University-School clusters: Best practices and the prospects for their adaptation to Ukrainian context : the XVIII International Scientific and Practical Conference (14-th Febuary 2020, Kharkiv Univ. of Humanities “People’s Ukrainian Acad”.
Clustering of education is one of the answers to the challenges of today.
The concept of "clustering" was first introduced in the 1950s mainly in the industrial sector, and in the late twentieth century it became widespread in the social sphere.
Clusters are now becoming a key component of national and regional economic development plans.
Kharkiv region is the center of implementation of educational clusters in the active role of higher education institutions, which constantly seek to improve the quality of training of competitive specialists. Work experience in the educational cluster has been accumulated at the Kharkiv Physics and Mathematics Lyceum # 27, the main purpose of which is the education and development of gifted and capable pupils.
The institution has a system of work with pupils, which involves teachers of higher educational institutions, students. The extra classes’ activities for students are held at the Center for Pre-University Education of Kharkiv National University.
In our view, the significant potential in overcoming and minimizing the negative factors that influence the self-realization of gifted students and do not facilitate their "participation" in the development of human capital is in the creation of educational clusters. They envisage the cooperation of various persons who interact with gifted students.

University-School clusters: Best practices and the prospects for their adaptation to Ukrainian context : the XVIII International Scientific and Practical Conference (14-th Febuary 2020, Kharkiv Univ. of Humanities “People’s Ukrainian Acad”.
This article addresses the problems of implementing cluster models in world educational practices. They are analyzed based on the understanding of the educational cluster as a set of interconnected educational institutions, which are united by industry and partnership.
There are different types of educational clusters: educational (lyceum – college – university / university complex); mixed (scientific-educational, industrial-educational), etc. – depending on the specific implementation of cluster theory in different countries. On the basis of generalization of world practices, the presence of conditional models of cluster formation on national and regional grounds is demonstrated.
The basic characteristics, general tendencies of forming of partnership relations which can become the basis of activity of educational clusters in Ukraine are revealed:
The results of this analysis can be used in the design and implementation of cluster policy, aimed at improving the competitiveness of educational institutions.

Published: May 2021

The Practical guideline is based on the current scientific ESPEN guideline on Clinical Nutrition in Liver Disease (Plauth M., Bernal W., Dasarathy S., Merli M., Plank L. D., Schütz T., Bischoff S. C. ESPEN guideline on clinical nutrition in liver disease // Clin Nutr. — 2019. — 38. — Р. 485—521). It has been shortened and transformed into flow charts for easier use in clinical practice.

The guideline is dedicated to all professionals including physicians, dieticians, nutritionists and nurses working with patients with chronic liver disease. A total of 103 statements and recommendations are presented with short commentaries for the nutritional and metabolic management of patients with (i) acute liver failure, (ii) alcoholic steatohepatitis, (iii) non-alcoholic fatty liver disease, (iv) liver cirrhosis, and (v) liver surgery/transplantation. The disease-related recommendations are preceded by general recommendations on the diagnostics of nutritional status in liver patients and on liver complications associated with medical nutrition. This practical guideline gives guidance to health care providers involved in the management of liver disease to offer optimal nutritional care.
Adult Intuitions about Mechanistic Content in Elementary School Science Lessons
Authors: Betz Nicole , McCarthy Amanda , Keil Frank
Published: May 2021

Elementary schools provide students with their first encounters with formal science, creating both foundations for students’ knowledge of science content, and impressions of what it means to learn science. Here, we examined adult, including K12 teachers’, intuitions regarding different types of content relevant to elementary school science, namely, labels, function, and mechanism. We focused primarily on perceptions of mechanistic explanations—causal explanations that explain how something works. This focus stems from children’s curiosity and aptitude for mechanism. Across four studies we predicted, and found, that participants deprioritize mechanistic explanations relative to more superficial explanation types: labels and function. This intuition, which appears to be reflected in formal science curricula, misestimates children’s abilities and attitudes towards mechanistic information.
Association of State-Issued Mask Mandates with COVID-19 Case Counts
Authors: Mitteldorf Josh , Setty Madhava
Published: May 2021

