Environmental sciences ,GE1-350 - Abstract
Efficiency of photovoltaic (PV) systems is decreased by mismatch losses resulting from uneven panel irradiation. Current compensation techniques that inject compensatory current and measure currents by periodic row short-circuiting are unavoidably blackout-causing. In this work, a novel current compensation technique is presented that dynamically measures and reacts to variations in irradiance using light sensors on each panel. The program compiles these data to determine the overall irradiance of each row and to precisely modify the injected current to sustain output without any interruptions to operation. The proposed approach lowers mismatch losses more effectively than traditional techniques, as demonstrated by MATLAB/Simulink simulations of seven shading patterns. Under center shading, the proposed approach raised system efficiency by 36%. These results indicate a move towards more flexible solar energy solutions by implying that sensor-driven data analytics can increase PV system operational efficiency and reliability.

The low-cost magnet less switched reluctance motor (SRM) speed-torque characteristics are perfectly suited for electric vehicles (EVs) drive performances are better than polyphase machines. The main drawback of SRM for EVs is torque ripple, it can be mitigated by optimal design aspects. In this study, to design SRM by changing the position of the stator and rotor pole, an increasing number of poles are investigated with optimum geometry. This paper presents the design procedure for EV applications of 250 kg mass, developed power of 2.9 kW and acceleration of 30 kmph. SRM rotor modification with two different cases of design of SRM with exterior rotor case with three-phase stator configuration 8/6, 10/6 and design of SRM with an interior rotor with three and four phases stator configuration 6/4, 8/6. The simulation was carried out using an electromagnet infolytica simulation package. The conditions of flux linkages, static torque, and rotor configurations are obtained using finite elements. FEA is used to verify the design of the SRM from an electrical standpoint. The results and performance analysis of the SRM drive were compared and analyzed for both cases. It is observed during the static and transient analysis that, the torque ripple in the 8/6 interior rotor design is lesser than in the exterior rotor design. The Interior rotor configuration 8/6 model may best be suited for EV’s high-speed application due to its low torque ripple characteristics compared to other models.

The magnet-less switched reluctance motor (SRM) speed-torque characteristics are ideally suited for traction motor drive characteristics and its advantage to minimize the overall cost of on-road EVs. The main drawbacks are torque and flux ripple, which have produced high in low-speed operation. However, the emerging direct torque control (DTC) operated magnitude flux and torque estimation with voltage vectors (VVs) gives high torque ripples due to the selection of effective switching states and sector partition accuracy. On the other hand, the existing model predictive control (MPC) with multiple objective and optimization weighting factors produces high torque ripples due to the system dynamics and constraints. Therefore, existing DTC and MPC can result in high torque ripples. This paper proposed a finite set (FS)-MPC with a single cost function objective without weighting factor: the predicted torque considered to evaluate VVs to minimize the ripples further. The selected optimal VV minimizes the SRM drive torque and flux ripples in steady and dynamic state behaviour. The classical DTC and proposed model were developed, and simulation results were verified using MATLAB/Simulink. The proposed model operated in SRM drives experimental results to prove the effective minimization of torque and flux ripples compared to the existing DTC. [ABSTRACT FROM AUTHOR]

Background: Andrographis paniculata (Burm.f.) Nees has been well-researched for its immunomodulatory effects. Objective(s): To investigate the immunomodulatory effects of standardized A. paniculata extract (SAPE) in healthy adults. Materials and methods: The study was an open-label, single-centre study conducted for 30 days. Thirty participants with absolute lymphocyte counts of 1000–4000 cells/mm3 were enrolled and were instructed to ingest 200 mg of SAPE daily for 30 days. The participants visited the clinic at baseline, and days 3, 7, and 30. Immune cells such as NK cell (CD3-CD16+CD56+), T cells (CD3+), T helper cells (CD3+CD4+), T cytotoxic cells (CD3+CD8+) were measured using flow cytometry. Serum cytokines that include interferon gamma (IFN-γ), interleukin-4 (IL-4), interleukin-2 (IL-2), interleukin-12 (IL-12), and tumor necrosis factor alpha (TNF-α) were measured using ELISA. The SAPE used in this study was a standardized proprietary extract (AP-Bio®/KalmCold®) developed from the leaf extracts of A. paniculata. Results: SAPE increased T cells, T helper cells and significantly increased IFN-γ, IL-4, and decreased IL-2 at day 30. A subgroup analysis of participants with absolute lymphocyte counts of 1000–3000 cells/mm3 indicated that there is a significant increase in the T cells, T helper cells at day 7 and 30 and significant increase in IFN-γ, IL-4 and decrease in IL-2 at day 30. There was no treatment related adverse effects following SAPE intake for 30 days. Conclusion: Supplementation of SAPE resulted in immunomodulatory effects evidenced by its effects on immune cells and cytokines and it was found to be safe and tolerable.

