Revival of Philozoon Geddes for host-specialized dinoflagellates, âzooxanthellaeâ, in animals from coastal temperate zones of northern and southern hemispheres
The dinoflagellate family Symbiodiniaceae comprises numerous genera and species with large differences in diversity, ecology and
geographic distribution. An evolutionarily divergent lineage common in temperate symbiotic cnidarians and designated in the
literature by several informal names including âtemperateâAâ, AI, Phylotype AÂŽ (A-prime) and âMediterranean Aâ, is here assigned to
the genus Philozoon. This genus was proposed by Geddes (1882) in one of the earliest papers that recognized âyellow cellsâ as distinct
biological entities separate from their animal and protist hosts. Using phylogenetic data from nuclear (rDNA), chloroplast (cp23S)
and mitochondrial genes (cob and cox1), as well as morphology (cell size), ecological traits (host affinity) and geographic
distributions, we emend the genus Philozoon Geddes and two of its species, P. medusarum and P. actiniarum, and describe six
new species. Each symbiont species exhibits high host fidelity for particular species of sea anemone, soft coral, stony coral and
a rhizostome jellyfish. Philozoon is most closely related to Symbiodinium (formerly Clade A), but, unlike its tropical counterpart,
occurs in hosts in shallow temperate marine habitats in northern and southern hemispheres including the Mediterranean Sea,
north-eastern Atlantic Ocean, eastern Australia, New Zealand and Chile. The existence of a species-diverse lineage adapted to
cnidarian hosts living in high latitude habitats with inherently wide fluctuations in temperature calls further attention to the
ecological and biogeographic reach of the Symbiodiniaceae

Al VI-lea Congres NaÈional de ObstetricÄ Èi Ginecologie cu participare internaÈionalÄ, 13-15 septembrie 2018, ChiÈinÄu, Republica MoldovaIntroduction: The installation of macro-circulation centralization in MODS triggering in critical obstetric states caused by intravascular coagulation, HELLP, shock, SIRS, septicemia, CARS, embolism of the pulmonary artery, cerebral and other, â microcirculation will also be seriously damaged, as the reduction in blood flow perfusion affects the venous return to eliminate the waste of cellular metabolism, where a marker of tissue hypoxia is the increase in carbon dioxide.
Objective: The mitochondrial microcirculatory recruitment with multiple organ support therapy in extracorporeal life support.
Material and methods: This is a retrospective study over 35 years, in a lot of critical situations in obstetrics.
Results: This disorder generates microcirculatory - mitochondrial distress syndrome, mitochondrial energy collapse, which can be recovered by microcirculation â mitochondrial recruitment to optimize systemic perfusion pressure (SPP), in turn, dependent on mean blood pressure and capillary resistance. Microcirculation - mitochondrial recruitment
decentralizes macrocirculation benefits microcirculation in the capillary-cell metabolic area.
In cases of manifestation respiratory-pulmonary CO2 â (ARDS), confirmed â PaO2/FiO2 â300 to Acute Respiratory Distress Syndrome (Berlin definition, 2012), thus also aggravates the microcirculatory-mitochondrial distress syndrome, mitochondrial collapse and the recruitment of the microcirculatory-mitochondrial is supplemented with
multi-organ support therapy (MOST). 1. Alveolar recruitment through respiratory support in specific ventilation modes, predominantly APRV, with permissive hypercapnia at a normal pH. 2) MOST - extracorporeal with technical support. Extracorporeal Life Support Organization â ELSO. 3) Modeling of extra-vascular pulmonary fluid; 4) Th4 - Th5 thoracic
epidural block.
Conclusion: The absence of decreasing of the pCO2 tissue hypoxia marker at the A-V difference after microcirculatory - mitochondrial recruitment, rejects the necrosis /apoptosis, cellular hypo-(an)ergic and proves the mitochondrial eu-energetic metabolic remodeling with the elimination of the hypo (an) ergic mitochondria performed by clearance lysosomal (mitophagy), thus demonstrating eu-ergic mitochondria with the normalization of mitochondrial uniporter-Ca ++ and mitochondrial permeability pore transition, which productively inactivate the toxic forms of oxygen and nitrogen.Rezumat.

