Contribution of rock glacier discharge to late summer and fall streamflow in the Uinta Mountains, Utah, USA
Authors: Munroe Jeffrey S. , Handwerger Alexander L.
Published: January 2023

Abstract. Water draining from rock glaciers in the Uinta Mountains of Utah
(USA) was analyzed and compared with samples of groundwater and water from
the primary stream in a representative 5000 ha drainage. Rock glacier water resembles snowmelt in the early summer but evolves to higher values of d-excess and greatly elevated Ca and Mg content as the melt season progresses. This pattern is consistent with models describing a transition from snowmelt to melting of seasonal ice to melting of perennial ice in the rock glacier interior in late summer and fall. Water derived from this internal ice appears to have been the source of ∼25 % of the streamflow in this study area during September of 2021. This result emphasizes the significant role that rock glaciers can play in the hydrology of high-elevation watersheds, particularly in summers following a winter with below-average snowpack.
Seasonal cycle of sea surface temperature in the tropical Angolan Upwelling System
Authors: Körner Mareike , Brandt Peter , Dengler Marcus
Published: January 2023

Abstract. The Angolan shelf system represents a highly productive
ecosystem. Throughout the year the sea surface is cooler near the coast than
further offshore. The lowest sea surface temperature (SST), strongest
cross-shore temperature gradient, and maximum productivity occur in austral
winter when seasonally prevailing upwelling-favourable winds are weakest.
Here, we investigate the seasonal mixed layer heat budget to identify
atmospheric and oceanic causes for heat content variability. By using
different satellite and in situ data, we derive monthly estimates of surface
heat fluxes, mean horizontal advection, and local heat content change. We
calculate the heat budgets for the near-coastal and offshore regions
separately to explore processes that lead to the observed SST differences.
The results show that the net surface heat flux warms the coastal ocean
stronger than further offshore, thus acting to damp spatial SST differences.
Mean horizontal heat advection is dominated by meridional advection of warm
water along the Angolan coast. However, its contribution to the heat budget
is small. Ocean turbulence data suggest that the heat flux, due to turbulent
mixing across the base of the mixed layer, is an important cooling term.
This turbulent cooling, being strongest in shallow shelf regions, is capable
of explaining the observed negative cross-shore temperature gradient. The
residuum of the mixed layer heat budget and uncertainties of budget terms
are discussed.

Authors: Chhillar Ajay , Singh Rajender
Published: January 2023

Plastic deformation of metal parts has been a matter of concern for investigators in academia, industry and research institutions all over the world. Literature reveals that earlier researchers have applied efforts for predicting plastic deformations using mesh based approach. A truly meshless formulation for rigid plastic analysis of metal parts has been developed in the present study for both plane stress and plane strain cases. In the present formulation, the governing equations are obtained for different set of scattered nodes over the problem domain and the integral equation for rigid plastic behavior is obtained through weak form over a local sub-domain. The meshless solution functions are obtained for different set of scattered nodes through moving least square technique. Essential boundary conditions are enforced through Penalty approach. The rigid plastic constitutive relationships incorporate only small deformation. Material constitutive relationship include Von-Mises yield criterion with rate independent associative flow theory. The solution algorithm for rigid plastic analysis of metal parts using meshless approach is discussed in the present work. Numerical results have been computed through two test functions using both linear and quadratic basis function which shows that presented formulation is accurate and robust for carrying out the rigid plastic analysis of metal parts.

Authors: Misra R. S.
Published: January 2023

This paper describes thermal modelling of vapour compression refrigeration system using (ii) eco-friendly refrigerants in primary circuit with nano particles mixed with R718 in secondary evaporator circuit. This model takes care of the secondary nanoparticles mixed in the fluids as input conditions as geometric characteristics of the system such as size of nanoparticles and the compressor speed to predict the secondary fluids output temperatures, the operating pressures, the compressor power consumption and the system overall energy performance. Such design analysis is conveniently useful to compare the thermal performance of different nanoparticles (Cu, Al2O3, TiO2) based nanofluid as a secondary fluid in a vapour compression refrigeration system. The influence of input variables on the irreversibilities in terms of exergy destruction ratio of the system is presented. Such a model can also be used to design various components viz. evaporator, compressor, condenser and throttle valve for vapour compression refrigeration systems for any desired cooling capacity. This model takes care of use of nanofluids as a secondary fluid in vapour compression refrigeration systems and simulate the non-linear equations of the system. It was observed that for the same geometric characteristics of the system, first and second law performance improved from 8% to 17% by using eco-friendly refrigerants in the primary circuit and nanoparticles mixed with water as a secondary fluid in VCS .and first and second law performance improved from 8% to 32% by mixing nano particles in the eco-friendly refrigerants in the primary circuit

