Applying additive-modifiers in dewaxing raffinate process

Dewaxing petroleum oil raffinates is carried out by low-temperature rectification in sovents acetone – toluene. To intensify the process as an additive-modifier we used ε -caprolactam. Analysis of structural-group composition dewaxed raffinate by infrared spectroscopy showed that in the presence of ε -caprolactam selectivity of dewaxing is increased due to smaller content slack aromatic, branched paraffins and oxygenates structures. However, if the content of ε -caprolactam > 1 wt % selectivity of separation is reduced, apparently by increasing solvent power system acetone – toluene ( ε -caprolactam)

Hydroxyapatite and Titania (HA-TiO2) powder mixed EDM for surface modification.

Titanium dioxide (TiO2) is remarkable in biomedical field since its applications by surface modifications on metallic implant can prevent release of metal ions after long exposure to body fluids. Its combinations with hydroxyapatite powder can further enhance the biocompatibility as well as mechanical properties of implants. In this study we aimed to apply surface modification on stainless steel by powder mixed EDM using HA and TiO2 powder. It was found that material removal rate for the experiments conducted was higher than its respective electrode wear rate which indicate proper EDM as well as surface modification were successfully done. However, further analysis is required to determine the uncertainties of the surface modifications like its surface topography, surface roughness as well as elements and oxide compounds deposited

A white woman stories to decolonise (herself).

This bricolage of writings is the result of a middle-class, middle-aged white privileged woman who jettisoned (most of) her motherly and housewifely duties to explore her social conscience in a scholarly but creative way. I call it my passion PhD as I meander through the cultural abyss between black and white Australia for the sheer love of learning, luxuriating in research, trying to see what I had never been shown, and unsee what I had been shown. I wonder how can I be complicit and complacent in a society that privileges me over others because of the colour of my skin? I combine a creative practice of storytelling to question the status quo that is the dominant culture, the mercurial methodology of poetics, and the autoethnographic eye that guides a reflexive process of personal decolonisation. I bring to the research a burgeoning awareness of colonised minds, bodies, spirits and lenses and am confident my fresh eyes, curiosity and commitment to unlearn, unsee and unsettle can be deftly deployed to challenge and disrupt the prejudices and perceptions of my fellow white Australians. This is not a problem-solving piece of research, although I am exploring the nature of a problem. The problem.  which is often erroneously cast as the `Aboriginal Problem' when it is a Whiteness Problem, is the core of my research. But I am not focusing just on First Nations peoples and their legacy of colonisation; rather, I examine our shared legacy, turning the gaze back on white Australia, holding up a mirror, to ask with all sincerity: Who is the problem? Where is the problem? What have we done? Why weren't we told? Did you really just say that? The space I am writing into is the denial that W. E. H. Stanner called `The Great Australian Silence', `the cult of forgetfulness practiced on a national scale' (1968) and it remains disappointingly relevant today. I follow those historians who have sought to open white Australian ears and hearts to our violent history and the true legacy of colonisation, including Bernard Smith, Henry Reynolds, Ian Clark, Minoru Hokari, Lyndall Ryan and Inga Clendinnen, to name a few. I respectfully listen to and follow the lead of First Nations scholars from other colonised nations who have demanded from the academy the right and space to create research and methodologies in their own cultural shape, foregrounding their own ways and knowing and being, such as Linda Tuhiwai Smith, Jo-Ann Archibald, Michael Yellow Bird, Richard Frankland, Natalie Harkin and Aileen Moreton-Robinson. I submit my whiteness to scrutiny to `undo', or unravel, this identity to which I have been so accustomed and that has afforded me so much. In this task, I see myself through the gaze of critical race scholars like George Yancy, Robin DiAngelo, Shannon Sullivan and poet Claudia Rankine and emerge chastened. I lean on the scholarship of my creative contemporaries who write from deep in their hearts and bellies to advocate for a society that is better than this, that we are better than this, for Treaty, for self-determination, for Change the Date, for a First Nations voice to Parliament. I am inspired by, and add my voice to the works of Stephen Muecke, Deborah Bird Rose, Anne Elvey, Katrina Schlunke and Michael Farrell. What you have in your hands are six chapbooks, each painted in a hue from Boon wurrung Country, filled with stories about my peering into and trying to work out ways to bridge the cultural abyss to discover how I might write about white relationships with black Australia in a way that engages white Australia to listen

Estimation of genetic parameters for egg production traits in Japanese quail that selected for immune responses and fed different level of dietary L-arginine

This study was conducted in the fields of the Department of Animal Production - College of Agriculture at Kirkuk University for the period from 6/14/2021 to 7/30/2022. 750 quail chicks were supplied from the Poultry Research Station of the Agricultural Research Department in Abu Ghraib. The chicks were fed the starter ration until the age of 30 days, and then they were fed the production ration. At the age of 4 weeks, the chicks were vaccinated with the attenuated Newcastle vaccine, and the chicks were divided into six experimental treatments: the first treatment represented the negative control group that was not vaccinated and did not have the amino acid arginine added to it, the second treatment represented the positive control group whose chicks were vaccinated with the Newcastle vaccine with no arginine added to their diet As for the third and fourth treatments, they were vaccinated with the Newcastle vaccine with the addition of 5% arginine higher than the bird''s needs. The fifth and sixth treatments represented groups of birds vaccinated with the Newcastle vaccine, while feeding the birds with diets to which the amino acid arginine was added, 10% higher than the bird''s needs. A week after the initial immunization, the bird was vaccinated again with Newcastle vaccine, and the immune level was examined by the agglutination test to find out the level of the birds'' immune response, dividing them into two levels of high immune response and low immune response. This process was repeated for the next three generations. The characteristic of egg production at the age of 90 and 120 days, and the egg mass was recorded. The data were analyzed according to the general linear model method using the ready-made statistical program SAS. The genetic equivalent and the genetic and phenotypic correlations were estimated. The characteristics of egg production decreased until the age of 90 and 120 days, as well as the mass of eggs at the age of 120 days, compared to the base population (21.61 vs. 34.84), (22.01 vs. 26.53), (323.47 vs. 545.97), respectively. The egg mass was significantly affected by the level of immunity and the percentage of added arginine, where the highest value of the egg mass was for birds selected for the high immune level and to which arginine was added by 10% higher than the needs of the bird. Estimates of genotyped egg production at 90 and 120 days of age and egg mass at 120 days of age were (0.64, 0.65 and 0.21), respectively. The results showed weak genetic correlations (0.0263) between egg production at the age of 90 days and egg production at the age of 120 days, but the phenotypic correlations were high (0.6248) between egg production at the age of 90 days and egg production at the age of 120 days. The current study indicates that the selection of birds according to the immune response against Newcastle disease led to decrease in egg production and egg mass. Addition the Arginine amino acid did not increase production at the age of 90 and 120 days. While the addition of arginine 10% led to an increase in the egg mass

