High processing and consumption generate huge quantities of solid organic wastes. Citrus waste represents approximately 40-50% of total fruit weight, which consists of rag (membranes and cores), pulp, seeds, and peel (albedo and flavedo), which are a potential source of value-added products including essential oils, carotenoids, pectin, dietary fibers, and polyphenols biofuel, etc. However, waste produced is discarded as waste in the environment, which causes a serious threat due to the presence of bioactive compounds. Recent research strategies on the integrated biorefinery approach explore various ways to utilize the waste obtained from the citrus wastes for their subsequent recovery of value-added products. Moreover, the citrus waste can be turned into various bio-products, viz., enzymes, biofuels, and biopolymers using the integrated biorefinery approach, which can optimize the development of green waste for sustainability and economic benefits. Given the sustainable solution for resource recovery and environmental management, the article reviews the latest advances in the novel valorization approach and valuation of the existing state-of-the-art green technologies for citrus waste utilization to bring a sustainable solution for increasing demand for food, fuel, and energy security. To achieve the zero-waste approach and industrial viability, more efforts should be given to scale-up green recovery techniques along with diverse product profiling.

By introducing cavity analogous to rhombus shape in photonic crystal waveguide center, slow light properties and buffering performance are studied. Numerical results through plane-wave expansion method and model field distribution through finite-difference time domain method show that both the rhombus cavity radii and some discriminatory rods around rhombus cavity have a plentiful effect on slow light properties and buffering fulfillment. By adjusting the cavity rod radii, we obtained high group index of 5163 with buffering bit length Lbit about 17.968 μm and delay time Ts reaching to 51.967 ps through the waveguide-cavity length of 3.02 μm. Moreover, low group velocity dispersion can be achieved, with governable positive and negative values. To regulate the optimal parameters to increase the group index and demonstrate the delay time performance, some discriminatory rods around rhombus cavity are adjusted in the upper and lower edges confronting each other in the waveguide, and ultra-high group index as exceedingly large as 22350 is obtained that is extremely higher than previous studies. Simultaneously, the corresponding buffer bit length Lbit and delay time Ts reach respectively to 25.8279 μm and 225.7783 ps through the waveguide-cavity length of 3.0306 μm. We designed a simple structure but a more generalized that may contribute a requisite theoretical basis for potential industrial applications in the storage capacity properties of high group index for optical buffering and optical communication systems.

Various conditions of welding speeds and the preheating on the bead on geometry were studied for uniformity of weld geometry. Visual examination, macro bead dimensional analysis, microhardness profile across the transverse section, microstructural analyses were performed to investigate the K-GTAW on electrolytic tough pitch copper. The results revealed that full penetration of 6 mm can be obtained in a single pass using keyhole mode in GTAW. Keyhole length and width were majorly affected by the welding speed and preheating temperature. Significant variations in weld bead geometry were observed even when high heat input conditions were applied without preheating. Uniform weld bead geometry of 5 mm bead width and depth to width ratio of 0.42 was obtained for a length of 80 mm using appropriate preheating of 300°C and heat input condition of 1.37 kJ/mm (resulted from 300 amps welding current, 120 mm/min welding speed and 15.3 volts voltage). In the uniform weld bead geometry, the weld and heat affected zones were consisted of coarse grains relative to base material, wherein the micro hardness variations were observed.

Although considered rare disorders, their prevalence in the general population is not well understood. We aimed to evaluate the clinical and genetic prevalence of lipodystrophy disorders in a large clinical care cohort. We interrogated the electronic health record (EHR) information of >1.3 million adults from the Geisinger Health System for lipodystrophy diagnostic codes. We estimate a clinical prevalence of disease of 1 in 20,000 individuals. We performed genetic analyses in individuals with available genomic data to identify variants associated with inherited lipodystrophies and examined their EHR for comorbidities associated with lipodystrophy.

