Insertion of life sciences graduates in the labour market
No full textEnsuring student-centered training, oriented towards the labor market and carried out in partnership with sustainable
development actors ensures a favorable framework for increasing economic competitiveness, adapting production
processes to sustainable objectives and increasing the resistance of the economic environment to economic, social and
geopolitical vulnerability. The purpose of the research consisted in the analysis of the insertion of the graduates of the
University of Life Sciences in Iași (USV Iași) on the labor market. For this, a survey was carried out based on a
questionnaire administered to graduates after a variable period after their graduation. The data processing was carried out
using statistical tools agreed for the researched topic, including the TwoStep Cluster analysis. The results reveal an
insertion of graduates of 66.31%, percentage represented by 36.76% employees and 29.55% entrepreneurs, with small
differences between women (50.2%) and men (49.8%). Conversely, women preferred studies (19.1%) and employment
and men entrepreneurship (48.8%). Graduates of bachelor studies declared an employment of 22.6%, 6.5% continue their
studies. Among the employed respondents, 41.6% started a business or got hired in less than 3 months in the field of
completed studies (49.7%). Graduates of master's studies declared themselves employed in percentage of 81.3%, of which
40.2% are employees and 32.2% are entrepreneurs. The first form of employment or first entrepreneurial activity was
during studies for 28.8% and less than 3 months after finishing studies for 28.0%. Graduates of doctoral studies were
registered with the professional status of being employed for 38.7% of the respondents, of which 22.6% are employees,
9.7% are entrepreneurs and 9.7% are continuing their studies. The results recommend: the dynamic analysis of the
insertion of graduates on the labor market and their career path; analysis and correlation of educational plans and
developed skills in accordance with labor market demand; strengthening partnerships between USV Iași and public and
private economic organizations
The profile of fatty acids and the eggs quality from hens fed to the diet with flax seeds, rapeseed meal and vitamin E supplements
Get PDFThis experiment investigates
the effect of flaxseed meal, rapeseed meal
and vitamin E supplementation, when used
together, on the production parameters of
fatty acid composition and eggs quality
characteristics in Tetra SL laying hens (38
to 46 weeks of age). For this, 120 hens
were allocated one of three treatments, with
40 hens in each group. The hens were fed
either a control diet (C), a control diet
including 2.5 % flaxseed meal and 2.5%
rapeseed meal (E1) or 2.5% flaxseed meal and
2.5% rapeseed meal with 73 mg/ kg feed of
vitamin E as an antioxidant supplement (E2)
for 8 weeks. Hens consuming the E1 diet had
greater egg production and egg mass than
those from group C. The feed conversion
ratio in both the E1 and E2 groups was lower
(P < 0.05) than in the C diet group. E2 had
considerably higher egg weight, albumen pH,
yolk pH and Haugh unit than E1 and C (P0.05),
as a response to the vitamin E antioxidant
effect. The most α-linolenic fatty acid content
(1.07 g FAME) was found in eggs produced
by chickens fed the E2 diet, (1.07 g FAME),
followed by E1 (0.91 g FAME), with both
being significantly higher than C eggs
(0.23g FAME). Furthermore, all n-6 studied
fatty acids concentrations were significantly
lower (P < 0.05) in E1 and E2, while all n-3
fatty acids concentrations were significantly
greater (P > 0.05) in E1 and E2. When
comparing the n-6/n-3 ratio of fatty acids
from experimental treatments (6.44 and 6.74)
with C treatment (18.19), a significant
difference was observed (almost 65% lower)
Rezultate parțiale privind comportarea unor soiuri ornamentale de Ipomoea batatas cultivate în condițiile ecologice din Iași
Get PDFThe genus Ipomoea includes annual and perennial species, some of which are cultivated for ornamental purposes. Ipomoea batatas is a perennial species, grown as an annual in unprotected conditions. In this paper, the behavior of four cultivars of I. batatas ('Rusty Red', 'Midnight Lace', 'Light Green' and 'Purple Hearts'), cultivated in the experimental field of the discipline of Floriculture at the Iasi University of Life Sciences, Romania, was evaluated. Observations and determinations made after 35 days of establishment of cultures revealed differences between cultivars in terms of number of leaves/plant, shoots length and leaf size. The highest number of leaves and the longest shoots were recorded on the variety 'Rusty Red', while the variety 'Midnight Lace' stood out for the largest size of the leaves
Ovarian response to P4-PGF-FSH treatment in Suffolk sheep and P4-PGF-PMSG synchronization in cross-bred ewes,for IVD and ET protocol
Get PDFBackground
The success of an embryo transfer protocol in sheep depends on many factors, but the choice of drugs for the desired superovulation as well as the conception rate (CR) are most essential. Reproductive activity in sheep is characterized by a seasonality influenced by several factors such as photoperiod, latitude, temperature, nutrition and breed. Reproductive seasonality and nutritional condition are the main factors that influence embryo production in sheep. In sheep, some anatomical peculiarities limit the application of traditional reproductive biotechnologies used in cattle.
