We report the discovery of a narrow-line QSO (NLQSO) RX J1334.2+3759 with a steep soft X-ray spectrum. Soft X-ray emission from the NLQSO is highly variable. Changes in the intensity by a factor of ∼ 2 have been detected in the ROSAT PSPC observations of RX J1334.2+3759 on time scales of∼ 20000−40000 s. Rapid variability events have also been observed from RX J1334.2+3759. The most extreme vari...

Offset pulse position modulation (OPPM) and Dicode (DiPPM) have been introduced as new attractive techniques, however, they are suffering from erasure, wrong slot, false alarm errors. in this paper, two types of error correction (EC) codes, Low-Density Parity Check (LDPC) code Reed Solomon (RS) code, where paired the OPPM DiPPM systems to reduce bugs, analyze best EC parameters, choose superlat...

Abstract The main source of cadmium (Cd) accumulates in humans is through the food chain processes when living things uptake Cd from soils. In this paper, spent mushroom waste (SMW) was used as an approach to reduce contamination growth medium. Thus, different percentages SMW were mixed on Cd-polluted soil (20000 ppm per volume 1000 cm 3 ) medium: T0 (0%), T1 (5%), T2 (10%), T3 (15%), and T4 (2...

Geometric morphometric shape analyses are used to compare the maxillae of the Kenyanthropus platyops holotype KNM-WT 40000, the Australopithecus deyiremeda holotype BRT-VP-3/1 and other australopiths. The main aim is to explore the relationship between these two specimens and contemporary Australopithecus afarensis Five landmarks placed on lateral views of the maxillae quantify key aspects of t...

Process improvements within ITSM are guided by prescriptions of frameworks like ITIL and ISO 20000. Since improvements cause costs, they need to be beneficial to the respective organization. This means to implement ITSM process improvement frameworks according to the specific needs of organizations. In this research in progress a concept is presented that supports this approach by sharing knowl...
