A new, simple, and rapid one-step integrated method for the biotechnology treatment of raw olive oil mill waste (OMW) is discussed. The innovations introduced involve primarily application microaerobic composting processes OMW bioremediation plus addition both a zeolite tailor-made biocatalyst extremely rich in soil microorganisms. latter operates at wide pH range provides, apart from microorga...

Air conditioning has become an expected feature in new California homes, even those in cooler coastal locations. Because many Californians run their air conditioners for just a few days out of the year, air conditioners use only 10%–12% of the energy in homes, yet they are responsible for about 43% of the residential peak load. This load from hell has been the bane of California utilities, and ...

This work aims to verify the possibility of valuing coconut husk fiber through pyrolysis for production carbonized, and evaluate influence conditions in its potential use as a soil conditioner. Biomass were pyrolyzed used peak temperatures 350, 450 550 °C, with immersion time 30 minutes. The characterization included analyses bulk density, proximate analyses, X-RF, total carbon, pH, electrical ...

Biochar has important biogeochemical functions in soil—first as a means to sequester carbon, and second soil conditioner potentially enhance quality fertility. Volatile matter (VM) content is property of biochar that describes its degree thermal alteration, which can have direct influence on carbon nitrogen dynamics soil. In this study, we characterized the VM biochars derived from two locally ...

The aim of the present study was to compare heart rate variability (HRV) at rest and during exercise using a temporal series obtained with the Polar S810i monitor and a signal from a LYNX(R) signal conditioner (BIO EMG 1000 model) with a channel configured for the acquisition of ECG signals. Fifteen healthy subjects aged 20.9 +/- 1.4 years were analyzed. The subjects remained at rest for 20 min...

background: esthetic demands among patients have led to the introduction of tooth-colored restorations. composite resins bond to enamel applying acid etch technique. total etch adhesion systems are still considered as golden standard among bonding systems. however, clinicians have tendency towards using adhesive systems with a simplified application procedure. the aim of the present study is to...
