Effect of Bond-Slip on Dynamic Response of FRP-Confined RC Columns with Non-Linear Damping
Authors: Guo Kun , Guo Qirui , Wang Yuanfeng
Published: February 2021

As a composite material, the damping energy consumption mechanism of fiber reinforced polymer-confined reinforced concrete (FRP-C RC) structure is very complex. In previous dynamic calculation models, the bond-slip effect for steel bars was often ignored, which would lead to a considerable error in the response of the FRP-C RC structures. In this paper, a new numerical model of FRP-C RC columns considering the bond-slip for steel bars is established using a zero-length element and nonlinear beam-column elements in the OpenSees software, and the results of the model are verified by experimental results. Based on the complex damping theory, the loss factor expression and nonlinear damping model of FRP-C RC columns with the bond slip effect are proposed. Finally, the dynamic response of FRP-C RC columns with nonlinear damping under harmonic load is calculated and compared with the results available in literature. The results show that the proposed model considering steel bars’ bond-slip can provide better prediction for dynamic response of FRP-C RC columns and make the future seismic design of FRP-C RC columns safer.

Published: February 2021

The objective of this study was to enhance dissolution and permeation of a low soluble, absorbable fexofenadine hydrochloride (FFH) by preparing solid dispersions using polyethylene glycol 20,000 (PEG 20,000) and poloxamer 188 as carriers. The phase solubility measurement for the supplied FFH revealed a linear increase in the solubility of fexofenadine with increasing carrier concentration in water (1.45 mg/mL to 11.78 mg/mL with 0% w/v to 30% w/v PEG 20,000; 1.45 mg/mL to 12.27 mg/mL with 0% w/v to 30% w/v poloxamer 188). To select the appropriate drug carrier concentration, a series of solid dispersions were prepared in the drug carrier weight ratios of 1:1, 1:2 and 1:4 by fusion method. The solid dispersions composed of drug carrier at 1:4 weight ratio showed highest dissolution with the time required for the release of 50% of the drug <15 min compared to the supplied FFH (>120 min). The intestinal absorption study presented a significant improvement in the absorption of drug from the solid dispersions composed of poloxamer 188 than PEG 20,000. In summary, the solid dispersions of FFH prepared using PEG 20,000 and poloxamer 188 demonstrated improved dissolution and absorption than supplied FFH and could be used to improve the oral bioavailability of fexofenadine.

Published: February 2021

The rational design of carbon nanomaterials-reinforced polymer matrix composites based on the excellent properties of three-dimensional porous materials still remains a significant challenge. Herein, a novel approach is developed for preparing large-scale 3D carbon nanotubes (CNTs) and graphene oxide (GO) aerogel (GO-CNTA) by direct grafting of CNTs onto GO. Following this, styrene was backfilled into the prepared aerogel and polymerized in situ to form GO–CNTA/polystyrene (PS) nanocomposites. The results of X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy indicate the successful establishment of CNTs and GO-CNT and the excellent mechanical properties of the 3D frameworks using GO-CNT aerogel. The nanocomposite fabricated with around 1.0 wt% GO-CNT aerogel displayed excellent thermal conductivity of 0.127 W/m∙K and its mechanical properties were significantly enhanced compared with pristine PS, with its tensile, flexural, and compressive strengths increased by 9.01%, 46.8%, and 59.8%, respectively. This facile preparation method provides a new route for facilitating their large-scale production.

Published: February 2021

G. procumbens is an herbaceous medicinal plant. Despite the progressive reports on the potential pharmacological properties, many are overlooking at the importance of its agronomic requirements, especially in fertilization to produce high yields which have not been conclusively concluded. This study was carried out to examine the effects of nitrogen on growth quality. In this study of two factors, harvesting times and rate of nitrogen, a total of 12 combined treatments replicated three times with 108 plants were laid out according to randomized complete block design. Growth attributes were recorded in three harvests of triplicate samples to exhibit the trend for plant growth and quality, and statistically analysed. Nitrogen affected plant growth significantly (p≤0.05) with stronger effect on physiological attributes (p≤0.01). The results suggested that 0 nitrogen kg/ha at Week 12 and 90 nitrogen kg/ha at Week 4 is highly and least, respectively affected the morphology and physiology of G. procumbens. These attributes are controlled by the availability of usable nitrogen and agronomic management because nitrogen is needed in optimum quantity and must be in balance with other nutrients to achieve its maximum yield potential.