Introduction: In India, the prevalence of gallstones is considered as a major public health problem and among diabetic patients the prevalence is still more increasing. Presence of Diabetic Autonomic Neuropathy (DAN) is a triggering factor for gallbladder diseases among diabetic patients. Aim: To compare the gallbladder volume and contraction index between diabetic patients and non diabetic healthy controls. Materials and Methods: A cross-sectional study was conducted in a tertiary care hospital at Chennai for a period of six months from June 2019 to December 2019. The total 90 subjects were divided into two groups of 45 each, group A consist of 45 known Type I or Type II diabetes mellitus (DM)and group B with 45 non diabetic healthy controls. The gallbladder volume was assessed initially in the fasting state, then the patient was asked to have fatty meal and again the gallbladder volume was measured after two hours for all the patients and the gallbladder contraction index was calculated using these values. Autonomic neuropathy grading was done after performing neuropathy assessment tests and the association between the gallbladder contraction index and grading of autonomic neuropathy was analysed. Results: The mean fasting and postprandial gallbladder volume were much higher among diabetic patients compared to non diabetic controls and similarly the gallbladder contraction index was lesser among diabetic patients compared to the controls (16.6±5.9 cm3 , 4.03±1.8 cm3 ) and (32.08±11.7 cm3 , 17.4±10.6 cm3 ) the difference was found to be statistically significant (p-value

Asynchronous NOCs are most prominent in present SOC designs, due to their low dynamic power consumption, modularity, heterogeneous nature, and robustness to the process variations. Though asynchronous designs are proved efficient over synchronous counterparts, they have some severe drawbacks when area and speed are considered, due to complex handshake control circuits which increase the static power loss. Quasidelay insensitive (QDI) class of asynchronous NOCs based on 2-phase encoding is proved beneficial for speed and throughput enhancement but with complex design. The work has introduced lightweight minimal buffer router based on LEDR encoding to design a low power, high speed with compact NOC architecture. Then, minimal buffer router with FSM-based arbiter and priority assigner block is designed to enhance the speed, power, and area. This proposed work achieves zero dynamic power consumption with a total power consumption of less than 0.082 W with a router latency of 0.8 ns.

Bilateral cleft lip and palate ,presurgical nasoalveolar molding ,unilateral cleft lip and palate ,Dentistry ,RK1-715 - Abstract
Cleft lip and palate (CLP) is the most common congenital craniofacial anomaly. Rehabilitation of CLP generally requires a team approach. Alveolar and nasal reconstruction for these patients is a challenge for the reconstructive surgeon. Various procedures have been attempted to reduce the cleft gap, so as to obtain esthetic results postsurgically. The presurgical nasoalveolar molding (PNAM) technique, developed by Grayson, is a new approach to presurgical infant orthopedics. PNAM reduces the severity of the initial cleft alveolar and nasal deformity. Thus, it enables the surgeon and the patient to enjoy the benefits associated with repair of a cleft deformity that is minimal in severity. This article presents a brief insight into PNAM with a case series of three different cases (one unilateral and two bilateral) which underwent PNAM treatment and gave an excellent surgical prognosis.

Aim and objective To compare the antibacterial activity of root canal filling materials namely zinc oxide eugenol and Endoflas FS with or without the incorporation of Triclosan. Materials and methods The study consisted of four groups, with 15 samples in each group: group I (zinc oxide eugenol paste), group Ia (zinc oxide eugenol paste + 2.5% Triclosan), group II (Endoflas FS), and group IIa (Endoflas FS + 2.5% Triclosan). A double layer agar well diffusion test was used to evaluate the antibacterial activity against Enterococcus faecalis. The zones of microbial inhibition were measured at the end of 24 hours, 6th day, and 29th day. Results On intergroup comparison, the difference in the antibacterial activity was found to be highly significant (p Conclusion Incorporation of 2.5% triclosan into zinc oxide eugenol and Endoflas FS enhanced the antimicrobial activity of both the root canal filling materials with lasting antimicrobial activity even at the end of the 29th day. Clinical significance The antimicrobial efficacy of a root canal filling material is an ideal requirement, which will help in combating the residual microflora present in the root canal system following chemomechanical preparation. The addition of an antimicrobial agent such as triclosan to the root canal filling materials, enhances their antimicrobial efficacy significantly and thus, rendering the pulpectomy-treated tooth with a better prognosis.

