Determination of phosphate in water by flow coulometry
Authors: Manová A. , Beinrohr E. 
Published: November 2020

Abstract
In this work, the possibility of flow coulometry application as coulometric titration was studied. The method was used to analyze phosphates in wastewater samples. The principle of the determination consisted in the formation of molybdophosphate and its subsequent one-electron electrolytic reduction. The present method is applicable under optimal conditions in the concentration range of 1.5 × 10−6 to 5.5 × 10−5 mol/dm3. Detection limit of the method is 3.42 × 10−7 mol/dm3. Mineralization step has been proved a problem in total phosphate content determination. If mineralization was not carried out, only inorganic soluble phosphates were determined. It is a new method characterized by its simplicity of instrumentation and handling, which is a prerequisite for its further use in the field of trace analysis.

Abstract

Objective: To establish the association between ultrasound (US) burden with articular MSU crystals and renal morphology, blood supply, function and arteriosclerotic carotid arteries alterations in gout patients, individuals with asymptomatic hyperuricemia and no sign of inflammatory arthritis and psoriatic arthritis subjects with asymptomatic hyperuricemia.

Methods: 121 consecutive patients were included: 85 patients with gout, 27 subjects with asymptomatic hyperuricemia and 9 psoriatic arthritis patients. Subjects underwent US of both kidneys, common carotid arteries and bilateral US of the joints of the hands, elbows, knees, ankles and feet. For intrarenal blood flow we judged by measuring the renal resistive index (RRI). By US of the carotid arteries were determined intima-media thickness (IMT), common carotid artery resistive index (CCARI) and the presence of atherosclerotic plaques was registered.

Results: Individuals with articular US MSU deposits compared to those without had higher RRI (p = 0.035) and smaller kidney size (p = 0.014), but renal parenchymal thickness (p = 0.893), echogenicity (p = 0.291), IMT (p = 0.165), CCARI (p = 0.097), the frequency of nephrolithiasis (p = 0.438) and atherosclerotic plaques (p = 0.830) were similar. Subjects with US evidence of MSU crystals in two or more joint regions had the highest RRI (p = 0.002) and CCARI (p = 0.019). Compared to gout patients the risk of MSU crystal accumulation in the joints of asymptomatic hyperuricemia group was lower by 82.7%, OR = 0.173 (95% CI; 0.060 – 0.498, p = 0.001), while in psoriatic arthritis patients the risk was lower by 82%, OR = 0.180 (95% CI; 0.038-0.861, p = 0.032).

Conclusions: This study points out that subjects with larger extent of articular MSU burden have greater vascular stiffness. The accumulation of MSU crystals in the joints may be associated with the accumulation of crystals mainly in the renal interstitium.

Authors: Roşescu Ruxandra , Cînpeanu Oana Cristina , Teodorescu Claudiu , Tarcea Monica 
Published: November 2020

Abstract
The prevalence of diabetes has doubled in the last 4 decades in Romania. Our goal was to identify the risk profile in a group of Argeş county patients based on the Finnish Diabetes Risk Score (FINDRISC) score and main variables analysed. Our study was based on a pilot study on a group of 103 patients. The Finnish Diabetes Risk Score was used to calculate the risk of developing diabetes for our patients. In our group, the FINDRISC score was not statistically significantly correlated with body mass index, but was statistically significantly correlated with hypertriglyceridemia, low HDL-Cholesterol levels, hyperuricemia, hyperglycemia, and hypertension. The older you get, the higher your risk of developing diabetes. The present study demonstrates the importance of lifestyle in terms of the risk of developing diabetes, supporting the need to implement more effective health education measures on a balanced lifestyle and establishing interdisciplinary mechanisms of collaboration between physician, nutritionist and psychologist to promote health.

