Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) is one of the most damaging pests of Capsicum annuum L. (Solanales: Solanaceae) worldwide. The large genetic diversity of landrace genotypes of C. annuum in several regions of America offers an excellent opportunity to study the factors involved in the resistance response to B. tabaci. This study was carried out to evaluate the oviposition preference and nymphal mortality of B. tabaci in landrace genotypes of C. annuum and to determine whether the physical or chemical characteristics of the leaves influence this response. Oviposition preference varied among genotypes. Low oviposition preference and high nymphal mortality were observed in genotypes Amaxito and Simojovel. Oviposition preference and nymphal mortality showed no significant correlation with leaf size, leaf hardness or trichome density. The chemical composition analyses of leaves of four genotypes with differential response on nymphal mortality showed significant differences in the foliar content of N, phenol, and total flavonoids, but there was no clear trend in the association between the nymphal mortality and chemical composition of leaves.

La guayaba (Psidium guajava L.) es una especie de fruta neotropical. En Colombia su variabilidad morfológica y bioquímica ha sido poco estudiada. En esta investigación se caracterizaron frutos de seis localidades en árboles de guayabo silvestres de la provincia de Sumapaz, estado de Cundinamarca, Colombia con el objetivo de determinar su nivel de variación. Se registraron ocho caracteres cuantitativos y seis cualitativos, se descartaron los últimos por su bajo aporte en la variación de los genotipos. El promedio del peso del fruto (78.16 g), índice de redondez (92 %), sólidos solubles totales (8.62 ºBrix) y contenido de vitamina C (170.82 mg 100 g-1) indicaron que existe potencial en los genotipos silvestres estudiados para su utilización directa. Entre los sitios muestreados se encontró a la accesión de Guavio como sobresaliente por características morfológicas, con peso promedio de fruto de 120.17 g, diámetro longitudinal y transversal de 7.48 y 5.92 cm, respectivamente, aunque el contenido de SST (6.46 ºBrix) o vitamina C (158.85 mg 100 g-1) no fue sobresaliente. Las colectas de los demás sitios mostraron valores desde 8.55 hasta 9.43 ºBrix de sólidos solubles totales, mientras que en contenido de ácido ascórbico los genotipos de Udec mostraron el valor más alto (201.61 mg 100 g-1). En el análisis de agrupamiento por localidades se encontró que la accesión de Guavio conformó un solo grupo y el resto de las accesiones otro. El tipo Guavio no presentó valores notables para los caracteres bioquímicos, pero sí en las características morfológicas; la separación que mostró con respecto al resto de las colectas durante el agrupamiento está centrada en la influencia de las características del fruto. Los resultados indican la existencia de algunos tipos de guayaba silvestre de importancia para uso directo o mejoramiento genético en la provincia de Sumapaz, Colombia.

La producción de maíz de grano amarillo en México es deficitaria, durante 2016 se importaron 12.2 millones de t (FIRA, 2016) para satisfacer la demanda anual, que es superior a 15.3 millones de t, de las cuales 75.7 % del maíz amarillo que se utiliza en México es de uso pecuario, principalmente como fuente de energía para la elaboración de alimentos balanceados. Partiendo de que el aceite del grano de maíz aporta 2.25 veces más energía que el almidón (Alexander, 1988), la utilización de maíz amarillo con alto contenido de aceite (ACA) podría tener impacto significativo en la alimentación pecuaria de rumiantes y monogástricos (bovinos, caprinos, porcinos, aves, entre otros). De acuerdo con Lambert (2000), un maíz ACA debe tener más del 6 % de aceite total en el grano, mientras que un maíz normal tiene de 2.0 a 5.0 %.

Obtener híbridos comerciales competitivos de maíz (Zea mays L.) requiere de estrategias de selección eficientes para mejorar poblaciones y formar progenitores élite. El objetivo de esta investigación fue seleccionar líneas y cruzas de alta aptitud combinatoria general (ACG) y específica (ACE) para rendimiento de grano (RG) y características agronómicas, al combinar las pruebas de mestizos (línea × probador) y cruzas dialélicas. En el ciclo agrícola otoño-invierno 2010-2011 se formaron 144 mestizos con líneas S3 de la población subtropical ST C2 F2, y como probador la población subtropical PABGT-CE C9 F2. Los mestizos se evaluaron en secano en el ciclo agrícola primavera-verano (PV) 2012 en Tlajomulco y Tepatitlán, Jalisco, Peña del Panal, Michoacán, y Santa María del Oro, Nayarit, que cubren un intervalo de 1100 a 1900 m de altitud. En esta prueba se seleccionaron, a través de localidades, nueve mestizos por ACG para RG y tolerancia al acame. Con la semilla remanente de las líneas de mestizos seleccionados, en PV 2015 se formaron cruzas dialélicas. Las cruzas se evaluaron en PV 2016 en las localidades anteriores e Iguala, Guerrero. Las líneas ST C2 F2-21-2-1 y ST C2 F2-29-2-1 sobresalieron en ambas pruebas por su alta ACG para RG, pero la última se eliminó porque en cruzas dialélicas la ACG y ACE para acame fueron positivas y significativas (P ≤ 0.05). La ACE de la cruza ST C2 F2-33-1-1 × ST C2 F2-49-2-1 para RG fue significativa (P ≤ 0.05), y en acame negativa, pero no significativa. El asociar las pruebas de mestizos y cruzas dialélicas permitió seleccionar de una forma más rigurosa líneas con alta ACG y ACE para RG y características agronómicas, además de eliminar líneas antes de formar el sintético y obtener cruzas simples que podrían usarse para formar híbridoscon progenitores élite del otro componente heterótico.

