With the development of information and computer technology, it is possible to monitor and analyze on-line features of large steam turbine-generator units. The energy consumption rate and the exhaust steam dryness are two important indices. Base on the analyses of those existed calculation methods for turbine varying condition, we give a sequential varying condition calculation that starts with steam extraction of the final stage or the second final stage (superheated steam condition). According to the initially assumed final stage flow, and the thermodynamic parameters before the final stage, also the backpressure, we can distinguish the flow patterns of the stage by a discriminant criteria. Then we can conduct a stage varying condition calculation of primary stage in sequence from the front final stage parameter, so the new exhaust steam enthalpy and the exhaust steam dryness can be got. So the precise energy consumption rate and the exhaust enthalpy (or the dryness) can be got easily. Obviously, without measuring the flow or the dryness, we can accurately monitor the on-line energy consumption rate and the dryness of the units.

In this paper, the temperature vegetation dryness index （TVDI） method and thermal inertia index method are designated as the way of modeling drought monitoring in Fuxin. First, the temperature vegetation dryness index and the thermal inertia index are obtained by means of the parameters. Then with soil water content data measured actually at meteorological stations in Fuxin, the empirical models of Temperature Vegetation Dryness Index–Soil Water Content (TVDI-SWC) and apparent Thermal Inertia-Soil Water Content (ATI-SWC) are established. After regression analysis and forecasting analysis of 2006, the results clearly show that the ATI-SWC model generally outperforms TVDI-SWC model on prevernal drought monitoring in Fuxin. It can be used for quick and exact estimation of the whole drought condition of Fuxin.

Central Asian countries, which are included the Mid-Latitude Region (MLR), need to develop regional adaptive strategies for reducing Sand and Dust Storm (SDS)-induced negative damages based on adequate information and data. To overcome current limitation about data and assessment approaches in this region, the macroscale verified methodologies were required. Therefore, this study analyzed environmental conditions based on the SDS impacts and regional differences of SDS sources and receptors to support regional SDS adaptation plans. This study aims to identify environmental conditions based on the phased SDS impact and regional differences of SDS source and receptor to support regional adaptation plans in MLR. The Normalized Difference Vegetation Index (NDVI), Aridity Index (AI), and SDS frequency were calculated based on satellite images and observed meteorological data. The relationship among SDS frequency, vegetation, and dryness was determined by performing statistical analysis. In order to reflect phased SDS impact and regional differences, SDS frequency was classified into five classes, and representative study areas were selected by dividing source and receptor in Central Asia and East Asia. The spatial analysis was performed to characterize the effect of phased SDS impact and regional distribution differences pattern of NDVI and AI. The result revealed that vegetation condition was negatively correlated with the SDS frequency, while dryness and the SDS frequency were positively correlated. In particular, the range of dryness and vegetation was related to the SDS frequency class and regional difference based on spatial analysis. Overall, the Aral Sea and the Caspian Sea can be considered as an active source of SDS in Central Asia, and the regions were likely to expand into potential SDS risk areas compared to East Asia. This study presents the possibility of potential SDS risk area using continuously monitored vegetation and dryness index, and aids in decision-making which prioritizes vegetation restoration to prevent SDS damages with the macrolevel approach in the MLR perspective.

The most significant risk for viticulture is that the sugar content of the grapes will increase in the future due to rising temperatures. As a result, it will be possible to produce wines with increasing alcohol content in the future. Excessively high alcohol content can significantly reduce the wines’ marketability and viticulture’s profitability. Our study seeks to answer how the expected drought in the Southern and Central regions of Europe will affect the future change in the sugar content of grapes. The degree of dryness was examined using the dryness index in the study. Finally, it was analyzed how the dryness index affects the past and future occurrence of maximum sugar content for six grape varieties. The probability of the occurrence of maximum sugar content for most vine grape varieties will decrease in the near future. However, in the distant future, there is a likelihood that the occurrence of maximum sugar content will increase again. If we can maintain the DI ≥ −10 condition with regulated deficit irrigation, the probability of the occurrence of maximum sugar content may decrease significantly in the near future. Ensuring moderate dryness is the only way to achieve the proper sugar content.

Under immersed and we-dry cyclic conditions, the deterioration processes of the organic coating on carbon steel surface have been comparatively studied using electrochemical techniques. The wet-dry cycles were carried out by exposure to 4 h immersion and 4h dryness (4-4h cycles) and 12h immersion and 12h dryness (12-12h cycles) conditions, respectively. The immersion condition was carry out in a 3.5% NaCl solution and drying at 298K and 50% RH. According to the EIS characteristics, the entire deterioration processes under above three mentioned conditions can be divided into three main stages, consisting of the medium penetration, corrosion initiation and corrosion extension. Comparing with the immersed, the 4-4h wet-dry cycles greatly accelerated the entire deterioration process; especially during the corrosion initiation and the corrosion extension periods, leading the paint system lose its anti-corrosive performance in a short period. However, the 12-12h wet-dry cycles decelerated the entire deterioration process, prolonging the coatings anticorrosive ability. The acceleration mechanism of the coatings and underlying metal corrosion under wet-dry cycles was discussed based on the above results.

