O semiárido nordestino é caracterizado historicamente como uma região onde o conflito pelo acesso e uso da água sempre esteve presente no cotidiano de sua população. Por uma série de fatores como: escassez hídrica crônica gerada pelo padrão climático da região, estruturação fundiária que privilegia apenas o desenvolvimento econômico dos grandes proprietários de terra e seus projetos agropecuários, ineficiência do estado em promover políticas públicas de gestão e conservação dos recursos hídricos, e intervenções pontuais de mitigação dos efeitos da seca, apenas em episódios extremos de déficit hídrico, causando pouca efetividade na solução do quadro de miséria e abandono da população. Diante do quadro histórico e socioeconômico de grandes prejuízos e degradação ambiental ocasionados pela seca e pela má gestão dos recursos hídricos no Ceará. Muitas pesquisas e projetos com o intuito de compreender o regime hidroclimático dos seus municípios surgiram como forma de entender as potencialidades e limitações das diferentes áreas, e dessa forma auxiliar a criação e a manutenção de políticas públicas de desenvolvimento socioeconômico e preservação ambiental. Diante deste contexto a pesquisa se propõe a realizar o balanço hídrico da Área de Influência do Açude Castanhão -CE, como uma ferramenta de gerenciamento e planejamento de recursos hídricos.Palavras-chave :Balanço Hídrico; Gestão; Recursos hídricos. ABSTRACTThe Northeastern semi-arid region is historically characterized as a region where conflict over access and use of water has always been present in the daily life of its population. For a series of factors such as: chronic water shortage generated by the region's climatic pattern, land tenure structuring that privileges only the economic development of large landowners and their agricultural projects, inefficiency of the state in promoting public policies for the management and conservation of water resources, and occasional interventions to mitigate the effects of drought, only in extreme episodes of water deficit, causing little effectiveness in solving the misery and abandonment of the population. In view of the historical and socioeconomic picture of great damages and environmental degradation caused by drought and the poor management of water resources in Ceará. Many researches and projects aimed at understanding the hydroclimatic regime of their municipalities have emerged as a way of understanding the potentialities and limitations of the different areas, and in this way help to create and maintain public policies for socioeconomic development and environmental preservation. In this context, the research proposes to carry out the water balance of the Area of Influence of the Castanhão-EC, as a tool for management and planning of water resources.Keywords: Hydric balance; Management; Water resources

QUANTUM-CHEMICAL STUDY OF INTERACTION 1,2-ETHANEDITHIOL WITH 1,3-DICHLOROBUTENE-2 IN THE SYSTEM HYDRASINEHYDRATEKOH
Authors: Chirkina Elena 
Published: October 2019

According to the results of quantum-chemical studies in the framework of the theory
of functional density of the electron density using the B3LYP / 6-311 ++ G (d, p) method, a theoretical
mechanism of the reaction of 1,3-dichlorobutene-2 with 1,2-ethanedithiol in the hydrazine hydrateKOH system has been proposed. It has been shown that this interaction proceeds sequentially in several stages, including the nucleophilic substitution of the chlorine atom of the sp3 hybridized carbon
atom to the sulfur atom with the formation of a monosubstitution product (SN2 mechanism), which under the action of alkali undergoes deprotonation of the methylene group to form an allyl carbanion .
The resulting carbanion, due to the migration of hydrogen and the removal of chlorine, is converted
into an allene derivative, which as a result of the intramolecular nucleophilic attack of the free
thiolate group on the central carbon atom of the allene fragment closes into the final dithian cycle.

Incorporation of doxorubicin in different polymer nanoparticles and their anticancer activity
Authors: Pieper Sebastian , Onafuye Hannah , Mulac Dennis , Cinatl Jindrich , Wass Mark N , Michaelis Martin , Langer Klaus 
Published: October 2019