We have interpreted and extended an analysis published on the US CDC website 5 March 2021, which calculated the benefits of imposed mask mandates. Historical studies of masking in the general population have produced contradictory results with respect to their effectiveness in stemming spread of respiratory viral infections. The CDC study is based on a comparison of Daily Growth Rate (DGR) in number of COVID cases (or deaths) before and after imposition of mask mandates. We show that the downward trend in DGR began before masking and continued after masking. We add controls to the CDC methodology by comparing states that imposed mask mandates to states that did not. We report evidence of short-term benefit for the first 30 days that is lost when DGR increased in the fall more in masked states than unmasked. Overall, we find that the benefits reported by CDC can be completely explained by saturation effects, weather changes, and other factors apart from the government mandates that the study was designed to evaluate.
Ostracods, Charophytes, and Pollen from the Baynunah Formation
Authors: Mazzini Ilaria , Kovacova Marianna
Published: May 2021

Ostracods, charophytes and pollen were retrieved from sediments of the Baynunah Formation. Autoecological characteristics of the ostracods and the charophytes, together with detailed observations on the taphonomy of ostracod valves, provide a reconstruction of the depositional environments of the Baynunah freshwater system. These microfossil assemblages indicate the presence of a large floodplain with a slow-flowing river with high suspended sediment load, as well as a system of shallow, possibly isolated, water bodies with clear waters and submerged meadows of macroalgae. The water bodies were characterized by fluctuating salinities that could be linked to phases of evaporation-desiccation and regeneration of the freshwater environment, i.e. alternation of humid and dry periods. Pollen remains indicate associations of herbaceous plants typical of open woodland to grassland habitats, with halophytes growing close to the water bodies.
Large-scale study of speech acts' development using automatic labelling
Authors: Nikolaus Mitja , Maes Juliette , Auguste Jeremy , Prévot Laurent , Fourtassi Abdellah
Published: May 2021

Studies of children's language use in the wild (e.g., in the context of child-caregiver social interaction) have been slowed by the time- and resource- consuming task of hand annotating utterances for communicative intents/speech acts. Existing studies have typically focused on investigating rather small samples of children, raising the question of how their findings generalize both to larger and more representative populations and to a richer set of interaction contexts. Here we propose a simple automatic model for speech act labeling in early childhood based on the INCA-A coding scheme (Ninio et al., 1994). After validating the model against ground truth labels, we automatically annotated the entire English-language data from the CHILDES corpus. The major theoretical result was that earlier findings generalize quite well at a large scale. Our model will be shared with the community so that researchers can use it with their data to investigate various questions related to language use development.
Some like it sharp: Song familiarity influences musical preference for absolute tuning
Authors: Van Hedger Stephen Charles , Bongiovanni Noah , Khudhair Huda
Published: May 2021

Listening to music is an enjoyable activity for most individuals, yet the factors that relate to aesthetic preferences are not completely understood. In the present paper, we investigate whether the absolute tuning of music influences listener evaluations of music. Across three experiments, participants rated musical excerpts, tuned conventionally (A4 = 440 Hz) versus unconventionally (± 50 cents from conventional tuning), in terms of aesthetic preference. In Experiment 1, participants rated single MIDI piano excerpts on each trial in terms of liking, interest, and unusualness. In Experiments 2 and 3, participants heard two versions of the same excerpt on each trial, only differing in terms of tuning, and made a forced-choice judgment as to which version they preferred. Experiment 2 used the same piano excerpts as Experiment 1, whereas Experiment 3 introduced both highly familiar and unknown song excerpts by professional recording artists. Overall, the results suggest that absolute tuning influences aesthetic preferences under limited circumstances. Although there was no strong evidence for tuning influencing judgments in either Experiments 1 or 2, we found a robust effect in Experiment 3 depending on the familiarity of the recording. Whereas participants clearly preferred the conventionally tuned version for highly familiar recordings, they tended to prefer the version that was highest in absolute pitch if the recording was unfamiliar. Overall, these results suggest that absolute tuning can influence musical preferences, although the specific nature of the effect depends on familiarity.
Homeworking Project Management & Agility as the New Normal in a Covid-19 World
Authors: Sonjit Patcharin , Dacre Nicholas , Baxter David
Published: May 2021

