The present investigation aims to reuse the heat rejected in the condenser unit of an NH3-based dairy plant to preheat the groundwater used for pasteurization of milk. A detailed thermodynamic analysis (both energetic and exergetic) of the refrigeration unit of an existing dairy plant and the boiler unit used for pasteurization is carried out in the current work. The chemical exergy of the air–water vapour mixture and the standard Indian coal is considered while analysing the evaporative condenser and the boiler unit. Cascading of the existing system with a transcritical vapour compression cycle is proposed to effectively use the heat rejected by the combined system to preheat the boiler feed water. A comparative study for different modifications, such as the inclusion of an expander and an ejector in place of the throttle valve in the top cycle of the proposed cascade system, is carried out. Additionally, the cascade systems are being analysed for two different refrigerants, i.e., CO2 and N2O. The study demonstrates that the cascade system with an expander employing N2O as the refrigerant gives the maximum benefit in terms of saving of $16.5 to $21.5 per day, 1.5 to 2% reduction in total CO2 emission, and a 2.5% reduction in total exergy destruction, as compared to the existing NH3 system.

In this state-of-the-art review, various adsorbents (i.e., Metal-Organic Framework (MOF), Activated Carbons and their composites, Carbon Molecular Sieve (CMS) and zeolites) for CO2 adsorption both at low and high-pressure applications (i.e., pre- and post-combustion CO2 capture, adsorption heat pumps employing CO2 as refrigerant) are explored. The most suitable candidate, i.e., the various grades of activated carbons (ACs), is identified based on their equilibrium uptake (isotherm data), rate of adsorption (kinetic data), isosteric heat of adsorption and cost. The study presents a comprehensive review on the basis of various models of adsorption isotherms and kinetics, their merits and demerits, and their applicability, especially in the context of CO2-adsorbent pairs. The literature shows that the activated carbons with high surface area, pore volume and better pore network results in higher equilibrium uptake and faster kinetics. A comparative analysis presented in the review work highlights that high-grade activated carbons having higher absolute uptake, also result in higher net uptake, i.e., the deciding factor for selecting the adsorbents for adsorption-based refrigeration and heat transformation applications. The comparative study clearly shows that most of the MOFs with high surface area outperform the best-activated carbons in equilibrium CO2 uptake. However, their high heat of adsorption, slower kinetics and significantly high cost comes in their way of commercialization for high/low-pressure CO2 adsorption applications. One of the notable observations of the review work is that adsorbents that perform better in low-pressure applications may not be a handsome candidate for high-pressure applications, as both mechanisms are different. Various isotherm models are compared based on the R2 value of the fitted data. The comparison clearly demonstrates that some of the models, i.e., (Langmuir, Freundlich), give better predictions at low-pressure conditions while some (Toth, D-A, Modified D-A, and D-R) give a better prediction for high-pressure adsorption. Some isotherm models take care of the surface heterogeneity, hence suitable for AC-CO2 pair. Most importantly, the compiled data for the adsorption isotherms and kinetics will be useful for further analysis and design of adsorption systems and selection of adsorbents, especially for CO2 adsorption systems suitable for green refrigeration/heat pump and carbon capture application.

The Gondwana rocks of the Athgarh Formation extend along the Mahanadi River valley in eastern India. Various models assign fluviatile, lacustrine, fluvio-deltaic, marine shelf, braided stream, and alluvial environments for their deposition. The Athgarh sub-basin extends from the type area Athgarh towards southeast till Bhubaneswar, as suggested in previous studies, which were mostly confined to the north of the Mahanadi River valley. However, the present study focused on the area south of the valley till Bhubaneswar. Discontinuous, relatively flat-topped, elevated escarpments as higher as ~ 170 m above M.S.L. trending ~ N-S and running parallel to the Mahanadi River valley are exposed in the Khordha and the Cuttack districts of Odisha. These were first identified in the satellite imagery and later cross-checked in the field. Our observations suggest that these outcrops are remnants of a paleo-river bed of the Mahanadi River which gradually migrated towards northwest as a result of tectonic uplift on an older normal fault, giving rise to a horst-and-graben structure. The lithological characteristics of the sandstone deposits exposed to the south of the Mahanadi River valley suggest that these might have been the product of a mega-scale deposition in a fluviatile environment.