Abstract. Understanding changes in background dryness over land is key information for adapting to climate change because of its critical socioeconomic consequences. However, causes of continental dryness changes remain uncertain because various climate parameters control dryness. Here, we verify dominant climate variables determining dryness trends over continental eastern Asia, which is characterized by diverse hydroclimate regimes ranging from arid to humid, by quantifying the relative effects of changes in precipitation, solar radiation, wind speed, surface air temperature, and relative humidity on trends in the aridity index based on observed data from 189 weather stations for the period of 1961–2010. Before the early 1980s (1961–1983), change in precipitation is a primary condition for determining aridity trends. In the later period (1984–2010), the dominant climate parameter for aridity trends varies according to the hydroclimate regime. Drying trends in arid regions are mostly explained by reduced precipitation. In contrast, the increase in potential evapotranspiration due to increased atmospheric water-holding capacity, a secondary impact of warming, works to increase aridity over the humid monsoon region despite an enhanced water supply and relatively less warming. Our results show significant drying effects of warming over the humid monsoon region in recent decades; this also supports the drying trends over warm and water-sufficient regions in future climate.

Yeast mannan (YM) is an indigestible water-soluble polysaccharide of the yeast cell wall. In vitro fecal fermentation studies showed that YM could exhibit a notable prebiotic effect. The aim of this randomized, double-blind, placebo-controlled study was to assess the efficacy of YM intake on the intestinal environment and skin condition. One hundred and ten healthy female subjects aged 30–49 years were supplemented with YM or placebo for eight weeks. Skin dryness was set as the primary endpoint. No side effects were observed during the study. Microbiota analyses revealed that YM intake selectively increased the relative abundance of Bacteroides thetaiotaomicron and Bacteroides ovatus compared to that by placebo. Feces and urine analyses showed that YM intake lowered the concentration of fecal p-cresol, indole, and skatole, and elevated urinal equol levels compared to those in placebo. Furthermore, YM supplementation ameliorated subjective skin dryness. This study suggests that YM intake could promote beneficial Bacteroides and improve the intestinal environment and skin condition.

Agriculture is one of the dominant industries in the Mun River Basin, but farmlands are frequently affected by floods and droughts due to the water resource management mode of their rainfed crop, especially in the context of climate change. Drought risk assessment plays an important role in the Mun River Basin’s agricultural sustainable development. The objective of this study was to identify the tempo-spatial variation in dryness and wetness patterns; the drought intensity, frequency, and duration; and the potential causes behind drought using the methods of the standardized precipitation evapotranspiration index (SPEI), ensemble empirical mode decomposition (EEMD), correlation analysis, and the Pettitt test over the basin. Results showed that the Mun River Basin underwent a drying climate pattern, which is explained by the significant decreasing trend of SPEI_12M during the study period. In addition, the downstream area of the Mun River Basin was subjected to more intense, extreme dryness and wetness events as the decreased amplitude of SPEI_12M and SPEI_3M was higher than that over the upper and middle reaches. Drought intensity presented a remarkable decadal variation over the past 36 years, and an average 7% increase per decade in the drought intensity was detected. Besides, there have been more mild and moderate droughts frequently appearing over the Mun River Basin in recent decades. For the underlying causes behind the drought condition, on the one hand, the shortened precipitation day over the rainy season accounted more for the intense drought events than the precipitation amount. On the other hand, El Nino Southern Oscillation (ENSO)-brought sea surface temperature anomalies aggravated the potential evapotranspiration (ETr), which might be closely related to the drought intensity and frequency variation. These tempo-spatial maps of dryness and wetness and drought occurrence characteristics can be conducive to local stakeholders and agricultural operators to better understand the agriculture industry risks and vulnerabilities and properly cope with pre-disaster planning and preparedness and post-disaster reconstruction over the Mun River Basin.

Cognitive performance is essential to foster learning. High CO2 concentrations are common in classrooms and can lead to reduced cognitive performance. Negative air ions (NAIs) can improve cognitive performance. This study explored the effects of indoor NAIs on the cognitive performance and health of college students exposed to a high pure CO2 environment. Forty college students were exposed to four sets of conditions (NAIs+500 ppm CO2, 500 ppm CO2, NAIs+2500 ppm CO2, and 2500 ppm CO2). Participants’ cognitive performance, including reasoning, short-term memory, concentration, and verbal ability, was assessed under each condition using the Cambridge Brain Sciences tool. Acute health symptoms were investigated using a subjective questionnaire, and simultaneously, participants’ blood pressure, heart rate, and lung function were tested. Analysis of variance (ANOVA) in a repeated-measures design was used to analyze the effects of different conditions on cognitive performance and health symptoms. The results revealed that the different levels of CO2 and NAIs had a significant effect on cognitive performance after one hour of exposure and had no significant effect after three hours of exposure. Compared with 500 ppm CO2, 500 ppm CO2+NAIs resulted in better reasoning skills, short-term memory, and verbal skills, and 2500 ppm CO2 led to poorer reasoning skills. The addition of NAIs to 2500 ppm CO2 improved reasoning skills, short-term memory, and verbal skills. The benefits of adding NAIs to high pure CO2 condition on cognitive performance are more noticeable than those to low CO2 condition. Moreover, adding NAIs can reduce nasal irritation or dryness, skin irritation or dryness, sleepiness symptoms, and heart rate elevation caused by pure CO2. However, the benefits of NAIs on health symptoms and physiology were not observed under the 500 ppm CO2 condition. Adding NAIs to a high pure CO2 level is an effective means to improve the cognitive performance and health of college students.

The objective of this paper is to improve our perception of drought in central Sudan. This has been realized by detailing the changes that occurred in the dryness ratio (rainfall/potential evapotranspiration) of the United Nations Environment Programme (UNEP) during the period 1941–2005. Eight representative stations of the area were selected and their dryness ratios examined on annual and monthly bases. A trend towards intensifying and more recurrent drought has been found. This trend is particularly significant in the arid areas. Statistically significant increase in areal coverage of drought has occurred. Substantial changes took place in the severity and frequency of drought between 1941–1970 and 1971–2005 over the whole area. Moreover, the early to mid-1970s, mid-1980s, early 1990s and early 2000s were determined as common drought years and were among the driest 10 years. The analysis also revealed high and generally increasing inter-annual variability of the dryness ratio. There is not a dominant short-term persistence in the data, as assessed by the lag-one serial correlation coefficient. Early forecast of the moisture condition during the rest of the season could merely be accomplished at small scale in the area. These results indicate that drought in the study area is irregular.

