Durante o ano agrícola 1983/84, em condições de casa de vegetação, estudou-se em quatro experimentos a preferência para alimentação de adultos de Diphaulaca viridipennis Clark, 1865, em dois cultivares e nove linhagens de soja. Três experimentos constituíram-se em testes tipo livre chance de escolha: no primeiro, a linhagem PI 227687 apresentou perda de área foliar menor que os demais tratamentos ('Santa Rosa', 'IAC-8', PI 171451 e PI 229358). No segundo e no terceiro experimento, em que se manteve PI 227687 e 'Santa Rosa' como, respectivamente, padrão de resistência e suscetibilidade, as linhagens comparadas (PI 274453, IAC 78-2318, IAC 79-1823, IAC 80-1177, IAC 80-596-2 e D 72-9601-1) exibiram danos foliares intermediários entre esses padrões. O quarto experimento constou de um teste sem chance de escolha envolvendo o tratamento menos danificado nos três experimentos iniciais, PI 227687, e o mais suscetível, 'Santa Rosa'; as porcentagens médias de área foliar comida não diferiram entre os dois materiais, indicando que a resistência observada na linhagem PI 227687 não se mantém sob condições de obrigatoriedade de alimentação por adultos de D. viridipennis.

Penelitian ini bertujuan untuk mengetahui perbandingan fenomena El Nino 2015/16 dan 1997/98 dari segi indeks dan dampak keduanya terhadap curah hujan di Provinsi Bali - Indonesia. Metode analisis yang digunakan berupa metode Korelasi Pearson dan statistik deskriptif terhadap data Indeks Nino 3.4 yang dikonversi menjadi Oceanic Nino Index (ONI) dan data curah hujan bulanan di 22 titik penakar hujan Provinsi Bali. Hasil penelitian menunjukan El Nino 2015/16 (indeks tertinggi 2.37) sedikit lebih kuat daripada El Nino 1997/98 (indeks tertinggi 2.33). Berdasarkan siklus hidupnya, El Nino 2015/16 lebih lama bertahan dibandingkan dengan El Nino 1997/98. Hubungan antara El Nino dengan curah hujan Bali diketahui lebih kuat pada periode September-Oktober-Nopember (SON) dibandingkan dengan periode Desember–Januari–Februari (DJF). Kemudian setelah dilakukan perbandingan antara kedua kejadian El Nino Kuat tersebut, ternyata dampak penurunan curah hujan di Provinsi Bali saat El Nino Kuat 2015/16 (-6% s/d -46%) tidak separah dampak penurunan curah hujan saat fenomena El Nino Kuat 1997/98 (-18% s/d -72%)

AbstractWe consider a derivation of the hierarchy of correlators of ordered exponentials directly from the Lipatov’s effective action (Lipatov in Nucl Phys B 452:369, 1995; Phys Rep 286:131, 1997; Subnucl Ser 49:131, 2013; Int J Mod Phys Conf Ser 39: 1560082, 2015; Int J Mod Phys A 31(28/29):1645011, 2016; EPJ Web Conf 125: 01010, 2016) formulated in terms of interacting ordered exponentials (Bondarenko and Zubkov in Eur Phys J C 78(8), 617 2018; Bondarenko et al. in Eur Phys J C 81(7):61, 2021). The derivation of the Balitsky equation (Balitsky in Nucl Phys B 463:99, 1996; Phys Rev D 60:014020, 1999; At the frontier of particle physics, vol. 2, p. 1237–1342; Nucl Phys B 629:290, 2002; Phys Rev D 72:074027, 2005) from the hierarchy is discussed as well as the way the sub-leading eikonal corrections to the Balitsky equation arise from the transverse field contribution and sub-leading eikonal corrections to the quark propagator. We outline other possible applications of the proposed calculation scheme.

We present convergent close-coupling (CCC) calculations of electron-impact dissociation of vibrationally-excited molecular hydrogen into neutral fragments. This work follows from our previous results for dissociation of molecular hydrogen in the ground vibrational level [Scarlett et al., Eur. Phys. J. D 72, 34 (2018)], which were obtained from calculations performed in a spherical coordinate system. The present calculations, performed utilizing a spheroidal formulation of the molecular CCC method, reproduce the previous dissociation cross sections for the ground vibrational level, while allowing the extension to scattering on excited levels.

