An Experimental Analysis of Turning Operation in EN 31ALLOY
No full textTurning is a form of machining process which is used to create a cylindrical part by cutting away unwanted materials. Today the most common type of automation is computer numerical control, better known as CNC. Components such as axles, shafts can be manufactured by turning process. In that manufacturing unit mainly focuses on high quality with increased production rate and profit level of the firm and so it's important to determine the optimal machining parameters such as speed, feed and depth of cut. This works deals with the selecting the optimal parameters that plays a critical role in increasing the productivity with desired product quality at minimum cost and reduced lead time. The experiments were conducted with Taguchi's L 9 mixed orthogonal array. Coated insert was used to machine the EN 31 alloy steel work pieces on computer numerical controlled CNC lathe. The optical parameters were found using Taguchi's approach individually for minimum surface roughness and maximum material removal rate MRR and were compared with the results obtained from Grey relation analysis.

No full textNot AvailableTomato (Solanum lycopersicum L.) fruits of nine popular varieties in India were analysed for change in the
levels of different nutrients (P, K, Fe, Zn, B, Cu, Mg, Ca and Mn) during the period of their postharvest ripening
(fruits harvested at green mature stage and stored at 25 ± 1 C). This work is in continuation of our previous
and related work wherein similar studies were done on the tomato fruits undergoing ripening while attached to the plant (Ramesh in 1–15, 2020). Here in this study, nutrients were estimated in the outer pericarp of tomato fruits at the time of their harvest (at green mature stage) and during the storage period at 5, 10 and 14 days after harvest (DAH). Under above said storage conditions, ripening behaviour of tomato fruits of different varieties was also determined by ripening index (RI %) at 3, 5, 8, 10 and 14 DAH. The results on nutrients showed net increase in P, K, Fe, Zn, B and Cu with static levels for Mg, Ca, and Mn at 14 DAH in comparison to their levels at green mature stage. The increase is explained in view of remobilization of nutrients from other parts of the fruit to the outer pericarp. While, internal mobilization of nutrients within the fruit might have helped in maintaining the static level of nutrients. Correlation analyses revealed that lower content of K and Ca along with higher content of B and Cu can impart slow ripening to tomato fruits. Comparison between plant-attached
(our earlier study) and plant-detached tomato fruits (this study) indicated that in contrast to the fruits at green
mature stage there is net increase in Zn, B, Cu, Mg, Ca and Mn in the outer pericarp of plant-detached ripened fruits. This was due to the internal mobilization of nutrients within the fruits towards the outer pericarp and absence of any remobilization or back flow of nutrients away from the fruits as the fruits were off the plant.Not Availabl
Dynamics of mineral nutrients in tomato (Solanum lycopersicum L.) fruits during ripening: part II?off the plant

Embedding Approximately Low-Dimensional l_2^2 Metrics into l_1
Full text linkGoemans showed that any n points x_1,..., x_n in d-dimensions satisfying l_2^2 triangle inequalities can be embedded into l_{1}, with worst-case distortion at most sqrt{d}. We consider an extension of this theorem to the case when the points are approximately low-dimensional as opposed to exactly low-dimensional, and prove the following analogous theorem, albeit with average distortion guarantees: There exists an l_{2}^{2}-to-l_{1} embedding with average distortion at most the stable rank, sr(M), of the matrix M consisting of columns {x_i-x_j}_{i<j}. Average distortion embedding suffices for applications such as the SPARSEST CUT problem. Our embedding gives an approximation algorithm for the SPARSEST CUT problem on low threshold-rank graphs, where earlier work was inspired by Lasserre SDP hierarchy, and improves on a previous result of the first and third author [Deshpande and Venkat, in Proc. 17th APPROX, 2014]. Our ideas give a new perspective on l_{2}^{2} metric, an alternate proof of Goemans' theorem, and a simpler proof for average distortion sqrt{d}
Does strict employment protection discourage job creation? Evidence from Croatia
Full text linkEmployment protection legislation in Croatia is among the most strict in Europe. Firing is difficult and costly, and flexible forms of employment are limited. Is this apparent rigidity reflected-as one would expect based on standard economic theory-in low labor market dynamics? Is job creation low and hiring limited? Is the job security of insiders achieved at the cost of outsiders not being able to enter thelabor market? The author attempts to answer these questions by examining job flows. If the employment protection legislation is binding, then job and worker turnover should be low. He shows that this is indeed the case. Hiring is limited and the average job tenure is very long in Croatia. Job destruction is low, however job creation is still lower. The result is accumulation of unemployment, in large part due to new labor market entrants not being able to find a job. The high degree of job protection also seems to strengthen the bargaining position of insiders and results in relatively high wages. So, wages in Croatia are higher than among its competitors, even after adjusting for productivity. These high labor costs are likely to contribute to limited job creation in existing firms, but also are likely to discourage the entry of-and thus job creation in-new firms. The author presents evidence that firm growth has been indeed limited in Croatia, contributing to the low employment level. The author examines other potential causes of high unemployment in Croatia (the unemployment benefit system, labor taxation, the wage structure, and skill and spatial mismatches). He argues that they do not play a substantial part in accounting for poor labor market outcomes in Croatia. The author concludes that the stringent employment protection legislation is the key labor market institution behind low job creation and high unemployment. Based on this he recommends specific measures aimed at liberalizing the labor market to foster job creation and employment.Labor Management and Relations,Labor Policies,Labor Markets,Environmental Economics&Policies,Trade Finance and Investment,Labor Markets,Labor Management and Relations,Labor Standards,Banks&Banking Reform,Environmental Economics&Policies
Seawater heat recovery by the utilisation of phase change heat of freezing
Full text linkWith the Paris agreement calling to limit global warming to 2°C below pre-industrial levels, with further efforts to ensure it stays below 1.5°C, the Finnish government passed the Laki hiilen energiakäytön kieltämisestä (416/2019), i.e., Act of Prohibition of Coal Energy, which stipulates that the use of coal as a fuel for heat/electricity production to be banned from 1 May 2029. This affects Helsinki’s energy industry and a key concern to this work is the Salmisaari Combined Heat and Power plant, which is set to be decommissioned. This plant currently generates heat and electricity by using wood pellets and coal to cater to around 25-45% of the District Heating consumption of the city of Helsinki.
To compensate for this decommissioning, there arises a need for more heat production, around 300-500MW of capacity. One alternative is the heat recovery of seawater by utilising the phase change heat of freezing. The present project investigates a technical feasibility study of a system to generate ice slurry, which is then used to extract heat from seawater at ~0°C via a heat pump. The competitiveness of an ice-slurry based system to state-of-the-art water or ice-based storage is analysed as well. The proposed system is then modelled in Aspen Plus, and the pressure drop characteristics of the generated ice slurry are studied. Finally, a sensitivity analysis of the pressure ratio of the compressor on the performance of the system is studied.
Based on prior works, level of commercialisation and technical feasibility, it was found that a vacuum ice generation method, in combination with heat pumps, is a viable solution to cater to the district heating demand of the city. Further, it is concluded that the pressure drop occurring during transport of the ice slurry is quite minimal – less than 0.5% of the total power consumed whilst producing 300MW of district heat. The COP of the system varies between 2.6-2.8 depending on the pressure ratio of the compressor and thus is energy efficient. Overall, the proposed solution seems to be promising and with further socio-techno-economic analysis, this could be the potential alternative to bridge the deficit
