Combination of wet fixation and drying treatments to improve dye fixation onto spray-dyed cotton fabric
No full textAbstract The conventional dyeing process requires a substantial amount of auxiliaries and water, which leaches hazardous colored effluents to the environment. Herein, a newly developed sustainable spray dyeing system has been proposed for cotton fabric in the presence of reactive dyes, which has the potential to minimize the textile dyeing industries environmental impact in terms of water consumption and save significant energy. The results suggest that fresh dye solution can be mixed with an alkali solution before spray dyeing to avoid the reactive dye hydrolysis phenomenon. After that, drying at 60–100 °C, wet fixation treating for 1–6 min, and combined treatments (wet fixation + drying) were sequentially investigated and then dye fixation percentages were around 63–65%, 52–70%, and above 80%, respectively. Following this, fixation conditions were optimized using L16 orthogonal designs, including wet fixation time, temperature, dye concentration, and pH with four levels where the “larger-the-better” function was selected to maximize the dye fixation rate. Additionally, the color uniformity and wash and rubbing fastnesses were at an acceptable level when both treatments were applied. Finally, the dyes were hydrolyzed after wet fixation, and the hydrolysis percentages were enhanced after the drying process
Evaluation of the efficiency of the aqueous and alcoholic extract of Propolis in reducing the incidence of Nosema cerana disease on Apis mellifera honey bees
No full textAbstract The results of the study showed the superiority of the alcoholic extract of propolis in reducing the infection of Nosema on honey bees to the lowest levels, as it reduced the number of spores to the lowest possible number, especially when using treatment with protein feeding, with an average of 214.20 spores / bee, which reflected positively on the physiological and vital characteristics of the bee's body (age of the bee). Rectal acidity, moisture content of the bee's body, and fat content of the bee's body) which these characteristics are considered as evidence of the health of the bee's body, with averages of (50.10 days, PH 4.95, 64.52%, and 81.60%), respectively, which did not differ significantly from the percentages of most of the above traits. The male of the extract, but when adding the treatment with sugary nutrition, followed it in reducing the infection rate when using the treatment with the aqueous extract, which achieved good and satisfactory results, while the infection was high and the coefficients values were low in the comparison treatment, and the highest average number of spores was 2988.70 spores / bee, which was reflected negatively on the physiological characteristics, vitality, activity, and health of honey bees, which amounted to (21.10 days, PH 5.85, 89.74%, and 5.95%), respectiv
اردو ناول ’’نمبردار کا نیلا‘‘ اور تشکیلی حقیقت
No full textIn the study of Postmodern Discourse, French sociologist, Baudrillard discovered hyper-reality in the system of signs and symbols associated with language. In hyper-reality desired reality is created against the actual reality. It is a system that is influenced by symbols, metaphors, models, machines, maps, images, cyber worlds and information system. This system is so powerful that it can mould the fiction into reality. Novelty of Sayed Muhammad Ashraf's novel “Numbardar Ka Nila” is based on hyper-reality. In this novel Numbardar is the symbol of powerful class, those who demonstrate power and all the institutions that make and enforce the law seem to play the role of facilitator for them. By using his powers, Numbardar is skilled enough to mould the reality as he desires to maintain the existence of his colonialism. Novel is based on hyper-realities
فارس اور وسط ایشیاء میں غالب شناسی
No full textThe tradition of Ghalib Shanasi ( Ghalib Cognizance ) is as old as the literary work of Ghalib itself. Ghalib has left behind himself a highly esteemed literary work of Persian poetry and prose. But despite that the tradition of Ghalib Shanasi ( Cognizance of Ghalib ) among the literary scholars of Persia started too late, near about, in 1950. Though Ghalib was appreciated in Persian literary intellectuals but this appreciation is not sufficient as compare to the discernment of Ghalib among the literary craftsmen of Urdu. Therefore, paradoxically, Ghalib felt pride in expressing himself in Persian and he thought himself as the literary figure of that language. Among the Persian literary figures, thesis of Dr. Muhammad Muqaddam Alvi, Dr. Shafei Kadkani, Professor Estelami, Dr. Raza Mustafa and Yahya Taliban regarding Ghalib Shanasi (Cognizance of Ghalib). The research work and criticism of Muhammad Hassan Jairi, Sayed Ghulam Akbar Naqvi and Muhammad Ali Farjaad etc., regarding Ghalib Shanasi ( Ghalib cognizance ) are worthy to be acknowledged. Though they compensate Persian's lack of Ghalib Shanasi (Ghalib Cognizance), yet more is required to be done
Efficiency of some vegetative powders and storage method in controlling the Great wax moth Galleria melloella L.