Background: Autoimmune thyroid disease (AITD) is an inflammatory condition that primarily affects women between the ages of 30 and 50. It has been hypothesised that AITD causes salivary glands to produce less saliva due to its endocrine effects. Studies showing the effect of AITD on salivary glands are very scarce. The aim of this study was to compare AITD patients with controls who were of a similar age and gender in terms of salivary metrics and the prevalence of dental caries. Methods: 200 subjects in Bangalore city (100 AITD subjects and 100 healthy subjects as controls) participated in a cross-sectional study. Subjective oral dryness was assessed using Farsi’s criteria. Salivary parameters and caries were assessed using GC Saliva-Check BUFFER kit and WHO caries criteria respectively. Descriptive and analytical statistics were done. Significant data was defined as a p value of <0.05. Results: When compared to controls, the AITD group had substantially more subjective mouth dryness and dental caries. Unstimulated (USFR) and stimulated salivary flow rate (SFR), pH and buffering capacity were reduced in AITD group whereas viscosity was high. There was a significant negative correlation between USFR, SFR, subjective oral dryness and dental caries. In a linear regression, there was no association between age, gender, socioeconomic status (SES), thyroid stimulating hormone (TSH), salivary viscosity, pH, buffering capacity and dental caries. Dental caries, USFR and SFR demonstrated a substantial relationship. Conclusions: The present research may indicate an underlying association between thyroid and salivary gland dysfunction resulting in oral dryness and high dental caries experience.

The net ecosystem CO2 exchange (NEE) is a critical parameter for quantifying terrestrial ecosystems and their contributions to the ongoing climate change. The accumulation of ecological data is calling for more advanced quantitative approaches for assisting NEE prediction. In this study, we applied two widely used machine learning algorithms, Random Forest (RF) and Extreme Gradient Boosting (XGBoost), to build models for simulating NEE in major biomes based on the FLUXNET dataset. Both models accurately predicted NEE in all biomes, while XGBoost had higher computational efficiency (6~62 times faster than RF). Among environmental variables, net solar radiation, soil water content, and soil temperature are the most important variables, while precipitation and wind speed are less important variables in simulating temporal variations of site-level NEE as shown by both models. Both models perform consistently well for extreme climate conditions. Extreme heat and dryness led to much worse model performance in grassland (extreme heat: R2 = 0.66~0.71, normal: R2 = 0.78~0.81; extreme dryness: R2 = 0.14~0.30, normal: R2 = 0.54~0.55), but the impact on forest is less (extreme heat: R2 = 0.50~0.78, normal: R2 = 0.59~0.87; extreme dryness: R2 = 0.86~0.90, normal: R2 = 0.81~0.85). Extreme wet condition did not change model performance in forest ecosystems (with R2 changing −0.03~0.03 compared with normal) but led to substantial reduction in model performance in cropland (with R2 decreasing 0.20~0.27 compared with normal). Extreme cold condition did not lead to much changes in model performance in forest and woody savannas (with R2 decreasing 0.01~0.08 and 0.09 compared with normal, respectively). Our study showed that both models need training samples at daily timesteps of >2.5 years to reach a good model performance and >5.4 years of daily samples to reach an optimal model performance. In summary, both RF and XGBoost are applicable machine learning algorithms for predicting ecosystem NEE, and XGBoost algorithm is more feasible than RF in terms of accuracy and efficiency.

In the development of inflammatory diseases of the pharynx, etiological factors may include viral agents, bacterial infection, mainly streptococcal nature, fungal infection, diseases of the gastrointestinal tract (GERD, gastritis). Inflammatory changes in the oral mucosa and pharynx can be manifested by the main symptoms such as a feeling of dryness in the mouth and throat, difficulty or pain when swallowing. Xerostomy is a condition that develops when saliva secretion decreases or stops and is characterized by dryness in the oral cavity. With long-term course is accompanied by psycho-emotional disorders and contributes to the development of dental diseases (stomatitis, gingivitis). Septolete total including substances such as cetylpyridinium chloride and benzidamine, has antimicrobial and anti-inflammatory and can be used as an effective etiotropic and pathogenetic therapy of inflammatory diseases of the pharynx. It is also possible to use after otorhinolaryngological interventions(tonsilectomy).

The aim of study is to develop highly reliable and less time consuming steam dryness fraction measuring experimental setup. This method of dryness fraction measurement is based on throttling process which is obtained by using orifice plate. Calculation of orifice diameter was done by using ISO 5167 for given pressure drop. This paper deals with the conceptual design of orifice in a steam pipe line. The objective of the conceptual design is to obtain throttling process. Three parameters are chosen for the conceptual design: the diameter of the orifice, the aspect ratio between length and diameter and the entrance angle to the orifice. This work also deals with validation of calculated orifice diameter through CFD simulation for pressure drop in pipe line. To simulate the throttling process, the inlet condition of the orifice upstream flow is fixed at 10 bar and 180°C. The temperature and pressure is measured at the outlet of the orifice while steam is flowing through the pipe. An orifice diameter of 11.00mm is selected as the optimal value to keep throttling process. The resulting optimal orifice design will be used in steam pipe line.