The Covid-19 global pandemic crisis has had a deep and profound impact on fundamental elements of society, the economy, and the environment as a whole. Key organisations, businesses, sectors and industries vital for delivering crucial projects have been affected by the relatively fast onset of Covid-19 on a global scale. As a result, organisational routines and project management processes that would have focused on established methods and practices have incurred dramatic changes leading to a greater emphasis on agility as part of a more exhaustive strategic Covid-19 world, where new routines and processes become embedded as the new normal. This research focuses on the increased demand in Homeworking Project Management (HPM) and more significant agility requirements across dispersed virtual project management teams. Initial insights from semi-structured interviews with a cross-section of 12 high-level project professionals suggest that; (i) Transitional homeworking project management processes have a direct impact on collaborative and operational routines; (ii) There is a greater level of demand on agility with HPM teams which do not necessarily have the organisational infrastructure to support these, (iii) Technological resources are becoming a primary concern with inequality of information across HPM teams, and (iv) Increasing critical bottlenecks across dispersed HPM teams is adversely affecting tenable project outcomes.
Applied Algorithmic Machine Learning for Intelligent Project Prediction: Towards an AI Framework of Project Success
Authors: Hsu Ming-Wei , Dacre Nicholas , Senyo PK
Published: May 2021

A growing number of emerging studies have been undertaken to examine the mediating dynamics between intelligent agents, activities, and cost within allocated budgets, in order to predict the outcomes of complex projects in dint of their significant uncertain nature in achieving a successful outcome. For example, prior studies have used machine learning models to calculate and perform predictions. Artificial neural networks are the most frequently used machine learning model with support vector machine, and genetic algorithm and decision trees are sometimes used in several related studies. Furthermore, most machine learning algorithms used in prior studies generally assume that inputs and outputs are independent of each other, which suggests that a project's success is expected to be independent of other projects. As the datasets used to train in prior studies often contain projects from different clients across industries, this theoretical assumption remains tenable. However, in practice projects are often interrelated across several different dimensions, for example through distributed overlapping teams. An ongoing ethnographic study at a leading project management artificial intelligence consultancy, referred to in this research as Company Alpha, suggests that projects within the same portfolio frequently share overlapping characteristics. To capture the emergent inter-project relationships, this study aims to compare two specific types of artificial neural network prediction performances; (i) multilayer perceptron and; (ii) recurrent neural networks. The multilayer perceptron has been found to be one of the most widely used artificial neural networks in the project management literature, and recurrent networks are distinguished by the memory they take from prior inputs to influence input and output. Through this comparison, this research will examine whether recurrent neural networks can capture the potential inter-project relationship towards achieving improved performance in contrast to multilayer perceptron. Our empirical investigation using ethnographic practice-based exploration at Company Alpha will contribute to project management knowledge and support developing an intelligent project prediction AI framework with future applications for project practice.

Published: May 2021

Background: Achalasia Cardia is a rare esophageal motility disorder. Among various treatment options, Pneumatic Dilatation (PD) is the most widely used and cost effective modality till date. This is the first observational study aiming to evaluate the short term response and complications of PD for Achalasia Cardia in Nepal.

Methods: This prospective observational study was conducted between 28th Jan 2020 to 27th Jan 2021. It included 39 patients with Achalasia Cardia diagnosed by clinical presentation, esophagoscopy, barium esophagogram and high resolution manometry. Two patients of Type III achalasia were excluded from study. Thirty seven patients underwent pneumatic dilatation with 30 mm Rigiflex balloon (Boston Scientific, USA) for a duration of 1 minute. Response was assessed by Eckardts score at 3 and 6 months.

Result: Among 39 cases (mean age= 39.03±15.017 years, 59% men), commonest was Type II Achalasia (71.8%) followed by Type I (23.1%) and Type III (5.1%). Dysphagia was present in all patients (100%), followed by weight loss (84.6%), regurgitation (79.5%) and chest pain (35.9%). Mean basal Eckardts score and Lower Esophageal Sphincter pressure of the study population was 7.81±1.24 and 24.40±6.83 respectively. Response to pneumatic dilatation was 89.2%. Eckardts score changed significantly from7.81±1.24 to 1.03±1.82 at 6 months (p<0.001). None of the patients had major complications. Younger age (23±6.377 years) had poor response to treatment, while predilatation Lower Esophageal Sphincter pressure, gender and type of achalasia did not affect the treatment outcome.

