Authors: Sandiyanto Sandiyanto , Helvinda Weni
Published: November 2021

ABSTRACT

 

Introduction: Optic disc pit is a rare congenital abnormality of the optic disc. It is generally appears in the third or fourth decade of life; however, cases of serous detachment in children have been reported. Treatment includes argon laser to the peripapillary region, macular buckling surgery, vitrectomy combined with laser and/or gas injection.

Objective: To report a case with optic disc pit maculopathy in a 13 years old child.

Case Illustration: A 13 years old male presented to us with complaints of blurred vision in right eye started a month ago. No history of trauma. On examination, her visual acuities were 20/50 right and 20/20 left eye. Both anterior segments were normal, with normal intraocular pressures. OCT imaging showed optic disc pit located temporally, with associated serous macular detachment in the right eye.

Result: After 12 weeks observation, there is no significant change in the examination of the visual acuity, fundus examination and OCT imaging.

Conclusion: Currently there is no universally accepted treatment for optic disc pit maculopathy because the pathogenesis is not yet fully understood. In pediatric cases, 3-6 months of follow-up before any surgical and invasive procedures is appropriate.

Published: November 2021

Indonesia merupakan negara agraris yang mayoritas dari penduduknya berprofesi sebagai petani. Faktor utama dalam bidang pertanian berkaitan dengan kualitas tanah. Kualitas dari tanaman dapat dipengaruhi oleh beberapa parameter salah satunya pH (tingkat asam dan basa). Pada beberapa kasus, pengukuran pH tanah dilakukan dengan memanfaatkan kertas lakmus. Di sisi lain, sistem sensor dan instrumentasi telah berkembang sehingga memungkinkan dilakukan penelitian mengenai digitalisasi pengukuran pH tanah. Berdasarkan hal tersebut, maka dilakukan desain bangun pH tanah digital berbasis mikrokontroller. Perancangan sistem elektronik menggunakan beberapa komponen yaitu LED, LCD, buzzer dan sensor pH. Komponen tersebut dihubungkan dengan mikrokontroller sesuai perintah yang diinginkan. Ketika input masukan dari sensor terbaca maka LED, buzzer, dan LCD memberikan respon berupa cahaya, bunyi dan tampilan nilai output. Untuk mengetahui tingkat akurasi dari alat yang dibuat, dilakukan kalibrasi sensor pH tanah dengan membandingkan nilai keluaran pH standar terhadap nilai tegangan ADC (Analog Digital to Converter) pada sensor. Selanjutnya, dilakukan pengambilan data dengan sampel yang berbeda. Apabila tanah bersifat asam, LED 1 dan buzzer akan  hidup serta berlaku sebaliknya. Hasil penelitian menunjukkan alat dapat mengukur pH pada range 3,5 -7 dengan error 2,40%,  untuk pH >8 error yang dihasilkan cukup besar sehingga alat ini cocok mengukur pH tanah dengan range <8.

Pasal 29 Vienna Convention 1961 menyatakan bahwa pejabat diplomatik tidak boleh diganggu gugat, tidak boleh ditangkap dan ditahan. Mereka harus diperlakukan dengan penuh hormat dan negara penerima harus mengambil langkah-langkah yang tepat untuk mencegah serangan atas diri, kebebasan dan martabatnya. Maka akibat yang timbul dari tidak boleh diganggu gugatnya (inviolability) seorang pejabat diplomat adalah kekebalan terhadap yurisdiksi negara penerima. Namun kekebalan yurisdiksi yang dimiliki oleh pejabat diplomatik ini dapat ditanggalkan oleh negara pengirim sebagaimana yang terdapat pada Pasal 32 Vienna Convention 1961. Artikel ini bertujuan untuk mengetahui bagaimana mekanisme dalam penanggalan kekebalan (immunity waiver) oleh negara pengirim terhadap pejabat diplomatik. Hasil penelitian menunjukan bahwa subjek yang berhak untuk menanggalkan kekebalan pejabat diplomatik yang melakukan pelanggaran di negara penerima adalah negara pengirim. Penanggalan kekebalan ini dapat dilakukan setelah adanya permohonan yang diajukan oleh negara penerima serta disampaikan oleh Kepala Negara, Menteri Luar Negeri atau Kepala Perwakilan Diplomatik dari negara pengirim.
Geophysical and Hydrogeological Investigations of Water Leakage from a Reservoir Dam to a Coastal Aquifer: The Lebna Case Study (Northeastern Tunisia)
Authors: Ouhichi Nejmeddine , Hamdi Radhouane , Fethi Lachaal , GABTNI Hakim , grunberger Olivier
Published: November 2021

