Characterization of gas permeation in the pores of Zn(II)-based metal organic framework (MOF)/polymer composite membranes

ABSTRACT The separation of greenhouse gases from industrial processes is an ongoing focus for research aimed at mitigating environmental impacts. As a result, it is important to develop experimental techniques for the characterization of the transport of gases through porous crystalline materials with potential applications in gas separations. We report on the fabrication and characterization of gas transport in supported Zn(II)-based MOF membranes. The MOF membranes were used to develop an approach to study membrane quality and determine the transport mechanism through the pores of the crystalline membrane. Membranes were synthesized via a solvothermal method with structural defects sealed by a low-permeability polymer coating, allowing for the measurement of permeation in materials that do not form uniform, defect-free films. Membrane permeation was proportional to the inverse square root of the molecular weight of the permeant gases, indicating that diffusion occurs via Knudsen diffusion. Membrane quality was studied via selectivity measurements as a function of temperature. A study of the gas permeation through a polymer coated sparse MOF membrane, was used to confirm that gas transport occurs through the pores of the MOF, rather than through pinholes or defects in the structure.
Effect of dry-wet cycles on carbon dioxide release from two different volcanic ash soils in a Japanese temperate forest

ABSTRACT In the present study, two volcanic ash soils (soil A and B) from a temperate broad-leaved forest in eastern Japan were aerobically incubated under repeated dry-wet cycles and continuously constant moisture conditions. The primary aims were to quantify the potential for enhancement of carbon dioxide (CO2) release owing to increased water fluctuation and to examine differences in the responses of volcanic ash soils with different physicochemical properties. Soil B, rather than soil A, was a typical Andosol. During incubation at 20°C for 120 days with five dry-wet cycles, the CO2 release rate was measured periodically. Abundance of the stable carbon isotope in CO2 (δ13C-CO2) was measured to capture changes in the origin of decomposed soil organic matter (SOM) owing to the dry-wet cycles. The CO2 release rate under the dry-wet cycles was up to 49% higher than the values predicted from a parabolic relationship between CO2 release and water content during incubation under the continuously constant moisture condition. The magnitude of CO2 release enhancement was 2.7-fold higher in soil B relative to that in soil A. The δ13C-CO2 value in the dry-wet cycles was enriched by 0.3–2.3‰ compared to that during incubation under the continuously constant moisture conditions, suggesting that the decomposition of well-metabolized and/or old SOM was enhanced by the dry-wet cycles. Thus, the present study suggests that Andosols, which have been believed to have a strong SOM stabilization ability, are vulnerable to dry-wet cycles. Then, increased water fluctuation in a future warmer world would have significant potential to stimulate CO2 release from soils.
Happy Jack Uraninite: A New Reference Material for High Spatial Resolution Analysis of U‐Rich Matrices

There is currently a lack of well‐characterised matrix‐matched reference materials (RMs) for forensic analysis of U‐rich materials at high spatial resolution. This study reports a detailed characterisation of uraninite (nominally UO2+x) from the Happy Jack Mine (UT, USA). The Happy Jack uraninite can be used as a RM for the determination of rare earth element (REE) mass fractions in nuclear materials, which provide critical information for source attribution purposes. This investigation includes powder X‐ray diffraction (pXRD) data, as well as major, minor and trace element abundances determined using a variety of micro‐analytical techniques. The chemical signature of the uraninite was investigated at the macro (cm)‐scale with micro‐X‐ray fluorescence (µXRF) mapping and at high spatial resolution (tens of micrometre scale) using electron probe microanalysis (EPMA) and laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) analyses. Based on EPMA results, the uraninite is characterised by homogeneous UO2 and CaO contents of 91.57 ± 1.49% m/m (2s uncertainty) and 2.70 ± 0.38% m/m (2s), respectively. Therefore, CaO abundances were used as the internal standard when conducting LA‐ICP‐MS analyses. Overall, the major element and REE compositions are homogeneous at both the centimetre and micrometre scales, allowing this material to be used as a RM for high spatial resolution analysis of U‐rich samples.
Formulation, Development and Characterization of Ethosomes of Atorvastatin

