Nowadays, under increasing climate change effects on the environment, we can observe increasing number of extreme phenomena, including meteorological and hydrological ones. One of such phenomena are floods. The objective of this article is the assessment of basic flood characteristics seasonality in the annual distribution. Analysis were performed based on time series of daily flow values recorded in the years 1951–2014 in three gauging stations located on rivers in Easter Poland, in upper Wieprz catchment. Floods were defined according to TLM algorithm and were assumed to be all cases of flow occurrence exceeding 10% read from FDC (flow duration curve) (Q10). Seasonality was analysed using Markham’s Seasonality Index and Period of Seasonal Concentration, analysis of autocorrelation function (ACF) as well as proposed by the author Seasonal Winter Floods Index. The distribution of floods during year indicates one flood season in year which occurs in the spring.

Abstract. Usually a precursor alone might not be useful as an accurate, precise, and stand-alone criteria for the earthquake parameters prediction. Therefore it is more appropriate to exploit parameters extracted from a variety of individual precursors so that their simultaneous integration would reduce the parameters's uncertainty. In our previous studies, five strong earthquakes which happened in the Samoa Islands, Sichuan (China), L'Aquila (Italy), Borujerd (Iran) and Zarand (Iran) have been analyzed to locate unusual variations in the time series of the different earthquake precursors. In this study, we have attempted to estimate earthquake parameters using the detected anomalies in the mentioned case studies. Using remote sensing observations, this study examines variations of electron and ion density, electron temperature, total electron content (TEC), electric and magnetic fields and land surface temperature (LST) several days before the studied earthquakes. Regarding the ionospheric precursors, the geomagnetic indices Dst and Kp were used to distinguish pre-earthquake disturbed states from the other anomalies related to the geomagnetic activities. The inter-quartile range of data was utilized to construct their upper and lower bound to detect disturbed states outsides the bounds which might be associated with impending earthquakes. When the disturbed state associated with an impending earthquake is detected, based on the type of precursor, the number of days relative to the earthquake day is estimated. Then regarding the deviation value of the precursor from the undisturbed state the magnitude of the impending earthquake is estimated. The radius of the affected area is calculated using the estimated magnitude and Dobrovolsky formula. In order to assess final earthquake parameters (i.e. date, magnitude and radius of the affected area) for each case study, the earthquake parameters obtained from different earthquake precursors were integrated. In other words, for each case study using the median and inter-quartile range of earthquake parameters, the bounds of the final earthquake parameters were defined. For each studied case, a close agreement was found between the estimated and registered earthquake parameters.

Abstract:-                         Skin diseases commonly known as Dermatitis, are occurs all over the world at significant levels. The skin is most important part of the body which protects the body from various external factors.                                     In the ayurvedic literature all skin diseases were included under the “Kushtharog” which is classified in two divisions i.e. Mahakushtha and kshudrakushtha. In ayurveda vicharchika is described under kshudrakushtha. All the clinical features of vicharchika are similar to eczema in modern dermatology.                                        Eczema which is also known as Atopic dermatitis , is refers to a group of inflammatory conditions, it affects the outer layer of the skin the epidermis.characterized by dry  itchy skin, which is classified in two phase i.e. acute phase and chronic phase. Dermatitis results from a variety of different causes and has various patterns.                        In ayurveda there are many formulations for internal and topical application mentioned by the different Acharays in samhitas, which can shows significant effect on vicharchika. Methodology:-  In this case Arogyavardhini vati and Gandhak rasayan administer orally and Karanj tailam topically   given to the patient. Result:- There is significant effect on clinical signs and symptoms of patient and size of affected area. Conclusion:- In this case study combine use of  Arogyavardhini vati and gandhak rasayan orally and Karanj tailam topically was very effective in reducing signs, symptoms, and size of affected area of vicharchika. .