Published: February 2020

La producción de soya [Glycine max (L) Merril.] en el Ecuador se inició en el año 1973 con la siembra de 1227 ha. En la zona centro del sur de la región costa, cuatro de cada 10 agricultores se dedican al cultivo de soya (Moreno y Salvador, 2015). A pesar de que en el país existen variedades mejoradas de soya, el rendimiento nacional promedio en el año 2015 (2040 kg ha-1) fue inferior al de países vecinos (Garcés-Fiallos et al., 2014). Actualmente las variedades recomendadas son INIAP 308 y P-34. La variedad V UG-So-07, generada en la Facultad de Ciencias para el Desarrollo (FACDE) de la Universidad de Guayaquil (UG), es una nueva opción para los productores de soya de la zona centro del sur del litoral ecuatoriano, donde el cultivo se siembra en condiciones de secano.

Romance para un caudillo:
Authors: Inetti Pino Sabina Ximena
Published: February 2020

En el presente trabajo se realiza un acercamiento a la construcción de la figura del caudillo Juan Antonio Lavalleja a través de los poetas Osiris Rodríguez Castillos y Serafín J. García en los años 1953 y 1975. Sus obras literarias seleccionadas, “Romances”, son un tipo de poesía “narrativa y memorial”, que hacen referencia a la identidad nacional del pueblo uruguayo en dos momentos temporales muy específicos de nuestra historia. Esto implica analizar los motivos que llevaron a ambos poetas a la creación de sus obras, como un testimonio de su propia concepción de la realidad, que va desde el ámbito local al nacional.
Un Estado de Clérigos y Familias:
Authors: Chaya Said
Published: February 2020

El Líbano es un “Estado Penetrado”, cuya soberanía se ve asolada por la influencia que los sucesos regionales y globales causan en el interior de las comunidades subnacionales que lo habitan. Al mismo tiempo, los vínculos tribales, fuertemente marcados en su población, sirven de anclaje a terceros Estados que se disputan espacios de poder en este estratégico rincón del Mundo Árabe. El fenómeno no es nuevo. Surgido en 1861, el confesionalismo político promovido por las potencias extranjeras moldeó su sistema de gobierno, primero de la mano del Imperio Otomano y luego de Francia. Este sistema, al día de hoy, presenta importantes continuidades.

ARETÉ E POESIA
Authors: De Almeida Júnior José Benedito
Published: February 2020

O objetivo deste artigo é refletir sobre a reforma educacional realizada por Licurgo em Esparta. A questão principal se dá em torno do enfraquecimento da areté, contra a qual Licurgo criou sua constituição, conhecida como Grande Retra, que restaurou os antigos valores dóricos, mitigando o individualismo crescente e ligando cada espartano ao país. Dentre as leis por ele criadas, as mais importantes foram as educacionais, pois elas mudaram os hábitos e os costumes e, por meio disto, fizeram com que a areté permanecesse no seio do povo espartano por séculos. Por fim, consideramos que a proposta da educação dos guardiães na República de Platão, se inspira na Grande Retra de Licurgo, mas não se limita a ela, introduzindo também uma outra virtude, a temperança, que diferencia e confere um estatuto superior aos guardiões em relação aos guerreiros.
SILENO
Authors: Braga Junior Antonio Djalma , Monteiro Rodrigues dos Santos Ivanildo Luiz
Published: February 2020

O presente artigo propõe uma interpretação inusitada ou, ao menos, mais apurada sobre a figura de Sileno, o qual figura nos mitos sobre o deus do vinho, Dionísio, como companheiro e educador deste ser divino. Isto porque, na tradição e lendas a personagem Sileno, salvo rara exceção, passa quase desapercebida em seu caráter educador.  Friedrich Nietzsche (1844-1900), em sua obra, O nascimento da tragédia, configura uma excelente exceção, quando dedica uma parte importante desta sua obra para falar da Sabedoria de Sileno. Tomando o trecho nietzschiano como base, discorremos sobre as personagens que figuram na mitologia dionisíaca, bem como a centralidade do mito de Dionísio. Isto com o intuito em demonstrar que o culto ao deus do vinho passa por todo um processo de adaptação, de modo que se transformar de uma celebração especificamente campestre (qual era no período arcaico), em uma celebração citadina (no período clássico) quando obtém sua entronização junto aos deuses da cidade. Todavia, nosso principal argumento é que a personagem de Sileno, de alguma maneira já indicaria um abrandamento nos hábitos campesinos, preparando assim o terreno para a urbanização do deus do vinho.

