New and rare plants from the flora of Moldavia (Romania)
In this scientific paper, some
vascular plants (Aster lanceolatus Willd.,
Aster novi-belgii L., Fraxinus
pennsylvanica Marshall, Picris echioides L.
and Festuca tenuifolia Sibth.) were shown
as new species from the spontaneous flora
of Moldavia. We have also analysed new
data on some rare vascular species found in
the flora of this region (Coreopsis tinctoria
Nutt., Ulmus pumila L., Rudbeckia triloba
L., Rudbeckia hirta L., Lupinus polyphyllus
Lindl., Oenothera glazioviana Micheli and
Rhus typhina L.). One of these species is
native (Festuca tenuifolia Sibth.), while the
others are alien plants. Among the alien
species, Picris echioides L. is xenophyte
(accidentally introduced) and the others are
hemerophytes (intentionally introduced for
different uses and, subsequently, escaped in
the wild). Given the number of localities in
which these species were found, we may
consider that the following alien plants had
an invasive tendency in Moldavia: Fraxinus
pennsylvanica Marshall, Ulmus pumila L.,
Oenothera glazioviana Micheli, Rhus
typhina L. and Lupinus polyphyllus Lindl.
The other species may be considered
naturalized (most of them), being able to
form populations without human help.
Except Festuca tenuifolia Sibth., which
grew in natural grasslands, all the other
identified species were integrated in
anthropic habitats. Aster lanceolatus
Willd., Rudbeckia triloba L., Rudbeckia hirta
L., Lupinus polyphyllus Lindl. and Rhus
typhina L. also penetrated into semi-natural
habitats: forest edges, river banks and river
meadows. As concerns Festuca tenuifolia
Sibth., a very rare species in the flora of
Romania, included in the Romanian Red
List of Vascular Plants, its presence in
Moldavia, to the South-Eastern limit of its
natural area, is very interesting and
encouraging
GENERAL ASPECTS REGARDING THE GROWTH FRESHWATER FISH IN CUBES, AN ALTERNATIVE FOR AQUACULTURE IN ROMANIA
Due to the increased consumption of fish, as an alternative to achieving healthy population nutrition, the development of European aquaculture also shows an increasing trend. At present, freshwater culture is about 42% of total European fish production. Valuable species, from an economic point of view, can be reared in intensive systems in cages on running waters or ponds, combined with less valuable species. There are also new species that are gradually becoming increasingly important for the fish industry in Europe. Freshwater aquaculture in Romania is based on rainbow trout and carp which are still predominant species, but there is significant demand for valuable fish species [11,12,16]. Â

Nicolae Testemitanu SUMPh, Medical Territorial Association Botanica, Chisinau, Medical Territorial Association Buiucani, ChisinauTuberculosis detection represents the major challenge in actual health care system of the Republic of Moldova. The aim of the study was the assessment of the features and risk factors of 101 patients with pulmonary tuberculosis detected in the frame of the primary health care of Chisinau city and diagnosis confirmed by molecular genetic method GeneXpert MTB/Rif. The research results established that more frequently were detected patients with lack of health insurance and poor social economical state. The risk factors such as chronic alcoholism, drug consumption, and history of detention, migration and comorbid state were identified in a low proportion. Despite the fact that high risk groups such as persons with tuberculosis contact and HIV infected individuals must be detected by active screening, they were detected predominantly by passive way. Despite the fact, that severe and extensive clinical radiologic forms predominated in patients detected by addressing, the treatment success rate was without differences compared with patients detected by active screening.
