Bilateral uterine prolapse in queen: case study
No full textAn 10-month-old primiparus queen was sent to the Department of Obstetrics and Gynecology within the Faculty of
Veterinary Medicine from Iași, with a prominence of a mass through the vulva immediately after calving. Following the
clinical examination, the diagnosis of bilateral uterine prolapse was established. Uterine prolapse in cats is rare and is a
relatively uncommon complication of parturition. This pathology is an obstetrical emergency and requires immediate
intervention. The treatment of uterine prolapse consisted in restoring the uterus to its normal position and preventing or
eliminating uterine infection. In the present case the manual reduction of the prolabated portion was not possible and a
two-step ovariohysterectomy was performed: ovariectomy and amputation of the uterine body.
After ovariohysterectomy cat fully recovered
Lumbosacral transitional vertebra (LTV) in cat: a case report
Get PDFThe observations of the study were focused on the lumbosacral region of the spine in cats in order to identify some
peculiarities or abnormalities in the anatomical conformation regarding the number of the vertebra or other morphological
aspects. For this purpose were analyzed the radiographs of the lumbosacral region of 63 feline patients of a veterinary
clinic, both males and females, 1-9 years aged, which showed various symptoms, especially locomotor. The x-ray exam
revealed sundries pathologies of the spine, but among them in a cat of European breed it was remarked an abnormal
anatomical conformation of the lumbosacral spine consisting in the sacralization of the last lumbar vertebra. It was noticed
that the last lumbar vertebra is fused with the first sacral one in a large degree, both vertebral bodies and the transverse
processes being merged, the sacrum bone containing four sacral vertebra instead of three, as normally does. It was counted
also three ventral sacral foramina, instead of two. The particular characteristics noticed conducted to the observation that
the last lumbar vertebra represents in fact a lumbosacral transitional vertebra (LTV) which in cats occurs at a low rate
Models of optimization and simulation of agricultural crop plans in agricultural holdings in Romania
No full textThe purpose of this paper is to promote the setting up of farms whose size will allow the practice of a viable, sustainable
agriculture, capable to apply the newest technologies and lead to profit and efficiency, to the economical and
organizational consolidation. The essential criterion in optimizing the crop structure is the economic efficiency,
respectively the realized profit. Economic efficiency is constantly changing due to changes in raw material prices and
commodity production. Hence the need to optimize the structure of crops in each cycle of agricultural production. The
main indicators used in optimizing the structure of crops are: yield per hectare, production costs per unit area, profit per
hectare, unit cost and rate of return. As a consequence, the resizing of the agricultural holdings, the partnership between
the producers, the integration of the agricultural production, the rural development, the consumers’ constant request for
agricultural and food products, the decrease of the deficit of the commercial balance for the agricultural products, the
increase of the population’s life standard, the safety of the food, all these are goals that have to be under the continuous
attention of the authorities at central and local level. The elaboration of mathematical models was oriented on the design
of several structural alternatives and the elaboration of a large number of variants, because analysing the problem of
establishing an optimal structure through the prism of several variants creates the possibility of highlighting the
development and manifestation of different phenomena, some conclusions, not by subjective assessments or by
antithesis, but on the basis of several concrete structures that each variant covers
Nitrogen status and canopy density detection of vegetation using multispectral data
No full textThe use of ground-based
multispectral data for the evaluation of
plant water stress and nitrogen status in
Old Oyo national Park, Nigeria was
conducted and classification was
performed. The active area of nitrogen
concentration in hectares was between
0.0 and 0.4. This active area was expressed
in hectares (ha) and percentages (%)
respectively. From the assessment, 53.52 ha
(69%) and 24.29 ha (31%) were recorded
at 0.2-0.4 and 0.0-0.2, respectively. Heat
stress takes place when the regular
temperature is above 30ºC, which could
slow down plant growth and lead to the
threat of deficiency. The heat stress
reached a maximum of 40ºC in this
analysis between February and May. The
research concluded that the sustainability
of crops and trees requires a certain
quantity of 69 percent nitrogen and a
certain level of wetness for their growth
which is between 400 mm and 800 mm
rainfall
Aspecte privind influenţa unor structuri compozite polimerice susceptibile biodegradării asupra procesului de dezvoltare a plantelor