In semiarid regions, dams are useful for surface water storage, sediment
sequestration, and aquifer recharge. Built in 1987 on the Cap Bon
peninsula (in northeastern Tunisia), the Lebna Dam is considered a good
example of a multifunctional reservoir. The dam feeds two important
irrigation networks, stores large sediment quantities, and allows a
significant recharge flow to the underlying aquifer. This work suggests
new leakage flow and dam-aquifer interaction characterizations through
the development of an approach that combines a water balance
calculation, geological field observations, groundwater monitoring, and
geophysical research. The hydrological balance calculation performed
over the 27-year monitoring period, from 1990 to 2017, shows that an
estimated water volume of 3.7 Mm3y-1 has leaked from the Lebna reservoir
to the coastal aquifer. Geological mapping of the Lebna Dam basin in
summer 2019 revealed the existence of permeable layers of sands to
sandstones exposed along the southern banks of the reservoir and
extending to an elevation that included the water level when the dam is
full; these rocks outcrop at approximately 16 m.a.s.l. A geophysical
survey based on 67 vertical electrical soundings and 8 electrical
resistivity tomography profiles in the area downstream of the reservoir
was carried out to identify the lateral continuity of the recharge
zones. Piezometric campaigns consisting of four field surveys in 2019
and 2020 were conducted in the region downstream of Lebna Dam,
consisting of 71 water well samples. An interpretation of these
geophysical data coupled with available borehole logging and piezometric
measurements was used to define the leakage geometry from the reservoir
dam to the coastal aquifer. The collected evidence led to the conclusion
that concentrated recharge occurs in the downstream sections, especially
on the right bank of the aquifer.
Warming soil temperature and increasing baseflow in response to recent and potential future climate change across northern Manitoba, Canada
Authors: Lilhare Rajtantra , Dery Stephen , Stadnyk Tricia , Pokorny Scott , Koenig Kristina
Published: November 2021

This study investigates the impacts of climate change on the hydrology
and soil thermal regime of ten sub-arctic watersheds (northern Manitoba,
Canada) using the Variable Infiltration Capacity (VIC) model. We utilize
statistically downscaled and bias-corrected forcing datasets based on 17
general circulation model (GCM) - representative concentration pathways
(RCP) scenarios from phase 5 of the Coupled Model Intercomparison
Project (CMIP5) to run the VIC model for three 30-year periods: a
historical baseline (1981–2010), and future projections (2021–2050:
2030s and 2041–2070: 2050s), under representative concentration
pathways (RCPs) 4.5 and 8.5. The CMIP5 Multi-Model Ensemble (MME)
mean-based VIC simulations indicate a 15–20% increase and 10%
decrease in the projected annual precipitation and snowfall,
respectively over the southern portion of the basin and
>20% rainfall increase over the higher latitudes of the
domain by the 2050s. Snow accumulation is projected to decline across
all sub-basins, particularly in the lower latitudes. Projected
uncertainties in major water balance components (i.e.,
evapotranspiration, surface runoff, and streamflow) are more substantial
in the wetland and lake-dominated Grass and Gunisao watersheds than
their eight counterparts. Future warming increases soil temperatures
>2.5°C by the 2050s, resulting in 40–50% more baseflow.
Further analyses of soil temperature trends at three different depths
show the most pronounced warming in the top soil layer (1.6°C 30-year-1
in the 2050s), whereas baseflow increases substantially by 19.7% and
46.3% during the 2030s and 2050s, respectively. These results provide
crucial information on the potential future impacts of warming soil
temperatures on the hydrology of sub-arctic watersheds in north-central
Canada and similar hydro-climatic regimes.

This work analyzes the existence of solution and approximate
controllability for higher order non-linear fractional
integro-differential systems with Riemann-Liouville derivatives in
Banach spaces. Firstly, the definition of mild solution for the system
is derived. Then a set of sufficient conditions for the existence of
mild solution and approximate controllability of the system is obtained.
The discussions are based on fixed point approach, and the theory of
convolution and fractional resolvent. To illustrate the feasibility of
developed theory, an example is given.

Published: November 2021

We provide new evidence on individual analysts' differential abilities to forecast firm value. We find that independent analysts' target prices perform well in predicting future price relative to investment-bank analysts. Our evidence suggests that, 12 months after issuance, independent analysts' target prices are more likely to be met than those issued by investment-bank analysts and are more accurate than the target prices of affiliated investment-bank analysts, controlling for analyst characteristics. However, we find that the association between realized returns and the returns predicted by target prices does not differ for independent versus investment-bank analysts. Our evidence contrasts with prior literature which generally concludes that independent analysts' research is of lower quality. Yet, the market appears to react relatively less strongly to independent analysts' target price revisions. Our findings suggest that investors and researchers can benefit from understanding the properties of independent analysts' target prices, particularly for certain types of firms.

