Authors: AZEEZ SHAMINA , KARUNAKARAN G , TRIPATHI P C , SHIVASHANKARA K S , ROY T K
Published: July 2023

Karonda (Carissa carandas L.) is a hardy, drought tolerant, low maintenance shrub, whose berries under-utilized but have potential to be promoted in the wastelands of India, and thus be of succour to farmers. The fruits are astringent due to high pectin content and therefore popular only as preserves. In this study the total phenol, flavonoid and anthocyanin contents and their individual components in three promising table collections of karonda: variety Konkan Bold, and promising collections CHES K-II/7 and CHES K-V/8 compared, and correlated with the antioxidant activity as determined by 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and Ferric reducing antioxidantpotential. The results indicated that these karonda collections are moderately good sources of phenols, flavonols and anthocyanins, the amounts of phenols and flavonoids correlated positively with the antioxidant activity. The phytochemical profile of individual components of the phenolic acids, revealed high concentrations of vanillic, protocatechuic, t-cinnamic, ferulic, chlorogenic, 2,4-dihydroxy benzoic, syringic and salicylic acids; flavonoids rutin,myricetin and umbelliferone; and glucosides of the anthocyanins cyanidin and pelargonidin. Further, CHES K-V/8 and CHES K-II/7 in addition to having favourable horticultural traits was superior to Konkan Bold, and may be recommended for release as varieties with health promoting polyphenols and antioxidant activity.

Export of agricultural commodities from India: Performance and prospects
Authors: SURESH A , MATHUR V C
Published: July 2023

Indian agricultural export has undergone significant changes during recent times. In this context, the present study has analysed the trend in exports of agricultural commodities from India, the changes in the comparative advantage, the Indian agricultural export scenario has witnessed during the past decade and the prospects for further boosting the agricultural export. There was significant rate of growth of export during the past decade; with wide difference across various commodity groups. The growth was 41.5% in case of guargum and other resins; 27% in meat and offals; 26.6% in case of meat and meat products; 24-25% in case of sugar and spices and 16.4% in case of cereals. The rate of growth was low in case of fish and marine products, tea and coffee. The differential trend growths have resulted in the changes in the composition of export. The study finds a significant increase in the share of export of cereals from (3.3 to 6.9%), guargum and other resins (1.0 to 7.5%), cotton (14.1 to 17.3%), spices (2.3 to 3.3%), and sugar (3.9 to 4.3%). On the other hand, the share has declined in some commodities- the notable one being fish and marine products (14.0 to 7.6%), fruits and nuts (6.1 to 3.5%) and coffee and tea (5.4 to 3.5%). The study has also analysed the comparative advantage of India's exports, through revealed comparative advantage (RCA). The RCA was improving in case of cotton, maize, and certain fruits and vegetables over time, but declining in case of some spices, rice and wheat. In case of plantation based spices and other commodities, India is gradually losing its comparative edge, mainly to Asian countries. The study has so identified yield improvement through growth in total factor productivity (TFP) as a potential factor that would result in generation of exportable surpluses and boosting India's export.

Published: July 2023

The present experiment was conducted to evaluate the yield and economic gain in cultivation of coloured capsicum (Capsicum annuum var grossum (L.) Sendt) hybrids in different protected structures. Six hybrids of coloured capsicum, i.e. Indra, Natasha, Bomby in red coloured group and Orobelle, Swarna, Kanchan in yellow coloured group were tried in 3 different types of protected structures compared to open field (OF) conditions. It was found that protected technology significantly enhanced crop duration (300) days in fan-pad cum force ventilated polyhouse (FFVP), 265 days in naturally ventilated polyhouse (NVP),250 days in insect proof net house (IPNH) as compared to 200 days in open fields. FFVP technology registered maximum fruit weight and yield (1.98 kg/plant, 11.83 kg/m2) followed by NVP(1.75 kg/plant, 10.42 kg/m2), IPNH(1.11kg/plant, 6.68 kg/m2) and OF (0.33 kg/plant, 1.98 kg/m2), respectively. Economic analysis of different protected structures exhibited considerably higher net returns of Rupees 247.33/m2 in FFVP, Rupees 309.67/m2 in NVP,Â Rupees 86.43/m2 in IPNH andÂ Rupees 14.75/m2 in OF condition. The benefit cost ratio was calculated as 1.73in FFVP, 2.47 in NVP, 1.48 in IPNH while the lowest value of 1.32 in OF condition. Disease incidence cum mortality of plant (2.43%) was minimum in all capsicum varieties grown under FFVP, while it was higher in NVP (6.52%) followed by IPNH (9.75%) with maximum in OF (43.65%). Whereas blossom end rot of fruits was minimum in FFVP (2.98%) followed by OF (3.28%). It is evident from the results that protected structures enhanced the production of coloured capsicum as compared to open field condition particularly during off-season in plains. Further, among different hybrid varieties evaluated, Indra in red group and Orobelle in yellow group are found more suitable for growing in these conditions while Bomby and Swarna were also performed at par under protected structure.

