Abstrak. Proximate analysis dan elemental merupakan dua dari beberapa metode yang umum digunakan untuk uji jaringan tanaman. Namun, tersebut butuh waktu, tenaga, bahan kimia, biaya mahal serta tidak real time. Sehingga para pakar mencari alternatif lain, yaitu menggunakan Spektroskop sinar infra merah dekat (Near Infrared Spectroscopy, NIRS) memprediksi kandungan unsur terkandung dalam tanah ma...

Near-infrared spectroscopy (NIRS) is a novel imaging technique of potential value in the pre-surgical investigation of patients with refractory epilepsy. We recorded simultaneously electrophysiology (EEG; Compumedics, USA) and near-infrared spectroscopy (NIRS; ISS, USA) to examine the localization of the ictal onset zone and assess language lateralization in a young epileptic boy (L.H., 10 year...

Interferometric near-infrared spectroscopy (iNIRS) is a new technique that measures time-of-flight- (TOF-) resolved autocorrelations in turbid media, enabling simultaneous estimation of optical and dynamical properties. Here, we demonstrate reflectance-mode iNIRS for noninvasive monitoring of a mouse brain in vivo. A method for more precise quantification with less static interference from supe...

Organic matter digestibility (OMD), an essential criterion for the evaluation of the nutrition of ruminants, cannot be measured easily at pasture. Therefore, the objective of this study was to test and compare 2 methods of OMD prediction based on the fecal CP content (CPf) or near infrared reflectance spectroscopy (NIRS) applied to feces. First, published equations derived from fecal N (Eq. 1(C...

Near infrared reflectance spectroscopy (NIRS) provides an opportunity to measure cowspecific organic matter digestibility (OMD) from fecal samples. In this study individual digestibility measurements from a trial with 47 cows were investigated. Digestibility increased when lactation progressed. The repeatability estimates between different lactation stages were low which suggests that several f...

Traumatic brain injury (TBI) occurs when a sudden trauma causes damage to the brain. TBI can result head suddenly and violently impacts an object or pierces skull enters tissue. Secondary injuries after traumatic lead impairments on cerebral oxygenation autoregulation. Considering that secondary often take place within first hours trauma, noninvasive monitoring might be helpful in providing ear...

Background. A caries lesion causes changes in the optical properties of the affected tissue. Currently a caries lesion can be detected only at a relatively late stage of development. Caries diagnosis also suffers from high interobserver variance. Methods. This is a pilot study to test the suitability of an optical diffuse reflectance spectroscopy for caries diagnosis. Reflectance visible/near-i...

Cerebral near-infrared spectroscopy (NIRS) has long represented an exciting prospect for the noninvasive monitoring of cerebral tissue oxygenation and perfusion in the context of traumatic brain injury (TBI), although uncertainty still exists regarding the reliability of this technology specifically within this field. We have undertaken a review of the existing literature relating to the applic...
