Authors: Laslo É. , György É.
Published: January 2019

Owing to their nutrient composition, dairy products ensure a favourable environment for different microorganisms. In our study, we investigated the microbiological quality of 22 different commercially available dairy products obtained from local stores and the open-air public market. Among the studied samples four were salty type soft cheese, two were fresh cheese, one was soft cheese (Mascarpone), one was feta-like cheese (Telemea), five were varieties of processed cheese, one was mozzarella, one was a semi-hard cheese, one was smoked cheese, five were cottage cheese, and one was a dairy spread. Samples were evaluated for the presence of Pseudomonas sp., total coliforms, Escherichia coli, Salmonella sp., Staphylococcus aureus, Bacillus cereus and Clostridium perfringens, yeast, and microscopic fungi.

Contamination level of the evaluated dairy products varied widely. Among the dairy samples one salty soft cheese, a processed cheese and one cottage cheese were the most contaminated, while low microbiological load was detected in the other samples.
The Water‑wastewater‑sludge Sector and the Circular Economy
Authors: Lipińska Danuta
Published: January 2019

The objective of this paper is a theoretical and empirical analysis and evaluation of the role, importance and opportunities of the water‑sewage‑sludge industry in the implementation of the circular economy. To realize this objective, a review of both the literature and the EU strategic documents concerning the subject of the study was conducted. The applied research method is a descriptive analysis based on available statistical data (Eurostat, EEA, EIO and the Polish Central Statistical Office) as well as on source materials. The theoretical part of the work presents the essence of the circular economy and the general characteristics of the analyzed sector, with a particular focus on the potential for the recovery of water from sewage and the reuse of wastewater, as well as the recovery of phosphorus from the wastewater treatment, processing and disposal of sewage sludge. The results of the study show that: (1) there are significant links between the development goals of the water‑sewage‑sludge sector and the circular economy. (2) it is necessary to seek and implement new solutions and technologies leading to the increased recovery of energy and biogens from sewage sludge. (3) there are still many barriers to the recycling of rainwater and graywater as well as to the reuse of wastewater. (4) the circular economy creates new opportunities for water‑sewage and sludge management at the local and national level.
Phylogenetic Uniqueness of Honeybee Apis Cerana from the Korean Peninsula Inferred from The Mitochondrial, Nuclear, and Morphological Data
Authors: Ilyasov Rustem A. , Park Junhyung , Takahashi Junichi , Kwon Hyung Wook
Published: January 2019

Apis cerana is an Eastern honeybee species distributed throughout Asia and closely related to the Western honeybee species Apis mellifera distributed across all of Africa, Europe and Western Asia, and subdivided into thirty confirmed subspecies. Currently, A. cerana is an endangered bee species in contrast to A. mellifera. We sequenced and annotated the complete mitochondrial genome of A. cerana from the Jeollanam-do province of South Korea and uploaded to the DDBJ/Genbank database(AP018431). MtDNA sequence is 15.925 bp long, has 84% AT-content and 16% GC-content and contains 22 tRNA genes, 13 protein-coding genes, two ribosomal RNA genes, one AT-rich region and four non-coding intergenic regions (NC1-4). All protein-coding genes are started by ATT and ATG codons, except the genes ATP8 and ND4, which started by ATC and ATA, respectively, and are stopped by the common codons TAA and TAG. A comparative analysis of the whole mtDNA sequences of A. cerana from Korea and Taiwan, A. c. cerana from China and A. c. japonica from Japan showed that the genetic divergence of the Korean A. cerana sample from subspecies A. c. cerana (2.57%) and A. c. japonica (2.58%) matched to the level of genetic divergence of mtDNA between animal subspecies (0.8-8%). Based on the comparative analysis of complete mtDNA (~16,000 bp), two nuclear gene VG and EF1- α sequences (~8,000 bp) and morphological measurements (six parameters), we assumed that Korean A. cerana, Chinese A. c. cerana and Japanese A. c. japonica are different subspecies at an early stage of sub-speciation and could be called further as subspecies of Apis cerana koreana.
Economic Value of Pollination Service of Agricultural Crops in Ethiopia: Biological Pollinators
Authors: Alebachew Getachew Worku
Published: January 2019