Semanttinen parlamentti -hankkeessa 2020–2022 luodaan eduskunnan tietokannoista ja niihin liittyvistä muista aineistoista uudenlainen linkitetyn avoimen datan (Linked Open Data, LOD) palvelu, tietoinfrastruktuuri ja semanttinen portaali Parlamenttisampo – eduskunta semant­tisessa webissä, joiden avulla tutkitaan poliittista kulttuuria ja kieltä. Dataa linkittämällä voi-daan rikastaa eduskuntadataa muilla tietolähteillä kuten biografisella tiedolla, terminologioilla ja lainsäädännön dokumenteilla. Parlamenttisampo on kieli- ja semanttisen webin teknologioihin perustuva palvelukokonaisuus tutkijoita, kansalaisia, mediaa ja valtionhallintoa varten. Artik­kelissa esitellään hankkeen visio, ensimmäisiä tuloksia ja niiden hyödyntämismahdollisuuksia: Eduskunnan kaikkien täysistuntojen 1907–2021 yli 900 000 puheesta on valmistunut linkitetyn datan tietämysgraafi (knowledge graph); data on myös saatavilla XML-muodossa, jossa hyö­dynnetään uutta kansainvälistä Parla-CLARIN-formaattia. Ensimmäistä kertaa eduskunnan puheiden koko aikasarja on muunnettu dataksi ja datapalveluksi yhtenäisessä muodossa. Lisäksi puheet on yhdistetty eduskunnan kansanedustajien tietokannasta luotuun ja muista tietolähteistä rikastettuun toiseen tietämysgraafiin laajemmaksi ontologiaperustaiseksi datapalveluksi Fin- Parla. Datapalvelua voidaan käyttää eduskuntatutkimukseen parlamentaarisesta ja edustuksel-lisesta kulttuurista sekä poliittisen kielen käytöstä analysoimalla kansanedustajien täysistunnois­sa pitämiä puheita ja poliitikkojen verkostoja data-analyysin keinoin. Palvelun rajapinnan avulla voidaan myös kehittää eri käyttäjäryhmille sovelluksia, kuten hankkeessa valmistuva Parlament­tisampo.fi-portaali.

This study explores assessing as a social and digital activity in Twitter interactions on remote work. Digital interaction analysis of progressivity and sequentiality is used as a method that is based on online discussion research and applied conversation analysis. In hashtag #etätyö discussion participants are showing appreciation for the opportunity to work remotely, evaluating features of remote work, and advising remote workers through assessing forms and actions. Simultaneously, they progressively carry on and orient to the specific ‘hashtagged’ lines of discussion. In specific thread discussion participants organize assessing activity through positive and complementary, and occasionally negative, responses that are reciprocally and sequentially produced in line with the thread’s first tweet doing positive assessment. In conclusion, societally important issues should be assessed using jointly social and digital affordances available in the platform contexts. Furthermore, the study contributes to the discussion in digital humanities and social sciences on the importance of social interaction perspective.
Effect of the interrow width and plant density on the yielding of white lupin
Authors: Prusinski Janusz
Published: November 2021

The study investigated a Polish white lupin ‘Butan’, and its yielding depending on the interrow width and plant density.The mean many-year lupin seed yield was 3.05 t ha-1 and it strongly depended on the total rainfall and total temperature over the generative plant development. The mean discrepancy in the seed yield across the research years, due to a considerable variation in the total rainfall, ranged from 1.59 t ha-1 to 7.43 t ha-1. There was no significant effect of the factors applied on white lupin yielding. Only the number of pods per plant depended on the factors and it was significantly higher when lupin was grown in narrow rows, with the lowest plant density. Also, HI and SPAD values were significantly higher for 16 cm row width. The LAI value did not depend significantly on neither of the two factors. Content and yield of protein depended proportionally on the sum and distribution of precipitation in the following years.