Cyprinus carpio, Superoxide Dimutase (SOD), Catalase (CAT), Glutathione Peroxidase (GPx), and Gulutathione-S-Transferrase (GST) - Abstract
In the present investigation, the fresh water fish C. carpio and Cadmium were used. Bio assays were conducted to find LC50 96hr value of the metal to the fishes and it was found to be 1.5%. Then groups of fishes were reared in various sublethal concentrations of Cadmium for 30days. The liver from the control and Cadmium –treated fishes was dissected out for the estimation of Superoxide Dimutase (SOD), Catalase (CAT), Glutathione Peroxidase (GPx), and Gulutathione-S-Transferrase (GST). In treated fishes, the liver antioxidant enzymes increased under metal toxicity suggesting the initiation of the production of these enzymes to suppress the action of ROS. The liver might have severely affected by Cadmium as it is the site of multiple oxidative reactions. Key words: Cyprinus carpio, Superoxide Dimutase (SOD), Catalase (CAT), Glutathione Peroxidase (GPx), and Gulutathione-S-Transferrase (GST).

Context: The survival of atraumatic restorative treatment (ART) restorations would probably increase if near total elimination of cariogenic microorganisms could be done in the process of cavity cleaning before going ahead with the restoration. Thus, use of naturally occurring disinfecting agents for achieving this goal could herald a new beginning in the field of contemporary minimum intervention dentistry. Aims: To evaluate the efficacy of hand instruments in excavating dental caries and comparatively evaluate the roles of Aloe vera and propolis as potential cavity disinfecting agents after minimally invasive hand excavation of dental caries. Settings and Designs: Experimental, in vivo intergroup split mouth, randomized clinical trial. Subjects and Methods: The study included Group I (Control), Group II (A. vera) and Group III (propolis). Ten patients with three teeth each have occlusal/occlusoproximal lesions suitable for ART were selected. Dentinal samples were collected three times from each tooth viz., preexcavation, postexcavation and postdisinfection of the cavities. These dentinal samples were subjected to microbiological analyses for total viable count. Statistical Analysis Used: Repeated measures of analysis of variance (ANOVA) with Bonferroni post-hoc test and one-way ANOVA with Tukey post-hoc test. Results: In all the three groups, significant amount of bacteria were left behind after hand excavation. Group II and Group III, in which cavities were treated with A. vera and propolis extracts respectively, showed a significant reduction in the bacterial counts when compared to control the group. Conclusions: Hand excavation alone does not completely eliminate bacteria, which may predispose treated teeth to secondary caries. Both propolis and A. vera extracts can be used as potential natural disinfecting agents, thereby embracing the concept of phytotherapy in minimum intervention dentistry.

Introduction: The routine antenatal sonographic investigations of the umbilical cord are limited for assessment of number of umbilical vessels and doppler evaluation of umbilical blood flow. With the advancements of the sonographic techniques it is now possible to have more detailed evaluation of umbilical cord. There exist only few literatures on assessment of umbilical cord cross-sectional area during pregnancy to provide a baseline reference value. Aim: To establish the reference intervals of cross-sectional area of the umbilical cord during gestation and to find the correlation of umbilical cord cross-sectional area with the foetal anthropometric measurements. Materials and Methods: This study was conducted among 214 normal pregnant women who underwent a routine antenatal sonogram during gestational age ranging from 24-39 weeks in the Department of Radiodiagnosis. The umbilical cord crosssectional area was calculated at a plane immediately close to the umbilical cord insertion to the foetal abdomen. The following foetal parameters were studied: Biparietal Diameters (BPD), Head Circumference (HC), Abdominal Circumference (AC), Femur Length (FL), and Estimated Foetal weight (EFW). The relationship between foetal anthropometric measurements and umbilical cord cross sectional area was assessed using spearman rank correlation. The 5th, 10th, 50th, 90th and 95th percentiles of umbilical cord cross-sectional area were calculated for each gestational groups using polynomial regression analysis. Results: A statistically significant correlation was observed between cross-sectional area of umbilical cord with both gestational age and foetal anthropometric parameters. The mean age of study population was 25.08±3.5 years and the mean gestational age was 34.42±2.5 weeks. We observed a strong correlation between head circumference and umbilical cord cross-sectional area. Conclusion: The mean umbilical cord cross-section area increases steadily with gestational age for up to 34 weeks and then it declines. Umbilical cord cross-sectional area can be easily measured and hence it can be included in routine antenatal sonographic evaluations to predict the perinatal outcome. Careful monitoring of the pregnancy is needed in case of abnormal cross-sectional area measurements.

