Green and Sustainable Method to Improve Fixation of a Natural Functional Dye onto Cotton Fabric Using Cationic Dye-Fixing Agent/D5 Microemulsion
No full textThe low fixation rate and colorfastness of natural dyes limit their practical application in modern textile coloration. Further, hazardous mordants are used in conventional natural dyeing to achieve better fixation and colorfastness. Herein, a green, sustainable, and environmental benign fixation process of natural dye was developed using a non-aqueous medium in the absence of mordants to enhance the fixation rate and colorfastness of the dyed fabric. The process was executed by the treatment of the cacao husk extracts/decamethylcyclopentasiloxane (D5) dyed cotton fabric with a cationic dye-fixation agent (CFA)/D5 microemulsion. The conditions of optimal dye fixation process including water content, fixation time, fixation temperature, and CFA mass were determined by using L-9 orthogonal array. Significant improvements in the fixation rate (95.03%) and color strength (15.26) were found after CFA treatment under the optimal conditions. Although the light fastness of the CFA-treated dyed fabrics was poor, the colorfastness to rubbing and washing were remarkable. The cacao husk extracts natural functional dye significantly enhanced the UV resistance of the dyed fabric, and the CFA treatment improved the crease recovery characteristic of the dyed fabric. The stiffness of the fabric decreased slightly after dyeing and CFA treatment. Consequently, this study paved the way for the sustainable and green dyeing process
Current-voltage characteristics of Bi<sub>2</sub>Sr<sub>2</sub>Ca<sub>2</sub>Cu<sub>3</sub>O<sub>10</sub>+x/Ag multifiliamentary tapes in zero applied magnetic field
No full textCurrent - voltage characteristics of multifilamentary Bi2Sr2Ca2Cu3O10/Ag tapes (short samples) produced by the 'powder in tube' technique were measured at different temperatures close to the mean-field critical temperature, and in zero applied magnetic field. After performing the required corrections due to the current flowing in the silver matrix, the I - V curves were interpreted in terms of current-induced unbinding of the thermally created vortex - antivortex pairs. Two possible mechanisms for appearance of a finite critical current in zero applied magnetic field are discussed: the Jensen - Minnhagen quasi-two-dimensional (2D) approach, that takes into account the interlayer Josephson coupling, and a model of size limitation of vortex fluctuations. From our analysis, it seems that the latter model is more suitable for this kind of superconducting material, due probably to an accentuated intrinsic anisotropy
Efektivitas Program Sarapan Pagi terhadap Peningkatan Pemahaman Belajar Anak di MIU Riyadlul Qori’in Jember
No full textPenelitian ini bertujuan untuk mengkaji efektivitas program sarapan pagi yang diterapkan di MIU Riyadlul Qori’in Jember dalam meningkatkan pemahaman belajar siswa. Pendekatan yang digunakan adalah deskriptif kualitatif dengan subjek penelitian sebanyak 45 siswa kelas III, IV, dan V. Data dikumpulkan melalui observasi, wawancara, dan dokumentasi, serta dianalisis menggunakan teknik reduksi data, penyajian data, dan penarikan kesimpulan dengan validasi triangulasi sumber. Hasil penelitian menunjukkan bahwa program sarapan pagi di sekolah berkontribusi positif terhadap peningkatan konsentrasi, keaktifan, dan pemahaman materi pelajaran siswa. Selain itu, keterlibatan orang tua dan edukasi gizi turut mendukung keberhasilan program ini. Dengan demikian, program sarapan pagi terbukti efektif dalam menunjang proses belajar dan prestasi akademik siswa di tingkat sekolah dasar
Coexistence of Endometriosis and Thyroid Autoimmunity in Infertile Women: Impact on in vitro Fertilization and Reproductive Outcomes
