Performance and Blood Profile of Growing Pullets Fed Diets Supplemented with Cholecalciferol

Nutritional additives in animal production are often targeted at further improving productivity. Supplementation beyond the conventional requirement of animals however, may make or mar animals’ performance and well being. This study was conducted to assess the effects of dietary supplemental cholecalciferol on performance and blood profile of growing pullets. Bovan Brown pullets (n=128) aged 12 weeks and weighing 0.82±0.03 were allotted to four dietary treatments of four replicates and eight pullets per replicate in a completely randomised design. They were initially raised on an iso-caloric and iso-nitrogenous basal diet for the first three weeks and thereafter the diets were supplemented with 0 (T1), 1000 (T2), 2000 (T3) and 3000 IU/Kg D3 (T4), respectively. At week 20, final weight (kg) (1.19, 1.16, 1.18 and 1.15), weight changes (kg) (0.36, 0.34, 0.35 and 0.33), feed intake (0.89, 0.89, 0.89 and 0.89) and feed conversion ratio (2.48, 2.72, 2.57 and 2.79) for pullets on T1, T2, T3 and T4, respectively were not significantly affected (P>0.05) by the treatments. Platelet was the only haematological parameter that was significantly increased (P 0.05) affected by dietary D3 supplementation. The ALP, however was significantly higher (P 0.05) values of 17.57, 15.04 and 16.35 in pullets on 0, 1000 and 2000 IU D3 supplementations, respectively. The highest serum cholesterol (154.82), HDL (76.43) and LDL (69.59) levels were observed in pullets on supplemental 2000 IU D3 compared to other treatments while triglyceride was lowered (P<0.05) with increasing level of D3 supplementation from 82.58 in T1 to 45.59, 44.01 and 42.45 in those on 1000, 2000 and 3000 IU D3, respectively. Supplemental vitamin D3 in the diets of pullets had no gross effect on performance attributes and blood indices monitored.
Electronic and Photoelectron Spectroscopy: Ultraviolet photoelectron spectrum of CO

Concepts illustrated : vibrational structure and Franck–Condon principle; adiabatic and vertical ionization energies; Koopmans's theorem; link between photoelectron spectra and molecular orbital diagrams; Morse potentials . Carbon monoxide was one of the first molecules studied by ultraviolet photoelectron spectroscopy [1]. A typical HeI spectrum is shown in Figure 13.1. The spectrum appears to be clustered into three band systems. The starting point for interpreting this spectrum is to consider the molecular orbitals of CO and the possible electronic states of the cation formed when an electron is removed. Electronic structures of CO and CO + Any student familiar with chemical bonding will almost certainly be able to construct a qualitative molecular orbital diagram for a diatomic molecule composed of first row atoms. Such a diagram is shown for CO in Figure 13.2. The orbital occupancy corresponds to the ground electronic configuration 1 σ 2 2 σ 2 3 σ 2 4 σ 2 1 π 4 5 σ 2 . The σ MOs actually have σ + symmetry but it is not uncommon to see the superscript omitted. Since all occupied orbitals are fully occupied, the ground state is therefore a 1 Σ + state and, since it is the lowest electronic state of CO, it is given the prefix X , i.e. X 1 Σ + , to distinguish it from higher energy 1 Σ + states of CO. Consider the electronic states of the cation formed by removing an electron. If the electron is removed from the highest occupied molecular orbital (HOMO), the 5 orbital, then the cation will be in a 2 Σ + state.
An Investigation of Defected Ground Structure Effect on Bandwidth Enhancement of U-Shape Microstrip Antenna for Small Ultra Wide-Band Radar Device

Ultra-wideband radar has been widely used for various purposes, including detection of human vital signs, small displacement detection, and ground penetrating radar. In order to work properly, it requires an antenna with a wide bandwidth. This study reports an investigation of a bandwidth enhancement method by combining the U-shaped microstrip patch antenna with the Defect Ground Structure (DGS). In this research, the antennas are operated at 5.8 GHz. The results show the combination of U-shaped patch and DGS produce twice bandwidth performance compared to the one without DGS. In our study the diamond shape DGS gives the best performance among various DGS structures.
A Parallel FDTD/ADI-PE Method for Ultralarge-Scale Propagation Modeling of ILS Signal Analysis