The MOB is proposed by breaking the translational symmetry of the periodicity three times after introducing different types of cavities. In each time, we attained ultrahigh group index and highly Q-factor with highest delaying time. Ultrahigh group index of 21030 is obtained with Q-factor of 4309, delaying time of 70.1 ns, and buffer capacity of 8.41 bit. On the other hand, the bit rate and storage density turn into 117.73 Gb/s and 0.06121 bit/µm, corresponding to approximately 16.33 µm occupied by 1 bit for optical communication wavelength. Coupling a number of different types of cavities, higher Q-factor than that of an individual cavity can be obtained. It is shown that by coupling two cavities, the Q-factor is heightened to be 1.748 × 10 5 in low translational-symmetry case. We proposed a structure for promising application in optical signal processors and random access memories. Furthermore, we get longer delaying time and high Q-factor, which have important applications in low-threshold lasers, high finesse filters and high-speed switching.

It cannot be grown in temperate climates with severe winters. Therefore, genetic improvement of phalsa for cold tolerance is essential. In order to apply biotechnology through genetic transformation to enhance cold hardiness, a reliable and rapid micropropagation system is needed. Thus, developing the most dependable micropropagation protocols for phalsa was the primary goal of this research. Phalsa explants prepared from different tissues, including leaf, nodes, internode, and zygotic embryos, were collected from mature trees growing in the specialty plants house, cultured on MS medium supplemented with various cytokinins alone or along with auxins and incubated under a 10-hour photoperiod at ambient temperature. In vitro propagation of phalsa tissues through both organogenesis and somatic embryogenesis was achieved. Of these, single shoots were developed from nodal explants as a result of bud...

Structural and functional alterations in the lymphoid organs have been reported both in HME patients and experimental animals indicating a possibility of the dysfunction of immune system following exposure to CO seeds or its toxic anthraquinones (Panigrahi et al., 2014a). In the present study the mechanism of immune response of Rhein in splenocytes has been investigated by measuring functional assays of lymphocyte, cell surface receptor expression and analysis of cytokine levels. Results indicate that Rhein at a maximum dose of 10μM is non cytotoxic up to 72hours in splenocytes. In addition to its potential to decrease the allogenic response of T-cells, Rhein significantly suppresses the proliferation of the concavalin A (Con A) and lipopolysaccharide (LPS) stimulated splenocytes.

Principal challenges involved in this are designing the detachable top lid and positioning the appropriate stiffeners within the space available on the vessel for meeting functional and operational requirements of in-vacuum deflection to less than 5mm (0.196 in.) and it is limited to 1mm (0.039 in.) in certain areas on the vessel. Moreover, ASME code [3] does not have design formulation for this detachable top lid configuration directly, hence, there is a need to adopt the available recommendations ASME code [3], assess their applicability, adopt appropriate one, improvise and affect it and validate it by Finite Element Analysis (FEA).This paper presents the comprehensive design methodology adopted for INTF Vacuum Vessel design and optimization of various parameters to meet the operational and functional requirements within the constraints of other mandatory interfaces. This paper also presents its manufacturing plan, fabrication challenges and current status of vessel fabrication.Copyright © 2015 by ASME

Timely and sufficient supply of water is the most important requirement for agriculture. There is a continuous need of monitoring the moisture level at agriculture lands. The focus is on developing project with a simple GUI system along with mathematical modelling of a new and cost effective irrigating system. This paper introduces an automatic module to supply appropriate amount of water to the field by sensing the crop humidity requirement. It even reduces probability of soil erosion and protects the crop rotting due to over irrigation during heavy rainfall with advanced rainfall unit. This system will be economical in terms of hardware cost and power consumption. It proposes a humidity level sensor at field where sprinkling has to be done w.r.t. the quantity of water needed. The circuit monitors the water level of the tank, to prevent dry run and damage to pump.