Difficulties to use convenient data during the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) pandemic outbreak and complexities of the problem attitude crucial challenges in infectious disease modelling studies. Motivated by the on-going reach to predict a potential reactivated SARS-CoV-2 (COVID-19), we suggest a prediction model that beyond the clinical characteristics based evaluation approaches. In particular, we developed a possibly available and more efficient prediction model to predict a potential reactivated SARS-CoV-2 (COVID-19) patient. Our paper aims to explore the applicability of a modified Technique for Order Preference by Similarity to Ideal Solutions (MTOPSIS) integrated Design of Experiment (DoE) method to predict a potential reactivated COVID-19 patient in real-time clinical or laboratory applications. The presented novel model may be of interest to the readers studying similar research areas. We illustrate MTOPSIS integrated DoE method by applying it to the COVID-19 pandemic real clinical cases from Wuhan/China-based data. Despite the small sample size, our study provides an encouraging preliminary model framework. Finally, a step by step algorithm is suggested in the study for future research perspectives.

Authors: EYECİOGLU Önder , KARABUL Yaşar , KILIÇ Mehmet , GÜVEN ÖZDEMİR Zeynep
Published: February 2021

The present study deals with the application of the supervised machine learning regression algorithms known as Linear Regression (LR), Support Vector Machine (SVM), and Gaussian process regression (GPR) to the frequency and temperature-dependent dielectric parameters of polymer/inorganic film composites. The frequency and temperature-dependent experimental data set of the dielectric parameters (ε^' and ε^'') of Polypyrrole/Kufeki Stone (PPy/KS) has been utilized. ML models were compared based on their model performance and the most suitable was chosen. After choosing the most suitable ML model, at first, the predictions of the same dielectric parameters of the same samples for different temperatures have been made. Then, the predictions of temperature and frequency-dependent ε^' and ε^'' have been performed for the new PPy based composites consisting of different KS additives that were not produced experimentally. As a result of machine learning, the saturation for KS reinforcing material weight % for dielectric parameters has been determined for capacitor applications. In the light of experimental data and the estimations made by the GPR algorithm, some specific KS additive percentage, working temperature, and frequency ranges have been suggested for the capacitor applications of PPy.

Published: February 2021

This article considers an approach to achieving modifiability of design solutions in the form of digital 3D parts and assembly units in CAD systems. This approach is based on a modular principle, according to which a design solution is represented by a system of 3D macro-objects. Such macro-objects are typical of a given subject area, have semantic content and are described by a set of design parameters. The variability of selected parameters forms a class of design solutions, which, although differing in terms of geometry and structure, have common structural and functional specific features. The main advantage of the proposed approach consists in the provision of the semantic integrity of a design solution during its modification and reuse.

Published: February 2021

Hemorrhagic cholecystitis is a potentially deadly and difficult to recognize entity. It is associated with cystic artery pseudoaneurysm and is usually seen in the setting of acute calculous cholecystitis. We report two cases of hemorrhagic cholecystitis with arteriographic findings of cystic artery pseudoaneurysms that were successfully embolized using microcoils, facilitating subsequent cholecystectomy. Both cases had unusual presentations of gallbladder rupture with hemoperitoneum, the latter of which was atypical occurring in the absence of gallstones. We believe when hemorrhagic cholecystitis is suspected, a two-step therapeutic approach should be employed with embolization of the bleeding cystic artery followed by cholecystectomy. A comprehensive literature review and discussion of hemorrhagic cholecystitis will be provided.

Authors: Ram Shruthi , Dietsche Eric
Published: February 2021

The evolving nature of newer surgical techniques and devices adds to the challenge of interpreting breast imaging in the post lumpectomy setting. The BioZorb surgical marker placed at lumpectomy sites for post-operative radiation targeting has its own distinct imaging appearance on each modality. Determining the expected follow-up imaging findings unique to this relatively new device is an ongoing endeavor with literature currently lacking on this topic. The following series of cases of post BioZorb breast surveillance are the first reported in the literature to provide examples of developing asymmetries and new or enlarging masses adjacent to the BioZorb site along with the final pathologic diagnosis for each case. Pathology findings range from fat necrosis and foreign body reaction to recurrent disease.

Aqueous extracts (2%) of three plants; roselle (Hibiscus subdariffa Linn.), cinnamon (Cinnamomum verum J. Presl.) and clove (Syzygium aromaticum Linn.) were assessed for control of citrus canker disease in lime (Citrus aurantifolia Swingle) caused by Xanthomonas axonopodis pv. citri (Xac) under in vitro and in vivo conditions. Mancozeb fungicide (1.5%) was used as a positive control. In the first experiment, the effect of these three plant extracts was investigated in vitro through inhibition zone technique. Results indicated that roselle and cinnamon extracts caused significantly less inhibitory effect (38.5% and 25%, respectively) on canker severity compared to the fungicide Mancozeb (control), but they were significantly (P ≥ 0.05) more efficacious than clove extract. Clove extract showed little or no in vitro inhibitory activity. In the second experiment conducted in a greenhouse with natural infection of Xac on lime seedlings, aqueous extracts (2%) of roselle, cinnamon and clove significantly (P ≥ 0.05) exhibited an inhibitory effect against the disease severity with a decline from 40.4 to 45.2%. Roselle extract was the most effective for control of citrus canker (45.2%) followed by cinnamon and clove which recorded only 40.4% disease control after three weeks compared to the control treatment.