In this letter, we propose a high-accuracy low-cost hybrid finite-difference time-domain (FDTD)/alternating-direction-implicit parabolic equation (ADI-PE) method for ultralarge-scale electromagnetic simulation on a distributed computing platform. The hybrid method offers fast and precise 3-D deterministic radio-wave propagation predictions in a difficult-terrain scenario with specific detailed structures in both near field and far field. Since the typical parallel ADI-PE method suffers from high-frequency data communication between different calculation cores, which greatly discount simulation efficiency in bandwidth-constrained environments, we adopt a Woodbury-formula-based parallel algorithm to find inverse matrixes of tridiagonal matrixes so that implicit and explicit steps of the PE can be finished in local computing cores. Simulation results for the instrument landing system (ILS) demonstrate the capability of the proposed method in achieving the state-of-the-art performance.

Water Requirements of ‘Meyer’ Zoysiagrass for Survival and Recovery After Prolonged Drought

Water restrictions on irrigation are generally not science-based and may cause irreversible damage to turfgrass or inadvertently waste water. The objectives of our study were to evaluate effects of minimum water applications to ‘Meyer’ zoysiagrass (Zoysia japonica Steud.) on 1) turfgrass performance during prolonged dry downs; and 2) survival and recovery thereafter. Zoysiagrass was watered with 0, 5, 10, 15, 20, 25, and 30% reference evapotranspiration (ET) replacement for two months in two consecutive summers under an automated rainout shelter (excluded all rainfall) near Manhattan, KS. Results indicated that irrigation at 20 to 30% ET slowed the decline in zoysiagrass performance compared with no water inputs. Irrigation at 30% ET maintained zoysiagrass at >75 percentage green cover (PGC) in the first year, and even with no water inputs (0% ET) or irrigation at only 5% ET replacement, zoysiagrass recovered after full irrigation resumed. In the second year, irrigation at 30% ET maintained zoysiagrass at >25 PGC throughout the dry down and it recovered thereafter, but plots with no water inputs (0% ET) or irrigated with 5% ET replacement only recovered to 30–42 PGC after 50 days of full irrigation. Water restrictions during severe droughts may conserve more water and reduce turfgrass damage by limiting irrigation of zoysiagrass to 20–30% ET than by using traditional standards such as allowing irrigation for only one day per week.
The influence of rapid pH decline and high muscle temperature on the water holding capacity and softness of beef

The research in this thesis had two aims. The first was to develop an instrumental method to measure the softness of raw meat and the second was to investigate the influence of rapid pH decline and high muscle temperature post-mortem on the water holding capacity (WHC, that is, the muscles' ability to retain fluid) and softness of beef. For the instrumental analysis of muscle softness, different Instron compression (IC) methods were compared to sensory evaluation (SE) of meat. The instrumental methods involved compression of small muscle blocks (approximate size 4x5x6cm) parallel and perpendicular to the muscle fibre direction at 20 mm depths and also attaching cylindrical cores of meat (4.5 cm diameter) to the compression head to prevent the samples from collapsing. The most suitable method was compression of muscle blocks perpendicular to the muscle fibre direction to 5 mm depth, as this method was able to show that rapid pH decline and high muscle temperature gave softer meat than slow pH decline at a lower temperature. However, this method did not correlate with the SE scores; the SE method was not able to differentiate the variation in softness between samples. It was hypothesised that rapid pH decline and high muscle temperature post-mortem would lead to increased protein denaturation, reduced WHC , accelerated meat tenderisation and shortening of sarcomeres and hence soft and exudative meat. It was also hypothesised that these effects would be dependent on the muscle fibre type. In one of the experiments, electrically stimulated (ES) beef Longissimus dorsi (LD) muscles were hot boned from the carcasses and incubated in 37 and 14 °C water baths until rigor. We found that the pH decline rate of the muscles subjected to the high temperature was almost double that of the medium temperature treatment with increased protein denaturation, softer muscles and lower WHC. There were no differences in the sarcomere length or tenderness on day 1 or day 3 due to the treatments to indicate accelerated tenderisation. Thus the hypotheses that rapid pH decline and high muscle temperature post-mortem would lead to accelerated tenderisation or sarcomere shortening and subsequently exudative meat were not supported.

