SENSOR TIMBAL BERBASIS POTENSIOMETRI UNTUK MENDETEKSI KADAR TIMBAL DALAM DARAH

Jurnal Penelitian Saintek, 2017
Keberadaan timbal di lingkungan yang disebabkan oleh polusi dapat masuk dalam darah. Menurut Center for Disease Control and Prevention (CDC) batas ambang timbal dalam darah yaitu 4.8×10-7 M. Apabila melebihi batas tersebut maka dapat menyebabkan keracunan bahkan kematian.

Effects of a Rhythmic Drumming and Movement Intervention on Reaction Time in Community-Dwelling Older Adults: A Nonrandomized Pilot Study. [PDF]

J Aging Res
Driving is often the preferred mode of mobility for older adults in the United States, yet age‐related functional declines increasingly compromise driver safety. Driver reaction time is one of the most critical factors related to accident avoidance and is particularly vulnerable to age‐related decline.

Drought and Warming-Induced Drying Suppress Soil Respiration but Amplify Rewetting-Induced Pulses in a Temperate Pasture. [PDF]

Glob Chang Biol
A factorial rainfall × warming field experiment showed that drought and warming suppressed overall soil respiration but amplified rewetting‐induced CO2 pulses via contrasting effects of moisture, temperature, and substrate availability. Their interaction shifted seasonally, from additive (spring) to antagonistic (summer‐autumn) and synergistic (winter),

Using Landsat Satellite Imagery to Investigate Spatial and Temporal Variation in Life History Traits in a Long-Term Study Population of Superb Fairy-Wrens <i>Malurus cyaneus</i>. [PDF]

Ecol Evol
We used 27 years of data from an insectivorous passerine in southeastern Australia, the superb fairy‐wren Malurus cyaneus, to assess how climate variation influences vegetation productivity and, indirectly, reproduction and survival via potential trophic interactions.

Response of native (Quercus robur L.) and alien (Quercus rubra L.) species to water stress and nutrient input in European temperate ecosystems. [PDF]

Physiol Plant
Abstract Drought and nutrient‐poor soils can increase the invasive potential of non‐native species, further changing the ecosystems they invade. The high adaptability of these alien species, especially in their efficient use of resources, improves their resilience against abiotic stress.
