Dyeing studies with henna and madder: A research on effect of tin (II) chloride mordant
The present paper deals with the application of natural dyes extracted from powdered henna (Lawsonia inermis) leaves and madder (Rubia cordifolia) roots on woolen yarn and assessment of effect of stannous chloride mordant on dyeability, color characteristics, fastness properties and antifungal activity of dyed woolen yarn. Sixteen shades have been developed for the characterization of their color characteristics and fastness properties. The color strength (K/S value) has been found to be very good in all dyed woolen yarn samples. The color fastness with respect to light exposure, washing and rubbing was quite satisfactory for both henna as well as madder dyed samples. Henna leaves extract was found very effective against Candida glabrata both in solution as well as after application on wool substrate but no antifungal activity is reported in case of madder both in solution as well as on wool substrate
Problems and Prospects of Islamic Banking: a case Study of Takaful
The paper is an attempt to analyse the working of Takaul in the world and its popularity in the insurance sector in the world. Keeping in view of Sharia we have also tried all possible aspects of insurance system popular in the world and tried to look at its possibility to familiarize more amongst Muslims of the world. It is observed that customer awareness remain low, however this is often attributed to a limited understanding of Islamic finance in the banking and insurance world. We wish to have a proper salesmanship and advertisement of Islamic banking system in India and all around the world.Islamic Banking, Takaful
Information technology and cost efficiency in Malaysian banking industry
It is argued that information technology can increase cost efficiency of banks by offering opportunities to substitute across inputs into production – for example, to substitute computer technology and information networks for labor. Hence, the transition to a knowledge-based financial sector would lead to banks becoming more competitive, more cost effective and better able in managing risks. As such, those
banks that failed to make this transition are less able to compete as they lack the capability to innovate
and face higher delivery costs. The main objectives of this paper are to determine the impact of IT on banking efficiency and its economies of scale using a sample of Malaysian banks. To achieve these objectives, stochastic cost frontier method is employed to estimate bank efficiency and panel data approach were used to examine the impact of IT on bank efficiency. The results indicate that the impact of IT on bank efficiency increases with increase in bank size, hence further supporting the process of bank mergers that are currently undertaken in the Malaysian banking industry
Collaboration among teachers in inclusive special education program classrooms
Collaboration between teachers and special education teachers is a vital factor in ensuring the success of the implementation of the Inclusive Education Programs especially in the teaching and learning aspects. Until 2016, there is no detailed document or information regarding how the collaboration is conducted or implemented in the inclusive classrooms. Therefore, this study is aimed to explore how collaboration is conducted and implemented in the Inclusive Special Education Program classrooms, particularly identifying the stage of collaboration the school are at and approach used in the inclusive classrooms. To achieve this, a survey questionnaire was used as an instrument for this study and it is conducted on 53 schools and 441 participants including headmasters, senior assistant principals for special education teachers, subject teachers and special education teacher. Results showed that most of the participants are at the “Starting a partnership” stage (mean score = 4.165, SD = 0.797). The type of collaboration approach that are usually being used is the “collaboration-consultation” approach (mean score = 4.10, SD = 0.721). This suggests that more action is needed to ensure the successful implementation of an inclusive program. This is because without done the recommended steps of collaboration, the inclusive may not carried out effectively. A successful inclusive classroom also can be achieved through multiple approaches of collaboration are implemented. Therefore, knowledge about steps and approaches of collaboration should be knowledgeable to general, special education teacher and also school administrators
Herlyn-Werner-Wunderlich syndrome : a rare genitourinary anomaly in females : a series of four cases
We present case series of four patients with an important syndrome known as Herlyn-Werner-Wunderlich syndrome. Herlyn-Werner-Wunderlich syndrome is a rare congenital anomaly characterised by uterus didelphys with blind hemivagina and ipsilateral renal agenesis. It usually presents after menarche with progressive pelvic pain during menses secondary to haematocolpos. Awareness is necessary to diagnose and treat this disorder properly before complications occur. Magnetic resonance imaging is the preferred modality for the delineation of uterine malformation. When renal anomalies are encountered, a screening should also be made for congenital abnormalities of the reproductive tract and vice versa
Keselamatan jalan raya : di mana kita?