Objectives
The aim of this study was to conclude on the effectiveness of a wider on farm in vivo embryo transfer development programme in Suffolk sheep by streamlining hormone therapies and optimizing technique.
Methods
A total number of 60 sheep and three rams were included in this study, divided into two groups (receptors and donors). Donor Suffolk sheep were treated for superovulation using the P4-PGF-FSH multiple ovulation embryo transfer (MOET) protocol, while the cross-bred recipients’ group was synchronized with P4-PGF-PMSG.
Results
On the first day after superovulation, all ovaries had more than five dominant follicles, while corpora lutea were later observed in 83.3% sheep. The recovery rate was 83.3%, while 72.9% embryos were transferable. Embryos were transferred directly into recipients. Fertility after 30 days was 68.57%, lambing rate was 91.6% and CR was 62.85%. This study showed that veterinary drugs (P4, FSH, LH, PMSG, PGF) used for superovulation optimized by us were capable of producing by this improved technique the optimization of the reproduction indices at embryo-transfer (ET) and to be able to be used successfully.
Conclusions
The application of an MOET protocol has a positive effect in the production of in vivo embryo production (IVD) embryos in Suffolk sheep and can guarantee the success of embryo transfer activity to ewes with lower genetic merit. Our research aimed at representing a model for sheep farms for a rapid improvement of productive traits
The response of runner bean crop to irrigation and fertilization
Get PDFCurrently there is a growing interest both in obtaining large agricultural yields in order to provide food for
a growing population as well as in increasing the sustainability of production systems by improving the health
of the soil. The overall objective of this study was to evaluate the effect of organic versus chemical fertilization
versus irrigation on runner bean crop and soil health. A bi-factorial field experiment was organized in a split
plot design with three replicates during two years (2019 and 2020). The first factor, irrigation, had two
graduations: irrigated with 3000 m3/ha (Ir) and non-irrigated (Non-Ir). The second factor, fertilization, had
four graduations: biosolids (1200 kg/ha) (B), chemical (360 kg/ha) (Ch), microorganism (80 kg/ha) (M) and
unfertilized (Unfert). The results showed that, regarding the physiological state of the plants, both the
photosynthesis and the chlorophyll content were higher at Ir x M (5.31 µmol CO2/m2s2 and 45.23 SPAD units,
respectively). The yield of dried beans ranged between 1476-4811 kg/ha in 2019 and 1498-4727 kg/ha in 2020
and was highest for Ir x Ch. Soil health status estimated by determining the dehydrogenase activity in the soil,
has been improved for irrigated (Ir) and fertilized (B, M, Ch) variants
Research on the improvement of some technological parameters for Bromus inermis Leyss. seed crops
No full textThe fodder base represents the most significant means of increasing economic efficiency in the livestock sector. For
this, permanent and sown meadows are an important source of fodder. The establishment of temporary meadows on the
lands of steppe and forest-steppe areas, poorly productive, with erosion problems, the improvement of permanent
meadows by overseeding, the reforestation of slopes, slopes, irrigation canals, requires the production of large quantities
of perennial grass seeds, the most important species being Bromus inermis Leyss. The production of seeds for these
species is done in separate cultures, according to a specific technology. Through the research carried out within the
Research - Development Station for Meadows, Vaslui, was studied the influence of two factors, respectively, the
distance between the rows and fertilization with mineral fertilizers on the behavior of the species Bromus inermis
Leyss., in the first year of vegetation, being analyzed the ability of installation of the species and some
morphoproductive elements
Assessments of cryptocurrency accounting from an international perspective
No full textThe international accounting bodies concerned with the subject recognize the asset attributes of cryptocurrencies, but
have different views on their classification and dispute the valuation model for cryptocurrencies. Cryptocurrencies are
not cash or cash equivalents and do not have the characteristics of monetary assets as they do not have the
characteristics of a sovereign currency. Depending on the purpose of acquisition and holding, cryptocurrencies may be
classified as inventories or intangible assets, but the valuation model for cryptocurrencies and the gain or loss from
holding them again violates the current regulation of accounting standards for inventories and intangible assets.
