Aberrant Thyroid in the Parapharyngeal Space

Introduction Aberrant thyroid is a mass of tissue having the structure of a normal or pathological thyroid gland and situated at some definite distance from normal thyroid, with which it has no connection. The prevalance of ectopic thyroid is 1 case per 100,000- 300,000 persons1 and the incidence of aberrant thyroid in parapharyngeal space is even rarer. Materials and Methods A rare case of aberrant thyroid in parapharyngeal space is reported, which presented as oropharyngeal mass and dysphagia. She also had   thyroid gland in the usual position. Result She was managed surgically with transcervical approach and was euthyroid postoperatively. Conclusion Aberrant thyroid should be one of the differential diagnoses for parapharyngeal space masses

Thin Domain Walls in Lyra Geometry

This paper studies thin domain walls within the frame work of Lyra Geometry. We have considered two models. First one is the thin domain wall with negligible pressures perpendicular and transverse direction to the wall and secondly, we take a particular type of thin domain wall where the pressure in the perpendicular direction is negligible but transverse pressures are existed. It is shown that the thin domain walls have no particle horizon and the gravitational force due to them is attractive.Comment: 8 pages, typos are corrected, published Astrophysics and Space Sciences 305, 337 (2006

Molecular mapping of dry root rot resistance genes in chickpea (Cicer arietinum L.)

Dry root rot (DRR) caused by Rhizoctonia bataticola [(Taub.) Butler] is an emerging disease of chickpea (Cicer arietinum L.) and a serious constraint to chickpea production in warm and arid regions. To identify the genomic regions conferring resistance to DRR, a total of 182 F9 derived Recombinant Inbred Lines (RILs) were developed from the cross between a susceptible line BG 212 and moderately resistant breeding line ICCV 08305. The parental lines and RILs were screened against Rb 6 isolate of R. bataticola using paper towel method under controlled environment at ICRISAT during 2016 and 2017. The RILs were genotyped with cost-effective SNP genotyping platform, Affymetrix Axiom CicerSNP array. As a result, a high-density genetic map with 13,110 SNP markers spanning 1224.11 cM with an average inter marker distance of 0.09 cM was developed. A single minor QTL (‘qDRR-8’) explaining 6.70% PVE with LOD scores 3.34 was identified on CaLG08 for DRR resistance which could be further explored for mining candidate genes and the linked SNP markers could be further validated for application in marker-assisted selection of DRR resistance in chickpea breeding programs

Interference between verbal concept formation and spatial mental rotation in female subjects

In this study the relation between spatial cognition and verbal intelligence abilities was examined in case of 52 women. Interference between mental rotation performance and verbal intelligence scores was found. Women with good verbal abilities have lower scores in mental rotation tasks than subjects with poorer verbal abilities. This finding is in accordance with some basic models of a dual-coding system. The spatial functions represented in mental rotation interfered with verbal-based concept formation and lexical knowledge in college women

An inductive down converter system-in-package for integrated power management in battery-powered applications

With the increasing number of voltage conversions that have to be efficiently implemented in a mobile device, the PCB space occupied by switched-mode DC-DC converters with external passive components will become unacceptably high. Therefore, a clear need exists for small-form-factor high-efficiency DC-DC converters having the necessary passive components integrated within one package. This will enable the integration of a DC-DC converter with the load and consequently the system integration of power management. This paper describes the measurement results of an integrated inductive down converter, where the active electronics (power stage and driver circuitry) has been implemented in 0.18-mum CMOS technology and the passive components (output LC filter and decoupling capacitor) have been implemented in a state- of-the-art proprietary passive-integration process technology using high-density trench-MOS capacitors (80 nF/mm2 ) and an 8-mum thick copper top metallization layer. The active die of the converter has been flip-chipped on top of the passive die to reduce parasitic component values. This yields a System-in-Package (SiP) that achieves a step-down DC-DC conversion without any external components. Due to the limited inductance achievable with the used planar air coil in the acceptable area, the switching frequency of the DC-DC converter has been increased. At the same time, Zero-Voltage-Switching (ZVS) measures have been implemented to reduce the switching losses at this increased frequency. A maximum efficiency of 65% at 80 MHz has been achieved for an input voltage of 1.8 V, an output voltage of 1.1 V and an output current of 100 mA. After explaining the motivation behind integrated power management and the choice for an integrated inductive converter, this paper describes the main design aspects of the realized integrated inductive DC-DC down converter. Next, it presents some details of the used passive-integration process, the design of the passi- - ve die including the LC filter and the construction of the SiP. Finally, the measurement results of the converter are discussed and conclusions are drawn