The most important ecosystem service for sustainable crop production is pollination, the mutualistic interaction between plants and animals. Honeybees are being indispensable role in this process. The total economic value of crop pollination worldwide has been estimated at €153 billion annually. Animal pollination of agricultural crops is provided by both managed and wild pollinators. The aim of this study was to determine the economic value of pollination services and vulnerability of Ethiopian agriculture in the face of pollinator decline. An improved approach to determine the economic value of pollination (EVP) services is applied to multiply a crop’s total value by a coefficient between zero and one representing the crop’s dependency on pollination services for production. The potential production value loss due to lack of pollinators is also computed as the ratio of EVP to economic production value. Then EVP was $ 815.2 million dollars and vulnerability of Ethiopian agriculture due to lack of pollinators 16% in the 2015/16 crop production season. The regional state of Oromia benefited the most followed by the regional states of Amhara and South Nation Nationality People (SNPP). Coffee, the leading crop, has the highest EVP in the country followed by Faba beans and Nug (Guizotia abyssinica). Ethiopia has highly benefited from biological pollinators, so protecting them has significant role in the country’s economy. Most crops in Ethiopia have no pollination dependency ratio and some minor crop has no production data, incorporating them possible to better estimation of EVP service for the future.

Authors: Tikhonova Marina , Ingver Anne , Koppel Reine
Published: January 2019

High molecular weight glutenin subunits (HMW-GS) of wheat are important factors in the determination of bread-making quality. They are responsible for elasticity and polymer formation of wheat dough. In the present study, 43 winter and 40 spring common wheat (Triticum aestivum L.) cultivars originated from Estonia, Belarus, Finland, Denmark, France, Germany, the Great Britain, Latvia, Lithuania, the Netherlands, Norway, Poland, Russia, Sweden, and New Zealand were characterised for Glu-A1 and Glu-D1 allelic composition using PCR method. Analyses were conducted with one DNA marker for identification of Glu-D1 allele encoding subunit Dx5, three DNA markers for Glu-A1 Ax1, Ax2* and AxNull subunits. It was determined that 32 (74.4%) winter and 35 (83.3%) spring cultivars had allele Glu-D1d, and 23 (53.5%) winter and 33 (78.6%) spring — Glu-A1a or Glu-A1b alleles, which have positive effect on dough properties. Polymorphism at Glu-A1 locus was detected in 15 cultivars, and 9 cultivars were polymorphic for locus Glu-D1. The obtained results were compared with published SDS-PAGE data. Complete or partial agreements were found for 78.1% of Glu-A1 and 70.6% of Glu-D1 alleles. Rapid and accurate identification of wheat Glu-1 alleles by molecular markers can be used for selection of wheat genotypes with good bread-making potential.

Published: January 2019

The aim of this study was to evaluate treatment of patients with moderate and severe heart failure (HF) who were resistant to pharmacotherapy in Latvia and to assess the cardiac resynchronisation therapy (CRT) by exploring the predisposing factors which provides CRT efficacy. We accomplished prospective analysis of left ventricle ejection fraction (LVEF) and other parameter changes 12 and 24 months after CRT device implantation, dividing the population into two groups: responders — to whom LVEF improvement was ≥10% and non-responders where ≥ 10% LVEF improvement was not achieved. The study included 50 chronic HF patients with preserved sinus rhythm, who underwent CRT device implantation in Latvia at the Pauls Stradiņš Clinical University Hospital from June 2009 to March 2012. In the group of patients where 12 and 24 months after CRT device implantation LVEF improvement ≥10% was achieved, there were statistically significantly more patients with left bundle branch block (LBBB) QRS morphology, wider QRS complex, nonischemic genesis of HF, and normal systolic blood pressure. Patients with LVEF improvement had more pronounced ventricular dyssynchrony measured by Echo before CRT device implantation and, accordingly, the CRT mode was programmed as left ventricle paced before right ventricle and close to 100% biventricular pacing was achieved and the patient was female.

