Data for this study were obtained with the aid of structured questionnaire. A total of 70 questionnaires were administered to the palm oil farmers/ producers with the response rate of 95.71 %. The data were analysed by the use of descriptive statistics, multiple regression and costs and returns tools. The results obtained revealed that although mechanized palm oil processors were not fully econ...

Mechanized nanoparticles (MNPs) consisting of supramolecular machines attached to the surface of mesoporous silica nanoparticles are designed to release encapsulated guest molecules controllably under pH activation. The molecular machines are comprised of cucurbit[6]uril (CB[6]) rings that encircle tethered trisammonium stalks and can be tuned to respond under specific pH conditions through che...

We face the problem of obtaining a certified version of a crucial algorithm in the field of Homological Algebra, known as “Perturbation Lemma”. This lemma is intensively used in the software system “Kenzo”, devoted to symbolic computation in Homological Algebra. To this end, we use the proof assistant “Isabelle”. Our main motivations are to increase the knowledge in the algorithmic nature of th...

Forests in lowland Bolivia suffer from severe deforestation caused by different types of agents and land use activities. We identify three major proximate causes of deforestation. The largest share of deforestation is attributable to the expansion of mechanized agriculture, followed by cattle ranching and small-scale agriculture. We utilize a spatially explicit multinomial logit model to analyz...

The formal verification of compilers and related programming tools depends crucially on the availability of appropriate mechanized semantics for the source, intermediate and target languages. In this invited talk, I review various forms of operational semantics and their mechanization, based on my experience with the formal verification of the CompCert C compiler. What does this program do, exa...

The considerations are discussed that make continuous monitoring of reaction-progress curves superior to fixed-incubation methods in the determination of enzyme activity. Provided that they are used with caution and their limitations are appreciated, fixedincubation methods continue to fulfill a useful, though diminishing, role in clinical enzymology because of their adaptability to existing pa...

The Ontological Argument, an 11th Century proof of the existence of God, is a good candidate for Fun With Formal Methods as nearly everyone finds the topic interesting. We formalize the Argument in PVS and verify its correctness. The formalization raises delicate questions in formal logic and provides an opportunity to show how these are handled, soundly and efficiently, by the predicatively-su...