Published: January 2023

In spite of many advantages behind the dependence on the photovoltaic (PV) systems butthe efficiency level of the PV module still not satisfying. The fuel of the PV modules is the amount of sun light absorbedby the module and that depends on many factors such as front surface reflectivity, solar beam incidence angle and the most important is the transmissivity of the front surface. Soiling and dust accumulation reduce the transmissivity. This article presents a review for the studies about the impact of dust accumulation on solar PV module performance and a discussion for some solutions or cleaning techniques implemented in the previous studies. Also in this work, a new method is introduced to reduce the soiling. The method can briefly described as a moving cover with a cotton cloth attached firmly to the backside of the cover. At sunset, the module should be covered and the cloth wipes down part of the dust and the opposite happens at the sunrise. The results showed that a 9.22% gain in power produced by covered module than the uncovered module. Also, the covered module output was very close to the module after it was cleaned.

Authors: Singh Jeewan , Singh Harvinder , Goyal Aneesh
Published: January 2023

Metal working fluids (MWFs) are one of the types of lubricants, which are extensively used in machining operations. Most of the MWFs are mineral oil based fluids. Due to their advantages, the consumption of MWFs is increasing in machining industry. Mineral, synthetic and semi-synthetic MWFs involve in the ecological cycle with air, soil and water and their toxicity effects damages the ecosystem. Vegetable oil lubricants are potential substitutes for mineral oil not only because they are renewable raw materials but also because they are biodegradable and non-toxic. Currently, there is a wide-scale evaluation of the use of metal working fluids (MWFs) in machining. Industries are looking for ways to reduce the amount of lubricants in metal removing operations due to the ecological and economical aspects. By implementing near-dry machining or a minimal quantity of lubrication (MQL), MWFs consumption can be reduced. The MQL technique involves the application of a small quantity of lubricant dispensed to the tool–work piece interface by compressed air flow. This paper gives a review on the mechanical performance of minimum quantity lubrication compared to completely dry and flood lubrication for various machining operations.
Smart Materials: New Trend in Structural Engineering
Authors: Singh Harvinder , Singh Ramandeep
Published: January 2023

Smart materials, which have the functions of actuator, sensor, self-healing and so forth, are expected to be used not only as advanced functional materials but also as key materials to provide structures with smart functions. Smart systems sense changes in structure variations in vibration, noise or temperature, for example process the information and then respond appropriately to automatically correct possibly detrimental problems. They tell the structure to alter its properties to prevent damage, optimize performance, correct malfunctions or alert users to a needed repair.
Smart materials technology applies to a huge range of products including buildings, bridges, computers, cameras, aircraft, even skis. Think about the way in which excessive vibration in a machine on the shop floor may result in overheating, or parts that don’t meet the manufacturer’s specifications. Then, imagine the problems that could occur if a similar situation happened on an aircraft and you begin to understand the scope and value of smart material applications.
The best way to understand the smart material concept is to look at its uses. Smart materials may work completely on their own or as part of a larger smart system. For example, doctors may use shape memory alloy staples used to set broken bones. In this case, the material works as both a sensor and an actuator as the patient’s body heat activate the staple to close and thereby clamp the break together. This report deals with the available smart materials, their properties and some of their areas of application and future prospects.”

Authors: Rahman Atikur , Mahajan Chitrashi
Published: January 2023

Electroless Co(x = 0.04, 0.03, 0.02) and Al(y = 0.01, 0.02, 0.03) doped ZnO nanostructured thin films have been deposited on soda lime glass in the present work. The wet deposited films are dried in air and subsequently annealed at 500oC for 2 hr in a muffle furnace in air environment. The film deposited samples are characterized by SEM, XRD, Superconducting quantum interference device (SQUID) magnetometer and UV visible spectrophotometer. Microstructure of the Co and Al doped ZnO film is strongly affected by different doping concentration into ZnO matrix. X-ray diffraction analysis confirms the absence of metallic Co or Al clusters or any other phase different from wurtzite type ZnO. The field dependence of magnetization (M-H) curve of different concentration of Co and Al doped ZnO films measured at room temperature exhibits the clear ferromagnetism with saturation magnetization (Ms) and coercive field (Hc) of the order of 3.843 to 4.813 10-3(emu) and 400.389 to 436.769(Oe) respectively. It is found that ferromagnetism increased correspondingly with Co concentration. The relevant ferromagnetism mechanisms at room temperature in Co and Al doped ZnO films are discussed.