Lahan rawa merupakan lahan yang potensial digunakan untuk usaha pertanian, kehutanan dan konservasi sumber air. Para pakar berbeda pendapat mengenai luas lahan rawa di Indonesia. Perkiraan luas lahan rawa ada yang menafsirkan 34 juta hektar, ada juga yang menafsirkan 39,5 juta hektar.Berdasarkan proses pembentukannya, rawa dibedakan menjadi rawa dalam/lebak dan rawa pasang surut. Rawa pasang surut cenderung lebih banyak dikembangkan mengingat proses reklamasi berjalan lebih cepat. Berdasarkan perkiraan bahwa rerata jangkauan pengaruh pasang surut yang 100 km dari muara sungai besar, maka luas lahan yang berpotensi menjadi lahan pasang surut adalah sekitar 25-30 juta hektar. Lahan pasang surut ini umumnya terdapat di pantai-pantai Kalimantan, Sumatera dan Irian Jaya.Sistem reklamasi yang pernah dan masih dilakukan khususnya di Kalimantan Selatan tergantung kondisi tanah dan airnya, ada beberapa kondisi tanah rawa antara lain tanah rawa potensial, sulfat masam dan gambut. Proses reklamasi terus berkembang dengan telah diketemukannya kisaran komposisi senyawa organik dan sifat kimia tanah gambut pada berbagai kedalaman. Diakui terdapat berbagai kendala seperti fisik tanah, kimia tanah danbeberapa kendala lainnya, namun prospek pengelolaan tanah gambut cukup baik untuk tanaman budidaya. Hasil penelitian dan pengalaman menunjukkan bahwa dengan pengelolaan yang tepat dapat diperoleh produktivitas yang cukup tinggi pada tanah gambut.

Authors: Muchemi Anne , Wakonyo Elias Njoroge
Published: February 2020

In order for implementation of change to be executed successfully in any organization, the human capital should, as a matter of necessity, accept and support the change. Change management practices support behavioral and organizational adjustments thus ensuring that change is accommodated and sustained in the organization. The National Police Service (NPS) faces a myriad of challenges today, pushing the Government to embark on a comprehensive transformational programme within the service with the aim of enhancing performance. With these security sector reforms in progress, successful implementation of change is necessary in order for the objectives of the change to be attained.  Crime rate, public safety and efficient utilization of available police resources remain a major concern in the country, pointing out to the fact that the intended level of police performance is yet to be realized. This study purposed to investigate how the practices used to manage change can impact the delivery of services of the National Police Service in the County of Uasin Gishu. It used the descriptive and explanatory research design. Targeted population was 1,055 junior National Police officers in Uasin Gishu County. The sample comprised of 158 respondents. Structured questionnaires were employed as the main tool of data collection.  Descriptive and inferential statistics were used to analyze the data collected. The findings indicate that employee involvement has a significant positive effect on performance of the National Police Service in Uasin Gishu, effective communication has a significant positive effect on performance of the National Police Service in Uasin Gishu and senior management support has a significant positive effect on performance of the National Police Service in Uasin Gishu County. The findings support the chaos theory theoretical foundation that a small change in organizational practices has the ability to result to huge changes in future outcomes. The recommendations are that the National Police service should involve employees in all stages of the reform process in order for successful change management implementation to be realized and improve performance. To ensure successful change implementation in the National Police Service, employees should be given enough time to share their ideas about change and there should also be effective communication on the objectives of the change. The management of the National Police Service should commit to the change process by leading the process and striving to help employees understand how the changes will affect them personally in order to minimize their anxiety and reduce resistance.