A 2-D transient heat and mass transfer analysis is carried out on a longitudinal finned reactor suitable for adsorption-based green refrigeration/heat pump systems employing CO2-activated carbon pair. The study is carried out for a 1 kg adsorbent at constant charging/discharging pressure of 40 bar and 65 bar, respectively, for a fixed charging/discharging time of 300 s. Effects of various geometric parameters viz… reactor aspect ratio (AR), fin height and length, and number of fins (Nf) are studied to achieve an optimum reactor configuration based on maximum CO2 uptake. The results indicate that the addition of fins is crucial for enhancing the CO2 uptake for lower ARs. It is observed that the AR = 7.8; with 32 fins resulted in a maximum CO2 uptake of 1.25 kg/kg of adsorbent. The increment of 9–40% CO2 uptake is observed for all reactor configurations with Nf = 32. The gravimetric analysis revealed the existence of optimum reactor configurations for maximum CO2 uptakes. Based on the optimized conditions, equivalent annular finned models are analyzed for the same mass of the adsorption vessel. The results indicated that similar CO2 uptake could be obtained with lesser annular fins for lower ARs. Moreover, the current study is extended to analyze the desorption performance of optimized reactor configurations under high-pressure conditions. The results confirmed the best desorption performance for the reactor with AR = 7.8 for all external heating fluid temperatures. An increment of 495 and 637% is obtained for AR = 7.8 with Nf = 0 and 32, respectively w.r.t. AR = 0.35 with Nf = 0 at 400 K. [ABSTRACT FROM AUTHOR]

A comprehensive 2-D transient heat and mass transfer analysis is carried out to identify the best reactor configuration in terms of better charge and discharge characteristics for a CO2-activated carbon (Maxsorb III)-based sorption systems. Reactors with different aspect ratios (AR) ranging from 0.35 to 7.8 are analysed for a wide range of convective heat transfer coefficient (h), constant pressure charging, and discharging cases. Effects of external cooling/heating fluid temperature, convective heat transfer coefficient (h), operating pressures are studied for both the charging (1–100 bar) and discharging (65–110 bar) cases. The adsorption cell with AR= 7.8 showed the best performance for CO2 adsorption/desorption in a fixed charge/discharge time of 300 s. For charging at 100 bar pressure, the reactor with AR= 7.8 resulted in an increment of 23.34% in CO2 uptake and reduction in maximum bed temperature by 27 K compared to that of the reactor with AR = 0.35. For h = 700 and 500 W/m2 K, the reactor with AR = 7.8 adsorbs 1300 g and desorbs 832 g of CO2/kg of adsorbent at 100 bar and 65 bar for external cooling and heating fluid temperature of 293 K and 800 K, respectively. The study concludes that better discharge performance can be attained by proper selection of AR even at a lower heating fluid temperature as the reactor with AR = 7.8 at 600 K can desorb 46 to 131 g of extra CO2 w.r.t. all ARs at 800 K. The proposed reactor configurations are supposed to play a vital role in designing of adsorption-based green refrigeration and carbon capture systems. [ABSTRACT FROM AUTHOR]

Pressure-driven, shear-driven and combined pressure and shear driven flow of a non-Newtonian Sisko fluid through rectangular channels is investigated. Inclusion of the aspect ratio in the formulation yields a highly nonlinear partial differential equation, which is not reported in the existing literature. Thus, neither analytical nor numerical solution to this equation is available in the open literature. In the present study, the partial differential equation, describing the flow, is solved employing the finite difference method. Explicit method is adopted, and the solution for the non-dimensional velocity and wall shear stress is obtained. An exact solution for the flow of a Sisko fluid, for a special case (for non-Newtonian index 2), through large parallel plates (aspect ratio to be zero) is obtained. Expression for the friction factor, including the effect of the aspect ratio, is given. The effects of the aspect ratio, Sisko fluid parameter, non-Newtonian index on the non-dimensional velocity distribution and shear-stress distribution are analyzed both for shear-thinning and shear-thickening fluids. The results indicate that for pressure-driven flow, the effect of the aspect ratio on the velocity is negligible when it is less than 0.1. In case of shear-driven flow and combined pressure and shear driven flow also, the characteristics of flow through large parallel plates exist in nearly 50% of the channel for the aspect ratio of 0.1 or less, which means that for up to 50% of the channel, near the core, the parallel plates assumption will generate reasonably accurate results.

Experimental studies are carried out to characterize an indigenous, coconut shell based, activated carbon suitable for storage of natural gas. Properties such as BET surface area, micropore volume, average pore diameter and pore size distribution are obtained by using suitable instruments and techniques. An experimental setup is developed to estimate the equilibrium methane adsorption capacity and adsorption/desorption kinetics. The experimental isothermal uptake data is used to fit four different isotherm models. Using the constants obtained for the D–A isotherm model the variation of heat of adsorption and adsorbed phase specific heat with equilibrium pressure and temperature are obtained. Similarly Henry's Law coefficients, important at low pressure and low uptake regime are also obtained. Finally using the kinetic data and a linear driving force model, constants in the kinetic equation are obtained. Results show that the indigenous material used in this study offers reasonably high natural gas storage capacity and fast kinetics and is suitable for adsorbed natural gas (ANG) applications. It is expected that this study will be useful in the design and development of ANG systems based on this indigenous material. [ABSTRACT FROM AUTHOR]