No full textObjectives: The objective of the study was to evaluate the prevalence and impact of impaired thyroid-stimulating hormone (TSH) levels on the reproductive outcomes of in vitro fertilization patients diagnosed with endometriosis and compared to controls without endometriosis. Design: This is a retrospective cohort study on prospectively collected data. Setting: The study was conducted at tertiary care university hospital. Participants: Participants were infertile women with histopathological diagnosis of endometriosis. Methods: For 12 months (January 2018 to January 2019), women were deemed suitable and subsequently divided according to serum TSH levels above or below 2.5 mIU/L and compared to patients without endometriosis. Needed sample size was at least 41 patients for each cohort of women. Co-primary outcomes were the live birth rate (LBR), clinical pregnancy rate (CPR), and pregnancy loss rate (PLR). Results: Overall, 226 women (45 with endometriosis and 181 controls without endometriosis) were included. Diagnoses of Hashimoto thyroiditis were significantly more frequent in women with rather than without endometriosis (14/45 [31.1%] vs. 27/181 [14.9%]; p = 0.012). Similarly, in women with endometriosis, Hashimoto diagnosis rates were higher with TSH ≤2.5 mIU/L compared to TSH <2.5 mIU/L (9/ 15 [60%] vs.5/30 [16.6%]; p = 0.001) so were the Hashimoto diagnosis rates in control group (women without endometriosis) with TSH ≤2.5 mIU/L compared to TSH <2.5 mIU/L (17/48 [35.4%] vs. 10/133 [7.5%], respectively; p = 0.001). Effect size analysis confirmed an increased risk of Hashimoto thyroiditis in women with endometriosis and TSH ≤2.5 mIU/ L compared to women with endometriosis and TSH <2.5 mIU/L (risk ratio [RR] 3.60 [95% CI 1.46-8.86]) and in women with endometriosis and TSH ≤2.5 mIU/L compared to non-endometriotic euthyroid patients (RR 7.98 [95% CI 3.86-16.48]). Dysmenorrhea risk was higher in endometriotic euthyroid women compared to euthyroid patients with no endometriosis (RR 1.87 [95% CI 1.21-2.87]). The risk was still increased in euthyroid women with endometriosis relative to dysthyroid women with no endometriosis (RR 1.97 [95% CI 1.11-3.50]). There were no significant differences between the four groups for CPR, LBR, PLR and retrieved oocytes, immature oocytes, degenerated and unfertilized oocytes, cultured blastocysts, embryos and transferred embryos. Limitations: Limitations of the study were retrospective design, limited sample size, and use of different ovarian stimulation protocol. Conclusions: Thyroid autoimmunity seems more common in women with endometriosis and TSH over 2.5 mIU/L. However, there was no significant impact on in vitro fertilization and reproductive outcomes related to the coexistence of endometriosis, Hashimoto disease, and higher TSH levels. Due to limitations of the study, additional evidence is required to validate the abovementioned findings
Combined Zidovudine and Interferon-α 2a Therapy in Children with Acquired Immune Deficiency Syndrome
No full textA study was carried out in five children with acquired immune deficiency syndrome to assess the effect of combined zidovudine/interferon-alpha 2a therapy with that of zidovudine given alone on immunological profiles and plasma zidovudine concentrations. Immunoglobulins A, G and M, total and absolute CD4 lymphocyte counts, and p24 antigen concentrations did not differ significantly when children were treated with 300 mg/m2 zidovudine given orally once every 12 h, or with 150 mg/m2 zidovudine plus 1.5 or 3 MIU interferon-alpha 2a given intramuscularly three times weekly. Peak plasma zidovudine concentrations were significantly (P less than 0.05) lower when combined treatment with 150 mg/m2 zidovudine/1.5 MIU interferon-alpha 2a was administered compared with 300 mg/m2 zidovudine alone, or combined 150 mg/m2 zidovudine/3 MIU interferon-alpha 2a. The results suggest that combination zidovudine/interferon-alpha 2a therapy may be more efficacious than zidovudine alone and that the normal zidovudine dose may be reduced if interferon-alpha 2a is given in addition, thus reducing the side-effects associated with zidovudine