Objectives: The main objective of the present investigation was to develop transdermal delivery of Atorvastatin, a HMG-CoAreductase inhibitor used in the treatment of congestive heart failure (CHF). Atorvastatin was formulated into ethosomal formulation to reduce the first pass metabolism and increase the systemic bioavailability. Methods: Cold method was used to formulate ethosomes by using suitable phosphatidylcholine and permeation enhancer. All the formulation were characterized for vesicle morphology, particle size and entrapment efficiency by Transmission Electron Microscopy, Differential light scattering and centrifugation respectively. The effect of different formulation variable on skin permeation of Atorvastatin was studied via synthetic semipermeable membrane or skin of new born mice by using diffusion cell. Results: The optimized ethosomal formulation showed enhanced drug delivery with no first pass metabolism, entrapment efficiency was found to be 98.65 ± 0.63% and showed drug release 98.13 ± 3.67% for ethosomal formulation across rat skin as compared to 52.37 ± 3.62% for hydroethanolic solution. Conclusion: Finally it was concluded from the study that, ethosomes can increase the transdermal flux, prolong the release and present an attractive route for sustained delivery of Atorvastatin.
MiR-378a-5p Regulates Proliferation and Migration in Vascular Smooth Muscle Cell by Targeting CDK1

Objective: Abnormal proliferation or migration of vascular smooth muscle cells (VSMCs) can lead to vessel lesions, resulting in atherosclerosis and in stent-restenosis (IRS). The purpose of our study was to establish the role of miR-378a-5p and its targets in regulating VSMCs function and IRS. Methods: EdU assays and Cell Counting Kit-8 (CCK-8) assays were applied to evaluate VSMCs proliferation, wound healing assays and transwell assays were applied to assess cells migration. Furthermore, quantitative reverse transcription–polymerase chain reaction (qRT-PCR) was performed to investigate the expression level of miR-378a-5p IRS patients and healthy individuals. Target genes were predicted using Target Scan and miRanda software, and biological functions of candidate genes were explored through bioinformatics analysis. Moreover, RNA-binding protein immunoprecipitation (RIP) was carried out to analyze the miRNAs interactions with proteins. We also used Immunofluorescence (IF) and fluorescence microscopy to determine the binding properties, localization and expression of miR-378a-5p with downstream target CDK1. Results: The expression of miR-378a-5p was increased in the group with stent restenosis compared with healthy people, as well as in the group which VSMCs stimulated by platelet-derived growth factor-BB (PDGF-BB) compared with NCs. MiR-378a-5p over-expression had significantly promoted proliferative and migratory effects, while miR-378a-5p inhibitor suppressed VSMC proliferation and migration. CDK1 was proved to be the functional target of miR-378a-5p in VSMCs. Encouragingly, the expression of miR-378a-5p was increased in patients with stent restenosis compared with healthy people, as well as in PDGF-BB-stimulated VSMCs compared with control cells. Furthermore, co-transfection experiments demonstrated that miR-378a-5p over-expression promoted proliferation and migration of VSMCs specifically by reducing CDK1 gene expression levels. Conclusion: In this investigatory, we concluded that miR-378a-5p is a critical mediator in regulating VSMC proliferation and migration by targeting CDK1/p21 signaling pathway. Thereby, interventions aimed at miR-378a-5p may be of therapeutic application in the prevention and treatment of stent restenosis.