Abstract: This article deals with the relationship between vocabulary (total number of distinct oligomers or “words”) and text-length (total number of oligomers or “words”) for a coding DNA sequence (CDS). For natural human languages, Heaps established a mathematical formula known as Heaps’ law, which relates vocabulary to text-length. Our analysis shows that Heaps’ law fails to model this relationship for CDSs. Here we develop a mathematical model to establish the relationship between the number of type of words (vocabulary) and the number of words sampled (text-length) for CDSs, when non-overlapping nucleotide strings with the same length are treated as words. We use tangent-hyperbolic function, which captures the saturation property of vocabulary. Based on the parameters of the model, we formulate a mathematical equation, known as “equation of word organization”, whose parameters essentially indicate that nucleotide organization of coding sequences are different from one another. We also compare the word organization of CDSs with the random word distribution and conclude that a CDS is neither similar to a natural human language nor to a random one. Moreover, these sequences have their unique nucleotide organization and it is completely structured for specific biological functioning. [Copyright &y& Elsevier]

The magnetohydrodynamic (MHD) flow of a third grade fluid through a rectangular channel, considering the effect of aspect ratio, has been investigated. The flow considered is steady, laminar, incompressible and hydro-dynamically fully developed. The equation, describing the flow, is a highly non-linear partial differential equation (PDE) with remote possibility of having an exact solution and even numerical solution also is very difficult to obtain. A combination of the homotopy perturbation method (HPM) and integral method (IM) has been employed to solve the non-linear PDE which is scarce in open literature. The results of the present study are compared with the results obtained by the least square method (LSM) of the MHD third grade fluid flow through a rectangular channel, without the effect of aspect ratio and are found to be in close agreement. The results indicate that the flow field is significantly affected by the aspect ratio which should be considered for practical applications. In all the available literatures of the third grade fluid flow, the aspect ratio effect is neglected and this simplifying assumption reduces the highly complicated non-linear PDE to a non-linear ordinary differential equation (ODE). The novelty of the subject work lies in the inclusion of the effects of aspect ratio in the governing equation describing the flow of a third grade fluid through a channel and solving this by a combined analytical method (HPM and IM). Further, the effects of the Hartmann number and non-Newtonian third grade fluid parameter on the flow filed are discussed. [ABSTRACT FROM AUTHOR]

Background : Type 2 diabetes is a significant public health concern that affects over 537 million adults worldwide. Oral antidiabetic (OAD) failure can be a complex management issue in patients with type 2 diabetes. Insulin glargine U-300 is a newer type of basal insulin with more consistent pharmacological effects than traditional insulin glargine.This study aimed to assess the safety and effectiveness of insulin glargine U-300 as compared to insulin glargine U-100 in Indian type 2 diabetes patients who had experienced OAD failure.This is a record-based observational study conducted on type 2 diabetes patients who had experienced OAD failure.The study involved 389 cases (189 on insulin glargine U-300 and 200 on insulin glargine U-100). It was found that 56.6% and 58.1% of patients had reduced fasting glucose levels below 130 mg/dl after 1 month of treatment, and 78.8% and 76.1% had a reduction after 3 months following the use of insulin glargine U-300 and insulin glargine U-100, respectively. In patients on glargine U-300 and insulin glargine U-100, the mean fasting plasma glucose decreased from 241.05 ± 65.93 mg/dl at baseline to 142.61 ± 55.19 mg/dl (p < 0.05) and similarly from 250.68 ± 61.41 to 140.27 ± 48.29 mg/dl (p < 0.05) at the end of the first month, respectively. The incidence of hypoglycemia was comparatively fewer in patients using insulin glargine U-300 as compared to those using insulin glargine U-100 (8.1% vs. 6.7%, p < 0.05).The results suggest that insulin glargine U-300 is an effective and safer treatment option than insulin glargine U-100 for Indian patients with OAD failure.

Background: Gestational diabetes mellitus (GDM), a common medical condition affecting a high number of pregnant women worldwide, is characterized by high blood glucose levels that develop during pregnancy, usually in the second or third trimester, in women with no prior history of diabetes. While GDM usually resolves after delivery, it can have significant short-term and long-term adverse effects on both the mother and the fetus. Though insulin therapy is the recommended primary treatment, there exists limited evidence comparing the safety and effectiveness of different long-acting insulin analogues, including glargine U-100 and detemir insulin.The study aimed to compare the effectiveness and safety of long-acting insulin analogs, glargine U-100 and detemir insulin, in hyperglycemic pregnancy.This record-based observational study involved 64 subjects, with data collected from medical records. The study assessed demographic data, glycaemic parameters, incidence of hypoglycemia, and neonatal outcomes.The results showed that both insulins were effective in reducing glycaemic levels, but glargine U-100 was associated with better glycemic control, fewer hypoglycemic episodes and less need for dose intensification. The results showed that both insulins were safe when considering infants’ health assessed at 6 months.The study concluded that glargine U-100 may be a preferred treatment option for hyperglycemic pregnancy. Further studies are needed for optimizing treatment strategies in hyperglycemic pregnancies.Objective: Gestational diabetes mellitus (GDM), a common medical condition affecting a high number of pregnant women worldwide, is characterized by high blood glucose levels that develop during pregnancy, usually in the second or third trimester, in women with no prior history of diabetes.
