[EN] Proper cell selection is determinant to optimize systems and reduce risks for new and high demanding areas such as electromobility. Thermal performance must be an indispensable selection criterion to avoid thermal issues in these fields, so cells should be correctly characterised and modelled. In this paper, an improved cell selection methodology that focuses on the thermal performance criterion especially for fast charging applications is proposed. After a first selection, two cell candidates were characterised and their heat generation was modelled and compared. With the selected cell, heat generation rate was determined and a 3C fast charge was performed to evidence the predicted thermal performance. The improved methodology identified a cell with an advantageous entropic heat coefficient (EHC) for fast charging, decreasing the heat energy generation by 54% concerning the other candidate cell, which results in optimisation of the thermal management system (TMS). This emphasizes the importance of proper cell selection based on thorough thermal characterization.

Ayurveda describe the organization of the body in term of doshas, dhatus and malas.  Twacha is one among the updhatus which provide protective layer over the body that protect from the heat,  cold & external infection. The union of Shukra (spermatozoa) & Shonita (ovum) while being cooked  (processed by heat) give rise to the formation of seven twaka (skin) just like formation of cream when milk  is boiled. Acharya Susruta and other Acharyas are described twaka shareeram in detail. Acharya Susruta  defined Twacha as Upadhatu of mamsa dhatu.Twacha is one among the Panch jyanendriya, which carry  sensation of touch.& It covers external part as well as internal part of body. Since antiquity human being  often suffered from many type of diseases, out of them skin disease is one of the major problem for the  community, because there is a change in the structural appearance of the skin & it make entire body ugly.  There are different theories among the Acharyas regarding the number of layers. Acharyas Charaka  consider that Twacha is made up of six layers where others. Acharya Susruta considers seven layers. In this  layers of twacha, different type of diseases observe in different layers. Out of this, a very commonly seen  “Visarpa” disease is found in one of the Twacha layer.“Visarpa” is one among the type of skin disorder  which is common and acute disorder of Twacha. Acharyas describe symptoms of Visarpa like – spreading  character, Inflammation, Pricking type of pain, Fever, Vesicles, Segmental spreading, Redness, Rapid  spreading. Although Twacha has been explained in our classic, we get very vague and very less description  about the disease related to Twacha shareera. And it is outermost protective layer of the body, so it becomes  essential to know the structural and anatomical changes occur in the Visarpa. Now a day’s Visarpa disease  largely spread in the hu

Ayurveda adapts laws of nature and propounds number of applied doctrines for the understanding of life, health and  diseases. Human lumbar vertebrae supports the weight of the upper body. Loads lifted and carried by the upper  extremities cause significant loading and stress to the vertebral bodies. Katishool can be a result of conditions affecting  the discs between the vertebrae, ligaments around the spine and discs, spinal cord and nerves, muscles of lower back  and various other factors. Increasing age brings about inevitable changes in the structure, shape and function of the  human vertebrae.. What factors mediate this degenerative progression in lumbar spine? What leads a large portion of  the population to manifest spondylosis, even early on their lives? Hence the conclusion’s put forth are that the Ruja, Stambha, Khanjata, Shopha, Asthi vikruthi lakshana’s are seen  in the Kati Sandhi during trauma ,sports, routine work injuries are due to the involvement of structural changes in  lumbar vertebrae which were identified by the radiological findings..Vata dosha is the major factor behind the  whole pathogenesis involved in Katishoola. All the Nidanas of Vatavyadhi & Vata prakopa can be  regarded as Nidana of Katishoola..Degenerative changes are more likely to occur in women as compared  to men.&nbsp