Parallel algebraic multilevel Schwarz preconditioners for a class of elliptic PDE systems
Algebraic multilevel preconditioners for algebraic problems arising from the discretization of a class of systems of coupled elliptic partial differential equations (PDEs) are presented. These preconditioners are based on modifications of Schwarz methods and of the smoothed aggregation technique, where the coarsening strategy and the restriction and prolongation operators are defined using a point-based approach with a primary matrix corresponding to a single PDE. The preconditioners are implemented in a parallel computing framework and are tested on two representative PDE systems. The results of the numerical experiments show the effectiveness and the scalability of the proposed methods. A convergence theory for the twolevel case is presented
Impact of internet of things (IoT) in disaster management: a task-technology fit perspective
YesDisaster management aims to mitigate the potential damage from the disasters, ensure immediate and suitable assistance to the victims, and attain effective and rapid recovery. These objectives require a planned and effective rescue operation post such disasters. Different types of information about the impact of the disaster are, hence, required for planning an effective and immediate relief operation. The IoT technology available today is quite mature and has the potential to be very useful in disaster situations. This paper analyzes the requirements for planning rescue operation for such natural disasters and proposes an IoT based solution to cater the identified requirements. The proposed solution is further validated using the task-technology fit (TTF) approach for analyzing the significance of the adoption of IoT technology for disaster management. Results from the exploratory study established the core dimensions of the task requirements and the TTF constructs. Results from the confirmatory factor analysis using PLS path modelling, further, suggest that both task requirements and IoT technology have significant impact on the IoT TTF in the disaster management scenario. This paper makes significant contributions in the development of appropriate constructs for modeling TTF for IoT Technology in the context of disaster management
The association in a two-way contingency table through log odds ratio analysis: the case of Sarno river pollution
THE EVALUATION OF PASSENGER SATISFACTION IN THE LOCAL PUBLIC TRANSPORT: A STRATEGY FOR DATA ANALYSIS
The diffusion of ISO 9001:2000 certification and adoption of mobility charter led the companies of Local Public Transport (LPT) for carrying out surveys of Passenger Satisfaction (PS). However, often, the data analysis is limited to the application of descriptive and explorative statistical techniques. In this way, the collected data are used in inefficient way and information that are transferred to the company management are not sufficient to make decisions.
A good analysis strategy requires the use of a combination of parametric and nonparametric techniques. In this paper we propose the combined application of Rasch Analysis and Simple Components analysis based on the RV coefficient (SCA-RV)

Redescription of Pelagia benovici into a new jellyfish genus, Mawia, gen. nov., and its phylogenetic position within Pelagiidae (Cnidariaâ:âScyphozoaâ:âSemaeostomeae)
This study provides new and additional data on morphology and a phylogenetic analysis of the recently described species Pelagia benovici Piraino, Aglieri, Scorrano & Boero, 2014 from the Northern Adriatic (Mediterranean Sea). Comprehensive morphological analyses of diagnostic characters, of which the most significant are marginal tentacles anatomy, basal pillars, gonad pattern, subgenital ostia and exumbrellar sensory pits, revealed significant differences from the currently known genera Sanderia, Chrysaora and Pelagia in the family Pelagiidae. A phylogenetic analysis of mitochondrial genes (COI, 16S rRNA, 12S rRNA) and nuclear ribosomal genes (28S rRNA, ITS1/ITS2 regions), together with cladistic analysis of morphological characters, positioned Pelagia benovici as a sister taxon with Sanderia malayensis, and both share a common ancestor with Chrysaora hysoscella. Pelagia benovici does not share a direct common ancestor with the genus Pelagia, and thus we propose it should not belong to this genus. Therefore, a new genus Mawia, gen. nov. (Semaeostomeaeâ:âPelagiidae) is described, and Pelagia benovici is renamed as Mawia benovici, comb, nov