Published: July 2023

The field experiment was conducted during rabi seasons of 2012-13 and 2013-14 at the Research Farm, School of Climate Change and Agricultural Meteorology, PAU, Ludhiana. Wheat (Triticum aestivum L.) varieties HD 2967, PBW 550 and PBW 343 were sown under two row direction, viz. North-South (N-S) and East-West (E-W). Yellow rust (Puccinia striformis f sp tritci) severity and incidence was recorded at weekly intervals. Disease severity index was higher (100%) during rabi 2012-13 as compared to 2013-14 (91%). Among different row direction the disease severity was higher under N-S row direction as compared to E-W row direction during both the years. Area under disease progress curve (AUDPC) was maximum in PBW 343 sown under N-S row direction as compared to other treatments. Among three varieties HD 2967 was highly resistant to yellow rust as it showed zero AUDPC. Highly significant value of R2 (0.91 and 0.90) was found when maximum meteorological parameters were combined in PBW 343 and PBW 550, respectively. Relationships were developed between microclimatic parameters, viz. canopy temperature and relative humidity. Analysis of these relationships indicated that disease and microclimatic parameters were interrelated. Higher R2 values of Humid Thermal Ratio (HTR), Special Humid Thermal Ratio (SHTR) and disease severity indicated that HTR and SHTR can be used as a disease predictor.

Economic development aims to increase people's purchasing power by increasing their standard of living with employment opportunities that can be supplemented by local jobs, especially jobs that have a national impact on the economy, for other activities, and are expected to improve people's lives. Economic thought was born from the abolition of goods which, according to its founders, were deemed useless - ceteris paribus. The concept of competitive advantage is not the same as the concept of profit, the concept of profit is not the same as the concept of absolute value, and profit is a combination of the three. By definition, the concepts of comparative advantage and competitive advantage have different meanings. The analytical approaches used to measure value and create value from the two perspectives are also different. Achieving and maintaining an advantage over relationships and competition is the key to long-term corporate success, therefore, understanding corporate assets and behaviors that can lead to synergies and competitive advantage is an important issue in leadership research.

Approximate analytical solution of a (V,m,h) reduced system for backpropagating action potentials in sparsely excitable dendrites
Authors:   The Faculty of Mathematics and Natural Sciences, University of Oslo, Oslo 0316 Norway, Iannella Nicolangelo , Poznanski Roman R. ,   Integrative Neuroscience Initiative, Melbourne, Australia 3145
Published: July 2023

We derive an approximate analytical solution of a nonlinear cable equation describing the backpropagation of action potentials in sparsely excitable dendrites with clusters of transiently activating, TTX-sensitive Na+ channels of low density, discretely distributed as point sources of transmembrane current along a continuous (non-segmented) passive cable structure. Each cluster or hot-spot, corresponding to a mesoscopic level description of Na+ ion channels, included known cumulative inactivation kinetics observed at the microscopic level. In such a reduced third-order system, the ‘recovery’ variable is an electrogenic sodium-pump and/or a Na+-Ca2+ exchanger imbedded in the passive membrane, and a high leakage conductance stabilizes the system. A nonlinear cable equation was used to investigate back-propagation and repetitive activity of action potentials, exhibiting characteristics of the modified Hodgkin-Huxley kinetics (in the presence of suprathreshold input). In particular, a time-dependent analytical solution was obtained through a perturbation expansion of the non-dimensional membrane potential (Φ) for all voltage dependent terms including the voltage dependent Na+ activation μ) and state-dependent inactivation (η) gating variables and then solving the resulting system of integral equations. It was shown that back-propagating action potentials attenuate in amplitude with the frequency following experimental findings and that the discrete and low-density distributions of transient Na+ channels along the cable structure contribute significantly to their discharge patterns. A major significance of integrative modelling is the provision of a continuous description of the non-dimensional membrane potential (Φ) as a function of position.