Conclusion: PD is safe and effective treatment modality for Achalasia. Younger patients have poor response to treatment with Pneumatic Dilatation.

Published: May 2021

Background Diabetic peripheral neuropathy (DPN) is a significant independent risk factor for diabetic foot, and an effective screening instrument is required to diagnose DPN early to prevent future ulceration and amputation. This study aims to determine the diagnostic accuracy of monofilament test to detect diabetic peripheral neuropathy.

Methods This cross-sectional study was conducted in National Academy of Medical Sciences, Bir hospital, Mahabouddha, Kathmandu from February 2016 to January 2017. A total of 96 diabetic patients attending inpatient and outpatient Department were selected. Diabetic peripheral neuropathy was assessed by measurement of loss of protective sensation (LOPS) by monofilament test and compared with vibration perception threshold by standard biothesiometer. The sensitivity, specificity, positive predictive value and negative predictive value of monofilament test were calculated.

Results The prevalence of diabetic peripheral neuropathy was 26%. The sensitivity, specificity, positive predictive value and negative predictive value of monofilament test were found to be 92.0%, 95.8%, 88.5% and 97.1% respectively. There was strong association between LOPS by monofilament and vibration perception threshold by biothesiometer.

Conclusion This study showed a strong diagnostic accuracy of monofilament test to detect DPN when compared with biothesiometer. As monofilament test is a cheap, easily available, and portable, it can be used in the periphery where biothesiometer is not available.
Three Classical Methods to find the Cube Roots: A Connective Perspective on Lilavati, Vedic and Pande's Procedures
Authors: Parajuli Krishna Kanta
Published: May 2021

South Asian region has made a glorious history of mathematics. This area is considered as fer- tile land for the birth of pioneer mathematicians who developed various mathematical ideas and creations. Among them, three innovative personalities are Bhaskaracarya, Gopal Pande and Bharati Krishna Tirthaji and their specific methods to find cube root are mainly focused on this study. The article is trying to explore the comparative study among the procedures they adopt.

Gopal Pande disagrees with the Bhaskaracarya's verse. He used the unitary method against that method mentioned in Bhaskaracarya's famous book Lilavati to prove his procedures. However, the Vedic method by Tirthaji was not influenced by the other two except for minor cases. In the case of practicality and simplicity, the Vedic method is more practical and simpler to understand for all mathematical learners and teachers in comparison to the other two methods.
Monte Carlo Method to Solve Diffusion Equation and Error Analysis
Authors: Shrestha Samir
Published: May 2021

Three different mathematical approaches for the evolution of diffusion equation are presented. The evolution process of the diffusion equation is explained by principle of conservation law, probability distribution procedure, and finally though stochastic differential equation (SDE) driven by Brownian motion. The Monte Carlo method is discussed to solve the diffusion equation by generating the normally distributed random numbers and the root mean square error is derived for the Monte Carlo method. The numerical solutions are computed for 1-dimensional diffusion equation and results are compared with exact solution. Finally, theoretical root mean square error is compared with the maximum error and the L2-error by increasing the number of simulated points.

Effect of organic fertilization doses on forage palm production
 
ABSTRACT: The forage palm represents an excellent cultivation alternative for the Brazilian semi-arid, as it adapts well to the region's edaphoclimatic conditions. The objective of this work was to evaluate the morphometric characteristics and the productivity of two species of forage palm submitted to different doses of organic fertilization. The experimental design used was in randomized blocks in a 4 x 2 factorial scheme, with 4 replications, with four doses of organic fertilization and two species. The characteristics evaluated were: length of the cladode, width of the cladode, number of cladodes, plant height, total height of the cladodes, area of ​​the cladode, index of the area of ​​the cladodes, production of green mass and production of dry mass. The data were subjected to analysis of variance. The Tukey test (P <0.05) was used to compare the means of the species and for fertilizer doses, graphs were generated from the regressions. For the morphometric and production characteristics, a significant effect was observed for the doses of bovine manure under all parameters analyzed. Maximum dry matter production was observed when 75 t ha-1 of bovine manure was applied. The ‘Gigante’ palm has a higher production of dry matter when compared to ‘Sem espinho’.