Malaysia mencatat kemalangan jalan raya pada kadar 200,000 kejadian setahun dari 1995 hingga 1998. Bagi tempoh yang sama, mangsa kemalangan berjumlah 54,475 orang dengan kadar kematian seramai 6,016 cedera parah 13,926 dan cedera ringan 34,533 orang. Bilangan kenderaan yang rosak akibat kemalangan jalan raya berjumlah 335,571 unit. Lebih daripada 95% kemalangan dan kematian berlaku di jalan raya negeri dan persekutuan berbanding lebuh raya. Kos kemalangan jalan raya dianggarkan melebihi RM 6.0 billion setahun. Pada 2000, nisbah kemalangan maut per 10,000 kenderaan menunjukkan perubahan yang baik iaitu 5.51% berbanding dengan tahun-tahun sebelumnya. Sebaliknya, nisbah kemalangan maut per 100,000 penduduk menunjukkan perubahan yang kurang memuaskan iaitu 27.01% berbanding dengan tahun-tahun sebelumnya. Keselamatan jalan raya di Malaysia agak membimbangkan negara maju seperti Britain (6.1%), Jerman (9.5%), Australia (9.4%) dan Jepun (8.5%). Kertas ini membincangkan beberapa strategi menangani keselamatan jalan raya yang dilaksanakan di beberapa negara termasuk Malaysia. Kertas ini akan mengutarakan konsep audit keselamatan jalan raya sebagai salah satu strategi penting bagi menangani keselamatan jalan raya di Malaysia
Dyeing studies and fastness properties of brown naphtoquinone colorant extracted from Juglans regia L on natural protein fiber using different metal salt mordants
In this study, wool fibers are dyed with a natural colorant extracted from walnut bark in presence and absence of mordants. The effect of aluminum sulfate, ferrous sulfate, and stannous chloride mordants on colorimetric and fastness properties of wool fibers was investigated. Juglone was identified as the main coloring component in walnut bark extract by UV visible and FTIR spectroscopic techniques. The results showed that pretreatment with metallic mordants substantially improved the colorimetric and fastness properties of wool fibers dyed with walnut bark extract. Ferrous sulfate and stannous chloride mordanted wool fibers shows best results than potassium aluminum sulfate mordanted and unmordanted wool fibers. This is ascribed due to strong chelating power of ferrous sulfate and stannous chloride mordants
Role and immunomodulatory profile of histamine receptors by H1 and H2 antagonists
The present study was designed to delineate the immunomodulatory role of histamine receptors (H1- and H2-) on induction of antibody response to sheep red blood cells (SRBC), as well as the antibody generation profile, in rabbit system, systemically. The rabbits in two groups received pheniramine (H1-receptor antagonist) and ranitidine (H2-receptor antagonist), respectively, via intramuscular route and were immunized with SRBC intravenously to evaluate suppression or enhancement of antibody responses in sem. A third, control group, received vehicle and were immunized in a similar manner. Histamine released from effector cells (mast cells and basophils) _in vivo_ during inflammatory reactions could influence a detectable antibody response to SRBC as early as day 7-postimmunization (post-I), which lasted until day 28- post-I. Pheniramine-treated rabbits had significantly (*Pa ≤ 0.05 and **Pa ≤ 0.01) more suppressed total serum antibody (IgM + IgG) to SRBC as compared to ranitidine-treated ad cotrol rabbits, while ranitidine-treated rabbits showed different pattern (suppressed or enhanced) during the whole study period. Ranitidine suppressed total antibody level at days 7- and 14- post-I, and enhanced at days 21- and 28- post-I. IgM suppression at day 7- and enhancement at days 14-, 21- and 28- post-I, while IgG suppression during whole study period, as compared to control group was significant (*Pa ≤ 0.05 and **Pa ≤ 0.01) as assessed by direct hemagglutination assay* ad whole SBC-ELISA method**. Here we report that histamine receptor type 2 (H2R)-antagonists have a dominant role on immunosuppression and in immunoregulation of humoral immune responses. Histamine receptor type 2 (H2R)-antagonists are mainly involved in B cell differentiation and proliferation over histamine receptor type 1 (H1R)-antagonists
An eco-friendly dyeing of woolen yarn by Terminalia chebula extract with evaluations of kinetic and adsorption characteristics
In the present study Terminalia chebula was used as an eco-friendly natural colorant for sustainable textile coloration of woolen yarn with primary emphasis on thermodynamic and kinetic adsorption aspects of dyeing processes. Polyphenols and ellagitannins are the main coloring components of the dye extract. Assessment of the effect of pH on dye adsorption showed an increase in adsorption capacity with decreasing pH. Effect of temperature on dye adsorption showed 80 °C as optimum temperature for wool dyeing with T. chebula dye extract. Two kinetic equations, namely pseudo first-order and pseudo second-order equations, were employed to investigate the adsorption rates. Pseudo second-order model provided the best fit (R2 = 0.9908) to the experimental data. The equilibrium adsorption data were fitted by Freundlich and Langmuir isotherm models. The adsorption behavior accorded well (R2 = 0.9937) with Langmuir isotherm model. Variety of eco-friendly and sustainable shades were developed in combination with small amount of metallic mordants and assessed in terms of colorimetric (CIEL∗a∗b∗ and K/S) properties measured using spectrophotometer under D65 illuminant (10° standard observer). The fastness properties of dyed woolen yarn against light, washing, dry and wet rubbing were also evaluated
