An integral domain $D$ is called a emph{locally GCD domain} if $D_{M}$ is aGCD domain for every maximal ideal $M$ of $D$. We study somering-theoretic properties of locally GCD domains. E.g., we show that $%D$ is a locally GCD domain if and only if $aDcap bD$ is locally principalfor all $0neq a,bin D$, and flat overrings of a locally GCD domain arelocally GCD. We also show that the t-class group...

abstract time domain reflectometry (tdr) is a widely used method for measuring the dielectric constant (ka) and bulk electrical conductivity (σa) in soils. the tdr-measured σa and ka can be used to calculate the soil solution electrical conductivity, (σp). a theoretical model describing a linear relationship between bulk electrical conductivity, σa, and dielectric constant, ka, in moist soil wa...

To develop a high-performance additive that can meet different operating conditions, three liquid crystals (LCs) were developed as additives for base oil. The structures and thermal stabilities of the obtained LCs characterized by nuclear magnetic resonance (NMR), Fourier transform infrared (FT-IR) spectroscopy, mass spectroscopy (MS), thermogravimetric analysis (TGA). effects mesogenic-phase t...

Domain adaptation is a powerful technique given a wide amount of labeled data from similar attributes in different domains. In real-world applications, there is a huge number of data but almost more of them are unlabeled. It is effective in image classification where it is expensive and time-consuming to obtain adequate label data. We propose a novel method named DALRRL, which consists of deep ...

this paper uses the tsuji’s characteristic to investigate the uniqueness of transcen- dental meromorphic function with shared values in an angular domain dealing with the multiple values which improve a result of j. zheng.

The employability of seafarers is directly linked to their competency level. Perhaps, this is the main reason why crew members from certain countries enjoy preference in the employment market. Therefore, the sea career prospects of Malaysian seafarers should be viewed from their competency which strongly related to the kind of training offered by Marine Education Training (MET) institutions. In...

The objectives of this study were to determine if environmental acidity reduces swimming performance in the acid-tolerant yellow perch (Perca flavescens) and to use swimming performance as an indicator of fitness in testing whether fish from naturally acidic environments perform better in acidic water. Perch from a naturally acidic lake (pH4-4) or a nearby circumneutral lake were swum after eit...

University Course Timetabling (UCT) problem is a combinatorial optimization in which set of events has to be scheduled timeslots and located suitable room by considering all the constraint involved. A feasible timetable plays an important role ensuring tasks or are carried out appropriately. However, producing one not easy task due its large data size variety requirements In this research, math...

Let $D$ be an integral domain and $star$ a semistar operation stable and of finite type on it. We define the semistar dimension (inequality) formula and discover their relations with $star$-universally catenarian domains and $star$-stably strong S-domains. As an application, we give new characterizations of $star$-quasi-Pr"{u}fer domains and UM$t$ domains in terms of dimension inequal...
