The functional dependence between the value of logistical chains and the cost of the company is established, which reveals the applied nature of creating the value of logistical chains by maximizing the net financial flow in operational and increasing the value of companies in strategic periods.
USE OF THE URBAN LOGIC THEORY WITH DEVELOPMENT PROJECTS MANAGEMENT
Authors: Sakhno Evgen Yuriiovych , Moroz Nataliia Viktorivna , Ponomarenko Serhii Ivanovych
Published: November 2018

Urgency of the research. The study of the methods of economic and financial evaluation of the effectiveness of development projects is an underdeveloped area of economic knowledge, due to the impossibility of predicting the obstacles associated with investments in the future, and the implementation of such projects is most often associated with risk and uncertainty.
Target setting. Therefore, in this case, it is proposed to use fuzzy logic theory, which defines a modern approach to describe business processes that present uncertainty and inaccuracy of the source information.
Actual scientific researches and issues analysis. The question of using the theory of fuzzy logic in the management of development projects is highlighted in the scholarly works of Ukrainian and foreign scholars such as Asai K,
Borisov A. N., Gordienko I. V., Semenenko M. V., Mityushkin Yu. I., Mokin B. I. and others.
Uninvestigated parts of general matters defining. Known studies have shown that classical control methods work quite effectively at fully deterministic control objects and environments, and for systems with incomplete information and high complexity, fuzzy analysis methods that are optimal to be adapted to a modern project management system for constructing an integrated neural network are optimal.
The research objective. The task is to use the fuzzy models to move on to the development of modern management technology with the use of artificial neural networks to integrate the enterprise management system and development projects.
The statement of basic materials. The transition from traditional control systems to systems with fuzzy logic occurs using fuzzy variables. Let's consider the process of neural network modeling in the integration of enterprise management systems and development projects for the construction of a single integrated enterprise management system.
Conclusion. In this paper we propose a methodology for the implementation of investment projects for the implementation of information systems based on fuzzy-plural approach, which allows to take into account qualitative aspects that do not have an exact numerical evaluation.

The Fate of Water at the Electrochemical Interfaces: Electrochemical Behavior of Free Water vs. Coordinating Water

Published: November 2018

The water reduction which produces hydrogen is one key reaction for electrochemical energy storage. While it has been widely studied in traditional aqueous electrolytes for water splitting (electrolyzers), it also plays an important role for batteries. Indeed, the reduction of water at relatively high potential prevents the practical realization of high-voltage aqueous batteries, while water contamination is detrimental for organic batteries electrolytes. Nevertheless, recent studies pointed towards the positive effect of traces of water for Li-air batteries as well as for the formation of solid-electrolyte-interphase. Herein, we provide a detailed understanding of the role of the solvation on water reduction reaction in organic electrolytes. Using electrochemistry, classical molecular dynamics simulations and nuclear magnetic resonance spectroscopy, we were able to demonstrate that 1) the hydrophilicity/hydrophobicity of the species inside the electrochemical double-layer directly controls the reduction of water and 2) water coordinating strong Lewis acids such as Li+ cations is more reactive than “free” water (or non-coordinating) water molecules.
Infinite Dilution Activity Coefficients as Constraints for Force Field Parameterization and Method Development
Authors: Duarte Ramos Matos Guilherme , Calabró Gaetano , Mobley David
Published: November 2018

Molecular simulations see widespread use in calculating various physical properties of interest, with a key goal being predictive molecular design. These simulations, including molecular dynamics (MD) simulations, begin with a underlying energy model or force field and then, based on this model, use simulations to compute properties of interest. However, one of the most significant challenges in molecular dynamics and modeling studies is ensuring that the force field is a good enough approximation of the underlying physics that computed quantities can be used to reproduce experimental properties with the desired level of accuracy. Parameterization of force fields depend on various experimental properties including as much of the chemistry of interest as possible. Physicochemical properties measurable in a relatively straightforward manner are particularly interesting for developers. Such properties can be measured for a relatively diverse chemical set and used to expand the parameterization dataset as needed. Here, we examine infinite dilution activity coefficients (IDACs) which are experimental quantities that can play this role. We retrieved 237 empirical IDACs from NIST's ThermoML, a database of measured thermodynamic properties, and we estimated the corresponding values using solvation free energy calculations. We found that calculated IDAC values correlate strongly with experiment. Specifically, the natural logarithm of calculated and experimental IDAC values shows a Pearson correlation coefficient of 0.85+/-0.02. The calculated IDAC values allow us to identify strengths and potential weaknesses of force field parameters for specific functional groups in solutes and solvents, suggesting these may be a valuable source of data for force field parameterization, capturing some of the same type of information as hydration and solvation free energies and thus potentially providing a useful new source of experimental data.
Dynamic Supramolecular Interaction in Cucurbit[7]uril Host-Guest Complex Enables Autonomous Single Molecule Blinking and Super-Resolution Imaging in Cells and Tissues