The kernels were found to be rich in TPC ranging from 92.2 to 162.1 mg gallic acid equivalent/100 g. The free radical-scavenging activity in terms of inhibitory concentration (IC 50) ranged from 43.8 to 123.4 mg/ml and ferric reducing antioxidant potential (FRAP) from 154.1 to 243.6 FeSO 4 .7H 2 O μg/ml. A variation of 1-1.7 fold in total phenolic content, 1-2.8 fold in IC 50 by 2,2-diphenyl-1picrylhydrazyl (DPPH) assay and 1-1.6 fold in ferric reducing antioxidant potential among the examined kernels underlines the important role played by genetic background for determining the phenolic content and antioxidant potential of apricot kernel. A positive significant correlation between TPC and FRAP (r = 0.671) was found. No significant correlation was found between TPC and IC 50 ; FRAP and IC 50 ; TPC and physical properties of kernel. Principal component analysis demonstrated that genotypic effect is more pronounced towards TPC and total antioxidant capacity (TAC) content in apricot kernel while the contribution of seed and kernel physical properties are not highly significant.

Although the incidence of skin cancers in India (part of South Asia) is low, the absolute number of cases may be significant due to large population. The existing literature on BCC in India is scant. So, this study was done focusing on its epidemiology, risk factors, and clinicopathological aspects. Methods. A hospital based cross-sectional study was conducted in Punjab, North India, from 2011 to 2013. History, examination and histopathological confirmation were done in all the patients visiting skin department with suspected lesions. Results. Out of 36 confirmed cases, 63.9% were females with mean ± SD age being 60.9 ± 14.2 years. Mean duration of disease was 4.7 years. Though there was statistically significant higher sun exposure in males compared to females (P value being 0.000), BCC was commoner in females, explainable by intermittent sun exposure (during household work in the open kitchens) in women. Majority of patients (88.9%) had a single lesion. Head and neck r...

The results indicated that exposure of CO (0.5%) seeds in diet to rats differentially regulated 60 transcripts belonging to various metabolic pathways including, oxidative stress, xenobiotic metabolism, carbohydrate metabolism, cell cycle, apoptosis etc. The expression of AKT1, CAT, SOD1, CYP1A1, CYP2B1, TGF-β, BAX, CREB1, JNK1 and IL-6 were validated by the qRT-PCR. In addition, involvement of oxidative stress was observed due to marked depletion of glutathione, increase in lipid peroxidation and modulation of antioxidant enzymes in hepatic tissue of rats treated with 0.5-2.0% CO in diet. Furthermore, significant decrease in the levels of Phase 1 (EROD, MROD and PROD) and Phase 2 (QR and GST) enzymes following 0.5-2.0% CO exposure indicates the impairment of xenobiotic metabolism and possible accumulati...

Several studies have indicated that the general population is also exposed to BA owing to its release from furnace effluents and automobile exhausts in the environment. In several clinical studies, it has been shown that workers exposed to BA developed itching, burning sensation, erythema and hyperpigmentation of the skin, which could be an outcome of the dysregulated immune response. In this study, we have used female Balb/c mice as a model to study the immuno-inflammatory changes after systemic administration of BA (7.5mg/kgb.w. and 15mg/kgb.w.) for one week. BA exposed animals exhibited the signs of intense systemic inflammation as evident by enhanced DTH response, MPO activity, hyperplastic and dysplastic histopathological organization of spleen and lung tissue. Splenic evaluation revealed enhanced oxidative stress, upregulation...

Steps involve in chhang preparation includes cleaning and boiling of barley grains, cooling, addition of starter culture, fermentation, filtration and blending. The beverage was analysed for alcohol content, pH and titrable acidity using standard analytical methods. Results showed that the fermented beverage contains 5-7% alcohol, pH 3.6 to 3.8, acidity 0.55 to 0.65%.

Timely and sufficient supply of water is the most important requirement for agriculture. There is a continuous need of monitoring the moisture level at agriculture lands. The focus is on developing project with a simple GUI system along with mathematical modelling of a new and cost effective irrigating system. This paper introduces an automatic module to supply appropriate amount of water to the field by sensing the crop humidity requirement. It even reduces probability of soil erosion and protects the crop rotting due to over irrigation during heavy rainfall with advanced rainfall unit. This system will be economical in terms of hardware cost and power consumption. It proposes a humidity level sensor at field where sprinkling has to be done w.r.t. the quantity of water needed. The circuit monitors the water level of the tank, to prevent dry run and damage to pump.