The precursor of LiNi0.5MnSubscript text1.5O4cathode material with high density was synthesized by two-dryness co-precipitation method. The optimized parameters were found out by studying the relationship between the density of precursor and the concentration of reactants, the manner of adding agglomerating agent, the remaining water in filter cake and the manner of dryness. The highest density (1.74 g/cm3) of precursor can be achieved under optimized condition: NiSO40.375 mol/L, coagulation agent added with little amount but many times, 28% of water in filter cake and two-step dryness, which is much better than that made by other methods. Our experiment provides a significant reference for the synthesis of excellent-performance cathode materials of lithium-ion battery. LiNi0.5MnSubscript text1.5O4has a good cycle performance, a higher discharge capacity and a discharge platform of 4.7v, so it has become a research focus of 5-voltage cathode materials in the field of lithium ion battery recently.[1-4] However, LiNi0.5Mn1.5O4 prepared by common methods usually has a lower tap volume capacity.[5-9] HiroyuKi Ito[6] reported a continuous fabricated high-density cobalt-manganese-doped nickel hydroxide method with which the density of product was between 1.5-1.91g/cm3, however the used ammonia as a complexation agent in the preparation process not only increased the cost of the preparation, but also led to environmental pollution. Research results show that the cathode material synthesized using high-density precursor has a higher tap density, a larger volume capacity and a good electrochemical performance.[10] In this paper, we find out the optimized parameters of preparation of precursor of LiNi0.5MnSubscript text1.5O4by studying the relationship between the density of precursor and concentration of reactants, the manner of adding agglomerating agent, the remaining water in filter cake and the manner of dryness.

Abstract: Forest fires have devastating effects on extensive forest areas, compromising vital ecological services such as air purification, water conservation, and recreational opportunities, thus posing a significant socioeconomic threat. Furthermore, the risk of forest fires is steadily increasing due to climate change. The most effective method for mitigating forest fire risk is proactive prevention before forest fires can occur by identifying high-risk areas based on land surface conditions. This study aimed to develop a machine learning-based forest fire diagnostic model designed for South Korea, considering both satellite-derived land surface data and anthropogenic factors. For the remote sensing data, VTCI (Vegetation Temperature Condition Index) was used to reflect the land surface dryness. In addition, fire activity maps for buildings, roads and cropland were used to consider the influence of human activities. The forest fire diagnostic model yielded an accuracy of 0.89, demonstrating its effectiveness in predicting forest fire risk. To validate the effectiveness of the model, 92 short-term forest fire risk forecast maps were generated from March to May 2023 with real-time data on forest fire occurrences collected for verification. The results showed that 73% of forest fires were accurately classified within high-risk zones, confirming the operational accuracy of the model. Through the forest fire diagnostic model, we have presented the impact relationships of meteorological, topographical, and environmental data, as well as the dryness index based on satellite images and anthropogenic factors, on forest fire occurrence. Additionally, we have demonstrated the potential uses of surface condition data.

Based on the bubble dynamics, the generation and separation of bubble plays a leading role in the heat transfer of boiling condition. Before the bubble separation, micro liquid layer below bubbles is evaporated to dryness and heat transfer deterioration is the ultimate cause of boiling crisis, proposed a critical heat flux mechanism in the conditions of low velocity and narrow channel. A critical heat flux mechanism model is established. By calculation, in the low mass flow range the mechanism model has a high precision to predict CHF in a larger pressure and export dry degree ranges. Using the model the relationship of parameters is studied.

Nowadays, climate change and heat extremes are becoming highly challenging problems in many cities across the globe. One of the solutions to overcome this problem is the use of vegetation, and, in particular, extending the range of overgrown areas, which are sometimes referred to as “urban green areas.” In this paper, the moisture condition and its mitigating effect on Land Surface Temperature in urban areas were examined in Warsaw, Poland, using satellite data. To do so, the so-called “Triangle Method” was employed. The triangle method is based on a Land Surface Temperature–Normalized Difference Vegetation Index (LST-NDVI) scatterplot to calculate the Temperature Vegetation Dryness Index (TVDI) and its modification–quadratic Temperature Vegetation Dryness Index (qTVDI). This article discusses, in detail, the usefulness of the triangle method for the analyses of built-up areas. The drought satellite indices TVDI and qTVDI compared with those of LST, NDVI, and NDBI (Normalized Difference Building Index). The study shows that the triangle method based on LST-NDVI scatterplot analysis is a promising tool for establishing moisture conditions over urban areas and for studying the effect of vegetation impact on urban heat islands. Detailed analysis shows that over an urban area, qTVDI shows better agreement with LST than classic TVDI.

The value of plant soil resistance is related to the water content in the soil under conditions of sufficient or water drought. When the water content in the plant's soil decreases, it can cause the plant to wither. In this study, the soil water conditions of the plants were tested in sufficient condition or experiencing drought based on the soil resistance value of the plant. The test results on plant soil are in a rectangular container having the dimensions of the parameters of length, width and height in centimeters. The results of the research on plant soils were in the container in the condition that the soil water content was sufficient, the soil resistance value R(t.c) = 40.5 kOhm. The condition of the plant soil experienced water drought, the value of soil resistance parameter R(t.k) = 51.2 kOhm. An indication of the water content of the plant's soil experiencing water dryness, the electronic switch from the electronic circuit equipment activates a buzzer sound. Then watering is carried out into the soil container of the plants experiencing water drought to prevent the plants from wilting, then the electronic switch deactivates the buzzer condition so that it does not sound.

