Incidence of diabetes particularly Non-insulin dependent mellitus is on the rise amongst entire world population in residents belonging to younger age groups developing countries located Southeast Asia. The causes are many and predominated by nature-nurture role. Improper dietary intake w-6 w-3 fatty acids chasing cholesterol myth 70's may be an important reason increased India. Coronary risk Indians associated with prevalence Type 2 mellitus, plasma or tissue levels triglycerides...
Stormwater catch basins are the primary source of mosquitoes targeted by North Shore Mosquito Abatement District, in northern suburbs Chicago. Over a 17-wk period (June to September 2011), 3 clusters located within 0.7-km2 area were monitored weekly with dipper samples immature mosquitoes. During 2nd week monitoring, Natular™ XRT tablets (6.25% spinosad) applied northernmost cluster and FourStar™ Briquets (6% Bacillus sphaericus, 1% thuringiensis israelensis) southernmost cluster; remaining...
Non-insulin-dependent or type 2 diabetes mellitus is on the rise in India particularly affluent urban and rural population. The exact cause unknown. Malnutrition, defective intake of essential fatty acids reduced fibres are found Indian diet, diet dietary factors may be one causes leading to increased incidence disease. Dietary fibers reduce blood glucose cholesterol levels. Resistant starches behave as fiber. As rice staple food villages, increase fibre consumption, a special variety...
The design of a circular-waveguide coupled two-layer dielectric resonator antenna (DRA) configuration is presented. It observed that besides reduction in the number layers compared to rectangular waveguide multilayer-DRA structure achieve coupling and enhanced bandwidth, current significantly enhances functionality realization dual band right-hand/left-hand circularly polarized (RHCP/LHCP) configurations without use additional or matching elements, which, best our knowledge, has not been...
Empirical relations for the capacitive and inductive coupling coefficients have been used to compute normal-mode parameters of non-identical microstrip coupled lines. The computed values mode velocities impedances are compared with available results from literature experimental on nonidentical couplers test applicability empirical relations.
Empirical relations for inductive and capacitive coupling coefficients are proposed. The functional relationships based on the physical mechanism of in microstrip lines. Values computed from even- odd-mode impedances phase velocities, available literature, compared with those proposed relations. Microstrip couplers have been designed basis to meet desired isolation.
The Dread Disease:Cancer in the Developing World Kayhan Parsi (bio), Dhrubajyoti Bhattacharya and Justin List (bio) triumvirate of HIV/AIDS, tuberculosis, malaria have dominated our public health focus developing world. Having claimed millions lives, these infectious diseases prompted a large-scale response. Concomitant with efforts has been burgeoning bioethics literature examining global distributive justice. A scholarly waste-land only decade ago, there is now growing rich that aims to...
Diabetes is spreading at an exponential rate in Indian sub-continent. Existing infrastructure of health India poor, particularly its rural sectors. Of all verities diabetes, Type 2 diabetes commoner and about 80%. Different drugs, herbal medicines neutraceuticals are used to control diabetes. Melatonin, the hormone pineal gland being considered as a neutraceutical by FDA. Many workers thought melatonin might have role through central mechanisms. The studies lead many controversies...
A simplified formula for the characteristic impedance of a coplanar waveguide (CPW) has been proposed. The formulation is based on determination static capacitances between parallel strips and found to be valid even up zero gap width.
The preparation of a thick-film ferrimagnetic paste using lithium ferrite powders and its physical, electrical, magnetic properties are described. A resonance technique for the measurement dielectric constant, saturation magnetization, loss tangents, linewidth films at microwave frequencies is presented.

ABSTRACT An investigation of radiated power enhancement infinitesimal quadrupole source using metamaterial shell is presented. It has been demonstrated that a double negative surrounding the can cancel both self and mutual reactance within elements. Moreover, uniform gain characteristic be achieved over wide range thickness. The effects loss, present in shell, are also taken into account for this investigation. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2620–2624,
In this paper, a 1-bit coding reflective metasurface is proposed. It can steer the dual-polarized incident electromagnetic waves towards desired directions along both xz- and yz- cardinal planes. The unit cell of consists slotted cross-dipole on top layer. has ground plane sandwiched in-between two RT5870 dielectric layers. Two positive-intrinsic-negative (PIN) switches are attached layer in x- y- to manipulate TM TE polarized incidences, respectively. With switching between ON OFF states...
The structural characteristics of ZrO2 films along with the interfacial layers deposited on partially strain compensated Si0.69Ge0.3C0.01/Si heterostructure have been investigated using x-ray diffraction (XRD), high resolution transmission electron microscopy (TEM), time-of-flight secondary ion mass spectroscopy (SIMS), and photoelectron (XPS) measurements. XRD spectra show to be polycrystalline both monoclinic tetragonal phases. film physical thickness ∼8.5 nm an amorphous layer a ∼3.6...
The design of a miniaturized CPW-fed rectangular slot antenna over reactive impedance substrate is proposed. Two-dimensional printed periodic circular metallic patches have been introduced on one side the for designing (RIS). Instead conventional metal plate, arrays are as backed material lower substrate. proposed gives 44.77% miniaturization with an improvement bandwidth. exhibits moderate gain acceptable radiation pattern and reasonable efficiency.