The kernels were found to be rich in TPC ranging from 92.2 to 162.1 mg gallic acid equivalent/100 g. The free radical-scavenging activity in terms of inhibitory concentration (IC 50) ranged from 43.8 to 123.4 mg/ml and ferric reducing antioxidant potential (FRAP) from 154.1 to 243.6 FeSO 4 .7H 2 O μg/ml. A variation of 1-1.7 fold in total phenolic content, 1-2.8 fold in IC 50 by 2,2-diphenyl-1picrylhydrazyl (DPPH) assay and 1-1.6 fold in ferric reducing antioxidant potential among the examined kernels underlines the important role played by genetic background for determining the phenolic content and antioxidant potential of apricot kernel. A positive significant correlation between TPC and FRAP (r = 0.671) was found. No significant correlation was found between TPC and IC 50 ; FRAP and IC 50 ; TPC and physical properties of kernel. Principal component analysis demonstrated that genotypic effect is more pronounced towards TPC and total antioxidant capacity (TAC) content in apricot kernel while the contribution of seed and kernel physical properties are not highly significant.

They are affected by primary diseases ranging from inflammatory to neoplastic as well as are secondarily involved in almost all terminal diseases. Histopathological examination of lungs is vital in diagnostic work up of all lung diseases. The present study was conducted in year 2012–2013 in which 50 cases were analyzed. Pulmonary congestion and edema was found as the most common diagnosis followed by pneumonia and tuberculosis.

Although the incidence of skin cancers in India (part of South Asia) is low, the absolute number of cases may be significant due to large population. The existing literature on BCC in India is scant. So, this study was done focusing on its epidemiology, risk factors, and clinicopathological aspects. Methods. A hospital based cross-sectional study was conducted in Punjab, North India, from 2011 to 2013. History, examination and histopathological confirmation were done in all the patients visiting skin department with suspected lesions. Results. Out of 36 confirmed cases, 63.9% were females with mean ± SD age being 60.9 ± 14.2 years. Mean duration of disease was 4.7 years. Though there was statistically significant higher sun exposure in males compared to females (P value being 0.000), BCC was commoner in females, explainable by intermittent sun exposure (during household work in the open kitchens) in women. Majority of patients (88.9%) had a single lesion. Head and neck r...

The results indicated that exposure of CO (0.5%) seeds in diet to rats differentially regulated 60 transcripts belonging to various metabolic pathways including, oxidative stress, xenobiotic metabolism, carbohydrate metabolism, cell cycle, apoptosis etc. The expression of AKT1, CAT, SOD1, CYP1A1, CYP2B1, TGF-β, BAX, CREB1, JNK1 and IL-6 were validated by the qRT-PCR. In addition, involvement of oxidative stress was observed due to marked depletion of glutathione, increase in lipid peroxidation and modulation of antioxidant enzymes in hepatic tissue of rats treated with 0.5-2.0% CO in diet. Furthermore, significant decrease in the levels of Phase 1 (EROD, MROD and PROD) and Phase 2 (QR and GST) enzymes following 0.5-2.0% CO exposure indicates the impairment of xenobiotic metabolism and possible accumulati...

Several studies have indicated that the general population is also exposed to BA owing to its release from furnace effluents and automobile exhausts in the environment. In several clinical studies, it has been shown that workers exposed to BA developed itching, burning sensation, erythema and hyperpigmentation of the skin, which could be an outcome of the dysregulated immune response. In this study, we have used female Balb/c mice as a model to study the immuno-inflammatory changes after systemic administration of BA (7.5mg/kgb.w. and 15mg/kgb.w.) for one week. BA exposed animals exhibited the signs of intense systemic inflammation as evident by enhanced DTH response, MPO activity, hyperplastic and dysplastic histopathological organization of spleen and lung tissue. Splenic evaluation revealed enhanced oxidative stress, upregulation...
