Effect of changes in forest water balance and inferred root reinforcement on landslide occurrence and sediment generation following Pinus radiata harvest on Tertiary terrain, eastern North Island, New Zealand
Authors: Marden Michael , Rowan Donna , Watson Alex
Published: March 2023

Background: The frequent occurrence of storm-initiated landslides following harvesting of Pinus radiata D.Don in steep, Tertiary terrain, East Coast region, North Island, New Zealand, is of increasing concern. This paper documents the influence of tree removal and of replacement plantings on the canopy water balance and soil moisture regime when slopes are at their most vulnerable to landslide occurrence.
Methods: At a previously established study site, rainfall, throughfall, and soil moisture data were collected before a mature stand of P. radiata was harvested. After harvesting, part of the study site was replanted with P. radiata at 1000 stems ha-1 and part with 500 stems ha-1. Relationships between hydrological changes and landslide occurrence are discussed in relation to planting density, site factors, root system development, silvicultural regimes, and alternative land use options for mitigating erosion in highly erodible hill country.
Results: Following harvesting, soil moisture levels remained higher for longer than under a mature forest until rainfall interception and evapotranspiration returned to pre-harvest levels. This coincided with canopy closure, irrespective of planting density. After thinning, interception and evapotranspiration decreased, then regained the equivalent of a closed canopy 2 years later. Landslide occurrence was highest on slopes >25° and with a NE aspect. Sediment generation rates were highest in 2─4-year-old plantings, then decreased markedly with increasing tree age.
Conclusions: Irrespective of planting density, P. radiata had little influence on the soil-water regime until canopy interception, evapotranspiration rates, soil-drying and recharge cycles returned to pre-harvest levels, coinciding with canopy closure. During this period, pore-water pressures at times of heavy or prolonged rainfall likely result in soil saturation and an increase in landslides. The progressive loss of root strength of the harvested trees had a secondary influence. The duration of the post-harvest period of heightened slope vulnerability to landslide initiation is a function of the combined influences of site factors on rates of tree growth and survival, and of the planting density regime on the canopy water balance and soil water content until the development of an effective live soil-root reinforcement system. For areas identified as high risk, the targeting of high-value timber species with longer rotation length, including consideration of coppicing species, would minimise the risk of slope failure at harvest. Very high-risk areas unsuited to rotational harvesting will ultimately require transitioning to a permanent indigenous forest cover.

Published: March 2023

Termites are very well recognized by farmers as pests and beneficial insects. To develop management options suitable to the needs of the farmers, it is essential to understand their management experience. This study was aimed at understanding farmer’s perception about termite management in eastern Uganda. The study covered over 84 villages located in seven districts of eastern Uganda. There were 420 respondents for the survey and a focus group discussion (comprised of eight to 15 participants) specifically with push-pull technology adopters found in four districts. Quantitative and qualitative data were collected and analyzed using STATA (version 13). Respondents were diverse in terms of age, gender, level of education and marital status.  According to the respondent’s termite damage can cause food insecurity and poverty. The prevalence of termites and damage potential varies across districts and type of crop and growth stage. Some are vulnerable at germination, some at vegetative and some at maturity stages. Averaged over three districts, farmers claimed that maize is more vulnerable to termite attack causing about 40% yield loss followed by beans, soybeans, and sorghum. Push-pull technology adopters stated that green leaf desmodium intercropped with maize to control major lepidopteran pests and a parasitic weed striga was vulnerable to termite attack. Although pesticide application can be an effective option, they claimed it is either expensive or not a lasting solution.