Published: January 2019

This paper answers the question of how the construction of the meaning of the Peusijuek tradition is available in Aceh culture. Two important things that will support this thesis is how the mind and culture of Islam and Aceh combined into one formulated in a way. Therefore, how the processes, forms and philosophical meanings of the Peusijuek tradition available in Aceh culture will be discussed in this paper. The results of this study indicate that the Peusijuek tradition is one of the relics of Hindu Culture in Aceh. According to historical records, the implementation of the Peusijuek tradition before the sending of Islam still uses certain mantras and prayers. However, since the arrival and development of Islam in Aceh, the Peusijuek tradition has been changed by incorporating Islamic teachings in it, such as prayer, prayer, and other Islamic teachings. That is why the Peusijuek tradition in Aceh can still be up to now. In practice, the Peusijuek tradition is carried out by religious leaders and elders of Aceh, such as ulama, tengku, ustadz and ustadzah. This is done because the Peusijuek tradition is considered a sacred Acehnese procession. The practice of Peusijuek tradition in Aceh is carried out in religious and cultural activities, such as performing pilgrimage, marriage, circumcision, prayer, arena, buying new vehicles, and so forth. The purpose of this Peusijuek tradition is to appeal for the satisfaction, peace, happiness, and glory of the guests.

Stable assessment of the quality of similarity algorithms of character strings and their normalizations
Authors: Znamenskij Sergej Vital'evich
Published: January 2019

The choice of search tools for hidden commonality in the data of a new nature requires stable and reproducible comparative assessments of the quality of abstract algorithms for the proximity of symbol strings. Conventional estimates based on artificially generated or manually labeled tests vary significantly, rather evaluating the method of this artificial generation with respect to similarity algorithms, and estimates based on user data cannot be accurately reproduced.

A simple, transparent, objective and reproducible numerical quality assessment of a string metric. Parallel texts of book translations in different languages are used. The quality of a measure is estimated by the percentage of errors in possible different tries of determining the translation of a given paragraph among two paragraphs of a book in another language, one of which is actually a translation. The stability of assessments is verified by independence from the choice of a book and a pair of languages.

The numerical experiment steadily ranked by quality algorithms for abstract character string comparisons and showed a strong dependence on the choice of normalization.
Stereoselective Aminoiodination of Activated Alkynes with Organoiodine(III) Reagents and Amines via Multiple-Site Functionalization: Access to Iodinated Enamines and N-Aryl Indoles
Authors: arepally sagar , Katta Narenderreddy , Chamuah Ajoy , Duddu. S Sharada
Published: January 2019

A stereoselective aminoiodination of activated alkynes with PhI(OAc)2 and amines via multiple-site functionalization to afford (Z)diethyl 2-(diphenylamino)-3-iodomaleate derivatives with superior yields has been described. The key feature of this reaction is the incorporation of iodide and aryl group concurrently in the same molecule in a stereoselective manner by employing PhI(OAc)2 as electrophilic reagent as well as iodide and aryl group source. The high stereoselectivity of the reaction can be explained based on the structure of the possible intermediates, the conformations of which controlled by the hydrogen bonding, steric hindrance and electrostatic attractions. This reaction proceeds under mild conditions, providing various dialkyl 2-(diphenylamino)-3-iodomaleates by a single operation starting from activated alkynes. The robustness of our strategy is revealed by making of bis (dialkyl 2-(diphenylamino)-3-iodomaleate) derivatives involving formation of four new C-N bonds and two C-I bonds with a single step. The synthesized inactive 3° enamines (dialkyl 2-(diphenylamino)-3-iodomaleates) could be further transformed into highly substituted indoles via Pd catalyzed C-H and C-I activation under non-acidic conditions.

As at 12 November 2018, an outbreak of West Nile virus (WNV) was responsible for 139 WNV infection cases in Israel. Here, we characterise the epidemiology of the outbreak and demonstrate that only WNV lineage I was circulating in mosquitoes and responsible for WNV infection in humans. This suggests that the concurrence of the outbreak in Israel with WNV outbreaks in several European countries is not due to a common, more virulent WNV genotype.

