OBJECTIVE This study aimed to assess the efficiency of six protocols for cleaning-up tooth enamel after bracket debonding. METHODS A total of 60 premolars were divided into six groups, according to the tools used for clean-up: 12-blade bur at low speed (G12L), 12-blade bur at high speed (G12H), 30-blade bur at low speed (G30L), DU10CO ORTHO polisher (GDU), Renew System (GR) and Diagloss polis...

The research work has evaluated the performance of the proposed link in terms of QFactor and BER at wavelength of 1550 nm and 1350 nm at transmission distance of 30 km. The comparison has also been drawn among the proposed EPON link with NRZ and RZ modulation scheme. In this work, simulative investigation to evaluate the performance of EPON transmission links using NRZ and RZ modulation schemes...

BACKGROUND To determine the rates of hepatotoxicity and treatment completion associated with intermittent rifampin and pyrazinamide (RZ) therapy for latent tuberculosis infection, we evaluated a cohort of patients from a targeted tuberculin testing site in Tennessee. METHODS From 4 February 2000 through 9 November 2001, a total of 423 patients with latent tuberculosis infection received direc...

In this paper we communicate the use of advanced modulation format CS-RZ substituting conventional NRZ format. The use of CS-RZ over NRZ proves to give better quality in terms of Q factor, Received Power and Bit Error Rate. The communication also investigates the system for Ring circumference which comes out to be of double values using CS-RZ. This increment leads to fulfillment of capacity cri...

Realizability theory is not just a fundamental tool in logic and computability. It also has direct application to the design and implementation of programs, since it can produce code interfaces for the data structure corresponding to a mathematical theory. Our tool, called RZ, serves as a bridge between the worlds of constructive mathematics and programming. By using the realizability interpret...

Suppose (X ,Y ) is a pair of sequence of independent and identically distributed samples from a binary symmetric source. Using linear random codes, Korner and Morton [1] showed that the modulotwo sum sequence Z = X ⊕Y can be described to a common decoder at rates Rx, Ry , and Rz bits iff Rx + Rz > H(Z) and Ry + Rz > H(Z) where H(Z) is the entropy of the random variable Z . Here we provide an al...

We report a measured gross coding gain of 6.8dB for 21.42Gb/s RZ-DQPSK using standard FEC in combination with differential precoding. Furthermore we show that RZ-DQPSK has approximately a 2dB higher FEC coding gain than RZ-DPSK. Introduction Recently the return to zero optical differential quadrature phase shift keying (RZ-DQPSK) modulation format attracted attention because of its advantageous...

Temperate crops cannot grow well in the tropics without rootzone cooling. As cooling increased production costs, this experiment aimed to study the growth of various Lactuca genotypes and propose possible ways of reducing these costs, without compromising productivity. A recombinant inbred line (RIL) of lettuce and its parental lines (L. serriola and L. sativa "Salinas") were grown aeroponicall...

BACKGROUND Severe liver injuries were attributed to the rifampin and pyrazinamide (RZ) regimen after it was recommended for treating latent tuberculosis infection. Implicating RZ as the likeliest cause required excluding alternative causes. METHODS US health departments reported data on patients who died or were hospitalized for liver disease within 1 month after taking RZ for latent tubercul...