Authors: Ali Shoukat , Safdar Umair
Published: March 2023

Agriculture Officers working in Agriculture Department (Extension) are perceived lacking in professional competencies. One of the root causes of this problem lies in the mismatched eligibility criteria for the post of Agriculture Officer (Extension). The purpose of this paper was to discuss the relevancy of the Extension Agents’ competencies with their job responsibilities for policy implications. The universe of the study was Punjab Province of Pakistan. The cross-sectional design was used for the study. All Agriculture Officers (public extension agents) work in the Agriculture Department (Extension), Government of Punjab were the population of the study. Multistage simple random sampling technique was used for drawing the sample. A sample of 60 respondents was drawn from sampling frame by using simple random sampling technique. A desktop study was also conducted to analyze the contents offered to the currently eligible agricultural graduates during their pre-service training at the university level. Results showed that only 3.3% of the respondents had relevant pre-service training. About 58% of the Agriculture Officers (Extension) were not satisfied with their jobs and most of them were thinking to change their jobs. This study has practical implications for Punjab Public Service Commission, Lahore and Agriculture Department (Extension) Government of Punjab, Pakistan in particular. The research theorized that the duties of extension work should only be entrusted to the professionals having per-service training in agricultural extension. Otherwise, the efficiency of the agricultural extension system would be compromised. This is the first study of its kind in which the eligibility criteria of the Agriculture Officers (Extension) have been questioned in the Punjab, Pakistan. The finding and discourse of the study would initiate the debate among stakeholders to place right person for the right job. The materialization of study findings would enhance the efficiency of Agricultural Extension system.

Published: March 2023

Bardawil Lake is considered one of the most important and purest Egyptian lakes. However, in recent years, a relative decrease in the quantity and value of production and a qualitative change has been observed in the fish produced by the lake. Hence, this study aimed to identify the most important problems facing the fishermen in Bardawil Lake and their suggestions to overcome them. This study was conducted in North Sinai Governorate, Data were collected using a focus group discussion method with 90.6% of the board's members of fishing associations (58 respondents). in addition, A random sample of 346 fishermen through a personal interview from May to December 2020. The results indicated the high age levels of fishermen (X̅ = 50.44) and the high illiteracy rate among them (58.57%) despite their high experience in the fishing profession, but unfortunately, it was not based on a training background as 69.65% of the respondent fishermen did not receive any training courses. only 13.45% of them depended on the agricultural extension as the main source of technical information, which indicates a clear absence of the agricultural extension role with the fishermen in the lake. The most important obstacles facing the respondent fishermen were the weak income from the fishing profession 89.88%, the weak role of agricultural extension 86.42%, the insufficiency of the role of fishing cooperatives 83.82%, While their most important suggestions were to activate the laws regulating the fishing process 90.17% and to prevent illegal fishing 84.68%. The study recommends developing fish extension and providing it with specialists in the fields of fisheries development to play a more effective role in this field.

Published: March 2023

This study analyzed the effects of the COVID-19 pandemic on household income and the determinants of coping strategies in Nigeria, using the combination of the COVID-19 National Longitudinal Phone Survey data and the fourth wave of the General Household Survey, Panel 2018-2019.  The fourth wave of General Household Survey, Panel 2018-2019 data is part of the World Bank's Living Standards Measurement Study–Integrated Surveys on Agriculture (LSMS-ISA) and the National Bureau of Statistics of Nigeria collected the data in collaboration with the World Bank and funded by the Federal Government of Nigeria and the Bill and Melinda Gates Foundation. The COVID-19 National Longitudinal Phone Survey 2020, Baseline was implemented by the National Bureau of Statistics in collaboration with the World Bank. The analyses were based on multinomial logistic and multivariate probit models. Multinomial logit regression analysis shows that households that consider the pandemic a substantial threat and households with older heads were more likely to have decreased income while households that received transfer income and self-employed were more likely to have increased income. Several household characteristics exhibited different levels of influence on the choice of coping strategies during the lockdown. Therefore, policy options and support facilities should be developed to foster meaningful (wage/self) employment and coping strategies to achieve optimal results in response to the pandemic.
Purinergic P2X7 Receptor as a Potential Targeted Therapy for COVID-19-associated Lung Cancer Progression
Authors: Zalpoor Hamidreza , Akbari Abdullatif , Nabi-Afjadi Mohsen , Norouzi Ali , Seif Farhad , Pornour Majid
Published: March 2023

Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection is a serious threat to lung cancer patients. Hereby, we hypothesize that Coronavirus disease 2019 (COVID-19) may contribute to lung cancer progression by increasing extracellular adenosine triphosphate (ATP) levels and hyperactivating the purinergic P2X purinoceptor 7 receptor (P2X7R). Hyperactivation of P2X7R by increased extracellular ATP may stimulate multiple signaling pathways and factors such as NLRP3 inflammasome; as a result, interleukin (IL)-1β, and IL-18 pro-inflammatory cytokines are released, JNK, Rho kinase, HMGB1-RAGE, PI3K/AKT, hypoxia-inducible factor-1 alpha (HIF-1α), and ERK. NLRP3 activation may play a pivotal role in fatal cytokine storm in critically ill patients with COVID-19 and tumor progression in patients with lung cancer. Consequently, inhibiting these signaling pathways may deviate immune responses toward anti-tumoral responses, and suppress lung cancer progression and cytokine storms. Therefore, targeting P2X7R by means of oxidized ATP and anti-P2X7 monoclonal antibodies may provide promising therapeutic approaches to prevent lung cancer progression in COVID-19 patients; however, no clinical trials have yet been conducted, and their clinical efficacy remains to be elucidated.

Among the different compounds present in the must, nitrogen is an essential nutrient for the management of fermentation kinetics, also playing a major role in the synthesis of fermentative aromas. Fermentation temperature is yet another variable that affects fermentation duration and the production of fermentative aromas in wine. The main objective of this study was thus to evaluate the combined effects of nitrogen addition—at the start of the fermentation process or during the stationary phase—at different fermentation temperatures on both fermentation kinetics and aroma synthesis kinetics. To study the impact of these three parameters simultaneously, we used an innovative transdisciplinary approach associating an online GC-MS system with an original modeling approach: a Box-Behnken experimental design combined with response surface modeling and GAM modeling. Our results indicated that all three factors studied had significant effects on fermentation and aroma production kinetics. These parameters did not impact in the same way the different families of volatile compounds. At first, obtained data showed that reduction of ester accumulation in the liquid phase at high temperature was mainly due to important losses by evaporation but also to modifications of yeast metabolic capabilities to synthetize these compounds. In a noticeable way, optimal temperature changed for liquid accumulation of the two classes of esters—23°C for acetate ester and 18°C for ethyl esters—because biological impact of temperature was different for the two chemical families. Moreover, the study of these three factors simultaneously allowed us to show that propanol is not only a marker of the presence of assimilable nitrogen in the medium but above all a marker of cellular activity. Finally, this work enabled us to gain a deeper understanding of yeast metabolism regulation. It also underlines the possibility to refine the organoleptic profile of a wine by targeting the ideal combination of fermentation temperature with initial and added nitrogen concentrations. Such observation was particularly true for isoamyl acetate for which interactions between the three factors were very strong.
Effects of thriving at work on employees’ family role performance: A moderated mediation model
Authors: Yang Baoyan , Su Shaoqing , Zong Zhaobiao , Du Qiaoqiao , Wang Junyi
Published: March 2023

Objective

Existing research has demonstrated that thriving at work has a positive effect on work performance, but little is known about how thriving at work affects family role performance. Based on the work–home resource model, this study examines the impact mechanism of thriving at work on family role performance.

Methods

This paper uses an experience sampling method to conduct a 5-day daily study of 151 married employees in Northwest China, and the data were analyzed using a multilevel linear model.

Results

We find that thriving at work positively affects family role performance partly through the mediating effect of work–family enrichment at the individual level. Moreover, family-supportive supervisor behavior moderates the relationship between thriving at work and work–family enrichment. Through work–family enrichment, family-supportive supervisor behavior also moderates the indirect relationship between thriving at work and family role performance. Specifically, the higher the level of family-supportive supervisor behavior, the stronger the indirect effect of thriving at work on family role performance through work–family enrichment.

Conclusion

Previous research has focused more on the effects of thriving at work within the work domain, suggesting that thriving at work can have a positive impact on work outcomes. However, only a few studies have examined the positive relationship between thriving at work and family role performance from the perspective of employees’ positive psychological resources. This paper explores the positive effects of thriving at work on family role performance based on a resource flow perspective and identifies its potential boundary conditions. This study enriches the theoretical research on the relationship between thriving at work and family role performance. Additionally, it provides a new foothold and research perspective on improving work–family enrichment.
Speech error rates after a sports-related concussion
Authors: Patel Sona , Grabowski Caryn , Dayalu Vikram , Testa Anthony J.
Published: March 2023

Background

Alterations in speech have long been identified as indicators of various neurologic conditions including traumatic brain injury, neurodegenerative diseases, and stroke. The extent to which speech errors occur in milder brain injuries, such as sports-related concussions, is unknown. The present study examined speech error rates in student athletes after a sports-related concussion compared to pre-injury speech performance in order to determine the presence and relevant characteristics of changes in speech production in this less easily detected neurologic condition.