Organic and inorganic fertilizers improve soil fertility and give both macro and micronutrients to the soil for better growth of agricultural crops. Therefore, current study was designed to find out the efficacy of inorganic phosphorus (P) alone and in combination farmyard manure (FYM) applied in various doses on production and quality aspects of garlic. A field experiment was organized in a randomized complete block design, replicated thrice using different rates of P in the form of single super phosphate (SSP) and farmyard manure (FYM). Seven different treatments of various levels of P, either using inorganic phosphorus from SSP alone or in combination with organic phosphorus from FYM, i.e. T0 = control; T1 = 50 kg P.ha-1 (SSP); T2 = 70 kg P.ha-1 (SSP); T3 = 90 kg P.ha-1 (SSP); T4 = 25 kg P.ha-1 (SSP) + 25 kg P.ha-1 (FYM); T5 = 35 kg P.ha-1 (SSP) + 35 kg P.ha-1 (FYM); T6 = 45 kg P.ha-1 (SSP) + 45 kg P.ha-1 (FYM)] were applied to the soil. All the growth, yield and quality parameters recorded showed significant response when P was applied in combination of inorganic and organic sources as compared with control and inorganic P alone. A combined treatment of 45 kg P.ha-1 (SSP) + 45 kg P.ha-1 (FYM) gave comparatively better results in terms of plant height (66.87 cm), fresh leaf weight (2.70 g), leaf area plant-1 (83.83 cm2), relative leaf chlorophyll content (11.90), weight of bulb plant-1 (42.66 g), diameter of bulb (4.50 cm), number of cloves bulb-1 (8.50), bulb yield (4382.96 kg ha-1) and vitamin C content (6.43 mg 100 g-1). Thus, it was concluded from this study that a combined treatment of 45 kg P.ha-1 (SSP) + 45 kg P.ha-1 (FYM) should be applied for quality production of garlic under rainfed conditions of Rawalakot.
Measurement of Radon (222Rn) Concentrations in the Basaltic Rocks of Yarmouk River, Jordan
Authors: Hamed Raja'
Published: February 2021

This article was conducted to measure radon concentration levels in the Yarmouk River Basalt (YRB), North-Jordan. The YRB is of Quaternary in age and occurred as a successive sheet with a total thickness of 122 meters. The Yarmouk River Basalt is classified into four major phases. Namely, Yarmouk Sheet basalt, Yarmouk blocky basalt, Yarmouk massive basalt, and Yarmouk exfoliated. Furthermore, each major phase is subdivided into several flows. Sixteen samples are measured by using Nuclear Track Detector (Columbia Resin CR-39) in the laboratory. The results show that the concentration of radon is gradually decreased from the lower basalt first phase towards the upper fourth phase in considerable amounts. The values range from 12413.12 to 4137.71 Bq/m3, with an average value of 6635.74 Bq/m3. The results of this investigation indicate that the uranium isotopes element decay is the origin of radon emitted from the interstitial glass in the basalt rocks, rather than 222Rn emission along with fractures or major faults.
Facies Analysis and Depositional Stages of The Albian-Aptian Succession in Balad Oil Field, Central Iraq
Authors: Amer Zainab
Published: February 2021

Carbonate-clastic succession which includes the Shu'aiba, Nahr Umr and Mauddud formations are representing a part of the Barremian-Aptian Sequence (Wasi'a Group). The present study includes three boreholes (Ba-1, 4 and 8) within the Balad Oil Field. The study area is located in central Iraq. This field represents a subsurface anticline with a northwest to southeast direction axis within the Mesopotamian Zone. Eight types of microfacies were recognized in the succession of the Mauddud and Shu’aiba formations. These microfacies represent shallow open marine, restricted and semi-restricted, reef - back reef, deep open marine and basinal depositional environments. While Nahr Umr Formation includes two successions, the first is the upper unit which is characterized by shale dominated rocks and the second is the lower unit which is characterized by sand-dominated rocks. Four major lithofacies were recognized in these two successions, they represent four depositional environments which are distributary channel, bay fill, delta plain and prodelta. The Albian-Aptian sequence was deposited during three cycles overlying the regional unconformity below the Shu’aiba Formation, the Zubair Formation, and ended with local unconformity with the Ahmadi Formation. The first stage is represented by deposition of Shu’aiba Formation during the sea-level rise after regression stage during the Zubair deposition which deposition in delta association facies. The second stage was showed a regressed of deposit the delta system above the shallow open marine of the Shu’aiba Formation, where the succession became characterized by mud-dominated rock with fissile and organic material. The third depositional stage is represented by the continuation of sea-level rise. This transgression leads to the building of carbonate ramp of the Mauddud Formation above the deltaic system of Nahr Umr Formation with a conformable surface. The Mauddud depositional stage was represented by two cycles of transgression succession, where appeared deepening upward in both cycles. The unconformity between these formations have been determined by observing the glauconite mineral and detected by log response in depth 2880m in well Ba-1.