Abstract Objective To compare neurocognitive scores between the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) Quick Test (QT) and Online Versions in non-concussed high school athletes. Methods A sample of 47 high school athletes completed the ImPACT Online Version pre-season and the ImPACT QT approximately 3 months later. Paired sample t-tests and Pearson’s correlations examined differences and relationships between the ImPACT batteries. Results The ImPACT QT scores were significantly higher for performance on the Three Letters: Average Counted (p < .001, d = .88), Three Letters: Average Counted Correctly (p < .001, d = .80), and Symbol Match: Correct RT Visible (p < .001, d = .72), and Symbol Match: Correct RT Hidden (p = .002, d = .50) subtests. There were significant relationships for Three Letters: Average Counted (r = .85, p < .001), Three Letters: Average Counted Correctly (r = .82, p < .001), and Symbol Match: Total Correct Hidden (r = .40, p = .006) subtests. Conclusions Post-injury evaluation data using ImPACT QT should be compared to normative referenced data, and not to pre-season data from the ImPACT Online Version.

Em condições de campo e de telado, estudou-se o comportamento das seguintes linhagens e cultivares de soja em relação à lagarta-enroladeira, Hedilepta indicata (Fabr., 1775): PI 227687, IAC 73-228, IAC 79-1823, 'Santa Rosa', IAC 80-596-2, 'IAC 12', 'IAC 8', IAC 78-2318, D 72-9601-1, PI 171451, 'IAC São Carlos' e PI 229358, quanto ao número de pontos de ataque do inseto. Tanto no campo como em telado, IAC 73-228 e PI 229358 apresentaram, respectivamente, o menor e o maior valor. Em condições de campo, PI 227687 e IAC 73-228 sofreram as menores perdas de área foliar devidas ao ataque de H. indicata, enquanto 'IAC São Carlos', PI 171451 e PI 229358 se mostraram como os mais suscetíveis. Em outro experimento conduzido em campo, utilizando-se PI 274454, PI 274453, IAC 73-228, 'IAC 12', IAC 80-596-2, 'UFV-1', IAC 78-2318 e 'Paraná', os dois primeiros apresentaram alto nível de resistência ao inseto, superior ao exibido por IAC 73-228, sendo que 'Paraná' teve a maior perda de área foliar. Ainda em condições de campo, em área de seleção de plantas F2 descendentes do cruzamento de 'Paraná' com PI 274453, foram avaliadas, individualmente, plantas quanto à área foliar comida: os resultados obtidos sugerem que a resistência da PI 274453 a H. indicata seja devida a um gene dominante.

Die vorliegende Studie überprüft die Wirksamkeit eines kognitiv-verhaltenstherapeutischen Präventionsprogramms für Kinder mit internalisierenden Symptomen. Eine modifizierte Version der deutschen Bearbeitung des australischen Programms FRIENDS wurde im indizierten Präventionskontext angewendet und unter Verwendung eines Wartelistendesigns mit Eigenkontrollgruppe evaluiert. 81 Kinder (42 Jungen, 39 Mädchen) im Alter von acht bis 12 Jahren nahmen teil. Sowohl das Elternurteil (CBCL), als auch das Selbsturteil der Kinder (SCAS, DIKJ) wurden zur Wirksamkeitsüberprüfung herangezogen. Die Datenerhebungen erfolgten zu drei Zeitpunkten (drei Monate vor Beginn sowie unmittelbar vor und nach der Intervention). Die Ergebnisse sprechen für die Effektivität des Programms; die internalisierenden Symptome der Kinder reduzierten sich während der Intervention signifikant stärker als während der Wartezeit. Mittlere Effektstärken zeigten sich sowohl aus Elternsicht (d = .72), als auch aus Kindersicht (d = .55).

El presente estudio evalúa el efecto de una intervención adaptada del Programa Inteligencia Emocional Plena (PINEP) en adultos que han sufrido la pérdida de un ser querido. La intervención tiene una duración de doce sesiones, de dos horas y media por semana. La muestra está compuesta por 17 adultos de un rango de edad de entre 26 y 71 años (M = 50.59; SD = 14.44). Los participantes que completaron la intervención, muestran una mayor tolerancia al malestar desarrollando habilidades en mindfulness [t(16) = 4.17, d = 1.04, p ≤ .001] y una disminución en ansiedad estado [t(16) = -2.94, d = .72, p = .005], ansiedad rasgo [t(16) = -3.48, d = .78, p ≤ .001] y depresión [t(16) = -3.18, d = .66, p= .003]