No full textThe studies were conducted in the apiary laboratory, apiary store and the external shed of the Plant Protection Department/Department of Plant Protection/College of Agriculture and Forestry/Mosul University during the year 2019-2020. Before using plant powders (black arum, oleander, and cinnamon) to control the wax moth, the effect of the powders on honeybee colonies was tested. The results did not show any negative effect of the powders under study on bees, and bees mortality as a result of treating frames with powders were not recorded. As for the effect of plant powders on the wax-moth, the results showed the lethal effect of plant powders (black arum, oleander and cinnamon) on the Wax moth larvae stage in the laboratory. All plant powders led to satisfactory mortality rates after a week of treatment, especially the black arum powder treatment which differed from the other treatments, and recorded the highest mortality rate of 83.3%, followed by oleander powder with a mortality rate of 63.3%, then cinnamon powder treatment which resulted in the lowest mortality rate of 50.0% during the same period. It was noted that mortality rates differed among treatments for different dates. Interaction treatment of black arum powder and outdoor storage method with leaving a space between frames after a week of treatment recorded the highest mortality rate which was. The rates of larval mortality varied according to the method of storage, arranging the frames and the dates of data recording. Natural mortality rates of insect larvae were recorded in the control treatment, especially in outdoor storing frames, when leaving a space between frames. The control treatment did not record any natural mortality for larvae when using the storage method inside the store, regardless of the distance between frames or the dates of data recording
Simulation-based metrological temperature ensuring and control of the temperature field in an induction furnace based on various parameters
No full textInduction heating is widely used in industrial furnaces because of its rapid response time and high energy efficiency. To design and optimize these furnaces, computer-aided simulations are essential. This study aims to develop an accurate temperature field model for a square cross-section steel billet in an induction furnace by leveraging various parameters in COMSOL Multiphysics software. The simulation analysis incorporated temperature dynamics, considering skin depth, temperaturedependent, and constant parameters of the steel billet. The datadriven model was converted into a state-space representation utilizing MATLAB's System Identification Toolbox. This conversion facilitated the design of a Linear Quadratic Regulator (LQR) with integral gain and pole placement. Further, these controllers' performance was analyzed, and controllers were successfully implemented to regulate the temperature field of the billet from initial temperature to reference temperature, utilizing the distributed parameter system control circuit.Slovenská technická univerzita v Bratislave, STU; Agentúra na Podporu Výskumu a Vývoja, APVV, (APVV-21-0216, APVV-21-0195, APVV-22-0436); Agentúra na Podporu Výskumu a Vývoja, APVV; Ministerstvo školstva, vedy, výskumu a športu Slovenskej republiky, (KEGA-024STU-4/2023); Ministerstvo školstva, vedy, výskumu a športu Slovenskej republiky; Vedecká Grantová Agentúra MŠVVaŠ SR a SAV, VEGA, (1/0675/22); Vedecká Grantová Agentúra MŠVVaŠ SR a SAV, VEGAFaculty of Mechanical Engineering, Slovak University of Technology in Bratislava, Slovak Research and Development Agency [APVV-21-0195, APVV-21-0216, APVV-22-0436]; Cultural and Educational Grant Agency of the Ministry of Education of Slovak Republic [KEGA-024STU-4/2023, VEGA 1/0675/22, 21NRM05

Two cultures, one room: investigating language and gender in Kuwait
No full textPhDKuwait is a gender-segregated country. Its conservative cultural ideology is evident in all
areas of social life, including the way people communicate. Men and women have to
make conscious language choices during everyday interaction. Certain aspects of Kuwaiti
conversational registers are exclusive to either men or women, which reflects not only
men’s and women’s separate socialization as children but also separate lifestyles as
adults. Kuwait’s gendered context is therefore bound to be unique and of particular
sociolinguistic interest, especially since mainstream language and gender literature has
more often focused on English-speaking cultures. Thus, there is little knowledge of Arab
gender-segregated cultures and this could possibly be due to complications that the
researcher inevitably encounters when examining a sensitive issue such as gender within
these constraints. The present research study investigates mixed interaction between
Kuwaiti men and women in online chat rooms. In this particular online context, chat
room users employ interactional strategies to negotiate the norms of heterosexual
interaction which are often non-existent in offline Kuwaiti society. A combined
framework of sociolinguistic, ethnographic methods is adopted to examine chat room
interactional choices that enable men and women to construct gendered chat room
identities as well as create a virtual online community of practice without undermining offline gender norms
