Mobile Agent is an alternate strategy to compose a dignified distributed system. Mobile agent is a program that can transform one host to another host at time in places of their choices (Jump and Go). The comparison between the Mobile Agent platforms Grasshopper and JAMES Framework as a suitable architecture for distributed system. A comparison is made and a categorization is made based on the performance of the James and Grasshopper mobile agents, with an emphasis on the James and Grasshopper framework as a viable architecture for distributed systems for multi-agent organizations. The purpose of this research is to compare and contrast mobile agent platforms.

Plant diseases are widespread by a variety of pests, weeds and pathogens and can have devastating effects on agriculture if not treated in time. Farmers face a myriad of challenges due to adequate water supply, premature rain, storage facilities, and diseases of multiple crops. Plant diseases are a major threat to farmers with enormous production and economic loss. Identifying disease on a few hectares of farmland can be a daunting task, even in the presence of modern technology. Accurate and rapid disease prediction for early crop disease treatment has proven to be productive for healthy crops as well, minimizing personal financial loss. Many studies use modern deep learning approaches to improve the accuracy and performance of object detection and identification systems. Crop diseases are a constant challenge for smallholders, threatening income and food security. The proliferation of smartphones and recent revolutions in computer vision models has created a method of image classification in agriculture. Convolutional neural networks (CNNs) are considered the cutting edge of image recognition and offer the possibility of making timely and clear diagnoses. This article examines the performance of a pre-trained ResNet 34 model in the detection of plant diseases. The developed model can be used as a web application to detect seven plant diseases from healthy leaf tissue. A dataset containing images of 8,685 leaves. Captured in a controlled environment and established for model training and validation. Verification results show that the proposed method can achieve an accuracy of 97.2% and an F1 score of over 96.5%. It demonstrates the technical feasibility of CNN in plant disease classification and points the way to AI solutions for smallholders.

The Western Ghats is one of the 34th Mega Biodiversity hot spots at the global level due to its high number of endemic plant and animal species. That plant species, especially the endemics, have been reported and published in Red Data Book. Heterostemma dalzellii Hook. belongs to the family Apocynaceae is a twining undershrubs species, it is endemic to Western Ghats of India. The present distribution of H. dalzellii is only in India and it is restricted to the Diu, Daman, Dadar- Nagarhaveli, Maharashtra, and Goa. Recently discovered in the southeast Gujarat region. IUCN provided the status of many plants which are present in the Western Ghats. But due to the unavailability of the data, these plant is not appearing in IUCN data. There is an urgent need to evaluate their status as per IUCN categories as well as to undertake conservation measures to protect the habitat of the species. The major goal of the species recovery programme will be to re-establish the populations within their historical range. Their taxonomy will be reinvestigated to confirm their taxonomic distinctness. Population parameters will be collected for each population. H. dalzellii is one of the species that need to evaluate as per the IUCN category because of lacking primary and secondary data. In the present study, I am generating primary and secondary data for the purpose of standing a species in the IUCN category.

The plant family Boraginaceae worldwide distributed and its contained 145 genera. Carolus Linnaeus described the Cordia genus in the format of Cordia L., Sp. Pl. 1: 190 (1753). The genus Cordia L. (Boraginaceae) is a medicinally important taxon. The first species of Cordia dichotoma G. Forst. has been used for the treatment against fever, ulcers, dyspepsia, ringworm, etc. It has also been reported for its activities such as analgesic, antidiabetic and anti-inflammatory actions. Another second species, C. sinensis Lam., which is endemic to the northern Western Ghats, is a potential medicinal plant and is presumed to have similar biochemical activities. Since the species is consumed mainly in the crude form, it is difficult to establish the identity based on only leaf or stem characters. A comparative study has been carried out to authenticate the identity of these two species based on foliar anatomical characters. The anatomical sections of a leaf (TS), and petiole (TS) of both the species were observed under the bright-field microscope, and characters were documented. Though the diagrammatic outline of the leaf sections is similar, detailed anatomical characters are significantly different. The structure and number of the trichomes are observed abaxial and adaxial sides of the leaves. The trichomes were also found to be useful characters for identification. In the case of leaf, the number and arrangement of vascular bundles, arrangement of collenchyma at the lower epidermis, palisade cells, and distribution of storage cells are the major characters to differentiate both species. During the study, we also observed the detailed characters of the cuticular layer, trichomes, and stomatal characters. Rananculious type stomata and the presence of cystoliths in the basal cell of the trichome are the common characteristics observed in both species. On the basis of the primary study, the species can be differentiated based only on foliar anatomical characters. 

