In 2002 the USDA reported potted geraniums accounted for $150 million in wholesale value, more than any other bedding or garden plant surveyed. Despite the importance of the geranium in floriculture production, little published research data is available pertaining to the media pH requirements of zonal and ivy geraniums. Current recommendations suggest zonal geraniums be grown at pH 5.7-6.6 and ivy geraniums at pH 5.0-6.2. The wide range in root medium pH recommendations for both zonal and ivy geraniums and the lack of research data prompted this research. Also, the basis for recommending a lower medium pH for ivy geraniums could not be found in published literature. The research objectives were to investigate the effect of medium pH on plant growth and to determine more precise recommendations for both species. The growth of 3 cultivars each of zonal and ivy geraniums growing in 8 medium pH treatments were evaluated. Limestone and hydrated lime were incorporated at increasing rates into a 1:1:1 peat, perlite and bark mix to achieve a medium pH ranging from pH 4.0-7.5. Plants were harvested at weeks 3, 6, and 11 and plant dry weight and media pH were determined. Leaf luminance, chroma and hue were evaluated at week 10. Plant dry weight was greatest at pH 6.55 or higher for both zonal and ivy geraniums at week 11. Leaves of plants grown at pH 6.55 or higher had significantly lower luminance and chroma and greater hue in all cultivars, corresponding to leaves that were darker, less vivid, and deeper green in color. This study shows a root medium pH greater than pH 6.5 results in greatest plant dry weight accumulation and quality of leaf color for both zonal and ivy geraniums. This study also shows ivy geraniums can be grown at the same media pH as zonal geraniums.

Three cultivars each of zonal geranium (Pelargonium ×hortorum `Candy Lavender', `Fireball', and `Patriot Red') and ivy geraniums (Pelargonium pelatum `Global Deep Lilac', `Global Salmon Rose', and `Global Soft Pink') were grown in root media with pHs varying from 4.3 to 7.8. In Expt. 1, a mixture of sphagnum peat, fine perlite, and fine pine bark was modified with limestone and hydrated lime at the following rates: 0, 1.2, 3.0, 4.7, and 11.9 kg·m–3 limestone; 11.9 limestone plus 5.9 hydrated lime; 11.9 limestone plus 8.3 hydrated lime; and 11.9 kg·m–3 limestone plus 10.7 kg·m–3 hydrated lime to give the various root medium pH treatments. Plants were grown for 11 weeks in glass greenhouses. In Expt. 2, plants were grown in two commercial soilless mixes with one being modified with the addition of 0 kg·m–3 limestone, 6.0 kg·m–3 limestone plus 0.6 kg·m–3 hydrated lime, and 6.0 kg·m–3 limestone plus 2.4 kg·m–3 hydrated lime. In both experiments, greatest dry weight was recorded in zonal and ivy geraniums plants grown at root medium pHs above 6.4. This study showed a root medium pH of 6.4 to 6.5 should be recommended for the greenhouse production of both zonal and ivy geraniums.

To evaluate the quantity and quality of the use of statistics in Austrian medical journals, all “original research” papers in No. 116/1-12 of Wiener Klinische Wochenschrift (WKW) and 153/1-24, 154/1-24 of Wiener Medizinische Wochenschrift(WMW) were screened for their statistical content. Types, frequencies and complexity of statistical methods applied weresystematically recorded. A 46-item checklist was used to evaluate statistical quality for a subgroup of papers. 74.3% of WKW papers contained inferential methods beyond descriptive statistics. Only 43.7% of WMW papers employed methods of inferential statistics. There was a statistical significant difference regarding the use of statistical methods between the two journals (p = 0:009). In addition, complexity and sophistication of statistical analysis was considerable higher for WKW papers (p = 0:02). Statistical errorsand deficiencies were identified in a large proportion of papers. Although inferential statistics were frequently identified in papers from WKW, only a minority of WMW research had analytical character. Types and frequencies of statistical errors identified, did not vary meaningful from findings of similar studies for a wide range of medical journals. There is reason to assume, that the journal impact-factor does not seem to be a powerful predictor for the statistical quality of published research.

