Vehicle refinement recognition related technology research is widely used in the field of mine monitoring and management systems, road traffic command and control, etc. As researchers develop and implement the target recognition technology system based on deep learning algorithms, designing a target recognition algorithm with excellent performance is a research priority within the field of vehicle monitoring. In this paper, we propose an Efficient Net algorithm based recognition method for vehicle front-end and vehicle rear-end recognition to address the shortcomings of the current methods used for vehicle front-end and vehicle rear-end recognition, and verify the reliability of the algorithm using experiments. Algorithm systematically investigates model scaling, the backbone network makes extensive use of the MBConv structure to extract the feature maps, which cuts short the time required for model training, and the structure introduces the SE module to perform global averaging pooling operations in the channel dimension direction to enhance model performance, so that the network has the dual advantages of network model size and recognition accuracy at the same time. Based on the above findings, we improve the inverse residual module of the backbone feature extraction network EfficientNet by introducing the coordinate attention mechanism (CA) to average the spatial feature information in X-axis and Y-axis dimensions respectively, with the feature layer size and number of channels unchanged, and change the residual edge to shorten the input and output of high-dimensional channels to improve the accuracy of model feature extraction. Meanwhile, this paper introduces a depth-separable convolutional neural network and agent-normalized activation in the mobile flip-flop convolutional module to offset the two different dimensions of X-axis and Y-axis between each convolutional layer but the two main sources of non-normalization, so as to achieve the improvement of the target detection rate and accuracy.

The stability constant of a complex produced from the interaction between metal salt and organic ligand can be explained using cyclic voltammetric measurements. In the present work, we are interested in investigating the electrochemical behavior of the complexation between bulk copper chloride salt and succinic hydrazide as a ligand. Metal ions specially copper was found to form complexes through the interaction with nitrogen and hydroxyl group or carbonyl group of the ligand (succinic hydrazide) which can be studied by decreasing in the height peak of current and measuring the (anodic/cathodic) shift of potentials using cyclic voltammetry. The cyclic voltammetric behavior was studied using solid glassy Carbon electrode (SGC) as working electrode, silver/silver chloride put in saturated KCl solution as reference electrode and platinum wire, auxiliary electrode from (1 to -1)V potential window at 290.65 K.

The present study was planned to investigate the changes in morphological and biochemical parameters of in vitro-grown potato (cultivar Cardinal and Desiree) plants under osmotic stress conditions induced by various concentrations of sorbitol, mannitol, (0, 0.025, 0.05, 0.10 or 0.15 M) sucrose (0, 2, 3, 4, 6 and 8%) and polyethylene glycol (PEG: MW-4000: 0, 5, 10, 15 and 20%). Nodal segments (1.0 cm long) from healthy in vitro-grown potato plantlets were inoculated on Murashige and Skoog’s medium with different concentration of above-mentioned drought stress inducing agents. Data recorded on 60th day of incubation exhibited severe reduction in most of the growth parameters at 0.10 and 0.15 M of sorbitol and mannitol respectively; and at 5-10% PEG. Similar results were observed when the sucrose level was varied from 3% except for the number of roots and plant dry weight which exhibited an increase on increasing the sucrose level. Data collected for total soluble protein content and activity of an antioxidant enzyme (superoxide dismutase) unveiled an overall increasing trend in osmotic stressed potato plants suggesting their major action in detoxification of active oxygen species produced under osmotic stress. Overall results indicated potato cultivar Desiree to be more stress-tolerant than the cultivar Cardinal. PEG turned out to be the most toxic osmoticum while sucrose being the least one.