Grammar as one aspects of the language is necessary to be studied. One of grammatical components is pronoun. Many students are still confused on the use of personal pronouns in translating sentences. Therefore, the researcher is interested to conduct the research about error analysis on the use of personal pronoun in translating sentence. The objectives of this research were to know the percentage of students’ error in using personal pronouns and to know what kind of personal pronouns error that is often made by the students of grade X SMK Nurul Fajeri computer network engineering major.

The method used in this research was qualitative case study. The population was all  ten grade students of SMK Nurul Pajeri ccomputer network engineering major, totaling 29 people.  The research sample was 14 students who were taken from 29 population. The instument used for the research were test and interviews. That consist of 25 question in the form of fill in the blanks for the test, and the interviews for both students and teacher.

The results of the obtained was sufficient. this is proven from the personal pronoun percentage with the results of: Subject pronoun category 32 items with percentage of 8.65%, object pronoun category 71 items with a percentage of 19.19%, possessive pronoun category 74 items with a percentage 20%, possessive adjective category 66 items with a percentage of 17.84, reflexive ccategory 67 items with a percentage 18.11%, and a transalting 60 items ith a percentage of 16.22%. The most dominant results are wrong in the personal pronoun in the possessive pronoun category. The findings of this study indicate that there are still many students who experience errors in grammmar, especially personal pronouns. The results of the study show that the errors occur in students come from themselves, due to a lack of confidence and this also affects the translation in personal pronoun.

Authors: Heydari Leila , Khalili Mohammad Ali , Rahimi Azam Agha , Shakeri Fatemeh
Published: July 2023

Objective: Reconstructed oocytes after polar body genome transfer constitute a potential therapeutic option for patients with a history of embryo fragmentation and advanced maternal age. However, the rescue of genetic material from the first polar body (PB1) through introduction into the donor cytoplasm is not yet ready for clinical application. Methods: Eighty-five oocytes were obtained following in vitro maturation (IVM) and divided into two groups: PB1 nuclear transfer (PB1NT; n=54) and control (n=31). Following enucleation and PB1 genomic transfer, PB1 fusion was assessed. Subsequently, all fused oocytes underwent intracytoplasmic sperm injection (ICSI) and were cultured in an incubator under a time-lapse monitoring system to evaluate fertilization, embryonic morphokinetic parameters, and cleavage patterns. Results: Following enucleation and fusion, 77.14% of oocytes survived, and 92.59% of polar bodies (PBs) fused. However, the normal fertilization rate was lower in the PB1NT group than in the control group (56.41% vs. 92%, p=0.002). No significant differences were observed in embryo kinetics between the groups, but a significant difference was detected in embryo developmental arrest after the four-cell stage, along with abnormal cleavage division in the PB1NT group. This was followed by significant between-group differences in the implantation potential rate and euploidy status. Most embryos in the PB1NT group had at least one abnormal cleavage division (93.3%, p=0.001). Conclusion: Fresh PB1NT oocytes successfully produced normal zygotes following PB fusion and ICSI in IVM oocytes. However, this was accompanied by low efficiency in developing into cleavage embryos, along with an increase in abnormal cleavage patterns.

