Abstract It is of paramount concern that some leather tanneries around the world are disposing waste in environment which are a cause of destruction of flora and fauna in vicinity. Especially chrome tanning poses a major threat due to the release of chromium in wastewater (WW). Hexavalent chromium (Cr6+) is a potential carcinogen and thus demands stern quality control measures. The present investigations focused on the quality of WW released from leather tanneries of two cities i.e., Sheihupura and Kasur, Pakistan, and its effect on the vicinal flora. Cr6+ and total chromium (Cr) in all the samples were determined through UV visible spectroscopy and atomic absorption spectroscopy (AAS). Wastewater samples (WWS) were collected at head and at a distance of 50 – 200 m at specific intervals, at edge and inward towards middle of WW streams. WWS of both Sheihupura and Kasur tanneries showed comparable Cr6+ content at head but much higher total Cr (in parenthesis) in later i.e., 89.7 ppm (1440.57 ppm) and 94.9 ppm (3527.95 ppm). Cr6+ content declined inward stream and with the increasing distance down the stream falling exponentially in Sheikupura and steeply at Kasur. The soil samples (SS) at 3 m i.e., at edge of WW streams showed higher Cr6+ content for Sheikhupura than WWS i.e., 94.8 ppm (1041.8 ppm) falling with distance to 44.8 ppm at 150 m. It is less at Kasur i.e., 80.5 ppm (4465.9 ppm) falling sharply with distance at 150 m to 25.1 ppm. This showed buildup of Cr6+ ions in soil of Sheikupura with time. As the distance off stream on the ground increased, both Cr6+ and the total Cr declined and much more at Kasur site i.e., 23.8 ppm (880 ppm) and reached close to Sheikhupura 32.7 ppm (610 ppm) at 150 m. Plausibly, the Sheikhupura tannery is older and/or the soil in vicinal area is more porous. Plant vegetation examined in soil at edge only, show the uptake of both Cr6+ and total Cr. Roots and grass leaf at Sheikhupura and the potato leaf at Kasur showed the highest Cr6+ uptake of the total Cr i.e., 4.6% 3.5% and 6.4 %, respectively. The results show that tanneries WW has drastically affected soil and consequently the plants with Cr6+ ions and total Cr above the permissible levels of 0.1 ppm. To ratiocinate, these will finally incorporate in food chain ultimately damaging the fauna and henceforth calls for adoption of effective removal methodologies and greener routes for a sustainable environment.

Cerebrovascular diseases are a problem of the world today, and according to the forecast, the problem of the near future arises. The main risk factors for the development of ischemic disorders of the cerebral circulation include oblique and aging, arterial hypertension, smoking, diabetes mellitus and heart disease. An effective strategy for the prevention of cerebrovascular events is based on the implementation of large-scale risk control measures, including the use of antiagregant and anticoagulant therapy, invasive interventions such as atheromectomy, angioplasty and stenting. In this connection, the efforts of neurologists, cardiologists, angiosurgery, endocrinologists and other specialists are the basis for achieving an acceptable clinical outcome. A review of the SF-36 method for assessing the quality of life in patients with the effects of transient ischemic stroke is presented. The assessment of quality of life is recognized in world medical practice and research, an indicator that is also used to assess the quality of the health system and in general sociological research.

Viral diseases in viticulture lead to annual losses in the quantity and quality of grape production. Since no direct control measures are available in practice, preventive measures are taken to keep the vines healthy. These include, for example, the testing of propagation material for viruses such as Arabis mosaic virus (ArMV), Grapevine fanleaf virus (GFLV) or Grapevine leafroll-associated virus 1 (GLRaV-1) and 3 (GLRaV-3). As long-term investigations have shown, GLRaV-1 (2.1%) occurs most frequently in southwestern German wine-growing regions, whereas GLRaV-3 (<0.1%) is almost never found. However, tests conducted over 12 years indicate that there is no general decline in virus-infected planting material. Thus, it can be assumed that a spread of the viruses via corresponding vectors still takes place unhindered. Beyond the examinations regulated within the German Wine Growing Ordinance, one-time tests were carried out on Grapevine Pinot gris virus (GPGV). This analysis showed that GPGV was found in 17.2% of the samples.

The study aimed to evaluate the effects of process parameters (time and raw material weight (RMW)) of conventional (boiling for 10–45 min) and microwave-assisted (2–8 min) aqueous extraction on the color quality (i.e., lightness (L*), chroma (C*), and hue (H°) of anthocyanin –based colorants of red and Inubi sweet potato (Ipomoea batatas L.) leaves. Using response surface methodology, it was found that RMW and boiling time (BT) and microwave time (MT) generally had a significant (p < 0.05) effect on the color quality of the extract from both extraction methods. The effects were found to vary depending on the extraction method and variety of the leaves used. Both extraction methods produced a brown to brick-red extract from the Inubi variety that turned red-violet to pink when acidified. The red sweet potato leaves produced a deep violet colored extract that also turned red-violet when acidified. It is recommended that the anthocyanin content of the extracts be measured to validate the impact of the methods on the active agent. Nevertheless, the outcomes in this study may serve as baseline data for further studies on the potential of sweet potato leaf colorants (SPLC) as a colorant with functional properties.

