The study area is an oil and gas field that has a low resistivity reservoir zone in the Talang AkarFormation, South Sumatera Basin. composed of siltstone sandstone was depositedin shallow to transitional marine environment. aim this identify determine potential oflow reservoirs formation. data used include well log, mud core data(porosity, permeability, petrography), formation water analysis, b...

The fate of phosphate added to fishponds and the inorganic processes of phosphorus fixation were studied in Israel. Conditions in these ponds are different from those of the more humid climatic zones in having alkaline water and high calcium content. In these condi tions most of the phosphorus added is precipitated as Ca3(P04)2. rctical aspects of this are discussed. The quantitative theobottom...

In this paper, the decision-level data fusion techniques are extended to the multiuser detection (MUD) field. Then two novel MUD algorithms, that is the chairman arbitrating decision-level fusion criterion (CA-DFC) based MUD algorithm and the veto logic decision-level fusion criterion (VL-DFC) based MUD algorithm, are proposed for DS-UWB communication systems. In CA-DFC based method, the chairm...

Submarine mud volcanoes are a significant source of methane to the atmosphere. The Napoli mud volcano, situated in the brine-impacted Olimpi Area of the Eastern Mediterranean Sea, emits mainly biogenic methane particularly at the centre of the mud volcano. Temperature gradients support the suggestion that Napoli is a cold mud volcano with moderate fluid flow rates. Biogeochemical and molecular ...

Recently, the transmission of vector quantization (VQ) over a code-division multiple access (CDMA) channel has received a considerable attention in research community. The complexity of the optimal decoding for VQ in CDMA communications is prohibitive for implementation, especially for systems with a medium or large number of users. A suboptimal approach to VQ decoding over a CDMA channel, dist...

Drill-bit seismic data can provide valuable information about reflector characteristics and prediction ahead of the drill bit. In this paper, I apply the interferometric migration method, which both includes crosscorrelogram and autocorrelogram migration, to Union Pacific Resources Corporation (UPRC) drill-bit data. Here, the data are recorded on the earth’s free surface while a tri-cone drill-...

Management intervention to avoid inbreeding in captive breeding programs is essential to maintain maximum genetic diversity. Vasectomy was enlisted in drill monkeys (Mandrillus leucophaeus) to achieve this purpose without altering the social dynamics of the groups. All the vasectomies were carried out at the Drill Rehabilitation and Breeding Centre, Cross River State, Nigeria. Vasectomy in dril...

no tillage systems can reduce operating costs, enhance soil organic matter, ameliorate soil structure and prevent environmental damage caused by stubble burning. however, the lack of an appropriate direct drill for the hardened soil of arid areas reduces adequate soil-seed contact and, thus, the system has shown contradictory results in past tests. developing a direct drill to place the seed an...

Older patients are increasingly undergoing allogeneic hematopoietic transplantation. A relevant question is whether outcomes can be improved with a younger allele-level 8/8 HLA-matched unrelated donor (MUD) rather than an older HLA-matched sibling (MSD). Accordingly, transplants in leukemia/lymphoma patients age ≥50 years were analyzed comparing outcomes for recipients of MSD ≥50 (n = 1415) ver...

House mice (Mus musculus) emit complex ultrasonic vocalizations (USVs) during social and sexual interactions, which have features similar to bird song (i.e., they are composed of several different types of syllables, uttered in succession over time to form a pattern of sequences). Manually processing complex vocalization data is time-consuming and potentially subjective, and therefore, we devel...