Published: February 2020

In this paper, we investigate the two-way communication between two users assisted by a re-configurable intelligent surface (RIS). The scheme that two users communicate simultaneously in the same time slot over Rayleigh fading channels is considered. The channels between the two users and RIS can either be reciprocal or non-reciprocal. For reciprocal channels, we determine the optimal phases at the RIS to maximize the signal-to-interference-plus-noise ratio (SINR). We then derive exact closed-form expressions for the outage probability and spectral efficiency for single-element RIS. By capitalizing the insights obtained from the single-element analysis, we introduce a gamma approximation to model the product of Rayleigh random variables which is useful for the evaluation of the performance metrics in multiple-element RIS. Asymptotic analysis shows that the outage decreases at $\left(\log(\rho)/\rho\right)^L$ rate where $L$ is the number of elements, whereas the spectral efficiency increases at $\log(\rho)$ rate at large average SINR $\rho$. For non-reciprocal channels, the minimum user SINR is targeted to be maximized. For single-element RIS, closed-form solutions are derived whereas for multiple-element RIS the problem turns out to be non-convex. The latter is relaxed to be a semidefinite programming problem, whose optimal solution is achievable and serves as a sub-optimal solution.
Secession and Referendum
Authors: Landi Giulia
Published: February 2020

The book focuses on current developments on territorial changes in International law. The study inquiries about whether according to international law, the referendum is a sufficient or a necessary condition for secession, or both. Through main “cases study”, the book finds that there is no sufficient practice and opinio juris to support the existence of an international rule according to which the referendum is a sufficient element to legitimize the birth of a new entity. Nevertheless, there are at least some elements supporting the view that the referendum is becoming a necessary tool in the process for secession, provided that it complies with certain procedural standards.

In the Republic of Bashkortostan, in the greenhouse of the year-round operation of the experimental farm of the state-run vocational training school "Ufa forestry-technical school" (Limonary in Ufa city), tropical and subtropical fruit crops have been cultivated for many years. The farm constantly monitors the agrochemical, physico-chemical, biochemical indicators of soil grounds. The agrochemical characteristics of soils during the cultivation of exotic fruit crops have been studied. For fertilizing all cultivated plants of the farm, organic and mineral macro- and micronutrient fertilizers are regularly added at regular intervals. When using fertilizers, the need for nutrient elements of crops is taken into account for successful growth and fruiting by periods of growth and agrochemical data. The study presents a comparative characteristic of soil grounds for 2016 and 2018, which shows: humus content, mobile forms of P2O5 and K2O, mineral forms of nitrogen, pH (salt). The results of agrochemical surveys allow you to adjust the dose of fertilizers for the cultivation of major crops, planting material and for the formation of the crop.

Published: February 2020

When optimizing the relief at the top of the trapezoidal sulfide-containing mine dump, young soil (embryozem) was formed as a result of abio- and biotic factors. In parallel with the formation of embryozems, primary succession processes are developing. As a result, the species composition of vegetation, the staging and intensity of progressive succession were studied depending on the mesorelief of dumps in accordance with the weathering and soil formation processes developing over time. The properties and indicators of young soil in depressions and sulfide rock (control) 25 years after the completion of the dumping of the rock pile were studied. As a result of optimization at the top of the dump, the processes of formation of embryozems in the depressions are significantly accelerated.

Published: February 2020

The aim of the research was to study the influence of weather and climatic environmental factors on the formation of the apricot productivity of various origins. The objects of research were 45 apricot cultivars planted on the collection area in the Nikitsky Botanical Gardens. Phenological observations, yield accepting and determination of plant productivity of different apricot cultivars were done in accordance with generally accepted methods. When analyzing the data of phenological observations during the past 13 years due to climate change, acceleration of flowering and ripening have not been identified. The excess of monthly average precipitation with low monthly average air temperatures leads to a delay of the beginning of flowering of apricot plants by 1-3 weeks. The excess of monthly average air temperature during the period of formation (April-May) and fruit ripening (June-July), as well as a significant decrease in the amount of precipitation relative to their long-term average, accelerates the fruit ripening period. For the studied cultivars, it ranged from 1 to 3 weeks, in comparison with long-term data. Apricot cultivars and forms that better adapted to new growing conditions and have several valuable characteristics were selected: Large Early, Bucuria, Magister, Mandule Kajszi, Sanatate, Stokk, Ketch-Pshar (early or late ripening is combined with high yield; later flowering is combined with early or late fruit ripening). They are of interest for production testing, amateur gardeners and breeders.

Authors: Braunfeld Samuel , Simon Pierre
Published: February 2020

We classify the homogeneous finite-dimensional permutation structures, i.e. homogeneous structures in a language of finitely many linear orders, giving a nearly complete answer to a question of Cameron, and confirming the classification conjectured by the first author. The primitive case was proven by the second author using model-theoretic methods, and those methods continue to appear here.

Published: February 2020

A geometric construction of one-factorisations of complete graphs $K_{q(q-1)}$ is provided for the case when either $q=2^d +1$ is a Fermat prime, or $q=9$. This construction uses the affine group $\mathrm{AGL}(1,q)$, points and ovals in the Desarguesian plane $\mathrm{PG}(2,q^{2})$ to produce one-factorisations of the complete graph $K_{q(q-1)}$.
