ДИФФЕРЕНЦИРОВАННЫЙ ПОДХОД КАК ФАКТОР РАЗВИТИЯ ПРОФЕССИОНАЛЬНО-КОММУНИКАТИВНОЙ КОМПЕТЕНЦИИ СТУДЕНТОВ
Dynamically developing world has caused fundamental changes in the field of education, so there come new trends in the implementation of traditional approaches and new aspects in education sphere, in particular in the context of the formation of educational strategies in solving urgent problems of creative realization of students’ personal potential. The relevance of the implementation of the differentiated approach within the educational system in the modernization of Russian education at the present stage is explained by the fact that it makes it possible, on the one hand, to adapt the educational system to the levels of training, students’ individual characteristics and interests, on the other hand – to formulate a desire for self-education, development of the professional competence of future specialists. The differentiated approach in higher education is aimed at overcoming the contradictions between the level of requirements in educational and professional activities and the real possibilities of each student. The implementation of this approach involves updating the content and professional components, taking into account the characteristics of each student these are individual, age and professional. The main purpose of the study was to determine the efficient criteria and indicators on the implementation of the differentiated approach to students that is to their communicative competence, knowledge of foreign language professional terminology, orientation in cognitive professional and communicative values and the nature of a person’s focus on these values. The results of the study showed that in the process of students professional education the differentiated approach performs the following functions: it is a means of development of an individual personality and future student’s creative potential; it affects the personal and professional adaptation of a future student in society; it contributes to the effective formation of conditions for resourceful professional self-realization of a future student.El desarrollo dinámico del mundo ha provocado cambios fundamentales en el campo de la educación, por lo que surgen nuevas tendencias en la implementación de enfoques tradicionales y nuevos aspectos en el ámbito de la educación, en particular en el contexto de la formación de estrategias educativas para resolver los problemas urgentes de la realización creativa de El potencial personal de los estudiantes. La relevancia de la implementación del enfoque diferenciado dentro del sistema educativo en la modernización de la educación rusa en la etapa actual se explica por el hecho de que hace posible, por un lado, adaptar el sistema educativo a los niveles de capacitación, Las características e intereses individuales de los estudiantes, por otro lado, para formular un deseo de autoeducación, el desarrollo de la competencia profesional de futuros especialistas. El enfoque diferenciado en la educación superior tiene como objetivo superar las contradicciones entre el nivel de requisitos en las actividades educativas y profesionales y las posibilidades reales de cada estudiante. La implementación de este enfoque implica actualizar el contenido y los componentes profesionales, teniendo en cuenta las características de cada estudiante: individual, de edad y profesional. El objetivo principal del estudio fue determinar los criterios e indicadores eficientes sobre la implementación del enfoque diferenciado para los estudiantes, es decir, su competencia comunicativa, el conocimiento de la terminología profesional en idiomas extranjeros, la orientación en los valores cognitivos profesionales y comunicativos y la naturaleza de la persona. centrarse en estos valores. Los resultados del estudio mostraron que en el proceso de educación profesional de los estudiantes, el enfoque diferenciado realiza las siguientes funciones: es un medio de desarrollo de una personalidad individual y el potencial creativo del futuro estudiante; Afecta la adaptación personal y profesional de un futuro alumno de la sociedad; contribuye a la formación efectiva de condiciones para la autorrealización profesional ingeniosa de un futuro estudiante.Динамично развивающийся мир вызвал кардинальные изменения в сфере образования, в связи с чем появились новые тенденции в осуществлении традиционных подходов и возникли новые аспекты, в частности в контексте формирования образовательных стратегий в решении насущных задач творческой реализации личностного потенциала студентов. Актуальность реализации дифференцированного подхода образовательной системы в условиях модернизации российского образования на современном этапе объясняется тем, что она дает возможность, с одной стороны, адаптировать образовательную систему к уровням подготовки, индивидуальным особенностям студентов, их интересам, а с другой стороны – сформулировать стремление к самообразованию, развитию профессиональной компетенции будущих специалистов. Дифференцированный подход в высшем образовании направлен на преодоление противоречий между уровнем требований в учебно-профессиональной деятельности и реальными возможностями каждого студента. Осуществление названного подхода предполагает обновление содержательного и профессионального компонентов с учетом особенностей каждого студента: индивидуальных, возрастных, профессиональных. Основная цель исследования состояла в определении критериев и показателей результативности в осуществлении дифференцированного подхода к студентам: коммуникативная компетенция, владение иноязычной профессиональной терминологией, ориентация в познавательных профессионально-коммуникативных ценностях, характер направленности личности на профессионально-коммуникативные ценности. Результаты исследования показали, что в процессе профессионального образования студентов дифференцированный подход выполняет следующие функции: является средством развития индивидуальной личности и развития творческого потенциала будущего студента; оказывает воздействие на личностную и профессиональную адаптацию будущего студента в обществе; способствует эффективному созданию условия для творческой профессиональной самореализации будущего студента
Passive mode locking of a Tm,Ho:KY(WO4)(2) laser around 2 μm
We report the first demonstration, to our knowledge, of passive mode locking in a Tm3+, Ho3+-codoped KYWO42 laser operating in the 2000-2060 nm spectral region. An InGaAsSb-based quantum well semiconductor saturable absorber mirror is used for the initiation and stabilization of the ultrashort pulse generation. Pulses as short as 3.3 ps were generated at 2057 nm with average output powers up to 315 mW at a pulse repetition frequency of 132 MHz for 1.15 W of absorbed pump power at 802 nm from a Ti:sapphire laser
Investigation of double beta decay with the NEMO-3 detector
The double beta decay experiment NEMO~3 has been taking data since February
2003. The aim of this experiment is to search for neutrinoless
() decay and investigate two neutrino double beta decay in
seven different isotopically enriched samples (Mo, Se,
Ca, Zr, Cd, Te and Nd). After analysis of
the data corresponding to 3.75 y, no evidence for decay in the
Mo and Se samples was found. The half-life limits at the 90%
C.L. are y and y, respectively.
Additionally for decay the following limits at the 90% C.L.
were obtained, y for Ca, y
for Zr and y for Nd. The
decay half-life values were precisely measured for all investigated isotopes.Comment: 12 pages, 4 figures, 5 tables; talk at conference on "Fundamental

Increased Sensitivity to Possible Muonium to Antimuonium Conversion
A new experimental search for muonium-antimuonium conversion was conducted at
the Paul Scherrer Institute, Villigen, Switzerland. The preliminary analysis
yielded one event fulfilling all required criteria at an expected background of
1.7(2) events due to accidental coincidences. An upper limit for the conversion
probability in 0.1 T magnetic field is extracted as (90%
CL).Comment: 2 figure

Maximum output power of 16 mW with slope efficiency of 64% is achieved at 1606 nm under direct in-band pumping by a diode-pump Er,Yb-laser at 1522 nm
Technical design and performance of the NEMO3 detector
The development of the NEMO3 detector, which is now running in the Frejus
Underground Laboratory (L.S.M. Laboratoire Souterrain de Modane), was begun
more than ten years ago. The NEMO3 detector uses a tracking-calorimeter
technique in order to investigate double beta decay processes for several
isotopes. The technical description of the detector is followed by the
presentation of its performance.Comment: Preprint submitted to Nucl. Instrum. Methods A Corresponding author:
