Strategies for nanoencapsulation of algal proteins, protein hydrolysates and bioactive peptides: the effect of encapsulation techniques on bioactive properties
(Springer Science and Business Media B.V., 2021) Yücetepe, Aysun
In recent years, food scientists have made an intensive effort in order to obtain proteins from novel protein sources to meet nutritional requirements of human beings due to the increase in the world’s population. In particular, new protein sources such as macro- and microalgae with high protein contents could be used instead of conventional protein sources by food industry. Moreover, proteins extracted from macro- and microalgae and peptides derived from them possess potential benefits such as antioxidant, antihypertensive and anticancer activities on human health. On the other hand, their stability and bioactive effects can decrease under environmental and processing conditions such as pH, temperature, heat, oxygen. As a solution for this problem, encapsulation of algal proteins, protein hydrolysates and peptides with wall materials can protect their stability against destructive effects. In this context, the present chapter reviews the studies about chemical composition of macro- and microalgae, bioactive properties of algal proteins, protein hydrolysates or peptides and the effect of encapsulation techniques on their bioactive properties.
Effects of supplemental bee pollen on performance, meat quality, serum constituents and immunity system in growing quails
(South African Journal for Animal Sciences, 2021) Sevim, Behlül
This study focused on the effects of adding various levels of bee pollen to diets for Japanese quail (Coturnix coturnix Japonica). The response variables that were examined included their performance, carcass characteristics, meat colour, immune system, and some serum constituents. A total of 160 one-day-old quail chicks were used. These chicks were randomly assigned to four treatments, each consisting of 40 chicks. These groups were further divided into four replicates of ten birds. The treatments consisted of diets to which 0.0, 2.5, 5.0, and 10 g/kg bee pollen were added. The feeding period lasted 42 days. The performance and serum biochemistry of the growing quails were not affected by the addition of bee pollen to the diet. The addition of 5 g/kg bee pollen increased the follicle weight and the L* value of the breast, and decreased the a* value of the thigh. It also improved the serum immunoglobulin A (IgA) content. Thus, the addition of 5 g/kg bee pollen to the diet of growing quails was effective in improving follicle development, meat quality and immune system.
Rail-to-rail cmos voltage buffer design for lcd column drivers
(Institute of Electrical and Electronics Engineers Inc., 2021) Osmani, Festim; Arslan, Emre; Kıyak, İsmail
A high-speed rail-to-rail CMOS buffer amplifier with LCD column driver application and a very simple circuit structure, is proposed. The buffer employs a differential FVF at the input stage as a main circuit block as well as a smaller number of transistors compared to many other buffer designs. Advantages of this buffer compared to many others are low quiescent current, very small output impedance and a very small settling time characteristic. The main simulations have been performed using LTSpice with 0.35 μm CMOS technology parameters, whereas the layout is drawn using Microwind. The simulations reveal a result of 0.3 μs in terms of settling time with a power supply of 3.3 V while driving a 1 nF capacitive load and the quiescent current is found to be 3.95 μA. The buffer amplifier is also analyzed in terms of FOM (Figure-of-Merit) performance measure and compared to other previous published buffers, in which the proposed circuit shows an outstanding and better performance. Moreover, the robustness of the proposed circuit to process mismatches and tolerances are verified by Monte Carlo analysis
MOS-Only current mode filter design
(Institute of Electrical and Electronics Engineers Inc., 2021) Elmalı, Semih; Kızılırmak, Şafak Murat; Arslan, Emre
This work presents a current mode filter circuit that makes use of only the MOS transistors and its parasitic elements like the transconductance and gate-to-source capacitance. The core circuit, which shows the ac equivalent circuit, has only three MOS transistors. The proposed circuit has a very basic circuit structure and a small layout area. The main advantage of the proposed circuit, as compared to filters formed by the active and passive circuit elements, is the operating frequency range and also the cost. Using 0.35um AMS spice parameters, LTSpice simulations are performed. It is given that the simulation results are in harmony with the theoretical results.