En el experimento 2 se aplicaron los siguientes tratamientos: TES) dieta sin ET, TC) 0.6% de taninos condensados y TH) 0.6 % de taninos hidrolizables a la dieta de 18 becerros (220±9 kg) durante 28 dias. En los dos experimentos las heces obtenidas se incubaron durante 24 h para medir su produccion de gas por desplazamiento. Los datos obtenidos de gas se compararon con Diseno experimental de bloques al azar para eliminar el efecto dia de muestreo. En el primer experimento la produccion de gas disminuyo 44 % (P<0.001) con los extractos de taninos adicionados sobre las heces, pero adicionados a traves de la dieta no hubo diferencias entre los tratamientos.
Amphiphilic-Polymer-Assisted Hot Water Flooding toward Viscous Oil Mobilization

Heavy oil recovery is the most challenging part for the petroleum industry, and several techniques including steam and water injection are currently used that are either energy intensive, expensive, or less efficient. This study aims to evaluate a novel amphiphilic viscosity reducing polymer (DN-1) used along with hot water flooding for promoting viscous oil mobilization. Its performance for heavy oil mobilization was evaluated using viscosity measurements at different temperatures followed by core flooding experiments. Our results indicate that DN-1 at low concentrations could form 3D networks and stable aggregates. DN-1 featured good interfacial properties including low CMC, low IFT, and small contact angle. Even at low concentration it could form dynamic oil in water emulsions, thereby causing easy emulsification and fast demulsification. The injection pressure of DN-1 was much smaller than that of the conventional polymers or associative polymers used for heavy oil development and is beneficial for oi.

Dwarf Frankenstein is still in your memory: tiny code reuse attacks

Code reuse attacks such as return oriented programming and jump oriented programming are the most popular exploitation methods among attackers. A large number of practical and non-practical defenses are proposed that differ in their overhead, the source code requirement, detection rate and implementation dependencies. However, a usual aspect among these methods is consideration of the common behaviour of code reuse attacks, which is the construction of a gadget chain. Therefore, the implication of a gadget and the minimum size of an attack chain are a matter of controversy. Conservative or relaxed thresholds may cause false positive and false negative alarms, respectively. The main contribution of this paper is to provide a tricky aspect of code reuse techniques, called tiny code reuse attacks (Tiny-CRA) that demonstrates the ineffectiveness of the threshold based detection methods. We show that with bare minimum assumptions, Tiny-CRA can reduce the size of a gadget chain in shuch a way that no distinction can be detected between normal behavior of a program and a code-reuse execution. To do so, we exhibit our Tiny-CRA primitives and introduce a useful gadget set available in libc. We demonstrate the effectiveness of our approach by implementing nine different shell-codes and exploiting real-world buffer overflow vulnerability in HT Editor 2.0. 20.
High-Solubility Salts of the Multiple Sclerosis Drug Teriflunomide

Teriflunomide (TFM) is an immunomodulatory prodrug of leflunomide which is used for the treatment of multiple sclerosis (MS). It is a Biopharmaceutics Classification System Class (BCS) II drug with low solubility and high permeability. The X-ray crystal structure of TFM is stabilized by O–H···O, C–H···O, C–H···N, and N–H···N interactions. In order to study the solubility and dissolution changes of this drug, five multicomponent crystal forms were prepared with amine and amide generally regarded as safe (GRAS) coformers to improve the physicochemical properties such as solubility, dissolution, diffusion, and phase stability. Equimolar TFM–coformer 1:1 salts were crystallized, except for cytosine which afforded a salt cocrystal toluene solvate TFM–CYT–TOL in a 1:2:1 ratio. The multicomponent forms were crystallized by slow solvent evaporation and characterized by single crystal X-ray diffraction. TFM and coformer are bonded by N+–H···O–, N–H···O, O–H···O, C–H···O, C–H···N, N–H···N, and C–H···F interactions.
Fusión de información de geometría e intensidad para segmentación de imágenes TOF