Get PDFThis paper presents some results referring to the influence of some composite structures based on lignin (L), wood powder (PL), and low density polyethylene (LDPE) (Arpechim Pitesti), incorporated into the soil, on the process of growth and development plant. The experiment took place in laboratory conditions at 23-25oC. As biological material one used tomato seeds (Lypercosium esculentum, variety San Marzano) offered by USV Iasi. The evolution of plants was monitored for 35 day and during this period one realized some analyses as: the capacity of germination, the quantity of green and dry biomass, which offer indices upon the possible stimulative effect of the products used. For biodegraded composite materials, the surface aspects were analyzed visually and with the help of SEM microscopy. According to this research one has established that composite products used are susceptible to biodegradation and positively influence the growth and development of plants, except for polyethylene, so they can contribute to soil bioremediation
Imination of chitosan nanofibers in a heterogeneous system. Synthesis optimization and impact on fiber morphology
No full textThe paper aimed to prepare imino-chitosan fibers by the imination reaction in a heterogenous system, targeting the
improvement of anti-pathogenic activity. To this end, porous neat chitosan fibers were prepared by electrospinning of
the polyethylene glycol/chitosan blend, followed by polyethylene glycol removal. Imination of the neat chitosan fibers
was carried out in three liquid phase systems using solvents of different polarity and, consequently, different ability to
swell the solid phase chitosan fibers. The successful imination was qualitatively and quantitatively assessed by FTIR
and 1H-NMR spectroscopy, and the impact of the liquid phase on the fibers’ morphology was evaluated by SEM, POM
and AFM microscopy. Further, the antimicrobial activity of the imino-chitosan fibers was investigated on relevant
bacterial and fungal strains. It was concluded that the prior swelling in water of the fibers improved the imination
degree, while the use of a less polar solvent, such as toluene, favored the preservation of the fibrous morphology. The
imination with an antimicrobial aldehyde endowed the chitosan fibers with the ability to create a physical barrier
against pathogens
Modalități de reabilitare a fațadelor prin folosirea jardinierelor
Get PDFIn the context of urbanization accentuated in recent decades, there has been an orientation towards paradigms, which will shape human settlements in a sustainable way able to meet the needs of adaptability to climate change, ensuring primarily environmental quality and conservation of species and habitats. In cities, paved or concrete constructions and surfaces create a specific urban climate, with higher temperatures and a restriction of air circulation, which leads to the production of the so-called "heat island" effect. In contrast, vegetation, through the effect of shade and increasing air humidity contributes to creating a more comfortable environment. Hence the use of the phrase "park - cool island". Lately, a compositional concept of capitalization of vegetation is making its presence felt more and more, emphasizing both the aesthetic role and the role of purification and regeneration of the polluted environment. The solution approached by this work are the arrangements on the vertical given the fact that in the urban environment the vegetation has a role not only aesthetic but also sanogenic

No full textThe researches regarding the flight dynamics of the pest Cydia Pomonella L. were carried out on the territory of Iași county in Miroslava locality, in an intensive apple plantation and the varieties studied being Florina, Idared and Jonagold. The appearance of the pest Cydia Pomonella L. was followed with the help of pheromone traps of atraPom type, produced by the Institute of Chemical Research, “Raluca Ripan” from Cluj-Napoca. During the year, the pest had 2 complete generations, the first occurrence being reported on May 7. The maximum flight curve of the first generations was reached on May 24, with a flight staggered throughout the vegetation period of the culture, the flight of butterflies being recorded during a number of 123 calendar days. Pest biology has been heavily influenced by climatic conditions
Valorization of vine tendrils resulted from pruning as densified solid biomass fuel (briquettes)
Get PDFConcerns over the past few decades have focused, more than ever, on finding and implementing
efficient, handy, and renewable sources to reduce pollution. Biomass, in general, and
biomass from annual vine cuttings, are renewable sources that can be used by a large amount of
the population. Biomass densification in the form of briquettes is an efficient method of obtaining a
biofuel with the same characteristics as wood. The production of densified material as a briquette
consists of sampling, drying naturally, chopping, grinding and briquetting the vine cuttings. The
obtained results showed that the size of the briquettes met the requirements imposed by the standard,
with a length between 185 mm and 400 mm and a diameter of 58 0.75 mm, the humidity of the
briquettes varying between 5.42%, at Sauvignon Blanc and 7.98% for Pinot Noir, while the durability
of the briquettes registered minimum values of 98.17% for Muscat Ottonel and a maximum of 99.14%
for Feteasca Neagra, and a unit density with values between 1227 kg/m3 for Feteasca Alba and
1389 kg/m3 for Pinot Noir. The conclusions of these experiments are promising, showing that the
densification of biomass from vines cuttings qualifies within the standard requirements for obtaining
a valuable biofuel