Hybrid impatiens (Impatiens wallerana Hook. F.) were planted into media containing two dolomitic liming materials {hydrated [Ca(OH)2 and Mg(OH)2] or carbonate (CaCO3 and MgCO3) lime} and subirrigated for 17 weeks with four irrigation water sources (IWS) and three water-soluble fertilizers (WSF). The WSF contained 200N–20P–200K mg·L-1 but varied in NH4+-N content (50%, 25%, or 3%, respectively). Depending on the IWS and lime type used in the media, root-medium pH ranged from 4.5 to 6.0, 4.8 to 7.1, and 6.0 to 8.5 when treated with WSF containing either 50%, 25%, or 3% NH4+-N, respectively, between 8 and 17 weeks after planting. The accumulation of NH4+-N and NO3--N in the root medium was different for treatments receiving the same WSF and depended on root-medium pH. The critical root-medium pH for NH4+-N accumulation was between 5.4 and 5.7, and for NO3--N, accumulation was between 5.3 to 5.9. Above this pH, minimal NH4+-N concentrations were measured in the medium, even with 50% or 25% NH4+-N WSF, while below this pH, NH4+-N began to accumulate in the medium with a corresponding decrease in the NO3--N concentration. The NH4-N: NO3-N ratios in the WSF had minimal effect on shoot fresh and dry weights. Tissue N concentration was higher with the higher NH4-N : NO3-N ratio WSF at all four sampling dates. There was a linear relationship between higher tissue N and lower root-medium pH with the same WSF, possibly due to differences in the ratio of NH4-N: NO3-N actually taken up by the plant.

Substrate pH of soilless media directly affects nutrient availability. Limited information about the effect of substrate pH on growth of begonia species (not cultivated hybrids) was found in the literature. The objective of this study was to evaluate the effect of substrate pH on the growth and quality of six begonia species grown from June to Aug. 2004. The targeted pH ranges (<4.5, 4.5∼5.0, 5.0∼5.5, 5.5∼6.0, 6.0∼6.5, 6.5∼7.0, and over 7.0) of the peat-based substrates were obtained by adding seven different amounts of dolomitic hydrated lime: 0, 1.0, 1.3, 1.6, 2.0, 2.4, and 2.6 kg·m3. Begonia albopicta, B. cucullata var. cucullata, B. echinosepala var. elongatifolia, B. holtonis, B. fuchsioides (red), and B. fuchsioides (pink), were propagated by stem cuttings, and then transplanted into plastic containers. This experiment was a factorial experiment arranged in a randomized complete-block design. The pH was monitored weekly using the pour-through method and adjusted accordingly by adding flowable lime or a mild sulfuric acid solution. The pH values were averaged for each treatment of each species. There were significant differences between species in the inflorescence number and SPAD readings, but no interaction between species and substrate pH was found. Stem length, leaf area, and dry weight of each plant were significantly affected by species and substrate pH. B. albopicta performed best at substrate pH of 5.6 and 6.0, showing no symptoms of phytotoxicity. B. cucullata, above substrate pH 6.0, and B. holtonis at pH 5.0 and 5.6 had the highest vegetative growth and plant quality. Plant mortality was observed for B. cucullata and B. fuchsioides (red) at pH below 4.4 and 5.3, respectively.

