The intercalation the of 4,4'-oxybis(benzoic acid) anion (OBA(2-)) into MgAl-layered double hydroxide (LDH) was carried out in formamide, and the structural change of the nanocomposites from homogenous to staging was investigated through in situ XRD, FT-IR, TG-DSC, SEM and molecular dynamics (MD) simulations. In both formamide and water, the nanocomposites had a homogenous structure with a basa...

با توجه به اهمیت حذف یون استرانسیم موجود در پساب‌­های هسته­ای، کار حاضر ضمن سنتز لیگاندهای هیدروکسی بنزآلدهید پروپیل تری اتوکسی سیلان (Si-HL3(EtO)) و پیریدیل متیلیدین (Si-L3(EtO)) بررسی خصوصیات نانو ذرات سیلیکای اصلاح ­شده این لیگاندها ­عنوان جاذب جامد از محلول آبی پرداخته شد پارامترهایی مانند pH، زمان، جرم جاذب، دما یون‌­های مزاحم مورد آزمایش قرار گرفت. رفتار جذبی جاذ­ب‌­ها نشان داد سطح توانای...

What convinces users to share information about themselves in an ad-based online world? We explore users’ willingness to share data in the context of online behavioural advertising (OBA) and tracking prevention tools. We find positive responses for OBA and clear preferences for which types of information users would like to disclose. Factors including privacy attitudes and control mechanisms im...

BACKGROUND Innovative financing strategies such as those that integrate supply and demand elements like the output-based approach (OBA) have been implemented to reduce financial barriers to maternal health services. The Kenyan government with support from the German Development Bank (KfW) implemented an OBA voucher program to subsidize priority reproductive health services. Little evidence exis...

The semantic web depends on the use of ontologies to let electronic systems interpret contextual information. Optimally, the handling and access of ontologies should be completely transparent to the user. As a means to this end, we have developed a service that attempts to bridge the gap between experts in a certain knowledge domain, ontologists, and application developers. The ontology-based a...

We present results of a 45-participant laboratory study investigating the usability of tools to limit online behavioral advertising (OBA). We tested nine tools, including tools that block access to advertising websites, tools that set cookies indicating a user’s preference to opt out of OBA, and privacy tools that are built directly into web browsers. We interviewed participants about OBA, obse...

We present two proactive resource allocation algorithms, RBA -FT and OBA-FT, for fault-tolerant asynchronous real-time distributed systems. The algorithms consider an application model where task timeliness is specified by Jensen’s benefit functions and the anticipated application workload during future time intervals is described by adaptation functions. In addition, we assume that reliability...

Dry matter intake (DMI) is related to dietary NDF content (Mertens, 1987) and in vitro NDF digestibility (NDFD, % of NDF; Oba and Allen, 1999). The NRC (2001) summative energy equation is based on fiber digestibility calculated using lignin. Whole-plant lignin content was found to have a strong negative relationship with in-vitro NDFD within comparisons of brown midrib (bm3) hybrids to isogenic...

A low-power parallel multiplier based on optimized bypassing architecture (OBA) is proposed. The proposed OBA has two kinds of adder cells to reduce power consumption by 15.7 %. One is the two-dimensional bypassing adder (TDBA) which performs both row and column bypassing scheme simultaneously, and the other is the modified row-bypassing adder (MRBA) for the proposed row-bypassing scheme. In th...

Functional overreaching has been linked to alterations in immunity and host pathogen defense, but little is known as to whether or not running and cycling evoke different responses. This study compared inflammation, muscle damage and soreness, and innate immune function responses to a 3-day period of intensified exercise in trained long distance runners (N=13, age 34.4±2.4year) and cyclists (N=...