Objectives: Rhinoscleroma is a rare infectious disease of the upper respiratory tract caused by Klebsiella rhinoscleromatis. Apart from mandating an appropriate antibiotic therapy, it poses a unique challenge to the pathologists since it can clinically simulate a malignancy. The main objective was to study the cases of rhinoscleroma of the respiratory tract in a period of 3 years with an emphasis on the clinico-pathologic features. Methods: We report a retrospective analysis of 7 cases, histopathologically diagnosed at our centre as rhino-scleroma. The topography ranged from nasal mucosa (3), pharynx (2) and larynx (2). Results: Histopathological examination in all cases showed diffuse aggregates of foamy macrophages (Mikulicz cells) containing intracytoplasmic basophilic organisms; admixed with plasma cells in a fibrotic stroma. The overlying epithelium appeared atrophic to focally hyperplastic. The age ranged from 36–67 years, involving both genders. The significant clinical history included a nasal block without anosmia, atrophic rhinitis with septal perforation to subglottic stenosis, requiring immediate surgical intervention. In 4 of the 7 cases, the working clinical diagnosis was stipulated as a malignancy. Conclusions: Rhinoscleroma can affect different regions in the upper aero digestive tract. A lack of awareness and a delay in the diagnosis of this disease can lead to complications including upper airway obstruction, physical deformity, and rarely, sepsis. In addition, it must be remembered that the treatment of rhinoscleroma is challenging and requires a prolonged course of antibiotics to achieve a definite cure and avoid relapses.

A total of 39 patients of 5-9 years with occlusoproximal carious lesion on primary maxillary or mandibular molars were selected and randomly allotted into two groups i.e Group A (Equia Forte) and Group B (Tetric N Ceram). A total of 78 restorations (39 teeth for each group) was placed using Equia Forte and Tetric N Ceram using a split mouth design and were evaluated for a period of 12 months at regular time intervals using FDI criteria by two blinded examiners for esthetic, functional and biological properties. The data were analyzed using one way ANOVA for intragroup comparison and student t test for intergroup comparison. There was no statistically significant difference seen at baseline, 3, 6, 9 and 12 months for esthetic, functional and biological properties within the group. On inter group comparison, there was no statistically significant result observed except for functional property at 6 months with a p value of 0.02. The current study suggests that both Equia Forte and Tetric N Ceram can be a choice of restorative material in class II carious lesions in primary molars.

Background: Grahaṇimihira tailam is an unexplored ayurvedic oil preparation which consists of 34 ingredients. The efficacy of this traditional ayurvedic medicine is undisputable. Proper clinical standardization of this formulation will go a long way in securing greater recognition for it. The main objective of this study was to develop standardization parameters for the formulation in a multidisciplinary way. Materials and Methods: A simple and efficient method for the quantification of umbelliferone by high performance thin layer chromatography was developed and validated. Presence of the major fatty acids and their percentage were assessed by using gas chromatography-mass spectrometry (GC-MS). Various physio-chemical parameters, microbiological load, aflatoxins and mineral oil were also evaluated. Spread plate method was used for checking microbial contamination. Results: The results were validated as per standard protocols. Quantitative estimation revealed the percentage of umbelliferone to be in the range of 0.88-0.98 (w/w). GC-MS analysis of sample led to the identification of 14 fatty acids, in which linoleic acid was obtained as the major fatty acid. Microbes, aflatoxins and mineral oils were found to be absent in the tailam. Conclusion: The results which give the quantitative estimates of various physico-chemical parameters can be adopted to establish new standards for analysis of batch-to-batch variation and this data will facilitate shelf life studies in the future.