Effect of dietary supplementation with rocket salad (Eruca sativa) seeds powder on testis histological traits of roosters subjected to oxidative stress induced by hydrogen peroxide

This study was conducted to evaluate the effect of adding rocket salad seeds powder to the diet on testis histological traits of roosters subjected to oxidative stress induced by hydrogen peroxide. A total of 60 Hy – line laying breeder roosters 57 weeks old were used in this study. Roosters were randomly distributed on 5 treatments with 3 replicates each treatments were as follows: T1: males were fed control diet and normal water, T2, T3, and T4: males were fed control diet supplemented with 3 gm rocket salad powder / kg of diet + 0.25 ml hydrogen peroxide 0.5%/ litter of water, 0.5 ml hydrogen peroxide 0.5%/ litter of water, and 1 ml hydrogen peroxide 0.5%/ litter of water, respectively. The T5: males were fed control diet and drank water supplemented with 1 ml hydrogen peroxide 0.5%/ litter of water. Males were treated with hydrogen peroxide 6% and rocket salad for 12 weeks starting from 59 week of ages. Results revealed that water supplementation with hydrogen peroxide without adding rocket salad powder to the diet (T5) resulted in significant deterioration as regards testis weight, measurements of seminiferous tubules, and volume density and relative weight of active components of seminiferous tubules and interstitial tissue as compared with T1 group. However, supplementing the diet of roosters subjected to oxidative stress induced by hydrogen peroxide with rocket salad seeds powder (T2, T3, and T4) resulted in significant improvement concerning histological traits involved in this experiment in comparison with T5 group. In conclusion adding rocket salad powder to the ration of roosters could limit to a considerable extent the damages on histology of the testis that originate from oxidative stress. Therefore, rocket salad powder could be used as one of active tools for improving reproductive performance of roosters

Evaluation of Extreme Rainfall Occurrences Using Short-term and Long-term Standard Precipitation Index (SPI)

The main objective of this study is to investigate the Standard Precipitation Index (SPI), a method commonly used to determine extreme rainfall occurrences. It is also used to gauge the severity and duration of drought in meteorological studies. To highlight exceptional extreme rainfall events in selected areas, a methodology for calculating the SPI was provided in this paper using a range period and thresholds. The Standard Precipitation Index (SPI) is used to analyze monthly precipitation data from several selected rain gauge stations between 1970 and 2014. The goal of this study is to monitor the extremely moist conditions that may eventually lead to flooding. Precipitation index data from several rain gauge sites in the selected region are used to calculate the SPI time series. Additionally, SPI readings for 3 months or less may usually be used for basic drought monitoring, values for 6 months or less may be useful for monitoring agricultural impacts, and values for 12 months or more may be useful for monitoring hydrological impacts. In this study, two states affected by the monsoon season were selected: Johor and Kelantan. Two rain gauge stations were selected from these two states to calculate the SPI results. From this study, statistics on the occurrence of dry and wet events in specified areas were determined based on the SPI readings for 3-month, 9-month, 12-month, and 24-month periods. To summarize, this research demonstrates the potential of SPI to enhance our understanding of extreme rainfall events in Peninsular Malaysia

Effect of Dietary Linseed on Egg Quality of Laying Quail

Abstract: This experiment was performed to investigate the effect of dietary supplementation with linseed on egg quality of laying quail. A total of 320 Japanese quail (Coturnix coturnix japonica) 9-wk old were allocated to 4 treatment groups with 4 replicates containing 20 quail each. Birds were fed commercial diet containing 0% (C), 2% (T1), 4% (T2) or 6% (T3) linseed. Birds received water and diet ad libitum during the total period of experiment. Egg quality characteristics were monitored over 3 consecutive 21-d periods. Egg quality criteria involved in this experiment were egg weight, yolk diameter, yolk height, yolk weight, albumen height, albumen weight, shell weight, shell thickness, Haugh unit, albumen percentage, yolk percentage and shell percentage. Results revealed that supplementing diet of laying quail with linseed resulted in significant increase in total means of egg weight, yolk diameter, albumen height, shell thickness, Haugh unit, albumen percentage and albumen weight. Total means of shell weight and yolk percentage were not significantly (p>0.05) different from quails consuming 0, 2, 4 or 6% linseed; However, total mean of shell percentage was reduced (p<0.05) in laying quails fed linseed when compared to control group. In conclusion, Feeding laying quails with different levels of linseed (2%, 4%, or 6%) caused significant improvement as regards most of egg quality parameters included in this experiment. Therefore, adding linseed to the ration could be used as a good tool for improving productive performance of Japanese quail