Relevance. Tomato considered a significant vegetable crop that plays a prominent role in the field of human health. At present, there are large numbers of tomato cultivars with a wide range of morphological and sensorial characteristics which determine their use. Farmers often use some chemical substances which have similar structure and activity with endogenous plant hormone called (exogenous) as a low-cost alternative to regulate plant growth and increase yield. Thus, the use of Plant Growth Regulators (PGRs) has become an important component of the agro-technical procedures for most cultivated species.Methods. This study aims to evaluate the effect of four growth regulators (Krezacin, Chitosan, Zircon and Energene) on growth, productivity and quality of two Russian tomato varieties (Moriana and Superjol) under delta Volga conditions. Each type applied three times on both cultivars (Soaking tomato seeds before sowing, spraying on plants at vegetative phase, spraying on plants at flowering phase with three replications.Results. The results showed that; combination between Energene and cultivar Moriana enhanced the most of studied characters (Germination – 83.1%, fresh weight of Arial parts – 241.9 g, dry weight – 74.4 g, Number of № flowers/plant – 51.0, № fruits /plant – 35.6, fruit set – 69.8%, plant yield – 2.44 kg, TSS – 5.1°Brix, Content of Ascorbic Acid – 25.6 mg/100 g); Interaction between “Energene x Superjol” gave the maximum value for Plant height (85.6 cm), Fruit weight (72.6 g); while “Krezacin x Moriana” registered the highest fruit dry matter (6.77%) and Acidity (0.53%); Applying Zircon on Cultivar Moriana increased number of leaves/plant (56.8) and nitrate contents (27.6 mg/kg); the maximum LAI (150.1 cm2 ) obtained from interaction between Chitosan and cultivar Superjol whereas, “Chitosan x Moriana” treatment gave the highest level of Carotenoids (4.12%).

When diagnosing bloodstream infection (BI) the culture medium is the basis for growth of microorganisms and obtaining the blood culture. Pancreatic digest from fish meal is the basis of all culture media in Russia. In European countries brain-heart media (BHM) are used for detecting microorganisms in blood. In Russia BHM is not produced. The aim is to work out the formulation and the way of the BHM (broth and agar) preparation in order to improve the efficiency of obtaining blood culture. There were defined the physical and chemical indices and biological parameters of the BHM. The microbiological control of the BHM was carried out by diagnostic study of cardiological patients’ blood. On the basis of the developed technique of the brain-heart extraction (BHE) preparation there was created the liquid and agar BHM (LBHM, BHA). The LBHM was poured into bottles which then were filled with the inert gas. The bottles were closed with rubber stoppers and rolled in metal caps became a closed system. Microbiological qualities of LBHM were tested on 260 blood samples and thioglycollate medium (TGM) and LBHM. Aerobic microorganisms grew in LBHM 2,4 times more often than in TGM. The microaerophilic microbes grew in LBHM 3,2 times more often than in TGM. Anaerobic microbes did not show any growth in TGM, (p<0,001). Monomicrobes hemocultures were obtained in LBHM 13,4 times more often than in glucose broth and 2,3 times more often than in TGM, (p<0,001). Polymicrobes hemocultures were obtained in LBHM more often than in TGM (7,3% and 1,7%, respectively). The quality of brain-heart agar (BHA) was tested on 300 blood samples in 5% blood meat-pepton agar (MPA) and BHA in aerobic and anaerobic conditions for both the media. Aerobic microorganisms grew in BHA 2 times more often than in MPA. The microaerophilic microbes grew in BHA 3,6 times more often than in MPA. In anaerobic condition in BHA aerobic microorganisms grew 2 times more often than in MPA and the microaerophilic microbes grew 2,5 times more often than in MPA, (p<0,001). Anaerobic microbes did not grow in MPA. When diagnosing bloodstream infection the BHM (liquid and agar) are able to create the optimal conditions for the increase of the wide range pathogen growth.