PIXELS ,DEEP learning ,BINARY codes ,CLASSIFICATION - Abstract
There are numerous image classification strategies are developed in deep learning. However, due to the complexity of images, conventional image classification strategies have been incapable to meet real application needs. As the amount of pixel information rises, the classification becomes more difficult. However, CNN is widely used method for object identification in picture due to its simple and accurate, but still, it remains hazy which strategies are most supportive for analysing and distinguishing the objects in pictures. In this paper we introduced a CNN network and clustering-based technique called IBCNN to perform classification based on patch extraction. The proposed method can accomplish their goals in the following four different ways: a) Automatic Kernel selection; b) resilient patch size selection; c) CNN layer; and d) pooling layer modification. In addition, it also modifies the pooling layer with average value and calculate the pixel size. The proposed method was applied on ten different image datasets. Finally, the proposed model is compared to three benchmarking models: such as WCNN, MLP, and ELM-CNN to estimate its performance. The obtained results shows that the proposed method gives competitive results compared to the other models. [ABSTRACT FROM AUTHOR]

Introduction: There is an established relationship between stature and various body parts like head, trunk, upper and lower extremity. This allows forensic expert to estimate stature from different parts of the body. Many studies have been conducted in many ethnic groups to estimate stature from hand and foot dimensions. Objectives: The purpose of this cross sectional study is to estimate stature from hand and foot dimensions in South Indian origin student population. Materials and Methods: Four anthropometric measurements viz. hand length, hand breadth, foot length and foot breadth were taken independently on the left and right side of each individual. Besides these, stature and weight of each subject were also recorded. Only right handed subjects were included in the present study. Results: In this cross sectional study of south Indian population, hands and feet dimensions were utilized to predict the stature of a person. The study includes 398 persons (149 males and 149 females) aged between 17 and 30 years. The average stature among males was 167.6 ± 6.2 and ranged between 151cm and 167.6cm. The average stature among females was 152.5 ± 4.9 and ranged between 142cm and 165cm. Males have larger hand and foot dimensions than females. The sex differences are highly significant in left foot length, right foot length, left hand breadth and right hand breadth; and significant in right foot breadth. All the parameters of hands and feet showed statistically significant positive correlation with stature in the present study and thus can be successfully utilized for stature estimation. Conclusion: The present cross sectional study emphasizes the utility of dimension of hands and feet in estimating stature by law enforcement agencies and forensic scientists, especially in mutilated and dismembered human remains. Keywords: Foot breadth, Foot length, Hand Breadth, Hand length, Stature.

Aims The aim of the present study is to evaluate the effect of cavity disinfection with 2% chlorhexidine (CHX) and Ag-Au nanoparticles on microleakage and resin tag penetrability of composite restoration under in vitro conditions. Materials and methods Twenty-five human permanent molars extracted for therapeutic reasons were used in the study. Class V cavity of standard dimension was prepared on the buccal and lingual surfaces of the teeth. The teeth were randomly allocated into two groups based on the cavity disinfectant used; group I being 2% chlorhexidine gluconate (chlorhexidine FGM) and group II being cavity disinfectant containing Ag-Au nanoparticles (nanocare gold). In both the groups, the dentin was etched with 37% phosphoric acid and cavity disinfectants were applied following which dentine bonding agent and composite resin were applied and cured. The specimens were then viewed under stereomicroscope and scanning electron microscope for evaluation of microleakage and resin tag formation, respectively. Results The results were statistically analyzed using independent 't' test. No significant difference was seen between the two groups with respect to the microleakage and resin tag penetration values (p >0.05). Conclusion Cavity disinfectant containing Ag-Au nanoparticles had no effect on the sealing ability and resin tag penetrability of composite resin in permanent molars when compared with 2% CHX. Clinical significance Use of Cavity disinfectant containing Ag-Au nanoparticles with etch and rinse system can be preferred as it satisfies the ideal property of a cavity disinfectant which includes excellent antimicrobial action and non-detrimental effect on the sealing ability and resin tag penetrability.