Methods

A within-subjects pre/post-injury design was used. A total of 359 Division I student athletes participated in pre-season baseline speech testing. Of these, 27 athletes (18–22 years) who sustained a concussion also participated in speech testing in the days immediately following diagnosis of concussion. Picture description tasks were utilized to prompt connected speech samples. These samples were recorded and then transcribed for identification of errors and disfluencies. These were coded by two trained raters using a 6-category system that included 14 types of error metrics.

Results

Repeated measures analysis of variance was used to compare the difference in error rates at baseline and post-concussion. Results revealed significant increases in the speech error categories of pauses and time fillers (interjections/fillers). Additionally, regression analysis showed that a different pattern of errors and disfluencies occur after a sports-related concussion (primarily time fillers) compared to pre-injury (primarily pauses).

Conclusion

Results demonstrate that speech error rates increase following even mild head injuries, in particular, sports-related concussion. Furthermore, the speech error patterns driving this increase in speech errors, rate of pauses and interjections, are distinct features of this neurological injury, which is in contrast with more severe injuries that are marked by articulation errors and an overall reduction in verbal output. Future studies should consider speech as a diagnostic tool for concussion.

Published: March 2023

The development of rational dosage forms with cetirizine is an urgent task. Cetirizine is a second-generation antihistamine. In patients suffering from allergies, the use of cetirizine leads to a significant improvement in the course of the disease. Even in veterinary practice, taking cetirizine orally once a day provides sufficient antihistamine effect in animals. Currently, the following drugs with cetirizine are available: film-coated tablets, orodispersible tablets, as well as drops for oral administration. There are no transdermal dosage forms with cetirizine in Russia. The transdermal therapeutic system (TTS) is a metered-dose soft dosage form for external use in the form of gels, patches, or films, which releases the drug slowly. The TTS advantages are as follows: ease of use, the ability of the medicinal substance to quickly enter the bloodstream, the ability to regulate the release rate of the active substance and use hydrophilic and lipophilic substances. We have developed two transdermal therapeutic systems with cetirizine — a gel and a patch, and studied the pharmacological effects. The purpose of the study. The purpose of this work is to create external dosage forms containing cetirizine. The scientific novelty of the research is the design of formulations for antiallergic dosage. Materials and methods. Technological and pharmacological research methods were used. Results. The study showed that the developed gel and the patch with cetirizine have antiallergic properties comparable to the comparison drug (Psilo-balsam gel), while surpassing the reference drug in its effect on the formation of allergic exudative edema. Conclusion. External dosage forms — a transdermal therapeutic gel and a patch containing cetirizine have been created.
Why Does Arctic Sea Ice Respond More Evidently than Antarctic Sea Ice to Climate Change?
Authors: Shokr Mohammed , Ye Yufang
Published: March 2023

The current climate change episode has impacted sea ice in the 2 polar regions differently. In the Arctic, remarkable sea ice extent and thickness declines have been observed with a stunning depletion rate of old ice. No similar changes have been observed in the Antarctic. In this paper, the question posed in the title is addressed by reviewing findings retrieved from previous publications. The paper starts by identifying key geographic and climatic features and sea ice characteristics in the 2 polar regions and summarizing relevant recent records. It then proceeds by investigating interactions between sea ice and environmental factors, including atmospheric, oceanic, and dynamic aspects in each region, as well as the increasing number of icebergs in Antarctica. It is concluded that peculiarities of each polar region render the response to climate change differently. Researchers should not apply scenarios regarding the impacts of climate change on Arctic sea ice (i.e., retreat) to Antarctic sea ice. Instead of asking why Antarctic sea ice has not responded to climate change in the same way as Arctic ice, a more reasonable question could be why Arctic ice changes are yielding an annual cycle that resembles that of Antarctic ice. Under current global warming conditions, old ice entrapment within the Arctic basin is relaxed. This could result in Arctic sea ice becoming predominantly seasonal during winter and almost completely melted during summer, which is the current state of Antarctic sea ice.
Real-World COVID-19 Vaccine Protection Rates against Infection in the Delta and Omicron Eras