An elderly patient with a history of localized cutaneous melanoma cured by surgical skin resection, no longer followed by his dermatologist, presented to the emergency departement with an acute gastro-intestinal (GI) bleeding. Oesogastroduodenoscopy (OGD) showed a protuberant and ulcerated lesion, in the duodenal bulb, with pigmented spots in its center, very evocative of a melanoma. Histological results confirmed this hypothesis. CT scan identified multiple secondary locations. Latent metastasic melanomas revealed by GI bleeding after years of remission are rare and their outcome is severe. We highlight, in this paper, the importance of a regular lifelong monitoring patient with history of cutaneous melanoma, even localized, looking for any clinical sign that could suggest a recurrence or a digestive metastasis of his melanoma, in order to carry out the necessary examinations and treat the patient without delay.

The removal of hydrocarbons from contaminated soil is an essential practice because of environmental and health concerns, and in order to avoid further contamination of surface and groundwater. A variety of oil-contaminated soil remediation methods, categorized as physiochemical, biological and thermal remediation were compiled and summarized. However, the efficiency of these methods depends on several factors, such as the amount of spilled oil and the penetration depth of the oil into the soil, the type of oil and polluted soil, and the age and degree of contamination. With respect to remediation in the Niger Delta Region of Nigeria, it has been shown by studies that bioremediation and phytoremediation are the best methods that have been used in the area for the remediation of petroleum in soil due to the fact that it is cheap, easy to manage (even by the community), proved to be effective in enhancing biodegradation and environmentally safe. Finally, as there is no universal method that can be generally applied to completely remove the oil from contaminated sites, thus, the prevention of oil spills or leakages should be the first concern. However, if oil spills or leakages occur, a response should be taken immediately to minimize the potential environmental consequences. Furthermore, constant environmental monitoring, assessment, and evaluation to determine the level of damage that is caused by oil spills on the environment.

Abdominal pregnancy is a very rare obstetric complication which is extremely dangerious to the mother as well as the fetus. The diagnose can be difficult using ultrasounds beyond the first trimester,even then a high index of suspicion remains necessary. In this report, we present a primigravida woman accounted for pelvic pain and late periods into the Emergency room.

Summary The forestry regime aims at promoting the rational and sustainable management of resources in order to increase their contribution to the economic, social and cultural development of present generations, while preserving forest ecosystems and forest biodiversity for future generations. It was with this in mind that the legislator promulgated the decree of 4 April 1934, the first legal instrument on forestry adopted by the Belgian Parliament. Two years later, the decree of 13 June 1936 was added to the list and attempted to put all indigenous people on an equal footing with regard to forest access and use rights. After the Second World War, the decree of 11 April 1949 on forests had data of an economic nature that obliged the colonial authorities to adapt the forestry legislation. Over the years, the decree became obsolete, ineffective and unsuited to the political, economic, social and especially the global and sub-regional environment. In the same vein, law n°011/2002 of 29 August 2002 on the forestry code is the basic legislative text that regulates forestry management in the DRC. This law wipes out the existing texts, inherited from the colonial period, in order to meet the new socio-economic objectives that the State has assigned to the management of the forest estate. The results of our investigations in Basoko Territory confirm the marginalisation of local communities. On the one hand, they are not involved in the process because their specifications are very often not followed up. On the other hand, local communities are not involved in the management of industrial exploitation at the decision-making level.

In this article, we study one of the matrix analysis methods, which is the spectral decomposition method of the matrix, which is a very special case for the square and symmetric real matrix.

SLAP lesions remain a rare entity of the painful pathology of the shoulder under the labrobicipital complex, of difficult diagnosis given the atypical clinical symptomatology often vague with tests of different reliability although directing towards a strong positive presumption. The advent of imaging by injection of contrast product (arthro scanner and especially arthro MRI) has allowed a better understanding of this type of lesion but there are still variants of this complex which are radiologically limited between what is normal or pathological. Arthroscopy has allowed an unequalled precision of diagnosis with the possibility of adequate therapeutic management and very satisfactory results. Through this clinical case of a young patient with a chronically painful shoulder, we draw attention to this type of pathology, which is rare but not negligible.