COVID-19 ,ECONOMIC impact of disease - Abstract
With COVID-19, the Indian economy is experiencing a significant declination, which was clear over the ongoing quarters even before the emergency struck. In the second from last quarter of the current financial year, the economy developed at a six-year low pace of 4.7%. With every one of these issues hitting the universe of work from multiple directions, organizations are thinking that it's hard to continue in this condition. They are compelled to take intense choices, for example, chopping down the compensations, giving formal notices to employees and settling on other cost-cutting measures. The flare-up has introduced new barricades for the Indian workforce and particularly for the day by day wage and legally binding laborers. Sensex also crashed in the year 2022 due to the impact of covid and war. This paper provides the detailed reviews about the impact of the covid-19 on Indian Economy. [ABSTRACT FROM AUTHOR]

Traditionally welding is considered as an art rather than a science. The quality of the weld is dependent on the skill and intuition of the welder. The welding process is mostly not reliable and labor-intensive. The solution to the problems in welding lies in utilizing intelligent welding techniques where in the selection of weld parameters like voltage, current, speed etc and defect control is done intelligently by the automated welding system. The intelligent welding system shall comprise elements, viz., control system, sensing, design and modeling of process and application of artificial intelligence. The application of intelligent welding system has developed into a new field of automation called as ‘Integrated Computational Welding Engineering (ICWE)’. The welding of titanium and its alloys is predominantly dependent on the skill of the welder. Majority of research and industrial practice is based on the traditional manual welding process and hence it is prone to defects deterioration of metallurgical, mechanical and corrosion properties. There is scope in adopting ICWE in welding of titanium and its alloys.

Methotrexate (MTX) is used as an anticancer drug in many types of cancer associated with organ toxicities. It generates free radicals responsible for tissue damage in organs like testis. Coconut water, a natural drink known for its nutritive values also possess components, which are rich in antioxidants. The present study was a novel study to evaluate the benefits of yellow and green varieties of coconut water in testicular damage caused by methotrexate in experimental animals. The study proved that, both the varieties of coconut water restored testicular structure and functions by recovering sperm function, testicular enzymes, antioxidant enzymes and improvement in tissue microscopy. We conclude that both green and yellow coconut water are beneficial and can be used as a natural remedy for methotrexate induced testicular toxicity.

This paper discusses the impact of wind penetration on frequency control of a thermal dominated system considering Generation Rate Constraints (GRC) and dead band non-linearities. The hidden inertia emulation and coordinated operation of conventional power generation systems with wind energy can effectively alleviate the frequency excursions during sudden load disturbances. Conventional energy storage device like Flywheel Energy Storage (FES) system can be used in conjunction with wind integrated power system to overcome the intermittent nature of power generation. Thyristor Controlled Series Compensator (TCSC) is found to be effective in damping low frequency oscillations in weak tie-lines and supplement the frequency regulation. A stochastic population based evolutionary computation technique - Particle Swarm Optimization (PSO) is used to tune the controller gains. A strategy comprising inertia control, coordinated operation of conventional generation units with wind energy and TCSC-FES has been proposed to enhance the frequency regulation which is effective in controlling low frequency oscillations as established by the simulation results.

T23 is a low alloy ferritic steel used for boiler super heater and re-heater tubes and water panels in complex fuelled power plants as they exhibit superior high temperature strength and creep behaviour compared to other low alloy ferritic steels. T23 steel is in bainitic structure which holds greater toughness than tempered martensite and also they possess increased resistance to thermal fatigue. With the help of T23 steel, the weight and piping component of the boiler can be reduced. The microstructure of the weldment without proper Post Weld Heat Treatment (PWHT) was not in equilibrium state which led to the secondary hardening during subsequent exposure at high temperature. So there occurred a significant increase in hardness due to non-tempered weld joints and decrease in toughness. Therefore, Post Weld Heat Treatment for T23 steel is necessary. Using Tungsten Inert Gas (TIG) process, the T23 steel was welded under suitable welding parameters (welding current, voltage and shielding gases). A study was done to know the effect of Post Weld Heat Treatment on T23 steel and also the influence of welding parameters. Hardness of T23 steel was measured. The heat treated specimen is examined through Optical microscope and Scanning Electron Microscope. Finally it was noticed that the Post Weld Heat Treatment has enhanced the mechanical properties as well as the metallurgical arrangement of the T23 steel.