ABSTRACT Well-defined erythematous plaques with silvery-white scales are the hallmarks of the chronic, noninfectious inflammatory skin disorder known as psoriasis. Due to recurrence, it has remained a serious problem. There is no treatment for this condition. The Ayurvedic diagnosis is Ekakushtha, which is a Vata-Kappa-predominant Kshudrakushtha. A 30-year-old female patient visited Ocean Healing Centre in Karnal, India, with complaints of Keshbhoomi rukshata (dryness of scalp), flanks/scales over the back, head, hands, and legs, and itching over the past 3 years. She has taken steroidal medication, but there has been no improvement. Kutaja Kwatha (Wrightia tinctoria), 40 mL BD, was used to treat the ailment before meal internally and Bruhath Dantphladi taila (W. tinctoria) for external application five times a day. The patient was advised to take a capsule of Mahatikta Ghrita once a day after treatment for 1 month. In Avara Satva or Avara Bala patients, Shodhan is contraindicated, in that condition, this Shamana chikitsa is very beneficial and easy to follow. As Kutaja is tikta rasa pradhan and having Rakta dhatu Shodhan property, that’s why Kutaja is used externally and internally in this study and Mahatikta Ghrita prevents dryness of skin as well as prevent relapsing of symptoms. The treatment protocol was found effective in the restoration of normal skin and prevention of recurrence of psoriasis.

Eczema is a chronic inflammatory skin disease, clinically and histologically very similar to contact dermatitis. Eczema offers a wide clinical spectrum ranging from minor forms presented by a few dry eczematous patches to major forms with an erythematous rash. Vicharchika has been described in Ayurveda texts. It is characterized by symptoms, namely kandu (itching), strava (discharge), pidika (vesicles), rukshata (dryness) and shyava varna (discolouration). This condition has two forms, one of which is ruksha or dry form, and the other is the sravi or the moist form, based on its clinical presentation. The clinical features of ruksha Vicharchika simulate the typical clinical manifestation of dry eczema. In the present case study, a 64-year-old male complained of scaly lesions over both palms, the dorsum of both feet and the anterior aspect of the lower leg associated with severe itching and dryness for eight months. The Ayurvedic diagnosis was made as Vicharchika (dry eczema) based on signs and symptoms. The patient was treated with Ayurvedic formulations, i.e. Chandrashakaladi vati and Arka taila, and the treatment continued for one month. The patient’s condition was assessed for signs and symptoms of dry eczema. During the treatment all the signs and symptoms of Vicharchika reduced to a very high extent. This study shows that cases of eczema can be successfully managed with ayurvedic treatment only without any complications and side effects.

Sensitive skin is a common condition, affecting about half of the general population. This condition is characterized by a number of unpleasant skin symptoms (tingling, burning, pain, and itching) that occur in response to triggers that usually do not cause such reactions. Severe dryness of the skin is often observed in patients with sensitive skin. Nowadays, treatment of the condition of sensitive dry skin comes down to the use of moisturizing care products. We conducted a study of the clinical effectiveness of moisturizing products, which included 50 volunteers. According to the study data, a signifcant effect was achieved by the 21st day of using moisturizers. However, long-term use for more than 2 months allowed to maintain normal values of corneometric parameters even after cancelation moisturizers.

Abstract Atopic dermatitis (AD) is a skin inflammatory disease, characterized by itch, redness, swelling, oozing, thickening or dryness of skin. The condition typically starts from infancy with changing clinical severity in adolescence and adulthood. It bothers not only the health but also quality of life. The interactions between skin microbes and the skin conditions have been implicated in atopic dermatitis. However, the interplay between host immunity, gut and oral microbiota and clinical features in children remains unclear. In this study, we recruited 30 subjects (17 boys and 13 girls) with atopic dermatitis in a medical center in Taiwan. The mean age was 7.11±5.20 years old. The presentation of skin lesions included redness (73.3%), itch (66.7%), dryness (56.7%) and oozing (36.7%). Some of the patients have comorbidities of allergic rhinitis (30%) and asthma (10%). The mean SCORAD index was 55.33±16.96, with an involvement of 52.58±19.35% of body surface area. The mean eosinophil count was 12.01% and the total IgE was 5040.17 IU/mL. The gut and oral microbiomes were analyzed by using 16S rRNA gene and metagenome sequence analyses. Sterptococcal species are the major oral species and Bacteroides species are the major gut species associated with AD in children. Our data suggest that oral and gut microbiota may underlie the clinical features of AD. Further investigations on the interplay of microbiota, immunity and clinical features are warranted.

Recently, an article published in this journal by Dr Seifaddini and colleagues. In that article, the authors tried to connect dementia, including Alzheimer’s disease, with a condition mentioned in Iranian traditional medical condition, Raoonat and Homgh. In this condition, intellectual functions of the brain are disturbed and therefore, learning and decision-making abilities are damaged. This condition is not age limited and affects thinking ability but not memory. On the other hand, there is a condition described in Iranian traditional medicine, which completely matches with Alzheimer’s disease. This condition is explained under the title of Nesyan (forgetfulness). Nesyan has 5 subdivisions, one of which is caused by the inclination of the brain normal temperament to more coldness and dryness. By performing animal studies, we have recently shown that this kind of Nesyan is related with Alzheimer’s disease. Studies on the traditional recommendations on treatment of this kind of Nesyan can be useful in treatment of Alzheimer’s disease.