Published: July 2023

Zoochemicals-mediated synthesis of copper oxide nanoparticles is related to phytochemical-mediated synthesis of nanoparticles, in which act as reducing agents in nanoparticle synthesis. Zoochemicals are animal compounds that are equivalent to phytochemicals in plants. Today’s nanotechnology is a promising approach for the agricultural industry as an alternative source of pest management with specific targets and reducing environmental adverse effects. The aim of the present study is to investigate the insecticidal activity of Hyattella intestinalis extract, Zoochemicals mediated synthesis of copper oxide nanoparticles and molecular docking. The primary target of AChE is inhibited by Z-CuONPs and Hyattella intestinalis extract to cause toxicity in the Tribolium castaneum insect, and AChE inhibitory activity was directly dose-dependent on Zoo-extract and Z-CuONPs (R2 = 0.982 and 0.967), respectively while the IC50 of Zoo-extract (141.10 µg/ml) and CuONPs (118.92 µg/ml), caused the toxicity of the target pest. The index of repellency (IR) was less than 1 (IR < 1) for Z-CuONPs and Zoo-extract which is a response to the significant reduction of the Tribolium castaneum population and statistically agrees with the Chi-square test (X2). The computational approach to the identification of potential protein targets by CuO with binding interactions of Tribolium castaneum odorant binding protein results in novel insect repellent compounds that contribute to reducing storage grain damage and behavioural responses of the target pest. Among the Z-CuONPs and Hyattella intestinalis extract, Z-CuONPs have potential insecticidal activity against Tribolium castaneum. This is the first scientific report recording zoochemical-mediated synthesis of copper oxide nanoparticles using Hyattella intestinalis extract.
The Assessment of the Toxic Effects of Bisphenol A (BPA) on Physiology and Reproduction of the Fish Species Oreochromis mossambicus
Authors: Meghwal Purushottam , Gupta Anuja
Published: July 2023

The industrialized world produces massive amounts of plastic every year. Recent research information suggests that BPA exhibits hormone-like properties, raising concerns about its suitability in some consumer products and food containers. The most important human exposure route to BPA is diet, which includes consumption of unclean food and water. Exposure to BPA has resulted in adverse effects on reproduction, embryonic development, and the onset of genetic abnormalities in both aquatic and terrestrial animals. However, reports of the effects of BPA on reproductive physiology in fish are limited. This study was aimed to study the adverse effect of BPA on the regulation of reproductive genes in Mozambique tilapia (Oreochromis mossambicus) fish species. The tissue distribution patterns of GnRH1 and GnRH1 in adult Oreochromis mossambicus are shown in predominantly expressed in brain tissues but after the exposure of BPA the gene expression were reported down regulated.  When t test was applied on the obtained data we have reported the statically significant down regulation of the GnRH2 (t test   P = 0.0395) after the exposure of BPA 5mg BPA/L. This study showed the adverse effect on the reproductive genes of the Oreochromis mossambicus.
Égtáji kitettségből adódó különbségek erdőszegélyek fajösszetételében és szerkezetében
Authors: Papp Mónika
Published: July 2023

Vizsgálatainkat Budakeszi mellett egy cseres-kocsánytalan tölgyes (Quercetum petraeae-cerris SOÓ 1957) erdőállomány, illetve az ezzel szomszédos parlagterületek átmeneti zónájában, négy különböző égtáji kitettségű (ÉK, NY−DNY, D−DNY, DK) erdőszegélyben végeztük. Erdőszegélyenként három-három merőleges transzektet jelöltünk ki, melyeken belül az erdőbelsőben, az erdőszegély egyes részeiben (lágyszárú szegélysáv, cserjés szegélysáv, erdőköpeny), illetve a szomszédos nyílt területen lévő mintanégyzetekben BRAUN−BLANQUET módszer segítségével határoztuk meg az egyes fajok borítás-gyakoriság (A−D) értékét. Az erdőszegélyek fajösszetételének és szerkezetének az erdőállománytól, illetve a parlagterületektől való eltéréseit az égtáji kitettség függvényében vizsgáltuk. A négy különböző kitettségű szegély esetében jelentős különbségeket találtunk mind a fajösszetételben, mind a szerkezeti jellemzőkben.
A Magyarországon előforduló meghatározó jelentőségű és gyakori talajtípusok fitolit profiljának katasztere IV. : A vizsgált Csernozjom és szikes talajok eredményei
Authors: Pető Ákos , Barczi Attila
Published: July 2023