Determination of Protein C Antigen Levels in Hospitalized Patients with Blood Coagulative Defects
Authors: Zhu George
Published: May 2021

Protein C, a vitamin K-dependent anticoagulant serine protease, is involved in blood coagulation. Activated protein C inactivates Va and VIIIa in purified protein systems and stimulates fibrinolysis by indirectly increasing the level of circulating plasminogen activator. In this process, protein S serve as an important factor for activated protein C. In recent years, excess protein S drives cancer cell proliferation and cell survival through oncogenic receptor Axl (Anexelekto). We determined changes of plasma protein C antigen by using rocket immunoassay both in 50 healthy individuals and 103 distinct hospitalized patients. In healthy individuals protein C antigen(PC:Ag) ranges o.6439- 1.4752 µ/ml. The results showed that plasma protein C antigen was considerably high in 22 diabetes mellitus. In contrast, the PC:Ag was significantly decreased in 19 liver cirrhosis(p< 0.001) and in closely line with serum albumin levels(p< 0.05). In 31 acute leukemias, on the average, there was slightly lower values in PC:Ag, and accompanied with the distribution of significant decrease of PC:Ag values in 5 FAB M5 subtype and in 9 hyperleukocytic leukemias. However, the 3 acute promyelocytic leukemia (APL) with overt laboratory criteria of disseminated intravascular coagulation (DIC) had protein C concentration no lower than the remaining 2 patients with infectious DIC, which suggested the coagulopathy in APL might be due to mechanisms different from other forms of DIC.
The Limits of Knowing Other Minds
Authors: McKearney Patrick
Published: May 2021

New care workers in Britain typically struggle to understand, on their initial encounters, people who communicate atypically due to their intellectual disabilities. But they are required to provide care that is attuned to these individuals’ desires and intentions. Why, then, does a care organization called L’Arche UK make it harder for carers to learn what is going on inside these people’s minds? I argue that doing so does not prevent the acquisition of essential knowledge, but rather trains new carers to relate to those with intellectual disabilities as opaque. This creates a more involved relationship that opens up the possibility of forms of status and intimacy otherwise closed to such people—thereby raising questions about the supposedly fundamental role that transparency and knowledge play in knowing others.
Leaving the Field in the Digital Age
Authors: Girke Felix
Published: May 2021

Anthropologists’ arrival stories have long served to justify, naturalize, and domesticate—often through humor—the fraught moment of entering unasked into other people’s lives. This textual convention has been thoroughly critiqued, but no comparable attention has been paid to the analogous moment of departure from the field. The digital age enables both sides to maintain contact, a shift that negates the finality of earlier departures. This article engages the changes wrought by digital media that allow us to remain connected to the field. While this seems a humane affordance, it also means that it is no longer feasible to cleanly sever ties established ‘there’. When anthropologists leave the field, the field will likely follow them—on Facebook or Instagram.

Published: May 2021

OBJECTIVE

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an established neurosurgical treatment for the motor symptoms of Parkinson’s disease (PD). While often highly effective, DBS does not always yield optimal therapeutic outcomes, and stimulation-induced adverse effects, including paresthesia, muscle contractions, and nausea/lightheadedness, commonly occur and can limit the efficacy of stimulation. Currently, objective metrics do not exist for monitoring neural changes associated with stimulation-induced therapeutic and adverse effects.

METHODS

In the present study, the authors combined intraoperative functional MRI (fMRI) with STN DBS in 20 patients with PD to test the hypothesis that stimulation-induced blood oxygen level–dependent signals contained predictive information concerning the therapeutic and adverse effects of stimulation.

RESULTS

As expected, DBS resulted in blood oxygen level–dependent activation in myriad motor regions, including the primary motor cortex, caudate, putamen, thalamus, midbrain, and cerebellum. Across the patients, DBS-induced improvements in contralateral Unified Parkinson’s Disease Rating Scale tremor subscores correlated with activation of thalamic, brainstem, and cerebellar regions. In addition, improvements in rigidity and bradykinesia subscores correlated with activation of the primary motor cortex. Finally, activation of specific sensorimotor-related subregions correlated with the presence of DBS-induced adverse effects, including paresthesia and nausea (cerebellar cortex, sensorimotor cortex) and unwanted muscle contractions (caudate and putamen).