Authors: Boţan Adriana , Chiş Monica , Copotoiu Sanda-Maria 
Published: November 2020

Abstract
The first and most important step in pain management is to correctly assess it. Short-form McGill Pain Questionnaire-2(SF-MPQ-2) and Multidimensional Pain Evaluation Scale (MPES) are valid and reliable tools used in clinical practice and research. Our aim was to evaluate the efficacy of pharmacological and non-pharmacological treatments applied for pain relief. 27 patients were included in the study, of which 12 were outpatients and 15 were inpatients. Statistical and clinical significant differences were obtained only for the inpatient group on the MPES (p=0.00, difference between means=3.07) and for 3 out of 4 domains of the SF-MPQ-2 (p=0.01, 0.01 and 0.00 and the difference between means=2.60, 2.00 and 2.20 for continuous pain, neuropathic pain and affective descriptors, respectively). Outcomes of pain management are better for inpatients due to a combination of analgesic drugs with physical medicine and rehabilitation procedures and a strict monitoring during their hospitalization.
Reconstruction of a Lower Lip Defect with Bilateral Nasolabial Musculocutaneous Flap. Case Report
Authors: Helgiu Alina 
Published: November 2020

Abstract
Squamous cell carcinoma is the most common form of malignant tumour in the lower lip and its radical excision sometimes leads to complex defects. The treatment of squamous cell carcinoma of the lower lip is mainly surgical and consists of complete excision of the tumour, followed by immediate reconstruction. Although the nasolabial flap is a common flap used in the reconstruction of facial defects, it is an underestimated option in the reconstruction of the lower lip. We describe the reconstruction of a large defect of the lower lip that includes the bilateral commissures and ¼ of the upper lip, left side, in a 76-year-old male patient. Bilateral musculocutaneous nasolabial flap was used, with good functional results and an acceptable cosmetic result. We believe that the nasolabial flap is a good alternative for large lip defects both for patients with an affected general condition, but also as an alternative to existing flaps.

Authors: Laslo Alexandru 
Published: November 2020

Abstract
Uterine leiomyoma is the most common benign tumour encountered in female genital pathology. It originates from the level of the smooth muscle tissue, and from the morphological point of view, the tumour is well delimited, being surrounded by a pseudocapsule. We report a case of a 46-year old woman who, following a CT scan performed for epigastric abdominal pain and nausea, showed a dense bulky tumour formation, with multiple hyperdense inclusions inside and well-defined areas of necrosis, with maximum axial diameters of 133/168/249 mm (LL / AP / CC), having as a starting point most likely the uterine upper pole. A total hysterectomy is performed, with bilateral anexectomy, and the histopathological examination describes a giant subserosal leiomyofibroma of the uterus with signs of hyaline degeneration, left hydrosalpinx with strong stasis of the left tube, follicular hemorrhagic cysts of the left ovary.

The purpose of this study is to generate data, which can be used to support decisions on improving the health of dental technicians, whose basic activity is carried out in a sitting position at the work table, in order to improve the quality of life. Implementation of ergonomic measures, in the area where professional activities directly affect the physical and mental health of the employee, is of great importance.
The dynamics of agri-food trade between the EU28 and East African Community (EAC)
Authors: Zdráhal Ivo , Verter Nahanga , Bečvářová Věra 
Published: November 2020

Abstract
The increasing number of regional blocs and interdependence of nations have become important aspects of global economic integration. The European Union (EU28) as one of the most advanced regional bodies has had preferential trade agreements with other regional bodies, such as the East African Community (EAC). Historically, the EU28 has been the EAC’s leading trading partner. Against this background, this paper analyses the dynamics of bilateral trade in agri-food between the two regional blocs for the period 2000–2018, using the battery of empirical tools.
The findings indicate that even though the EU has finalised trade agreements with the EAC, it holds on the region regarding trade has diminished. The EAC bloc has diversified its trading partners (to other African countries, India and China) beyond the EU28 markets. The results further reveal that the EU28 has comparative advantages in 32 out of 46 agri-food products in trading with EAC. The export concentration ratios show the EU28 slightly concentrated more in exporting products to the EAC than EAC to the Union. The BCG findings reveal (un)competitive and/or promising (dropping) products in export structures of both regions. By and large, the results indicate certain shifts in the comparative advantage, specialisation/diversification of exports and competitiveness of specific products on the bilateral level between EU28 and EAC. Policymakers, especially from EAC should continue to create enabling environments to stimulate food processing, trade and monitor changes in trade patterns or shocks within the framework of the Partnership Agreement.
Life cycle assessment of fermented milk: yogurt production
Authors: Ghinea Cristina , Leahu Ana 
Published: November 2020