.Depistarea tuberculozei reprezintă o provocare majoră pentru sistemul actual de sănătate al Republici Moldova. Scopul cercetării a fost evaluarea particularităţilor şi a factorilor de risc a 101 pacienţi cu tuberculoză pulmonară, depistaţi în cadrul asistenţei medicale primare din municipiul Chişinău şi cu diagnostic confirmat prin metoda molecular-genetică GeneXpert MTB/RIF. Rezultatele studiului au confirmat că mai des au fost depistaţi pacienţi neasiguraţi, cu o stare socioeconomică precară. Factorii de risc precum alcoolismul cronic, consumul de droguri, istoricul de detenţie, migraţia şi comorbidităţile au fost identificaţi într-un număr redus. În pofida faptului că grupele cu risc înalt, precum persoanele cu contact tuberculos şi cele infectate HIV, trebuie să fie depistate prin screening activ, acestea au fost depistate mai frecvent pasiv. Deşi formele clinico-radiologice severe şi extinse au predominat la pacienţii depistaţi prin adresare, rata succesului terapeutic nu s-a diferenţiat de cea a pacienţilor depistaţi prin screening activ.Выявление туберкулеза является серьезной проблемой для нынешней системы здравоохранения Республики Молдова. Целью исследования было определить особенности и факторы риска 101 пациентов с туберкулезом легких, выявленных в рамках первичной медико-санитарной помощи города Кишинэу и с подтвержденным диагнозом молекулярнo-генетическим методом GeneXpert MTB/Rif. Было установлено, что чаще всего были выявлены пациенты без медицинской страховки и со сниженным социально-экономическим статусом. Факторы риска, такие как хронический алкоголизм, употребление наркотиков, тюремное заключение, миграция, сопутствующие заболевания, были установлены у несколько случаев. Вопреки рекомендации активного выявления групп повышенного риска, включавшие людей с туберкулезным контактом и ВИЧ-инфицированные лица, они были обнаружены преимущественно пассивным путем. Несмотря на то, что тяжелые и обширные клинико-рентгенологические формы преобладали у пациентов, выявленных при обращении, доля успешно вылеченных было одинаково по сравнению с долей пациентов, выявленных активным путе
CONSIDERATIONS ON ENERGETIC CROPS POTENTIAL
In order to breathe fresh and clean air, nature and terrestrial atmosphere should be preserved and protected. Carbon emissions represent one of the main enemies of air quality. Recently, carbon emissions have surpassed all the predictions because the excessive industrialization, becoming the determining factor for global warming. A viable alternative to carbon emissions reduction is the utilization of energy sources that can diminish the noxious substances emissions up to zero. This can be done by using the power of wind, sun, water, energy plants, etc. Among the energetic potential plants, the biomass is obtained- a form of renewable energy which final product is biofuel
BENEFITS OF USING ADDITIVES FOR IMPROVING THE QUALITY OF PELLETIZED ANIMAL FEED
The animal husbandry sector is one of the largest in the world. In order to maintain the same effectives of animals throughout the year, the necessary feed needs to be ensured. Due to the fact that the animal feed is seasonal, is important to find ways to preserve the fodder to be used all year. One of the best ways to preserve fodder is to pelletize it. The paper presents a series of researches on the benefits of using additives in animal feed pellets, improving a series of quality attributes, such as overall aspect, durability, single pellet and bulk density
IMPROVING THE ENERGY CONSUMPTION OF AN INTENSIVE RECIRCULATING ACQUACULTURE SYSTEM USING A WATER-WATER TYPE HEAT PUMP
Aquaculture efficiency practiced in recirculating systems depends on a variety of factors, among which the most important is the energy consumed by the whole system. In order to assure a high degree of energy conservation, in a recirculating aquaculture system has to be maximized the recirculating water degree and has to be imposed the use of renewable energy sources for heating, respective for cooling the water within system as well as of hall. Maintenance of an appropriate climate in a recirculating aquaculture system involves high energy consumption, determined by high water quantities which have to be heat or cool, as well as determined by maintaining water temperature and of breeding space. An optimal solution for replacing conventional systems of heating/cooling and optimizing of energy consumption is the use of the heat pumps. In the present paper are presented experimental results performed with a heat pump of water-water type at different water replacing rates and two different water flows for demonstrating efficiency of a heat pump for improving energy consumption of a RAS