Various drought indices have been developed to monitor drought conditions. Each index has typical characteristics that make it applicable to a specific environment. In this study, six popular drought indices, namely, precipitation condition index (PCI), temperature condition index (TCI), vegetation condition index (VCI), vegetation health index (VHI), scaled drought condition index (SDCI), and temperature–vegetation dryness index (TVDI), have been used to monitor droughts in the Greater Changbai Mountains(GCM) in recent years. The spatial pattern and temporal trend of droughts in this area in the period 2001–2018 were explored by calculating these indices from multi-source remote sensing data. Significant spatial–temporal variations were identified. The results of a slope analysis along with the F-statistic test showed that up to 20% of the study area showed a significant increasing or decreasing trend in drought. It was found that some drought indices cannot be explained by meteorological observations because of the time lag between meteorological drought and vegetation response. The drought condition and its changing pattern differ from various land cover types and indices, but the relative drought situation of different landforms is consistent among all indices. This work provides a basic reference for reasonably choosing drought indices for monitoring drought in the GCM to gain a better understanding of the ecosystem conditions and environment.

Abstract Maros Regency is one of the rice storage areas in South Sulawesi. According to the Central Bureau of Statistics for Maros Regency in 2020, the harvested area of rice decreased by 10.11% or 4,849.55 Ha compared to 2018 and rice production decreased by 16.96% or 37,719.68 tons. This causes the productivity of rice also decreased. One of the factors causing the decline in rice production in Maros Regency is drought. Sentinel 2 imagery is one of the remote sensing data that can be used to detect rice drought using the drought index method. This study aims to detect dryness of paddy rice in Allatengae Village using Sentinel-2A satellite imagery based on NDDI index analysis and determine the relationship between drought index and rice productivity. The method used is the Normalized Difference Drought Index (NDDI) method to determine the dryness level of paddy fields based on NDVI and NDWI parameters and uses regression and correlation analysis methods. From the results of this study, dry rice in Allatengae Village was detected in September and October 2021. In September (42 HST), the average NDDI value was 0.0254 and was in a mild drought condition while in October (62 HST), the average NDDI value is 0.2425 and is in moderate class drought conditions. From the results of the analysis of the relationship between the drought index and rice productivity, there is a strong (negative) correlation, where the higher the NDDI index value, the lower the rice productivity value.

Xerostomia can be defined as a feeling of dryness of mouth, which may or may not be accompanied with reduced salivary secretions. Xerostomia may result in localized and systemic disturbances within the body. The overall global prevalence of xerostomia is 22% with wide variation among different countries due to difference in target population. This review presents the recent literature on the diagnostic methodologies that are present in recent times through subjective and objective corridors. The most commonly used subjective methods for the xerostomia diagnosis include: Fox questionnaire, Visual Analogue Scale (VAS), Xerostomia Inventory (XI), and Shortened Xerostomia Inventory (SXI). Objective xerostomia diagnostic tools include salivary flow rate assessment. Aside from this, there are numerous radiographical modalities that can be used especially in diagnosing salivary gland disorders or radiation exposure due to oncological treatments which can also provide the added information to diagnose or monitor xerostomia. These radiographic tools include computer tomography (CT), scintigraphy, sialography, magnetic resonance imaging (MRI), and ultrasonography. Different combination of tools gives a better xerostomia assessment, selection of which also depends on the age and health condition of the patient.

Eyes’ dryness continues to be the most frequent complication after LASIK. As a rule, it disappear in the vast majority of patients during the first year after surgery. The conducted studies indicate that complaints of eyes’ dryness in the preoperative period significantly increase the risk of developing a severe form of dry eye syndrome in the postoperative period, especially in middle-aged women (45–59 years) and older. The clinical case presented in this article indicates the development of a severe form of dry eye syndrome after LASIK in a middle-aged patient receiving hormone replacement therapy for menopause, complaining of a feeling of dryness and discomfort in the eyes in the preoperative period, with intolerance to contact lenses and taking antidepressants in the absence of signs of severe dry eye in the preoperative period. Consequently, surgical intervention led to the development of the mentioned above condition. It is confirmed by the literature data indicating that the above factors can cause the development of a severe form of dry eye syndrome after LASIK. Taking into account the fact that tear production tests do not always correlate with the intensity of complaints of dryness, burning sensation, pain in the eyes, the most important component at the stage of deciding on the feasibility of refractive surgery in a particular patient is the collection of anamnesis and clinical picture. When preparing patients with a history of dry eye syndrome for refractive surgery, it is necessary to inform them that they have a significantly increased risk of developing dry eye syndrome. It may persist in the long-term postoperative period, and possibly go into a chronic form. Candidates for refractive surgery in the presence of complaints characteristic of dry eye syndrome can only be those patients who respond well to therapy aimed at relieving these symptoms in the preoperative period. Taking into account the multicomponent nature of pain in dry eye syndrome — nociceptive pain, which is formed at the stage of receptor irritation in the corneal tissue, and neuropathic pain that occurs with the participation of the peripheral and central nervous system, a comprehensive approach is needed in the treatment of dry eye syndrome.

Vulvar and vaginal atrophy (VVA) is a chronic and progressive medical condition common in postmenopausal women. Symptoms of VVA such as dyspareunia, vaginal dryness, irritation, and itching can negatively impact sexual function and quality of life. The REVIVE (REal Women's Views of Treatment Options for Menopausal Vaginal ChangEs) survey assessed knowledge about VVA and recorded attitudes about interactions with healthcare providers (HCPs) and available treatment options for VVA. The REVIVE survey identified unmet needs of women with VVA symptoms such as poor understanding of the condition, poor communication with HCPs despite the presence of vaginal symptoms, and concerns about the safety, convenience, and efficacy of available VVA treatments. HCPs can address these unmet needs by proactively identifying patients with VVA and educating them about the condition as well as discussing treatment preferences and available therapies for VVA.