Published: March 2023

The real-world vaccine protection rates (VPRs) against the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) infection are critical in formulating future vaccination strategies against the virus. Based on a varying coefficient stochastic epidemic model, we obtain 7 countries’ real-world VPRs using daily epidemiological and vaccination data, and find that the VPRs improved with more vaccine doses. The average VPR of the full vaccination was 82% (SE: 4%) and 61% (SE: 3%) in the pre-Delta and Delta-dominated periods, respectively. The Omicron variant reduced the average VPR of the full vaccination to 39% (SE: 2%). However, the booster dose restored the VPR to 63% (SE: 1%) which was significantly above the 50% threshold in the Omicron-dominated period. Scenario analyses show that the existing vaccination strategies have significantly delayed and reduced the timing and the magnitude of the infection peaks, respectively, and doubling the existing booster coverage would lead to 29% fewer confirmed cases and 17% fewer deaths in the 7 countries compared to the outcomes at the existing booster taking rates. These call for higher full vaccine and booster coverage for all countries.

Published: March 2023

Infusion pumps and syringe pumps are devices used to administer liquid medicines to patients. The frequency of using the infusion pump and syringe pump in the long term will affect the accuracy of the tool. Accuracy is very important in dosing to patients in critical conditions who require intensive care to prevent fluid balance in the body. Therefore, periodic calibration of medical devices is required at least once a year. Calibration according to Permenkes No. 54 of 2015 is a calibration activity to determine the correctness of a tool. The purpose of this research is to make an Infusion Device Analyzer (IDA) with a TFT LCD displaying a graph of flowrate parameters. The method used is to analyze the flowrate value using an infrared photodiode sensor and can see the stability of the flowrate graph on a 7-inch TFT LCD from the use of 2 brands of syringes and an infusion set. The results obtained can be stored on the SD Card. The measurement results show that the error in the performance of the syringe and infusion pump read by the module on Channel 1 with the Terumo syringe is 0.15 (10 ml/h), 0.1 (50ml/h) and 0.03 (100ml/h). . On Channel 2 it is 0.02(10ml/hour), 0.03 (50ml/hour) and 0.04(100ml/hour). When using the B-Braun Channel 1 syringe, 0.25 (10ml/h), 009(50ml/h) and 0.08(100ml/h) are used. And on Channel 2 it is 0.62 (10ml/h), 0.15 (50ml/h), and 7.3 (100ml/h). When using the Terumo Channel 1 brand infusion set at 0.05 (10ml/h), 0.3(50ml/h), and 0.04(100ml/h). On Channel 2 it is 0.14(10ml/hour), 0.02 (50ml/hour) and 0.18 (100 ml/hour). When using the B-Braun Channel 1 Infusion Set, it is 0.07(10ml/h), 0.02(50 ml/h), and 0.03 (100ml/h). Then on Channel 2 0.07 (10ml/hour), 0.02(50 ml/hour), and 0.1(100ml/hour). The conclusion of this study is that the use of 2 different infusion sets greatly affects the readings, other than that other factors can also affect the readings including the position of the hose and the placement of sensors on each channel. From the manufacture of this tool, it is expected that users can be more efficient in using a 2-channel Infusion Device analyzer which can be run at the same time.