The study focused on two important sites containing many caves sites located in the west of Al Anbar Governorate. The first site is Um El-Githoaa cavity in Hit region, a cave or trunks was chosen to show the aesthetic of this cave in terms of its shape and dimensions. The maximum diameter is 22.1m, while the perpendicular diameter is 18.5m. It is a dome shape and the height of its roof reaches about 2m located in the stratigraphic sequence falls within the massive gypsum, Fatha Formation (Middle Miocene). Geoelectrical exploration was chosen on the southern side of the cave to check whether the sinkholes scattered in the area are connected to subsurface caves or not. Using a Dipole-dipole array was chosen along a traverse, shown there are three sub-surface caves. This indicates that these phenomena are widespread in the region. The second location is Haditha, Barwana Village which was chosen to study where the cave is located in unconformity breccia zone between Anah Formation (Upper Oligocene- Lower Miocene) and Euphrates Formation (Lower Miocene- Middle Miocene). Barwana cave extends to the north 30 m and then tends to the west extend about 1 km within fragile breccia layer with incoherent components and ends with a small opening at the Euphrates River. This phenomenon was not present in the hard gypsum rocks in the Hit region, it was observed to have a large oval shape

Authors: Hussain Salah
Published: February 2021

The Qamchuqa Formation was studied in Chwarqauran section, Sulaimanyia, Kurdistan region, Northeastern Iraq. The lithology of the formation contains limestone throughout the whole section except for one bed of dolomite at the Middle part. Twenty-four slides were prepared from 24 rock samples that were taken from this section to discriminate the petrography and fossil content. The petrographic study shows four main microfacies including lime mudstone, wackestone, packstone, and floatstone. Additionally, there are four sub microfacies: bioclast wackestone, miliolid wackestone, bioclast packstone and orbitolinid packstone. However, the fossil content shows the abundance of benthic foraminifera against the planktonic. All the microfacies indicate facies zone 7, 8 and 9A which reflect deposition in the platform interior between the tidal flat to the mid ramp and back reef environment
Evaluación de las interacciones de las comunidades urbanas y rurales con el capital natural de la parte alta de la microcuenca del río Riachuelo de Zacapa, Guatemala

Una forma de evaluar los beneficios y valor ecológico y de ecosistemas que emplean las poblaciones humanas es estudiarlas desde el concepto de capital natural. El término capital natural se emplea para referirse al acervo o conjunto de recursos renovables y no renovables como las plantas, animales, aire, agua, suelos, minerales; que se combinan para proporcionar un flujo de beneficios a la humanidad. Este término también se puede definir como el acervo mundial de activos que incluyen geología, suelos, aire, agua, y todos los seres vivos.

El término capital natural es una extensión de la noción económica de capital de bienes y servicios provenientes del medio natural, hay que tomar en cuenta que los ecosistemas son sistemas abiertos, que se conectan a distintos niveles y lo que pasa a una escala local tiene implicaciones o efectos a escala global y viceversa. Se comprobó la hipótesis los capitales naturales que emplean con más frecuencia y su nivel de importancia varía según la ubicación y contexto social a lo largo de la cuenca del Río Riachuelo, en Zacapa, Zacapa. Los cinco bienes y servicios ecosistémicos de mayor importancia para la comunidad de Guadalupe por ejemplo fueron el agua, la leña, el ocote (subproducto de Pinus maximinoi), la hierbabuena, la miel de abeja grande. En Pinalito fueron el agua, la leña, el sol, el aire, maíz. En Zacapa el agua, la leña, el ocote, la miel de Apis mellifera y la hierbabuena y en El Terrero, el agua, la leña, la hierbamora, el mango y la miel de Apis mellifera. Cabe resaltar que en todas las comunidades visitadas el agua es un bien muy importante, al igual que la leña y el ocote.