Resumen. Las cámaras de tiempo de vuelo (TOF) generan dos imágenes simultáneas, una de intensidad y una de rango. Esto permite abordar problemas de segmentación donde la información de intensidad o de rango separadamente es insuficiente para extraer los objetos de interés de la escena 3D. A su vez, la información de rango permite obtener una aproximación del vector normal de cada punto de las superficies capturadas. En este art́ıculo se presenta un método de segmentación espectral, que combina la información de intensidad, de rango y las orientaciones de los vectores normales para mejorar los resultados de la segmentación. Los agrupamientos obtenidos suponen una estructura subyacente común entre todas las fuentes de información, llamadas vistas. Se utilizan técnicas de clustering espectral co-regularizado para obtener agrupamientos que sean consistentes de acuerdo a todas las vistas. La evaluación del método propuesto fue realizado sobre imágenes reales. El rendimiento obtenido al combinar las tres fuentes de información presenta mejoras en los agrupamientos resultantes.
Preserving Privacy in High-Dimensional Data Publishing

We are witnessing a continuous expansion of information technology that never ceases to impress us with its computational power, storage capacity, and agile mobility. Such technology is becoming more pervasive by the day and has enhanced various aspects of our daily lives. GPS-equipped devices, smart card automated fare collection systems, and sensory technology are but a few examples of advanced, yet affordable, data-generating technologies that are an integral part of modern society. To enhance user experience or provide better services, service providers rely on collecting person-specific information from users. Thus, the collected data is studied and analyzed in order to extract useful information. It is a common practice for the collected data to be shared with a third-party, e.g., a data mining firm, for data analysis. However, the shared data must not leak sensitive information about the individuals to whom the data belongs or reveal their identity. In other words, individuals’ privacy must be protected in the published data. Privacy-preserving data publishing is a research area that studies anonymizing person-specific data without compromising its utility for future data analysis. This thesis studies and proposes anonymization solutions for three types of high-dimensional data: trajectory streams, static trajectories, and relational data. We demonstrate through theoretical and experimental analysis that our proposed solutions, for the most part, outperform state-of-the-art methods in terms of utility, efficiency, and scalability.
The epidural needle guidance with an intelligent and automatic identification system for epidural anesthesia

Incorrect placement of the needle causes medical complications in the epidural block, such as dural puncture or spinal cord injury. This study proposes a system which combines an optical coherence tomography (OCT) imaging probe with an automatic identification (AI) system to objectively identify the position of the epidural needle tip. The automatic identification system uses three features as image parameters to distinguish the different tissue by three classifiers. Finally, we found that the support vector machine (SVM) classifier has highest accuracy, specificity, and sensitivity, which reached to 95%, 98%, and 92%, respectively.
Ultra-Wideband CMOS Transceiver Front-End for Bio-Medical Radar Sensing

Since the Federal Communication Commission released the unlicensed 3.1-10.6 GHz frequency band for commercial use in early 2002, the ultra wideband (UWB) has developed from an emerging technology into a mainstream research area. The UWB technology, which utilizes wide spectrum, opens a new era of possibility for practical applications in radar sensing, one of which is the human vital sign monitoring. The aim of this thesis is to study and research the possibility of a new generation humanrespiration monitoring sensor using UWB radar technology and to develop a new prototype of UWB radar sensor for system-on-chip solutions in CMOS technology. In this thesis, a lowpower Gaussian impulse UWB mono-static radar transceiver architecture is presented. The UWB Gaussian pulse transmitter and receiver are implemented and fabricated using 90nm ST CMOS technology. Since the energy of low order Gaussian pulse is mostly condensed at lower frequency, in order to transmit the pulse in a very efficient way, higher order Gaussian derivative pulses are desired as the baseband signal. This motivates the advancement of the design into UWB high-order pulse transmitter. Both the Gaussian impulse UWB transmitter and Gaussian higher-order impulse UWB transmitter take the low-power and high-speed advantage of digital circuit to generate different waveforms. The measurement results are analyzed and discussed. This thesis also presents a low-power UWB mono-static radar transceiver architecture exploiting the full benefit of UWB bandwidth in radar sensing applications. The transceiver includes a full UWB band transmitter, an UWB receiver front-end, and an on-chip diplexer. The non-coherent UWB transmitter generates pulse modulated baseband signals at different carrier frequencies within the designated 3-10 GHz band using a digitally controlled pulse generator. The test shows the proposed radar transceiver can detect the human respiration pattern within 50 cm distance. The applications of this UWB radar sensing solution in commercialized standard CMOS technology include constant breathing pattern monitoring for gated radiation therapy, realtime monitoring of patients, and any other breathing monitoring. The research paves the way to wireless technology integration with health care and bio-sensor network.
Levels of Some Polyaromatic Hydrocarbons, Heavy Metals and Capacity of Microbes Isolated from Soil Contaminated with Diesel to Utilize Hexadecane