In December 2019, the world was introduced to a new coronavirus, severe acute respiratory syndrome (COVID-19).The primary strategy for COVID-19 patients is supportive care, using high-flow nasal oxygen therapy (HFNC) reported to be effective in improving oxygenation. Stability is the ability of a medical device to maintain its performance [1]. Medical equipment must have the stability necessary to maintain critical performance conditions over a period of time. Accuracy is the closeness of agreement between the value of a measuring quantity, and the value of the actual quantity of the measuring quantity[2].The purpose of this study is to ensure that the readings of the HFNC device are accurate and stable so that it is safe and comfortable when used on patients. The development of the equipment that will be used by the author adds graphs to the TFT LCD to help monitor stable data in real time so that officers can monitor the flow and fraction of oxygen in the device to be stable. This study uses Arduino Nano while the sensor used is the GFS131 sensor, then the results are displayed on the Nextion TFT LCD. The test is carried out with comparing the setting value of the HFNC tool that appears on the TFT LCD with a gas flow analyzer with a measurement range of 20 LPM to 60 LPM 5 times at each point. Based on measurements on the gas flow analyzer, the HFNC module has an average error (error (%)) of6.40%. Average uncertainty (Ua) 0.05. Conclusion from these results that the calibrator module has a relative error (error value) that is still within the allowable tolerance limit, which is ±10%, the tool is precise because of the small uncertainty and good stability of the stability test carried out within a certain time.

Sport is a physical activity that can optimize body development through muscle movement. Physical activity without rest with strong and prolonged muscle contractions results in muscle fatigue. Muscle fatigue that occurs causes a decrease in the work efficiency of muscles. Electrocardiography (ECG) is a recording of the heart's electrical activity on the body's surface. EMG is a technique for measuring electrical activity in muscles. This study aims to detect the effect of muscle fatigue on cardiac signals by monitoring ECG and EMG signals. This research method uses the Maximum Heart Rate with a research design of one group pre-test-post-test. The independent variable is the ECG signal when doing plank activities, while the dependent variable is the result of monitoring the ECG signal. To get the Maximum Heart Rate results, respondents use the Karnoven formula and perform the T-test. Test results show a significant value (pValue <0.05) in pre-exercise and post-exercise. When the respondent experiences muscle fatigue, it shows the effect of changes in the shape of the ECG signal which is marked by the presence of movement artifact noise. It concluded that the tools in this study can be used properly. This study has limitations including noise in the AD8232 module circuit and the display on telemetry where the width of the box cannot be adjusted according to the ECG paper.is  It recommended for further research to use components with better quality and replace the display using the Delphi interface.

The use of palm kernel meal and coconut meal is restriction in broiler feed due to the high crude fiber content, caused by the mixture of shells. This study aims to analyze the nutrient content, i.e., crude protein and crude fiber of palm kernel meal and coconut meal before and after using wet separation and molecular weight approach. The wet separation process for palm kernel meal and coconut meal was carried out for 6 hours to obtain a precipitate. The palm kernel meal and coconut meal that have been separated is divided into 3 fractions, i.e., upper, middle and lower. Each fraction was analyzed for crude fiber and crude protein content for chemical characteristics, and bulk density (g l-1), compacted bulk density (g l-1), specific gravity (kg l-1), angle of purpose (o). Crude protein and crude fiber content of palm kernel meal before being separated by wet separation were 11.72% and 13.11%, for coconut meal were 12.65% and 8.67%. The fraction of palm kernel meal has the highest crude protein content of 22.21% with the lowest crude fiber content 9.68%. Coconut meal in the middle fraction had the highest crude protein content 18.92% and the lowest crude fiber content of 11.95% in the upper fraction. The physical characteristics of the upper fraction of palm kernel meal and coconut meal had the lowest values (P0.05) of specific gravity (kg l-1), bulk density (g l-1) and compacted bulk density (g l-1). It can be concluded that the wet separation process with the molecular weight approach is able to increase the nutrient content especially of each fraction and can minimize the mixture of shells in palm kernel meal and coconut meal

For Georgia, the post-pandemic period turned out more positive than expected. Since the spring of 2022, the pandemic has been declared virtually over, which has significantly reduced the country's budget for the fight against Covid-19, completely lifted restrictions on the tourism sector, renewed the production process, and created new expectations to overcome the crisis exacerbated during the pandemic. Georgia has made significant progress in terms of improving the financial sector and developing sound monetary and financial regulations, however, inflationary processes continue and place a heavy burden on citizens and the business sector affected by the pandemic. The agenda was to develop the right macroeconomic policy, develop an appropriate strategy and ensure sustainable growth.

The article discusses the main challenges of the post-pandemic economy in Georgia and ways to overcome them.