CONCLUSIONS

These results suggest that DBS-induced activation patterns revealed by fMRI contain predictive information with respect to the therapeutic and adverse effects of DBS. The use of fMRI in combination with DBS therefore may hold translational potential to guide and improve clinical stimulator optimization in patients.

Published: May 2021

OBJECTIVE

Status epilepticus (SE) is associated with significant mortality, cost, and risk of future seizures. In one of the first studies of SE after neurosurgery, the authors assess the incidence, risk factors, and outcome of postneurosurgical SE (PNSE).

METHODS

Neurosurgical admissions from the MarketScan Claims and Encounters database (2007 through 2015) were assessed in a longitudinal cross-sectional sample of privately insured patients who underwent qualifying cranial procedures in the US and were older than 18 years of age. The incidence of early (in-hospital) and late (postdischarge readmission) SE and associated mortality was assessed. Procedural, pathological, demographic, and anatomical covariates parameterized multivariable logistic regression and Cox models. Multivariable logistic regression and Cox proportional hazards models were used to study the incidence of early and late PNSE. A risk-stratification simulation was performed, combining individual predictors into singular risk estimates.

RESULTS

A total of 197,218 admissions (218,217 procedures) were identified. Early PNSE occurred during 637 (0.32%) of 197,218 admissions for cranial neurosurgical procedures. A total of 1045 (0.56%) cases of late PNSE were identified after 187,771 procedure admissions with nonhospice postdischarge follow-up. After correction for comorbidities, craniotomy for trauma, hematoma, or elevated intracranial pressure was associated with increased risk of early PNSE (adjusted OR [aOR] 1.538, 95% CI 1.183–1.999). Craniotomy for meningioma resection was associated with an increased risk of early PNSE compared with resection of metastases and parenchymal primary brain tumors (aOR 2.701, 95% CI 1.388–5.255). Craniotomies for infection or abscess (aHR 1.447, 95% CI 1.016–2.061) and CSF diversion (aHR 1.307, 95% CI 1.076–1.587) were associated with highest risk of late PNSE. Use of continuous electroencephalography in patients with early (p < 0.005) and late (p < 0.001) PNSE rose significantly over the study time period. The simulation regression model predicted that patients at high risk for early PNSE experienced a 1.10% event rate compared with those at low risk (0.07%). Similarly, patients predicted to be at highest risk for late PNSE were significantly more likely to eventually develop late PNSE than those at lowest risk (HR 54.16, 95% CI 24.99–104.80).

CONCLUSIONS

Occurrence of early and late PNSE was associated with discrete neurosurgical pathologies and increased mortality. These data provide a framework for prospective validation of clinical and perioperative risk factors and indicate patients for heightened diagnostic suspicion of PNSE.

OBJECTIVE

The main goal of preventive treatment of unruptured intracranial aneurysms (UIAs) is to avoid the morbidity and mortality associated with aneurysmal subarachnoid hemorrhage. A comparison between the conservative approach and the surgical approach combining endovascular treatment and microsurgical clipping is currently lacking. This study aimed to conduct an updated evaluation of cost-effectiveness comparing the two approaches in patients with UIA.

METHODS

A decision tree with a Markov model was developed. Quality-adjusted life-years (QALYs) associated with living with UIA before and after treatment were prospectively collected from a cohort of patients with UIA at a tertiary center. Other inputs were obtained from published literature. Using Monte Carlo simulation for patients aged 55, 65, and 75 years, the authors modeled the conservative management in comparison with preventive treatment. Different proportions of endovascular and microsurgical treatment were modeled to reflect existing practice variations between treatment centers. Outcomes were assessed in terms of QALYs. Sensitivity analyses to assess the model’s robustness and completed threshold analyses to examine the influence of input parameters were performed.

RESULTS

Preventive treatment of UIAs consistently led to higher utility. Models using a higher proportion of endovascular therapy were more cost-effective. Models with older cohorts were less cost-effective than those with younger cohorts. Treatment was cost-effective (willingness to pay < 100,000 USD/QALY) if the annual rupture risk exceeded a threshold between 0.8% and 1.9% in various models based on the proportion of endovascular treatment and cohort age. A higher proportion of endovascular treatments and younger age lowered this threshold, making the treatment of aneurysms with a lower risk of rupture more cost-effective.