Climate change has many effects on the environment and habitat. One of them is sea level rise, which may cause many people to be forced to leave their homes and may be homeless. Therefore, this study proposed a project that mixed-use component to address rising water challenges and the research centre for scientists to test, explore and come up with tangible solutions. Several case studies with similar research center were considered as the fundamental and idea development of the project. The components of the project consists of administration department, accommodation, recreational facilities, restaurants and bars, water sport and facilities, drop zone, health care facilities, commercial, and research centre. The site location of the project is located at North of Recife, Brazil, based on the site evaluation result with the criteria of location, accessibility, shape/ proportional, views, utilities, visibility, size, and environment aspects. The project encourages research on natural disasters, especially for floods and tsunamis.
Size-Dependent and Enhanced Photovoltaic Performance of Solar Cells Based on Si Quantum Dots

Recently, extensive studies have focused on exploring a variety of silicon (Si) nanostructures among which Si quantum dots (Si QDs) may be applied in all Si tandem solar cells (TSCs) for the time to come. By virtue of its size tunability, the optical bandgap of Si QDs is capable of matching solar spectra in a broad range and thus improving spectral response. In the present work, size-controllable Si QDs are successfully obtained through the formation of Si QDs/SiC multilayers (MLs). According to the optical absorption measurement, the bandgap of Si QDs/SiC MLs shows a red shift to the region of long wavelength when the size of dots increases, well conforming to quantum confinement effect (QCE). Additionally, heterojunction solar cells (HSCs) based on Si QDs/SiC MLs of various sizes are presented and studied, which demonstrates the strong dependence of photovoltaic performance on the size of Si QDs. The measurement of external quantum efficiency (EQE) reveals the contribution of Si QDs to the response and absorption in the ultraviolet–visible (UV-Vis) light range. Furthermore, Si QDs/SiC MLs-based solar cell shows the best power conversion efficiency (PCE) of 10.15% by using nano-patterned Si light trapping substrates.
A Small-Size K-Band SPDT Switch Using Alternate CMOS Structure With Resonating Inductor Matching

A single-pole double-throw (SPDT) CMOS switch at 15–25 GHz is presented, which has a small size, low insertion losses, and high-power handling capabilities for both output nodes. It has an SPDT structure in which nMOS and pMOS are alternately used as series and shunt transistors. An inductor-matching network is placed between two output nodes for input and output matching, which is also used to increase isolation by resonating out the off capacitances. The proposed SPDT switch is fabricated using a 28-nm CMOS process. It achieves an insertion loss of less than 1.9 dB from 15 to 25 GHz. The measured IP0.2dB of two outputs is 17.4 and 18.3 dBm, respectively. It has an isolation of 25 dB at 20 GHz. The measured ON/OFF switching time is less than 2.3 ns. The proposed SPDT switch has a core area of only 0.02 mm2.
Stability-Indicating HPLC Methods for the Quantification of Cyproheptadine Hydrochloride, Vitamins B1, B5 And B6 in Tablets using RP-HPLC with UV Detection