Abstract Nursing home facilities are responsible for providing care for some of the most vulnerable groups in society, including the elderly and those with chronic medical conditions. In times of crisis, such as COVID-19 or other pandemics, the delivery of ‘regular’ care can be significantly impacted. In relation to COVID-19, there is an insufficient supply of personal protective equipment (PPE) to care for residents, as PPE not only protects care staff but also residents. Nursing homes across the United States and Canada have also taken protective measures to maximize the safety of residents by banning visitors, stopping all group activities, and increasing infection control measures. This presentation shares a research protocol and early findings from a study investigating the impact of COVID-19 on quality of care in residential long-term care (LTC) in the Canadian province of New Brunswick. This study used a qualitative description design to explore what contributes to quality of care for residents living in long-term care, and how this could change in times of crisis from the perspective of long-term care staff. Interviews were conducted with a broad range of staff at one LTC home. A semi-structured interview guide and approach to thematic analysis was framed by a social ecological perspective, making it possible to include the individual and proximal social influences as well as community, organizations, and policy influencers. Insights gained will improve the understanding of quality of care, as well as potential barriers and facilitators to care during times of crisis.

We examined the role of chromium reduction in the Golgi-Colonnier method, correlating the quality of neuronal impregnation with the levels of hexavalent (CrVI) and trivalent (CrIII) chromium in the tissue and in the chromation fluid (CF). The concentrations of both chromium species were assessed by measuring spectrophotometrically the CrVI before and after oxidizing the sample and by calculating the ratio of CrVI to total chromium (chromium ratio, CrR). The CrR was almost identical in the tissue and the CF, decreasing exponentially during chromation due to a progressive consumption of CrVI to form CrIII. Satisfactory cell impregnation was obtained only when the CrR was 0.45-0.7, regardless of other factors. The CrR values could be accurately predicted by the pH increase of the CF; this increase has proven to be a most reliable criterion to decide the endpoint of the chromation process. The dependence of cell staining on the [CrIII], together with the well-known ability of this species to bridge proteins, suggests that the key event for cell impregnation is the cross-linking of neuronal proteins by CrIII polymers.

Yield and quality of herbage seed can be affected by many diseases. In New Zealand the most important diseases of grasses are rusts, especially stem rust on ryegrasses, cocksfoot and timothy; head smut of bromes; and ergot of paspalum. Blind-seed disease is of minor importance on ryegrass at present. Clover yield can be affected by rot, scorch and stem nematode. These diseases and others are discussed in relation to changing farming practices, and disease control measures are suggested.

ABSTRACT Standards and regulations related to spirit drinks have been established by different countries and international organizations to ensure the safety and quality of spirits. Here, we introduce the principles of food safety and quality standards for alcoholic beverages and then compare the key indicators used in the distinct standards of the Codex Alimentarius Commission, the European Union, the People's Republic of China, the United States, Canada, and Australia. We also discuss in detail the “maximum level” of the following main contaminants of spirit drinks: methanol, higher alcohols, ethyl carbamate, hydrocyanic acid, heavy metals, mycotoxins, phthalates, and aldehydes. Furthermore, the control measures used for potential hazards are introduced. Harmonization of the current requirements based on comprehensive scope analysis and the risk assessment approach will enhance both the trade and quality of distilled spirits. This review article provides valuable information that will enable producers, traders, governments, and researchers to increase their knowledge of spirit drink safety requirements, control measures, and research trends.

Rain-induced cracking of sweet cherries (Prunus avium L.) is a major problem in many cherry growing regions throughout the world. One method to reduce cracking is to grow cracking resistant cultivars; however, no completely effective control measures are currently available to eliminate this problem. Studies conducted in New Zealand to test the ameliorating properties of gibberellic acid sprays to reduce cracking were examined. The results revealed that repeated or singular foliar applications at 10 or 40 mg L-1 gibberellic acid (GA3), respectively, increased both fruit cracking, and fruit firmness, but delayed fruit colour development. Key words: Prunus avium, cherry splitting, cracking

The concept of Sustainable development underlines the long lasting development of an economy by an efficient resource use fulfilling the economic, social and environmental aspects together. The SDGs by the UNDP focus  on 17 goals for all countries to end poverty, protect the planet and ensure that all people enjoy peace and prosperity.The mission of Smart Cities in India is to promote cities that provide core infrastructure and give a decent quality of life to its citizens, a clean and sustainable environment and application of ‘Smart’ Solutions. The focus is on sustainable and inclusive development of the Mega cities, an indispensable outcome of the development process and urbanization implied in it. During the course of economic development over last 70 years in India, many cities have emerged as unsustainable and highly vulnerable to manmade calamities.This paper would elaborate on the details of Smart city project in India in the light of Sustainable development. The Smart cities mission though aims at sustainable development, this path is full of challenges along with some opportunities in disguise. The paper would suggest some policy implications such as developing smart villages along with these smart cities to bridge the gap between the rural and urban India.   Keywords: Smart city mission, Sustainable development, Smart villages, Sustainable Development Goals (SDGs)