A magyarországi jellegzetes talajok fitolitprofiljának kataszterét bemutató cikksorozatunkban egyrészt a gyakori talajtípusok fitolit-összetételét kívántuk feltárni (rekonstruálva ezzel növénytakarójukat), másrészt megkeresni összefüggéseiket a talajtani folyamatokkal, a talajképző tényezők egymásra hatásával. Igyekeztünk figyelembe venni az ember tevékenységét is, ezért a természetesnek tekinthető vegetációtípusok mellett az adott talajra jellemző tájhasználati formát (szántó, legelő stb.) is felvételeztük. Jelen munkában a csernozjom és szikes talajok vizsgálati eredményeit mutatjuk be. Mindkét főtípus a száraz füves puszták és sztyeppek fitolit-örökségét hordozza. A csernozjomokban a művelés hatására a termesztett növények fitolitspektruma vált dominánssá, de a természetes gyep alatt felvett szelvény fitolitjai gazdagon illusztrálták a füves pusztákat. Ezek a fitolitok az utóbbi esetben a csernozjom talajok indikátorainak is tekinthetők. A szikesek esetében is kirajzolódott a szikes gyepek képe, de ennél a főtípusnál alkalmunk nyílt megfigyelni a talajképződési folyamatok (agyagosodás, kilúgzás, szikesedés, kémhatás lúgossá válása) módosító hatását is, amely jelentősen befolyásolta a szelvények fitolitprofilját. Összességében a száraz puszták és sztyeppék jellegzetes talajainak fitolit-összetételét, valamint a talajgenetikai folyamatok és tájhasználati módok módosító hatását is sikerült feltárni.
Az elsődleges és másodlagos mezsgyék növényzetének összehasonlító vizsgálata a battonyai Gránic és Csárda-dűlő példáján
Authors: Csathó András István
Published: July 2023

A tanulmány két, egymás közelében, nagyjából párhuzamosan futó, egyaránt 4,140 km hosszú, hasonló szélességű, ugyanakkor eltérő eredetű mezsgyeszakasz hajtásos növényzetét hasonlítja össze. A „Gránic” Battonya ősi határmezsgyéje, a „Csárda-dűlő” egy kb. a 19. században kijelölt földút. A két mezsgyéről 2010 és 2011-ben, három bejárás során, összesen 171 hajtásos növényfaj került elő. A Gránicról 143 faj, a Csárda-dűlőről 121 faj előfordulását sikerült kimutatni. Ebből 93 faj mindkét mezsgyéről, 50 csak a Gránicról, 28 pedig csak a Csárda-dűlőről vált ismertté. Noha a két mezsgyeszakasz egymás közvetlen közelében helyezkedik el, esetükben az élettelen környezeti feltételek igen hasonlóak, mégis a védelem alatt álló növényfajok mindegyike (Anchusa barrelieri, Inula germanica, Ornithogalum brevistylum, Sternbergia colchiciflora, Vinca herbacea), továbbá a természetvédelmi szempontból jelentős sztyeppfajok jelentős része (pl. Elymus hispidus, Euphorbia salicifolia, Thalictrum minus, Viola ambigua) rendre csak az elsődleges mezsgyének számító Gránicról került elő.
Az Alsó-Tisza-völgyi holtágak tipizálása tájszerkezet alapján
Authors: Molnár Zsófia
Published: July 2023

Az Alsó-Tisza-völgyi holtágak tájkarakterében a legfontosabb tényező a tájhasználati és tájszerkezeti jellemzők, a holtágakhoz kapcsolódó területek tájhasználata. A holtágakhoz kapcsolódó területek tájrészlet-típusra lehet csoportosítani. A holtágak partvonalához kapcsolódó területek, belső részek egykori és aktuális hasznosítása, befolyásolják az adott holtág tájképi megjelenését, tájkarakterét és állapotát egyaránt. A tájszerkezet legfontosabb elemei az adott, uralkodó tájhasználat, a növényborítottság és beépített, művelt felületek aránya. Ugyanakkor a területhasználatokat a holtágak elhelyezkedése (mentett oldal - hullámtér) határozza meg. A hullámtéren a terület mikrodomborzati adottságai (pl. mélyfekvésű területek, ármentes teraszok, árvízvédelmi töltések), illetve a Tisza árvízének elöntései, amelyek befolyásolják a tájhasználatok rendjét. A mentett oldalon a települések közelsége, antropogén felszínformák befolyásolják a holtágak menti területek tájhasználatát.
Landscapes of agricultural specialisation : A forgotten theme in historic landscape research and management
Authors: Renes Hans
Published: July 2023

Some of the most characteristic landscapes in Europe are the result of specialised types of agriculture. Although these landscapes are often cherished by the local population, they tend to be overlooked by most regional landscape classifications. This article, extending on the results of the EucaLand project, focuses on the historic landscapes of agricultural specialisation. It presents the history (main periods, life cycles) as well as the geography of these landscapes.