Background: Nanoparticles are under investigation as carrier systems for anticancer drugs. The expression of efflux transporters such as the ATP-binding cassette (ABC) transporter ABCB1 is an important resistance mechanism in therapy-refractory cancer cells. Drug encapsulation into nanoparticles has been shown to bypass efflux-mediated drug resistance, but there are also conflicting results. To investigate whether easy-to-prepare nanoparticles made of well-tolerated polymers may circumvent transporter-mediated drug efflux, we prepared poly(lactic-co-glycolic acid) (PLGA), polylactic acid (PLA), and PEGylated PLGA (PLGA-PEG) nanoparticles loaded with the ABCB1 substrate doxorubicin by solvent displacement and emulsion diffusion approaches and assessed their anticancer efficiency in neuroblastoma cells, including ABCB1-expressing cell lines, in comparison to doxorubicin solution.Results: The resulting nanoparticles covered a size range between 73 and 246 nm. PLGA-PEG nanoparticle preparation by solvent displacement led to the smallest nanoparticles. In PLGA nanoparticles, the drug load could be optimised using solvent displacement at pH 7 reaching 53 µg doxorubicin/mg nanoparticle. These PLGA nanoparticles displayed sustained doxorubicin release kinetics compared to the more burst-like kinetics of the other preparations. In neuroblastoma cells, doxorubicin-loaded PLGA-PEG nanoparticles (presumably due to their small size) and PLGA nanoparticles prepared by solvent displacement at pH 7 (presumably due to their high drug load and superior drug release kinetics) exerted the strongest anticancer effects. However, nanoparticle-encapsulated doxorubicin did not display increased efficacy in ABCB1-expressing cells relative to doxorubicin solution.Conclusion: Doxorubicin-loaded nanoparticles made by different methods from different materials displayed substantial discrepancies in their anticancer activity at the cellular level. Optimised preparation methods resulted in PLGA nanoparticles characterised by increased drug load, controlled drug release, and high anticancer efficacy. The design of drug-loaded nanoparticles with optimised anticancer activity at the cellular level is an important step in the development of improved nanoparticle preparations for anticancer therapy. Further research is required to understand under which circumstances nanoparticles can be used to overcome efflux-mediated resistance in cancer cells.
A new approach to silicon rhodamines by Suzuki–Miyaura coupling – scope and limitations
Authors: Kanagasundaram Thines , Timmermann Antje , Kramer Carsten S , Kopka Klaus 
Published: October 2019

Background: Silicon rhodamines are of particular interest because of their advantageous dye properties (fluorescence- and biostability, quantum efficiency, tolerance to photobleaching). Therefore, silicon rhodamines find frequent application in STED (stimulated emission depletion) microscopy, as sensor molecules for, e.g., ions and as fluorophores for the optical imaging of tumors. Different strategies were already employed for their synthesis. Because of just three known literature examples in which Suzuki–Miyaura cross couplings gave access to silicon rhodamines in poor to moderate yields, we wanted to improve these first valuable experimental results.Results: The preparation of the xanthene triflate was enhanced and several boron sources were screened to find the optimal coupling partner. After optimization of the palladium catalyst, different substituted boroxines were assessed to explore the scope of the Pd-catalyzed cross-coupling reaction.Conclusions: A number of silicon rhodamines were synthesized under the optimized conditions in up to 91% yield without the necessity of HPLC purification. Moreover, silicon rhodamines functionalized with free acid moieties are directly accessible in contrast to previously described methods.
New Neutron Star Equation of State with Quark–Hadron Crossover
Authors: Baym Gordon , Furusawa Shun , Hatsuda Tetsuo , Kojo Toru , Togashi Hajime 
Published: October 2019

Abstract
We present a much improved equation of state for neutron star matter, QHC19, with a smooth crossover from the hadronic regime at lower densities to the quark regime at higher densities. We now use the Togashi et al. equation of state, a generalization of the Akmal–Pandharipande–Ravenhall equation of state of uniform nuclear matter, in the entire hadronic regime; the Togashi equation of state consistently describes nonuniform as well as uniform matter, and matter at beta equilibrium without the need for an interpolation between pure neutron and symmetric nuclear matter. We describe the quark matter regime at higher densities with the Nambu–Jona–Lasinio model, now identifying tight constraints on the phenomenological universal vector repulsion between quarks and the pairing interaction between quarks arising from the requirements of thermodynamic stability and causal propagation of sound. The resultant neutron star properties agree very well with the inferences of the LIGO/Virgo collaboration, from GW170817, of the pressure versus baryon density, neutron star radii, and tidal deformabilities. The maximum neutron star mass allowed by QHC19 is 2.35 M
⊙, consistent with all neutron star mass determinations.
The Evolution of Baryonic Mass Function of Galaxies to z = 3
Authors: Pan Zhizheng , Peng Yingjie , Zheng Xianzhong , Wang Jing , Kong Xu 
Published: October 2019

Abstract
We combine the published stellar mass function (SMF) and gas scaling relations to explore the baryonic (stellar plus cold gas) mass function (BMF) of galaxies to redshift z = 3. We find evidence that at log(M
baryon/M
☉) > 11.3, the BMF has evolved little since z ∼ 2.2. With the evolution of BMF and SMF, we investigate the baryon net accretion rate (

) and stellar mass growth rate (

) for the galaxy population of log(M
star/M
☉) > 10. The ratio between these two quantities,

, decreases from

/

at z ∼ 2.5 to

/

at z ∼ 0.5, suggesting that massive galaxies are transforming from the “accretion-dominated” phase to the “depletion-dominated” phase from high-z to low-z. The transition of these two phases occurs at z ∼ 1.5, which is consistent with the onset redshift of the decline of cosmic star formation rate density (CSFD). This provides evidence to support the idea that the decline of CSFD since z ∼ 1.5 mainly results from the decline of baryon net accretion rate and star formation quenching in galaxies.
