A Deep Learning based Model for Fruit Grading using DenseNet

Detecting the rotten fruits become significant in the agricultural industry. Usually, the classification of fresh and rotten fruits is carried by humans is not effectual for the fruit farmers. Human beings will become tired after doing the same task multiple times, but machines do not. Thus, this paper proposes an approach to reduce human efforts, reduce the cost and time for production by identifying the defects in the fruits in the agricultural industry. If we do not detect those defects, those defected fruits may contaminate good fruits. Hence, we proposed a model to avoid the spread of rottenness. The proposed model classifies the fresh fruits and rotten fruits from the input fruit images. For this work, we have used three types of fruits, such as apple, banana, and oranges. A Convolutional Neural Network (CNN) is used for extracting the features from input fruit images, and Softmax is used to classify the images into fresh and rotten fruits. The performance of the proposed model is evaluated on a dataset that is downloaded from Kaggle and produces an accuracy of 97.82%. The results showed that the proposed CNN model can effectively classify the fresh fruits and rotten fruits

Oral Candidiasis Review: Pathogenesis, Clinical Presentation, And Treatment Strategies

The candidiasis is an opportunistic infection commonly affecting the oral cavity. The most prevalent clinical symptoms of candidiasis seen in medical and dental practice is oral candidiasis. People who are extremely young, elderly, or already ill are more likely to develop the illness. The present review summarize classification, pathophysiology, laboratory diagnosis and treatment and management of oral candidiasis. Additionally, medicinal herbs and nutraceuticals can be explored as a safe, accessible, and cost-effective therapy option for oral candidiasis

Synthesis, characterization, biological and electrical conductivity studies of some Schiff base metal complexes

Metal complexes of VO(IV), Zr(IV), Th(IV) and UO2(VI) with Schiff base ligands derived from 4-nitrobenzoylhydrazide with 2-hydroxy-5-methylacetophenone (H2L1) or 2-hydroxy-5-chloroacetophenone (H2L2) have been prepared. All the complexes have been characterized on the basis of elemental analyses, magnetic susceptibility measurement, electronic and IR spectra and thermogravimetric analysis. The IR spectral data suggested that the ligands behave as dibasic tridentate moiety towards the central metal ion coordinating through phenolic oxygen, enolic oxygen and azomethine nitrogen atoms. The elemental analyses show a 1:1 metal:ligand stoichiometry for all the complexes except Th(IV) which has 1:2 stoichiometry. The thermal analysis evidenced that thermal transformations of complexes are processes according to TG curves including dehydration, thermolysis and oxidative degradation of Schiff base. The final product of decomposition is the most stable metallic oxide. The kinetic analysis of the thermogravimetric data was performed by using the Coats-Redfern method. Solid state electrical conductivity of the complexes has been measured in their compressed pellet form over a 310-413 K temperature range. All the complexes show semiconducting behavior as their conductivity increases with increasing temperature and a function of ionic size. All the complexes along with ligands were also screened for their antibacterial and antifungal activities. KEY WORDS: Aroylhydrazones, Metal complexes, Biological activity, TGA, Electrical conductivity Bull.

Phi Shape UWB Antenna with Band Notch Characteristics

In this paper a novel band notch antenna in UWB frequency range is designed using split rings. Split rings are overlapped with designed monopole to give phi shape. The slit gap gives band-notch operation from 5.1GHz to 6.29GHz and from 4.94GHz to 5.91GHz for SPSSR and SPSCR antennas respectively. Simulated and measured results are in good agreement

Case report on heavy eye syndrome

In high myopia, acquired esotropia can be present as strabismus fixus convergence also known as Heavy Eye Syndrome (HES). Although exotropia and hypertropia have been reported, patients typically present with diplopia due to increasing esotropia and hypotropia with limitations on abduction and elevation. We reported two cases of HES based on history and clinical examination, which includes anterior and posterior segment examination and squint evaluation. The MRI of both patients showed displacement of lateral rectus inferiorly and nasal shifting of superior rectus. In both the cases forced duction test (FDT) was positive for affected medial rectus (MR) when performed under local anaesthesia. Subsequently, they underwent loop myopexy of superior rectus (SR) with medical rectus (MR) along with MR recession for affected eye. Postoperatively, Case 1 had a residual esotropia of 18 prism dioptre (PD) and case 2 had 40 PD compare to preoperatively 70 and 80 PD respectively, measured with the krimsky test. Axial length lengthening and herniation of sclera between the SR and LR muscles are the two main contributors to HES. To stop additional herniation, the inter-muscular link must be restored. Loop myopexy is an elegant and effective procedure to achieve good cosmetic and functional results for HES

Modeling Activity and Target-Dependent Developmental Cell Death of Mouse Retinal Ganglion Cells Ex Vivo

Programmed cell death is widespread during the development of the central nervous system and serves multiple purposes including the establishment of neural connections. In the mouse retina a substantial reduction of retinal ganglion cells (RGCs) occurs during the first postnatal week, coinciding with the formation of retinotopic maps in the superior colliculus (SC). We previously established a retino-collicular culture preparation which recapitulates the progressive topographic ordering of RGC projections during early post-natal life. Here, we questioned whether this model could also be suitable to examine the mechanisms underlying developmental cell death of RGCs. Brn3a was used as a marker of the RGCs. A developmental decline in the number of Brn3a-immunolabelled neurons was found in the retinal explant with a timing that paralleled that observed in vivo. In contrast, the density of photoreceptors or of starburst amacrine cells increased, mimicking the evolution of these cell populations in vivo. Blockade of neural activity with tetrodotoxin increased the number of surviving Brn3a-labelled neurons in the retinal explant, as did the increase in target availability when one retinal explant was confronted with 2 or 4 collicular slices. Thus, this ex vivo model reproduces the developmental reduction of RGCs and recapitulates its regulation by neural activity and target availability. It therefore offers a simple way to analyze developmental cell death in this classic system. Using this model, we show that ephrin-A signaling does not participate to the regulation of the Brn3a population size in the retina, indicating that eprhin-A-mediated elimination of exuberant projections does not involve developmental cell death
