Internet addiction, neuropsychotic stability and emotional state

The article deals with Internet addiction, neuropsychic stability and emotional state. The hypothesis about the presence of a connection between Internet addiction and neuropsychic stability and mood in senior schoolchildren and junior students was tested using the following methods: "Chen Internet Addiction Scale", CIAS scale as adapted by V.L. Malygina and. K.A. Feklisov, the identification of neuropsychic stability "Forecast", the SAN method (well-being, activity, and mood). The processing was carried out using descriptive statistics methods and the N-KruskalWallace criterionВ статье рассмотрены интернет-зависимость, нервно-психическая устойчивость и эмоциональное состояние. Проверена гипотеза о наличии связи интернет зависимости с нервно-психической устойчивостью и настроением у старших школьников и студентов младших курсов с помощью методик: «Шкала Интернет-зависимости Чена», шкала CIAS в адаптации В.Л. Малыгина и. К.А. Феклисова, выявления нервно-психической устойчивости «Прогноз», методики САН (самочувствие, активность, настроение). Обработка проводилась при помощи методов описательной статистики и критерия Н-Краскала-Уоллеса criterio

The BNO-LNGS joint measurement of the solar neutrino capture rate in 71Ga

We describe a cooperative measurement of the capture rate of solar neutrinos by the reaction 71Ga(\nu_e,e^-)71Ge. Extractions were made from a portion of the gallium target in the Russian-American Gallium Experiment SAGE and the extraction samples were transported to the Gran Sasso laboratory for synthesis and counting at the Gallium Neutrino Observatory GNO. Six extractions of this type were made and the resultant solar neutrino capture rate was 64 ^{+24}_{-22} SNU, which agrees well with the overall result of the gallium experiments. The major purpose of this experiment was to make it possible for SAGE to continue their regular schedule of monthly solar neutrino extractions without interruption while a separate experiment was underway to measure the response of 71Ga to neutrinos from an 37Ar source. As side benefits, this experiment proved the feasibility of long-distance sample transport in ultralow background radiochemical experiments and familiarized each group with the methods and techniques of the other.Comment: 7 pages, no figures; minor additions in version

Measurement of the Solar Neutrino Capture Rate by the Russian-American Gallium Solar Neutrino Experiment During One Half of the 22-Year Cycle of Solar Activity

We present the results of measurements of the solar neutrino capture rate in gallium metal by the Russian-American Gallium Experiment SAGE during slightly more than half of a 22-year cycle of solar activity. Combined analysis of the data of 92 runs during the 12-year period January 1990 through December 2001 gives a capture rate of solar neutrinos with energy more than 233 keV of 70.8 +5.3/-5.2 (stat.) +3.7/-3.2 (syst.) SNU. This represents only slightly more than half of the predicted standard solar model rate of 128 SNU. We give the results of new runs beginning in April 1998 and the results of combined analysis of all runs since 1990 during yearly, monthly, and bimonthly periods. Using a simple analysis of the SAGE results combined with those from all other solar neutrino experiments, we estimate the electron neutrino pp flux that reaches the Earth to be (4.6 +/- 1.1) E10/(cm^2-s). Assuming that neutrinos oscillate to active flavors the pp neutrino flux emitted in the solar fusion reaction is approximately (7.7 +/- 1.8) E10/(cm^2-s), in agreement with the standard solar model calculation of (5.95 +/- 0.06) E10/(cm^2-s).Comment: English translation of article submitted to Russian journal Zh.