Fluctuating market prices of cryptocurrencies make the financial and holding conditions of these assets less predictable
for individuals and businesses. As there are no accounting standards that specifically address crypto assets, existing
IFRS should be considered and a principle-based approach applied. The article highlights some of the approaches of
international financial accounting standards that are currently being debated and also shares views on how IFRS could
be applied to cryptocurrency accounting
The Effect of Sustainable Feeding Systems, Combining Total Mixed Rations and Pasture, on Milk Fatty Acid Composition and Antioxidant Capacity in Jersey Dairy Cows
No full textThis study was carried out to assess the effect of using pasture combined with total mixed ration (TMR) on milk production and composition, fatty acid (FA) profiles, fat-soluble antioxidant content, and total milk antioxidant capacity (TAC). In addition, the effect of milk pasteurization and storage at 2 °C for 4 days, lipophilic antioxidants and TAC were assessed. Two homogeneous groups of Jersey cows (n = 8) were constituted, which were randomly assigned to one of the two treatments: TMR (without access to pasture), or partial mixed diet (pTMR: grazing 8 h/day + TMR indoors). To establish FA profiles and lipophilic antioxidants’ changes in milk during the grazing period, in case of the pTMR group the experimental period was spilt in three grazing periods: P1 (May), P2 (June), and P3 (June/July). Milk yielded from cows having limited access on pasture (pTMR diet) showed an improved FA profile, with higher concentrations of FAs considered benefic for human health (vaccenic acid (VA), conjugated linoleic acid (CLA), omega-3 FA (n-3 FA)) (p < 0.01) and a lower concentration of FAs with hypercholesterolemiant potential (C12:0, C14:0, and C16:0) (p < 0.05), compared to that of the TMR diet. This change in FA profile was correlated with improved sanogenous lipid indices of milk fat (n-6/n-3 FA atherogenic index and thrombogenic index). Milk yielded during the P1 grazing period had higher concentrations of VA, CLA, and n-3 FA (p < 0.05) and lower concentrations of C14:0 and C16:0 (p < 0.01); it exhibited the best values for the main sanogenous fat lipid indices of fat. Moreover, pTMR milk showed a higher α-tocopherol, retinol, and β-carotene content (p < 0.05), positively correlated with TAC values in milk (P1 ˃ P2 ˃ P3). By comparison, cows fed using the TMR diet yielded a higher quantity of milk (p < 0.05), but a lower fat and protein content (p < 0.01), and also a higher saturated FAs and n-6 FA content (p < 0.05) together with a lower concentration of lipophilic antioxidants in milk. Thermal treatment showed no effect on α-tocopherol and retinol content in milk, but their concentrations decreased during the storage, at the same time a TAC decrease. The results of this study prove the positive effect of using pasture combined with TMR on FA profiles, milk antioxidant content, and antioxidant capacity, with beneficial effects on nutrition and health in humans
Economics of Rebreeding Nonpregnant Dairy Cows Diagnosed by Transrectal Ultrasonography on day 25 after Artificial Insemination
No full textPregnancy rates of Holstein cows showed a substantial decline in the past years, which caused intensive TAI programs for nonpregnant cows to shorten the period between unsuccessful insemination and the next attempt on the same cow. Although many studies examined the improvement in pregnancy rates following TAI, only a few examined the economic impact of such programs. In this study, we look at the feasibility of reproductive programs that included early pregnancy diagnosis performed by transrectal ultrasonography 25 days after artificial insemination (AI) and TAI of nonpregnant cows. This resulted in the following two TAI programs: a modified OvSynch program with a second PGF2α treatment at 24 h interval (GPPG, n = 100) and a modified OvSynch program with an intravaginal progesterone-release device inserted between days 0–7 (PRID + GPPG, n = 100). Cows included in the TAI programs recorded an improvement in the cumulative pregnancy rate (67% vs. 53%; 69% vs. 53%) compared to those in which this strategy was not applied (p < 0.05). An economic analysis was performed using a decision-support tool to estimate the net present value (NPV; USD/cow/year). The analysis revealed a difference in NPV of 89.6 USD/cow/year between the programs (rebreeding the nonpregnant cows following the TAI program vs. AI at detected estrus). In summary, rebreeding the nonpregnant cows after early negative pregnancy diagnosis (25 days after AI) using this strategy can improve the cumulative pregnancy rate and profitability of dairy farms
Periodontal Tissue Reaction Consecutive Implantation of Endodontic Materials and Subsequent Integration of Complex Oral Rehabilitation Treatments
No full textOral rehabilitation is a main branch of dentistry focused on diagnosing the patient’s problem and creating a treatment plan to restore aesthetics, recondition morphologically all components, and recover the functionality of the oral cavity. Biological compatibility of the materials used has a major importance, due to the direct contact with essential tissues, such as the soft and hard tissue of the periodontium and the potential influence on the outcome of the treatment. The present material aims to assess the inflammatory response after subcutaneous implantation of three materials frequently used in endodontics (Mineral Trioxide Aggregate—MTA, DiaRoot BioAggregate, and Sealapex). The evaluation of the reparative tissue reaction after 7, 30, and 60 days, respectively, subsequent to in vivo implantation, was carried out through electron microscopy imaging. Moreover, evaluation of the dynamics of the osteogenesis process was an indicator for the maintenance of internal homeostasis in the context of complex intraoral rehabilitation treatments that include fixed prosthodontics correlated with the particular periodontal-aesthetic aspects and completed by cranio-mandibular repositioning. Our study showed increased absolute values of alkaline phosphatase in all material-implanted cases (more pronounced in MTA and Bio Aggregate), highlighting that this enzyme could be an effective indicator of bone formation, which takes place after the material implantation, with the most significant elevated values at 30 days postoperatively