Helicobacter cinaedi (H. cinaedi) is a Gram-negative curved motile rod that causes bloodstream or enteric infections. It was suggested that H. cinaedi was involved in the progression of atherosclerosis. We aimed to investigate the presence of H. cinaedi DNA using a nested-polymerase chain reaction (PCR) in atheroma plaques from patients with atherosclerosis-induced vascular diseases. A total of 129 patients diagnosed with valvular heart disease due to atherosclerosis and 146 patients with non-atherosclerotic post-stenotic dilatation were included as the patient and the control groups, respectively. The ATCC BA847 H. cinaedi strain was used as the positive control for the nested-PCR method. We investigated H. cinaedi DNA in our study groups using the nested-PCR method and detected only six H. cinaedi DNA (4.65%) in the 129 atherosclerotic patient group. We detected significant difference between patient and control groups with respect to the presence of H. cinaedi on the basis of Fischer’s exact test (p = 0.010) by univariate analysis. Age (OR: 1.042, p = 0.016), total cholesterol (≥200 mg/dL) (OR: 1.849, p = 0.0001), and high-density lipoprotein (≥50 mg/dL) (OR: 0.745, p = 0.039) levels were detected as independent variables for the risk of atherosclerosis development in the patient group. The presence of H. cinaedi was not detected as an independent variable in a multivariate analysis. Previous studies suggested that H. cinaedi-induced oral infections might translocate to vascular tissue and induce chronic inflammation in the aorta, which subsequently may lead to atherosclerotic plaque formation. In conclusion, we could not suggest that there is a causal relationship between H. cinaedi and the development of atherosclerosis. However, age (OR: 1.042), total cholesterol (≥200 mg/dL, OR: 1.849), and high-density lipoprotein (≥50 mg/dL, OR: 0.745, as protective) levels have a significant role in the pathogenesis of atherosclerosis development. We also suggest that the presence of H. cinaedi may contribute to the risk of atherosclerosis development due to the univariate comparison result.

Abstrakt

Receptory jądrowe (NRs) tworzą największą nadrodzinę czynników transkrypcyjnych, które odgrywają ważną rolę w regulacji wielu procesów biologicznych. Receptor kwasu 9-cis-retinowego (RXR) wydaje się odgrywać szczególną rolę wśród tej grupy białek, a to ma związek z jego zdolnością do tworzenia dimerów z innymi NRs. Ze względu na kontrolę ekspresji wielu genów, RXR stanowi bardzo dobry cel licznych terapii. Nieprawidłowości w szlakach modulowanych przez RXR są powiązane m.in. z chorobami neurodegeneracyjnymi, otyłością, cukrzycą, a także nowotworami. Istnieje wiele związków mogących regulować aktywność transkrypcyjną RXR. Jednak obecnie dopuszczonych do użytku klinicznego jest tylko kilka z nich. Retinoidy normalizują wzrost i różnicowanie komórek skóry i błon śluzowych, ponadto działają immunomodulująco oraz przeciwzapalnie. Stąd są stosowane przede wszystkim w chorobach skóry i w terapii niektórych chorób nowotworowych. W artykule przedstawiono ogólne wiadomości na temat RXR, jego budowy, ligandów i mechanizmu działania oraz potencjalnej roli w terapii nowotworów i zespołu metabolicznego.
Benign tumors of the large bronchi and trachea
Authors: Plaksin S. A.
Published: November 2021

The OBJECTIVE was to assess the incidence, diagnostic abilities and surgical tactics in case of benign tumors of the large bronchi and trachea.

METHODS AND MATERIALS. Benign tumors of the large bronchi and trachea were diagnosed in 29 (6.3 %) of patients among 445 patients with benign bronco-pulmonary tumors. The diagnosis was made due to X-ray and endoscopic studies. Lung resections were performed in 5 (17.2 %) patients. RESULTS. Clinical symptoms were non-specific. In 10 (35.7 %) cases, the disease was diagnosed during X-ray examination. Computed tomography revealed pulmonary changes caused by bronchial narrowing in 5 patients (17.2 %).The biopsy taken during bronchoscopy detected the histological form of the tumor in 16 (55 %) patients. The exact morphological type of the tumor was identified after its removal. More often, they were polyps (48.3 %), papillomatosis (20.7 %), chondromas (10.3 %), in single cases – teratomas, sclerosing hemangioma, adenoma, mucoepidermoid tumor, histiocytoma, inflammatory pseudotumors. In 24 (82.8 %) patients, tumors were removed during bronchoscopy by electrosurgical or argonoplasmic destruction methods. The repeated surgery for a recurrence was required in 5 (17.2 %) patients in terms of (8.3±4.7) months, three times for two patients. In three cases, we performed lobectomy; in one case, we performed lobectomy with wedge resection of the intermediate bronchus. Pneumonectomy was made in two patients: one patient suspected of cancer after tumor biopsy, the other – complicated with lung gangrene. The latter patient died of pneumonia of the single lung. The mortality rate was 3.4 %.

CONCLUSION. In presence of non-specific pulmonary symptoms resistant to therapy, it is necessary to rule out benign bronchial tumors using X-ray and endoscopy. Most formations can be removed during bronchoscopy. In case of irreversible lung changes or impossible endoscopic removal, we should use surgery.