Abstract
Yogurt is a fermented milk product, resulted through milk acidification by lactic acid bacteria, highly appreciated worldwide. In this study, life cycle assessment (LCA) methodology was applied for modelling of environmental impacts associated with yogurt production. The system boundaries include the following activities: milk processing, transport, solid waste and wastewater treatments. Functional unit set for this study is 1 kg of produced yogurt. The input and output data were collected from various sources like reports, databases, legislation. All these data were used further in the impact assessment stage performed with GaBi software which includes LCA methods like CML2001 - Jan. 2016, ReCiPe 1.08, UBP 2013, EDIP 2003 and others. Results showed that the global warming potential (GWP) determined for yogurt was 2.92 kg CO2 eq. per kg of yogurt, while acidification potential (AP) was approximately 0.014 kg SO2 eq. per kg of yogurt. It was observed that the main contributor to all impact categories is consumption of electricity during the yogurt production, mainly in the pasteurization, evaporation and cooling stages. 61.4% of the emissions resulted from transportation of raw materials contributes to GWP, while 38.3% to photochemical ozone creation potential (POCP). Emissions from wastewater treatment are contributing especially to the eutrophication potential (EP), while emission from solid waste landfilling are contributing mainly to POCP.

Abstract
This study was conducted to investigate the impact of introducing Saccharomyces cerevisiae with or without molasses in a diet based on rice husk on the health status of goats. Thirty (30) West African Dwarf (WAD) goats with mean weight of 10.46 ± 0.06 kg were randomly allotted to five dietary treatments of six goats per treatment in a completely randomized design experiment for 84 days. The goats were fed five formulated diets of rice husks anaerobically fermented for 7days with S. cerevisiae with or without molasses at graded levels. Nutrient composition of feed, daily nutrient intake, apparent digestibility coefficients, weekly weight gain/change by the goats were evaluated. At the end of the feeding trial, faeces, urine and blood samples were collected and analysed using standard procedures. The efficacy of the diet containing a combination of S. cerevisiae and molasses in ratio 1:1 as a feed additive, coupled with fermentation was proven by the concomitant reduction in fibre content. All the growth criteria (feed intake, live weight gain and feed conversion ratio), blood profiles and serum minerals measured favoured goats fed this Diet 3. No mortality was recorded during the trial. Conclusively, introducing S. cerevisiae with molasses at equi-ratio nutritionally enhances optimal rice husk utilization in goats’ nutrition and supported productive performance and their health status.

Abstract
Grape seed cakes (GSC) resulted from grape seed oil extraction represent a by-product rich in bioactive compounds such as polyphenols, polyunsaturated fatty acids, fibres, minerals, vitamins etc known for their beneficial anti-inflammatory, anti-microbial, anti-oxidative and immune-modulatory effects. In the present study, we have investigated the effects of dietary grape seed cakes bioactive compounds on several anti-inflammatory and antioxidative biomarkers in spleen of pigs during fattening phase. Twelve crossbred TOPIG hybrid fattening pigs were allocated to two experimental treatments: 1) commercial diet (control group) and 2) a diet including 5% grape seed cakes (GSC group) for 24 days. At the end of experimental period (day 24) pigs were sacrificed and spleen samples were collected and stored at –80°C until analysis. The results showed that GSC diet lowered the gene expression as well as the protein concentration of pro-inflammatory markers: interleukin 1 beta (IL-1β, -52.66%, p<0.05) and interferon gamma (IFN-γ, -42.13%, p<0.05) and had a tendency to decrease that of interleukin 6 (IL-6, -13.25%), tumour necrosis factor alpha (TNF-α, -9.06%) and interleukin 8 (IL-8, -11.08%) when compared to control diet confirming the anti-inflammatory properties of GSC’s active ingredients. The total splenic antioxidant capacity (TEAC) and gene expression of antioxidant enzymes (catalase-CAT and glutathione peroxidase-GPx) were higher in spleen of pigs fed GSC diet than in control group suggesting also the antioxidative potential of GSC. The results related to the molecular mechanism showed a higher expression of gene encoding for PPAR-γ and for Nrf2 in spleen of pigs receiving the GSC diet (Fc 1.81 and 1.58) suggesting that the anti-inflammatory and antioxidant effect of this diet is probably exerted by PPAR-γ and Nrf2 pathway. Further, other percent of dietary GSC inclusion need to be investigated in order to obtain a more complex response related to biomarkers which characterise the fattening/obesity process.