Published: November 2018

Synthetic supramolecular host-guest complexes are inherently dynamic as they employ weak and reversible noncovalent interactions for their recognition process. This dynamic behavior allows host-guest chemistry to be employed for various state of the art applications. Herein, we demonstrate the use of the dynamic supramolecular interaction to enable nanoscopic imaging inside cells and tissues. This imaging method exploits repetitive and transient binding of fluorescently labeled hexamethylenediamine (HMD) guest molecule to complementary cucurbit[7]uril (CB[7]) host to obtain stochastic switching between fluorescence ON- and OFF-states. Through connecting CB[7] hosts to targeting ligands (e.g., antibodies and small molecules), we show that this autonomous blinking enables two-dimensional (2D) and 3D super-resolution imaging of proteins in fixed cells and tissues. Finally, we exploited the capability of host-guest molecules to maintain their interaction specificity in the complexity of the live intracellular environment to obtain super-resolution actin imaging in living HeLa cell.
Stable and Reversible Functionalization of the Native Phosphate Groups on Live Cells
Authors: Majumder Joydeb , Chopra Gaurav
Published: November 2018

The ability to label live cell surfaces has many applications ranging from in vivo monitoring of cell populations to diagnostics and use of cells as drugs. Thus far, most reported strategies to label cell surfaces are not broadly applicable or easy to use for any cell type as it has relied on engineering cells with artificial moieties or conjugations that may affect cellular function. We provide a general solution to this long-standing problem by developing two-sided functionalization of the phosphate moieties that are ubiquitous on all cells. We show one application of our chemical strategy as a general-purpose live-cell membrane imaging reagent with long-time stability. Our strategy is broadly applicable to imaging, sensing, drug delivery, bioengineering, diagnostics and cell therapy.
Pollination ecology of Desmodium setigerum (Fabaceae) in Uganda; do big bees do it better?
Authors: Stanley Dara , Otieno Mark , Steijven Karin , Piironen Tiina , Willmer Pat , Nuttman Clive
Published: November 2018

Explosive pollen release is documented in many plant families, including the Fabaceae. Desmodium setigerum E. Mey (Fabaceae) is a perennial herb with single trip explosive pollen release found in eastern Africa, and the unique ability to reverse floral colour change if insufficient pollination has occurred. However, little else is known about the pollination ecology of this species, what visitors can trigger explosive pollen release, and whether bee body size is related to pollination efficiency.  We investigated: 1) the breeding system of D. setigerum, and whether it is pollen limited; 2) whether flowers are visited early in the day allowing sufficient time for a second opportunity for pollination; and 3) what insect species visit D. setigerum and the relative efficacy of different flower visitors in relation to visitor size and pollination success. We found that although self-compatible, D. setigerum requires insect visitation to set seed as explosive pollen release is needed even for selfing. Most flowers are initially visited before 1400h, and by 1800h nearly all flowers have been tripped. Flowers were not pollen limited in this study, and were visited primarily by bees. We observed 16 visiting species, and there was a wide variation (0-404 grains) in the amount of pollen deposited on stigmas. Although almost all bees deposited some pollen, the mean number of pollen grains deposited in a single visit per species was negatively related to body size. However, one particular megachilid species deposited significantly more pollen grains than any other visitor and so is likely an important pollinator of this species. This provides insights into the pollination biology of this unique plant species, and adds to increasing literature on the relationships between bee body size, explosive pollen release and pollination effectiveness.
Inhibition of biochemical terpene pathways in Achillea millefolium flowers differently affects the behavior of bumblebees (Bombus terrestris) and flies (Lucilia sericata)
Authors: Larue-Kontić Anne-Amélie Chloe , Junker Robert R.
Published: November 2018