Authors: Mulsandi Adi , Kristianto Aries , Zakir Achmad
Published: January 2019

Wilayah Banjarnegara terekspos dengan kejadian tanah longsor yang terjadi hampir setiap tahun. Hujan lebat merupakan salah satu faktor penting pemicu terjadinya longsor yang paling mungkin untuk diprediksi, sehingga prediksi hujan lebat yang akurat sangat dibutuhkan dalam sistem peringatan dini longsor. Namun demikian, keterbatasan peralatan pengamatan cuaca di Banjarnegara memberikan kendala tersendiri sehingga dibutuhkan teknik lain dalam pembuatan informasi prediksi cuaca di wilayah ini. Penelitian ini dibuat untuk memberikan kontribusi landasan ilmiah dalam membuat prakiraan cuaca menggunakan model Weather Research and Forecasting (WRF) dengan mengintegrasikan data pengamatan satelit menggunakan WRF Data Assimilation (WRF-DA) untuk memperbaiki kualitas data awal model. Hasil penelitian menunjukan bahwa prosedur asimilasi data satelit cuaca dapat memperbaiki data awal kandungan uap air di atmosfer (+60%) beberapa jam sebelum kejadian hujan lebat. Sehingga hasil prediksi model cuaca numerik dengan menggunakan asimilasi data satelit (DA-SAT) menjadi lebih baik dibandingkan dengan yang tidak menggunakan asimilasi data (Non_DA). Hal ini ditunjukan dengan nilai bias model yang mengecil (-32%) jika dibandingkan dengan data pengamatan penakar hujan stasiun. Hasil perbandingan data series waktu akumulasi curah hujan antara DA-SAT dan Non-DA memperlihatkan adanya perbedaan waktu tercapainya hujan maksimum dan juga perbedaan intensitasnya dimana skema Non-DA lebih lambat (+5 jam) dengan bias (-40%) sementara DA-SAT lebih lambat 0.5 jam dengan bias (+8%). Dapat disimpulkan bahwa asimilasi data satelit dapat memperbaiki kesalahan prediksi jumlah hujan dan waktu kejadiannya. Hasil penelitian ini dapat dijadikan rekomendasi penggunaan asimilasi data satelit dalam pembuatan informasi prediksi cuaca numerik di wilayah Banjarnegara.

Fourteen compounds were isolated from acetone extracts of three species of seaweeds (Eucheuma serra, a red seaweed, Halimeda opuntia, a green seaweed, and Hydroclathrus clathratus, a brown seaweed) using bioautographic TLC methods and identified using GC-MS. From Eucheuma serra were isolated 8 compounds (3 fatty acids, 3 steroids, and 2 aldehyds). Only two compounds of fatty acid camefrom Halimeda opuntia, whereas Hydroclathrus clathratus produced 6 compounds (4 fatty acids, one compound each of steroid and ether). All isolated single compoundswere tested for their antibacterial activities by the agar diffusion method against the Gram-positive bacteria Staphylococcus aureus, Bacillus subtilis and Streptococcusfaecalis, and the Gram-negative bacteria Echerichia coli, Pseudomonas aeruginosa and Salmonella typhimurium. All 14 compounds showed activity against Gram-positivebacteria, especially Bacillus subtilis, and only 2 compounds showed activity against Gram-negative bacteria Escherichia coli. Nine compounds showed activity against Staphylococcus aureus, and 4 compounds showed activity against Streptococcusfaecalis. All compounds were not active against Pseudomonas aeruginosa andSalmonella typhimurium bacteria. This study indicated that there is indeed a diversityboth in kinds and in molecular structures of the antibacterial substances.

Penanganan pengaruh bahaya tsunami bagi masyarakat pedesaan pesisir sangat penting, dengan bertujuan untuk mengurangi atau meminimalkan dampak kerugianatau kerusakan yang disebabkan oleh musbah tsunami tersebut. Namun, efek bencana alam tersebut mungkin tidak terlalu sering dianalisis dan dipertimbangkan dalam beberapa proyek perencanaan tata ruang di Indonesia. Hal ini disebabkan oleh kurangnya informasi dan data mengenai lokasi tersebut. Wilayah pesisir perlu dilindungi dari dampak tsunami dengan mempertimbangkan sejumlah besar orang tinggal disana dan kegiatan mereka. Adanya pembangunan dari program hutan mangrove oleh pemerintah yang lokal dan peningkatan perencanaan pesisir spasial akan membantu untuk meminimalkan bahaya seperti di pantai.

