Design of CMOS Architecture for Small Signal Acquisition
Kirubakaran G, Abirami K, Nandhini R
Abstract: This paper describes a method for reducing the power consumption and chip area of small signal acquisition system. In this proposed system, the digital CMOS technology operates with a low supply voltage of 0.5V. Voltage to Time Converter (VTC) block is used for reducing the delay. Digital to Current Converter (DCC) loop is utilized for performing offset cancellation. The Architecture is implemented in a 250nm CMOS technology. A digital feedback loop is employed to cancel the impact of the dc offset in the circuit, which eliminates the need for coupling capacitors.

The activity levels of Lactate dehydrogenase in the seminal plasma of normospermic and infertile men
Karrar Salih Mahdi and FarisN. A. Al-Hady
Abstract: Background: This study involved 122 seminal fluid samples collected from sub-fertile and ten samples of fertile men, once the abstinence period (3 to 5 days). This take a glance at became performed in the laboratory of Babylon Maternity and children and personal laboratories throughout the period from October 2016 to March 2017. Objective: The study aimed to analysis some explanations of male infertility were disorder in most reasons, so this observe aimed to attempt for decide the cause for physiological condition part through valuable of LDH activity in seminal plasma of infertility men and compared it with fertile men. Results: The results revealed the significant differences (P˂0.05) in an average of LDH activity levels between the various groups, the highest level was shown within the groups of fertile and normospermia and the lowest level in the azoospermia, oligospermia and oligo-asthenospermia however asthenospermia and terato-asthenospermia have a similar level of activity. Conclusion: It was concluded the significance of LDH activity to detection the capability of gland secretion and normal semen components.

Polyvinyl alcohol - Poly-Acrylic Acid Bio-Polymeric Blend with Titanium Nitride Nanoparticles Films For Antibacterial Activity against Staphylococcus aureus
Ahmed Hashim and Zinah Sattar Hamad
Abstract: Antibacterial application of (polyvinyl alcohol - poly-acrylic acid) blend and (polyvinyl alcohol - poly-acrylic acid) blend doped by titanium nitride nanoparticles has been investigated. The (PVA-PAA-TiN) nanocomposites were prepared by using casting method. The nanocomposites prepared by weight percentage of polymers: polyvinyl alcohol (85 wt.%) and poly-acrylic acid (15 wt.%). The titanium nitride nanoparticles were added to (PVA-PAA) blend with different concentrations are (1.5, 3, 4.5, and 6) wt.%. The nanocomposites were tested for antibacterial against staphylococcus aureus (S. aureus). The results showed that the (PVA-PAA-TiN) nanocomposites have good activity for antibacterial.