Published: January 2023

Modal analysis can be a powerful tool to assist in the identification and elimination of fatigue problems. The most obvious use of modal analysis is in determining the natural frequencies of the turbine blades. Knowledge of these frequencies can be very useful in avoiding excessive excitations and thereby reducing the risk of fatigue failure. A less obvious application of modal analysis is in the validation of computer generated models of the turbine blades. These models can be very useful to investigate turbine and turbine blade properties under running conditions. Finite element models can be used to predict the influence of design changes on the stresses and strains acting on the turbine blade under running conditions.

Published: January 2023

Medical Tourism is not a new phenomenon, but it is taking on a completely different persona to what was earlier envisaged. Today, with the globalization of information and the empowerment of the consumer, medical tourism involves individuals acting as a consumer, making their own decisions regarding their health needs, deciphering how they can best be treated, and then finding the most appropriate provider.
Paper intends to deal with how countries across the world are competing on quality and price, how they are getting more competitive and developing their own health tourism strategy. Today, medical tourism is no longer about cheaper procedures and holiday trips. Paper would also correlate the impact of quality of doctors and technology, and care models that countries are pursuing on rise of health tourism in respective countries.
The central pillar of the paper would revolve around how disruption caused in the aviation industry via low cost airlines and social media has impacted the flow of patients from developed nations to other regions making medical tourism a considerable norm rather than something reserved only for the affluent.
Paper would also throw a brief light on alternative medicine such as Ayurveda, acupuncture and homeopathy that are gaining popularity among medical tourists.

These can be check only after cross section cut and those parts will be rejected, so we have to find one more factor which can be validate process and insure quality with easy method. In GAIM, Part weight is very important criteria and now we need to established relation with part wall thickness. The GAIM study, trials, result, analysis and our experiment provides part weight have proportional related with part wall thickness.

CNC Vertical Milling Machining is a widely accepted material removal process used to manufacture components with complicated shapes and profiles. During the face milling process, the material is removed by the 10 mm Dia tool. The effects of various parameters of milling process like spindle speed, depth of cut, feed rate have been investigated to reveal their Impact on surface finish using Taguchi Methodology. Experimental plan is performed by a Standard Orthogonal Array. The results of analysis of variance (ANOVA) indicate that the feed Rate is most influencing factor for modeling surface finish. The graph of S-N Ratio indicates the optimal setting of the machining parameter which gives the optimum value of surface finish. The optimal set of process parameters has also been predicted to maximize the surface finish.

In recent times, many organizations implementing total productive maintenance (TPM) have been failing in their attempts due to different barriers and challenges in TPM implementation. The purpose of this study is to evaluate the barriers before manufacturing organizations for adapting to proactive total productive maintenance (TPM) initiatives. It is observed that in the case of TPM, top management should be committed to involve from the beginning to implement and follow up, as this decision is complex and involve huge investment in the long term. Before starting implementation, top management should be convinced of the necessary justification, which requires analysis of various barriers such as lack of top management commitment, lack of human resource management, high turnover at top management level, lack of co-ordination between different departments. This paper has tried to develop a framework for analyzing the barriers in TPM implementation

Published: January 2023

The methods for improving energy and exergetic efficiency have been considered in this paper by using water as secondary coolant in evaporator with nano particles of Al2O3 and TiO2 mixed R718 refrigerant is investigated in this paper. Detailed energy and exergy analysis of multi-evaporators at different temperatures in the vapor compression refrigeration systems have been done in terms of performance parameter for R507a, R125, R134a, R290, R600, R600a, R410a, R407c, R404a and R152a refrigerants. The numerical computations have been carried out for both systems. The use of nano particles improves the energy and exergy performance significantly. The best thermodynamic performance is found using R152a and worst performance is observed using R410a.
Due to flammable nature of R290, R600, R600a and R152a , the R134a is recommended for domestic applications. The results were compared by using water in secondary circuit with nano refrigerants and without nano-particles used and it was found that use of nano-particles improves thermal performances significantly. The energy performance improvement in terms of COP and exergetic performance in terms of exergetic efficiency (rational efficiency) using TiO2 is better than using Al2O3 with R718 refrigerant in the secondary evaporator circuit.

A conventional sensor network is a radio network of sensor nodes with ability to sense physical parameters, store sensed data, carry out simple processing on data and forward the data through radio interface. The objective of such network is to push the data to a sink node which can then forward the data to server ( or cloud). However many real time applications includes sensors spread over long areas. As such they are treated as independent networks. Internet of Things is a new paradigm of connecting devices like microcontroller and smart objects to cloud. Using IoT services, we can now connect sensors to internet directly. In the proposed work more comprehensive state of art cloud extension of WSN through IoT has been focused, more focus on being towards bettering each of the current state of art building blocks including but not limited to sensor network, coordinator protocol, data analysis in sensor network, cloud services, IoT protocols and so on.
