Objective: The present study highlights the development of a method to synthesize copper nanoparticles (CuNPs).Methods: CuNPs were developed using 0.01 M copper penta sulfate and 0.11 M of ascorbic acid (AA) and 0.03 M of cetyl trimethyl ammonium bromide solution. The synthesized CuNPs were differentiated through filtration and washed by water (deionized). CuNPs were kept in dialysis bag 70 KD in a 250 mL glass beaker along with distilled water. The assembly was kept on a magnetic stirrer for 24 h at 500 rpm. Then, the dialysis bag containing CuNPs solution was filtered by a filter assembly with 0.2 μm nylon filter. The filtered CuNPs were spray dried with the help of spray drier.Results: The prepared CuNPs were found to be 440 nm with zeta potential of −10 mV and polydispersity index 0.314.Conclusion: The investigation deciphers the promising and material technique to synthesis of CuNPs by methods for synthetic reduction utilizing strategy using AA (0.2 M) and sodium hydroxide (1 M), and Syloid 244FP.

<p>Utilization of molasses as basic material for producing bioethanol becomes one of the promising efforts to fulfill the demand of fuel and diminish the dependence upon fossil fuel that its availability is increasingly rare. However, ethanol produced from fermentation of molasses has low purity. The purity could be increased by using dehydration method and zeolite activated by NaOH and alum as alumina source. The research is aimed to know the dehydration process of bioethanol use NaOH-activated zeolite at various concentration and zeolite weight on the purification of bioethanol. In this research, the experiments could be categorized into 4 groups, they are activation of zeolite, fermentation, distillation, and dehydration process. Activation of natural zeolite performed by entering of sized 120-150 mesh zeolite powder was added to glass beaker that contains  NaOH aqueous solution and followed by adding alum which took place at 80 ˚C for 8 hours and the final product calcinated at 600 ˚ C for 2 hour. Fermentation process was managed for 6 days and pH 5. Furthermore, bioethanol was separated by distillation method at 78,5 - 85 ˚C and followed by molecular sieve dehydration using zeolite activated by NaOH solution in variation of zeolite weight (30, 40 and 50 %) and NaOH concentration (1, 2, 3 dan 4 M). The amount of bioethanol was measured by gas chromatography method. Bioethanol concentration as fermentation product is 29,8 %. The result revealed that dehydration with 30% w.t zeolite activated by 2 M NaOH solution had the best activity in bioethanol purification with amount of bioethanol is 53,76 %, Increased Levels of Bioethanol (ILB) value is 80,39 % and Adsorption Capacity of Zeolite (ACZ) is 399,31 %.</p><p>Keywords: bioethanol, concentration of NaOH, dehydration, molasses, molecular sieve, weight of zeolite</p>

bonded magnet is composite magnet material made by mixing magnetic powder with non-magnetic binder. The process in manufacturing bonded magnet NdFeB made by mixing powder of neodymium iron boron (NdFeB) commercial type MQP-B with a polyvinyl butyral powder using a glass beaker. The comparisons of variation in composing NdFeB magnets powders with a binder of PVB (% weight) are 98:2, 96:4, 94:6 and 93:7 of 8 grams from total mass of the sample. After mixing the powder, it is molded by using a compression molding method with 8 tons pressure for 20 minutes at curing temperature 1600C. The molded samples are conducted by characterizing the physical properties which include measurement of density, microstructure analysis using SEM-EDX and magnetic properties which include measurement of the magnetic field strength using a Gaussmeter and hysteresis curve using VSM. The result of the study shows that the addition of and binder PVB in bonded magnet NdFeB causes a decrease in the density and magnetic field strength. The best result of density and magnetic field in the manufacture of bonded magnets is obtained by the addition of 2 % binder of 5.66 g/cm3 and strong magnetic field of 1862.4 G. the score of Mr = 72.86 emu/g, Ms = 103 emu/gram, Hc = 8.490 KOe and BHmax = 5.1 MGOe was obtained on the addition of PVB 2 %.

Intestinal worm disease is one of the parasitic diseases that still infect humans, especially children. School-age children, especially elementary school children, are generally less familiar with self-sanitation. Most diseases of the worms are transmitted through dirty hands. Community service at SD Inpres Pampang 1 was done to educate students about the implementation of good self-sanitation and precisely how to wash hands based on WHO standards. The tools used in this study were chalkboard, camera, microscope, reaction tube, glass object, glass cover, container/basin, stirrer rod, glass beaker, tube rack, petri dish, nail clippers, and pens. The materials used in this training were hand nails students SD Inpres Pampang 1, water, and salt. Based on the results and evaluation, it concludes 1) Worm infections can occur when there are worm eggs attached to the nails that are swallowed in with food. 2)  improving participants ' understanding and knowledge of self-sanitation for everyday life, especially the right-hand washing way.

Freshly harvested triticale seeds are usually dormant, making the immediate evaluation of the physiological potential of seed lots difficult. We evaluated different triphenyl tetrazolium chloride (TTC) test methods for rapidly determining the viability of four seed lots of x.Triticosecale Wittmack cultivar IPR111. The test variables were: Preconditioning, (i) placing whole seeds between moistened paper towels or (ii) directly soaking the seeds in water, both procedures being conducted at 20 ºC for 18 hours; Post-conditioning seed preparation, (i) longitudinal bisection of the seed through the embryo with one half being stained and the other discarded or (ii) longitudinal bisection with both halves being stained; Staining for three and four hours, in the dark, with 0.1%, 0.5% or 1.0% (w/v) TTC according to the preconditioning method described above, (i) both halves of each seed were placed on filter paper moistened with TTC and maintained at 40 ºC or (ii) one half of each seed was immersed in 5 mL of TTC solution in a 100 mL glass beaker at 30 ºC. The best results were obtained by preconditioning seeds between moistened paper towels at 20 ºC for 18 hours and staining on filter paper with 1.0% (w/v) TTC for three hours at 40 ºC.

Cultural Developments

ít‘Domesticating’ as a process shows how a larger cultural shift—in this case, that of the Counter-Reformation—became something quotidian, everyday, accessible, and realized on the ground. It was a process by which new cultural developments became part of a broader mentalité. The focus of this chapter is to examine the concrete ways in which Catholic culture was domesticated in burgher homes over the seventeenth century. It examines how Counter-Reformation styles and themes permeated domestic objects, how Counter-Reformation images were newly integrated into domestic scenes, and how new materials contributed to the diversification of Catholic material culture at the end of the seventeenth century in a constant negotiation between ‘official’ and lay demands. From the material evidence—rose motifs, a cold-enamel painted glass beaker, and agnus dei made from a range of materials—emerges a fascinating coalescence of old and new forms of devotion that exemplifies the interplay between local and universal. It represents diversification and elaboration in the formation of a new Baroque Catholic culture in the home that was driven as much by the laity as by the Church in the second half of the seventeenth century.