Floral scents serve multiple functions in the interactions with organisms. Flowers of Achillea millefolium (Asteraceae) emit scent bouquets dominated by terpenoids. These flowers are mainly visited by flies and beetles, whereas bumblebees, common visitors at other Asteraceae, are absent from A. millefolium flowers. In order to test how a reduced mono- and sesquiterpenoid emission affect insect behaviour we inhibited the biochemical pathways towards the production of terpenoids of A. millefolium plants and conducted behavioural choice tests. The inhibition resulted in reduced emission rates of most mono- and sesquiterpenes and thus altered the olfactory phenotype of the flowers. In a flight cage, flies usually chose flowers with a natural scent bouquet, bumblebees clearly preferred flowers treated with inhibitors. These findings confirm that floral scents play a pronounced role in foraging decisions of flower visiting insects and support the notion that responses towards scent are animal species-specific emphasising the role of scents as floral filters.
Pollen Removal and Deposition by Pollen- and Nectar-Collecting Specialist and Generalist Bee Visitors to Iliamna bakeri (Malvaceae)
Authors: Tepedino Vince , Horn Laura Arneson , Durham Susan
Published: November 2018

Up to 60% of the bee species of a region are oligolectic; they collect pollen only from a closely related group of plants though nectar-collecting choices are often broader. Bee specialists are expected to be superior to generalists in gathering pollen from their host plants and perhaps in transferring pollen to host stigmas. We used the oligolege Diadasia nitidifrons and its pollen-host Iliamna bakeri to ask if specialists 1) were more efficient than generalists as pollen-collectors; 2) deposited more pollen on stigmas than generalists; and 3) if pollen-collectors removed and deposited more pollen than did nectar-collectors. We found support for the first and third hypotheses. Diadasia pollen- and nectar-collectors removed more pollen per flower-visit than did their primary generalist competitors (Agapostemon spp.). The superior pollen-gathering efficiency of Diadasia exceeded differences that might be attributed to size: although Agapostemon females are, on average, 12.5% smaller than Diadasia females, pollen-collecting Agapostemon left 22.9% more pollen in flowers than did Diadasia. We found no difference between taxa in time spent foraging on a single flower. Diadasia and Agapostemon pollen-collectors deposited significantly more pollen on I. bakeri stigmas than did nectar-collectors; there was no difference between taxa in pollen deposition. Diadasia was superior to generalists as a pollinator in two ways: Diadasia was 1) a more reliable presence in I. bakeri populations; and 2) always most abundant at I. bakeri flowers. The association between D. nitidifrons and I. bakeri appears to be another example of a highly specialised bee affiliated with an unspecialised host-plant.
Comparative floral ecology of bicolor and concolor morphs of Viola pedata (Violaceae) following controlled burns

Published: November 2018

We compared pollination and seed set of bicolor and concolor morphs in self-incompatible, Viola pedata over two seasons in two populations of unequal sizes.  One population grew on a wooded slope (CR) and the second on an exposed glade (SNR).  Both were burned in 2014. The number of flowers produced by concolor plants at SNR was higher in 2014 while the number of flowering bicolors increased at CR in 2015. Petal temperatures, regardless of site, showed that dark purple, posterior petals of bicolors were consistently warmer than their own mauve-lilac, anterior (lip) petals and the all mauve petals of concolors. Major pollen vectors were female bees (Andrenidae, Apidae and Halictidae) but polylectic, Andrena carlinii dominated both sites.  Bees foraged on flowers upside down or right side up but neither mode correlated with either morph. Bees foraged preferentially on concolor at both sites.  Pistils containing pollen tubes were higher in concolor pistils at both sites with a marginally greater number of  tubes penetrating concolor ovules regardless of site or year.  While both populations produced more seeds in 2014 SNR plants always produced more seeds than CR plants.  The increasing numbers of bicolor plants at CR in 2015 suggested that bicolors may equal or outnumber concolors when dark petals offer additional warmth to ectothermic pollinators in a shady (cooler) forest vs. an open, sunny glade. Subtle environmental factors may give a floral trait a selective advantage influencing fitness in an unbalanced polymorphism persisting in localized populations.
Criticism mismatched: Response to de Keyzer et al. 2016
Authors: Miller-Struttmann Nicole , Geib Jennifer C. , Galen Candace
Published: November 2018

