There are conflicting and even contradictory claims as to when exactly double entry bookkeeping arrived to New Spain as well as its diffusion during the colonial era. Although we fail to present evidence from Mexican private enterprise, we address the…

Dieback of mamey sapote (Pouteria sapota) grafts is the most important disease during vegetative propagation in commercial nurseries. In 2008, Lasiodiplodia theobromae identified by cultural, morphological and molecular characterization was associated with this disease in 97 % of necrotic rootstocks…

The efficient identification of hardware and software faults in parallel and distributed systems still remains a challenge in today's most prolific decentralized environments. System-level fault diagnosis is concerned with the detection of all faulty nodes in a set of hundreds…

Today control is required in any field or application. Nowadays, classic control is the most used, but it is well-known that users need to know the system's characteristics to reach optimal control. This paper is focused on designing a proportional…

Research on learning processes has shown that students tend to learn in different ways and prefer to use different teaching resources. The understanding of learning styles can be used to identify, and implement, better teaching and learning strategies, in order…

Chili pepper (Capsicum spp.) is an important horticultural crop worldwide. Chili pepper fruits from different Capsicum species have been highly consumed in Rexico since pre-Columbian times. Some Capsicum species synthesize and accumulate anthocyanins in different tissues and organs. Although the…

A parametric method to carry out fringe pattern demodulation by means of a particle swarm optimization is presented. The phase is approximated by the parametric estimation of an «th-grade polynomial so that no further unwrapping is required. A particle swarm…

A case-control study assessed factors associated with HIV infection among cases (59 persons aged 50 years or older at HIV diagnosis) and controls (59 self-reported uninfected persons aged 50 years and older) from Southern Brazil. Participants answered a 142-item questionnaire…

Service-oriented software engineering (SoSE) is a new paradigm for building software systems, fostered by the availability of a new -but already mature- computing technology based on services. SoSE advances the current object-oriented and the component-based software engineering paradigms. Under that…