Cleft lip and palate (CLP) is the most common congenital craniofacial anomaly. Rehabilitation of CLP generally requires a team approach. Alveolar and nasal reconstruction for these patients is a challenge for the reconstructive surgeon. Various procedures have been attempted to reduce the cleft gap, so as to obtain esthetic results postsurgically. The presurgical nasoalveolar molding (PNAM) technique, developed by Grayson, is a new approach to presurgical infant orthopedics. PNAM reduces the severity of the initial cleft alveolar and nasal deformity. Thus, it enables the surgeon and the patient to enjoy the benefits associated with repair of a cleft deformity that is minimal in severity. This article presents a brief insight into PNAM with a case series of three different cases (one unilateral and two bilateral) which underwent PNAM treatment and gave an excellent surgical prognosis.

Innovation is an incorporation of radio sign in optical fiber transmission inside of system foundations that are thought to be financially savvy, pragmatic and moderately adaptable framework setup for whole deal transport remote signs. This venture proposes a Next era PON construction modeling backings RoF and OFDMA signal coordination without WDM lasers, and exhibit that 10-Gb/s OFDMA and three RF signals at 2.1GHz are transmitted more than 20km SMF in a 32-ONU in both upstream and downstream bearing. A security control unit and an optical switch are utilized associating four Optical Line Terminations (OLTs) with everyone serving just 32 Optical Network Units (ONUs). Insurance control unit gathers data of ONUs served by each OLT, and when an OLT falls flat, it will educate an active OLT to help its unique ONUs together with the burden served by the fizzled OLT.

Introduction The routine antenatal sonographic investigations of the umbilical cord are limited for assessment of number of umbilical vessels and doppler evaluation of umbilical blood flow. With the advancements of the sonographic techniques it is now possible to have more detailed evaluation of umbilical cord. There exist only few literatures on assessment of umbilical cord cross-sectional area during pregnancy to provide a baseline reference value. Aim To establish the reference intervals of cross-sectional area of the umbilical cord during gestation and to find the correlation of umbilical cord cross-sectional area with the foetal anthropometric measurements. Materials and methods This study was conducted among 214 normal pregnant women who underwent a routine antenatal sonogram during gestational age ranging from 24-39 weeks in the Department of Radiodiagnosis. The umbilical cord cross-sectional area was calculated at a plane immediately close to the umbilical cord insertion to the foetal abdomen. The following foetal parameters were studied: Biparietal Diameters (BPD), Head Circumference (HC), Abdominal Circumference (AC), Femur Length (FL), and Estimated Foetal weight (EFW). The relationship between foetal anthropometric measurements and umbilical cord cross sectional area was assessed using spearman rank correlation. The 5th, 10th, 50th, 90th and 95th percentiles of umbilical cord cross-sectional area were calculated for each gestational groups using polynomial regression analysis. Results A statistically significant correlation was observed between cross-sectional area of umbilical cord with both gestational age and foetal anthropometric parameters. The mean age of study population was 25.08±3.5 years and the mean gestational age was 34.42±2.5 weeks. We observed a strong correlation between head circumference and umbilical cord cross-sectional area. Conclusion The mean umbilical cord cross-section area increases steadily with gestational age for up to 34 weeks and then it declines. Umbilical cord cross-sectional area can be easily measured and hence it can be included in routine antenatal sonographic evaluations to predict the perinatal outcome. Careful monitoring of the pregnancy is needed in case of abnormal cross-sectional area measurements.

Some of the plant species of the genus Salacia are considered as an important anti-diabetic drug in ayurveda. Among them S. chinensis, S. fruticosa and S. oblonga possess great medicinal importance, mostly because of its promising anti-diabetic activity. The increasing demand of this drug, resulted in a huge decline in its availability and it is replaced by spurious ones mainly because of lack of adequate quality standards. There is now a felt need to develop a systematic approach for the authentication of these plants and to develop well-designed methodologies for its standardization. The present study focused on the Pharmacopoeial parameters like pharmacognostical characterization and preliminary phytochemical screening of these three species. which were found to be sufficient to evaluate the raw material and can also be used as reference standards for the quality control/quality assurance purposes. The pharmacognostic study revealed that there are specific diagnostic features for distinguishing these three species among themselves and also from other related species. The external morphology of these three species are also shows variation in their colour, odour and taste. Both the species of Salacia ie, S. chinensis is having bitter taste and S. fruticose is with astringent taste whereas S. oblonga has no characteristic taste of its own. The TLC profile showed similar pattern in S. chinensis and S. fruiticosa where as S. oblonga showed more band in the profile than that of the other two. This reveals that the S. chinensis and S. fruiticosa having similar compounds responsible for therapeutic efficacy, whereas S. oblonga has more chemical constituents.