The research was led with the aim of dehydrated fruit processing from indigenous fruit mimusops kummel using the application of hot thin layer dryer. The drying process was performed at drying temperature (55, 60 and 65OC), drying air volumetric flow rate (1 and 2 m3/sec) and drying time (4 and 5hr); respectively. The compositional analysis of fresh and dehydrated mimusops kummel was performed. The amount phytochemicals in the dehydrated mimusops kummel was determined and reported. The values for flavonoid, saponins, tannins, total phenol, oxalate and phytate were 46.45±2.02 mg/100g, 6000.00±2.00 mg/g, 294.20±0.55 mg/100g, 57.46±1.015mg/100g, 18.90±0.30 mg/g and 104.74±2.18mg/100g; respectively. Result of minerals concentration in dehydrated fruits for Fe, 15.01±0.59 mg/L, Na 1.72±0.06 mg/L, K 3.66±0.14 mg/L, Ca 8.14±0.06 mg/L and Zinc 2.54 ±0.16 mg/L were assessed; respectively. Sensory characteristics of dehydrated mimusops kummel fruits results indicated that the product manufactured with a drying temperature of 55oC, drying time 4 hr and air flow rate of 1m3s-1 was made-up as the most acceptable products as compared to the other products dehydrated with different drying parameters. Development and quality characteristics of dehydrated fruit from wild edible mimusops kummel can create business opportunity and contribute to food and nutrition security towards the utilization of processed wild edible fruits.

The research focuses on the topic of epidemic diseases in Riga during World War I (1914–1918) and the Latvian War of Independence (1918–1920). Although World War I ended in 1918, in several parts of the world smaller scale armed conflicts still continued. Latvia was one of the states where war continued until 1920; therefore, this time period is also included in the research. In parallel with hostilities, several epidemic diseases (typhoid, dysentery, cholera and others) erupted in Latvia, and in 1918, when the world was hit by the Spanish flu, one of the most devastating pandemics of all time, it impacted the territory of Latvia as well, particularly Riga. The research focuses on the spread of diseases, their victims, control, preventive measures and other aspects.

Small and medium-sized enterprises (SMEs) tend to have an advantage over competitors due to their strategic plans. Meanwhile, some of the strategic factors considered important to have a competitive advantage include human resource development, knowledge management, and Information and Communication Technology. These have been observed to be creating and maintaining a superior position for competitors but there is a need for a comprehensive understanding of the state-of-art of competitive advantage by entrepreneurs or academics. Therefore, this study aimed to classify and identify scientific publications as well as to conduct a thematic analysis of current literature to create an extensive and detailed understanding of competitive advantage in SMEs. This involved the use of a Systematic Mapping Study (SMS) to examine scientific publications related to competitive advantage based on the focus, locus, and type of research from time to time. The results classified competitive advantage based on the overview of previous research topics and trends.

The Coronavirus Disease 2019 (COVID-19) which is caused by Severe Acute Respiratory Syndrome coronavirus-2 (SARS-CoV-2) was first reported in December 2019 in Wuhan city of China. Even the public health sector experts could not anticipate that the virus would spread rapidly to make the worst worldwide crises in over 100 years. Although, the World Health Organization (WHO) declared the COVID-19 as a public health emergency on January 30 of 2020, but it was not until 11th March of 2020, when the WHO declared it a global pandemic. Unlike the SARS coronavirus outbreak in 2002 and the Middle East Respiratory Syndrome (MARS) in 2012, the epidemiology of SARS-CoV-2 is different, therefore, they could not be used as a suitable model for predicting the future of this pandemic. Our comparative model is 1918-19 Spanish Influenza pandemic. This article was aimed to highlight the key similarities and differences of both pandemics. Similarly, various possibilities for the future course of COVID-19 are also highlighted.

This essay examines controversies in the Western World around the practice of veil worn by Muslim women in public. It brings together two usually separate domains of inquiry, Islamic Feminism and Western Feminism, where I argue that these two domains need addressing to generate new insights and move scholarly debates that have become polarized in turn. The first strand is Western Feminists’ critiques of the practice as a tool of oppression and masculine domination. The second is a minority in a minority among Islamic Feminists who find the veil empowering. The aim is to unravel the underlying contradictions and blind‐spots that characterize many of the arguments for and against the veil. This juxtaposition can provide an insight with new theoretical and empirical points of departure for reflecting on the implications of criticism that is largely uncalled for, which aims to police women\'s bodies and ways of dressing in western liberal democracies. If at all any oppression is seen, it depends on the political dynamics of the state as well as the psychosocial space in which the individual, who sports it, dwells. It is utterly reductionist to criticize the choice to veil, which is an instrument of autonomy. In the process the paper also deals with body dissatisfaction and how stressful beauty standards play havoc with women’s being, which various ways of veiling may help and bring authentic attitude to their identities.