Abstract
In the concept of alternative tourism, the dynamic growth of cultural tourism can be explained by the fast growth of demand for trips to various cultural attractions and amenities. Alternative tourism is a form of tourism that is not well-known and promoted in our country, but which presents high economic development potential. Alternative tourism is based on the use of natural potentials and cultural heritage and encourages interaction with nature, people and community. Peja District is an important tourist destination in Kosovo especially in rural areas, which are popular and frequently visited by local visitors and tourists from the European Union. History, culture and tradition are the main sources of tourism development in Peja region. The position of extension, the protected environment, the fertile lands, etc. are the elements that identify the city of Peja as a tourist town, which is visited throughout the year by visitors from different countries. Such tourism will be just green, sensitive, progressive, harmonious, responsible, eco, community; all characteristics fall under the heading “alternative tourism”. The goal of the paper is to provide readers with knowledge about alternative tourism in Peja municipality.

New Perspectives in Developing the Balance Scorecard Concept
Authors: Marcu Gheorghe 
Published: November 2020

Abstract
The main role for researchers and organizational theorists is to translate their statements and principles into practical tools applicable in the management activity. Sometimes, these tools used in managerial practice are not rigorously developed and applied, some eventually contradicting the initial assumptions. However, most of the times, the concepts go through a natural cycle of developing, harmonizing and refining their own statements and demonstrations, with the support of the authors and / or other researchers. Also, the manifestation in management of any action that claims the increase of the performances in the financial or non-financial fields must be accompanied by a set of measuring and evaluation tools. Robert Kaplan and David Norton are best known as the originators of the Balanced Scorecard (BSC) concept which adds to the managerial equation the imperative necessity of aligning the individual and organizational effort with the organizational vision and strategic objectives, in a whole defined by four perspectives: financial, customer and stakeholder, internal processes and organizational capacity of learning and growth. Balanced Scorecard is a concept used in private and public sector organizations, used to point / highlight the vision, missions, strategic goals of an organization, to evaluate the performance of strategic management and to be used as a tool as well effective internal communication. Over the time, like any other concept in the field of social sciences, BSC goes through a continuous process of adaptation and improvement of its own statements, methods and tools.

Abstract
In the context of conflicts and threats specific to the security environment generated by the political, military, economic, social, technological and cultural challenges, as well as the obvious threat of the new COVID-19 virus to public health presented in the previous subchapter, we consider it imperative that we understand both the role of the military organization and the process by which the list of essential requirements for fulfilling the mission of the military organization is identified and established (Mission Essential Task List-METL). The identification of the relevant tactical scenarios, built on real facts extracted from the current world context, the analysis of the combat capacity of the subunits contributes to the realistic and adequate elaboration of a framework for the missions of the subunits.
Mycorrhizal symbiosis of alien and invasive tree species
Authors: Wilgan Robin 
Published: November 2020

AbstractThe introduction of alien tree species has become a world wide phenomenon over the last centuries and the cultivation of these species is an economically important branch of forestry in many countries. However, the cultivation of alien plant species poses the threat of introducing potentially invasive species, both trees and its mutualistic symbionts, such as mycorrhizal fungi. Mycorrhizal fungi are obligatory symbionts and a key element in the proper development and functioning of trees. It is thought that mycorrhizal fungi may also profoundly influence the invasiveness of alien tree species worldwide, with the proper fungal species acting as a driver to make this invasion possible. Co-invasion of alien trees and its mutualistic symbionts are well-known in the case of pines and co-invading ectomycorrhizal fungi in the southern hemisphere.Invasive tree species constitute a major ecological and economic problem through intense competition and modification of local habitats leading to a decline in biodiversity and potentially threatening many rare, native and endangered species, including fungi. Despite the fundamental role that fungi have in the functioning of forests, the impact alien tree species could have on mycorrhizal fungi in native forest ecosystems has not received much attention.Understanding the relationships between mycorrhizal fungi and alien tree species can allow us to better predict and counter- act alien species invasions, which is necessary in order to maintain biodiversity and preserve native ecosystems. On top of that, climate change could threaten some European tree species and thus free ecological niches for other species, like alien, invasive or potentially invasive trees.