Indonesia National Board for Disaster Management (BNPB) said that in 2002-2009 the drought was the second most frequent intensity after the flood disaster. Drought is a condition where a region experiences a lack of water. If this drought occurs in the agricultural area, it will certainly affect the plants that grow. One of the potential detection methods for drought can be using remote sensing. Temperature Vegetation Dryness Index (TVDI) is one method to detect drought potential with two parameters, vegetation index, and temperature. Through the triangle method, there is a relationship between the vegetation index and temperature represented by linear equations. These linear equations are used to calculate TVDI values. This study uses data Landsat 8 image and paddy fields. The objective of this research is how the distribution and the area of drought based on the TVDI algorithm. The TVDI with dry classes diffuse in the central and western parts, it is also the TVDI with the largest area about 155.82 km2 or 44% of the total. TVDI with wet classes can be seen in the western part of the region and the smallest area about 32.94 km2 or 9% of the total.

Material and Methods. A total of 64 patients with complaints of oral dryness referred to the Clinic of Oral and Dental Diseases, Hospital of Lithuanian University of Health Sciences, for consultation during the period from 2003 to 2005 were selected for the study. The etiological factors of xerostomia were as follows: radiotherapy (PRT) to the maxillofacial area, Sjögren’s syndrome (SS), and xerogenic medications, tricyclic antidepressants (TCAs). Results. There were 50 women and 14 men. Their mean age was 60.5±1.6 years. All the patients in the PRT group had high counts of Candida spp. as compared with percentages of patients in the TCA and SS groups (100% vs. 66.7% and 56.2%, P<0.05). Patients’ age and sex in different etiology groups had no significant impact on the condition of their oral microflora. There were equal percentages of patients with deficient and normal salivation in the TCA group (44% in both the groups; P<0.01). All the patients in the PRT group had pronounced hyposalivation (P<0.002). A significantly greater percentage of patients with severely reduced salivation had high counts of Lactobacillus spp. (P<0.01). Significantly greater percentages of patients with the clinical duration of xerostomia of up to 6 months had high counts of Lactobacillus spp. and Candida spp. colonies. Conclusions. In patients with xerostomia, the condition of the microflora of the oral cavity and impairment of major salivary gland function varied according to the etiology of the disease. The level of hyposalivation and the duration of xerostomia were found to have a significant impact on the microflora of the oral cavity.

Background and Objectives: Postmenopausal vaginal discomfort is often attributed to vulvovaginal atrophy (VVA). Women with VVA experience symptoms such as vaginal dryness, itching, burning, irritation, and dyspareunia. Materials and Methods: This pilot study was conducted to assess the effects of a micro-ablative fractional CO2 laser on the clinical symptoms of VVA, as well as concordant sexual function. The severity of VVA symptoms was evaluated by a visual analogue scale (VAS), while the condition of the vaginal mucosa was evaluated using the Vaginal Health Index Score (VHSI). Sexual function was evaluated using the Female Sexual Function Index (FSFI) Questionnaire. Results: Our cohort included 84 sexually active postmenopausal women with bothersome VVA, leading to sexual health complaints. The mean age of the participants in our study was 55.2 ± 5.4 years, with an average postmenopausal period of 6 ± 4.8 years. The age of our patients and the length of their postmenopausal period exhibited a significant negative correlation with VHSI scores, while a longer postmenopausal period was associated with increased severity of vaginal dryness and dyspareunia. Baseline VHSI values showed that 65% of patients had atrophic vaginitis with pronounced VVA symptoms (70.2% experienced vaginal itching, 73.8% reported vaginal burning, 95.3% had vaginal dryness, and 86.1% suffered from dyspareunia). Lower VHSI values significantly correlated with lower FSFI scores, while more severe VVA symptoms scores correlated with lower FSFI scores. VVA symptoms were significantly less severe after treatment. VHIS regained high non-atrophic values in 98.8% of patients post-treatment (p < 0.001). FSFI total and domain scores were significantly higher after treatment (p < 0.001). Conclusions: Our study revealed that fractional CO2 laser is a useful treatment option to alleviate VVA symptoms and improve vaginal health and sexual functioning in postmenopausal women.

Abstract Introduction: Atopic dermatitis is an inflammatory skin condition that begins in infancy, characterized by extreme skin dryness, excoriations, and erythema. A completely natural product with plant extracts and vegetable oils was developed to manage eczema and associated conditions in a mixed population including infants. Materials and Methods: An open-label, single-arm, single-center study was conducted to evaluate the safety and efficacy of the test product on eczema severity. A total of 58 subjects, including infants, children, and adults aged 0 months to 60 years, diagnosed with mild-to-moderate eczema, were included. The subjects applied a small amount of product on the affected area twice daily for 14 days. Three-Item Severity (TIS) score, Eczema Area and Severity Index (EASI) change, and symptomatic relief were assessed at various time points. Results: The TIS score in children significantly reduced from baseline at 24 h (12.22%), day 7 (52.26%), and day 14 (79.74%), (all P <0.0001). Similarly, a statistically significant reduction in EASI was observed in adults at day 7 (13.68%) and day 14 (30.87%) (all P < 0.0001), which continued to offer relief throughout the study duration. Irritation significantly decreased from baseline throughout the study duration to day 14 (75.17%) (P < 0.0001). A significant reduction in other symptoms including dryness, itching, rashes, and edema was also seen from day 7 to day 14 (P < 0.0001). Conclusion: The test product was found to be safe and effective in reducing eczema severity and associated conditions in infants and adults. It promotes the development of healthy neonatal skin and hence can be considered as a skin-healing cream for infants.