Soil samples contaminated with diesel were analysed to determine the bacterial and fungal diversity together with the concentration of polyaromatic hydrocarbons (PAHs) and some selected metals which are often targets in environmental checks. Bacteria and fungi were isolated and identified using standard microbiological methods. Identification and quantification of PAH, metal was accomplished using standard methods. A total of fifteen fungal species were isolated and identified. Enterobacter xiangfangensis isolated was identified using molecular tools. Degradation test using Rhizopus stolonifer and Enterobacter xiangfangensis separately was done. The fungal growth pattern revealed that there was an increase in viable cell number from 0.05 to 0.25 (80%) at 84ppm of nickel nitrate (highest). The highest bacterial count was 18.0× 10 6 cfu/ml. The results showed that six of the USEPA target PAH assayed were detected. The concentrations of the priority pollutants in the soil samples varied from 2.08 mg/kg to 1.28 mg/kg for site 1 and 1.99 mg/kg to 1.03 mg/kg in site 2. Cd was found below detection limit. These results are valuable in addition to other reports on decontamination of sites co-contaminated. Future efforts will be aimed at determining the extent that microorganisms can utilise both heavy metals and hydrocarbons.
Image Retrieval by using histogram equalization and DBTCF using SVZ

Retrieving images as of from vast quantity of database which is based on to their content are being recognized content based image retrieval. Efficiency of any CBIR system is depend on features mined to stand for an image. As a outcome feature extraction is crucial step in design and the development of some CBIR. Most normally used features to signify images are Color, texture and shape. Here the Block truncation coding feature known as (BTCF) is used so as to compress the image. Further it give thought of Support Vector Machine also known (SVM) classifier. In paper the block of data is also divided into different chunks, so that image of single instance can be stored in these chunks. So replication will be enhanced with the aid of compression techniques which is discussed in detail. Here basic CBIR system is being developed by the combine features like color correlogram , color moments and Gabor wavelet transform all along by way of histogram descriptor. Further outcome is being obtained are then compared through CBIR system is using the SVM classifier.
Influence of an Urban Paved Environment
on Tree Dimensions and Vitality Characteristics:
A Case Study of Sycamore Maple
(Acer pseudoplatanus L.)

In this research, tree sensitivity to the surrounding highly paved environment was analysed at several locations within one urban core (Novi Sad, Serbia). In the future, urban areas will become denser and will, in interaction with intensive climate change, negatively affect the urban forestry performance. Hence, in-depth understanding of the interactions between site-specific parameters, such as pavement and trees, is necessary. When conducting analyses, in this research the data was separated into four groups (0−2; 2−4; 4−6; >6 m) by two grouped parameters that define the interaction between trees and paved surfaces across the streets. The findings revealed that paved surroundings exerted the most significant effect on tree dimensions and lower on vitality. Moreover, tree height, diameter at breast height, crown width and phytopathological and entomological damage emerged as the most reliable indicators of plant stress caused by the negative influences of a paved environment. Reduced uniformity was noted for trees closer to the traffic and in areas with a narrow landscape strip. In general, the distance from the traffic has a stronger influence than the width of landscape strip on the analysed tree characteristics. Furthermore, the sycamore maple and its red leaf cultivar can be recommended for planting in highly paved areas across streets.
