A NOVEL DESIGN OF FLOWER TYING MACHINE

 A prototype model of automated flower string machine is proposed to knot the flowers. In India’s rich culture flower garlands play a vital role. They are used for decorations and adorations of Gods, men and women. Garlanding of flower is a monotonous and time- consuming job. The flower string machine is conceptualized based on the working principle of sewing machine and added multiple kinematic mechanisms to drive the flower feeding and stringing. The flowers will be placed on the conveyor belt and based on process control technique; an innovative knotting mechanism will be used to string the flowers. It is also a customized machine for armless and loss of fingers community. Flower tying machine ensures perfect garlanding in an affordable cost. By this technique, the manual work can be reduced and flower vendors can utilize their time effectively

On a Ramanujan Quantity

Abstract: In this paper, We study the several modular equations of Ramanujan Quantities R(1, 2, 4; q) (established by Nikos Bagis) and R(1, 2, 4; q n ) for n = 4, 6, 8, 9, 10, 11, 13, 14, 15, 17, 19, 23 and 25

Synthesis, characterization, thermal, anticancer and dna binding properties of co(ii), ni(ii), cu(ii), cd(ii) and zn(ii) complexes with schiff base

A series of metal complexes of Co(II), Ni(II), Cu(II), Cd(II) and Zn(II) were synthesized with newly prepared ligand. This ligand was prepared by the condensation of hydrazide with 2-chloro benzaldehyde. The resulting complexes were characterized by elemental analyses, spectroscopic data i.e. IR, UV, mass, molar electric conductibility as well as magnetic measurements. The complexes were square planar and octahedral in nature. Thermal studies of the complexes were also reported. Metal complexes exhibited DNA binding, cleavage and anticancer activities which were significantly better than the ligand

Badanie właściwości komfortu termicznego różnych rodzajów dzianin poliestrowych

This research focused on the thermal comfort behaviour of polyester with respect to the type of yarn (spun, micro denier, continuous filament and hollow), linear density of the yarn (111 and 166 dtex), and the loop length of knitted fabric (0.25, 0.27 and 0.29 cm).The air permeability of continuous filament yarn fabric and micro denier yarn knitted fabrics was noted to be higher than that of spun yarn knitted fabrics. 111 dtex micro denier yarn fabric has the highest air permeability and 111 dtex spun yarn fabric the lowest air permeability value among all the other fabric samples. Comparatively, coarser spun yarn fabric has lower air permeability characteristics than finer microdenier fabric.The water permeability of the fabric shows a significant difference between the spun yarn, continuous filament yarn and Micro denier yarn knitted fabrics and between the linear density of the yarn. The water vapour permeability of spun yarn of 166 dtex single jersey fabric is higher, while the water vapour permeability of continuous filament yarn fabric of 166 dtex is lower. The thermal conductivity value is high for continuous filament polyester fabric of 100 D and low for microdenier polyester fabric of 166 dtex. Based on the statistical analysis, it is clearly shown that there are significant differences between the three different polyester yarn fabrics of two different denier of the same fabric. Furthermore, the count and different polyester yarn affect the comfort properties of single jersey fabrics.Badania koncentrowały się na zachowaniu komfortu cieplnego poliestru w odniesieniu do rodzaju przędzy, gęstości liniowej przędzy (111 dtex i 166 dtex) oraz długości pętelki dzianiny (0,25 cm, 0,27 cm oraz 0,29 cm). Zbadano właściwości wytworzonych dzianin takie jak: przepuszczalność powietrza, wody, pary wodnej oraz przewodność cieplną, a wyniki poddano analizie statystycznej
