Gelombang elektromagnetik Extremely Low Frequency merupakan salah satu jenis dari radiasi non ionizing karena gelombang ELF memiliki nilai frekuensi lebih kecil 300 Hz. Penelitian ini bertujuan untuk mengkaji pengaruh paparan medan magnet terhadap pH dan ketahanan fisik jamur tiram ( Pleurotus ostreatus ). Jenis penelitian eksperimen menggunakan desain rancangan acak lengkap (RAL). Jamur putih ...
The use of smart phones is increasing in the world. This excessive use, especially in the last two decades, has created too much concern on the effects of emitted electromagnetic fields and specific absorption rate on human health. In this descriptive-analytical study of the electric field resulting from smart phones of Samsung and Nokia by portable measuring device, electromagnetic field, Mode...
sno nanoparticles were synthesized using microwave–assisted hydrothermal method. it was noticed that at 300 and 600 watt microwave power, sno formed and remained in the tetragonal phase. at 900 watt, sno2 started appearing and a mixture of sno and sno2 phases coexisted. the particle size varied from ~2 to ~13 nm at 300 to 900 watt radiation power. the uv-v absorption spectra showed the excitoni...
PURPOSE To determine parameters for the efficacy of transscleral cyclophotocoagulation (TSCPC) using a diode laser. METHODS We performed TSCPC on 74 pigmented rabbits with different exposure powers and varying number of applications, followed by clinical observation and histological examination up to 24 weeks. RESULTS Based on observation of the clinical course, the most favorable parameter...
We report an event-related potential (ERP) experiment of human recognition memory that explored the relation between conscious awareness and electrophysiological activity of the brain. We recorded ERPs from healthy adults while they made "remember" and "know" recognition judgments about previously seen words. These two kinds of judgments reflect "autonoetic" and "noetic" awareness, respectively...
Rice whitening is an important stage in rice milling process and improvement of the whitener machines has a remarkable effect on rice loss. To decrease the amounts of broken rice and losses, the rotor of the blade whitener was equipped with screw conveyor. To investigate the effects of rotor speed (in four levels: 600, 700, 800 and 900 rpm) and output rate (in three levels: 400, 500 and 600 kg/...
In Ref. [1] the BESIII collaboration published a cross section measurement of process e+e−→π+π− in energy range between 600 and 900 MeV. this corrigendum, we report corrected evaluation statistical errors terms fully propagated covariance matrix. The correction also yields reduced uncertainty for hadronic vacuum polarization contribution to anomalous magnetic moment muon, which now reads as aμπ...
We are studying non-thermal effects of continuous wave (2 W/kg) and GSM-modulated (2 or 4 W/kg) 900 MHz radiofrequency (RF) electromagnetic field exposure on synaptic transmission and plasticity in rat perirhinal cortex slices. Preliminary results, still under elaboration, indicate that the exposure to both RF signals may cause small changes in synaptic plasticity in our experimental conditions.