Su-al-Qinniya (Anemia) is a condition where there is a decrease in blood volume and alterations in its components, accompanied by a reduction in the number of Kurriyat-e-Hamrah (Red Blood Cells). This condition can arise from various factors, including inadequate dietary intake, low socioeconomic status, persistent illnesses, poor iron absorption, ongoing blood loss, and conditions such as bleeding peptic ulcers, inflammatory bowel disease, hookworm infestation, hemorrhoids, and heavy menstrual bleeding. Specific health situations like pregnancy and rapid growth can also trigger Iron Deficiency Anemia (IDA). In Unani literature, anemia has been described by various names such as Faqr al dam, Sū’-al-Qinniya, Qillatuddam, Kamie khoon, and Fasad’ al dam. The abnormal cold temperament of the liver is attributed to dryness and decreased blood, leading to paleness of the body. Anemia may also develop when the liver becomes functionally weak, causing alterations in temperament. This review paper outlines the etiopathogenesis, clinical presentation, various regimens, and herbal formulations used in the management of Su-al-Qinniya (Anemia).

Objective — to evaluate some qualitative and quantitative parameters of mixed saliva in patients at risk of metabolic‑associated diseases and military personnel under the conditions of the armed conflict in Ukraine.
Materials and methods. The study involved patients who were included in three groups: the main group (27 individuals at risk of metabolic diseases), comparison group (19 military personnel) and control group (10 somatically healthy individuals). The survey has been performed with the use of questionnaire to assess dryness in the oral cavity, issues of changes in oral hygiene during the last year. To investigate some qualitative and quantitative parameters of unstimulated saliva, fasting oral fluid was collected in the morning. Salivation rate, oral fluid viscosity, and type of microcrystallization were studied using standard techniques.
Results. Prevalence of persons, in whom the nature of nutrition and individual care of the oral cavity had changed, was established in all investigated groups. The study of the salivation rate revealed a significant decrease in salivation in patients of the main group and comparison groups vs the control group. The lowest secretion level was defined in patients with a risk of metabolic‑associated diseases, whose oral fluid viscosity had the highest values. The most favorable type I of crystallization prevailed only in patients of the control group, it was rare in the main group, whereas in the group of military personnel it was not found, and type II was defined in 26.3% of subjects. Negative changes in the normal life against the background of hostilities resulted in the deterioration in the physical indicators of salivation in both main and comparison groups.
Conclusions. Long‑term chronic stress causes changes in the qualitative and quantitative composition of oral fluid. The study of microcrystallization of the mixed saliva can be used as a non‑invasive diagnostic method for detecting stress as one of the risk factors for premature aging in patients at risk of metabolic‑associated diseases.

The pyrolysis of bamboo waste has been investigated. The effects of carbonization temperature, heating rate and carbonization time on characters of biomass carbonization was investigated by the orthogonal design. The optimized operating condition of bamboo waste was achieved by the analysis of variance: the carbonization temperature is 400 °C, the heating rate is 10 °C /min, the carbonization time is 60min.The yield of bamboo waste under the optimized operating conditions is 31.8%, and ash is 3.9%. The thermogravimetric analysis of the bamboo waste was carried out in a thermogravimetric analyzer. The analysis of TG and DSC curves indicates that the pyrolysis of bamboo waste should be divided into four steps: the dryness is below120 °C, from 120 to 240°C is preheating section, and pyrolysis occurs at 230 to 370 °C and after 370 °C is carbonization process.

Xerostomia is a condition that develops with a decrease in saliva secretion (hyposialia) or cessation of saliva secretion (asialia) and is characterized by dryness in the oral cavity. Xerostomia is widespread in different age groups, but is most common in older age groups. In a number of diseases, for example, in Sjogren's disease, xerostomia is the leading symptom complex and determines the severity of the clinical picture. Chronic inflammatory diseases of the pharynx, such as chronic tonsillitis and chronic pharyngitis, may be accompanied by a pronounced decrease in saliva secretion. Timely conservative treatment of inflammatory diseases of the pharynx has a positive effect on the dynamics of the course of xerostomia. To diagnose this condition, patients are advised to undergo sialometry. Xerostomia can be observed in the long term after bilateral tonsillectomy and, which forces patients to seek medical help. To eliminate dryness in the oral cavity after otorhinolaryngological interventions, in particular after bilateral tonsillectomy, saliva substitutes are widely used in practical otorhinolaryngology. Data on the relationship between the state of the lymphoid-pharyngeal ring and xerostomia syndrome are presented in the modern literature by single publications, and therefore, studies of the relationship between inflammatory diseases of the pharynx and the level of saliva secretion are certainly of significant scientific and practical interest. Treatment of patients suffering from both subjective and objective xerostomia requires an interdisciplinary approach with the participation of a dentist, otorhinolaryngologist and doctors of other specialties (gerantologist, endocrinologist, rheumatologist, psychotherapist). Modern methods of surgical treatment of patients with chronic tonsillitis and xerostomia using radio wave methods, highenergy laser radiation, coblator should be considered as an alternative to classical bilateral tonsillectomy.

Urogenital atrophy, although a frequently occurring symptom of aging for all women, is a condition often not thought of as a symptom of distress for older women or a sign of pelvic pathology requiring treatment by clinicians. Rather, many clinicians feel it is an expected consequence of aging, and older women themselves assimilate their lifestyle to the uncomfortable symptoms of dryness, irritation, itching and malodorous discharge. At times, when symptoms become intolerable with coitus, women will abandon sexual intercourse with their partners due to dyspareunia and not seek intervention to reverse the condition owing to embarrassment in raising this sensitive topic. When urogenital atrophy is diagnosed and the patient requests treatment, the gold standard intervention is estrogen, which can either be delivered systemically or vaginally. Since the Women's Health Initiative data, low-dose, vaginally delivered estrogen is recommended.
