Understanding the link between benefits from protected areas and their relationship with surrounding communities: an exploration in Costa Rica
Protected areas are an essential strategy in preserving natural resources. A central aspect of protected area management is to maintain and improve their relationship with surrounding communities given that local conflicts ...
Does elevation influence the distributional patterns of tropical myxomycetes? A case study in Costa Rica
In order to test the hypothesis that elevation may be an important factor accounting for the distribution of myxomycetes in tropical forests, this project was designed and conducted in Costa Rica. Two lower elevational ...
Desarrollo verde e inclusivo en respuesta al cambio climático
Considerando que Costa Rica estará sumamente expuesta a la amenaza de un clima cambiante, la respuesta al cambio climático no puede esperar. Ya la mayor variabilidad climática y el fenómeno El Niño-Oscilación del Sur ...
Effect of Densification Conditions on Physical Properties of Pellets Made From Sawmill Residues
Sawmill residues produced in wood processing of Pilon (Hyeronimaalchorneoides) and Eucalyptus (Eucalyptus spp) species, were used to fabricate pellets with experimental design equipment. Different manufacturing conditions ...
Using the oxyhydrogen as an additive to increase the performance of an internal combustion engine
Reducing the pollution emission associated with oil combustion is gaining an increasing interest worldwide. Recently, Brown’s gas (HHO gas) has been introduced as an alternative clean source of energy. A system to generate ...
Strategies For The Recovery Of Threatened Natural Systems And Their Role In The Mitigation Of Rapid Urban Growth In Montes De Oca, Costa Rica
Costa Rica is well known for its ecological and landscape diversity. Nevertheless, most of its cities have lost their natural richness due to uncontrolled growth in infrastructure. Urban development has caused surface ...

El texto explora el contexto que, durante los últimos treinta y siete años, ha posibilitado la emergencia de la ciudad neoliberal en Costa Rica. Para ello, se realizan tres apuntes que muestran: i) los ...
Improved PID controller tuning rules for performance degradation/robustness increase trade-off
Definitely, robustness is an important feature that any control system must take into account, especially considering that the design is usually based on low-order linear models that represent the whole controlled process. ...
Model reference pi controller tuning for second order inverse response and dead time processesand science
In this paper, a One-Degree-of-Freedom PI controller is optimized using the model reference tuning approach for a Second Order Inverse Response and Dead Time Process operating as a servo control. In addition, a graphic ...