CONCLUSIONS

Preventive treatment of aneurysms led to higher utility compared with conservative management. Models with a higher proportion of endovascular treatment and younger patient age were most cost-effective.

Despite significant contributions of vegetable and flower production to the improvement of the livelihoods of household producers in the Central Highlands of Vietnam, several challenges facing the development of this sector require a general evaluation. This study aimed at assessing the current situation and economic efficiency of flowers and vegetables and analyzing the application of production techniques on the cultivation of these crops. Based on secondary data sources combined with a primary survey of 144 vegetable farmers and 74 flower growers in all five provinces (Lam Dong, Dak Lak, Dak Nong, Kon Tum, and Gia Lai) of the area in 2018, descriptive statistics and economic values were applied to provide an overview of the development of vegetable and flower production of the region. Findings showed that there were large differences in yields and economic efficiencies of vegetables and flowers among the five provinces of the Central Highlands. Accordingly, the yields and economic efficiencies of vegetables and flowers in Lam Dong were two to five times higher than those in other provinces (Dak Lak, Dak Nong, Kon Tum, and Gia Lai). In addition, the applications of technological advances in vegetable and flower production remained limited. Major challenges for flower and vegetable development included the lack of irrigation water, weak capabilities of building flower and vegetable brands, and limitations in market access. Solutions to improve production technology implications, develop brands of high-quality products, and raise the ability to access market for all vegetable and flower stakeholders are highly recommended.

Resting egg production of rotifers provides critical advantages in larviculture of most fish species due to the reduction in the costs of labour and algae production. The study was conducted to investigate the effects of temperature on population growth and resting egg production of a freshwater rotifer, Brachionus calyciflorus, collected in Northern Vietnam. The rotifer was pre-cultured at 27ºC before being transferred to the cultures at 15 and 35ºC while the control was maintained at 27ºC. One-liter beakers filled with 500mL culture medium were used with three replicates for each temperature group. Stock rotifers were inoculated at an initial density of 200 ind ml-1 and fed with concentrated fresh algae. The results indicated that population growth rate (r) of rotifers cultured at 27 and 35ºC were significantly higher than that of rotifers at 15ºC while the highest density was attained from the treatment of 27ºC, at 608.3 ind mL-1, compared to 468.3 and 360.5 ind mL-1 at 35 and 15ºC, respectively. Transferring the cultures from 27 to 35ºC significantly increased the rate of resting egg carrying females with the maximum rate of 31.5% compared to 21.2 and 13.5% of the rotifers at 27 and 15ºC, respectively. The resting egg densities of the cultures at 35ºC were also significantly higher than those at 15 and 27ºC. The resting egg carrying females appeared and increased their rates in concurrence with increases in the population density. The present results are important information for resting egg induction and production of rotifer in larviculture.

Land resources potential assessment is a valuable method for orienting land use planning in the world as well as in Vietnam.The objectives of the study are (1) to assess land suitability and (2) to orient the effective use of agricultural land in the study area. Results indicated that Ham Thuan Bac has 107 land mapping units (LMU), in which includes 11 land-use types (LUTs) such as rice, corn, cassava and sweet potato, sugarcane, grass for livestock, vegetables, green dragon fruit, rubber, coffee, and other fruit trees. Agricultural land with high suitability (S1) and moderately suitable (S2) for mostly LUTs is small, however, marginally suitable (S3) and not suitable land (N) are quite large. More than 50% of the LUTs for growing rice, rubber, coffee, other fruit are not suitable; the remaining LUTs have unsuitable land ranging from 10.76% to 25.16% of agricultural land in the district. Based on land suitability classification, we propose to keep 8550 ha with S1, S2, and a part of S3 area to be irrigated for cultivating rice; 9071.7ha of dragon fruit land including 694.67 ha of S1 and 8377.03 ha of S2 land; and only cultivate annual crops, fruit trees and grazing grass on the land with suitble levels from S1 to S3 of the current status.The remainingareas ofS3 and N for riceand areas of S2 and S3for green dragon fruit under S2, S3with active and semi-active irrigation regimeswill be converted to annual crops and fruit trees and grass for livestock.