The availability of reliable and fast analytical method is crucial for the quality control of multi-API in a single dosage form. Herein, two methods have been developed and validated for the determination of Cyproheptadine hydrochloride (CH), Thiamine mononitrate (Vit. B 1 ), Calcium pantothenate (Vit. B 5 ) and Pyridoxine hydrochloride (Vit. B 6 ) in uncoated tablets. To assay the vitamins, a mobile phase combination of Phosphate buffer pH 3.5 and Methanol in the ratio 93:7, using Eurospher ODS (150 x 4.5mm) as the stationary phase with a flow rate set at 1.0 mL/min at ambient temperature conditions was adopted. Wavelength of detection was 270 nm with a run time of 0.00 to 5.50 minutes for Thiamine mononitrate and Pyridoxine hydrochloride, and 205 nm from 5.50 to 11.00 minutes for Calcium pantothenate. A good resolution and a short run time of 11 minutes were achieved with the validated conditions. The retention times of Thiamine mononitrate, Pyridoxine hydrochloride and Calcium pantothenate were 2.823±0.020, 4.184±0.007 and 10.025±0.015 respectively. The mobile phase for Cyproheptadine HCl was methanol and an ion-pairing solution (70:30), set at a flow rate of 1mL/min, a runtime of 8 minutes, an injection volume of 20 µL and a wavelength of 285 nm using Eurospher ODS (150 x 4.5 mm) as the stationary phase. The retention time for Cyproheptadine HCl was 4.961±0.006. Both methods were found to be specific, robust, accurate and precise over the concentration ranges of 0.0192 mg/mL–0.0288 mg/mL for Thiamine mononitrate, 0.0128–0.0192 mg/mL for Pyridoxine hydrochloride, 0.032–0.048 mg/mL for Calcium pantothenate and 0.032-0.048 mg/mL for Cyproheptadine hydrochloride. The Correlation Coefficient (r 2 ) for Cyproheptadine hydrochloride, Thiamine mononitrate, Pyridoxine hydrochloride and Calcium pantothenate were greater than 0.999. The purpose of this study was to develop and validate simple HPLC methods for the estimation of Cyproheptadine hydrochloride, Vitamins B 1 , B 5 and B 6 in combined dosage forms. The proposed methods were found to be precise, specific, accurate and robust for the estimation of Cyproheptadine hydrochloride, Vitamins B 1 , B 5 and B 6. Keywords: Cyproheptadine hydrochloride, Thiamine mononitrate, Pyridoxine hydrochloride, Calcium pantothenate, RP-HPLC, Validation DOI: 10.7176/CMR/12-6-06 Publication date: August 31 st 2020
Multi-Context TCAM-Based Selective Computing: Design Space Exploration for a Low-Power NN

In this paper, we propose a low-power memory-based computing architecture, called selective computing architecture (SCA). It consists of multipliers and an LUT (Look-Up Table)-based component, that is multi-context ternary content-addressable memory (MC-TCAM). Either of them is selected by input-data conditions in neural-networks (NNs). Compared with quantized NNs, a higher accurate multiplication can be performed with low-power consumption in the proposed architecture. If input data stored in the MC-TCAM appears, the corresponding multiplication results for multiple weights are obtained. The MC-TCAM stores only shorter length of input data, resulting in achieving a low-power computing. The performance of the SCA is determined by three physical parameters concerning the configuration of MC-TCAM. The power dissipation of the target NN can be minimized by exploring these parameters in the design space. The hardware based on the proposed architecture is evaluated using TSMC 65 nm CMOS technology and MTJ model. In the case of speech command recognition, the power consumption at the multiplication of the first convolutional layer in a convolutional NN is reduced by 67% compared to the solution relying only on multipliers.
The Role Of Income Inequality In The Globalisation-Poverty Nexus: Empirical Evidence From Mint Countries

Theoretical claims about the globalisation-income-poverty nexus suggest that globalisation generally reduces poverty, since more integrated economies tend to grow faster and this growth is usually diffused. In view of this, the study empirically analyses the relationship between poverty (absolute and multidimensional) and the various dimensions of globalisation (economic, social and political) in MINT countries (Mexico, Indonesia, Nigeria and Turkey) from 1980 to 2018, using a dynamic generalised method of moments (GMM) estimation technique. The key findings are as follows; (i) income inequality influences the nexus between political globalisation and poverty level in Mexico and Indonesia, and also influences the relationship between social globalisation and poverty level in Turkey, (ii) income inequality does not affect the relationship between all three dimensions of globalisation and poverty in Nigeria, and (iii) with the exception of Turkey, income inequality increases the level of poverty in MINT. Thus, as a policy recommendation, it is recommended that governments of MINT countries should embark on activities that would help in achieving equal distribution of income to benefit from the gains of globalisation in terms of poverty reduction.
Analysis of Acoustic Feedback Cancellation Systems based on Direct Closed-Loop Identification