In a recent paper, we reported on the evolution of shorter tongues in two alpine bumble bee species in response to climate-induced flower deficits. De Keyzer et al. concede that tongue lengths have decreased but criticize the level of support for our claims.  Here, we address the alternative mechanisms they proposed, highlight evidence presented in the supplementary material, and elaborate on the support for our claims in the literature.  De Keyzer et al.’s criticisms reflect concerns about the misrepresentation of our work in the popular press. To clarify, we do not imply that evolutionary rescue is necessarily a prudent conservation strategy; we illustrate that remote bumble bee populations buffered from other environmental stressors have undergone an adaptive evolutionary response to dwindling resources under climate change.

Published: November 2018

Pemberian ART (Anti Retroviral Therapy) lebih dini pada level CD4 yang lebih tinggi diyakini memberikan outcome yang lebih baik. Penelitian bertujuan mengetahui adanya perbedaan outcome dan tingkat kadar CD4 berdasarkan periode waktu inisiasi awal ART pada penderita HIV positif. Penelitian menggunakan rancangan kohort retrospektif, menggunakan data sekunder untuk melihat perbedaan outcome (CD4, status mortalitas, morbiditas, lost to follow up) pasien berdasarkan periode waktu inisiasi ART. Populasi penelitian adalah seluruh pasien HIV-positif yang sedang atau sudah menjalani ART di Kota Denpasar. Sebanyak 312 pasien diikutkan dalam penelitian ini sesuai kriteria. Hasil penelitian menunjukkan bahwa proporsi subjek yang mengalami kenaikan CD4 hanya 0-99sel/mm3 cenderung lebih besar pada kelompok yang memulai ART lebih dari 12 minggu dibandingkan pada kelompok yang memulai ART 12 minggu ke bawah (44.7% vs 36.7%). Begitu pula sebaliknya, proporsi subjek yang mengalami kenaikan CD4 ≥100 sel/mm3 lebih besar pada kelompok inisiasi ART ≤12 minggu (73.3% vs 55.3%) p=0.046. Proporsi subjek yang meninggal dan lost to follow up lebih besar pada kelompok subjek yang memulai ART lebih dari 12 minggu dari pada sebaliknya (berturut-turut 11% dan 24.2% vs 5% dan 12.7%, p=0.003). Perbedaan signifikan juga terlihat, proporsi subjek yang masih memakai ART lebih besar pada kelompok subjek yang melakukan inisiasi ART ≤12 minggu (64.8% vs 82.4%, p=0.003).
Trauma y desarraigo en A Pale View of Hills, de Kazuo Ishiguro
Authors: Jacovkis Vera Helena
Published: November 2018

In A Pale View of Hills, Kazuo Ishiguroʼs first novel, the main character and narrator Etsuko remembers a summer in Japan after the Second World War. Migration and the possibility of rebuilding their lives in a different place become a matter of discussion in that period. The purpose of this article is to explore through textual analysis how the novel presents an experience of war in visual terms. Sight becomes the frame for war experience, and therefore the notion of ʻwitness’ becomes central. The narrator takes a position between being a victim and being a witness, showing the difficulties of telling traumatic experiences such as war, the atomic bomb, and its consequences.
Mirar el exilio desde el exilio
Authors: Magnani Ilaria
Published: November 2018

The essay intends to act as a reading of the novel Mother tongue of the Argentinean author María Teresa Andruetto, based – as requested by the call – on the reflections of Edward Said. More specifically, I would like to consider the influence that, in the novel, the voluntary exile of the daughter has in the delayed look that she lays on the forced exile of the deceased mother. At the same time, I am interested in considering the impact on the narrative of the Patagonian geographical context, in which events take place, and the myth of the wild – salvific land that accompanies it.

