The minimal-length paradigm, a possible implication of quantum gravity at low energies, is commonly understood as phenomenological modification Heisenberg's uncertainty relation. We show that this equivalent to cut-off in the space conjugate position representation, i.e. wave numbers, which does not necessarily correspond momentum space. This result generalized several dimensions and noncommuta...
background unlike developed countries, data from the developing world regarding motor developmental disorders is scarce. objectives in the present study, we used the infant neurological international battery (infanib) test to determine the prevalence of motor impairment in 4-18 month-old infants in alborz province, iran, in 2010. patients and methods this study was a descriptive-analytic study ...
Abstract In order to cut off the connection between mobile terminal and communication base stations or Wi-Fi, it is necessary improve electromagnetic shielding efficiency of phone cabinet. This paper analyzes resonant characteristics cabinets. The test method has been introduced. Through Maxwell wave equation boundary conditions, cavity frequency every small drawer on cabinet derived, rectangul...
OBJECTIVE To reduce the number of unnecessary biopsies in patients with benign prostatic disease, however, without missing significant PCa the present study re-evaluates the age-dependent PSA cut-offs in the Tyrol Prostate Cancer (PCa) early detection program. PATIENTS AND METHODS The study population included 2225 patients who underwent prostate biopsy due to elevated PSA levels at our depar...
Background and Aims : One of the factors that lead to failure treatment and return substance abuse is ignoring mental disorders before and after drug withdrawal. Therefore, the aim of the present study was effectiveness of cognitive-behavioral group therapy on anxiety in addicts with successful cut off. Materials and Methods: This study was quasi-experimental. The study design was a pretes...
The present study was conducted in order to investigate the effect of salicylic acid on growth, yield and macro-elements absorption of fennel in split-plot as base on randomized complete block design (RCBD) with three replications in Tehran, Iran. Irrigation regime as main plot was undergone in 5 levels that included: I1: full irrigation, I2: cut off irrigation at stem elo...
BACKGROUND Pneumocystis pneumonia (PCP) is a serious risk for HIV-positive patients. Asymptomatic infection or colonisation with P. jirovecii has been shown to occur frequently. PCR assays frequently identify such cases, due to their high sensitivity. Quantitative real-time PCR (qPCR) gene copy number cut-off values have been suggested to differentiate colonisation and infection; these need to ...
Regional lymph node (LN) metastasis has a significant impact for prediction of recurrence in patients with papillary thyroid cancers (PTC); however, the prognostic value of the lymph node ratio (LNR), which is defined as the ratio of the number of metastatic LNs to the total number of investigated LNs, is controversial. In this study, we determined the optimal cut-off values of LNRs for the pre...