—This work presents, using the least squares esti- mation theory, a theoretical and experimental analysis on the performance of the standard adaptive ﬁltering algorithms when applied to acoustic feedback cancellation. Expressions for the bias and covariance matrix of the acoustic feedback path estimate provided by these algorithms are derived as a function of the signals statistics as well as derivatives of the cost function. It is demonstrated that, in general, the estimate is biased and presents a large covariance because the closed-loop nature of the system makes the cross-correlation between the loudspeaker and system input signals non-zero. Simulations are carried out to exemplify the results using speech signals, a long acoustic feedback path and the recursive least squares algorithm. The results illustrate that these algorithms converge very slowly to a solution that is not the true acoustic feedback path. The relationship between the performance of the adaptive ﬁltering algorithms and the aforementioned cross-correlation is proven by varying the signal- to-noise ratio and the delay introduced by the forward path.
Improved visualization of DNA in aqueous buffer with the atomic force microscope

An improved method has been developed for imaging deoxyribonucleic acid (DNA) in aqueous buffer with the atomic force microscope (AFM). DNA on untreated mica can be imaged in aqueous buffer with the AFM if the DNA is deposited onto the mica in a buffer with HEPES and MgC12 , if the sample is rinsed thoroughly with high water pressure, and if the imaging is done with an electron beam-deposited (EBD) tip that has been deposited in the scanning electron microscope (SEM). The water rinse removes DNA that is otherwise easily scraped off the substrate. There is evidence that sharper tips may be more damaging to DNA when imaged in aqueous buffer especially when the DNA is bound tightly to the mica. The ability to image DNA in nearly biological conditions has potential applications for imaging biomolecular processes with the AFM.
Haptic Tutor - A haptics-based music education tool for beginners

In this paper we introduce Haptic Tutor, a wearable haptic system for triggering vibrations on limbs of a student drummer aimed to help develop multi-limb independence. The system uses portable, wireless vibrotactile devices to display haptic information on drummers' limbs. To asses the usefulness of the system, we analyse response time differences between stimuli and motor action (drum stroke). Our hypotheses are that the use of haptic stimuli will improve the temporal characteristics of performances, but also that the type of haptic stimuli will have an influence on performance results. To validate these hypotheses we conducted two experiments. The first one with participants randomly distributed in three groups, each group performing simple drumming lessons involving both hands under a given condition (no haptics, haptic pulse and haptic ramp). Results show clear improvement in strike accuracy for both haptic conditions, most clearly in the haptic ramp condition. Using these results, a second experiment was carried out in which 6 other participants were randomly divided into two groups (no haptics and haptic ramp conditions) and asked to perform a more complex lesson, this time involving three limbs (two arms and right foot). Results of both experiments show clear improvement on strike accuracy (reduced asynchrony), but a less important difference on strike precision (inter-onset-interval deviation) for the haptic condition. We finally report on participants subjective comments , discussing the limitations of the current prototype.
Exogenous 24-epibrassinolide alleviates the detrimental effects of suboptimal root zone temperature in cucumber seedlings

ABSTRACT Suboptimal root zone temperature (RZT) is major hurdle for vegetables production that causes a remarkable reduction in growth and yield during winter and early spring. The aim of this study is to assess the effects of 24-epibrassinolide (EBR) on physiological and biochemical mechanism on cucumber seedling under suboptimal RZT. The treatments were NT (normal RZT [22 ± 2°C]), LT (suboptimal RZT [14 ± 2°C]), EBR (0.1 µM EBR + suboptimal RZT [14 ± 2°C]) and BZR (brassinazole, a specific EBR biosynthesis inhibitor) (4 µM BZR + suboptimal RZT [14 ± 2°C]). The results showed that LT and BZR significantly decline cucumber seedlings growth, chlorophyll (Chl) contents, photosynthetic capacity, antioxidant enzyme activities and nutrients accumulation. Exogenous EBR application significantly enhanced cucumber seedling growth, Chl contents, photosynthetic capacity, nutrient contents, activities of antioxidant enzymes and reduced the contents of H2O2 (hydrogen peroxide), (superoxide radical) and malondialdehyde. The transcript levels of EBR-biosynthesis genes are reduced by LT, while reported significantly higher in EBR treated seedling. Our results suggest that exogenous EBR could alleviate the harmful effects of suboptimal RZT by modulating EBR-biosynthesis genes expression and antioxidant, nutrient, Chl and photosynthetic machinery, thus leading to improved plant growth.