The History of Politics in Angola
Authors: Camba Tomás Fernando
Published: November 2018

The political, economic and social instabilities of the African countries have been seen as one of the biggest challenges to be overcome in the current days. Today, the lack of economic and social freedom is the great problem that makes the weak effort of the African politicians on consolidating the political and economic systems in permanent crisis, even more vulnerable. We attempt to understand the reasons of the increasing levels of bribery of the public and private institutions besides the deficit of a political ethics and other corrosive factors of the African nations that make it a continent with a high level of vulnerability. So, we task ourselves to draft a historic line of the political thought of one of the most promising countries of the African continent: Angola. This is achieved through the use of historic sources that chain the main political events of the history of Angola that led to the independence and that succeeded. It is concluded that the state intervention based on ideas socialist / communist ideas has been, as theoretically proved by the Austrian School, harmful to the socio-economic development of the African country and it is suggested a review to such intervention to be completed in a future paper.

Objetivou-se avaliar a relação entre os índices reprodutivos (intervalo entre parto e período de serviço) e a produção de leite (produção por lactação, duração da lactação e persistência de lactação) em vacas mestiças de média-baixa e média produção. Foram utilizados dados de um controle leiteiro de 40 vacas mestiças, Holandês- Gir, de diferentes composições genéticas, todas multíparas (4 a 10 o número de lactações), no período de maio de 2015 a maio de 2016. Os animais foram divididos em dois grupos: Grupo 1 constituído de vacas de produção diária menor que 15 litros de leite, e Grupo 2 constituído de vacas com produção diária entre 15 e 20 litros de leite, sendo essa divisão fundamentada no princípio de que vacas de alta produção demoram mais a retornar ao estro e consequentemente pode influenciar na fertilidade. Os indicadores zootécnicos analisados foram: duração da lactação, média de produção diária, produção por lactação, intervalo entre parto (IEP) e período de serviço. Apenas o IEP não diferiu (P>0,05) entre os grupos. A eficiência reprodutiva das vacas de média produção (15 até 20 litros/dia) não foi influenciada pela produção de leite, sendo mais viável ao produtor além de apresentar maior persistência de lactação.

O referido experimento foi desenvolvido com o objetivo de avaliar os efeitos de diferentes dosagens de silício via aplicação foliar em plantas de híbridos de Tomate irrigadas com água salina, em condições de cultivo protegido. Utilizou-se o delineamento experimental inteiramente casualizado, com uma testemunha e cinco concentrações de silicato de potássio (K2SiO3), e 10 repetições cada. As avaliações ocorreram aos 20, 45, 75 e 90 DAT para: alturas de plantas; diâmetro do caule; número de folhas e porcentagem de clorofila e aos 27, 47, 79 e 87 DAT: número de flores e número de cachos. Também foram avaliados comprimento, volume e peso seco do sistema radicular, número total de frutos por planta, peso total de frutos, diâmetros longitudinal e vertical dos frutos. Os resultados obtidos foram submetidos à análise de variância (F ≤ 0,05), e as médias submetidas ao teste de Tukey (P ≤ 0,05) e análise de regressão polinomial. Para as variáveis altura da planta, volume, peso fresco, peso seco das raízes, a melhor dosagem foi a de 25 ml.L-1 de K2SiO3, enquanto que a dosagem de 75 ml.L-1 de K2SiO3 proporcionou melhores resultados para matéria seca das raízes, número de folhas e de flores.

O balanço hídrico é uma ferramenta de caraterização temporal da dinâmica de água no solo de determinada região. Objetivou-se estimar o balanço hídrico climático e a classificação do clima do município de Turiaçu-MA. Foram utilizados séries de dados históricos entre os anos de 1961 a 2016, de precipitação pluviométrica e temperatura mensais, sendo excluídos dados omitidos. Para o cálculo do balanço hídrico climatológico, foi adotado o valor de 100 mm para a capacidade de água disponível (CAD). A classificação climática foi obtida por meio dos valores do índice hídrico (Ih), índice de aridez (Ia) e índice de umidade (Iu). A evapotranspiração potencial atingiu valores médios anuais de 1765,3 mm. A deficiência hídrica total anual verificada foi de 535,3mm, distribuído em sua totalidade ao longo do período de estiagem da região (agosto a dezembro). A fórmula climática obtida foi B1sA’a’, isto é, clima úmido, Megatérmico, com deficiência hídrica moderada no verão e 26,6 % da evapotranspiração anual concentrada no trimestre mais quente do ano.