CASE REPORT: Multidrug-resistant Pseudomonas keratitis and sequential endophthalmitis treated with chlorhexidine and piperacillin-tazobactam
Authors: Lu Louisa , Shen Alice , DeBoer Charles , Mahajan Vinit , Lin Charles , Rose-Nussbaumer Jennifer
Published: July 2023

Purpose

To report the clinical course and treatment strategies employed in management of a case of multidrug-resistant Pseudomonas aeruginosa keratitis progressing to endophthalmitis. The drug-resistant strain was later traced to use of contaminated EzriCare Artificial Tears in a multi-state cluster outbreak.

Observations

A 57-year-old male patient with a history of Descemet stripping automated endothelial keratoplasty was referred for a culture-positive Pseudomonas corneal ulcer in the right eye that had been treated with several weeks of topical moxifloxacin, fortified vancomycin and tobramycin, and intravitreal injections for endophthalmitis. His cornea was cultured off of antibiotics and grew only rare Propionibacterium acnes. Topical antibiotics and steroids were reduced, but his condition rapidly deteriorated with leading to corneal melt, perforation, and endophthalmitis. Repeat corneal cultures and sensitivity analyses revealed growth of a strain of Pseudomonas aeruginosa that was resistant to fluoroquinolones, aminoglycosides, cephalosporins, monobactams, and carbapenems, and only intermediate susceptibility to piperacillin-tazobactam. The patient underwent a therapeutic penetrating keratoplasty and was subsequently initiated on an intensive regimen of topical chlorhexidine and polymyxin-B/trimethoprim. He also underwent a pars plana vitrectomy with anterior chamber washout, followed by serial injections of intravitreal piperacillin-tazobactam at a dose of 225 mg/0.1 mL. After 8 weeks of intensive treatment, there was gradual with healing of his ocular surface, regression of his hypopyon and posterior inflammation, and no signs of recurrent infection. A public health investigation ultimately revealed that his infection was one of several cases involved in a multistate cluster outbreak of extensively drug-resistant Pseudomonas ocular infections that were traced to the use of contaminated EzriCare Artificial Tears.

Conclusions and Importance

Multidrug-resistant keratitis and endophthalmitis caused by multidrug-resistant Pseudomonas keratitis requires consideration of nonconventional antimicrobial agents and experimental therapeutic alternatives. Topical chlorhexidine and intravitreal piperacillin-tazobactam are currently nonconventional therapies in the context of bacterial keratitis and endophthalmitis, but were safe and effective in the management of multidrug-resistant Pseudomonas aeruginosa ocular infection.

Iso Series Certification System on The Financial Performance and Performance
Authors: Widyastuti Tri
Published: July 2023

The objective of this study was to compare the financial performance and stock performance of companies with and without ISO series certifications. In this study, EVA (Economic Value Added) and financial ratios, particularly Debt to Equity, Return on Equity, and Return on Assets, reflect financial performance, while anomalous returns represent stock performance. This study utilizes data from 2011 to 2019 firm reports that have acquired ISO 9000 and 14000 series certification. The results indicate that organizations with ISO series certification and those without certification are comparable. There is no substantial difference between the EVA and ROE ratios' financial performance. Nevertheless, the DER and ROA financial performance ratios differ significantly. Moreover, there are considerable discrepancies between ISO corporations and non-ISO companies in terms of stock performance. The conclusion of the study is that there is no significant difference between the performance of companies that receive ISO certification and those that do not, as a result of insufficient research time, the fact that non-ISO companies already have good marketing management, and the lack of continued ISO implementation in companies that already have ISO certification.