Fourth Experiment

Four experiments were conducted under greenhouse conditions in Oklahoma. Pelleted ‘Genovese’ basil (Ocimum basilicum) seeds were sown in polystyrene flats with six different blends of a peat-lite mix (PL0) and yard waste compost [YWC (this batch designated C0)] in 2012 for the first two experiments. The proportions by volume of PL0:C0 included 100%:0%, 80%:20%, 60%:40%, 40%:60%, 20%:80%, and 0%:100%. Seedling establishment was unaffected consistently, but there was a distinct decline in seedling height and dry weight between 100% PL0 and 80% PL0:20% C0, followed by smaller decreases as the percentage of compost increased in the blends. A third experiment was conducted in 2013 with a different batch of peat-lite (PL1) after the compost had aged 17 months (now designated C1). Treatments were 100% PL1, 80% PL1:20% C1, and 80% PL1:20% C1 mixed with sulfur (S) at 1, 2, or 3 lb/yard3 of blend to acidify the media. The 100% PL1 treatment delayed seedling emergence and suppressed height and dry weight relative to seedlings grown in 80% PL1:20% C1 blends. The PL1 subsequently was found to have been produced in 2010, and the wetting agent had apparently degraded. The aged 2012 compost (C1) was not inhibitory to basil seedling growth when blended at 20% with the PL1, and in fact restored utility to the PL1. The carbon:nitrogen ratio of the original 2012 compost (C0) was 10.8:1, suggesting stability. It appeared that the main reason the C0 compost was inhibitory was that mineralization was slow or immobilization occurred, causing a lack of plant-available nitrogen, especially nitrate. Treatments with S lowered pH of the media, but there were no differences in basil seedling growth between the unamended 80% PL1:20% C1 blend and blends with added S. A fourth experiment compared three peat-lite media: PL1; a batch of the same medium as PL1 that was produced in 2013 (PL2); and a different medium also produced in 2013 (PL3). Peat-lite media were either used unblended, or blended with 20% C1 or 20% C2 (a fresh batch of YWC obtained from the same facility that had produced the original C0). The unamended PL1 was again inhibitory to basil seedling establishment and development. The two “fresh” peat-lite media (PL2 and PL3) were not inhibitory and were similar to each other in performance. A blend of 80% PL2 or 80% PL3 with 20% compost produced similar (C2) or somewhat better (C1) results than were obtained with the unamended peat. We conclude that a blend of 80% peat-lite medium and 20% YWC can be used to produce basil transplants. However, producers must consider the quality of the peat-lite medium and the compost based on the age and composition of the components.

Hospital recording system guidelines or known as medical records. Failure to fill medical records has an impact on the quality of service and hospital accreditation. The purpose of this study is to see what factors are the cause of non-compliance in filling Medical Records in hospitals throughout Indonesia. Research is a systematic review. The source of this research data comes from the literature obtained through the internet in the form of published research results regarding the causes of the inability of medical record documents in hospitals from all journals that have been published and can be accessed via the internet. Data was collected from 15 April 2020-10 July 2020. The results of the analysis through document review showed that the factors causing non-compliance of filling medical record documents at the High Hospital were human resources which were 66.6%, there was no clear and firm policy of 33.3%, facilities that did not support were 22.2% and limited funds by 11.1%. It is expected that each hospital must have a clear and firm policy in dealing with non-compliance with filling out this medical record document. With a clear and firm policy on the condition of HR unpreparedness, the facilities and financial conditions which will also be regulated in the policy can also be overcome at the same time.

Nursery activities were one important step in producing quality seedling. This study used a very low quality Gmelina seed with germination value of 9.8%. This value affected the ability of plants in responding to treatment. Input technology of growing media treatment and biostimulan needed to improve the quality of seedling. Sample of media planting collected from IPB permanent nursery. Applications biostimulan was using to help increased amount of plant roots. This study used a completely randomized factorial design with 7 replications. Observations for 8 weeks after planting (MST) found the media's treatment plant and biostimulan has significant effect on the parameters of diameter, height and total dry weight compared to control. Compost was the best medium in this study who had the highest NPK value compared to other media. Biostimulan concentration of 4% was proved improving the quality of Gmelina seedling in all media by increased the compactness of the roots of seedlings. The percentage increased in root dry weight (BKA), the largest found in the media mix of compost and mud. The best treatment in improving the quality of seeds Gmelina found in compost media and biostimulan 4% on all parameters of growth.Keywords: biostimulant, root compaction, seedling quality