Water resource capacity in Java is significantly decreased. This has beennoticed by the more frequent floods and over-dried seasons happened inseveral locations in Java. On the other side, the water demand in Java israised as the result of increasing population and quality of live. Reducingof water resourcing capacity related with forest degradation, change ofland usage and river pollution. Interpretation of the satellite imaging in2005 showed that the vegetated land areas is left abaut 2,4 acre or 21%of the wholw area of Java island. This is lower than the regulatedrequirement, i.e. about 30%. Efforts might be needed to solve thisproblems, cover (1) Regulation of the number and distribution of population;(2) Forest and land rehabilitation; (3) Coasts degradation control; (4)Increasing efficiency of water usage and control of river pollution; (5)Management of land usage by implementing the required 30% area asopened green areas; and (6) Deregulation of the water managementinstitution.

Çevre kirliliğine neden olan kirleticiler, artan nüfusun paralelinde
gelişen sanayi ile birlikte hızlı bir artış kazanmıştır. Bu kirleticiler hem
doğanın dengesini bozmakta hem de canlıların sağlığını olumsuz yönde
etkilemektedir. Günümüzde bu kirleticilerin giderilmesi ilgili yapılan
çalışmalarda biyoremediasyon önemli bir yer kazanmıştır. Biyoremediasyon, bu
kirleticiler üzerinde çeşitli mikroorganizmaları kullanarak çevreye zararlı
olmayan ürünlere dönüştürmek için uygun maliyetli ve çevre dostu bir yöntem
olmaktadır. Özellikle de bu mikroorganizmalar arasında biyoremediasyonda
kullanılan funguslar, salgıladıkları enzimler ve/veya miselli yapıları gibi
özellikleri ile kirleticileri ayrıştırarak zararsız ürünlere
dönüştürdüklerinden dolayı oldukça dikkat çekmiştir. Bu derlemede, biyoremediasyon ve fungusların farklı ve yeni metabolik kapasitelerini tanımlayan farklı
yönleri ile biyoremediasyon potansiyelindeki rolünün ortak bir platformda bir
araya getirilmesi amaçlanmıştır.

Academic achievement as one of learning outcome indicator in adolescents influenced by the self and family environment factors. This study was aimed to analyze the effect of child characteristics, family characteristics, parenting style perceived by adolescents, self-efficacy and self regulated learning on adolescents academic achievement. The study used self report method which involved 91 eighth grade students from two junior high schools in Bogor. Data analysis included descriptive analysis and inference analysis (correlation test and linier regression test). Result showed that majority of samples perceived their parent as authoritative (86.8%) followed by authoritarian (11.0%) and permissive (2.2%). The result also showed that majority of samples had medium level in self-efficacy and self regulated learning. More than a half of samples had under average level in academic achievement. Correlation results showed that there were significant and positive relationship between authoritarian parenting style with birth order, family size as well as gender. Self regulated learning were significantly and positively related with authoritative parenting style (r=0.257, p-value<0.05) and self-efficacy (r=0.330, p-value<0.01). Meanwhile, regression results showed a positive effect of academic achievement on father's education (β=0.315, p-value=0.006) and authoritative parenting styles (β=0.259, p-value=0.014), as well as negatively on gender (β=-0.267, p-value=0.014) and permissive parenting style (β=-0.203, p-value=0.039).

Health is a major factor in community development. Inequality on health is most felt by people living in disadvantaged, outermost, and leading areas (3T) because of the difficulty of access to transportation and communication. Effective efforts are needed to achieve the optimal distribution of health services, one of which is by clustering 3T areas based on the ratio of health workers to see which areas are experiencing shortage of health workers and know the adequacy of the number of health workers spread in 3T areas. The object used in this research is 27 provinces 3T region in Indonesia and the applied statistical method is various hierarchical methods and Cluster Ensemble. Based on the results of this study, 3T area is divided into four clusters. The first cluster consists of 22 provinces and has good characteristics because all categories of the variables are in the medium category. The second and the third cluster consists of two provinces. The characteristics of the second cluster are good enough. The characteristics of the third cluster are not been good enough because there is one variable in the low category. The fourth cluster consists of one province and has characteristics that are not been good enough because there are several categories of the variables are in the low category.
