles of wetting-drying, it became more durable than soil treated just with lime. Moreover, the addition of bagasse ash to soil treated with lime reduced the gap between soaked and unsoaked CBR. The pre-consolidation pressure (′), the coefficient of consolidation (), the compression index (), the swell index (), and the cohesion and friction angle of soils improved as the amount of additives (bagasse ash and/or lime) increased. The matric suction was determined based on the gravimetric water content and degree of saturation, using the filter paper technique. The air entry value parameter () of soils increased after adding 6.25% lime, but the highest value was for soil samples treated with 6.25% L and 18.75% BA.
PLAXIS software was used to calculate the deformation and to evaluate the slope stability of a proposed embankment placed on top of the target expansive soil (Soil Q) under a fill embankment. Five models were developed to estimate the settlement of soil and assess the slope stability of a fill embankment under traffic loads. The Mohr-Coulomb model was used to simulate a fill embankment as well as treated soil and dense sand, while a soft soil model was applied to untreated soil with an over consolidation ratio of 1.2. These numerical models indicated that treating soil reduced its vertical displacement (settlement) due to an increase in its strength parameters, whereas the reduction in time is associated with an increase in its permeability. The slope stability of the fill embankment decreased slightly as the layer of treated soil was made thicker.
This study offers a promising way of using bagasse ash as an eco-friendly stabiliser for treating expansive soils, particularly in conjunction with lime for treatment of weak subgrade of roads
Effects of IVF therapies on metabolic, endocrine and inflammatory status in IVF-conceived pregnancy
Rationale
In vitro fertilization (IVF) is a common treatment for infertility. In mice, IVF is associated with development of glucose intolerance. However, human data are limited regarding the metabolic, endocrine and inflammatory effects of IVF therapy in IVF‐conceived pregnancies.
Objective
To explore effects of IVF therapies on metabolic, endocrine and inflammatory parameters in IVF‐conceived pregnancy.
Methodology
Twelve‐week prospective observational study of adult normoglycaemic women, BMI 18.5‐38 kg/m2 and ≤ 39 years awaiting IVF therapy. Fasting blood samples were collected at baseline and 12 weeks, and serum analysed for reproductive hormones, glucose, lipids, insulin sensitivity, thyroid status, adiponectin inflammatory marker and lipopolysaccharide‐binding protein (LBP).
Results
Two hundred and seventy‐five women were analysed: 158 IVF‐conceived pregnant women and 117 with failed IVF. Compared with baseline, nonpregnant women had significant (P < .001) increases in 12‐week glucose (86.04‐87.62 mg/dL), insulin (8.72‐9.37 µIU/mL), HOMA‐IR (1.9‐2.1), T‐Chol (169.5‐174.9 mg/dL), TG (71.0‐83.7 mg/dL) and HDL‐C (52.0‐54.11 mg/dL) levels. At 12 weeks, pregnant women also had (P < .001) increases in T‐Chol (177.5‐199.5 mg/dL), TG (73.5‐126.78 mg/dL) and HDL‐C (55.3‐65.1 mg/dL), while a significant reduction in glucose (86.15‐82.19 mg/dL), HbA1c (5.3‐5.08%) and TSH (1.71‐1.36 µIU/mL) levels from baseline. Adiponectin and LBP levels remained the same in either group.
Conclusion
In vitro fertilization hormonal therapy impairs glucose and insulin levels; these effects are masked in early pregnancy. Changes in lipid profile occur following IVF therapies regardless of pregnancy outcome. Neither adiponectin nor LBP is affected by IVF therapies and during early IVF‐conceived pregnancy
Design and implementation of proposed 320 bit RC6-cascaded encryption/decryption cores on altera FPGA
This paper attempts to build up a simple, strong and secure cryptographic algorithm. The result of such an attempt is “RC6-Cascade” which is 320-bits RC6 like block cipher. The key can be any length up to 256 bytes. It is a secret-key block cipher with precise characteristics of RC6 algorithm using another overall structure design. In RC6-Cascade, cascading of F-functions will be used instead of rounds. Moreover, the paper investigates a hardware design to efficiently implement the proposed RC6-Cascade block cipher core on field programmable gate array (FPGA). An efficient compact iterative architecture will be designed for the F-function of the above algorithm. The goal is to design a more secure algorithm and present a very fast encryption core for low cost and small size applications