Objetivou-se avaliar a germinação de sementes de mostarda em função da temperatura e a emergência e o crescimento das mudas sob diferentes recipientes e substratos. O experimento foi conduzido na Universidade Federal do Ceará, Fortaleza-CE, onde foi dividido em dois ensaios. No primeiro, avaliou-se as temperaturas (15, 20, 25, 30, 35 e 40 °C), sob delineamento inteiramente casualizado e com quatro repetições. No segundo, usou-se o delineamento de blocos casualizados, com quatro repetições e sob esquema de parcelas subdividida para a emergência e subsubdividida para o crescimento das mudas. Nas parcelas, avaliou-se os recipientes (450, 200 e 162 células), nas subparcelas, os substratos [S1 - 100% húmus de minhoca (HM); S2 - 60% HM, 20% fibra de coco (FC) e 20% de vermiculita (VERM); e S3 - 80% (HM), 10% (FC) e 10% (VERM) e nas subsubparcelas, as datas de avaliação (25, 32 e 42 dias após a semeadura). As temperaturas de 23,3 e 26,6ºC proporcionaram o maior percentual e velocidade de germinação das sementes, respectivamente. A emergência foi favorecida pelo substrato S3, enquanto que o maior crescimento das mudas foi obtido no recipiente de 162 células, preenchido com o substrato S1 e aos 42 dias após a semeadura.

Esse estudo propõe a exploração de novos horizontes no que diz respeito à piscicultura. Nesse contexto, foi desenvolvida uma pesquisa na propriedade rural Sítio Gurjaú, localizada no município de Coronel Ezequiel – RN, no período de agosto de 2016 a julho de 2017. O presente estudo teve como objetivos avaliar os parâmetros físicos e químicos da água em tanques escavados e o reflexo que estas variáveis exercem sobre o desempenho produtivo da tilápia Oreochromis niloticus (Linhagem Chitralada). Sendo assim, ocorreram visitas quinzenais, sendo possível coletar água e submetê-las a estudos físicos e químicos por meio do Kit Acqua Supre, oxímetro e disco de Secchi, sendo estas variáveis: temperatura, transparência, alcalinidade, dureza, oxigênio dissolvido (OD), amônia total, nitrito, gás carbônico, e potencial hidrogeniônico (pH). Os dados aferidos foram submetidos á estatística descritiva, permitindo observar a média dos valores correspondentes. Resultados relacionados aos parâmetros hidrológicos, como OD na água alcançaram valores entre 6,92 a 9,63 mg/L; gás carbônico dissolvido na água com uma média de 17,02 mg/L; nitrito, correspondo a média de 0,2 mg/L e amônia total, com média de 2,09 mg/L. Esse estudo tem importância econômica na exploração da tilapicultura como alternativa, abrindo possibilidade para a sustentabilidade e o agronegócio.

Objetivou-se avaliar a qualidade físico-química e microbiológica do leite de cabra produzido em propriedades de Petrolina-PE.   Para as análises físico-químicas utilizou-se equipamento Master Classic Complete AKSO®, com exceção da acidez, utilizando-se o método Dornic. Foram realizadas análises de contagem de bactérias aeróbias mesófilas (BAM), número mais provável de coliformes (NMP) totais e termotolerantes. Três amostras apresentaram inadequação quanto ao teor de acidez, nove para índice crioscópico e três para gordura conforme valores estabelecidos pela legislação. Densidade, proteína, SNG, cinzas e lactose apresentaram médias de 1029,65 (g/cm3); 3,22; 8,71; 0,71 e; 4,80 (g/100g), respectivamente. BAM variaram de 5,3x10² a 5,3x105, onde apenas a propriedade cinco apresentou valor superior ao permitido. Foram identificados coliformes totais em todas as amostras e coliformes termotolerantes apenas nas propriedades um e dois. As amostras de leite de cabras, que apresentaram-se fora do estabelecido pela legislação, denotam a necessidade de maior controle por parte dos produtores, servindo também como alerta às autoridades sanitárias.
